《数学课程标准》中指出:“有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式”。可以看出有效教学的前提和基本目标是改善学生的学习方式,促进学生有效学习。小学生在数学学习中一般不会认真思考和分析,思维较为单一,也就是缺乏自己的思想与方法。小学数学教师应根据实际情况指导学生掌握实用而有效的学习方法。 According to “Mathematics Curriculum Standard”: “Effective mathematics learning activities can not rely solely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange is an important way for students to learn mathematics.” It can be seen that the prerequisite and basic goal of effective teaching is to improve the learning style of students and promote the effective learning of students. Pupils in mathematics learning generally do not seriously think and analyze, thinking is more single, that is, lack of their own ideas and methods. Primary school mathematics teachers should guide students according to the actual situation to master practical and effective learning methods.
