Application of Microlecture plus PowerPoint in physiology experiment teaching

Abstract

Objective To investigate the effectiveness of Microlecture plus PowerPoint (PPT) in physiology experiment teaching. Methods The students of clinical medicine in Grade 2015 of Hubei University of Medicine were selected as the subjects. Among them, 61 students in Class 1 were studied as the control group, while 59 students in Class 2 as the experimental group. The control group adopted the traditional teaching method and required students to complete the experimental report with handwriting, while the experimental group adopted teaching method of Microlecture plus PPT. In the experimental group, students watched the microlecture for preview and could also repeat watching at any time to correct the mistakes during the operation. After class, students of the experimental group were required to complete the experiment report in the form of PPT and send it to the teacher through QQ within the prescribed time. The learning outcomes were evaluated by using descriptive analysis and t test based on the class operation, final examination and questionnaire. Results Both the average score of experiment operation and the average score of final theory exam in the experimental group were higher than those of the control group [(95.074±3.233) vs. (81.706±2.901) and (92.204±3.074) vs. (77.913±2.611)], and the differences were of statistical significance (P<0.05) . The recovery rate of questionnaire survey was 100% in the experimental group. Over 80% students thought Microlecture plus PPT could help enhance autonomous learning ability, deepen the understanding of theory and increase group cooperation ability, et al. Conclusion Microlecture plus PPT teaching can improve the teaching effect of physiology experiment teaching, which is worthy of promotion. However, it is still necessary to combine other teaching methods to achieve better teaching results. Key words: Physiology; Microlecture; PowerPoint homework
