3.1 Internet Service FunctionTask 1: Enumerate the Web browsers we often use.Task 2: Write down what did you do with the Internet in English.Task 3: Talk about how to send out an E-mail.Task 4: Explain how to use FTP in your studying.Task 5: Contrasts FTP with the World Wide Web, then speaks out the difference between them.Once your computer enters into a connection with the Internet, you will find that you have walked into the largest repository of information. The two most popular Web browsers are Microsoft Internet Explorer and Netscape Navigator. A Web browser presents data in multimedia on Web pages that use text, graphics, sound and video.The Web pages are created with a formal language called Hypertext Markup Language (HTML). The term hypertext is used to describe an interlinked system of documents in which a user may jump from one document to another in a nonlinear way. Hyperlink makes the Internet easy to navigate. It is an object (word, phrase, or picture) on a Web page that, when clicked, transfers you to a new Web page. The Web page contains an address location known as Uniform Resource Locator (URL). When hypertext pages are mixed with other media, the result is called hypermedia.The following are the important service functions that Internet provides.1. E-mailThe most widely used tool on the Internet is electronic mail or E-mail. E-mail enables you to send messages to America, Australia and so on, no matter how far between individuals. E-mail messages are generally sent from and received by mail servers—computers that are dedicated to processing and directing E-mail. Once a server has received a message it directs it to the specific computer that the E-mail is addressed to. To send E-mail, the process is reversed. As a very convenient and inexpensive way to transmit messages, E-mail has grammatically affected scientific, personal, and business communications. In some cases, E-mail has replaced the telephone for carrying messages.2. File transferFile Transfer Protocol (FTP) is a method of transferring files from one computer to another over the Internet, even if each computer has a different operating system or storage format. FTP is designed to download files or upload files. The ability to upload and download files on it is one of the most valuable features the Internet has to offer. This is especially helpful for those people who rely on computers for various purposes and who may need software drivers and upgrades immediately. Network administrators can rarely wait even a few days to get the necessary drivers that enable their network servers to function again. The Internet can provide these files immediately by using FTP. FTP is a client-server application just like E-mail and Telnet. It requires server software running on a host that can be accessed by client software.3. The World Wide WebThe World Wide Web (WWW), which Hypertext Transfer Protocol (HTTP) works with, is the fastest growing and most widely-used part of the Internet. It provides access to multipleservices and documents as Gopher does but is more ambitious in its method. A jump to other Internet service can be triggered by a mouse click on a “hot-linked” word, image, or icon on the Web pages. One of the main reasons for the extraordinary growth of the Web is the ease in which it allows access to information. One limitation of HTTP is that you can only use it to download files, and not to upload them.4. TelnetTelnet allows an Internet user to connect to a distance computer and use that computer as if he or she were using it directly. To make a connection with a Telnet client, you must select a connection option: “Host Name” and “Terminal Type”. The host name is the IP address (DNS) of the remote computer to which you connect. The terminal type describes the type of terminal emulation that you want the computer to perform.The Internet has many new technologies, such as global chat, video conferencing, free international phone and more. The Internet becomes more and more popular in society in recent years. So we can say that Internet is your PC’s window to the rest of the world.Key Termshypertext 超文本hyperlink 超链接hypermedia 超媒体client-server 客户-服务器mail server 邮件服务器FTP(File Transfer Protocol) 文件传输协议WWW(World Wide Web) 万维网Telnet 远程登录DNS(Domain Name Server) 域名服务器video conferencing 电视会议HTML(hypertext Markup Language) 超文本链接标示语言URL(Uniform Resource Locator) 统一资源定位符IP(Internet Protocol) 互联网协议,网际协议Vocabularyrepository n.仓库,资源丰富的地方nonlinear adj.非线性的dedicate to 用做…,奉献ambitious adj.雄心的,野心的trigger v.引发,引起,触发extraordinary adj.特别的,非常的terminal n.终端emulation n.竞争,效法TrainingI.

Fill in the blanks with proper words.The Web pages are created with a formal language called ___ ___, and __ ____ makes the Internet easy to navigate. The main Internet service functions are ______, ______,______ and ______.3.2 Website DesignTask 1: Finish a website according to the knowledge you have learned, and then describe the process in English.Task 2: Write down the six step tutorial helps you develop a premier website in you own words.Task 3: Discuss the website development in group. Explain how many have you exercised in your course of dynamic website design.Task 4: How many methods have been referred to create balanced page layout in the text? Which method have you often used in your experience? Write down why you have used the method so often.Many people wish they had software to create a flashy website. But creating a great website doesn’t happen at the tips of the fingers; it happens in the depths of the brain. Outst anding websites result from extensive planning. Prior preparation saves time and avoids frustration both during page creation and when updates and additions are required. Based on recommendations by professional web designers, the 6-step design tutorial helps you develop a premier website.Website Design Steps1. Establish an identity and use it consistently on all pagesIt doesn’t mean every page looks the same, but the colors and graphics we use should be consistent throughout the website. Even before knowing the number or type of pages, or a navigation scheme, create a homepage template and three or four sub-page templates using the chosen colors and graphics in combinations that are eye-catching and carrying forth your identity.2. Determine who uses your site and their information needsSuccessful websites know who their customers are and why they visit, and they provide aresponsive and attractive display to those viewers. Customers don’t visit our site because we spend time creating it; customers deserve maximum benefit from the time they allocate to us.3. Create user-friendly navigationOn a well-planned website it’s quick and easy to get to information pages—that’s navigation. Plan navigation before pages are created. Establish a navigation plan now to ensure that viewers quickly get what they need, and that webmasters can quickly insert new pages of content.4. Page layoutTo begin layout, analyze the information to be displayed and decide how it will be most readable. Pick the template that best accommodates that display. As your templates were created, page layout may have been anticipated. There are three methods to create balanced page layout: blockquote margins, tables, and frames. Each method has pros and cons; it can be advantageous to use all three to build a website.5. Focus on textThe best websites pack essential information into well-organized and well-written text. WebPages should not, however, be too heavily texted. Surveys show that web users will not read long paragraphs of information. They prefer concise, bite-sized sections, clearly delineated so they can scan for the information they need. You should write essential content as clearly and concisely as possible with brief topic headers.6. Use graphic images to enhance, not overpowerGraphics are a special challenge for web designers, requiring balance between overuse and skimpiness. A site filled with graphic images can have charm and impact. The secret for effective graphics is to stick to the theme and identity of the website.Website Development1. Interactive Dynamic WebsitesWebsites have grown from static online to become interactive dynamic sites. This is usually achieved by the use of a database, which is linked to the WebPages to serve content on the fly. The creation of sites involves programming skills and is known as website development.2. Real Time UpdatesThis means that sites can be updated in real time. For example a Discount Travel site could show availability and prices of all their available flight packages. When a particular flight is fullybooked the site would show this. Another example of website development would be an auction site that has constantly changing prices in response to bids from auction visitors to the site.3. Database ApplicationsThere are thousands of more applications for database website development and in the near future database driven sites are going to become the norm. This is partly due to the fact that web development sites are growing larger all the time and it is unpractical to update a large site in any other way. The most common databases for website development are Access, for simple databases; SQL, for more complex databases and Oracle, for the largest, most complex jobs.4. Active Server PagesASP (Active Server Pages ) —a programming language based on server side—as the best solution to create and implement dynamic websites is introduced in 1996 by Microsoft. Active Server Pages is an open, compile-free application environment in which you can combine HTML, Scripts and reusable ActiveX server components to create dynamic and powerful Web-based business solutions.Key Termstemplate n.(=templet)样板,模板navigation n.导航webmaster n.站点管理员,网络设计师compile v.编译static adj.静态的dynamic website 动态网站real time update 实时更新database application 数据库应用程序ASP(Active Server Pages) 动态服务器页面Vocabularywebsite n.网站prior adj.优先的,在先的frustration n.挫折,挫败,受挫premier adj.首要的,第一的n.总理homepage n.主页allocate v.分配,分派layout n.布置,安排,规划,设计accommodate v.容纳,适应,供给,供应blockquote margin 块边缘frame n.框架pros and cons 优缺点concise adj.简明的,简洁的delineate v.描绘,叙述,描写auction n.拍卖v.拍卖norm n.标准,规范TrainingI.

Use some words to describe it.3.3 Five Most Common Web Design MistakesTask 1: Design a website everybody and then discuss the mistakes group by group. Then compare with the text write down your own idea about the web design mistakes.Task 2: Combine with the knowledge you have learned explain the function of counters and banners.As you’re designing your new web site,you’ll be tempted with web design ideas that could turn into fatal mistakes. Below are five of the most common mistakes to avoid at all costs...1. Too Many GraphicsHaving too many graphics (particularly large graphics),can cause your site to load entirely too slow, Visitors will get impatient and oftentimes click out of your site—never to return.SOLUTION: When possible save your graphics as GIF files rather than JPEG, Also, reduce your graphic in actual size as much as you can without distorting the graphic or picture.2. CountersA visitor counter or hits counter should not be seen on your site unless you have tremendous traffic. The reason for this is that visitors really don’t want to know which visitor they are, especially if they’re Visitor number four. There’s no benefit to your visitor,nor is there anybenefit to you. The only way showing a counter is advantageous is if you’ve had millions of visitors and wish to display the popularity of your site or would like to attract advertisers with the large numbers.Otherwise, you can use this space for a headline that leads your visitor to another part of your site.SOLUTION: Most web hosts offer web statistics that reveal daily visitors,hits, etc. This feature will let you know how many people are visiting your site without me whole world seeing the information.If you’re just starting out, make sure your web host offers this free service.3. BannersLimit your banners to the bare necessities.Why? Because banners are graphics that can slow loading time and are a turn-off for many surfers on the Internet.For most,“banner” is just another word for“ad” and they avoid clicking on them.SOLUTION: If you do have a banner or two, place the banner at the very top or bottom of your page. Or you could place a small banner in your sidebar. Most people will look at the first picture they see and then start reading below the picture, so any writing or links that are above the banner may remain unnoticed.Also, the banners on your site should be related to your product or service.Remember, everything on your site should work together to benefit your target customer.4. Scattered Web SiteWhen designing your site, make sure it has a pattern that leads your visitor. Get several people (friends or relatives) to visit your site and watch them as they navigate. Notice the places where they stop and links that they click on. Organizing your site to lead visitors is very important whether you’re leading them to buy something or just to click and go to another place in your site.SOLUTION: Make sure t hat graphics don’t get in the way of your lead. If the visitor stops in the middle of the home page to click on a graphic or banner before getting to your sales page, they may never return.5. GeneralizationThe most effective way of selling on the Internet is to personalize your web site to reach your target audience. Many web sites are general and try to reach everybody. The reality is that you can’t be everything to everybody. The business owners who are successful on the web normally have very specific products or services that target a niche market.SOLUTION: Make your site as personal as possible. As you’re writing pretend that you areface 10 face with the customer. Present your web site in such a way that the visitor feels like he just walked into a store in his hometown. Also. stay focused on your target customer (one who would be inte rested in “your” product.)These five mistakes should be avoided at all costs if you want to build an effective and successful web business.Vocabularyfatal adj.致命的,毁灭性的avoid v.避免,消除at all cost 不惜任何代价,无论如何oftentimes adv.时常地distort v.歪曲,扭曲,弄歪counter n.计数器,计算器tremendous adj.巨大的,极大的traffic n.流量,访问量headline n.大字标题host n.主机reveal v.展示,展现,揭示,暴露banner n.旗帜,横幅,标语turn off <口语>令人厌烦的事物sidebar n.边注,其他选项,工具条personalize v.使成私人的,人格化niche market 有利可图的市场TrainingI. Translate the following sentences.1. Having too many graphics (particularly large graphics),can cause your site to load entirely too slow, Visitors will get impatient and oftentimes click out of your site—never to return.2. The only way showing a counter is advantageous is if you've had millions of visitors and wish to display the popularity of your site or would like to attract advertisers with the large numbers.Otherwise, you can use this space for a headline that leads your visitor to another part ofyour site.3.

CHAPTER 3: Attraction 103 self-centered, and vain. On the other hand, she was really hot, so he asked her out anyway. Because she was impressed with his designer clothes and bold style, Rebecca was intrigued by Rasheed, but after a few minutes she thought him a little pushy and arrogant. Still, he had tickets to an expensive concert, so she accepted his invitation to go out on a date.I n your opinion, what does the date—and the future—hold for Rebecca and Rasheed? Why?C HAPTER SUMMARYT he Fundamental Basis of AttractionW e are attracted to people whose presence is rewarding to us.P roximity: Liking Those Near UsW e select our friends, and our enemies, from those around us.C onvenience: Proximity Is Rewarding, Distance Is Costly. Relationships with distant partners are ordinarily less satisfying than they would be if the partners were nearby.F amiliarity: Repeated Contact. In general, familiarity breeds attraction. Even brief, m ere exposure to others usually increases our liking for them.T he Power of Proximity. Close proximity accentuates our feelings about others for better or for worse.P hysical Attractiveness: Liking Those Who Are LovelyO ur Bias for Beauty: “What Is Beautiful Is Good.” We assume that attrac-tive people have other desirable personal characteristics.W ho’s Pretty?Symmetrical faces with average features are especially beautiful. W aist-to-hip ratios of 0.7 are very appealing in women whereas a WHR of 0.9 is attractive in a man if he has money.A n Evolutionary Perspective on Physical Attractiveness. Cross-cultural agreement about beauty, cyclical variations in women’s preferences, and the link between attractiveness and good health are all consistent with the assump-tions of evolutionary psychology.C ulture Counts, Too. Standards of beauty also fluctuate with changing economic and cultural conditions.L ooks Matter. When people first meet, nothing else affects attraction as much as their looks do.104 CHAPTER 3: AttractionT he Interactive Costs and Benefits of Beauty. Physical attractiveness has a larger influence on men’s social lives than on women’s. Attractive people doubt the praise they receive from others, but they’re still happier than unat-tractive people are.M atching in Physical Attractiveness. People tend to pair off with others of similar levels of beauty.R eciprocity: Liking Those Who Like UsP eople are reluctant to risk rejection. Most people calculate others’ overall desirability by multiplying their physical attractiveness by their probability of reciprocal liking. This is consistent with balance theory, which holds that people desire consistency among their thoughts, feelings, and relationships.S imilarity: Liking Those Who Are Like UsB irds of a feather fl ock together. People like those who are similar to them.W hat Kind of Similarity?Happy relationship partners resemble each other in demographic origin, attitudes and values, and personality traits.D o Opposites Attract?Opposites do not attract, but the belief that they do may persist for several reasons. First, matching is a broad process; fame, wealth, health, talent, and looks are all commodities people use to attract oth-ers. Second, it takes time for p erceived similarity to be replaced by a more accu-rate understanding of the attributes we share with others. Misperceptions may persist for some time. Third, people a re also attracted to those who are mildly different from themselves but similar to their ideal selves. People also tend to become more similar over time, and some types of similarity are more impor-tant than others. Finally, we may occasionally appreciate behavior from a part-ner that differs from our own but that complements our actions and helps us to reach our goals.W hy Is Similarity Attractive? Similarity in others is reassuring. We also judge similar others positively and assume they like us.B arriers: Liking the Ones We Cannot HaveT he theory of psychological r eactance suggests that people strive to restore lost freedom. The theory explains the R omeo and Juliet effect as well as the ten-dency for potential partners to seem more attractive at bars’ closing time.S o, What Do Men and Women Want?P eople evaluate potential partners with regard to (a) warmth and loyalty, (b) attractiveness and vitality, and (c) status and resources. For lasting romances, women want men who are warm and kind and who are not poor, and men want women who are warm and kind and who are not unattractive. Thus, everybody wants intimate partners who are amiable, agreeable, and loving.C H A P T E R4S ocial CognitionF i rst I m pressions ( a nd B e yond )◆The P o wer of P e rceptions ◆IdealizingOur Partners ◆Attributional Processes ◆Memories ◆Relationship Beliefs ◆Expectations ◆Self-Perceptions ◆I m pression M a nagement ◆Strategies of Impression Management ◆ImpressionManagement in Close Relationships ◆S o, J u st H o w W e ll D o W eK n ow O u r P a rtners? ◆Knowledge ◆Motivation ◆Partner Legibility ◆Perceiver Ability ◆Threatening Perceptions ◆Perceiver Influence ◆Summary ◆F o r Y o ur C o nsideration ◆C h apter S u mmary I m agine that you’re home in bed, sick with a killer flu, and your lover doesn’t call you during the day to see how you’re doing. You’re disappointed. Why didn’t your partner call? Does he or she not love you enough? Is this just another frustrating example of his or her self-centered lack of compassion? Or is it more likely that your loving, considerate partner didn’t want to risk waking you from a nap? There are several possible explanations, and you can choose a forgiving rationale, a blaming one, or something in between. And importantly, the choice may really be up to you; the facts of the case may allow several dif-ferent interpretations. But whatever you decide, your judgments are likely to be consequential. At the end of the day, your perceptions will have either sus-tained or undermined the happiness of your relationship.W e’ll focus on judgments like these in this chapter on s ocial cognition,a term that refers generally to the processes of perception and judgment with which we make sense of our social worlds (Moskowitz, 2005). Our primary con-cern will be with the way we t hink about our relationships. We’ll explore how our judgments of our partners and their behavior set the stage for the events that follow. We’ll consider our own efforts to influence and control what our partners think of us. And we’ll ponder just how well two people are likely to know each other, even in an intimate relationship. Throughout the chapter, I’ll emphasize the fact that our perceptions and interpretations of our partnerships are of enormous importance: What we think helps to determine what we f eel, and then how we a ct.This wouldn’t be a problem if our judgments were always correct. However, there are usually a variety of reasonable ways to interpret an event (as my opening example suggests), and we can make mistakes even when we’re confident that we have arrived at the truth. Indeed, some of those mistakes may begin the moment we meet someone, as studies of first impres-sions reveal.106 CHAPTER 4: Social CognitionF IRST IMPRESSIONS (AND BEYOND)F irst impressions matter. The judgments we form of others after a brief first meeting often have enormous staying power, with our initial perceptions con-tinuing to be influential months later. This fact may be obvious if we dislike someone so much after an initial interaction that we avoid any further contact with him or her (Denrell, 2005); in such cases, our first impressions are the only impressions we ever get. However, first impressions continue to be influential even when we do see more of a new acquaintance. When researchers formally arranged get-acquainted conversations between new classmates, the initial impressions the students formed continued to influence their feelings about each other 9 weeks later (Sunnafrank & Ramirez, 2004).C onceivably, some first impressions may last because they are discern-ing and correct. Sometimes it doesn’t take us long to accurately decide who’s nice and who’s not, and if we’re right, we may never need to revise our initial perceptions. On the other hand, first impressions can be remarkably persis-tent even when they’re erroneous (Harris & Garris, 2008). Right or wrong, first impressions linger, and that’s why they matter so much. Let’s consider how they operate.W e start judging people from the moment we meet them. And by “moment,” I mean the first twenty-fifth of a second. That’s all it takes—only 39 milliseconds 1—for us to determine whether a stranger’s face looks angry (Bar et al., 2006). After more patient deliberation lasting one-tenth of a second, 2 we have formed judgments of a stranger’s attractiveness, likeability, and trust-worthiness that are the same as those we hold after a minute’s careful inspec-tion of the person’s face (Willis & Todorov, 2006). Then, after watching the stranger chat with someone of the other sex for only 5 seconds, we’ve already decided how extraverted, conscientious, and intelligent he or she is (Carney et al., 2007). We jump to conclusions very, very quickly.O ur snap judgments are influenced by the fact that everyone we meet fits some category of people about whom we already hold stereotyped first impres-sions. This may sound like a daring assertion, but it really isn’t. Think about it: Everyone is either male or female, and (as we saw in chapter 1), gender-role stereotypes lead us to expect different behavior from men and women. Fur-thermore, at a glance, we can tell whether someone is beautiful or plain, and (as we saw in chapter 3), we assume that pretty people are likeable people. Dozens of other distinctions may come into play: young/old, black/white, pierced/unpierced, country/urban, and many more. The specifics of these ste-reotypes may vary from one perceiver to the next, but they operate similarly in anyone: Stereotypes supply us with preconceptions about what people are like ( F reeman et al., 2010). The judgments that result are often quite incorrect 1 A millisecond is a thousandth of a second. So, after 39 milliseconds have passed, there’s still 96.1 percent of a second yet to come before one full second has passed.2 I’m not kidding, but I am being playful.CHAPTER 4: Social Cognition 107 (Olivola & Todorov, 2010), but they’re hard to avoid: Stereotypes influence us automatically, even when we are unaware of using them (Devine & M o nteith, 1999). So, some initial feelings about others may spring up unbidden even when we want to be impartial and open minded.T hen, if we do interact with someone, we continue jumping to conclusions as our interaction unfolds. Please take a moment—seriously, take your time and read the next line slowly—and consider someone who ise nvious, stubborn, critical, impulsive, industrious, and intelligent.W ould you want this person as a co-worker? Probably not much. Now, please take another moment to size up someone else who isi ntelligent, industrious, impulsive, critical, stubborn, and envious.M ore impressive, yes? This person isn’t perfect, but he or she seems competent and ambitious. The point, of course, is that the two descriptions offer the sameWhen we meet others for the first time, we rarely form impressions of them in an unbi-ased, even-handed manner. Instead, various stereotypes and primacy effects influence our interpretations of the behavior we observe.。

chapter 3 阅读模式

chapter 3   阅读模式

• 自上而下阅读模式是古德曼在六十年代末提出来的。他认为,阅 读过程并非是一个精确的知觉过程,而是一个选择的过程,即在 阅读者预测的基础上运用那些可能得到的最少的、从知觉中选择 而来的语言线索。一旦这些选择而来的信息被加工,则形成“暂 时决定”。而这些“暂时决定”在继续阅读中会加以证实、拒绝 或进一步提炼,直到阅读者理解阅读材料,阅读过程便告完成。 这种模式可以表示为: 经验、语感、期待——选择部分材料——意义
• 此外,他强调阅读者认知系统依赖于已有的语言知识和社会经历。 在阅读过程中,充分发挥语言知识和社会经历的作用,以此来推 动对书面文字的理解。 • 古德曼认为,自上而下阅读模式的主要步骤是: • (1)扫瞄和注视。从左到右对文字符号进行扫瞄,并对某些部分 进行注视。 • (2)选择线索,形成表象。选择那些将成为知觉表象的信息,结 合对材料的预测信息(线索)形成一种知觉表象。
• Reading has traditionally been the most important source of information in the learning situation. The traditional reading advocates using bottom-up model---a kind of passive decoding model. That is to say , the reader only need to read word by word, it will be very easy to get the whole meaning for them. With the development of applied-linguistics and psychological linguistics, the researchers found that reading is not a process of passive decoding model, but a process of active” guessconfirm”. ( Goodman, 1971:135). That is top-down model. After that , the artificial, intelligence expert D.E Rumelhart said reading was a process that the bottom-up model and the top-down model interact together and at the same time processes word information. It was called interact model.

交互式计算机图形学1-7章课后题答案

交互式计算机图形学1-7章课后题答案

Angel: Interactive Computer Graphics, Fifth Edition Chapter 1 SolutionsThe main advantage of the pipeline is that each primitive can be processed independently. Not only does this architecture lead to fast performance, it reduces memory requirements because we need not keep all objects available. The main disadvantage is that we cannot handle most global effects such as shadows, reflections, and blending in a physically correct manner.We derive this algorithm later in Chapter 6. First, we can form the tetrahedron by finding four equally spaced points on a unit sphere centeredat the origin. One approach is to start with one point on the z axis (0, 0, 1). We then can place the other three points in a plane of constant z.One of these three points can be placed on the y axis. To satisfy the requirement that the points be equidistant, the point must be at(0, 2p2/3,−1/3). The other two can be found by symmetry to be at(−p6/3,−p2/3,−1/3) and (p6/3,−p2/3,−1/3).We can subdivide each face of the tetrahedron into four equilateral triangles by bisecting the sides and connecting the bisectors. However, thebisectors of the sides are not on the unit circle so we must push these points out to the unit circle by scaling the values. We can continue this process recursively on each of the triangles created by the bisection process.In Exercise , we saw that we could intersect the line of which the line segment is part independently against each of the sides of the window. We could do this process iteratively, each time shortening the line segmentif it intersects one side of the window.In a one–point perspective, two faces of the cube is parallel to the projection plane, while in a two–point perspective only the edges of the cube in one direction are parallel to the projection. In the general case of athree–point perspective there are three vanishing points and none of the edges of the cube are parallel to the projection plane.Each frame for a 480 x 640 pixel video display contains only about 300k pixels whereas the 2000 x 3000 pixel movie frame has 6M pixels, or about 18 times as many as the video display. Thus, it can take 18 times asmuch time to render each frame if there is a lot of pixel-level calculations.There are single beam CRTs. One scheme is to arrange the phosphorsin vertical stripes (red, green, blue, red, green, ....). The major difficulty isthat the beam must change very rapidly, approximately three times as fast a each beam in a three beam system. The electronics in such a system the electronic components must also be much faster (and more expensive).Chapter 2 SolutionsWe can solve this problem separately in the x and y directions. The transformation is linear, that is xs = ax + b, ys = cy + d. We must maintain proportions, so that xs in the same relative position in the viewport as x is in the window, hencex − xminxmax − xmin=xs − uw,xs = u + wx − xminxmax − xmin.Likewiseys = v + hx − xminymax − ymin.Most practical tests work on a line by line basis. Usually we usescanlines, each of which corresponds to a row of pixels in the frame buffer.If we compute the intersections of the edges of the polygon with a line passing through it, these intersections can be ordered. The first intersection begins a set of points inside the polygon. The second intersection leaves the polygon, the third reenters and so on.There are two fundamental approaches: vertex lists and edge lists. With vertex lists we store the vertex locations in an array. The mesh is represented as a list of interior polygons (those polygons with no other polygons inside them). Each interior polygon is represented as an array ofpointers into the vertex array. To draw the mesh, we traverse the list ofinterior polygons, drawing each polygon.One disadvantage of the vertex list is that if we wish to draw the edges inthe mesh, by rendering each polygon shared edges are drawn twice. We can avoid this problem by forming an edge list or edge array, each element is a pair of pointers to vertices in the vertex array. Thus, we can draw eachedge once by simply traversing the edge list. However, the simple edge listhas no information on polygons and thus if we want to render the mesh in some other way such as by filling interior polygons we must add something to this data structure that gives information as to which edges form each polygon.A flexible mesh representation would consist of an edge list, a vertex listand a polygon list with pointers so we could know which edges belong to which polygons and which polygons share a given vertex.The Maxwell triangle corresponds to the triangle that connects the red, green, and blue vertices in the color cube.Consider the lines defined by the sides of the polygon. We can assign a direction for each of these lines by traversing the vertices in a counter-clockwise order. One very simple test is obtained by noting that any point inside the object is on the left of each of these lines. Thus, if wesubstitute the point into the equation for each of the lines (ax+by+c), weshould always get the same sign.There are eight vertices and thus 256 = 28 possible black/white colorings. If we remove symmetries (black/white and rotational) there are 14 unique cases. See Angel, Interactive Computer Graphics (Third Edition) or the paper by Lorensen and Kline in the references.Chapter 3 SolutionsThe general problem is how to describe a set of characters that might have thickness, curvature, and holes (such as in the letters a and q). Suppose that we consider a simple example where each character can be approximated by a sequence of line segments. One possibility is to use amove/line system where 0 is a move and 1 a line. Then a character can be described by a sequence of the form (x0, y0, b0), (x1, y1, b1), (x2, y2, b2), .....where bi is a 0 or 1. This approach is used in the example in the OpenGL Programming Guide. A more elaborate font can be developed by using polygons instead of line segments.There are a couple of potential problems. One is that the application program can map different points in object coordinates to the same point in screen coordinates. Second, a given position on the screen when transformed back into object coordinates may lie outside the user’s window.Each scan is allocated 1/60 second. For a given scan we have to take 10% of the time for the vertical retrace which means that we start to draw scan line n at .9n/(60*1024) seconds from the beginning of the refresh. But allocating 10% of this time for the horizontal retrace we are at pixel mon this line at time .81nm/(60*1024).When the display is changing, primitives that move or are removed from the display will leave a trace or motion blur on the display as the phosphors persist. Long persistence phosphors have been used in text only displays where motion blur is less of a problem and the long persistence gives a very stable flicker-free image.Chapter 4 SolutionsIf the scaling matrix is uniform thenRS = RS(α, α, α) = αR = SRConsider R x(θ), if we multiply and use the standard trigonometric identities for the sine and cosine of the sum of two angles, we findR x(θ)R x(φ) = R x(θ + φ)By simply multiplying the matrices we findT(x1, y1, z1)T(x2, y2, z2) = T(x1 + x2, y1 + y2, z1 + z2)There are 12 degrees of freedom in the three–dimensional affine transformation. Consider a point p = [x, y, z, 1]T that is transformed top_ = [x_y_, z_, 1]T by the matrix M. Hence we have the relationshipp_ = Mp where M has 12 unknown coefficients but p and p_ are known. Thus we have 3 equations in 12 unknowns (the fourth equation is simply the identity 1=1). If we have 4 such pairs of points we will have 12 equations in 12 unknowns which could be solved for the elements of M. Thus if we know how a quadrilateral is transformed we can determine the affine transformation.In two dimensions, there are 6 degrees of freedom in M but p and p_ have only x and y components. Hence if we know 3 points both before and after transformation, we will have 6 equations in 6 unknowns and thus in two dimensions if we know how a triangle is transformed we can determine the affine transformation.It is easy to show by simply multiplying the matrices that the concatenation of two rotations yields a rotation and that the concatenationof two translations yields a translation. If we look at the product of arotation and a translation, we find that the left three columns of RT are the left three columns of R and the right column of RT is the right column of the translation matrix. If we now consider RTR_ where R_ is a rotation matrix, the left three columns are exactly the same as the left three columns of RR_ and the and right column still has 1 as its bottom element. Thus, the form is the same as RT with an altered rotation (which is the concatenation of the two rotations) and an altered translation. Inductively, we can see that any further concatenations with rotations andtranslations do not alter this form.If we do a translation by -h we convert the problem to reflection about a line passing through the origin. From m we can find an angle by which we can rotate so the line is aligned with either the x or y axis. Now reflect about the x or y axis. Finally we undo the rotation and translation so thesequence is of the form T−1R−1SRT.The most sensible place to put the shear is second so that the instance transformation becomes I = TRHS. We can see that this order makes sense if we consider a cube centered at the origin whose sides are aligned with the axes. The scale gives us the desired size and proportions. The shear then converts the right parallelepiped to a general parallelepiped. Finally we can orient this parallelepiped with a rotation and place it wheredesired with a translation. Note that the order I = TRSH will work too. R = R z(θz)R y(θy)R x(θx) =⎡⎡⎡⎡⎡cos θy cos θz cos θz sin θx sin θy −cos θx sin θz cos θx cos θz sin θy + sin θx sin θz 0cos θy sin θz cos θx cos θz + sin θx sin θy sin θz −cos θz sin θx + cos θx sin θy sin θz 0−sin θy cos θy sin θx cos θx cos θy 00 0 0 1⎡⎡⎡⎡⎡One test is to use the first three vertices to find the equation of the plane ax + by + cz + d = 0. Although there are four coefficients in the equation only three are independent so we can select one arbitrarily or normalize so that a2 + b2 + c2 = 1. Then we can successively evaluate ax + bc + cz + d for the other vertices. A vertex will be on the plane if weevaluate to zero. An equivalent test is to form the matrix⎡⎡⎡⎡⎡1 1 1 1x1 x2 x3 x4y1 y2 y3 y4z1 z2 z3 z4⎡⎡⎡⎡⎡for each i = 4, ... If the determinant of this matrix is zero the ith vertex isin the plane determined by the first three.Although we will have the same number of degrees of freedom in the objects we produce, the class of objects will be very different. For exampleif we rotate a square before we apply a nonuniform scale, we will shear thesquare, something we cannot do if we scale then rotate.The vector a = u × v is orthogonal to u and v. The vector b = u × a isorthogonal to u and a. Hence, u, a and b form an orthogonal coordinate system.Using r = cos θ2+ sin θ2v, with θ = 90 and v = (1, 0, 0), we find forrotation about the x-axisr =√22(1, 1, 0, 0).Likewise, for rotation about the y axisr =√22(1, 0, 1, 0).Possible reasons include (1) object-oriented systems are slower, (2) users are often comfortable working in world coordinates withhigher-levelobjects and do not need the flexibility offered by a coordinate-free approach, (3) even a system that provides scalars, vectors, and points would have to have an underlying frame to use for the implementation.Chapter 5 SolutionsEclipses (both solar and lunar) are good examples of the projection ofan object (the moon or the earth) onto a nonplanar surface. Any time a shadow is created on curved surface, there is a nonplanar projection. All the maps in an atlas are examples of the use of curved projectors. If the projectors were not curved we could not project the entire surface of a spherical object (the Earth) onto a rectangle.Suppose that we want the view of the Earth rotating about the sun. Before we draw the earth, we must rotate the Earth which is a rotation about the y axis. Next we translate the Earth away from the origin. Finally we do another rotation about the y axis to position the Earth in itsdesired location along its orbit. There are a number of interesting variantsof this problem such as the view from the Earth of the rest of the solar system.Yes. Any sequence of rotations is equivalent to a single rotation about a suitably chosen axis. One way to compute this rotation matrix is to form the matrix by sequence of simple rotations, such asR = RxRyRz.The desired axis is an eigenvector of this matrix.The result follows from the transformation being affine. We can also take a direct approach. Consider the line determined by the points(x1, y1, z1) and (x2, y2, z2). Any point along can be written parametricallyas (_x1 + (1 −_)x2, _y1 + (1 −_)y2, _z1 + (1 −_)z2). Consider the simple projection of this point 1d(_z1+(1−_)z2) (_x1 + (1 − _)x2, _y1 + (1 − _)y2)which is of the form f(_)(_x1 + (1 − _)x2, _y1 + (1 − _)y2). This form describes a line because the slope is constant. Note that the function f(_)implies that we trace out the line at a nonlinear rate as _ increases from 0to 1.The specification used in many graphics text is of the angles the projector makes with x,z and y, z planes, the angles defined by the projection of a projector by a top view and a side view.Another approach is to specify the foreshortening of one or two sides of acube aligned with the axes.The CORE system used this approach. Retained objects were kept indistorted form. Any transformation to any object that was defined with other than an orthographic view transformed the distorted object and the orthographic projection of the transformed distorted object was incorrect.If we use _ = _ = 45, we obtain the projection matrixP =266641 0 −1 00 1 −1 00 0 0 00 0 0 137775All the points on the projection of the point , z) in the direction dx, dy, dz) are of the form (x + _dx, y + _dy, z + _dz). Thus the shadow ofthe point (x, y, z) is found by determining the _ for which the line intersects the plane, that isaxs + bys + czs = dSubstituting and solving, we find_ =d − ax − by − czadx + bdy + cdz.However, what we want is a projection matrix, Using this value of _ we findxs = z + _dx =x(bdy + cdx) − dx(d − by − cz)adx + bdy + cdzwith similar equations for ys and zs. These results can be computed by multiplying the homogeneous coordinate point (x, y, z, 1) by the projectionmatrixM =26664bdy + cdz −bdx −cdx −ddx−ady adx + cdz −cdy −ddy−adz −bdz adx + bdy −ddz0 0 0 adx + bdy + cdz37775.Suppose that the average of the two eye positions is at (x, y, z) and the viewer is looking at the origin. We could form the images using the LookAt function twice, that isgluLookAt(x-dx/2, y, z, 0, 0, 0, 0, 1, 0);/* draw scene here *//* swap buffers and clear */gluLookAt(x+dx/2, y, z, 0, 0, 0, 0, 1, 0);/* draw scene again *//* swap buffers and clear */Chapter 6 SolutionsPoint sources produce a very harsh lighting. Such images are characterized by abrupt transitions between light and dark. The ambient light in a real scene is dependent on both the lights on the scene and thereflectivity properties of the objects in the scene, something that cannot becomputed correctly with OpenGL. The Phong reflection term is not physically correct; the reflection term in the modified Phong model is evenfurther from being physically correct.If we were to take into account a light source being obscured by an object, we would have to have all polygons available so as to test for thiscondition. Such a global calculation is incompatible with the pipeline model that assumes we can shade each polygon independently of all other polygons as it flows through the pipeline.Materials absorb light from sources. Thus, a surface that appears red under white light appears so because the surface absorbs all wavelengths oflight except in the red range—a subtractive process. To be compatible withsuch a model, we should use surface absorbtion constants that define the materials for cyan, magenta and yellow, rather than red, green and blue.Let ψ be the angle between the normal and the halfway vector, φ be the angle between the viewer and the reflection angle, and θ be the anglebetween the normal and the light source. If all the vectors lie in the sameplane, the angle between the light source and the viewer can be computer either as φ + 2θ or as 2(θ + ψ). Setting the two equal, we find φ = 2ψ. Ifthe vectors are not coplanar then φ < 2ψ.Without loss of generality, we can consider the problem in two dimensions. Suppose that the first material has a velocity of light of v1 andthe second material has a light velocity of v2. Furthermore, assume that the axis y = 0 separates the two materials.Place a point light source at (0, h) where h > 0 and a viewer at (x, y) where y < 0. Light will travel in a straight line from the source to a point(t, 0) where it will leave the first material and enter the second. It willthen travel from this point in a straight line to (x, y). We must find the tthat minimizes the time travelled.Using some simple trigonometry, we find the line from the source to (t, 0)has length l1 = √h2 + t2 and the line from there to the viewer has length 1l2 = _y2 + (x − t)2. The total time light travels is thus l1v1 + l2v2 .Minimizing over t gives desired result when we note the two desired sines are sin θ1 = h√h2+t2 and sin θ2 = −y √(y2+(x−t)2 .Shading requires that when we transform normals and points, we maintain the angle between them or equivalently have the dot productp ·v = p_ ·v_ when p_ = Mp and n_ = Mp. If M T M is an identity matrix angles are preserved. Such a matrix (M−1 = M T ) is called orthogonal. Rotations and translations are orthogonal but scaling and shear are not.Probably the easiest approach to this problem is to rotate the given plane to plane z = 0 and rotate the light source and objects in the same way. Now we have the same problem we have solved and can rotate everything back at the end.A global rendering approach would generate all shadows correctly. Ina global renderer, as each point is shaded, a calculation is done to see which light sources shine on it. The projection approach assumes that we can project each polygon onto all other polygons. If the shadow of a given polygon projects onto multiple polygons, we could not compute these shadow polygons very easily. In addition, we have not accounted for the different shades we might see if there were intersecting shadows from multiple light sources.Chapter 7 SolutionsFirst, consider the problem in two dimensions. We are looking for an _ and _ such that both parametric equations yield the same point, that is x(_) = (1 − _)x1 + _x2 = (1 − _)x3 + _x4,y(_) = (1 − _)y1 + _y2 = (1 − _)y3 + _y4.These are two equations in the two unknowns _ and _ and, as long as the line segments are not parallel (a condition that will lead to a division byzero), we can solve for _ _. If both these values are between 0 and 1, thesegments intersect.If the equations are in 3D, we can solve two of them for the _ and _ where x and y meet. If when we use these values of the parameters in the two equations for z, the segments intersect if we get the same z from both equations.If we clip a convex region against a convex region, we produce the intersection of the two regions, that is the set of all points in both regions,which is a convex set and describes a convex region. To see this, consider any two points in the intersection. The line segment connecting them must be in both sets and therefore the intersection is convex.See Problem . Nonuniform scaling will not preserve the anglebetween the normal and other vectors.Note that we could use OpenGL to, produce a hidden line removed image by using the z buffer and drawing polygons with edges and interiors the same color as the background. But of course, this method was not used in pre–raster systems.Hidden–line removal algorithms work in object space, usually with either polygons or polyhedra. Back–facing polygons can be eliminated. In general, edges are intersected with polygons to determine any visible parts.Good algorithms (see Foley or Rogers) use various coherence strategies tominimize the number of intersections.The O(k) was based upon computing the intersection of rays with the planes containing the k polygons. We did not consider the cost of filling thepolygons, which can be a large part of the rendering time. If we consider ascene which is viewed from a given point there will be some percentage of1the area of the screen that is filled with polygons. As we move the viewer closer to the objects, fewer polygons will appear on the screen but each will occupy a larger area on the screen, thus leaving the area of the screen that is filled approximately the same. Thus the rendering time will be about the same even though there are fewer polygons displayed.There are a number of ways we can attempt to get O(k log k) performance. One is to use a better sorting algorithm for the depth sort. Other strategies are based on divide and conquer such a binary spatial partitioning.If we consider a ray tracer that only casts rays to the first intersection and does not compute shadow rays, reflected or transmitted rays, then the image produced using a Phong model at the point of intersection will be the same image as produced by our pipeline renderer. This approach is sometimes called ray casting and is used in volume rendering and CSG. However, the data are processed in a different order from the pipeline renderer. The ray tracer works ray by ray while the pipeline renderer works object by object.Consider a circle centered at the origin: x2 + y2 = r2. If we know that a point (x, y) is on the curve than, we also know (−x, y), (x,−y), (−x,−y), (y, x), (−y, x), (y,−x), and (−y,−x) are also on the curve. This observation is known as the eight–fold symmetry of the circle. Consequently, we need only generate 1/8 of the circle, a 45 degree wedge, and can obtain the rest by copying this part using the symmetries. If we consider the 45 degree wedge starting at the bottom, the slope of thiscurve starts at 0 and goes to 1, precisely the conditions used for Bresenham’s line algorithm. The tests are a bit more complex and we have to account for the possibility the slope will be one but the approach is thesame as for line generation.Flood fill should work with arbitrary closed areas. In practice, we can get into trouble at corners if the edges are not clearly defined. Such can bethe case with scanned images.Note that if we fill by scan lines vertical edges are not a problem. Probably the best way to handle the problem is to avoid it completely by never allowing vertices to be on scan lines. OpenGL does this by having vertices placed halfway between scan lines. Other systems jitter the y value of any vertex where it is an integer.Although each pixel uses five rays, the total number of rays has only doubled, . consider a second grid that is offset one half pixel in both thex and y directions.A mathematical answer can be investigated using the notion of reconstruction of a function from its samples (see Chapter 8). However, avery easy to see by simply drawing bitmap characters that small pixels lead to very unreadable characters. A readable character should have some overlap of the pixels.We want k levels between Imin and Imax that are distributed exponentially. Then I0 = Imin, I1 = Iminr,I2 = Iminr2, ..., Ik−1 = Imax = Iminrk−1. We can solve the last equation forthe desired r = ( ImaxImin)1k−1If there are very few levels, we cannot display a gradual change in brightness. Instead the viewer will see steps of intensity. A simple rule ofthumb is that we need enough gray levels so that a change of one step is not visible. We can mitigate the problem by adding one bit of random noise to the least significant bit of a pixel. Thus if we have 3 bits (8 levels),the third bit will be noise. The effect of the noise will be to break up regions of almost constant intensity so the user will not be able to see astep because it will be masked by the noise. In a statistical sense the jittered image is a noisy (degraded) version of the original but in a visualsense it appears better.。

How to effectively implement curriculum standards and promote teacher professionalization is the key to the realization of curriculum teaching design. The implementation of curriculum standards has always been put in a prominent position in the curriculum reform research of all countries in the world. How to inspire teachers to think about the implementation process of curriculum standards "like experts" as a whole [1], pay attention to students' learning and growth, and form a good teacher-student interaction has become a hot research issue for educators.2 Research Status(1) Research status abroadForeign scholars pay attention to the study of the interaction between teachers and curriculum, and the representative researchers are Remilard, Drake, etc. They are mainly based on teachers' empirical research to understand the interaction between teachers and curriculum, and use this as an analytical framework to solve the problem of teachers' implementation of curriculum standards. They regard the development of theoretical models as an important part of the implementation of curriculum standards, and the number of models constructed is complex. From the perspective of research, the model can be divided into two categories. One is the model of teachers' curriculumTheory and Practice of Science and Technology implementation, such as the famous "Concern-based adoption model (CBAM)"; The other is the interactive model for the implementation of curriculum standards, such as the curriculum hierarchy theory created by Goodlad in the early stage, and the "teacher student content" interactive model developed by Anderson on the basis of this theory.(2) Domestic research statusThe research in China is relatively late. The research on teachers' implementation of curriculum standards mainly focuses on the implementation level, influencing factors and effectiveness. It is difficult to explore the development context of the implementation of curriculum standards, and the theoretical depth is not enough. Although the theoretical research on the implementation of curriculum standards by teachers has been continuing in recent years, it is still in the exploration period, and there is no systematic theory of curriculum implementation. Some domestic scholars equate the implementation of curriculum standards with teaching, and "curriculum" is regarded as teaching materials. The implementation of curriculum standards is to implement the content of teaching materials; Another part of scholars believe that the implementation of curriculum standards is the process of putting innovative curriculum plans into practice [2].3 Research IdeasBy comparing the research on the implementation of curriculum standards by teachers at home and abroad, it is found that there are some typical models for the implementation of curriculum standards by foreign teachers, and they have developed in depth; However, in China, there are either speculative discussions or direct practical explorations, and there are few theoretical systems for teachers to implement curriculum standards. In view of this, the research idea of this paper is to reconstruct the theoretical analysis framework of teachers' implementation of curriculum standards through the theoretical analysis of foreign typical models, and on this basis, summarize the key issues of teachers' implementation of curriculum standards and design a suitable curriculum standard implementation model, and take the implementation of Java Programming curriculum standards as an example to verify the rationality of the model, At the same time, the consistency of teaching evaluation in the implementation of curriculum standards by teachers is analyzed, and thespecific ideas are shown in Figure 1.Figure 1 Research ideas 119Guohua Xiong 1204 Construction of Interactive Model for Curriculum Standard Implementation (1) Concept of interactive teaching modeThe literature [3]believes that the interactive teaching mode refers to the teaching principle of "students as the main body and teachers as the leading role", which focuses on heuristic teaching and allows students and teachers to participate in the teaching and learning of the course. Literature [4] believes that it is a teaching structure model aimed at cultivating students' independent consciousness and innovation ability, and at "making students love, learn and be good at learning". This paper believes that the interactive teaching mode refers to the teaching mode that, under the guidance of the teaching ideology of "students as the main body, teachers as the leading, and training projects as the main line", around the training projects, interactive teaching methods, supplemented by heuristic methods, let teachers and students participate in the bilateral activities of training project teaching and learning, so as to achieve the goal of cultivating students' innovative spirit and improving practical ability.(2) Relevant theoretical basisAt present, the relevant theories of interactive teaching research mainly focus on constructivism and humanism.Constructivism is one of the most influential educational concepts in the world today. It puts forward a series of new explanations for learning and teaching. It believes that learning is carried out under specific social and cultural background and specific learning environment conditions. When designing practical projects, combining the actual situation of real life is conducive to stimulating students' interest and overcoming the abstraction of learning content To enable students to fully use their knowledge and experience in their cognitive structure, give play to their association and imagination, and promote the effective transfer of students' knowledge [5] [6]. The essence of constructivism is to analyze the nature of cognitive activities and put forward a new understanding of the construction process of learning. Constructivism regards students as the subject and center of the teaching process, attaches importance to the role of students' existing knowledge and experience and psychological structure, attaches importance to the subjective initiative of students' learning process, emphasizes the social and situational nature of students' learning, and believes that teachers should play the role of organizers, helpers and promoters in the teaching process, reflecting the student-oriented teaching concept.Humanism education theory mainly emphasizes the teaching goal view of knowing and unifying, the meaningful free learning view and the student-centered teaching view. Its emphasis is not on the teaching results but on the teaching process, emphasizing the development of students' potential, personality and creativity in the process; What we pay attention to is not the teaching content but the teaching method. In the teaching method, we advocate student-centered, everything for the development of students, and let students choose and discover themselves.(3) Curriculum standard interactive model designSince the teaching of the curriculum follows the corresponding curriculum standards, a better interactive curriculum standard is, to a certain extent, the prerequisite for achieving high-quality curriculum interaction. For another course, from the beginning to the end of the course assessment, the interaction between teachers and students is permeated in the whole teaching process, so we divide the design of interactive curriculum standards into three stages.The first stage is to interact before class and formulate curriculum standards. Before each class,Theory and Practice of Science and Technology the teacher requires the students to preview. Before class, the teacher should explain the teaching objectives, key and difficult points of the course, relevant requirements of practical training and scoring standards to the students. Then, through questionnaires, group discussions, network tool interaction and other methods, master the students' preview situation and basic needs for the course content, and carry out pre-class learning situation analysis based on this, and then modify or redesign in combination with the original curriculum standard to develop a new curriculum standard. Take part of the contents of Chapter 2 Java Programming Basics of Java Programming for example, as shown in Table 1. Since students have learned C Content Language Programming before learning this course, they use the form of pre-class questionnaire to achieve the purpose of interaction. This can clarify what content students can learn by themselves, what content needs to be taught and what kind of teaching method students can accept more easily. Based on this, the curriculum standard of this course can be preliminarily designed.The second stage is interaction in class and adjustment of curriculum standards. During the course of teaching according to the preliminarily designed curriculum standard, analyze whether the students' mastery of knowledge is consistent with the pre-class analysis according to the students' actual training completion and the students' performance in the discussion link. During the course of teaching, students may also put forward some new questions. At this time, the teacher should make a good record and analysis of the learning situation in class, and modify the preliminarily implemented curriculum standard after class according to the analysis. Java Program Design is a practical course, which uses students to achieve the organic integration of theoretical knowledge and practical skills. The course selection is based on project-based teaching. In class, teachers and students jointly discuss the needs analysis of the project. The key technology realization is explained by teachers in the way of theoretical teaching and practical demonstration, and then by students on the computer, To reflect the student-centered concept, students can also design and complete independently.The third stage is after-class interaction and optimization of curriculum standards. After class, teachers should not only organize students to investigate the teaching satisfaction of this class, but also ask students to put forward good practices and problems that need to be improved, and analyze students' mastery of the knowledge of this class according to the completion of homework after class, so as to further optimize the curriculum standards of this class.Through the above theoretical analysis, the designed interactive model for the implementation of curriculum standards is shown in Figure 2.Table 1 Analysis of basic knowledge points of Java programmingKnowledge PointsBasic format of Java programComments in JavaIdentifier in JavaKeywords in JavaConstants in JavaDefinition of variablesData type of variableType conversion of variableScope of variableArithmetic operatorAssignment OperatorsComparison operatorLogical operatorOperator precedence Self-study or not √√√√√√√Key Lectures √√√√√√√Teaching Method Lecture and Demonstration Lecture and Demonstration Lecture and Demonstration Lecture and Demonstration Lecture and Demonstration Lecture and DemonstrationLecture and Demonstration 121Guohua Xiong 5 ConclusionAt present, there is still a lack of research on the interactive model of curriculum standard implementation, and even less empirical research and specific teaching practice are involved. Starting from this weak link, this paper comprehensively introduces the concept, basis and process of the establishment of interactive curriculum standards in three stages of pre-class, in-class and post-class, and accordingly designs an interactive model for the implementation of curriculum standards, and validates the model through the implementation of the curriculum standard Java Programming. The results of the validation not only deepen the teachers' understanding of the implementation process of curriculum standards to a certain extent, More importantly, it can provide some theoretical basis for promoting teachers' professional development in the new curriculum and teaching reform, and provide a framework for reference and analysis for improving teachers' professional practice.FundingThis paper is Supported by Educational Planning Project of Guangdong Province in 2021 (Grant No. 2021GXJK534), Supported by Project of China Construction Education Association in 2021 (Grant No.2021177), Supported by Science and Technology Innovation Strategy Special Project in Guangdong Province in 2022 (Grant No.pdjh2022b0834), Supported by universities characteristic innovation project of Guangdong Province in 2022 (Grant No. 2022KTSCX248), Supported by School level project of Guangdong Construction Polytechnic in 2021 (Grant No.JG2021-12).References[1] Research on the interactive model of teachers'implementation of curriculum standards[D].Yangtze University,2020.[2] XIA Xuemei,CUI Yunhuo.Interaction Perspective of Teachers'Curriculum Implementation:A Construction Based on Literature Review of 40 Years[J].
