传统的化学实验教学由于受实验材料、实验装置及实验方法的限制,化学实验往往被固定在教室或实验室,而且以演示实验为主,教师做,学生看,实验只起着验证知识和结论的作用。学生在被动中接受,没有探究,没有发现,没有乐趣,创新意识逐渐被扼杀。在课程改革的今天,必须改变这种现状,充分发挥实验探究功能,注重学生自主实验,拓宽实验渠道,让学生学会发现问题和解决问题。在教学实践中,我总结出引导学生进行自主化学实验的五个环节,收效较好。
Due to the limitations of experimental materials, experimental devices and experimental methods, the traditional chemical experiment teaching is often fixed in the classroom or laboratory, and the demonstration experiment is the main task. The teacher does the experiment and the student only plays the role of verifying the knowledge and conclusion Role. Students are passive, no inquiry, no discovery, no pleasure, and the consciousness of innovation is gradually stifled. In the course of curriculum reform, we must change this situation, give full play to the function of experimental inquiry, pay attention to students’ independent experiments, broaden the experimental channels and enable students to learn to discover and solve problems. In teaching practice, I have summed up the five links guiding students to carry out independent chemistry experiments, and achieved good results.
