“元素观”是化学学习中的重要化学观念,探寻促进学生“元素观”发展的有效教学策略,是实现初中化学由传统的“知识传授为本”走向“观念建构为本”的重要途径,具有重要意义。1.促进学生“元素观”形成的教学设计基于观念构建层级知识结构。在进行教学设计时,首先,要依据课程标准的要求,对课程单元内容进行总体的审视和把握,深入挖掘“元素观”的内涵;其次,要理清具体知识、基本概念与核心 “Elements of View ” is an important chemical concept in chemistry learning, and exploring effective teaching strategies to promote the development of students “elements ” is to realize the construction of junior middle school chemistry from the traditional “knowledge Based on ”an important way, of great significance. 1 to promote students “elemental concept ” teaching design based on the concept of building a hierarchical knowledge structure. In teaching design, first of all, according to the requirements of the curriculum standards, the content of the course unit overall review and grasp, in-depth mining “elemental concept ” connotation; Secondly, to clarify the specific knowledge, basic concepts and core
