Microcomputer-Based Introductory Physics Laboratories

在物理概论课程中，大多数学生在联系依赖于时间的运动学和动力学观察量方面遇到了严重的概念困难。目前的文献表明，(A)这个问题并不是一个机构独有的，(B)基于微型计算机的实验室(MBL)可以有效地用于发展更高层次的认知技能。最成功的有据可查的方法是使用位置、速度和力传感器与装有该软件的微型计算机接口来执行实时分析。该项目使用目前市场上可用的硬件和软件，标准的实验室调查适用于认知科学的教学方法。同样的微型计算机也被用作测量仪器、分析工具、图形显示装置、作业记录库和辅导书。教学效果通过标准的假设检验程序进行评估。结果正在通过标准出版渠道、为当地高中物理教师举办的讲习班以及最终通过夏季学生讲习班传播。

The majority of the students in introductory physics courses experience serious conceptual difficulties in relating time- dependent kinematic and dynamic observables. The current literature suggests that (a) this problem is not unique to one institution, and (b) that microcomputer based laboratories (MBL's) can be used effectively to develop higher order cognitive skills. The most successful documented approach uses position, velocity, and force sensors interfaced with a microcomputer equipped with the software to perform real-time analysis. The project uses hardware and software currently available on the market, and standard laboratory investigations are adapted to a cognitive science approach to instruction. The same microcomputer is being used as measuring instrument, analytical tool, graphic display unit, repository of assignment write-ups, and tutorial aid. Pedagogical effectiveness is assessed through a standard hypothesis-testing procedure. Results are being disseminated through standard publication channels, workshops for local high school physics instructors, and ultimately summer student workshops.
