聋生由于听不到声音,缺乏听觉信息的输入,从而制约了思维的发展,最终导致综合能力发展缓慢。因此在数学学习中对应用题、几何图形的认识和概念的理解等具有一定的难度。为解决这一难题,可采用多媒体技术辅助教学,强化视觉信息,以弥补听觉信息缺失的不足,激发学生的学习兴趣,提高教学效率。 Deaf students, because they can not hear the sound, lack the input of auditory information, thus restricting the development of thinking and eventually leading to the slow development of comprehensive ability. Therefore, in mathematics learning problems, geometry and understanding of the concept of understanding has a certain degree of difficulty. To solve this problem, multi-media technology can be used to assist teaching and strengthen visual information to make up for the lack of auditory information, stimulate students’ interest in learning and improve teaching efficiency.
