This project supports a major reorganization of the laboratories for the second half of the introductory physics sequence for all science majors and pre-engineers (approximately 80 students each year). This continues the restructuring, begun in 1990, of the introductory laboratory sequence for these majors. The department is organizing four laboratory modules, Wave Motion, Electricity and Magnetism, Optics, and Modern Physics, each requiring 3 to 4 weeks to complete. Each module contains several innovative experiments that are run weekly until the module is completed by all of the students. This arrangement reduces the number of setups for an individual experiment, resulting in significant cost reductions to the university and its sponsors. This project specifically addresses Module 2, Electricity and Magnetism. Classic experiments have been merged with new approaches to introduce the student to the concepts of exponential decay in physical situations, behavior of pulses in transmission lines, and experimental determination of fundamental constants. The exercises encourage creative curiosity and rely heavily on the use of analytical techniques made possible by computers. The module represents a more loosely structured laboratory than the conventional approach in which everyone does the same experiment at the same time. The involvement of the students in discussions with one another and the enhancement of creative curiosity should occur more readily in a less structured environment. The project uses student focus groups, survey instruments, and observations in formative and summative evaluation. Dissemination products include course materials, software, a laboratory manual, and final evaluation reports.

该项目支持对所有理科专业学生和预科工程师(每年约80名学生)物理入门课程后半部分的实验室进行重大重组。这延续了从1990年开始的这些专业的入门实验室顺序的重组。该系正在组织四个实验模块，即波动运动、电磁场、光学和现代物理，每个模块都需要3到4周的时间来完成。每个模块都包含几个创新实验，每周运行一次，直到所有学生完成该模块。这种安排减少了单个实验的设置数量，从而显著降低了大学及其赞助商的成本。本项目具体涉及模块2，电和磁。经典实验与新方法相结合，向学生介绍物理情况下的指数衰减、传输线中脉冲的行为以及基本常数的实验测定的概念。这些练习鼓励创造性的好奇心，并在很大程度上依赖于计算机所带来的分析技术的使用。该模块代表了一个比传统方法更松散的实验室，在传统方法中，每个人都在同一时间进行相同的实验。在结构较差的环境中，学生更容易参与彼此的讨论并增强创造性的好奇心。该项目在形成性和终结性评估中使用了学生焦点小组、调查工具和观察。传播产品包括课程材料、软件、实验室手册和最终评估报告。
