化学概念是将化学现象、化学事实经过分析、比较、综合、归纳等思维活动抽象概括出来的理性知识,是化学科学发展的智慧结晶。概念作为思维的细胞,在化学知识网络中扮演着“结点”的角色,只有在充分理解化学概念的基础上,学生才能形成化学知识网络。为此,教师们普遍将化学概念教学视为提高化学教学质量的关键所在。但传统的化学概念教学存在着重记忆、轻理解的弊端,强调学生对概念定义的识记,忽视概念间联
The concept of chemistry is a rational crystallization of chemical science, which has been abstractly summarized through analysis, comparison, synthesis and induction of chemical phenomena and chemical facts. The concept of thinking as a cell in the chemical knowledge network plays a “node ” role, and only on the basis of full understanding of the chemical concept, students can form a chemical knowledge network. For this reason, teachers generally view chemistry concept teaching as the key to improving the quality of chemistry teaching. However, the traditional teaching of chemical concept has the defects of memory and light comprehension, emphasizing the students’ recognition of the concept definition and neglecting the conceptual connection
