Pearson Computer Delivered Testing Test Administra
1. IntroductionPearson’s Computer Delivered Test (CDT) program, using patented Ordinate® speech processing technology, enables test administrators to deliver Versant language tests on a test center computer and upload completed tests for scoring.This Guide is written for administrators of CDT. It explains how to:•Configure Testing Center Computers•Download Tests•Take a TestThis Guide assumes that you have successfully installed the CDT program on each of the computers on which you intend to administer tests. If you have not completed the installation process, please consult the CDT Installation Guide which can be downloaded on Pearson’s website:https:///english/versant/cdt.html2. Configuring Testing Center ComputersBefore administrating a test, prepare the computer for test delivery. Preparation involves three steps:•Verify screen resolution settings•Verify that the microphone is working and that the volume is properly set•Verify bandwidth of your Internet connection for your expected testing volume2.1 Verify screen resolution settings1.Open the Control Panel.2.In the Control Panel, click Display.3.Click the Settings tab.4.Check the screen resolution setting in the Screen Area. It should be at least 1024 x 768.5.Move the slider to adjust the settings to the required minimum if needed.2.2 Verify microphone volume levelMicrophone volume level for Windows XP, 7, 8 and 10 is adjusted automatically by the CDT Client. For Windows Vista it is required that microphone volume level is adjusted by following these steps:1.In the Start Menu, locate the search box, type Speech Recognition Options and press Enter.2.In the Speech Recognition Options Window click on Set up microphone.3.Follow the instructions provided and click Next.4.Read the full sentence that appears on the screen into the microphone, then click Next.5.Click Finish, to complete your microphone calibration.2.3 Verify bandwidth for expected testing volumeThe CDT program operates by downloading a test to the local machine and then uploading theresponses once the test is complete for scoring. This requires network access to an Internet connection of sufficient bandwidth to accommodate the volume of concurrent testing that you plan to conduct inyour test center. (Note: In addition to a real-time mode, CDT also supports an option that allows you to pre-load tests, complete the tests offline, and then reconnect later to upload results for scoring). To ensure your test center has adequate Internet bandwidth, please consult the document “Network and Bandwidth Requirements.”3. Downloading TestsAfter the CDT software has been installed and each computer has been configured, testing can proceed. For test takers to be able to take a test, a Test Identification Number (TIN) must be entered for each test to download the appropriate test materials. There are 2 administrative options for downloading TINs:1. Pre-loading TINs before scheduled testing: As the test administrator, you can pre-load thecomputer with tests before your scheduled testing. We recommend this method if:a.You have any concerns about the speed or performance of your Internet connection.‡b.You plan to conduct testing on multiple computers at the same time.‡c.You need to conduct testing on a computer that cannot be connected to the Internetduring the test (for example, if you conduct testing with a laptop in a remote location).2. On-demand downloading of TINs: If you can stay connected to the Internet and have enoughbandwidth for the volume of testing you plan to do‡, you may also provide TINs to the testtakers and instruct them to enter the TIN as the first step of their test. The test materials willdownload then, on-demand. This download will need to complete before the test taker canbegin the test.‡ To verify that you have enough bandwidth for the volume of testing that you plan to do, please consult the document titled “Network and Bandwidth Requirements.”Note that he same TINs cannot be downloaded to multiple computers. If a batch or TIN was mistakenly downloaded to the incorrect computer, please contact Pearson Support (+1 650-470-3503 or*********************) to release the TIN(s) from the computer.3.1 Getting Started1.Ensure the computer is connected to the Internet.2.Start CDT by double-clicking the CDT Client icon on the desktop.3.Go to Menu located on the top right of the screen.4.Click on Administration.5.Enter your ScoreKeeper Username and Password to enter the Administrator’s configurationpreferences and click Enter. If you do not have a ScoreKeeper Username and Password,contact your Account Manager.3.2 Pre-loading TINs Before Scheduled TestingTests can be pre-loaded by batch, or by Test Identification Numbers (TINs).1.In the Administrator menu, click Download Tests.2.To download an entire batch of testsa.Click the Batch Key tab.b.Enter the alpha-numeric batch key into the space provided (Note: the batch key can befound by going to the batch in your ScoreKeeper account and clicking the TestMaterials link).c.Click Enter. CDT will then download all of the unused TINs in that batch.3.To download individual Test Identification Numbers (TINs) from multiple batchesa.Click the TIN(s) tab.b.Enter each TIN or a comma-separated list of TINs.c.Click Enter.3.3 On-Demand Downloading of TINsTo download tests on-demand, you may also provide TINs to the test takers and instruct them to enter the TIN as the first step of their test.1.Start CDT, enter the TIN in the space provided and click Enter.2.The TIN will then begin to download. The download progress will be displayed. Do not exit CDTwhile the TIN is downloading.3.Once the TIN is fully downloaded, CDT will display the headset (and for speaking test,microphone) check.3.4 View TestsOnce you have downloaded tests to the computer, you can view all the unused tests that are available for use on this computer.1.In the Administrator menu, click View Tests.2.Verify the total number of tests available match your records.3.Click Refresh TIN List to check the availability of the local test inventory against yourScoreKeeper account.4. Taking a TestTo begin a test, the administrator or test taker must enter a valid Test Identification Number (TIN) into the Welcome screen of the CDT Client.1.Start CDT and go to Home page.2.Give the test taker a TIN.3.The test taker enters the TIN in the space provided and clicks Enter to start the test.If the TIN has been pre-loaded, then the test will begin immediately, starting with an audio check. If not, then the TIN will be downloaded before the test can begin.4.1 Audio Volume and Microphone CheckAt the beginning of each test, test takers will go through an audio volume check. For speaking tests, test takers will also go through a microphone volume check.1.The test taker is instructed to put on their headset (for speaking tests) or headphones (forwriting tests) as shown on the screen.2.Click Next to proceed.3.The test taker listens to a passage and is instructed to move the slider to change the volume.Note: Test takers can also change the volume during the test in the upper right corner of thescreen.4.Click Next to proceed.5.For speaking tests, test takers are asked to read a sentence into their microphone to verify thatit is working correctly.6.If CDT cannot verify that the microphone is working correctly, an error message will appear.Follow the instructions to complete the microphone check. Is important to verify that themicrophone is working properly. If the microphone is unable to properly record the test taker’s responses, then that test’s score may be affected. If error messages persist, exit CDT and check the microphone volume and functioning using your computer’s audio and microphone controls (see Section 2.2).7.Once the calibration checks are complete, the test will begin.4.2 Completing the TestWhen the test taker is finished, the application will prompt the test taker to click Finish. If the computer is connected to the Internet with the test taker clicks Finish, then the test responses will be automatically uploaded to the Versant system for scoring. Note: if the test taker exits CDT before clicking Finish, then the test will not be completed and sent for scoring.If the Internet connection was disabled during testing, administrators must reconnect to the Internet and launch the CDT Client for the response files to be automatically submitted for scoring. Keep CDT open until all responses have been uploaded. You can check the status of completed tests by doing the following:1.Go to Menu located on the top right of the screen.2.Click on Administration.3.Enter your ScoreKeeper Username and Password to access the Administrator’s configurationpreferences and click Enter. If you do not have a ScoreKeeper Username and Password,contact your Account Manager.4.In the View Tests section, click Refresh TIN List.5.Look at the “Sessions” information. If there are tests that still need to upload for scoring, theywill be listed here. If you see “No local sessions/response,” then all completed tests have been uploaded and you can exit CDT.4.3 Checking ScoresTest scores are available within minutes after the voice files are successfully submitted to the Versant system. To view scores, go to https:///english/versant/score.html or log into your ScoreKeeper account.5. TroubleshootingThis section contains suggestions for troubleshooting problems. If you encounter any problem that cannot be resolved, contact our Technical Support team at ********************* or +1 650-470-3503.5.1 Microphone ErrorsMicrophone volume levels for Windows XP, 7, 8 and 10 users will automatically adjust in the CDT Client. For Windows Vista users, follow the steps in Section 2.2 to verify the microphone volume level. If the volume levels have been verified but error messages are still occurring, it could be for one of the following reasons:1.The microphone has not been positioned correctly as shown on the computer screen.2.The microphone may not be compatible or working properly with the computer. Exit the CDTClient, and go to the Control Panel. Select Sound and Audio Devices and then click on theVoice tab. Next, click on the Test Hardware button and follow the steps on the screen to make sure the microphone is working properly.5.2 Downloading TestsIf you are experiencing difficulties downloading tests, it could be for one of the following reasons:1.The Batch Key may not be valid. The Batch Key is a 12 character alpha-numeric code that isunique to each batch. The Batch Key can be found in your ScoreKeeper account List Batches >> Test Materials for each batch.2.The Batch has no available tests. If the batch is already downloaded into your computer it isrecommended to Refresh the TIN list before starting using those TINs (see Section 3.3), toensure the most up to date list of unused TINs are displayed. Only unused TINs will bedownloaded to the computer.3.The TIN(s) or Batch cannot be located. The TIN(s) or entire batch may have already been used. Loginto your ScoreKeeper account and go to List Batches >> View Scores and select Click here to see a list of all tests in this batch to ensure the TIN(s) or batch are unused.5.3 Scoring DelaysTest scores are typically available in ScoreKeeper within minutes of completing a test and uploading the responses to the Versant Testing System. If scores are not available within 15 minutes, it could be for one of the following reasons:1.Your internet connection may have been interrupted. Exit the CDT Client, re-connect to theInternet, and open the CDT Client. Tests will be automatically uploaded to the Versant testing system and the scores will become available shortly.2.The Versant testing system may be experiencing a brief outage. Check with your Account Managerto see if there is any scheduled maintenance downtime and when the system will becomeavailable. Once the outage is complete, tests that were administered during the outage window will be scored on a first-come, first-served basis to the best of our scoring capacity.。

基于聚类分析的电商平台精准营销方法研究
I G I T C W经验 交流Experience Exchange188DIGITCW2023.10随着移动互联网技术的发展,电商平台已经成为人们购物的主要渠道之一。
然而,电商平台竞争激烈,如何吸引用户、提高用户留存率和购买率成为电商平台运营者需要解决的问题[1]。
精准营销是当前电商平台营销的热点之一,其核心在于根据用户数据进行个性化推荐和优惠券奖励,以提高用户忠诚度和消费频次[2]。
而聚类分析作为一种常用的数据挖掘方法,能够将大量的非结构化数据转换成有机可视的群体模式,因此也被广泛应用于电商平台的精准营销中。
本文旨在探讨如何基于聚类分析实现电商平台的精准营销,并进一步研究该方法在使用与维护方面的问题。
1 聚类分析概述聚类分析是数据挖掘领域中的经典算法之一,主要用于将相似的对象归为同一组或类别。
其核心思想是通过计算不同数据点之间的距离,将其按照相似度进行分类。
不同的聚类方法存在着各自的特点和应用场景。
在聚合聚类中,每个数据点最初都作为一个单独的簇,然后通过不断合并最接近的两个簇来生成更大的簇。
在分裂聚类中,则是从整个数据集开始,逐步将其分成较小的子集,直到每个数据点都被划分为一个单独的簇。
聚类分析在实际生活中被广泛使用[1]。
例如,在市场营销领域中,它可以帮助企业在海量消费者中找到目标客户,并制定有针对性的推销策略;在社交网络中,它可以将兴趣相似的用户分为一组,使得精准营销和产品推荐更加有效。
此外,在医学、生物学、工程学等领域中也有广泛的应用。

the"standard deviation of responses across a set of consecutive item responses for an individual"(Dunn,Heggestad,Shanock,&Theilgard,2018,p.108).By default,the IRV is calculated across all columns of the input data.Additionally it can be applied to different subsets of the data.This can detect degraded response quality which occurs only in a certain section of the questionnaire(usually the end).Whereas Dunn et al.(2018)propose to mark persons with low IRV scores as outliers-reflecting straightlining responses,Marjanovic et al.(2015)propose to mark persons with high IRV scores-reflecting highly random responses(see References).Usageirv(x,na.rm=TRUE,split=FALSE,num.split=3)Argumentsx a matrix of data(e.g.survey responses)na.rm logical indicating whether to calculate the IRV for a

如何参加美国教师资格证考试(cbest、cset)
如何参加美国教师资格证考试(CBEST、CSET)在美国当中小学老师,虽然每一个州都有自己的标准,但基本都要求老师有教学资格证(Teaching Credential)才能教书。
在加州中小学通行的教学资格证有三种:专业资格证(Professional Cleared Credential);初级资格证(Preliminary Credential);临时资格证(Emergency Credential)执教幼儿园到9年级学生的教师应持多科资格证,而执教高中的教师通常持单科资格证。
一、教师资格证的要求:1、临时资格证的要求:需要有大学学位,通过CBEST考试。
临时资格证只可以担任代课教师,不能成为正式教师,而且,每年必须修读一定的教育学分,才能更换资格证。
2、初级资格证的要求:(1)通过加州基本教育技能考试CBEST(California Basic Educational Skill Test)。
(2)大学毕业后在教育学院修读30个教育的学分,完成教学实习和其它的要求。
(3)或者在通过CBEST考试后,在大学教育学院获得教育学硕士以上学位。
3、专业资格证的要求:教师拿到初级资格证后,三年内必须在大学修读60个学分(相当于两年的课程)研究生程度的课程,才可以把初级资格证换成专业资格证。
得到专业资格证以后,必须每五年更新一次。
二、CBEST考试:在加州要取得教学资格证并不是一件容易的事情,CBEST考不及格,教育学院就不会录取你就读教学资格证课程,无法满足修读教育学分的条件。
CBEST是一个长达四小时的考试,分英语阅读,英语作文和数学三部分。
1、英语阅读程度只相当于美国8年级,阅读考试的内容中大部份是考美国特有的文化,以及生物,医学,人类学,考古学方面非常专门的英语单词。
2、英语作文从前是要求在一个小时之内写两篇作文,一篇是小说,一篇是议论文。
现在改为两个小时。
假如不熟悉英语作文的“八股”要求,几乎不可能及格的。

Credito Emiliano(Credem)OpenTextTM Data Express产品简
Credito Emiliano (Credem)OpenT ext TM Data Express improves time-to-market and ensures full data privacy compliance.Overview Credito Emiliano S.p.A. (Credem) is ranked as the 18th largest bank in Italy by total assets. The bank has several divisions, including retail bank-ing, corporate banking, and private banking. Challenge Banks such as Credem demand that IT sup-ports key business objectives, maximizes customer satisfaction, and meets all forms of governance and compliance requirements, especially in this highly regulated industry. T o achieve this, IT must offer the highest levels of application quality; and this means a rigorous, comprehensive and security-conscious test-ing and QA infrastructure. But how can IT de-liver business value through application quality, while it has to respect data privacy rules and work within the constraints of its infrastructure? Ernesto Centrella, T est Department Manager at Credem explains: “We wanted to save disk space, while accelerating the data alignment process from the production to the test envi-ronments. This was a manual and time-con-suming process with our application managers having to certify that the data had been fully masked and was data privacy compliant be-fore moving it into a test environment. We also needed to improve performance and achieve a faster time-to-market by reducing the testing preparation and execution time. We wanted to improve the testing data quality, while respect-ing privacy.”Solution Local services provider SI.DE. Soft, a key part-ner for Credem, took charge of the project and soon highlighted OpenText TMData Expresswhich has a special focus on data masking and data subsetting; features Credem was very interesting in. Using Data Express, a process was put in place where any data which could reveal a customer’s identity was automatically masked in the test environment. T est environ-ments were set up in parallel with the produc-tion environment, creating a repeatable andreliable test environment to support all testing activities. T ests are carried out on test dataand the results are verified by analyzing the impact on the various files. With the flexibility At a Glance ■ Industry Financial Services ■ Partner SI.DE. Soft s.r.l.■ Location Italy ■ Challenge Credem wanted to automate a manual and time-consuming application testing process to improve performance and achieve a faster time-to-market. It needed to improve the test data quality, while respecting data privacy in the highly regulated banking industry.■ Products and Services Data Express ■ Success Highlights + 80% reduction in testing environment storage requirements + 50% improvement in batch testing time + Full data privacy compliance+ Enhanced application quality +Reduced time-to-market“In some cases we manage particularly sensitive data, such as US fiscal codes. The built-in flexibility in Data Express has made this easy for us.”GIULIO FERRETTI T echnical T est Analyst CredemCase StudyData Express offers, every product process was adapted to Credem’s specific needs, us-ing custom APIs and exit routine mechanisms.Giulio Ferretti, T echnical T est Analyst at Credem, comments on the use of Data Express: “We like that we can manage our different platforms and databases from a single central repository. The Data Life Cycle feature locates every new entity (a new or changed data structure) and catalogs it in the repository, minimizing rework.”Data Express provides extraction simulation to show elapsed time, CPU consumption, and test data storage capacity requirements. This helps prevent errors occurring during the ex-traction of production data. It uses the source data index to improve performance. Parallel processes can be executed so that the overall elapsed time is much shorter.Data Express allows Credem to improve the testing process by rapidly and consistently providing test data when needed and in the required format. Ferretti comments: “In some cases we manage particularly sensitive data, such as US fiscal codes. The built-in flexibility in Data Express has made this easy for us.”ResultsUsing Data Express, the testing environment now uses the exact same data quality as the production environment, making it possible to reproduce test cases which couldn’t be certi-fied before. This means the testing data quality has improved resulting in higher quality appli-cations with far fewer issues in production.The data subsetting within Data Express has allowed faster testing processes, improving the time-to-market of business applications.Thanks to the data protection provided by data masking, Credem can now open up its systems to allow its partners to test their applications directly on the relevant environments, with no risk to data compliance whatsoever.Centrella on the benefits: “With Data Express we have seen a reduction of 80% in our test-ing environment storage requirements. As we run in a mainframe environment, this is a direct MIPS saving for us. We have also achieved a 50% performance improvement for our batch testing processes. This translates to a faster time-to-market with higher quality applica-tions. With the automation in place to gener-ate and maintain test environment data, our developers can focus on developing and test-ing new functionality to cover Credem’s busi-ness needs.”He concludes: “We have gained savings in many areas: disk space costs, MIPS/CPU usage, a more stable production environment, and a faster time-to-market for our business applica-tions. Best of all though, Micro Focus (now part of OpenT ext TM) and SI.DE. Soft helped minimize any compliance risk to data privacy. They have given us the confidence that our data is secure and fully compliant.”Learn more at/opentext268-000042-001 | O | 05/23 | © 2023 Open T ext。
