在化学教学实践中,应该体现列宁的认识论即“由生动的直观到抽象的思维,再由思维到实践”这一原则。因此不管教师采用哪一种实验教学法,都必须重视促进学生的思维,将生动的直观和抽象的思维有机地结合起来。要达到这一目的,我的体会是:首先,在进行实验时,不仅要教会学生正确地观察,同时还应引导他们运用看到的事实进行思考,使能从感性知识的积累达到理论上的概括。如研究单质溴的性质时,我让学生观察盛有少量溴水和液体溴的试 In chemistry teaching practice, we should reflect Lenin’s epistemology: “from vivid intuition to abstract thinking, then from thinking to practice.” Therefore, no matter which kind of experimental teaching method is adopted by teachers, we must attach great importance to promoting students’ thinking and organically combining vivid visual and abstract thinking. To realize this goal, my experience is: First of all, when conducting experiments, we should not only teach the students to correctly observe them, but also guide them to think in terms of what they see and enable them to reach the theoretical level from the accumulation of perceptual knowledge Summarized. When studying the properties of elemental bromine, I asked the students to look at the test that contained a small amount of bromine and liquid bromine
