Circuits Learned by Example Online (CLEO)

工程-电气（55）该项目正在开发一个综合性的基于网络的存储库，其中包含已解决的电路分析示例问题，并以解说视频剪辑的形式提供。这些是精心编写和编辑的手绘动画，看起来像一张纸的特写，上面的文字和图画似乎“被魔法”了。教学研究的结果激发了评论的教学风格，强调对多步骤解决过程背后的基本原理的专家解释。音频评论是针对一个听众的，所以学生觉得专家在直接满足他们的需求。学生可以在观看专家视频之前在存储库中工作示例，作为对自己掌握程度的测试，或者他们可以先观看视频以获得新主题的指导。视频格式适应学生学习的各种风格和速度，因为学生可以根据需要通过暂停、重放和跳到感兴趣的点来与材料互动。音频旁白有中英文两种，还有字幕。评估工作将使用定性和定量技术来获得学生兴趣和满意度、学习成绩和保留率的指标，以及学生亚群之间这些指标的差异。目前正在评估两种传播方法：一种是依靠基于网络的存储库，这将允许免费访问，但产生静态材料；另一种是通过出版商进行商业化，这将产生动态材料，但可能需要收取使用费。就更广泛的影响而言，这个教育材料储存库可以广泛地为学生提供，无论地点或时间，并且它无缝地适合全国大多数工程专业学生所参加的每一个大二水平的两个学期线性电路课程。在一个试点版本中，这些材料在学业上有风险的学生中产生了很大的热情，并且确实有可能提高这一群体的保留率。

Engineering - Electrical (55)The project is developing a comprehensive web-based repository of solved circuit analysis example problems delivered as narrated video clips. These are carefully scripted and edited hand-drawn animations that appears as a close-up of a piece of paper with writing and drawings appearing as if "by magic". Results from research in teaching and learning motivate the pedagogical style of the commentary, which emphasizes expert explanations of the rationale behind the multi-step solution process. The audio commentary is directed to an audience of one, so the student feels that the expert is speaking directly to their needs. The student can work examples in the repository before watching the expert video as a test of their own mastery, or they can watch the videos first for instruction in a new topic. The video format accommodates various styles and rates of student learning since students can interact with the material by pausing, replaying, and skipping to points of interest as needed. The audio narration is available in English and Chinese, as well as closed-captioned text. The evaluation effort will use qualitative and quantitative techniques to obtain indicators of student interest and satisfaction, academic performance, and retention as well as differences in these among student subpopulations. Two approaches for dissemination are being evaluated: one relies on a web-based repository, which will allow free access but result in static material, while the other involves commercialization through a publisher, which will result in dynamic material but probably require a usage fee. Regarding broader impacts, this repository of educational materials is broadly available to students regardless of location or time of day and it fits seamlessly into every sophomore-level two-semester linear circuits course taken by most engineering students nationwide. In a pilot version these materials generated much enthusiasm among academically at-risk students and has real potential for increasing retention among this population.
