Abstract:

The current training of pre-service teachers suffers from the low percentage (20%) of PCK from students themselves, low teacher-to-student ratio, short schooling terms, less teacher-student interactions, less practice courses offered, and little practice time. In this regard, our work begins with improving normal university students' PCK (ontological knowledge, conditional knowledge, practical knowledge). The practice uses the double guide system (mentoring and peer-leading) as the main tool to explore effective culture model for chemistry-majoring normal university students. In the innovation, three practice modes, teaching design-based simulation, observing the activities of teaching, and trainee teaching under real-life situation, have been adopted to enhance the training.

Key words: Chemistry, Tutorial system, Tutor system, PCK, Excellent teachers
