CER: openHTML, a Scaffolded Web Development Tool to Support Elementary Computational Literacy

德雷塞尔大学将与Mozilla基金会和内布拉斯加州大学奥马哈分校的合作伙伴一起，调查初级网络开发经验对学习者对计算技能和概念的掌握和感知的影响。在正式和非正式的环境中使用介绍性的网页编辑器打开HTML和Thimble；他们将吸引那些很少或没有创造性计算经验的初学者构建他们的第一个网页，学习HTML和CSS。他们将进行观察性研究与测试相结合，以了解学习者在网络开发方面的经验，并确定标志着反复出现的错误、恢复、误解和能力的活动模式，并将使用这些发现来识别初学者代码中的错误和能力标记。广泛的计算能力是有竞争力的劳动力和充满活力的经济的重要组成部分。通过降低对计算机的舒适和能力的障碍，该项目旨在1)吸引那些可能不会出现在计算机科学教育雷达上的创造性计算活动的个人2)改善网络开发教育者和学习者可用的工具3)扩展有关早期计算思维技能发展的科学知识。

Drexel University, together with partners at Mozilla Foundation and the University of Nebraska at Omaha, will investigate the impact of beginning web development experiences on learners' mastery and perceptions of computational skills and concepts. Using introductory web editors open HTML and Thimble in both formal and informal settings; they will engage beginners who have little or no experience with creative computation in constructing their first web pages and learning HTML and CSS. They will conduct observational studies paired with testing to understand learners' experiences with web development and identify activity patterns that signal recurring errors, recoveries, misconceptions and competencies and will use these findings to identify markers of error and competency in beginner's code. Widespread computational competency is a vital component of a competitive workforce and vibrant economy. By lowering the barriers to comfort and competence with computing, this project aims to 1) engage individuals who may not otherwise appear on the computer science education radar in creative computational activities 2) improve the tools available to web development educators and learners and 3) extend scientific knowledge about the development of early computational thinking skills.
