我们在化学课的教学中,突出以实验为中 心进行了一些探索和试验,效果显著。我们的 初步认识和做法是: 1 探讨以实验教学为中心的教学方法 1.实验——引导——结论的教学模式 实验,是学生获得感性知识的客观依据。 可以在教师的引导下,学生边阅读边实验,或 者是教师边讲解边实验,或者是边讨论边实 验。引导学生正确的思维,引导学生分析实验 的原理,产生现象的原因,从现象到本质,上升 到理论,并与前面的同类知识比较,概括,综 合,而得出结论。比如硝酸性质的教学,我们
In the teaching of chemistry classes, we focused on experimentation as our center and conducted some explorations and experiments with remarkable results. Our preliminary understanding and practice are: 1 Exploring teaching methods centering on experimental teaching 1. Experiment-guided-concluded teaching model Experiments are the objective basis for students to acquire perceptual knowledge. Under the guidance of teachers, students can experiment while reading, or they can teach while experimenting, or they can discuss while experimenting. Guide students to correct thinking, guide students to analyze the principles of the experiment, generate the cause of the phenomenon, from the phenomenon to the essence, to the theory, and compare it with the previous knowledge of the same kind, generalize and synthesize, and come to the conclusion. Like the teaching of nitric acid, we
