由于低年级盲生的生理缺陷,使其在教学过程中,需要运用直观的手段来弥补盲生的视觉缺陷,帮助盲生提高抽象思维能力。探讨从实物直观、教具直观和语言直观等方面在低年级数学课堂中的应用,以及在使用这些直观手段时应遵循的原则,为学生课程目标的完成、拓展学生的思维做好有力的脚手架。
Due to the physiological defects of the blind students in the lower grades, it is necessary to use visual means to make up for the visual defects of the blind students and help the blind students to improve their abilities to abstract thinking during the teaching process. This paper discusses the application of mathematical intuition, teaching aids intuition and language intuition in mathematics classrooms of lower grades, as well as the principles to be followed when using these visual aids. It is a powerful scaffolding for the completion of students ’curricular goals and the development of students’ thinking.
