Passage2 Videodisc holds great promise of helping tomeet the needs of American schoolchildren who have problems seeing, hearing,speaking, or socializing. Almost eleven percent of the students aged 3~21 inthis country have an impairment that affects their ability to benefit from aregular education program. Handicapped students require special education becausethey are often markedly different from most children in one or more of thefollowing ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped,physically handicapped, or other health impairments. The education of thesehandicapped children is rewarding but challenging. A special education student usually needs alonger period of time to acquire information. Repetitive teaching techniquesare often beneficial, and indefatigable (孜孜不倦的) consistency on the part of the teacher is frequently necessary.Interactive videodisc course ware has characteristics that can be capitalizedupon to meet the challenges that special education poses. A videodisc programis infinitely patient. Repetition of any videodisc lesson can continueendlessly, and designers can assure absolute consistency within a program.

He believes that forspecial education, the power of videodisc lies in the ability of the technologyto visually represent language concepts normally taken for granted bynon-handicapped persons. Complex figurative language forms such as idioms andmetaphors come most readily to mind as being difficult for handicappedlearners. 61.
