Sixty-one children, originally identified at the beginning of kindergarten on the basis of 4 distinct clusters of observable classroom behavior, were evaluated at completion of first grade. Teacher ratings and individual achievement test scores partially confirmed the predictive validity of the original clusters. Children in the nonrisk cluster continued to do well, while children in the high-risk cluster were still doing poorly in some areas. An unexpected finding was that children in another cluster, originally seen as nonrisk, also seemed to be in some difficulty. Concerns about specific aspects of observable behavior were discussed.  相似文献

In order to determine the point at which successive days of classroom observation results in a reliable sample of behavior, a classroom of 30 kindergarten children was observed over a period of 18 days in four behavior categories. High correlations between running and total averages were obtained around the fourth day, including low base rate behaviors. Implications for subsequent classroom observation studies were discussed.  相似文献

WISC and WISC-R test results were correlated with achievement test scores and school grades of 36 children who had completed two years of school. Global intelligence estimates from both scales correlated at significant levels with all achievement test measures. Individual subtests from the two scales were unevenly correlated with grades in specific school subjects over both school years. Data suggest that while the two scales may be grossly equivalent as global predictors of school achievement, the individual subtests from the two scales may not correlate equivalently with specific external criteria such as school grades.  相似文献

To determine whether children's observable kindergarten behavior might predict eventual educational risk, 40 of 94 children originally observed in their classrooms at the beginning of kindergarten were followed at completion of second grade. The 40 subjects appeared to be representative in that they did not differ significantly from the total sample in terms of original kindergarten classroom behavior, sex, or race. Using four clusters of kindergarten behavior, significant differences were found in eventual special placement and in ratings of teacher anecdotal material. Attending behavior correlated highly with eventual risk, leading to speculation about early identification procedures.  相似文献

So as to compare predicted achievement based upon WISC-R IQs and observed achievement by the WRAT standard scores, both instruments were administered by the same school psychologist to 282 urban students referred for psychological evaluation. The correlations obtained, even on this nonrandom population, were substantial, significant (p < .001), and should be useful to school psychologists in statistically relating intelligence test scores to school achievement.  相似文献

Behavior modification procedures are described for establishing compliant behavior in elective mutes. The results are discussed for three children to whom the procedure was applied. The length of the training period was two weeks for the first child, twelve days for the second, and six weeks for the third. Two of the three subjects generalized responsive and spontaneous language from the experimental to everyday settings.  相似文献
