《数学课程标准》明确指出:“有效的数学活动不能单纯地依赖模仿与记忆,动手实践,自主探索与互助交流是学习数学的重要方法。”可见,互助学习是数学学习的重要手段之一。互助学习不仅可以更好地促进学生之间的交流和共同进步,而且能够很好地调动学生学习的积极性、主动性,提高课堂教学效率。因此,在平时的课堂教学中,作为教师应 “Mathematics Curriculum Standard” clearly states: “Effective mathematics activities can not simply rely on imitation and memory, hands-on practice, independent exploration and mutual exchange is an important way to learn math.” It can be seen that mutual aid learning is an important means of math learning one. Mutual aid learning can not only promote the exchange and common progress among students better, but also can arouse the enthusiasm and initiative of students and improve the efficiency of classroom teaching.
