化学是一门实验科学。传统的课堂教学在给学生提供感性材料方面有很大的局限性。有时由于未能给学生形成必要的表象,影响学生对知识的理解和巩固;再者传统的课堂教学使有的学生“吃不饱”,有的学生“吃不了”,尖子学生被抑制,差生跟不上,两极分化加剧。另一方面是教师花在批改作业等工作上的时间太多,影响钻研业务。我们认为,要解决这些问题必须发展电化教育。 第二次世界大战期间,美国利用电化教育训练军队,培养技术人员,取得了很大的成绩,
Chemistry is an experimental science. Traditional classroom teaching has great limitations in providing students with emotional materials. Sometimes it fails to give students the necessary appearances, which affects the students’ understanding and consolidation of knowledge. In addition, traditional classroom teaching enables some students to “eat up” and some students “can’t eat”. The top students are suppressed and poor students are born. Failing to keep up, polarization has increased. On the other hand, teachers spend too much time on the job of correcting assignments, affecting the study business. We believe that in order to solve these problems, we must develop e-education. During the Second World War, the United States made use of e-education to train the military and train technicians and achieved great results.
