Application of JiTT model in comprehensive experimental teaching of biochemistry / 中华医学教育探索杂志

ABSTRACT

Objective To explore the method and effect of applying just-in-time-teaching (JiTT) mode in the reform of the teaching method of biochemical comprehensive experiment (Isolation, Purification and Identification of γ-Globulin From serum). Methods A total of 100 undergraduate students in our 2016 clinical medicine were divided evenly into two groups the control group and the experimental group. The control group used traditional teaching, and the experimental group used JiTT-based teaching. In the experimental group, an online environment for pre-classroom discussion and feedback was constructed by uploading learning resources such as short video and tutorials to the online teaching platform and the online learning exchange group 3-5 days before the class; the class session itself consisted of personal tests, face-to-face teaching by teachers, group discussion, finishing experimental report and answering questions etc., and was intended to evaluate the students' self-study. SPSS 22.0 was used to collect exam scores and questionnaire results, and the data between groups were compared using t test. Results The scores of individual test scores in the experimental group (9.44±0.59) were higher than those in the control group (8.77±0.41) (P=0.00), and the difference was statistically significant. In all the six questionnaire items pertaining to teaching effect , JiTT teaching method received higher scores than the traditional teaching method (P<0.05), and the difference was statistically significant. Conclusion JiTT can improve the quality of biochemistry experiment teaching. It is worthwhile to try it in the teaching of other basic specialized courses.
