Restructuring an Introductory Electricity, Magnetism and Optics Laboratory

物理(13)。本计画利用教育研究的结果，重新设计电磁学导论实验室的实验。电磁相互作用和光在确定物理世界的结构中起着核心作用，在现有和新兴技术中都很重要。对于理工科学生来说，对E &amp； M的基本理解是必要的，传统上，这些学生在物理导论课程的后半部分学习这个，这个建议的智力价值包括基于预测，观察，解释方法的新实验，要求学生在进行测量之前首先测试假设并预测特定实验的结果。具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地面对困难的概念，并解决先前对电、磁和光学的误解，从而显著提高实验室教学的有效性。该项目的有效性是通过使用标准工具以及每学期学生评估的额外输入来评估学生的表现。这样可以将学生的总体满意度和表现与现有实验室的十年数据库信息进行比较。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.
