Abstract:
Objective:To investigate the application effect of the blended teaching model of "pre-class synchronous small private online course (SPOC)+ flipped classroom+post-class knowledge expansion" in the theoretical teaching of biochemistry and molecular biology. Methods:A total of 951 students majoring in clinical medicine, preventive medicine, and pharmacy in the class of 2020 in Qiqihar Medical College were selected as teaching reform research group (experimental group), and their curriculum relied on the self-built massive open online course (MOOC) curriculum and the MOOC resources of Chinese universities to construct a blended teaching model; the reform methods such as small class grouping, case-based learning, and diversified examination were adopted to carry out theoretical flipped teaching activities with cross integration of cases and knowledge points as the main line. A total of 847 students majoring in clinical medicine, preventive medicine, and pharmacy in the class of 2019 were selected as control group, and the traditional teaching method was used for theoretical courses. The courses were evaluated by offline assessment and online assessment, and feedback information was collected through examination scores, questionnaire survey, and online voting. SPSS 20.0 was used for statistical analysis, and the t-test was used for comparison between groups. Results:The experimental group had a significantly higher total score of final examination than the control group [(92.12±3.88) vs. (86.73±5.27), P<0.05]. The questionnaire survey showed that the students in the experimental group showed a relatively high degree of satisfaction with the blended teaching reform, which increased their participation, experiencing, and sharing activities. The students majoring in clinical medicine in the class of 2020 believed that they had established clinical thinking ability (263, 92.61%) and become familiar with the clinical manifestations and pathogenesis of common diseases (262, 92.25%); the students majoring in preventive medicine in the class of 2020 believed that they had increased their awareness of serving the public (151, 93.21%) and developed the ability to teach and guide healthy living (148, 91.36%); the students majoring in pharmacy in the class of 2020 believed that they had mastered the mechanism of action of drugs for disease treatment (138, 93.24%) and understood the importance of rational drug use in clinical practice (135, 91.22%). Conclusion:The blended teaching model realizes student-centered teaching, stimulates the interest and initiative in learning, and improves learning outcome, thereby improving teaching quality to a certain extent.
