《数学课程标准》留给我们最深刻的印象是:在小学数学课堂教学中,引导学生感受、理解知识产生和发展的过程,这是学生认知的需要,也是培养学生能力的需要,更是学生情感体验的需要。其中动手实践是获取知识经验与直接表象的有效手段。先请看“面积和面积单位”的一个教学片段: 师:现在请同学们用1平方分米的纸片去测量操场的面积。
The most profound impression left by the Mathematical Curriculum Standards is that in the elementary mathematics classroom teaching, guiding students to feel and understand the process of knowledge production and development is the need of students ’cognition and the need of training students’ ability. Students need emotional experience. Hands-on practice is an effective way to acquire knowledge experience and direct appearance.
