课堂教学的有效性是指在课堂教学中,教师通过多媒体或自制的教具等多种教学手段,采取有效的教学方法,提高学生的学习兴趣,发挥学生学习的主动性作用,不断提高课堂效率。本文我从四个方面分析了小学数学课堂如何实现教学的有效性。一、灵活的课程导入灵活的课堂导入语言能激发学生强烈的学习兴趣和求知欲望,使其全身心地投入到探索新知识之中。小学生年龄小,注意力不易集中,通过灵活的课堂导入在第一时间将他们的注意力吸引到学习中来可以极大的提高教学效 The effectiveness of classroom teaching means that in classroom teaching, teachers adopt effective teaching methods through multimedia or self-made teaching aids and other teaching methods, improve students’ interest in learning, give full play to the initiative of students and improve the efficiency of the classroom. In this paper, I analyze the effectiveness of teaching in elementary mathematics classroom from four aspects. A Flexible Course Introduction Flexible classroom introduction of language can stimulate students’ intense interest in learning and desire for knowledge so as to dedicate themselves to exploring new knowledge. The pupils are young and their attentiveness is not easy to concentrate on. As a result, they can greatly improve the effectiveness of their teaching by attracting their attention to learning through flexible classroom induction at the first time
