课堂提问是教师常用的一种教学手段;是教师获得反馈信息的重要途径;是促使学生积极思考的主要途径和方法;对检查学生的学习情况、提高学生的思维能力具有显著的作用。随着素质教育的改革深入和发展,提问在课堂教学中扮演着越来越重要的角色,因此数学课堂的提问的有效性得到越来越多教师的重视。课堂提问在我们每节数学课中都是存在的,但是反思起来觉得有时自己的提问是有效的有时是无效的。很多老师的课堂提问的有效性得不到保证,导致课堂效率降低,教学目标无法实 Classroom questioning is a kind of teaching method commonly used by teachers; it is an important way for teachers to get feedback information; it is the main way and method to encourage students to think positively; and it plays a significant role in checking students’ learning situation and improving their thinking ability. With the deepening and development of the reform of quality education, questioning plays an increasingly important role in classroom teaching. Therefore, more and more teachers pay more attention to the validity of questioning in mathematics classroom. Classroom questions are present in every math class in our class, but in retrospect sometimes it is ineffective to ask questions of their own. Many teachers can not guarantee the validity of the class questions, resulting in the decrease of classroom efficiency and the lack of teaching objectives
