大学物理设计性实验教学分析——以“不同方法测量三棱镜的折射率并拟合其色散曲线”为例

Analysis of Designed Experiment Teaching in University Physics——An Example of“Measuring the Refractive Index of a Prism by Three Methods and Fitting Its Dispersion Curve”

基于目前大学物理实验教学中所呈现出的教学模式保守、教学内容陈旧、教学方法呆板、考评方式单一等问题,设计了不同方法测量三棱镜的折射率并拟合其色散曲线的设计性物理实验。介绍了实验题目选择、实验方案设计、实验操作实施、实验过程汇报、实验论文撰写等设计性物理实验开设的全过程以及考评方式。设计性教学方式的运用成功激发了学生的学习兴趣与探索精神,培养学生的创新思维以及科研能力,提高了实验教学质量。

Because of the problems of conservative teaching mode,outdated teaching content,rigid teaching methods,and single evaluation method in the current college physics experiment teaching,we take the experiment of measuring the refractive index of a prism with different methods and fitting its dispersion curve as an example to solve the problems.In this paper,we introduce the whole process and evaluation methods of designing physics experiments in detail,such as the selection of experimental subjects,the design of experimental schemes,the implementation of experimental operations,the reporting of experimental processes,and the writing of experimental papers.The application of design teaching method has successfully stimulated students’learning interest and exploration spirit,cultivated students’innovation and scientific research ability,and improved the quality of experimental teaching.
