中学化学具有四大特点:化学的形成和发展,起源于实验,又依赖于实验,是一门以实验为基础的自然科学;化学“繁”。这个“繁”实际上就反映了化学学科知识点既多又分散,并且大量的知识需要识记;化学是表象容易,应用较难;化学与其他学科的渗透较多,如数学的极限思维、平均值应用,物理的电学、力学知识等。因此,不能把学数学、物理的方法照搬来学化学,而要根据化学科的特点做好以下八个方面——观、动、记、阅、思、 Chemistry in middle school has four major characteristics: the formation and development of chemistry, which originated from experiments and relied on experiments, is a natural science based on experiments; chemical “browsing”. This “browsing” actually reflects the fact that the knowledge and knowledge of chemistry disciplines are numerous and scattered, and a large amount of knowledge needs to be memorized; chemistry is easy to display and difficult to apply; chemistry and other disciplines penetrate more, such as the limits of mathematics Thinking, application of averages, physical electrical, mechanical knowledge, etc. Therefore, we must not copy the methods of learning mathematics and physics to study chemistry. We must do the following eight aspects according to the characteristics of chemistry: observation, movement, writing, reading, thinking,
