Review Seminar Based on CRS in Introductory Physics

Abstract

The research on the relationship between the teaching model of seminar and the learning gain of students has been a hot topic for a long time. As the Classroom Response System (CRS) is widely used in interactive teaching environments to attract students by asking questions. This paper takes electromagnetism of introductory physics as an example to study the teaching mode of review seminar based on CRS. Focusing on the necessity of review seminar based on CRS, the teaching efficiency as well as the stability of students' learning effect under this teaching mode, this paper qualitatively discusses the necessity and teaching efficiency of review seminar based on CRS, and quantifies the learning effect of students under this mode from the correct transformation of students' concept and its stability. The results show that the teaching model of seminar based on CRS is suitable for the teaching of problem sets in introductory and has high teaching efficiency. Most of the students have the right change of physics concept after the discussion with their peers, and have stable learning gain. At the end of the paper, we discuss the shortcomings of the research and looks forward to the future research direction.
