1 问题的提出新教材与旧教材相比除了突出研究性学习之外,还有一个较为直观的区别就是在章节之后增加了许多家庭小实验。但是经调查发现,许多教师往往为节省时间而对这些小实验置之不理,不加以重视,理由是高考不会考这些。这显然与新教材的编制理念相违背,而且这样操作往往事与愿违,反而影响了教学质量,因为课外实验与课堂教学是紧密相关、相互促进的,课外实验是课内学习的延伸和扩展,它作为一种新的实验形式,为学生提供了大量动手的机会,弥补了课堂教学的不足。 1 Compared with the old textbooks, the proposed new textbooks have a more intuitive difference than the old textbooks. Many small family experiments have been added after the chapter. However, after the survey found that many teachers often save time for these small experiments ignore, do not pay attention, the reason is that the college entrance examination will not test these. This is obviously inconsistent with the concept of the compilation of new textbooks, and such operations are often counterproductive, but affect the quality of teaching, because extracurricular experiments and classroom teaching are closely related and mutually reinforcing, and extracurricular experiments are extensions and extensions of in-class learning. A new form of experiment provides students with plenty of hands-on opportunities to make up for the lack of classroom teaching.
