37 mainstreamed educable mentally retarded (EMR) children in Grades 3, 4, and 5 were randomly assigned to a control group or to an experimental treatment given during regular class activities for the purpose of improving their social status among nonretarded classmates. On the average, Ss were 8–20 mo older than their normal classmates. Each experimental S worked in a small cooperative group with 4–6 nonretarded classmates on highly structured, manipulative tasks using multimedia materials. The treatment was provided in 2 cycles which lasted a total of 8 wks. Sociometric tests were given before and after treatment to pupils in classes with experimental and control EMR Ss. By 2–4 wks following completion of treatment, nonretarded Ss' social acceptance of their experimental peers improved significantly more than that of control Ss. (17 ref)
Item responses of Spanish-and English-speaking children on Raven's Coloured Progressive Matrices were submitted to principal components analyses and varimax rotations. Four factors were obtained which corresponded to readily identifiable problem types. The finding that three of the four factors were comparable for the two groups of subjects indicated the factorial invariance of the Raven test with children from different cultural backgrounds.EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT 1974, 34, 977-981.
Item responses of two samples of normal and educable mentally retarded (EMR) children on Raven's Coloured Progressive Matrices were submitted to a principal components analysis and varimax rotation. Four factors were obtained which corresponded to readily identifiable problem types. The factor structure for both retarded and nonretarded subjects was replicated by an independent sample. Comparability of factor structures of normal and retarded subjects indicated the factorial invariance of this test with children of different IQ levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
