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.

在物理导论课程中，大多数学生在联系随时间变化的运动和动态观测时，都会遇到严重的概念性困难。目前的文献表明：(a)这个问题不是一个机构所独有的，(b)基于微型计算机的实验室（MBL’s）可以有效地用于发展更高层次的认知技能。最成功的记录方法是使用位置、速度和力传感器与配有软件的微型计算机接口进行实时分析。该项目使用了目前市场上可用的硬件和软件，标准的实验室调查适应了认知科学的教学方法。同样的微型计算机被用作测量仪器、分析工具、图形显示单元、作业记录库和教学辅助工具。通过标准的假设检验程序评估教学效果。研究结果通过标准出版渠道、为当地高中物理教师举办的讲习班以及最终的暑期学生讲习班进行传播。
