教学的效果很大程度上取决于学生的参与情况,这就要求学生主动积极地学习。学必生疑,提出问题说明学生在思考,有思考才会有创新,提不出问题才是最大的问题。长期以来人们更多地关心课堂教学艺术和高效,而课后答疑的研究相对较少。回答学生的课后疑难,其实是课堂教学的延续和补充。随着时代的发展和进步,学生时教师的答疑提出了新的要求,答疑艺术也注入了新的元素,本文从一个物理教师的视角,思考这一课题。 The effectiveness of teaching depends largely on the students’ participation, which requires students to take the initiative to learn. Learning must be suspicious, put forward the problem that students think, think there will be innovation, can not mention the problem is the biggest problem. For a long time, people are more concerned about the art of classroom teaching and high efficiency, and there are relatively few studies on answering questions after class. Answer the students after-school problems, in fact, is a continuation of the classroom and supplementary. With the development and progress of the times, the teachers’ answering questions put forward new requirements and the question answering art has also injected new elements. This article from a physics teacher’s point of view, think about this subject.
