This study sought to examine distinctions in social competencies between children with learning disabilities (LD) and other children who also experience academic difficulties. Eighty-five children with LD (54 male, 31 female) in Grades 3 through 6 from a large urban school district were compared to a group of low achieving (LA) peers matched on achievement as well as sex, race, and grade. The samples were 42% black, 39% Hispanic, and 19% Anglo. Both groups completed two self-concept questionnaires, a loneliness scale, and a measure of their social relationships outside of school. In addition, their classmates completed a peer rating scale and their teachers completed two ratings of the child's social skills. The results indicated that children with LD and LA children were comparable on most measures, although children with LD reported themselves as being less lonely than LA children. In addition, regular-class children rated children with LD as more likable than LA children. The results highlight similarities in the social competencies of children with LD and LA children and suggest that special education classes may offer some social advantages to children with mild handicaps.  相似文献

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker, Goldstein, & Heffernan, 2010 Baker, R. S. J. d., Goldstein, A. B. and Heffernan, N. T. 2010. “Detecting the moment of learning”. In Proceedings of the 10th Annual Conference on Intelligent Tutoring Systems 2534. In V. Aleven, J. Kay, & J. Mostow (Eds.),pp.Heidelberg, Germany: Springer.[Crossref] [Google Scholar], 2011). Two coders labeled data from students who used an intelligent tutoring system for college genetics. They coded in terms of 7 forms that the moment-by-moment learning curve can take. These labels are correlated to test data on the robustness of students’ learning. We find that different visual forms are correlated with very different learning outcomes. This work suggests that analysis of moment-by-moment learning curves may be able to shed light on the implications of students’ different patterns of learning over time.  相似文献

Highlighting the unique educational needs of gifted and high ability preschoolers, this article guides the reader to consider the characteristics of young gifted children along with appropriate assessment practices in planning educational programming. A triarchic approach to programs and services for gifted preschoolers is outlined with major emphases on an integrated curriculum, ongoing evaluation, and parental involvement. Specific strategies including internet resources are described to guide practitioners in providing optimal learning environments for this distinctive student population.  相似文献

The understanding and use of historical concepts specified in national history standards pose many challenges to students. These challenges include both the acquisition of content knowledge and the use of that knowledge in ways that require higher order thinking. All students, including adolescents with learning disabilities (LD), are expected to understand and use concepts of history to pass high-stakes assessments and to participate meaningfully in a democratic society. This article describes Content Enhancement Routines (CERs) to illustrate instructional planning, teaching, and assessing for higher order thinking with examples from an American history unit. Research on the individual components of Content Enhancement Routines will be illustrated with data from 1 of the routines. The potential use of integrated sets of materials and procedures across grade levels and content areas will be discussed.  相似文献

There is much disagreement in the literature over the extent to which graduates are mismatched in the labour market and the reasons for this. In this paper we utilise the Flexible Professional in the Knowledge Society (REFLEX) data set to cast light on these issues, based on data for UK graduates. We find substantial pay penalties for overeducation for both sexes and for overskilling in the case of men only. When both education and skill mismatch variables are included together in the model only overskilling reduces job satisfaction consistently for both sexes. Using job attributes data it appears that the lower wages of the overqualified may in part simply represent a compensating wage differential for positive job attributes, while for men at least there are real costs to being overskilled.  相似文献

This longitudinal study evaluated the extent to which maternal responsiveness across early childhood and children's cognitive skills predicted children's 8-year decoding and reading comprehension skills for children who varied in biological risk (term, n = 83; preterm, n = 155). Patterns of maternal responsiveness during infancy (6, 12, and 24 months) and preschool (3 and 4 years) revealed 4 maternal clusters that varied in consistency and level of maternal responsiveness. Although not predictive of decoding skills, the interaction between children's 4-year cognitive ability and maternal responsiveness cluster predicted children's reading comprehension skills at 8 years of age, regardless of risk. Although consistently high levels of maternal responsive parenting across early childhood related to literacy outcomes for all children in the study, responsive parenting had a stronger relation to later reading comprehension skills for children with lower cognitive abilities, particularly when mothers demonstrated high responsiveness in children's infancy.  相似文献
