问题是数学的心脏,提问是课堂教学重要的环节,也是教师组织课堂教学的重要手段。当前,很多数学老师在课堂上的提问随意性太大,无疑而问、重复提问的现象屡见不鲜,表面上课堂师生互动频繁,但究其本质而言,学生并没有得到提升,思维能力、表达技巧更没有得到有效的锻炼,严重制约着学生的发展。因此,教师要精心研读教材,把握教材的知识要点,设计富有实效的问题,把握提问的时机,做到巧问、优问,帮助学生理清知识的脉络,促进学生深入思考,全 The problem is the heart of mathematics, questioning is an important part of classroom teaching, but also an important means for teachers to organize classroom teaching. At present, many math teachers in the classroom questions are arbitrary, no doubt asked, repeat the phenomenon of the phenomenon is not uncommon, on the surface frequent interaction between teachers and students, but in essence, the students did not improve, thinking ability, expression Skills have not been effectively exercise, a serious constraint on the development of students. Therefore, teachers should carefully study textbooks, grasp the main points of knowledge of teaching materials, design practical problems, grasp the timing of questions, make clever questions, ask questions, help students sort out the context of knowledge, and promote students’ deep thinking
