加强实验教学,是培养学生的动手、观察、推理能力和提高化学教学质量的重要手段。为加强实验教学,我曾作以下三方面努力,且取得了较好的教学效果。一、恰当地安排实验课本中每个实验都有明确的目的,我在认真分析之后,将实验分四种情况安排。1.凡学生凭借已有知识能判断出实验现象和结果的,可采取先分析后实验的办法。如对高一学生讲浓硫酸的特性时,是先带领学生回忆初中学过的
Strengthening experimental teaching is an important means to cultivate students' ability of starting, observing, reasoning and improving chemistry teaching quality. To strengthen the experimental teaching, I have made the following three efforts, and achieved good teaching results. First, the proper arrangement of the experimental textbook Each experiment has a clear purpose, I carefully analyzed, the experiment is divided into four situations. 1. Where students can rely on the existing knowledge to determine the experimental phenomena and the results, can take the first analysis after the experiment approach. As a freshman to talk about the characteristics of concentrated sulfuric acid is to lead students to remember junior high school memories
