VideoGraph Development Project

VideoGraph是一种用于高中和大学物理实验室入门的教学工具。它允许学生录像运动事件，并利用微型计算机的绘图功能，同时检查和分析运动。在1989年获得奥豪斯奖的最初软件包的修订版中，开发人员正在增强程序的原始功能，包括高质量彩色图像和支持访问视频光盘。此外，它将允许学生保存以前记录的事件，无论是录制在录像带上还是从视频光盘上播放，并使用绘画应用程序或编程语言“绘制”事件。通过这种方式，学生将能够分析之前记录的事件，甚至是模拟的微世界，其中运动规律被预先编程到系统中。除了开发软件之外，本项目还将进行课堂研究，以促进其融入传统的课堂、实验室和家庭作业活动。它还改进了先前开发的学生动作图像解释技能测试，并计划开发观察方案和替代评估方法，以验证这些材料对学生理解的影响。

VideoGraph is an instructional tool created for use in introductory physics laboratories at the high school and college levels. It allows students to videotape motion events, and using the graphing capabilities of a microcomputer, to simultaneously examine and analyze the motion. In this revision of the initial software package, which received the Ohaus Award in 1989, the developers are enhancing the original capabilities of the program, including high quality color images and support for access to videodiscs. In addition, it will allow students to save previously recorded events, whether recorded on videotape or played from a videodisc, and "draw" events using paint applications or programming language. In this way, students will be able to analyze previously recorded events or even simulated microworlds in which the laws of motion are preprogrammed into the system. In addition to developing the software, this project will conduct classroom studies to facilitate its integration into traditional classroom, laboratory, and homework activities. It is also refining a previously developed test of student skills in motion graph interpretation, and plans to develop observational schemes and alternative assessment methods to verify that the materials are having an impact on student understanding.
