随着社会的进步和科技的发展,学生的接触面越来越广,获得的知识也越来越丰富。在课堂上,他们不会仅仅满足于课本上的知识,而是常常会出其不意地提出一些小问题,这些问题看起来很不起眼,但是,如果教师处理不当的话就会影响学生的学习兴趣。因此,对于课堂突发问题不能随意处理。 With the progress of society and the development of science and technology, the contact area of ​​students is getting wider and wider, and the knowledge gained is getting richer and richer. In the classroom, they are not content with textbooks. Instead, they often come up with some minor questions which may seem obscure.
