提高实验教学效率是一个长期而艰巨的任务。在上科学实验课时,要有效地控制学生的静与动,课前做好充分的实验准备,有针对性地抓好重点实验,通过引导学生规范化地操作,激发学生的探究积极性,给学生充足的探究空间,这样就能有效地提高实验教学效率。 Improving the efficiency of experimental teaching is a long-term and arduous task. In the scientific experiment class, we must effectively control the students ’static and dynamic, full preparation for the experiment before class, do a good job of targeted experiments, by guiding students to standardize the operation, to stimulate students’ enthusiasm for inquiry, to give students sufficient Of the exploration space, so that we can effectively improve the efficiency of experimental teaching.
