《课程标准》指出,学生不仅应学习物理知识和技能,还应经历一些科学探究过程,学习科学方法.在实验教学中,老教师都有这样的体会:课堂上实验前的问题讨论时间往往比实际做实验用的时间多,甚至课堂上的临时性实验教学“生成点”会影响整个课堂结构;有时虽然能在课堂完成原先制定 The “Course Standard” pointed out that students should not only learn physics knowledge and skills, but also should undergo some scientific inquiry process and learn scientific methods. In the experimental teaching, the old teachers all have this experience: the problems in the classroom before the experiment are often discussed There are many practical experiments, and even temporary teaching “generating points” in the classroom will affect the entire classroom structure; sometimes they can be completed in the classroom.
