While conducting this ethnography on 50 male African-American gang members, I sought to create a picture of the culture in which these young men existed. Over a two-year period, I observed and interviewed members from such groups as the Bloods, the Crips, and the Blackstone Rangers in order to uncover the values, language, and rituals that defined membership in a gang, as well as the reasons why these males joined these groups in the first place. For the majority of these males, an education was not something that they thought would help them survive in their neighborhoods. One unexpected element that emerged during this project centered on the factors that helped 11 of these gang members begin the process of escaping gang life. What they received from their families, teachers, and peers to help them succeed mirrored the same factors that were often missing in the lives of the other 39 informants.  相似文献

This article summarizes the conclusions that the authors have drawn about the measurement quality and potential for linkage with teacher pay of three sets of teacher assessments—those developed or being developed by the Interstate New Teacher Assessment and Support Consortium, the Educational Testing Service, and the National Board for Professional Teaching Standards. To investigate the feasibility of using these assessments as a framework for a knowledge- and skill-based pay system, the Consortium for Policy Research in Education commissioned a set of papers for a conference in September 1997 on the measurement issues involved in assessing teaching practice to standards and linking these assessments to pay for knowledge and skills. The resulting papers, revised and published as articles in this journal, show that this approach is promising but that in some cases additional research on the measurement quality of the assessments is needed.  相似文献

This paper reports an intensive study of problem-solving activity of female students at the senior secondary level. The study focussed both on the mathematical processing and the underlying cognitive and metacognitive activities that led to that processing. Response maps were used to analyse and categorize the written responses from individual students while videotaped problem solving sessions and structured and free response interviews probed the students' metacognitive knowledge, strategies, decision making, beliefs and affects. Metacognitive activities were involved in all phases of the solution process with key points in students' solutions identifiable in terms of the cognitive-metacognitive framework of Garofalo and Lester (1985). On average more time was spent on orientation and execution activities with little time being spent on organisation and verification activities, however, the successful groups spent less time on orientation than the other groups. All successful groups displayed a high number of key points where metacognitive decisions could influence cognitive action. Success was accompanied by a tendency to engage in a high number of organisational activities, regulation of execution activities and evaluation activities particularly evaluation of execution but fewer opportunities where metacognitive decisions could influence cognitive actions during orientation.  相似文献

This article outlines the context in which General National Vocational Qualifications (GNVQs) have been developed with particular reference to the independent learning dimension of their principles and practice. It provides an overview of the problems associated with the GNVQ approach from the literature and from a study by the authors of twelve post-16 institutions in the process of implementing Advanced GNVQ programmes. It analyses the dimensions of independent learning and argues that GNVQs provide a hybrid learner experience in which autonomy in the organisation of the individual learning process is mediated by a heavily prescribed GNVQ framework. The article concludes by locating this paradox in four central dilemmas characterising post-16 curricular policy in the UK.  相似文献

Despite current moves in the UK to limit class sizes for young children in school, there is still a disturbing lack of research evidence on the effect of class size differences on pupils' educational progress and experience. Past research has concentrated on the effects on outcomes such as pupils' school attainments in basic areas. Much less is known about classroom processes that might mediate any such effects, though such knowledge is more useful for practice and policy. Drawing on a current programme of research at the Institute of Education, University of London, this paper identifies five processes likely to be connected to class size: within class grouping practices, the nature and quality of teaching, pupil attention in class, pupil adjustment to school and effects on teachers' morale, stress and enthusiasm. Relevent research is reviewed, and in line with this research the paper concentrates on the primary school years.  相似文献

This paper argues that the theory and practice of induction and socialization of new academic staff in universities have been based on a partial, corporatist, perspective influenced by now defunct structural-functionalist theory. We develop a more sophisticated theoretical understanding of organizational socialization and explore its consequences for the practice of induction of new academic staff. These ideas are based on secondary data derived from a number of studies of new academic appointees (NAAs), 27 in-depth interviews we conducted with academics in ten Canadian and English universities, both chartered and unchartered, and a five year ethnographic study of academic staff in a single unchartered English university.  相似文献

Understanding science involves the mastery of complex networks of concepts. To design effective computer based systems for learning science it is essential to adequately characterize the nature of those conceptual networks, so that clear and appropriate instructional goals can be defined and fed into the design process. This paper considers a novel class of representations for science instruction — Law Encoding Diagrams (LEDs) — and describes the nature of scientific understanding based on these representations. A framework of four classes of schemas has been proposed to characterizes problem solving and learning with LEDs. How the framework encompasses complex networks of concepts is discussed and the implications for the design of computer based learning environments based on LEDs are considered.  相似文献
