心理学研究表明,人们主要通过各种感觉器官接受外来信息和接受知识,按其比例:视觉占83%,听觉占11%,嗅觉、触觉、味觉共占6%。从外界经5个感官接受到的信息传入大脑后,存储及运用这些信息需要内视觉(对应视觉)、内听觉(对应听觉)、内感觉(对应嗅觉、触觉、味觉等)的参与。培智学校的学生,由于先天不足,无法像正常孩子一样去感受生活,他们更需要借助多种感官来调动学习的热情。培智学校的课堂必须以智障学生的实际需要为 Psychological studies show that people receive foreign information and accept knowledge mainly through various sensory organs. According to their proportion, 83% of vision, 11% of auditory sense and 6% of sense of smell, touch and taste together. After the information received from the outside through the five senses is transmitted to the brain, the storage and use of such information requires the participation of internal vision (corresponding to vision), internal hearing (corresponding to hearing), internal feeling (corresponding to sense of smell, touch, taste, etc.) Students at Peizhi schools, due to their inherent deficiencies, can not feel the same lives as normal children, they also need to use a variety of senses to arouse their enthusiasm for learning. The classrooms of the school should be based on the actual needs of the students with intellectual disabilities
