项目摘要

In this project, the Muskingum College Physics Department is developing a new curriculum for the algebra-based and calculus-based introductory physics courses as well as introducing new experimental techniques in the upper-level laboratory courses. The Workshop Physics curriculum that is currently being used for introductory courses at Muskingum College is being modified to include new modules that make use of dynamical modeling techniques and digital video methods for data collection. This project provides a digital videocassette camcorder and computer workstation for each group of three students in the laboratory. Students in the introductory physics courses use the camcorders to photograph experiments in projectile motion (including the effects of air resistance), center-of-mass motion, one and two-dimensional collisions, waves, fluid flow and electrostatic forces. They transfer the images to the computer and compare them to results of their model calculations made with spreadsheet or Dynamic Analyzer software. The curricular materials developed in this project are being made available for use at other colleges and universities. Students in the advanced physics laboratories use a new triggered video camera with one of the digital camcorders to study three-dimensional motion, do high-speed photography and record spectroscopic information. The three-dimensional motion analysis experiments include sports-related activities, which are be aimed at eventual use in introductory courses .

在这个项目中，Muskingum学院物理系正在为基于代数和微积分的物理导论课程开发新的课程，并在高级实验课程中引入新的实验技术。目前用于Muskingum学院入门课程的车间物理课程正在进行修改，以包括利用动态建模技术和数字视频方法收集数据的新模块。本项目为实验室每组三名学生提供一台数字录像机和一台计算机工作站。在物理导论课程中，学生使用摄像机拍摄弹丸运动（包括空气阻力的影响）、质心运动、一维和二维碰撞、波、流体流动和静电力等实验。他们将图像传输到计算机，并将其与用电子表格或动态分析软件进行的模型计算结果进行比较。在这个项目中编写的课程材料正在提供给其他学院和大学使用。高级物理实验室的学生使用一种新的触发式摄像机和其中一个数字摄像机来研究三维运动，进行高速摄影和记录光谱信息。三维运动分析实验包括与运动相关的活动，目的是最终在入门课程中使用。
