As a part of efforts to evaluate and monitor the increasing public investment in early childhood education, teachers are being asked to assess children's school readiness. In this study, preschool teachers and kindergarten teachers rated children's skills in three areas (kindergarten readiness, academic skills, and communication skills), and these ratings were compared with direct assessments of the children's skills. Ratings by both groups of teachers tended to be more highly related to basic skills, such as counting and number naming, than to abilities such as solving applied problems and using expressive and receptive vocabulary. Preschool teachers' ratings had a lower association with children's observed skills and abilities than kindergarten teachers' ratings. Ratings of children attending Head Start were systematically inflated, but this relationship was mediated to a significant extent by the teachers' levels of education. More educated teachers rated children in a manner consistent with the children's directly assessed skills. Implications of these findings for informing future efforts to assess school readiness by using teacher ratings are discussed.  相似文献

Evidence shows that initial and advanced learning to read are predominantly mediated by the right and left cerebral hemispheres, respectively. Premature reliance on left-hemispheric reading strategies may result in L-type dyslexia, characterized by hurried and inaccurate reading. P-type dyslexia, characterized by a slow and fragmented style of reading, may result from the inability to shift from the predominant generation of right-hemispheric reading strategies to the predominant generation of left-hemispheric reading strategies. Results of investigations concerning the validity of the L/P-typology are discussed, as are the reading effects of hemisphere-specific and hemisphere-alluding stimulation in children with L- and P-type dyslexia.  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

Naoko Saito has made a good case for emphasising the 'tragic' dimension within Dewey's pragmatism. My response suggests ways in which Saito has not gone far enough. She does not adequately move beyond 'procedural pragmatism' to a 'programmatic pragmatism' which offers substantive articulations about the human good. In addition, her emphasis on 'Emersonian perfectionism' is misguided. Both the language of 'perfectionism' and the figure of Emerson are unsuitable for the project she intends. Speaking more concretely of a 'tragic–comic meliorism' allied to the novelist Hawthorne, it is suggested, provides a more fruitful path.  相似文献

Collaboration in research activity is now the rule not the exception. It is encouraged by government, funding bodies and research councils. However, the concept of collaboration is difficult to define. It occurs at many different levels, driven by a complex research system-policy dynamic. Three different models of collaboration – inter-personal, team and corporate – are identified, each with their own rationale, structure, benefits and costs. The paper examines the institutional implications of these models. It argues that institutions and individual researchers conceptualise and operationalise research collaboration in different ways. Although vital to institutional mission, collaborative research is rarely mapped by senior managers with any precision. In general, institutional approaches to the management of collaborative research lag behind the policy rhetoric. The paper concludes with an overview of the key dilemmas for institutional strategists and policy makers posed by the shift towards more collaborative approaches to research.  相似文献
