Abstract:

Aiming at the problems existing in the scientific research feedback teaching, this paper proposes a three-step scientific research feedback teaching method based on textbooks and tracking the frontier. The application of this method is introduced by taking the content of precipitation formation as an example. Firstly, it introduces the knowledge points in the textbook, the theoretical basis of precipitation generation. Then the application of precipitation method in nanomaterials synthesis is introduced, which is very common in scientific research. Finally, the details of the nucleation process in the synthesis of metal-organic skeleton materials (MOF) are discussed, which involves the frontiers of science. The method has achieved a good teaching effect, and the students' research and innovation ability has been significantly improved.

Key words: Scientific research feedback teaching, Precipitation formation, Nanomaterials, Metal organic frameworks
