Development of a CD-ROM Based Multimedia Teaching Package for Introductory Materials Science and Engineering

提出了一个为期三年的项目，开发一个基于cd - rom的多媒体包，用于材料科学与工程入门课程的教学。这个包的目的是满足传统课程的大部分讲课目的，以便课堂时间可以用于通常在辅导课或复习课上进行的活动。这样做的动机是与传统讲座相比，这种课程的教学效率有所提高。该软件包将围绕由多媒体导演创建的动画、辅助程序和视频片段构建，这些视频片段显示了在单独项目中创建的录像实验室实验的摘录，以及录像讲座演示。在过去的一年里，宾夕法尼亚大学已经开发出了制作动画和用计算机编辑录像带所必需的技术，而且已经具备了所需的设备和软件。项目的前两年将主要致力于动画和视频片段的创作，并通过课堂使用对其进行评估。它们将通过CD-ROM输出到其他机构供其使用和评价。将这些与文本和语音整合到交互式教学包中的技术开发也将在前两年进行，第三年将致力于完成该包并在课堂使用中进行评估，以便在项目期间进行最后的调整和修改。该教学包将以一本正在出版的新教科书为基础，这是该学科新方法发展的一部分。这与传统的课程类型有所不同，因为它将主题重新组织为两个大的案例研究，一个是关于结构材料的，使用自行车，另一个是关于设备材料的，使用WalkmanTM。宾夕法尼亚大学和其他地方的经验表明，在入门课程中，这种方法比传统方法更有效，特别是对于非材料科学和工程专业的学生。

9455333 McMahon A three-year program to develop a CD-ROM-based multimedia package for the teaching of an introductory course in materials science and engineering is proposed. It is intended that this package will serve most of the purposes of the lectures in a traditional course so that the classroom time can be devoted to the activities normally carried out in tutorial or recitation sessions. The motivation for this is the increase in teaching effectiveness of such sessions compared to traditional lectures. The package will be built around animations created with Multimedia Director and ancillary programs and video segments showing excerpts from videotaped laboratory experiments created in a separate project, as well as videotaped lecture demonstrations. The techniques necessary for the creation of the animations and for computer-based editing of video tapes have been developed at Pennsylvania during the past year, and the equipment and software necessary for this are already available. The first two years of the project will be devoted mainly to creation of animations and video segments and to evaluating them by classroom use. They will be exported to other institutions via CD-ROM for their use and evaluation. The development of the technique of integrating these with text and voice into an interactive teaching package will also be carried out in the first two years, and the third year will be devoted to completing this package and evaluating it in classroom use so that final adjustments and modifications can be made during the period of the project. The teaching package will be based on a new textbook, now being published, which is part of the development of a new approach to the subject. This is a departure from the traditional type of course in that it reorganizes the subject into two large case studies, one on structural materials, using the bicycle, and the other on device materials, using the WalkmanTM. Experience at Pennsylvania and elsewhere has s hown this to be more effective that the traditional method in an introductory course, especially for nonmajors in materials science and engineering.
