概念是反映物质物理属性和化学变化的一般本质属性,学生形成化学概念,感知是第一要素。概念内容的具体化又是学生形成化学概念的第一个起点。教师必须紧紧依托实验教学,引导学生从直观的实验现象中,获得感性认识,培养学生形成化学概念。下面,仅就以实验教学为主要途径,培养 Concepts are general essential attributes that reflect physical properties of matter and chemical changes. Students form the concept of chemistry, and perception is the first element. The concretization of concept content is the first starting point for students to form a chemical concept. Teachers must rely on experimental teaching closely to guide students to acquire perceptual knowledge from intuitive experimental phenomena and to cultivate students to form chemical concepts. Below, we will focus on experimental teaching as the main approach.
