数指法在聋校低年级数学教学中的应用价值及实施方式

Value and Methods of Counting on Fingers in Low-grade Math Teaching in Deaf Schools

数手指计算是聋生在学习数学之初的自发、自然行为。儿童利用手指认数和计数,类似于学具操作,数指过程不仅是聋生计数、计算的过程,更是聋生使用手语学习和思维的过程,使用数指法能帮助聋生度过数学学习之初的难关。聋校数学教学应顺应聋生的这一认知特点,设计出一套符合聋生学习特点的数指方法,指导聋生使用手指科学地进行计数、计算,不断提高数学学习水平。

Counting on one＇s fingers is a spontaneous and natural behavior at the beginning of learning mathematics of the deaf students. Children use their hands to know and count numbers,similar to operate learning tools. The process of counting fingers is not only the process of counting and calculating process of the deaf students,but also a process of learning and thinking via dactylology,helping the deaf student to overcome difficulties at the beginning of learning mathematics. The mathematics teaching of the deaf schools should conform to this cognition feature and design a methodology of counting fingers suitable to the learning characteristics of the deaf students to guide them using their fingers to count and calculate scientifically and improve their proficiency levels of mathematics continuously.
