Multimedia-focused Kinematics Questions: An Innovative Approach to Teaching Kinematics

物理（13）本课题是开发多媒体运动学问题，并研究其对学生理解的影响。多媒体问题是学生必须从多媒体（在这种情况下是动画）中收集数据来回答问题的问题。动画是使用Physlets创建的，Physlets是Wolfgang Christian开发的物理Java小程序。问题被交付，学生的反应收集使用基于网络的家庭作业系统称为WebAssign。物理问题是基于已知的学生在运动学的困难。从研究中开发的诊断工具-TUG-K（理解图形运动学的测试）和拟议的ATM（运动的动画测试）-首次被用来探索多媒体问题对学生运动学概念理解的影响。该项目是：（1）如果发现这些问题有效，则为在介绍性物理课程中开发类似问题提供模型，以及（2）开发一套可通过网络交付的运动学问题，任何教授物理的人都可以立即在课堂上使用。这些问题可以从WebPhysics服务器下载HTML文件，可以在WebAssign问题数据库中找到，也可以在即将出版的《Teaching with Physlets》一书的配套CD中找到。 该项目针对的DUE主题是多样性，教师培训和教育中的技术整合。

Physics (13) This project is developing Multimedia-focused kinematics questions, and studying their effect on student understanding. Multimedia-focused questions are questions where students must collect data from multimedia (animations in this case) to answer the question. Animations are being created using Physlets, which are physics Java applets, developed by Wolfgang Christian. Questions are delivered, and students' responses collected using a web-based homework system called WebAssign. The Physlet questions are based on known student difficulties in kinematics. Diagnostic instruments developed from research -- the TUG-K (Test of Understanding GraphsKinematics) and the proposed ATM (Animated Test of Motion) -- are being used to probe for the first time the effect of multimedia-focused questions on students' conceptual understanding of kinematics. The project is: (1) providing a model for the development of similar questions across the introductory physics curriculum if these questions are found to be effective, and (2) developing a set of kinematics questions, deliverable via the web, that anyone teaching physics can immediately use in their class. The questions are downloadable as HTML files from WebPhysics servers, available in the WebAssign question database, and available on the companion CD to an upcoming book Teaching with Physlets. DUE themes targeted by the project are diversity, teacher preparation, and integration of technology in education.
