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。动手操作是学生参与学习、获得知识的必要手段,是智力的起源,是思维的基础。在数学教学理念日益更新的课程改革实践中,教师要创设既合理又富有活力的学习情境,有效地进行数学课堂教学。 Effective mathematical learning activities can not simply rely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange is an important way for students to learn mathematics. Hands-on operation is a necessary means for students to participate in learning and acquire knowledge. It is the origin of intelligence and the basis of thinking. In the practice of curriculum reform, which is more and more updated in the philosophy of mathematics teaching, teachers should create a learning situation that is both reasonable and dynamic, and effectively carry out mathematics classroom teaching.
