RESUMO
Techniques in Molecular Biology is an essential course designed for postgraduates majoring in medicine,biology and other related disciplines.We discussed here the significance of redesigning and the practical attempt,which specifically was the flip classroom model of research-based experimental course dominated by postgraduates.In this teaching model,according to the procedure of research work,postgraduates studied the experiment principle,read kit manual and selected controls before class.In the class,students in groups performed experiments and analyzed the experimental results.The teacher led students' technical operation to achieve the teaching targets and emphasized the evaluation for students' abilities of experimental design and results analysis.Online platform was maintained even after the course in order to achieve long-term academic communication.
