设计性实验教学实践与思考--以“电表的扩程与校准”实验为例

摘要

Implementation of design experiments can improve self-learning abilities and innovation abilities of college students. Meanwhile, the design experiment is one of teaching reform emphases of college physics experiment. In order to explore the college physics experiment teaching reform, this paper taking the “expansion range and calibration of Voltmeter” for example, teaching methods, student achievement and teaching effectiveness assessment methods of the design experiment were analyzed and discussed. Teaching effectiveness analyses showed that the percentage of students of scores in 90-100,80-90,70-80,and 60-70 are respectively 26%,55%,12% and 7%.Teaching methods, student achievement assessment methods and teaching evaluation of the design experiment in this paper provides a new way to conduct college physics experiment teaching reform.%设计性实验的实施可提高大学生的自学能力和创新能力。同时，设计性实验的开设也是大学物理实验教学改革的重点之一。为了探究大学物理实验教学改革，本文以设计性实验“电表的扩程与校准”为例，对设计性实验的教学方法、学生成绩的考核方法及教学效果进行了分析和讨论。教学效果分析表明，90-100分、80-90分、70-80分、60-70分的学生人数分别占总人数的26%、55%、12%、7%。文中设计性实验的教学方法、考核方法和教学评价可为大学物理实验教学改革提供一个新的思路。
