The application and research teaching mode of TPACK in the teaching of biochemistry / 中华医学教育探索杂志

ABSTRACT

Objective To discuss the effect of the teaching mode of technological pedagogical and content knowledge in biochemistry theory teaching. Methods 400 students in 8 classes of clinical medicine undergraduate in Grade 2013 were selected and randomly divided into 2 groups. The traditional teaching mode was applied in the control group of 198 students in 1-4 classes, while the technological pedagogical and content knowledge teaching mode was applied in the experimental group of 202 students in 5-8 classes. 385 students in 8 classes of clinical medical undergraduates in Grade 2014 were selected and randomly divided into 2 groups. The control group of 189 students in 1-4 classes adopted the traditional teaching mode, while the experimental group of 196 students in 5-8 classes adopted the technological pedagogical and content knowledge teaching mode, which used the micro-lesson and network platform as learning resource superior to the flipped classroom. Flipped classroom was divided into two major learning linksextracurricular self-study and class digestion. Through the network platform the micro-lesson was presented to the learners. Learners could make self-study according to their own specific circumstances and in the classroom many activities were increased such as the mutual cooperation between the students, the students' PPT teaching, the students' questions and the discussion, and the interaction between teachers and students, etc. The results of the examinations of the two terms students of the same profession and the questionnaire were analyzed. The related data were processed by SPSS 15.0, and the data between groups were compared by t test . Results The test scores analysis showed that the individual test scores in experimental group of Grade 2013 were [(17.94±2.02) vs. (12.28±4.17)], and the individual test scores in experimental group of Grade 2014 were [(18.21 ±1.78) vs. (12.45 ±5.13)], which were obviously higher than the control group, and there was statistical significance. The final exam scores in experimental group of Grade 2013 were [(78.28±11.18) vs. (68.65±12.51)], and the final exam scores in experimental group of Grade 2014 were [(81.73 ±9.12) vs. (74.41 ±11.87)], which were obviously higher than the control group, and there was statistical significance. The results of survey showed that the students thought the teaching mode aroused their study interests while 393 (93.7%), thought the teaching mode developed their self-study ability while 357 (89.7%), thought the teaching mode beneficial to cultivating their ability of solving the problems. Conclusion The teaching mode of technological pedagogical and content knowledge is of certain signifi-cance to break the plight of the traditional teaching, inspire the students interest in learning, improve the teaching quality of biochemistry, and make for the teachers' professional development.
