CER: Collaborative Research: Computing Education through Collaborative Debugging

华盛顿大学和俄勒冈州州立大学将研究如何在个性化的、社交的在线学习环境中教授调试和计算技能。研究人员将创建一个交互式网站，向学习者提供一系列调试难题，让他们以自定进度的方式并与同龄人合作学习诊断策略和计算概念。该网站还将允许学习者创建自己的调试难题，与朋友，家人和世界分享，从而形成一个社会学习的在线社区。使用这种设计，该项目将调查明确的指导调试策略对学习者学习基本编程概念的能力的影响，以及社会学习功能对学习成果和参与的影响。该项目还将对如何教授调试以及如何将这种教学整合到计算的其他方面的教学中做出基本的发现。评估将包括两个控制实验室实验，每年的夏令营涉及200多名美国青少年，并在全球范围内部署的网站。这个项目是一个更大的努力，以提高美国青少年的计算素养和对计算职业的兴趣。该项目对社会学习的关注对于扩大计算的参与尤为重要，使青少年能够在支持和协作的环境中学习计算，而不是在当今阻碍许多青少年的高度竞争环境中学习。此外，由于该网站只需要互联网连接和网络浏览器，而不需要安装软件或特殊设备，该项目还将改善获得有效的循证计算机教育的机会，使那些只能在公共图书馆或学校上网的学习者也能获得这种教育。这些努力不仅将提高美国公民在信息技术工作方面的全球竞争力，还将帮助更广泛的公民更好地理解和调试他们周围日益基于软件的世界。

The University of Washington and Oregon State University will investigate how to teach debugging and computing skills in personalized, social, online learning settings. The investigators will create an interactive website that presents a series of debugging puzzles to learners, allowing them learn diagnostic strategies and computing concepts in a self-paced manner and in collaboration with their peers. The website will also allow learners to create their own debugging puzzles to share with friends, family, and the world, resulting in an online community of social learning. Using this design, the project will investigate the effect of explicit instruction on debugging strategies on learners' ability to learn basic programming concepts and the effect of social learning features on learning outcomes and engagement. The project will also contribute basic discoveries on how to teach debugging and how such teaching can be integrated into instruction on other aspects of computing. Evaluations will include both controlled laboratory experiments, annual summer camps involving over 200 U.S. teens, and a worldwide deployment of the website.This project is part of a larger effort to increase both computing literacy and interest in computing careers on the part of U.S. teens. This project's focus on social learning is particularly important for broadening participation in computing, allowing teens to learn computing in supportive and collaborative settings, rather than the highly competitive settings that tend to deter many teens today. Moreover, because the website will only require an Internet connection and a web browser, and not software installations or special devices, the project will also improve access to effective, evidence-based computing education, reaching learners who only have Internet access at public libraries or at school. These efforts will not only improve U.S. citizens' global competitiveness for information technology jobs, but also help the broader citizenry better understand and debug the increasingly software-based world around them.
