This study examined the effects of social influences in the lives of an ethnically diverse sample of fifth through eighth grade students with and without learning disabilities (LD) using survey data and academic achievement scores collected in 19 Chicago public schools from 1993–1997. Similarities and differences in student perceptions of school, family, and peer group contexts were examined. In addition, longitudinal data were analyzed using hierarchical linear modeling (HLM) to identify contextual influences on changes in student reading achievement over time. Comparisons of student responses confirm and extend existing findings in the literature concerning the perceptions of students with LD of their social environments. In particular, having a learning disability was associated with consistent, mostly negative, effects on social relations across the contexts of students’ lives, regardless of gender, race, grade, and socioeconomic status. In addition, student perceptions of their friendship groups were found to have small, but significant, effects on their growth in reading achievement over the course of middle school. While students with and without LD had somewhat different views of their social contexts, the processes working within these environments appeared to affect their reading achievement in similar ways. The results suggest that careful attention should be paid to the social contexts of students’ lives when planning academic interventions.  相似文献

The SKI*HI Institute developed a system of coactive signing to help alleviate communication and instructional barriers for children who are dual-sensory impaired (deaf and blind). The system also can be used to help children who are severely multihandicapped learn how to communicate. The system includes optimized coactive signs that are functional, easy to feel, easy to relate to the referent, and easy to make, and it also includes techniques related to effective coactive sign use. The coactive sign system is illustrated on a series of video tapes that has been field tested and produced and is being disseminated throughout the United States and Canada.  相似文献

The development of declarative knowledge was examined within the parameters of movement-based curricula. Declarative knowledge represents factual or foundational knowledge frequently articulated as curriculum content. A semantic ordered tree technique was used to investigate the knowledge structures of three groups of teacher preparation subjects (novice, coursework, student teacher) and one group of elementary physical education teachers (experts). Structures were examined based on frequency and coherence criteria. ANOVA was used to examine differences between groups. Results suggested that declarative knowledge appeared to develop in complexity from novice to expert within the parameters of concept-based movement curricula. The Active Structural Networks Theory was used to interpret structural development through the accretion, tuning, and restructuring phases. Knowledge structures of the novice and coursework groups seemed to represent accretion, whereas those of student teachers and experts represented tuning and restructuring.  相似文献

A recent report of the Committee for Economic Development observed that 30% of our children are educationally disadvantaged and face major risks of educational failure and lifelong dependency (CED, 1987). One reason advanced for this observation is that schools have neglected to prepare these children to become active citizens who can contribute to the social and economic uplifting of their neighborhoods.L.
