边讲边实验是根据教材和教学进度,结合教师讲课过程中的有关内容,一般由学生1—2人为一组,应用一定的仪器和药品,在课内由学生自己动手实验,通过观察实验现象和问题讨论的形式,达到形成概念和理解化学知识的目的。边讲边实验是化学实验教学中一种重要的教学手段,这已为很多化学教师和研究人员所证实。因为由学生亲自动手实验、观察、分析得出结论,得到十分深刻的印象。同教师的演示实验相比较,实验过程可见度大,对培养学生的观察能力和
The lectures are based on the teaching materials and teaching schedules, combined with the relevant contents of the teacher’s lectures. Generally speaking, students are a group of 1-2 students, apply certain instruments and drugs, and hands-on experiments are carried out by the students themselves during the lesson. In the form of discussion with questions, the purpose of forming concepts and understanding chemical knowledge is achieved. The lectures are an important teaching method in chemistry experiment teaching. This has been confirmed by many chemistry teachers and researchers. This is because the students’ hands-on experiments, observations, and analysis have led to a very deep impression. Compared with the teacher’s demonstration experiment, the experimental process is highly visible, and it has the ability to observe and train students.
