Community Resources for Automated Grading

这个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代码的能力，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，迫使他们不断地表达自己对代码应该如何表现的理解。学生们练习写下关于他们的代码应该如何运行的假设，然后通过执行他们的测试来验证这种理解。Web-CAT已在一家机构进行了正式评估，并已被另外三家机构成功采用。这个项目有四个目标：将Web-CAT从一个概念的证明扩展到一个可以被广泛分发和应用的状态，无论是希望自动化作业评分实践的最终用户，还是希望建立在这个平台上开发和评估他们自己的自动化评估技术的教育研究人员。为想要使用Web-CAT的教师开发教育材料，包括获取最佳实践的综合教学手册、示例作业、如何使现有作业适应自动评估的方法，以及为采用者提供的研讨会。发展一个教育工作者社区，他们希望使用、扩展和支持Web-CAT及其所支持的教学策略。该社区由wiki和邮件列表提供支持，并在专业活动（如SIGCSE专题讨论会）上举行了一些无足轻重的会议。评估Web-CAT在不同环境下的有效性。

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.
