Abstract: Pedagogic college students majoring in chemistry should be equipped with not only the professional knowledge related to their subject, but also various teaching skills. Micro-teaching is a rather effective way to improve the professional skills of pedagogic chemistry students. How to make a better use of micro-teaching to cultivate excellent pedagogic chemistry graduates has also attracted increasingly wider attention. The process of cultivating professional skills of chemistry pedagogic university students through micro-teaching consists of seven parts: the learning of theoretical knowledge of micro-teaching, the watching and observing of demo video materials, the writing of micro-teaching plans, the practical training of micro-teaching, the recording of teaching videos, the analysis and feedback, the modifying and re-construction of micro-teaching plans and strategies. By analyzing the functions of micro-teaching system in the vocational skills training of pedagogic chemistry university students and how to use micro-teaching to train their vocational skills, the measures to strengthen the training of teachers' skills are suggested: the establishment of micro-course platform to improve the feedback effect; the offer of theory course of micro-teaching; the emphasis of blackboard layout design; to clarify the goal of skill cultivation; the setting of teaching situation and writing of the teaching plan in teacher’s guidance.
