Psychological Factors Related to Early Reading Behavior of Educable Mentally Retarded and Normal Children. Interim Report by Leonard S Blackman( Book )

3 editions published in 1970 in English and held by 4 WorldCat member libraries worldwide

Efforts to establish what psychological processes make up the framework through which beginning reading skills are developed led to this study, aimed at identifying perceptual, learning, cognitive, memory, and language variables which influence beginning reading of normal and educable mentally retarded children. A total of 172 first-grade subjects, 78 in the normal group and 94 in the retarded group, were chosen on the basis of Peabody Picture Vocabulary Test (ppvt) scores. These children, from 11 New York City schools, were also tested using the Metropolitan Achievement Tests (mat), the Wide Range Achievement Tests (wrat), and 17 readiness measures, all composed of verbal material. Factor analysis and other multiple regression procedures were used to analyze the data. Significant differences, attributable to the differences in mental age, were found between the two groups on almost all measures. Among the findings were that (1) auditory and visual skills were dominant for the retarded group, (2) only auditory skills were pertinent for the normal group, (3) a visual wordness subtest was the best predictor for the retarded group, and (4) a learning sample subtest correlated with skill acquisition for both groups. Tables and a 130-item bibliography are included. (Ms)

The Development and Evaluation of a Curriculum for Educable Mental Retardates Utilizing Self-Instructor Devices or Teaching Machines by Leonard S Blackman( Book )

1 edition published in 1964 in English and held by 2 WorldCat member libraries worldwide

An evaluation of self-instructional devices in the classroom and the related psychological research were presented. Part 1 covered phases of machine and program development, a review of relevant literature, and the major experiment. Educable mentally retarded 14-year-olds were selected and divided into two groups. The experimental group consisted of 19 persons and the control group, 17 persons. Both groups were pre- and post-tested at the beginning and end of the year. The experimental group received programed instruction and the control group was taught conventionally. An analysis of the data collected showed negative results in the effectiveness of machine instruction skill development with the exception of one arithmetic measure. Further research was encouraged to study the psychological properties of school tasks. Part 2 included theoretical statements and literature surveys. (Rs)
