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”(IES)的开发，这是一种基于网络的练习，旨在促进基于概念的问题解决，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。这一扩展是对已经生产的模块的补充，这些模块包括基于微积分的力学和电力与磁学课程的全套IES。除了在这些课程中引入独立专家系统后，学生的成绩在统计上已经有了显著的改善，该项目还参与了一个持续的评估过程，以了解导致这种改善的机制。根据从这次评估过程中学到的原则，我们正在改进我们现有的独立专家系统，并为介绍序列的其余部分创建新的独立独立专家系统。所有独立独立专家系统都保存在一个网站(http://wug.physics.uiuc.edu/courses/ie.html))上，并向公众免费提供。从社区学院到研究型大学，有14所院校在其课程中采用IES作为学分。网站以外的传播可通过出版协议获得，我们对独立专家系统在提高学习成果方面的有效性的调查结果已在国家会议和同行评议的期刊上公布。

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.
