Continued Development of Interactive Examples for Concept-Based Problem-Solving in Introductory Undergraduate Physics Curricula

该项目扩展了“互动实例”的开发，这是一种促进基于概念的问题解决的基于网络的练习，包括为准备不足的学生开设的初级课程以及基于微积分的热物理和量子物理课程。 这个扩展补充了已经制作的模块，包括完整的基于微积分的力学和电磁课程的IE。 除了已经证明的统计学显着改善后，IEs被引入到这些课程的学生表现，该项目还参与了一个正在进行的评估过程，以了解负责这种改进的机制。根据从评估过程中学到的原则，我们正在改进现有的独立实体，并为介绍性序列的其余部分创建新的独立实体。所有独立实体都在网站上维护（http：//wug.physics.uiuc.edu/courses/ie.html），并免费向公众提供。从社区学院到研究型大学，共有14所院校在其课程中采用工业教育作为学分。 通过一项出版协议，可以在网站之外进行传播，我们对独立教育在提高学习成果方面的效果进行的调查结果在国家会议上和同行评审的期刊上发表。

This project extends the development of "Interactive Examples" (IEs), web-based exercises that promote concept-based problem solving, to include an initial course for under-prepared students and the calculus-based thermal physics and quantum physics courses. This extension compliments the already produced modules that include complete sets of IEs for calculus-based mechanics and electricity & magnetism courses. In addition to already demonstrated statistically significant improvements in student performance after IEs were introduced into these courses, the project is also engaged in an ongoing evaluation process to understand the mechanisms responsible for this improvement. Guided by the principles learned from this evaluation process, we are refining our existing IEs, and creating new IEs for the remaining components of the introductory sequence.All IEs are maintained on a website (http://wug.physics.uiuc.edu/courses/ie.html) and freely available to the general public. Fourteen institutions, ranging from community colleges to research universities, are adopting IEs for credit use in their courses. Dissemination beyond the web site is available through a publishing agreement and the results of our investigations into the effectiveness of IEs on enhancing learning gains are presented at national meetings and in peer-reviewed journals.
