Abstract:

A new teaching model, micro-teaching, is proposed in era of information, and the new teaching design philosophy focusing on the features and the present situation of inorganic chemistry laboratory teaching, micro class platform was built by using WeChat public account to assist the classroom teaching. It solved the problem of the inorganic chemistry laboratory teaching, such as the safety training, students' preview, more contents but less lecture time, limited resource of experimental reagents, lack of the protection from toxic reagents. Through micro-teaching, experimental content diversification and demonstration operation visualization were realized. It improves students' subjective initiative in learning, strengthens their hands-on ability, standardizes the experimental procedures, facilitates students to grasp the key and difficult points of the experiment, strengthens the communication between teachers and students, meets the requirements of students at all levels, and improves the efficiency of the classroom teaching.

Key words: Inorganic chemistry laboratory teaching, Micro-teaching, WeChat public account
