Talking About the Design and Practice of Micro-lessons in Biochemistry: Taking Vitamin A and Human Health as an Example

Abstract

Objective To explore the characteristics of "micro-lessons" production in biochemistry, to find teaching mode suitable for medical education and teaching characteristics in the Internet era. Methods Taking "Vitamin A and Human Health" as an example in biochemistry to explore the characteristics of micro-lessons in biochemistry. 400 students of clinical medicine undergraduate in Grade 2016 were selected and randomly divided into 2 groups by cluster sampling method. The micro-lessons teaching model was applied in the control group of 200 students in 1-4 classes, while the traditional teaching mode was applied in the experimental group of 200 students in 5-8 classes. And randomly selected 100 students in the experimental group, we survey the strengths and weaknesses of micro-lessons in biochemistry from the micro-lessons production, knowledge memory learning and theoretical practice and other aspects of the questionnaire. Results The scripts were designed carefully and the materials were dealt with reasonably. The micro-lessons were completion of production successful. The score of the test results [9.52 ± 0.56] in the experimental group was higher than that of the control group [8.73 ± 0.39] (p = 0.00), the difference was statistically significant. In the eight indicators, the teaching method is endorsed by most students. Conclusion The micro-class in Biochemistry can expand learning time, with repeatability, break the traditional teaching deficiencies. To adapt biochemical reform requirements in the network environment curriculum, it is worth in other professional basic courses to try.
