《数学课程标准》指出:要让学生经历知识与技能的形成过程。有效的数学活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式。教师要结合课本和学生实际合理设计数据表格就是通过表格这种形式启发学生观察事物现象,捕捉某些特征,尝试估计、直觉判断,或作思维联想,并进行必要的逻辑演绎。让学生透过教师设计的这些数据领悟、体验,更好地掌握知识。
The Mathematics Curriculum Standard states: Let students experience the formation of knowledge and skills. Effective mathematical 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. Teachers should combine textbooks and students’ actual and reasonable design of data forms through the form of this form to inspire students to observe things phenomenon, to capture some of the features, try to estimate, intuition, or thinking associations, and make the necessary logical deduction. Let students understand, experience and acquire better knowledge through these data designed by teachers.
