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.

该项目扩展了“互动示例”（IEs）的开发，这是一种基于网络的练习，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。这个扩展补充了已经生产的模块，包括全套的基于微积分的力学和电磁学课程的IEs。在这些课程中引入工业工程学后，学生的表现在统计上已经有了显著的改善，除此之外，该项目还参与了一个持续的评估过程，以了解这种改善的机制。在从评估过程中学到的原则的指导下，我们正在改进现有的ie，并为介绍序列的其余组件创建新的ie。所有的ie都在一个网站（http://wug.physics.uiuc.edu/courses/ie.html）上保存，并免费提供给公众。从社区学院到研究型大学，共有14所院校在课程中采用ie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IEs在提高学习收益方面的有效性的调查结果在国家会议和同行评议的期刊上发表。
