聋校高中数学函数教学的策略探讨

A Discussion on the Strategy of Mathematical Function Teaching in Senior High Schools for the Hearing-impaired Students

函数是聋校高中数学的重要内容,函数的观点与方法贯穿整个聋校高中数学教学。在每年的聋人高考单招考试中,函数是数学命题的重点和热点。聋生由于听力缺损造成语言发展迟缓,抽象思维能力水平较低,在函数教学中存在各种问题,须从完善知识点衔接,重视思想方法渗透,信息技术与教学融合等方面提高聋校高中函数教学水平,提升数学素养。

Function is an important part of mathematics in senior high schools for the hearing-impaired students,which has always been the key point and hotspot of mathematics tests in the annual college single-entry examination for the deaf people.Since the deaf students have slow language development and low level abstract thinking ability due to their hearing impairment,there are various problems in function teaching,such as improving the connection of knowledge points,emphasizing the penetration of thought,improving the function teaching level with the integration of information technology and classroom teaching,and improving the mathematics literacy.
