初中阶段,化学实验教学主要是让学生学会基本操作,同时了解实验的原理。到了高中阶段,学生不但要规范实验,而且还应该具备根据实验目的自主设计实验,运用化学实验技能解决问题的能力,当然这些能力是高中三年逐步培养的。 Junior high school, chemical experiment teaching is mainly for students to learn basic operation, at the same time understand the principle of experiment. In high school, students not only have to standardize their experiments, but also have the ability to independently design experiments based on experimental purposes and use chemical experimental skills to solve problems. Of course, these abilities are gradually cultivated by high school for three years.
