分数是学生对数的认识的一次飞跃,是学生学习的一个难点,更何况是有视觉障碍的盲生。分数的学习能增强盲生的数感,提高其日常生活和将来就业后的工作实践能力,为后续学习打下基础。通过对分数的概念、分数的四则运算以及有关分数知识的应用,重点、难点的理解,教学举例分析研究,供盲校数学老师借鉴参考。 Score is a leap in the understanding of student logarithm, is a difficult point for students to learn, let alone blind students with visual impairment. Fractional learning can enhance the sense of number of blind students, improve their daily life and future employment after the practice ability, lay the foundation for follow-up study. Through the concept of scores, the scores of the four operations and the application of knowledge about points, emphasis, difficult to understand the teaching of example analysis for the blind school mathematics teacher for reference.
