“提问”是课堂教学中用来启发学生思考的一种好方法。它可以促使学生集中注意去思考某个方面的问题,从而加深对物理概念和规律的理解。“提问”虽然大家都在用,但用法、要求各不相同,效果也就不一样。我认为提问应面向全体学生。所提问题要有一定的思考性并且能引起同学的兴趣。要尽可能避免不用思考立即回答的“是不是”、“对不对”的问题。例如,在初中讲过光的反射定律之后,为了检查学生对定律的掌握情况,可有如下三种不同的发问:1)什么是光的反射定律?2)光的反射定律的内容是什么?3)给你一个沙盘、三根竹签,请用竹 “Questioning” is a good way to inspire students' thinking in classroom teaching. It can motivate students to focus on one aspect of a problem, thereby deepening understanding of the concepts and laws of physics. Although we are all using questions, the usage and requirements are different, and the effects are different. I think the question should be for all students. The questions raised must have some thinking and can arouse the interest of the students. To avoid as far as possible without thinking immediately answered the “yes”, “right” problem. For example, in the junior high school after talking about the law of reflection of light, in order to check the students grasp of the law, there are three different questions as follows: 1) What is the law of light reflection? 2) What is the law of light reflection? 3) Give you a sand table, three bamboo sticks, please use bamboo
