备课的功能主要有:实施教学的先导性功能;评价教学的反思性功能;自身提高的激励性功能;设计策略的服务性功能;知识管理的创新性功能。在化学学科备课中,为了实施这些备课功能就很有必要研究备课的策略。《化学备课的功能与策略》一文就这些问题进行了有益的探讨,对广大化学教师提升专业素养,给予了一定的理性支持。 The main functions of lesson preparation are: the implementation of the teaching of the pilot function; evaluation of reflective teaching function; self-improvement of the incentive function; design strategy service function; knowledge management of innovative features. In chemistry lesson planning, in order to implement these lesson planning functions, it is necessary to study the lesson preparation strategy. The article “Function and Strategy of Chemical Preparatory Course” explores these problems in a beneficial way, and gives certain rational support to the majority of chemistry teachers in enhancing their professional accomplishments.
