Video On The Computer: A Microcomputer-based Physics Laboratory

本计画将示范视像实验室习题的使用，作为以微电脑为基础的实验室物理教学完整程式的一部分。将利用最近的技术发展，使实时视频可以直接在标准计算机存储器上捕获，从而消除对激光视频光盘的需求。对于创建和存储新的物理视频实验，这应该被证明是一种非常经济有效的方法。将装配一个由12个Macintosh IIvx学生工作站和2个Macintosh Quadra视频捕捉站组成的局域网络。每个工作站将与适当的传感器和探针接口，允许数据采集和分析以及视频回放和编辑。除了标准的实验室工作外，学生还将进行选定的视频实验。物理和工程预科的学生将设计、拍摄和分析他们自己的视频实验室实验。所有课程的学生都将制作电子实验报告——音频/视频片段存储在计算机内存中，连同详细分析的文本和图形。除了视频作业，学生们还将使用电子表格来分析实验数据，这些实验数据是根据以前由NSF和fipse赞助的工作（特别是车间物理和科学思维工具）开发的。重点将是学生的积极参与和基于实践经验的概念发展。

This project will demonstrate the use of video lab exercises as part of a complete program of microcomputer-based laboratory physics instruction. Recent technological developments which allow live video to be captured directly on standard computer memory will be exploited to eliminate the need for laser video discs. This should prove to be a very cost-effective method for creating and storing new physics video experiments. A Local Area Network composed of twelve Macintosh IIvx student workstations and two Macintosh Quadra video capture stations will be assembled. Each workstation will be interfaced with appropriate sensors and probes, allowing data acquisition and analysis as well as video playback and editing. Students will perform selected video experiments in addition to more standard laboratory work. Physics and pre-Engineering students will design, shoot and analyze their own video lab experiments. Students in all courses will produce electronic lab reports-- audio/video clips stored in computer memory together with text and graphics detailing their analyses. Along with their video work, students will employ spreadsheets in analyzing data from experiments modelled on those developed under previous NSF- and FIPSE-sponsored work -- notably Workshop Physics and Tools for Scientific Thinking. The focus will be on active involvement of students and conceptual development based on hands-on experience.
