课堂是教师传授知识和学生学习的主要阵地,课堂效率的高低直接影响着教师教的质量和学生学的效果。随着教学改革的进一步深化,如何构建高效的数学课堂成了诸多数学教师关注的焦点。所谓的高效课堂,就是以最小的投入让学生获得最大的收益。那么教师如何在有限的45分钟里,完成数学知识点的传授,并让学生全面掌握知识点就是高效课堂要解决的关键问题。 Classroom is the main position for teachers to impart knowledge and students’ learning. The level of classroom efficiency has a direct impact on the quality of teachers’ teaching and the effect of students’ learning. With the further deepening of the teaching reform, how to construct an efficient math classroom has become the focus of many math teachers. The so-called efficient classroom, is to minimize the input for students to maximize the benefits. So how the teacher in a limited 45 minutes to complete the teaching of mathematical knowledge points, and to allow students to fully grasp the knowledge point is the key issue to be solved in an efficient classroom.
