化学是一门以实验为基础的自然学科,实验在教学中占有十分重要的地位。初三学生的思维正处在以形象思维为主向抽象思维转变的过渡阶段,他们知识的获得,在很大程度上有赖于感性材料的配合,他们对通过日常生活经验、实验现象抽象出来的概念、理论较易理解。但是,化学教材对化学实验中环保教育体现得很少,导致教师讲化学实验时也强调得少,学生在实验过程中就更加不重视环保教育。从本质上说,环保教育就是一种生存教育,保护环境,就是保护我们自己,应该引起大家的足够重视。
Chemistry is a natural science based on experiment. Experiments occupy a very important position in teaching. The third grade students’ thinking is in the transitional stage from the change of the image thinking to the change of the abstract thinking. Their acquisition of knowledge depends largely on the cooperation of the sensuous materials. Their knowledge of the daily life experience and the experiment phenomenon are abstracted Concept, theory easier to understand. However, the teaching materials of chemistry show little environmental education in chemical experiments, which leads teachers to emphasize less when they talk about chemistry experiments. Students even pay less attention to environmental education in the experiment. In essence, environmental education is a kind of subsistence education. To protect the environment is to protect ourselves and should draw enough attention from everyone.
