Visual Perception Characteristics And School-based Curriculum Development Of Children With Intellectual Disability

Visual perception is the basis of special children perceive things,the devel opment of visual perception is conducive to improve their cognitive development,social adaptation and so on.At present,most special children have abnormal visual perception,some researchers have published the scale of special children' perception,but relevant theoretical and practical studies are still insufficient.Based on this,this study takes children with intellectual disability as the research object,analyzes their visual perception characteristics,and develops corre sponding school-based curriculum.The study is divided into the following parts:Firstly,summarizes the research content related to visual perception and school-based curriculum development.It mainly sorts out and grasps the existing research achievements and research progress,and provides reference and basis for the follow-up research on the visual perception characteristics of mentally disabled children and the development of school-based curriculum.Secondly,analyzes characteristics of children with intellectual disability about their visual perception.It uses《the Special Children's Perceptive Assessmen t Scale》,selects 335 children with intellectual disability of grade1-9 and 180 ordinary children of age3-6,analyzes their visual perception.The results showed,there are significant differences in visual perception among children with int ellectual disability,between children with intellectual disability and ordinary children.Thirdly,develop the school-based curriculum based on visual perception of children with intellectual disability.This section includes setting goals(General goals,Specific goals),designing content(Brightness,Color,Shape,Linear scale,Size,Orientation),carrying out implementation and evaluating courses(Objectives,Content,Process and Effect of school-based curriculum).Fourth,discussion of study.Based on the research,it can be seen that the overall development level of visual perception of children with intellectual dis abilities is low and the dimension development is unbalanced.The developed school-based curriculum has scientific goal setting,reasonable content design,co mplete implementation process,diverse implementation forms and good implementation effect.Fifth,summary of study.It includes summary,innovation,outlook and defect.Among them,the prospect and deficiency are mainly expounded from the following three aspects: enriching samples,improving scales and increasing cases.
