培养聋生数感 优化聋数课堂

On Training a Deaf Student’s Number Sense

数感作为新时期义务教育阶段数学课程中的全新的重要内容,是聋生对数和数的关系的一种良好的直觉,在他们对数的充分感知、感应和感受之中。随着新一轮课程改革的推进,笔者尝试研究发展学生数感的有效方法,于操作中生成,于情境中体验,于合作中强化,于应用中升华,进而优化聋校的数学课堂。

Number sense is a kind of better intuition of the deaf on the relationships of numbers and it is the important new content of Mathematics.With the proceeding of the new curriculum reform some effective ways of researching the development of number sense are attempted by operating,experiencing,cooperating and applying to optimize Mathematics classes in school for the deaf.
