小学数学的“错误”资源,不仅可以让教师发现学生知识掌握方面的不足,也可以让教师审视自己教学方面存在的一些误区。因此,巧妙利用“错误”资源并将其转化为课堂教学资源,有利于引导学生从不同角度修正错误,提升学生的反思能力和创造性思维,从而提升数学教学的实效性。 Primary mathematics “error ” resources, not only can make teachers find that the lack of knowledge of students, but also allows teachers to examine their own teaching some of the errors exist. Therefore, clever use of “mistake ” resources and their translation into classroom teaching resources will help students to correct mistakes from different perspectives, improve students’ reflective ability and creative thinking, so as to enhance the effectiveness of mathematics teaching.
