集体备课是教师合作研究的一种最有效的形式,它可以充分发挥群体智慧。在集体备课时,老师之间可以就所备的知识点进行交流,再在课堂上与学生互动、交流,这是对个人备课再认识、再创造的过程,是个人备课的深化和延伸。 Collective lesson preparation is one of the most effective forms of collaborative research for teachers, which can give full play to the wisdom of the community. During the collective lesson preparation, the teachers can exchange knowledge about the prepared points and then interact and exchange with the students in the classroom. This is a process of re-understanding and recreating individual lesson preparation, which is the deepening and extension of individual lesson preparation.
