《全日制义务教育数学课程标准》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”。在探究性学习中,有计划、有组织的小组讨论是一种好方法。讨论中,学生动口、动脑,相互启发,取长补短,探究机会增多,有利于培养学生学习的主动性。 The “Full-time Compulsory Education Mathematics Curriculum Standards” pointed out that “effective mathematics learning activities cannot simply rely on imitation and memory, and hands-on practice, independent exploration and cooperation and communication are important ways for students to learn mathematics.” In inquiry learning, planned and organized group discussions are a good way. During the discussion, students are motivated and brain-motivated to learn from each other, learn from each other and increase their chances of inquiry. This is conducive to cultivating students’ initiative in learning.
