课堂教学是学生在校获取知识的主要途径。在当今课程改革的背景下,取消了早晚课,使学生在校时间大大减少,这在客观上也使得学生巩固练习的时间减少了,从而不可避免地面临学生对知识点把握不扎实的问题。如何在课堂教学中解决好这一问题,使得学生在有限的时间内学到有效的数学,并能学以致用,是每一位一线教师面临的共同难题。我校属于薄弱校,学生本身基础较差,这个问题就更加明显。 Classroom teaching is the main way for students to acquire knowledge in school. In the context of today’s curriculum reform, the abolition of morning and evening classes, so that students in school greatly reduced the time, which objectively also makes students consolidate the practice of reducing the time, which inevitably face the knowledge of students to grasp the problem is not solid. How to solve this problem in the classroom teaching so that students can learn effective mathematics in a limited time and learn from them is a common problem for every front-line teacher. My school is a weak school, poor students themselves, the problem is even more apparent.
