改革大型实验室导论课程:对实验物理学观点的影响

Transforming a large introductory lab course: impacts on views about experimental physics

Benjamin Pollard, H. J. Lewandowski

摘要:

实验室课程是大多数本科物理课程的关键组成部分。实验室课程通常旨在实现以下学习成果:培养学生的实验技能,让学生参与真实的科学实践,强化概念,激发学生对物理的兴趣和参与。其中一些结果可以通过科罗拉多州实验物理科学学习态度调查(E-CLASS)来衡量,这是一项基于研究的评估,旨在衡量学生对实验物理的看法。我们在科罗拉多大学博尔德分校使用E-CLASS来衡量课程转型过程中的学习成果,在这个过程中,实验物理学的观点反映在学习目标中。我们收集了600多名学生的反应,每学期从大型介绍实验室课程,无论是之前和之后实施的课程转型。虽然我们没有观察到统计学上的显着差异,在整体教学后的E-CLASS成绩的转换之前和之后,在转换的过程中,学生的反应,三个E-CLASS项目,相关的目标的转换比原来的课程更有利。

英文摘要:

Laboratory courses are key components of most undergraduate physics programs. Lab courses often aim to achieve the following learning outcomes: developing students' experimental skills, engaging students in authentic scientific practices, reinforcing concepts, and inspiring students' interest and engagement in physics. Some of these outcomes can be measured by the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS), a research-based assessment that measures students' views about experimental physics. We used E-CLASS at the University of Colorado Boulder to measure learning outcomes during a course transformation process in which views about experimental physics were reflected in the learning goals. We collected over 600 student responses per semester from the large introductory laboratory course, both before and after implementing the course transformation. While we observed no statistically significant difference in overall post-instruction E-CLASS scores before and after the transformation, in the transformed course, student responses to three E-CLASS items that related to the goals of the transformation were more favorable than in the original course.
