Restructuring an Introductory Electricity, Magnetism and Optics Laboratory

物理学(13)。这个项目使用教育研究的结果来重新设计导论电学和磁学(E&Amp；M)实验室的实验。电磁相互作用和光在确定物理世界的结构方面发挥着核心作用，在现有和新兴技术中也很重要。理工科学生有必要对电子与机械有基本的了解，传统上，这类学生会在物理入门课程的后半部分学习这方面的知识，这一建议的智力优势包括基于预测、观察、解释方法的新实验，这种方法要求学生首先测试假设并预测特定实验的结果，然后再进行测量。带有实验室接口的计算机可以实时记录和绘制物理量。这两个因素使学生能够积极面对困难的概念，解决以往对电学、磁学和光学的误解，从而显著提高实验教学的有效性。该项目的有效性是通过使用标准工具的学生表现来评估的，并在每学期从学生评估中获得额外的信息。这使得可以将学生的总体满意度和表现与现有实验室的十年信息数据库进行比较。与同事和社区分享更广泛的影响。

Physics (13). This project uses the results of educational research to redesign experiments in the introductory electricity and magnetism (E & M) laboratory. Electromagnetic interactions and light play a central role in determining the structure of the physical world and are important in existing and emerging technologies. A basic understanding of E & M is necessary for science and engineering students and traditionally such students study this in the second half of the introductory physics course, the intellectual merit of this proposal includes new experiments that are based on a predict, observe, explain approach that asks students to first test hypotheses and predict the outcome of a particular experiment before making measurements. Computers with laboratory interfaces allow real-time recording and graphing of physical quantities. These two factors allow students to actively confront difficult concepts and resolve prior misconceptions about electricity, magnetism and optics resulting in significant improvement in the effectiveness of laboratory instruction. Effectiveness of the project is evaluated by student performance using standard instruments with additional input from student evaluations each semester. This allows comparison of student overall satisfaction and performance with a ten year data base of information from the existing laboratory. Broader impacts are shared with colleagues and the community.
