Abstract:

The question “whether Dll4 extracellular domain can inhibit endothelial cells angiogenesis” is probed to discuss the application of PBL incorporated with flipped classroom teaching model in medical molecular biology experimental teaching. Different from the traditional teaching which separates theory and experiment of molecular biology apart, this teaching model organically integrates a variety of common molecular biology experimental techniques such as DNA extraction, PCR, nucleic acid electrophoresis, and gel recovery by engaging students to solve a scientific problem. On one hand, it strengthens the practical application of the techniques. On the other hand, combination of PBL with flipped classroom teaching model can further enhance students’ enthusiasm and subjective initiative in knowledge exploration, and ultimately achieve practical improvement of students’ scientific research ability to discover, analyze and solve problems.

Key words: PBL teaching method, flipped classroom, molecular biology, experimental teaching, teaching model
