Community Resources for Automated Grading

该项目扩展并完全实现了Web-CAT，即基于Web的自动化测试中心。Web-CAT是一个创新的自动评分平台，它关注的是学生测试自己的代码有多好，而不是评估程序输出的正确性。Web-CAT鼓励学生练习理解、分析和评估技能，迫使他们不断地阐明自己对代码应该如何行为的理解。学生练习写下关于他们的代码应该如何行为的假设，然后通过执行他们的测试来实验验证这一理解。WEB-CAT已在一家机构进行了正式评估，并已被其他三家机构成功采用。该项目有四个目标：将Web-CAT从一个概念验证扩展到一个可以广泛分发和应用的状态，这既可以由希望实现作业评分自动化的最终用户进行，也可以由希望在该平台上建立以开发和评估他们自己的自动评估技术的教育研究人员进行。为想要使用Web-CAT的教师开发教育材料，包括一本全面的教学手册，其中介绍了最佳实践、示例作业、如何将现有作业调整为自动评估，以及为采用者举办的研讨会。开发一个想要使用、扩展和支持Web-CAT及其实现的教学策略的教育工作者社区。该社区得到了wiki和邮件列表的支持，以及在专业活动(如SIGCSE研讨会)上举行的物以类聚的会议。评估Web-CAT在不同环境中的有效性。

This project expands and fully implements Web-CAT, the Web-based Center for Automated Testing. Web-CAT is an innovative automated grading platform that focuses on how well students test their own code, rather than assessing the correctness of a program's output. Web-CAT encourages students to practice comprehension, analysis, and evaluation skills by forcing them to continually articulate their own understanding of how their code should behave. Students practice writing down hypotheses about how their code should behave, and then experimentally validate this understanding by executing their tests. Web-CAT has been formally evaluated at one institution and has been successfully adopted by three others. This project has four objectives:To expand Web-CAT from a proof of concept to a state where it can be distributed and applied widely, both by end-users who wish to automate their assignment grading practices, and by educational researchers who wish to build on this platform to develop and evaluate their own automated assessment techniques. To develop educational materials for instructors who want to use Web-CAT, including a comprehensive teaching manual capturing best practices, example assignments, how-to's on adapting existing assignments for automated assessment, and workshops for adopters. To develop a community of educators who want to use, extend, and support Web-CAT and the teaching strategies it enables. The community is supported by a wiki and a mailing list, together with birds of-a-feather-style meetings at professional events such as the SIGCSE Symposium. To evaluate the effectiveness of Web-CAT in a diverse set of contexts.
