近几年,在数学课堂教学中,存在一种形式主义的倾向,导致课堂教学的低效。本文通过几个教学案例,谈谈提高数学课堂教学有效性应注意“三结合”。一、数学活动:动态与静态相结合课堂上我们要创设生动有趣活泼的情境,让学生经历观察、实验、猜测、验证、推理与交流、问题解决等思维实践活动,做到动中有静,静中有动;动而不乱,静而不呆;动静交替,有张有弛,在启发学生展开数学思维上做文章,因为“数学教学是数学思维活动的教学”。案例1:人教版三年级下册“求平均数”教学片断。
In recent years, there has been a formalist tendency in mathematics classroom teaching, which has led to the inefficiency of classroom teaching. This article through several teaching cases, to talk about improving the effectiveness of teaching in mathematics should pay attention to “triple combination ”. First, the mathematical activities: the combination of dynamic and static We should create a lively and interesting classroom situations, so that students experience observation, experiment, speculation, verification, reasoning and exchange, problem solving and other thinking practice activities, Static and dynamic; dynamic and not chaos, static and not stay; static and dynamic alternation, there Zhang relaxation, to inspire students to start thinking about mathematics to make an issue, because “Mathematics teaching is the teaching of mathematical thinking activities ”. Case 1: PEP third grade volumes “average” teaching pieces.
