Microcounseling techniques were used to conduct an experimental study. The objective was to train naive college students who were interested in counseling to assess clients' attitudes toward guidance tests. A correlation of .797 was obtained between clients' ratings of attitudes toward tests and the trainees' ratings of clients' attitudes toward tests. Findings were consistent with the results of other microcounseling studies. Individual differences among the trainees were noted and comparisons were made between the trainees' own ratings, judges' ratings, and clients' ratings of trainees. Lack of a control group imposes a serious limitation on interpretation of the results. 相似文献

This article reports on an ethnographic study of a 10-year-old's pursuit of school-based mathematics across school and home to suggest that participating in school-based mathematics is a cross-setting phenomenon in at least 2 ways. First, I illustrate how accomplishing school-based mathematics literally extends into the home and how individuals recruit resources from their histories of participation in alternative settings to accomplish the work of school-based mathematics. Second, I show how a youth's social identification in the classroom is shaped by his teacher's partial accounts of how learning is arranged for in the home. Approaching participation in school-based mathematics as a cross-setting phenomenon illustrates the complexity inherent in participating in schooling and raises questions about how to coordinate schooling across school and home settings. 相似文献

This study investigated reciprocal relations between adolescents' physical aggression and their perceptions of peers' deviant behaviors and attitudes. Analyses were conducted on four waves of data from 2,290 adolescents (ages 10–16) from three urban middle schools. Autoregression models revealed reciprocal relations between peer factors (i.e., friends' problem behavior, peer pressure for fighting, friends' support for fighting) and adolescents' reporting of their aggressive behavior. Bidirectional relations were also found between peer pressure for fighting and adolescents' frequency of physical aggression based on teacher ratings. Findings were consistent across sex, grade, and time. Findings suggest that multiple dimensions of peers' behaviors uniquely play a role in the development of adolescents' aggression and have important implications for interventions to reduce problem behaviors. 相似文献

In the previous article, we studied notions such as algorithmic universality, computability, and incomputability. In this article, we study the notion of correctness of programs, illustrate a method of establishing the correctness of programs and discuss issues in the development of correct software. 相似文献

High- and low-IQ children in the first, third, and fifth grades performed two free-recall tasks: a sort-recall task with sets of categorically related pictures, and a class-recall task, with children recalling the current members of their school class. All children were deemed to be experts concerning the composition of their school class, but, unlike experts in other domains, had no special motivation associated with their expertise. Recall and clustering on both tasks were high. The high-IQ children performed better than low-IQ children only on the sort-recall task. IQ was significantly correlated with measures of performance on the sort-recall task but not on the class-recall task. The results reflect the fact that the memory benefits associated with being an expert (here, elimination of IQ effects) are related to the greater knowledge the expert possesses and not to factors of motivation. 相似文献

The purpose of this article is to explore the intersectionality of autism and sociocultural factors as well as discuss the complexities associated with appropriate assessment, diagnosis, and intervention. Based on a review of the literature, the authors present a brief history of the emergence of the term autism and highlight factors that have contributed to current concerns about failures to appropriately recognize autism within diverse populations. Referencing extant research as well as professional practice standards, this article examines aspects of autism and intersectionality, and explores some of the associated challenges related to assessment, diagnosis, and intervention. Further, the authors reflect on the critical importance of carefully considering all aspects of a child's identity when engaging in autism assessment and intervention within the school setting. School-based practitioners are provided with guidance for addressing the needs of diverse populations of students with autism. 相似文献

This study examined the relative influence on children's self-esteem of academic achievement, maternal self-esteem, maternal acceptance, and children's perception of their parents' acceptance of them. Subjects were students with learning disabilities in a self-contained class (n=31), similarly diagnosed students in resource room (n=35), students in compensatory education (n=30), and nondisabled students (n=30) from Grades 3 through 6. Results showed that for the self-contained group, a child's perception of maternal and paternal acceptance plus the child's academic achievement score accounted for 58% of the variance in the child's self-esteem. None of the independent variables accounted for a significant proportion of the variance in the compensatory education and regular class groups. The self-esteem of the regular class students was significantly higher than that of the resource room students and the compensatory education students, but not significantly higher than that of the self-contained students. 相似文献
