Abstract:

The core teaching content of organic chemistry is the basic theory and reaction mechanism. The difficulty of organic chemistry teaching is the teaching and learning of reaction mechanism, which has always puzzled teachers and students, respectively. The author adopted the three-stage method "teacher's guidance/student's practice/student's comprehensive explanation" in reaction mechanism teaching and learning. Firstly, teacher explains the basic theories followed by the reaction mechanism according to the books and literatures from all over the world. Secondly, let students do some exercises. The teacher arranges basic exercises for the students according to the teaching schedule. Then combine the relevant reaction mechanism, assemble the complex multi-step reaction, and ask students to deduce the reaction products according to the mechanism. Afterwards, the student must give a lecture one by one focusing on one reaction after systematically consulted the literature and materials, organized the materials to all the students and teachers respectively. After the lecture, the teacher supplemented and modified the content the student explained. It has been proved by practice that this method is convenient for students to understand the organic reaction mechanism twice the result with half the effort.

Key words: Reaction mechanism, Three-stage teaching, Comprehensive explanation
