聋哑儿童数学能力分析

Basic mathematical competencies of children with hearing-speech impairment

目的比较聋哑儿童与普通儿童间数学能力的差异,为聋哑儿童数学教育方法的改进提供依据。方法随机抽取聋哑小学生59名,按1∶2选取118名普通小学生作为对照,采用"中国小学生数学基本能力测试量表"进行测试。结果两组儿童在加法、减法、乘法、除法、填空、比较大小、续写数字、目测长度、图形计算、数字连接等项目上得分差异有显著性(P<0.05),普通儿童均分高于聋哑儿童。结论聋哑儿童在数学运算及空间-视觉能力方面较普通儿童低。聋校数学教育的关键在于创设合适的数学学习情景,帮助学生由直观思维过度到抽象思维。

[Objective] The mathematical abilities between elementary students with and without hearing-speech impairment were compared to provide the basis of improving teaching plan to children with hearing speech impairment. [Method] 59 children with hearing-speech impairmentand 118 normal pupils selected by 1 ： 2 paired measures were assessed with ＂Chinese Rating Scale of Basic Mathematical Competencies of Elementary StUdents＂. [ Result] Average scores of children with hearing speech impairment were significantly lower than those of normal children in addiction, subtraction, multiplication, division, filling vacancies, comparing figures, extending figures, eyeballing length, accounting pictures,connecting figures（P〈0.05）. [Conclusions] The arithmetic and space-visual competencies of children With heating speech impairment are poorer than those of normal children. The key of teaching children with hearing-speech impairment mathematics is creating appropriate mathematics study scenes ＇to help＇ them to convey straight thinking into abstract thinking.
