外文原文翻译: C#版ASP(动态服务器主页)是一种较新的技术,它已经过几个阶段的发展(进化).它是怎么诞生的呢?在七年前,它作为一种简单的方法来往普通网页里添加动态内容。

自从那时以后,它的发展势头强劲:作为高级网页程序的开发平台,包括:电子商务网站、基于事件驱动的门户网站和你在网上能看到的其他所有东西。

2.0 是ASP的最新版本,而且拥有最让人激动的更新。

在帮助下,在网络编程时,开发者不再把一大堆HTML源码和脚本代码杂乱地放在同一页面上。

你可以完全使用代码和工具(Visual Studio 2005)来创建网页程序。

这些创新的代价仅仅是多学一些东西。

你要学一些高级开发工具(Visual Studio)和工具包(the .NET Framework),而且你需要精通一门编程语言,如C#。

网络发展的演化因特网是在1960年末在试验中诞生的。

它的目标是:建立一个真实的、有弹性的信息网络——可以经受的起若干数量的电脑的崩溃,而不至于阻断其他电脑的正常通信。

经得起潜在的重大灾难(如核武器攻击)。

美国国防部提供了刚开始的研究基金。

最早的因特网局限在教育机构和从事国防的单位。

它因为作为学术研究的一种工具而繁荣,它让全球的研究人员可以彼此共享信息。

到了1990初,伟大的“猫”诞生了,它通过电话线工作,从此,因特网向商业用户打开了大门。

在1993年,第一个HTML浏览器诞生了,标志着因特网革命的到来。

我们很难把最早的网页称为网页序。

第一代的网页看起来更像小册子:主要由固定的H TML页面构成,这些也都需要手动修改。

一个简单的HTML页面有点像一个字处理文档——它包含了格式化的内容,可以在你的电脑上显示,但是并不完成其他任何功能。

上面的就是一个最简单的例子,文档包括头信息和单行文本。

一个HTML文档有两种类型的内容:文本和标记(告诉浏览器如何格式化)。

这些标记很容易辨认,因为它们总是出现在< 和 >之间。

选课系统英文作文

选课系统英文作文英文:Choosing courses is an important part of college life. As a student, I have experienced the process of selecting courses several times. In my opinion, a good course selection system should have several key features.Firstly, it should be user-friendly. The system should be easy to navigate and understand, with clear instructions and helpful feedback. This will ensure that students can make informed decisions about their course choices.Secondly, the system should be efficient. It should be able to handle a large volume of students and courses without crashing or experiencing delays. This will save students time and frustration, and ensure that they can select the courses they need without any issues.Finally, the system should be flexible. It should allowstudents to make changes to their course selections iftheir circumstances change, such as if they need to drop a course or switch to a different one. This will give students more control over their academic experience and help them to achieve their goals.In my experience, the best course selection systems are those that combine these features. For example, my college uses an online system that is easy to use, efficient, and flexible. I can easily search for courses by subject, time, and instructor, and the system provides me with feedback on my choices. If I need to make changes to my selections, I can do so quickly and easily.Overall, I believe that a good course selection system is essential for a successful college experience. It helps students to make informed decisions, saves them time and frustration, and gives them more control over their academic journey.中文:选课是大学生活中重要的一部分。

大学生在线选课调查英语作文

大学生在线选课调查英语作文The process of online course selection for college students is increasingly becoming a pivotal aspect of their academic journey. With the digital era in full swing, this method has proven to be both efficient and convenient. A recent survey conducted by our team shed light on the experiences and perspectives of participants regarding online course selection in universities.An overwhelming majority attested to the benefits brought about by online course selection, which significantly eased the burden and stress associated with manual registration processes. With just a few clicks, students can easily access an array of available courses, including crucial details such as class times, professors, and prerequisites. This not only simplifies the selection process but also enables students to make informed decisions about their academic trajectory.Furthermore, it was evident from the survey thatflexibility played a key role in endorsing online courseselection among college students. The ability to peruse through various class timings and plan schedules accordingly was lauded as a significant advantage. This flexibility also extends to the accessibility of information related to different courses, allowing individuals to weigh their options sensibly before making a decision.Despite these positive aspects, several concerns emerged during the survey. One prominent issue revolved around technical glitches and website malfunctions during peak registration periods. This frustration was voiced by many participants who experienced system crashes or delays while attempting to select their desired courses.Additionally, a subset of respondents expressed reservations about the lack of face-to-face interaction during the online course selection process. Theyhighlighted that physical interaction with academic advisors or professors often provides invaluable guidance that may not be fully replicated through digital means.Another noteworthy finding focused on disparities in available resources for students from different departments or faculties within the same university. While some departments boasted comprehensive online platforms with detailed information on courses and instructors, otherswere found lacking in this regard. This irregularity led to discrepancies in ease of access and overall user experience.An interesting trend identified from the survey was the growing demand for personalized recommendations based on individual academic goals and interests. Many respondents expressed an interest in algorithms or systems that could suggest suitable courses based on their previous selections or academic field.In conclusion, it is evident that online course selection has become an integral part of college life for students today. While providing pivotal advantages such as convenience and flexibility, it is imperative foruniversities to address technical issues and ensure equal access to resources across all departments. As technology continues to advance, adapting these systems to bettercater to student needs remains crucial for enhancing the overall academic experience at universities.Overall speaking is ever so captivating when you are carrying out research especially when delving into topics such as this one!。

This document aims to provide a comprehensive guide on the English vocabulary related to course selection, helping students better understand the information provided in course catalogs and make informed decisions. The document is organized into several categories based on the different aspects of course selection.2. Course Categories2.1 General EducationGeneral education courses are designed to provide students with a broad-based education and develop their critical thinking and communication skills. These courses usually cover a wide range of subjects, such as humanities, social sciences, natural sciences, and mathematics. When selecting general education courses, students may come across the following terms:•Core Requirement: Courses that are mandatory for all students in a particular degree program. Failure tocomplete these courses may result in failure to graduate.•Distribution Requirement: Courses that satisfy a specific category or area within the general educationcurriculum. For example, a course may fulfill thehumanities distribution requirement.•Elective: Courses that are chosen by students based on their personal interests or career goals. These courses usually do not fulfill any specific requirements but aretaken to gain additional knowledge or skills.2.2 Major RequirementsMajor requirements are the courses that students must complete in order to earn a degree in a specific academic discipline. When selecting major requirements, students may encounter the following terms:•Core Courses: Courses that are essential to the understanding of the major field. These courses provide foundational knowledge and skills.•Concentration: An area of specialization within a major field. Students may be required to take specificcourses within the concentration area.•Prerequisite: A course that must be completed before taking another course. Prerequisites ensure thatstudents have the necessary background knowledge tosucceed in more advanced courses.2.3 Course LevelsCourses are often categorized into different levels based on their difficulty and the intended audience. The following terms are commonly used to describe course levels:•Introductory: Courses designed for students with little or no prior knowledge of the subject. These coursesprovide a broad overview and basic understanding.•Intermediate: Courses that build upon the knowledge gained in introductory courses. They delvedeeper into the subject matter and require a higher level of understanding.•Advanced: Courses that are more specialized and require a high level of proficiency in the subject. Thesecourses are typically taken by upper-level students orgraduate students.3. Course SchedulingWhen selecting courses, students need to consider various factors related to the course scheduling. The following terms are commonly used in course scheduling:•Time Slot: A specific time period during which a course is scheduled. This includes the days of the week and the start and end times.•Lecture: A course component in which the instructor delivers lectures and provides fundamental knowledge on the subject.•Lab: A course component that focuses on hands-on practical work, experiments, or research related to thesubject.•Seminar: A small-group discussion-based course that encourages active participation and in-depthexploration of a specific topic.•Online/Distance Learning: Courses that are delivered entirely online, allowing students to accesscourse materials and complete assignments remotely.4. Course DescriptionsCourse descriptions provide detailed information about the content and requirements of a course. When reading course descriptions, students may encounter the following terms:•Learning Objectives: The goals that students are expected to achieve after completing the course.•Syllabus: A document that outlines the course structure, learning materials, assignments, and evaluation methods.•Credits: The units of academic value assigned to a course. Students are often required to complete a certain number of credits to fulfill degree requirements.•Prerequisites: The courses or knowledge that students need to have before enrolling in a particularcourse.5. ConclusionThis guide has provided an overview of the English vocabulary commonly used in the context of course selection. By familiarizing themselves with these terms and phrases, students will be better equipped to navigate course catalogs and make informed decisions. It is recommended that students refer to their institution’s course catalog or academic advisor for specific guidelines and requirements related to course selection.。

From art and music to computer programming and entrepreneurship, the options are endless. It's like abuffet of knowledge, and we get to pick and choose what we want to feast on. It's a chance to explore our interests, discover new passions, and maybe even find our true calling.Overall, I think the new course selection system is a game-changer. It empowers students to take control of their education, fosters collaboration and practical learning,and offers a wide range of choices. It's a step towards a more personalized and engaging learning experience. I can't wait to dive in and start creating my own educational journey!。

SQL language is the main function of establishing ties with the various databases, for communication. In accordance with ANSI (American Nationa l Standards Institute) requirements,SQL as a relational database management system standard language. SQL statements can be used to implement a wide range of operations, such as updating the data in the database, extract data from the database and so on. At present, the vast majority of the popular relational database ma nagement systems suchas Oracle, Sybase, Microsoft SQL Server , Access, adopted the standard SQL language. Although many databases on the SQL statement for the redevelopment and expansion, but including the Select, Insert, Update, Delete, Create, and Drop, including the standard SQL commands can be used to complete almost all the database operations.SQL ServerSQL Server is a relational database management system. It was originally proposed by Microsoft Sybase and Ashton-T ate three companies jointly developed in 1988 with the introduction of the first OS / 2 version. After the introduction of Windows NT in, Microsoft and Sybase in the development of SQL Server on the split,Microsoft will migrate to SQL Server on Windows NT system, focusing on promoting the development of SQL Server version of Windows NT . Sybase is more focused on SQL Server in the UNIX operating system applications. SQL Server 2000 is Microsoft Launches the SQL Server data base management system, the inherited version of SQL Server 7.0 version of the merits, at the same time it increases than many of the more advanced features.

外文翻译---网上选课系统设计的关键技术及系统的构建

毕业设计外文资料翻译题目基于WEB的网上选课系统的设计与实现学院信息科学与工程学院专业网络工程班级学生学号指导教师二〇一二年二月二十五日Key Techniques for Web Course—Choosing SystemDesign and ConstructionAbstract:The Web Course—Choosing is the core that the credit system management reforms ,at present,the Web Course—Choosing system that every enterprises and colleges and universities already develop out,13o sttong or because of the diversity managing a pattern or because of system general availability,can be used being put in use directly having pretty big difficulty.Developed out the Web Course—Choosing adapting to our college credit system requires.In this paper,three key techniques of W eb Co urse~Choosing design were given:O0,system security。

Data optimized.Using JSP technology,the Web Course—Choosing system with the functions of data input,query,statistics was also given.Gave technical and methodology supports for understanding the Web Course—Choosing system structural design,making full use of current practical projects,and solving the practical problems as well as paved the way of implementation of the Web Course—Choosing system based credit support system.Key words:Web course—choosing ;system design;key techniques;construction IntroductionOnline course selection is an important part of teaching management of credit system, its characteristics can be summarized as a training model of diversity, autonomy of selective learning content, learning processes, learning flexibility of time and space. Flexible teaching management mode of a significant increase in impact of traditional, manual approach does not suit the new management mode, all colleges and universities in research to adapt to the new mode of teaching administration of network course selection system.At present, the College developed a system for close connection with the College teaching management mode, so the software versatility is not high, often only apply to colleges and universities. Software versatility of enterprise development was strong, but later maintenance and redevelopment more difficult. Based on the above reasons, Nanyang Institute of technology has developed online course selection system based on teaching management of credit system.1.Analysis of course-choosing system requirements1.1 S tudents on course selection system functional requirements analysisStudents in the courses of the requirements within the time period, log on to the systemas an optional course, by-election, in the course selection process to be able to query the professional teaching program, instructors, such as scientific research, after the end of the course to be able to browse individual curricula, while allowing students access to personal files and all subjects.1.2Teachers ' course-selecting system functional requirements analysisTeachers can use the system, maintain their own research and archival information, other teachers have access to part of the research, to be able to query your course schedule, can query the courses students, to entry the students, to on course score for statistical analysis, inspection under the teaching plan and teaching schedule, and so on.1.3Manager course-selecting system functional requirements analysisManagers use the system to develop the teaching plan, have access to teachingschedule tasks, have access to all courses, students and teachers have access to basic information, to carry out all kinds of statistics, and so on.2. Key technologies for design of network course selection system andmethod2.1 System design process2.1.1 Database designDatabase design is reasonable, is the key to the smooth running of the Office software system. Online course selection through to serious research, teaching and foreign colleges and universities in the province runs the entire process means of tracking the implementation of requirements analysis, design of the e-r model, associate system functions and data structures, and are reflected in the database design process. The system database reference 《education management information standard under》, combination I school actual of Senate teaching management mode for design, while meet relationship database of entity integrity, and reference integrity, and user defined integrity requirements, using main key and outside key implementation data of integrity, using since defined of constraints conditions to reduced entry of complex of and errors rate, using trigger mechanism enhanced reference integrity and control database of changes, using storage process reduced database development personnel workload, improve database implementation speed. Foreground and background common to access a database server systems, taking into account the large amounts of data the system itself (such as students ' basic information basic information basic information, courses, teachers and more than more than 40) and therelationships between data, in accordance with the relational database paradigm of 3NF, as much as possible but without redundant data interdependence.2.1.2Server configurationServer configuration requirements (with PC Server as an example):Operating system: Windows 2003, Linux, and UnixJava runtime environment-Jdk1. 3. 1Application server: Tomcat 4. 0 percentDatabase server: SQL Server 2000, Oracle 8i& Oracle 9i、Mysql3.23 PCServer hardware requirements:CPU: Intel PIII 800 or more (recommended P4 1. 6G)Memory: 512M (recommend 1G)Hard disk: 40G (reference 80G)Problem to focus on addressing the Security Server with the server configuration: (1) using the security features of the operating system, the operating system, such as users, user groups and access rights for strict rules, turn off services that may lead to security vulnerabilities, such as Telnet, FTP, SendMail, etc;(2) in respect of hardware disk array technology, guarantee the security of server-side data.2.1.3 Client developmentDevelopment tools use the most popular Web programming language of JSP and JavaBean and Servlet technologies used in conjunction. Its advantage program page once compiled, dramatically improves program speed, followed by its good cross-platform.2.1.4Commissioning and publishingOnline course selection in three stages, namely normal course, lessons confirmed election results, and a by-election. Trial operation of the System 2003-level undergraduate students, students in the school to fill out course selection form within the required time, selected courses, which lasted a week. Normal course after the end of Dean's Office in the normal course results to remove are not eligible for classes teaching 8 classes in, while another 4 course class class. Students can be viewed on the course-choosing system Web site was removed, fill out the course teaching class list information, confirm the election results. After withdrawal, combined classes allow re-election of the same category of students in other courses. Normal course results when processing is complete, 143 people have a by-election. Dean's Office Manager for by-election results are processed, are still not eligible classes of the class withdrawn(that is no longer offering the course next semester). Students on the course to confirm the results, you can log in course selection system to print their own curricula. Through the trial operation of the system and achieve the goal of college book, since 2004 in the hospital.2.2Design of key technologies and methods2.2.1Object-oriented programming technologyMethod of object-oriented programming is a kind of support software reuse and modular design method of practical programming, its basic idea is to encapsulate and scalability. Packaging to bring software modularity, security, and so on, because there is no data coupling, objects with no action taken as a result of boundary effects, therefore, easier to maintain and modify [. Scalability to leave system interfaces for easy integration with other systems, this system to work with the library, personnel management system management system, scientific management system, theInstitute of financial management systems, Office OA system integration, people of the smooth realization of data export.2.2.2System security technologyInformation security system construction of the first issue, of course-choosingsystem key information (such as student achievement, student information, and so on) safety is essential, must be developed at the design stage of the systemconstruction of reliable security policy. This system from network traffic, serversecurity, database management systems, systems, procedures, computer virusprevention and cure of the five regard provide security:(1) network communications: virtual local area network (VI, AN) services andfirewall technologies. Your WEB server and database server system on Collegecampus virtual subnet, only allow internal users to access, shielded external user access. For network protocol for qualifying, cute as h, p Protocol allows you toaccess, such as FrP, TeNet Protocol implementation.(2) Server security.(3) the database account permissions and database, database view, accountoperations record operating information, concurrency control, trigger actions, such as time tracking, in addition, enables automatic data backup data, and so on.(4) system. a.Designed to dynamically set the user information in your application,access information, illegal may be effective in preventing the program from thesystem the client logs on to the system, and b. Application security control fordatabase operations, will not cause half of the data submitted, or submitted error; c.Data encryption technology, the system user (such as students, teachers, and so on) registered passwords are encrypted to eliminate user Session such as technologygets the password.(5) computer virus prevention: install legitimate antivirus on the server side Withanti-virus and firewall software, ensure that the functioning of the system.2.2.3 Database optimization techniques.(1) SQL statement optimization: SQL statement into the same purpose to be poorperformance the performance of SQL statements. Using artificial intelligence,automatically overriding SQL statements, so as to find the best performance of anequivalent SQL statement.(2) indexed: improving query speed of the system.(3) create views and stored procedures3. Online course system construction3.1 Construction of management systemSystems using Microsoft SQLServer2000 database in the background, foreground mining technology of JSP+JavaBean+Servlet and B/S mode Tomcat5. 0 as a WEB server, Internet course-selecting system features such as data entry, modification, querying, and statistics.

US-China Education Review, ISSN 1548-6613February 2011, Vol. 8, No. 2, 220-232220Potential Use of Course Management Systems in HigherEducation Institutions in JordanMuhannad Al-Shboul The University of Jordan, Amman, JordanGiven the increased adoption of the CMS (course management systems) as an instructional tool, it is important toaddress the potential use of this technology in Jordanian higher education institutions. This study investigates thepotential to use CMS tools in instruction in the academic institutions in Jordan. This study does not seek to evaluatethe current use of computer mediated tools or their features in instruction. Its purpose is to investigate what iscurrently taking place with CMS in higher education settings. Therefore, the study does not seek to determine thevalue that the use of the CMS tools may have contributed to instruction, however, it identifies the level oftechnology integration as well as the level of the technology use in higher education and problems associated withits use among the faculty. This study identifies prevalent faculty attitudes and perceptions toward the potential useof CMS tools in higher education institutions, in general, and in Jordan, in particular.Keywords: course management systems, e-learning, Web-based learning, authoring toolsIntroductionCMS (course management systems) are fairly new software tools that have been used in an educational setting for around a decade. CMS are Internet-based software that manage student enrollment, track student performance, and create and distribute course content electronically. In this way, the CMS allow faculty members to manage their courses and use technology tools in their teaching, as well as enable them to extend the classroom beyond its traditional boundaries of time and space (Warner, 2003). The main purpose of CMS packages is to enable faculty to create course Web sites, that is to place course materials online and manage course activities (Kuriloff, 2001). In short, CMS are tools that faculty can use to create online course content (without knowing programming languages), communicate electronically with students and conduct assessments (Dabbagh, 2001).CMS became widely available in 1997, and their popularity and use have increased dramatically ever since (Rabinowitz & Ullman, 2004). CMS tools (such as blackboard, WebCT, Webboard, moodle and LiveText) have become invaluable tools for teaching with technology and have been widely adopted by many colleges and universities all over the world. In addition, courses that use CMS tools to deliver content are currently being integrated into instruction at a rapid pace (Green, 2002; Nelson, 2003). Three aspects of CMS make them extraordinary tools for ordinary instructors. First, the files are all kept on CMS servers. Second, it is invaluable to instructors that the entire course can be archived for future use. Third, they have the convenience that theMuhannad Al-Shboul, Ph.D., assistant researcher, Computer Center, The University of Jordan.POTENTIAL USE OF COURSE MANAGEMENT SYSTEMS 221users can access the course materials from anywhere at any time (Caplan-Carbin, 2003).One of the main advantages of CMS is that faculty can design asynchronous course activities and communication outside the face-to-face class (Widmayer, 2000). According to Rabinowitz and Ullman (2004), faculty have much to teach and explain to their students, but there is never enough time during a semester to cover all of what they want to cover. For this reason, they indicated that CMS were developed to help the faculty solve the time issue that they encountered during their lectures and assist them in course development and overall management using the Internet.However, “Effective use of CMS tools does not result from the use of the tools but rather from the integration of the tools in teaching” (Nelson, 2003, p. 3). If we are to understand and realize the potential use of such CMS tools in higher education in Jordan from a learning perspective, we must understand the perceptions of both faculty users and non-users of the CMS authoring tools. Consequently, as more courses require the use of CMS tools, as more funding is required to implement and support these classes, and as more time is required to develop and facilitate these courses, it becomes critical to understand why faculty choose to use or not to use these tools for their course support. In other words, we should examine the motivating factors for using CMS tools as well as the inhibiting factors from using CMS tools as perceived by the faculty members.Given the increased adoption of the CMS as instructional tools, it is important to address the potential use of this technology in Jordanian higher education institutions. This study investigates the potential to use CMS tools in instruction in the academic institutions in Jordan. In this regard, it is very important to point out that this study is just a direct reflection of the literature on the level of faculty involvement and the challenges that are associated with using CMS tools in higher education in general. Specifically, this study is considered as a cornerstone for another study, which will be conducted at the mid of September 2010 in one of the public universities in Jordan by the researcher to verify the findings of the reviewed literature as they revealed in this paper.In addition, because Jordan has almost the same academic atmosphere comparing to that of the international one; also, because Jordan is utilizing almost the same CMS and authoring tools, it is important to point out that the findings of this study are not only applied to the international academic institutions, but also applied to the academic institutions in Jordan as well.This study is organized into four parts. Part one introduces the significance of the study and describes the purpose of the study. Part two provides a literature review about the use of CMS in instruction and addresses a brief history of CMS in higher education and the related faculty perspectives. Part three describes what is currently taking place with CMS integration at higher education institutions and discusses what higher education administrations could do to improve the utilization of CMS tools at their campuses. And part four provides the findings of the study, conclusions and recommendations for future studies.Significance of the StudyA major thrust of education is integration of technology into teaching (Nelson, 2003). Technology by itself cannot be effective. Providing the latest technology to learners does not necessarily ensure improved learners’ participation or achievement. Additionally, technology does not necessarily improve instruction. Faculty’s attitude toward technology was found to be an important element in a successful integration of technology (Mitra, Steffensmeier, Lenzmeier, & Massoni, 1999; Nelson, 2003). It is important to investigate the level of technology integration in education, in general, and in Jordan, in particular; specifically, the faculty’s attitudesPOTENTIAL USE OF COURSE MANAGEMENT SYSTEMS222toward the utilization of CMS in their classrooms.In a recent study of technology innovations, Lynch (2002) found that, while 80% of colleges in his study have course management systems available, faculty only use these tools in 20% of courses offered. Why is such a low percentage of faculty members making use of CMS tools in educational settings? “Despite its potential benefits, the effectiveness of computer mediated communication when used to support learning in higher education is very variable, making it important to identify those factors which best predict successful implementations” (Tolmie & Boyle, 2000, p. 138). However, research indicates that one of the problems hindering the use of distance education tools (technology) in higher education is faculty resistance (Berge, 1998). Research is needed to explore the faculty perceptions about the use of CMS tools in instruction in higher education institutions.This study is valuable for the instructional technology leadership, because it establishes a cornerstone for any development training program for faculty technology integration at higher education institutions. Also this study is beneficial to instructional technologists in understanding faculty reluctance when diffusing new instructions or educational packages.The purpose of this study is to identify the issues and concerns of the use of CMS and similar tools in higher education. Specifically, the study, based on the reviewed literature, identifies the faculty’s perceptions about their use of CMS tools, identifies the factors that might be related to faculty use of CMS and investigates what higher education institutions can do to improve the utilization of CMS at their campuses.Research on faculty’s uses of technology in instruction is important, because educators who are comfortable about using technology model positive uses of technology to learners (Chiero, 1997; Kagima, 2001; Taylor, Torrie, Hausafus, & Strasser, 1999). Conducting research on faculty attitudes toward the use of CMS tools in teaching is important, because the findings will help understand technology integration.The importance of the obtained information can assist higher education institutions in determining the educational costs and value in terms of CMS effectiveness regarding the technology integration, because academic institutions spend millions of dollars per year on technology. Also, the obtained data can help in determining what academic institutions can do to improve technology integration (such as CMS) at their campuses. The obtained data can provide information about what academic institutions can do to reduce, minimize or overcome the obstacles to technology integration (such as CMS), because the level of technology integration has become a source of data upon which to evaluate university performance and reputation (Feeney, 2001).Identifying the level of technology integration in higher education and faculty’s attitudes and perceptions toward CMS in higher education may lead to a better understanding of the causes of reluctance to CMS use. This study helps fill in the gap in the current instructional technology knowledge base regarding faculty attitudes and perceptions concerning the use of CMS in higher education, as well as the level of technology integration in higher education.Additionally, the findings from this study assist faculty development directors when developing training programs for the faculty. Faculty training has been found to be an essential factor for successful implementation of new technology in higher education teaching and learning environments (Butler & Sellbom, 2002; Morgan, 2003; Ndahi, 1999).This study does not seek to evaluate the current use of computer mediated tools or their features in instruction. Its purpose is to investigate what is currently taking place with CMS in higher education settings.POTENTIAL USE OF COURSE MANAGEMENT SYSTEMS 223Therefore, the study does not seek to determine the value that the use of the CMS tools may have contributed to instruction; however, it identifies the level of technology integration as well as the level of the technology use in higher education and problems associated with its use among the faculty.Literature ReviewCurrent research indicates that many faculty members choose to integrate CMS tools for a variety of reasons. Some are interested in the convenience factor the tools provide for communication with students, while others are motivated because of administrative pressure. Whatever the reasons, most CMS tools are currently underexploited in teaching (Nelson, 2003).Many college faculty members are using CMS tools to supplement their traditional classroom instruction (Nelson, 2003; Warner, 2003). Clifford, Earp and Reisinger (2003) indicated that data published in Market Data Retrieval’s 2002-2003 Annual Survey of Instructional Technology Trends in Higher Education showed that 91% of colleges and universities reported using some type of CMS in 2002. Most of reviewed research indicated that the primary use of CMS tools is mainly for communication and convenience purposes (Dietz-Uhler & Bishop-Clark, 2001; Grandgenett, 2001; Mitra, Hazen, LaFrance, & Rogan, 1999; Nelson, 2003; Sherry, 1999; Strudler & Wetzel, 1999).Lewallen (1998) found that 100% of faculty surveyed used CMS communication tools in their daily life activities, but only about one-third of the same faculty used these tools in their teaching. Thus, “Some faculty members are simply unable to connect technology use to their teaching” (Nelson, 2003, p. 21). However, to many faculty members, technology use is often viewed as a separate activity and does not require the same forethought as traditionally formatted course tasks (Pierson, 2001). “Attitude toward technology and prior use of technology was found to be an important element” (Nelson, p. 21); therefore, “Faculty who possess a positive attitude about CMS tools are more likely to use them in instruction” (p. 21).“The influence of technology on teaching and learning is becoming more and more evident in educational institutions” (Ndahi, 1999, p. 21). The increasing availability of effective technology justifies investigating the level of faculty involvement, and the challenges that are associated with using these technologies. Some of these technologies are new to many institutions and faculty (Ndahi, 1999). Additionally, when people within an organization plan for using new or existing technology, there are several barriers to their efforts that they are likely to encounter. A consideration of the barriers faced by organizations may help organizational leaders find solutions to reduce or minimize these obstacles (Cho & Berge, 2002).According to Cho and Berge (2002), organizational cultures, norms and strategic planning influence the adoption and deployment of technology. Hence, most of the literature found that the need for faculty development and institutional support (encouragement and incentive) are consistently identified as primary factors influencing the use of new instructional technology at higher education settings (Butler & Sellbom, 2002; Morgan, 2003; Ndahi, 1999).According to Feeney (2001), CMS have been the focus of recent scholarly attention. As integrating technology into higher education becomes an institutional imperative at schools across the US, adoption of digital courses in new CMS becomes both an organizational goal and a source of data upon which to evaluate performance. Furthermore, Feeney (2001) stated that higher education institutions face persistent challenges in the use of technology, with the CMS being the latest technology challenge.POTENTIAL USE OF COURSE MANAGEMENT SYSTEMS224According to the 2003 Campus Computing project, more than 80% of universities and colleges in the US utilized CMS (Morgan, 2003). Harrington, Gordon and Schibik (2004) noted that perhaps no other innovation in higher education has resulted in such rapid and widespread use as the CMS. In the early of mid 1990s, faculty utilized a variety of Web-based tools to supplement course content and curriculum. Many faculty began using email and basic HTML (hypertext markup language) functionality in an attempt to increase interaction and enhance the teaching and learning process.Research indicated that one of the problems hindering the use of CMS in higher education is faculty resistance (Betts, 1998). Despite the expansion of distance education programs and its related technology across the US, many faculties are reluctant to participate in distance education or use its related technology, such as CMS (Olcott & Wright, 1995). Faculty’s reluctance has been linked to internal issues such as a lack of incentives and rewards systems to encourage faculty participation and a lack of an institutional framework to train distance teaching faculty (Lewis, 1985; Verduin & Clark, 1991). Betts (1998) stated that one of the primary factors that influences faculty participation in distance education and its related technology is the effect on faculty workload.According to Harrington et al. (2004), many universities, in an attempt to reduce the load on faculty, hired webmasters and instructional designers to assist faculty in creating more dynamic and learner-friendly instructional related websites. Several higher education institutions and commercial companies foresaw the need for more user-friendly approaches to put course materials on the Web and the need for increased availability to learners via the Internet. These entities began developing systems that would be relatively easy to use, requiring little or no knowledge of programming language (HTML, Java) and with the tools necessary to be useful for instruction. Between 1995 and 1997, several academic and commercial CMS applications were launched in the higher education market.These early CMS had only slight variations in available tools (Gray, 1998, 1999; Katz, 2003). Over time, a core group of tools were available with essentially all CMS. These core components included tools for synchronous and asynchronous communication, content storage and delivery; online quiz and survey tools, gradebooks, whiteboards, digital dropboxes and email communications (Harrington et al., 2004). While the majority of these tools are seen in the most commonly used CMS today, the robustness, flexibility and ease of use have generally all been refined. Furthermore, a vast array of additional components have been added, including mechanisms for just-in-time delivery and integration to front- and back-office administrative computing systems.Hannafin and Savenye (1993) examined some of the reasons why many instructors do not use, and sometimes resist, technology. They found that instructors may have felt threatened by change, so chose to resist it; they stated, “Fear is often cited as a reason for teacher resistance, even preventing some teachers from using any form of technology in the classroom” (p. 27). They also found that little formal effort was made to support instructors who tried to implement new technology. Wolski and Jackson (1999) indicated that there is a need for better representations of why some faculties adopt technology and why some faculties resist it.Katz (2003) reported that the past several years have witnessed the emergence of the CMS as an integral part of higher education’s instructional infrastructure. CMS have “become dominant elements of higher education’s system of educational delivery” (Morgan, 2003, p. 85). Green (1995) reported that 6% of all college courses used Web-based resources to support instruction; then Green (2001) found that 73.2% of the institutionsPOTENTIAL USE OF COURSE MANAGEMENT SYSTEMS 225sampled used CMS. Hence, “College and university campuses have and continue to designate resources to technology integration” (Nelson, 2003, p. 32). However, given the change that is required to integrate CMS tools effectively, timely faculty development, support and learning materials are gaining importance.Ely (2002) indicated that traditional approaches to teaching and learning in postsecondary environments continue to be a dominant force for a number of reasons: (1) professors hesitate to change; (2) some faculty do not have the skills to use information technology and are not especially eager to learn; and (3) there is an institutional reluctance to provide sufficient personnel and financial assistance to facilitate the use of networking. He noted that almost every technological development that has had potential for improving instruction has been confronted with barriers regarding user skill and confidence. Ely (2002) also indicated that potential users may be convinced that the technology has potential for improving learning, but the potential users are often reluctant to acquire the skills for using the new technology.In summary, the reviewed literature identified that the problems facing higher education faculty in integrating technology into their classes need to be addressed to improve the level of technology utilization. Furthermore, the reviewed literature identified that the level of CMS use has increased as faculty perspectives toward such technology have been addressed.Technology Integration in Higher EducationThis section addresses the level of technology integration in higher education and problems associated with its use among the faculty. “Technology is continuing to be a driving force in the delivery of education. Most college and university campuses have and continue to designate resources to technology integration. For faculty members, this is exciting and challenging” (Nelson, 2003, p. 32).While Ely (2002) indicated that “Faculty members at institutions of higher education have usually been late adopters of innovations for teaching and learning” (p. 11), Green (2000) pointed out that more college courses are using more technology resources. Green’s 2000 survey revealed that three-fifths (59.3%) of all college courses now utilize electronic mail, up from 54% in 1999, 44% in 1998 and 20.1% in 1995. Furthermore, the survey revealed that two-fifths (42.7%) of college courses in 2000 used Web resources as a component of the syllabus, up from 10.9% in 1995, 33.1% in 1998 and 38.9% in 1999. Moreover, Green’s 2000 survey revealed that almost one-third (30.7%) of all college courses had a Web page, compared to 28.1% in 1999, 22.5% in 1998 and 9.2% in 1996. Green’s 2000 Campus Computing Survey revealed that almost one-fourth (23.0%) of all college faculty had a personal Web page not linked to a specific class or course, compared to just 19% in 1999.The integration of technology in teaching in higher education has become an important issue (Nelson, 2003). Ely (2002) indicated that technology integration in instruction is one of the current trends in educational technology. In 2000, Green reported that there is a rising use of technology in instruction. The increasing availability of technology in instruction justifies investigating the level of faculty involvement, and the challenges that are associated with using these technologies (Ndahi, 1999).Green (2002) pointed out that courses use technology to deliver content are currently being integrated into instruction at a rapid pace. In the 2003 National Survey of Information Technology in US Higher Education, Green (2003) reported that a third of all college courses are using CMS tools, up from 26.5% in 2002, and 20.6% in 2001, and almost double the level in 2000 (14.7%). His survey data also revealed that over half (51.4%) of thePOTENTIAL USE OF COURSE MANAGEMENT SYSTEMS226respondents’ institutions had a strategic plan for developing CMS tools, compared to 47.5% in 2002.Green also reported that more than four-fifths (82.3%) of the participating institutions in his survey had already established a single product standard for CMS software, up from roughly three-fourths (73.2%) in the 2001 survey and 57.8% in 2000. He indicated that CMS are playing an increasingly significant role in instruction across all sectors. Green concluded that CMS tools have become an important component of the institutional instructional infrastructure: Both the percentage of classes that use CMS resources and the number of institutions that have established a campus standard for a CMS product are on the rise. Hence, as more instruction includes the use of these tools, issues in effective technology use become more important (Nelson, 2003). Investigating the level of faculty involvement and the challenges that are associated with using CMS have become essential issues in higher education.In regards to the challenges to faculty use of technology, Rogers (2003) stated that “Getting a new idea adopted, even when it has obvious advantages, is difficult” (p. 1). According to Rogers, “When new ideas are invented, diffused, and are adopted or rejected” (p. 6), social change occurs with certain consequences. Accordingly, adapting new technological innovation in higher education requires faculty to change their ways of teaching. Such change does not come easily (Schifter, 2000). Walsh (1993) stated, “Implementation of an innovation often requires change in the environment where it is introduced” (p. 52). Wolski and Jackson (1999) noted that adapting new technology, such as CMS, is not that simple. Some users will resist change entirely, with resistance to change in educational organizations being a widely recognized problem in the study of higher education.In this regard, Berge (1998) indicated that one of the problems hindering the use of new technology, such as CMS and distance education technology, in higher education is faculty resistance. Betts (1998) pointed out that research indicates that one of the problems hindering the use of distance education technology in higher education is faculty reluctance. In addition, Ely (2002) indicated that professors at higher education institutions hesitate to change. Rogers (2003) pointed out that anxiety, fear and resistance to change are natural phenomena when diffusing a new innovation, and that the attitudes and perceptions of users play an important role when such diffusion occurs. Marvin et al. (1999) stated about the situation most succinctly, “Faculty attitudes about instructional technology influence the successful implementation of technology in the classroom” (p. 4).“The gap between technology adoption and technology use in teaching has been noted worldwide” (Feeney, 2001, p. 11). Therefore, “Understanding the rate of adoption in any given situation requires analyzing factors that may facilitate the adoption and those that may operate as barriers to adoption” (Butler & Sellbom, 2002, p. 22). Ndahi (1999) indicated that the reasons which faculties are uncomfortable or resistant to using interactive computer-based instruction, such as CMS, in higher education institutions, are not made clear. Morgan (2003) found that some faculties are reluctant to adopt CMS.Holden and Mitchell (1993) indicated that faculty’s attitude is one of the obstacles that higher education institutions face. They stated, “The resistant attitude of faculty to using CMC applications, such as CMS, is an obstacle that will need to be overcome in order to ensure the success of future instructional CMC applications” (p. 36). Walsh (1993) indicated that the rate of adoption of distance education technology, such as CMS, in institutions of higher education, is slow. He also stated that faculty in institutions of higher education, and in particular, the attitudes of the faculty, are critical elements in the diffusion process.On the one hand, some scholars found that: (1) Some faculty are reluctant to adopt CMS, because they believe that the systems reduce their control of instruction and the instructional environment; (2) Training ofPOTENTIAL USE OF COURSE MANAGEMENT SYSTEMS 227faculty plays a key role in successful CMS adoption and use; (3) Strong leadership by campus executives and department chairs plays an important role in shaping and encouraging faculty to use CMS; and (4) The pedagogical impact of using CMS is perceived but difficult to measure.On the other hand, the findings of Ndahi’s (1999), Muilenburg and Berge’s (2001), Butler and Sellbom’s (2002), Anderson’s (2003) and Morgan’s (2003) studies showed that institutional support, encouragement and faculty training are essential factors for successful implementation of new technology in higher education teaching and learning environment. Clark (1993) found that department chairs, who will most influence future adoption and institutionalization of teaching innovations and new programs, were relatively positive in their attitudes toward the use of distance education technology and delivery tools when compared to other tenured and tenure-track university professors or other faculty at two-year colleges. Also, these studies indicated that, to successfully implement new technology in teaching and learning, educational institutions must address these barriers to faculty adoption. They also emphasized the need for further research to investigate faculty perceptions of CMS, to validate their findings and to analyze the utilization of CMS in higher education.Ndahi (1999) examined the extent to which distance learning technology is used by faculty in industrial and technical teacher education programs. He identified the variables or factors that contribute to faculty willingness or unwillingness to use interactive distance learning technology in industrial and technical teacher education programs. He also indicated that the reasons why faculty are uncomfortable or resistant to using interactive computer-based instruction (such as distance learning technology and course management systems) at higher education institutions are not made clear, thus, making it difficult to develop strategies to overcome the resistance if the reasons for instructors’ willingness or unwillingness to use these technologies are not understood. “Therefore, faculty and administration have to work together to identify, examine, and perform solutions so that the goal and mission of the institution, as well as the needs of the students, can be met” (Gammill, 2004, p. 30). However, he found that the most common reasons given by faculty for not using distance learning technology in their teaching are: (1) a lack of institutional encouragement, support and incentives; and (2) a lack of adequate training in the use of technology.Butler and Sellbom (2002) identified the factors that might affect faculty use of modern instructional technology. They identified the factors that faculty believes are important either in facilitating the use or in creating barriers that work against the use of such technology. They indicated that technology use needs more flexible and adaptive organizational cultures, norms and planning. They found that knowing how to utilize technology is the second most important factor in determining faculty use of modern instructional technology. However, they found that a lack of institutional support and a lack of time to learn new technology (workload) are the major factors affecting faculty use of technology.Rogers (2000) examined barriers to technology adoption. She found that barriers to successful technology adoption in education appear to have internal and external sources. Internal barriers may be summarized as “teacher attitude” or “perceptions” about a technology, in addition to a person’s actual competency level with any technology. External sources include the availability and accessibility of hardware and software, the presence of technical personnel and institutional support, and an appropriate and adequate program for staff development and skill building. Barriers that cross internal and external sources are lack of time, funding and the unique culture of the institution. Furthermore, Rogers found that “Attitudes and perceptions of key individuals in the academic institutions may become the major barrier to adopting any technology” (p. 467).。

关于选课系统利弊英语作文The Advantages and Disadvantages of Course Selection System。

With the advancement of technology, many universities and colleges have implemented an online course selection system to facilitate the process of choosing classes for students. This system allows students to select their courses, check their schedules, and make changes easily through a web-based platform. While there are many advantages to using a course selection system, there are also some disadvantages that need to be considered.One of the main advantages of a course selection system is that it provides students with the convenience of choosing their classes from anywhere and at any time. This eliminates the need for students to physically go to the registrar's office or stand in long lines to register for classes. Students can simply log in to the system fromtheir computers or mobile devices and select the coursesthey want to take. This saves time and reduces the stress associated with the registration process.Another advantage of a course selection system is that it allows students to easily access information about the courses being offered, including the course descriptions, prerequisites, and availability. This helps students make informed decisions about which classes to take and ensures that they are enrolling in courses that align with their academic goals and interests. Additionally, the system can provide students with real-time updates on course availability and any changes to the class schedule, allowing them to make adjustments as needed.Furthermore, a course selection system can help universities and colleges streamline the course registration process and improve efficiency. By automating the registration process, institutions can reduce the administrative burden on staff and allocate resources more effectively. This can lead to cost savings for the institution and allow staff to focus on other important tasks, such as academic advising and student supportservices.Despite the many advantages of a course selection system, there are also some disadvantages that need to be considered. One of the main drawbacks is that the system may be prone to technical glitches and errors, which can cause delays and frustration for students. For example, the system may crash during peak registration periods, preventing students from accessing the platform and registering for classes. This can lead to confusion and anxiety among students, especially if they are unable to secure a spot in a required course.Additionally, some students may struggle to navigate the course selection system and may require assistance from staff or advisors. This can be particularly challenging for students who are not tech-savvy or who have limited access to technology. In some cases, students may inadvertently select the wrong courses or overlook important information, leading to scheduling conflicts or academic setbacks.In conclusion, while a course selection system offersmany advantages, such as convenience, accessibility, and efficiency, there are also some disadvantages that need to be addressed. Institutions should strive to improve the usability and reliability of the system, provide adequate support for students, and ensure that the system meets the needs of all users. By carefully considering the pros and cons of a course selection system, universities and colleges can create a more seamless and effective registration process for students.。

外文翻译--论智能化的网上学习及管理系统应用

外文原文By intellectualized on-line study andmanagement system application1 network education administration system application present situationAccording to our country Ministry of Education data statistics, to 2003, our country had the nearly 3 ten thousand schools to establish the campus net, increased nearly 10 times two years ago, but, the statistical data also indicated that 90% campus network occupied one kind not yet put to full use the condition, the information technology education to apply far has not achieved the anticipated target. At present our country education administration system application present situation unsatisfactory reason are many, speaking of the network education administration system specification aspect, its subject matter has the following several spots.1.1 lacks the complete network education administration system specificationBecause lacks a set of complete network education administration system standard, therefore the system standard, incomplete, mutually is incompatible, carries on the system exchange with difficulty. Along with the nationwide network education administration system's gradual establishment, the massive information's value and the function obtain with difficulty manifest and display, some even become information trash.1.2software designs are not standardThe software is a network education administration system work important component, because lacks a set of perfect software design standard, all levels of education administration department and school develops or the software which purchases from the software company, the existence many design not standards, the compatible bad question.2 network education administration system system designNation science of education key topic "In Informationization Advancement Educational technique Development Research" sub-topic "Modern Distance learning High tech Characteristic And Intellectualized Tendency" initiating a project has provided the development network education administration system's rare opportunityand the comprehensive strength condition. Network teaching management system's research implementation, not only may raise the school system's management level, moreover can reduce the network education cost greatly, is the country makes the macroscopic plan and the macro-scientific policy-making in the personnel training aspect provides the support2.1 design mentality1)In the network teaching management system considered that the network university's each kind of concrete internal teaching educational administration management, the extraction general character, realize have the strong representative administration module;2)At the same time must consider these network university composes each kind of crosswise unified body - - - university dynamic alliance cooperation and cooperation relations design;3)Simultaneously provides the visit connection, so that the later higher authority Education administrative department can visit these connections through the higher authority management tool, thus obtains the subordinate network educational institution promptly effectively fast through the longitudinal channel the related information, carries on the surveillance and the correct directive instruction promptly.2.2 technical solutionsThe network education administration system is refers to take the network as the main medium, uses in supporting the teacher teaching and the student studies, can for the teacher, the student provide the information, the tool and the service system, it constitutes by the software system and the hardware system. The network education administration system besides has in the common computer network's basic function like shared network software hardware function, the email service, the file transfer service and so on, but should also have interactive, the instantaneity, openness, characteristics and so on resource sharing, as well as can provide the rich educational resources, to carry on functions automatically and so on education information management.3 network education administration system's function and architecture3. 1 network education administration functionNetwork environment's teaching with study is one involves each kind of personto participation, both has certain time span, and to have strongly “real-time” the request dynamic process. Teaching both sides may be in the different place in this activity. Is one uses in the teaching management based on the network teaching management system the software system, its management object is the network teaching activity entire process and all related essential factor, it takes the communication by the network the infrastructure, provides the service through the network to each kind of user. May summarize based on the network education administration system's function for the response, the monitoring, the direction, the appraisal. A network education administration system (Net - Basic Education Management System, NBEMS) has the following management function, the network education administration system also has is different with the traditional education management characteristic: Interactive, personalization and controllability.3. 2 network education administration architectureThe network education administration system faces the user has 6 statuses: The teacher, the student, the teaching management personnel, the teaching assistant, the system administration attendants as well as other personnel, like the exterior browsing, have not chosen the class student and so on. Looking from a service system's angle, its major function accepts the user service request, provides the corresponding service; Looking from a information management system's angle, it supports the network teaching activity and the management entire process information acquisition, the receive, the memory, the management, the transmission and the data analysis. The network education administration system architecture uses the client/server pattern generally (C/S) or the browser/server (B/S) the pattern. At the same time, system's client side many are the thin client, like this is advantageous in reduces the network load, raises the transmission speed. The network education administration function's execution majority is completes (this kind of pattern on the network education center server to need network data bank technology support, like ADO, JSP and so on). Therefore, the network education center server is the network educational system's core, it all-weather monitors the client side request, provides the prompt service for the system user, the management and distribution system's software and hardware resources, the control and the coordinated on-line study carries on smoothly, promotes each learner to decide the study goal realization, simultaneously also promotes system educational goal realization.中文译文论智能化的网上学习及管理系统应用1 网络教育管理系统应用的现状据我国教育部数据统计,到2003 年,我国有近3 万学校建立了校园网,比两年前增加了近10 倍,但是,统计数据也表明90 %的校园网络都处在一种没有充分利用的状态,信息技术的教育应用远未达到预期目标。

外文原文翻译: C#版ASP(动态服务器主页)是一种较新的技术,它已经过几个阶段的发展(进化).它是怎么诞生的呢?在七年前,它作为一种简单的方法来往普通网页里添加动态内容。

自从那时以后,它的发展势头强劲:作为高级网页程序的开发平台,包括:电子商务网站、基于事件驱动的门户网站和你在网上能看到的其他所有东西。

2.0 是ASP的最新版本,而且拥有最让人激动的更新。

在帮助下,在网络编程时,开发者不再把一大堆HTML源码和脚本代码杂乱地放在同一页面上。

你可以完全使用代码和工具(Visual Studio 2005)来创建网页程序。

这些创新的代价仅仅是多学一些东西。

你要学一些高级开发工具(Visual Studio)和工具包(the .NET Framework),而且你需要精通一门编程语言,如C#。

网络发展的演化因特网是在1960年末在试验中诞生的。

它的目标是:建立一个真实的、有弹性的信息网络——可以经受的起若干数量的电脑的崩溃,而不至于阻断其他电脑的正常通信。

经得起潜在的重大灾难(如核武器攻击)。

美国国防部提供了刚开始的研究基金。

最早的因特网局限在教育机构和从事国防的单位。

它因为作为学术研究的一种工具而繁荣,它让全球的研究人员可以彼此共享信息。

到了1990初,伟大的“猫”诞生了,它通过电话线工作,从此,因特网向商业用户打开了大门。

在1993年,第一个HTML浏览器诞生了,标志着因特网革命的到来。

我们很难把最早的网页称为网页序。

第一代的网页看起来更像小册子:主要由固定的H TML页面构成,这些也都需要手动修改。

一个简单的HTML页面有点像一个字处理文档——它包含了格式化的内容,可以在你的电脑上显示,但是并不完成其他任何功能。

上面的就是一个最简单的例子,文档包括头信息和单行文本。

一个HTML文档有两种类型的内容:文本和标记(告诉浏览器如何格式化)。

这些标记很容易辨认,因为它们总是出现在< 和 >之间。

HTML定义了不同级别的标题、段落、超链接、斜体和粗体格式、水平线等。

举个例子:<h1>某个文本<h1>,告诉浏览器用标题1的格式来显示这个文本,就是用最大的黑体字来显示。

图1-1显示了这个页面在浏览器中的效果。

提示:你不需要精通HTML就能进行A 网页编程,虽然它(HTML)是很有用的。

为了快速介绍一下HTML,给大家介绍一个网上的优秀HTML指南。

HTML 2.0 首次引入了一个网页编程的新技术,称为HTML表单。

HT ML表单扩展了HTML的功能,不仅包含了格式化标签,而且包含了窗体小部件或者叫控件。

这些控件包含了普通的功能部件,如下拉列表、文本框和按钮。

下面是一个由HTML表单控件创建的网页。

网页表单允许网页程序设计师设计标准的输入页面。

当用户单击图1-2的提交按钮,所有在输入控件中的数据(在这个例子中是两个复选框)将打包成一个长字符串,接着发送到服务器。

在服务器端,一个客户程序接收和处理这些数据。

令人惊奇的是:这些为HTML表单创建有超过十年之久的控件仍然是你用来创建页面的基础。

不同的是这些程序控件将运行在服务器端。

在过去,当用户单击一个表单页面的按钮时,信息要通过e-mail来发送或者使用在服务器端运行的程序(通过CGI标准)。

今天,你将可以使用更强大、更优雅的平台。

理解的创建原因可以帮助我们了解其他网页开发技术遇到的问题。

在原始的CGI标准下,举个例子,网页服务器必须为每个网页请求建立一个单独的程序实例。

如果这个网页很受人们欢迎(那访问者将很多),那么网页服务器就要经受得起数以百计的独立程序副本,这样最终导致服务器反而因为受欢迎而成为受害者。

为了解决这个问题,微软开发了ISAPI(网络服务程序编程接口),一个高层次的编程模型。

IS API解决了性能问题,但是付出了复杂性的代价。

即使ISAPI开发者是个C+编程老手,他仍然晚上担心到失眠,因为会遇到多线程处理这样让人麻烦的问题。

ISAPI编程是给那些坚强的“夜猫子”,不是给那些懦弱的人。

ISAPI并没有真正消失,取代它的是,微软利用它建立了一个更高级的开发平台,如ASP 和 。

这两种技术都可以使开发者编写动态网页,而不需要担心底层的执行细节。

由于这个原因,这两个平台成功到令人难以置信。

最初的ASP平台吸引了将近一百万的开发人员。

当第一次发布时,作为.NET Framew ork的核心部件受到人们更多关注。

事实上, 1.0已经在数十个大型商业网络中得到应用,虽然它还在最后的测试阶段。

虽然拥有类似的基础,ASP 和有根本的不同。

ASP是基于脚本的编程语言,需要全面理解HTML,而且还要经过一大堆痛苦的编程训练。

而,在另一方面,是面向对象的编程模型,建立网页页面就像建立桌面程序一样容易。

在很多方面,学会比精通ASP要容易,而且功能更加强大。

同时,服务器端的网络发展为从技术的字母形花片汤到广受欢迎的一类编程开发人员开始试着使用嵌入多媒体、JavaScript的小程序、DHTML和Java代码来增强网页的功能。

这些基于客户端的技术不需要通过服务器的处理就能实现。

所有的程序都(从服务器)下载到客户端浏览器,在本地执行。

客户端技术的最大问题就是它们不被所有的浏览器和操作系统完美的支持。

其中的一个原因就是网络开发太受欢迎了,首先是网络程序不需要通过CD安装、下载和其他单调的配置。

取而代之的是,一个网络程序只要能上网的电脑就可以执行了。

但是,一旦开发者使用客户端技术,他们就会遇到一些常见的问题:比如跨浏览器的兼容性。

开发者就不得不在不同的浏览器和操作系统中测试他们的网页,甚至他们还要给用户发布浏览器更新。

换句话说,客户端模型牺牲了网络程序最重要的优良特性。

由于上述原因,被设计为服务器端技术。

所有的代码都在服务器上执行。

当代码执行完毕时,用户就会得到一个普通的HTML页面,这样任何浏览器都可以浏览了。

图1-3显示了服务器端和客户端模型的不同。

这里还有几条原因要避免客户端编程:孤立性:客户端代码无法访问服务器资源。

举个例子,没有一种简单的方式让客户端可以读取一个在服务器上的文件或进行数据库连接。

(至少不会遇到安全性和浏览器兼容性的问题)安全性:最终用户可以查看客户端代码。

一旦有不怀好意的用户理解了程序是怎么工作的,他们就有可能乱来了。

在某些方面,允许你通过服务器端编程结合最佳的客户端编程。

举个例子:控件可以智能侦测客户端浏览器的属性。

如果该浏览器支持JavaScript,那么这些控件将返回一个含有JavaScript的更多功能的页面。

尽管如此,不管浏览器的功能有多强大,你的代码始终在服务器端执行。

状态限制:为了保证最佳性能,网络设计成无状态的协议。

意思就是:一旦页面已经传送给用户,连接就关闭了而且用户指定的信息也被丢弃了。

ASP包括一个ses sion state(会话状态)特性允许程序员来解决这个问题。

使用session state,一个网页程序可以为每一个客户端暂时保存信息(保存在服务器的内存里)。

尽管如此,如果一个网站是放在几个服务器上,session state就无能无力了。

在这种情况下,一个客户要访问B 服务器,而他的会话信息是被A服务器保留的,这样实际上这个会话信息将被丢弃掉。

ASP. NET纠正了这个问题,允许把状态储存在中央仓库,就像一个单独的进程或者一个所有服务器都可以访问的数据库。

通过引进全新的模型解决了上述问题(当然不止这些啦)。

这个模型是基于一个伟大的技术,称之为.NET Framework。

你应该知道的是:.NET Framew ork是几种技术的群集(集合)。

.NET语言:包括C#、(Visual Basic .NET一种面向对象的、现代化的语言(VB 6.0的继任者);这些语言还包括:(服务器端版本的JavaScript,J#(java的兼容产品),还有C++管理扩充。

CLR(公共语言运行库):CLR是执行所有.NET程序和为这些程序提供自动服务的引擎,如安全验证、内存管理和优化等。

.NET Framework类库:类库包含了成千上万个已经预建好的函数,你可以在你的程序中嵌入它们。

这些众多属性有时也被成为一个技术集,如(用来创建数据库程序的技术)和Windows Forms(也是一种技术,用来创建基于桌面的用户界面程序)。

:这是一种主机网页程序和网络服务的引擎,从.NET类库中包含了几乎所有特性。

还包含了网页特有的服务。

Visual Studio:这个可选的开发工具包含了众多提高效率和调试功能的特性。

VS的安装CD(或DVD)包含了完整的.NET Framework,所以你不需要额外下载它。

有趣的是,C#和比C#和Java要相似多了(或者是VB6和)。

虽然语法是不同的,但是C#和都使用.NET类库,也都由CLR支持。

事实上,几乎所有的C#代码块都可以一行一行翻译成的代码块。

当然也有不行的时候(如:C#语言支持一种属性叫调用匿名方法,而不支持)。

但是对绝大部分来说,只要开发者学会了其中一个.NET语言,就可以很快学会另一种。

简而言之,C#和都是一流的,现代的用来开发下一代网络程序的语言。

.NET 1.0引进了一种全新的语言。

尽管如此,.NE T 2.0语言的变化还是细微的。

C# 2005和VB2005都添加了一些新的特性,但是这些语言绝大部分都没有变化。

因此,任何使用C#1.0编写的代码都可以同样的在2.0下运行。

在第二、三章,就会学到C#语法和面向对象编程的基础。

搞定了这些基础,你就可以开始创建简单的网页了。

这样你就会少点困惑,学得更快。

(向一些高级话题进军,如数据库访问和网络服务)CLR(公共语言运行库)只能运行IL代码,这就意味着它根本不知道你的源代码是用哪一个语言编写的,尽管如此,CLR竟然完成了另外一个编译步骤——它接受了IL代码并把它转换成适合当前平台的本机机器语言。

这个步骤在程序启动时发生,而且在代码被真正执行之前。

在程序中,当网络程序正在运行时,这些特定机器文件存储在高速缓存中,所以它们可以被复用(重新使用),以确保最佳性能。

你或许会问.NET为什么不直接编译成机器语言。

原因是:机器代码取决于多个因素,包括CPU。

举个例子,如果你是为一台含有Intel 处理器的电脑而创建的机器代码,那么编译器将能够使用超线程技术来增强你的代码。

这种适用特点机器的版本并不适合在其他电脑中运行,因为你无法保证它们使用同样的处理器。

在VS 2005中,另一个受人欢迎的改变是支持不同的编码模型。

而VS2 003却受那个困扰,VS 2005支持某个范围的不同编码模型,使它成为具有灵活性、通用性我的设计工具。

这就让你可以把HTML标签和事件处理代码放在同一个文件内或者分开存放,而不用委屈的使用VS,这样可以享受有用的特性好处,如代码智能完成。
