化学是以实验为手段来研究物质及其变化的科学,是以观察物质及其变化为特征的。多年来,我在化学教学中,从不放松实验教学,最大限度地挖掘实验潜力,培养学生观察能力和探索化学实验的精神,激发学生学习化学的兴趣,起到事半功倍之效,下面谈谈在实验教学中如何培养学生的观察能力。一、指导学生观察实验目的要明确由于初中生对化学实验有着强烈的兴趣和好奇心,为增强学生的感性认识,课本中的实验明显伴随现象较多,所以教师在教学中一定要让学生明确实验的目的,使学生了解应该观察什么,从哪些角度去观察。比如:我们做的铁
Chemistry is a science that uses experiments as a means of studying matter and its changes, characterized by the observation of matter and its changes. Over the years, in chemistry teaching, I never relax the experimental teaching, to maximize the experimental potential, to develop students’ ability to observe and explore the spirit of chemical experiments, to stimulate students interest in learning chemistry, play a multiplier effect, the following talk How to Train Students’ Observation Ability in Experiment Teaching. First, to guide students to observe the purpose of the experiment should be clear As junior high school students have a strong interest in chemistry experiments and curiosity, in order to enhance students’ perceptual knowledge, textbooks in the experiment with the obvious phenomenon, so teachers in teaching must make students clear The purpose of the experiment, so that students understand what should be observed from what perspective to observe. For example: we do iron
