化学知识趣味之中充满哲理,平淡之中蕴含神奇。化学实验生动、直观、有趣,能帮助学生形成概念,获得知识、技能及提高科学探究能力。因此,我们不仅要开展培养学生观察能力和实验能力的实验,更应改进实验教学,探索实验方法,让化学实验教学多元化,这是新课程背景下教好、学好化学这门学科的最佳途径。一、改进实验的对比性对比实验又称为对照实验,是以正确的实验操作和观察的方法为基础,以实验现象为依据,除了一个可变
The knowledge of chemical knowledge is full of philosophical and plain magic. Chemical experiments are vivid, intuitive, and interesting. They can help students form concepts, gain knowledge, skills, and improve scientific inquiry capabilities. Therefore, we must not only develop experiments to cultivate students’ observation and experimental abilities, but also improve experimental teaching, explore experimental methods, and diversify chemistry experiment teaching. This is the best way to teach and learn chemistry in the context of the new curriculum. way. A. Contrasting comparison experiments for improved experiments, also known as control experiments, are based on correct experimental operations and observation methods, based on experimental phenomena, except for a variable
