数学学习材料是数学教学的基石,它直接决定着课堂教学的效益。教师要善于并合理精选具有现实性的、有意义的、富有挑战性的学习材料,让学生在充分的学习材料中达到数学内容吸收的最大化。如何追求学习材料的简洁、有效,当再次领略马冬娟老师在一所村小执教的《轴对称图形》时,内心涌起一股一吐为快的冲动,这种冲动源于简单材料后不简单的设计与运用,从 Mathematics learning materials is the cornerstone of mathematics teaching, it directly determines the effectiveness of classroom teaching. Teachers should be good at and rational selection of realistic, meaningful and challenging learning materials to enable students to maximize the absorption of mathematical content in the full learning materials. How to Pursue the Simple and Effective Learning Materials? When we once again understand Ma Dongjuan’s “Axisymmetric Graphics” in a small village teaching, there is a rush of impulse in the heart, which is not simple after simple materials From the design and application
