Effect of the Problem-Based Learning Method on Student Electroencephalograms and Microcirculatory Blood Perfusion in the Teaching of Sports Physiology

Abstract

Introduction Applying the problem-based learning (PBL) method to the teaching of sports physiology. Objective This study explored the mechanism of the PBL method to improve the interest and learning effectiveness of students. Methods Twenty male students at the Physical Education College of Hubei Minzu University were randomly divided into a PBL group (10) and a traditional teaching method group (TTM). During the test, the subjects in the TTM group sat quietly listening to the experienced teacher, while the subjects in PBL group sat quietly and participated in a 20-minute group discussion under the guidance of the experienced teacher. Transcutaneous partial pressure of oxygen (TcPO2), microcirculatory blood perfusion (MBP), and alpha- and beta-band power were monitored at the beginning of and during the test. Results The mean of the PBL-group quiz score was significantly higher than that of the TTM group. In the PBL group, the alpha power of the students decreased statistically in the F3, T3, P3, and O1 channels and the beta power of the students increased statistically in the F7, F3, T3, C3, P3, and O1 as compared to the baseline values. Conclusion PBL can be an effective learning mechanism, since the students are actively engaged in the teaching of sports physiology.
