Duchenne Muscular Dystrophy (DMD) is a neurogenetic developmental disorder that presents with progressive muscular weakness. It is caused by a mutation in a gene that results in the absence of specific products that normally localize to muscle cells and the central nervous system (CNS). The majority of affected individuals have IQs within the normal range, generally with lower verbal than performance IQ scores. Prior work has demonstrated selective deficits on tests of verbal span and immediate memory. For the current study, 26 boys with DMD (and normal intellectual function) and their unaffected siblings were evaluated. Paired comparisons demonstrated that the children with DMD had significantly poorer academic achievement scores than their siblings, even though their vocabulary levels and home and educational environments were comparable. Children with DMD also had more behavioral concerns, physical disabilities, and poorer verbal memory spans. Linear regression indicated that behavioral concerns, executive function, and physical disability did not contribute substantially to academic performance, whereas performance on verbal span did. DMD presents with a selective developmental aberration in verbal span that has wide‐ranging consequences on learning skills.  相似文献

This paper explores some of the problems arising when Continuous Assessment (CA) is grafted onto established pedagogic practices. It focuses on three issues: teachers' restricted understandings of assessment, teachers' emphasis on criteria that demonstrate concern with social control, and some of the problems connected with peer assessment. Two vignettes derived from fieldwork associated with a project to improve the quality of primary education are used to raise the issues. We argue that the development of desired practices is hampered above all by tacit values in tension with those underpinning the new curriculum. These values, together with the complexity of curriculum design, create serious problems of manageability and interpretation, which can only be addressed through detailed interactive in-service training, aimed at reconceptualising teachers' notions of assessment.  相似文献

In recent years university presses have undergone some significant changes, such as expansion of their scope to include materials that may have appeal beyond the scholarly market. This article investigates, through the use of a survey of university libraries, the acquisition of university press products by libraries. In general, recent years have been changes in the relationship between university presses and libraries that have resulted in fewer items being purchased by the libraries.  相似文献

Three factors tied with secondary student success in content‐area reading are demonstrated: (a) validated teacher‐focused and student‐focused interventions, (b) integrated and comprehensive service delivery systems, and (c) well‐designed, data‐based professional developmental programs. Difficult challenges face secondary students with LD and their teachers with regard to these students’ participation and success in required general education classes. Recently, instructional methods and materials have been developed and validated for promoting these students’ success. Some of them focus on how general education teachers plan and teach their content‐area courses; others focus on giving students the strategies they need to respond independently to the demands of their courses. This article describes these instructional methods, a service‐delivery model for implementing these interventions in secondary schools, and professional‐development mechanisms and administrative support that must be in place for the model to be maintained effectively.  相似文献
