从中美小学生数学学习的多元表征看数学教学

Mathematics Teaching Based on Multi-Representations of Chinese and U. S. Primary School Mathematics Learning

中美小学生学习成就得益于不同表征的使用。多元表征利于学生数学思维和创新能力的发展。在中国数学课堂教学中，应该以直观表征引入数学概念，多元表征变式加深数学理解，引导学生自己创建多元表征。

Chinese and U. S. pupils' learning achievements benefits from the use of different representations. Multi- representations can be conducive to the development of students' mathematical thinking and innovation ability. In mathematics classroom teaching involved multi- representation，mathematical concepts should be introduced through visual representation，mathematical understanding should be deepened through multi- representation's variation，students should be guided to create multi- representations for themselves.
