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.

工程-电气（55）该项目正在开发一个全面的基于网络的解决电路分析示例问题的知识库，并以视频剪辑的形式提供。这些都是精心编写和编辑的手绘动画，看起来像一张纸的特写镜头，上面的文字和图画看起来就像“魔法”一样。 教学研究的结果激发了评论的教学风格，强调专家对多步骤解决方案背后的原理的解释。音频评论是针对一个观众，所以学生觉得专家是直接说话，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。视频格式适应各种风格和学生的学习速度，因为学生可以通过暂停，重播和跳到感兴趣的点与材料进行互动。音频解说有英文和中文两种版本，以及字幕文本。评估工作将使用定性和定量技术，以获得学生的兴趣和满意度，学习成绩和保留以及学生群体之间的差异的指标。 目前正在评估两种传播方法：一种是依靠网络储存库，允许免费查阅，但产生静态材料;另一种是通过出版商进行商业化，产生动态材料，但可能需要收取使用费。关于更广泛的影响，这个教育材料库广泛提供给学生，无论地点或时间，它无缝地融入全国大多数工程专业学生所参加的每一个二级两学期线性电路课程。 在试点版本中，这些材料在学业有问题的学生中激发了很大的热情，并具有真实的潜力，可以提高这一群体的保留率。
