The United Kingdom faces a decline in the 18-year-old cohort from 900,000 + in the mid-1980s to 600,000 + in the mid-1990s. Will a third of the universities close? More important, will industry and commerce cope with the potential reduction in skilled manpower production? A method is described for forecasting graduate numbers and their quality by discipline, and suggestions are made about ways in which society could react so as to influence unacceptable trends.  相似文献

Although structuration theory (ST) has endured a considerable influence in communication research across various domains, there remains a paucity of quantitative empirical research using ST as a viable framework. The purpose of this article is to develop an adapted structurational framework to explain the emergence of communication networks. The adapted framework distinguishes between relational states/events and internal/external structural rules. For analysis, we introduce multipanel relational event modeling, a technique using processual inference that can empirically demonstrate the recursive nature of system and structure. As an introductory example of both the framework and method, we examined communication, using cell-phone data, of students living in the same dormitory from September 2008 through February 2009. Our results demonstrated how different structures (i.e., perceived social relations and internal/external structural rules) are reproduced and transformed over time. Our research has implications for communication research dealing with recursivity, event-driven network analysis, the changing nature of the phone call, and the promise of computational communication science.  相似文献

This study assessed the reported responses of junior high school students with learning disabilities and normally achieving classmates to peer pressure to conform in prosocial and antisocial activities. The results replicate those of an earlier study in finding that students with learning disabilities indicated more willingness than their classmates to conform to peer pressure to engage in antisocial actions.  相似文献

Our paper builds on the construct of the zone of proximal development (ZPD) (Vygotsky in Mind in society: the development of higher psychological processes, Harvard University Press, Cambridge, 1978) to analyze the relationship between students’ answers and the help they receive as they construct them. We report on a secondary analysis of classroom and interview data that was collected with 1st and 2nd grade students completing a short scaffolded inquiry project designed to help them learn about how honeybees collect nectar. We explore how the progression of questions reveal students’ understanding of complex systems by examining how students’ progression through the questions tended to become more sophisticated as we increased support. We further compare two complex-systems perspectives, Component-Mechanism-Phenomena and agent-based approaches, to see how each would categorize students’ explanations. Findings demonstrate the value of the ZPD as an analytic framework in exploring students’ systems understanding in terms of the nature of questions (e.g., sequencing, type of question) and multiple conceptual models (e.g., component-mechanisms-phenomenon, single agent or aggregate behaviors), and how this might impact students’ groupings according to their ability and subsequent instructional support.  相似文献

Using cognitive ethnography as a guiding framework, we investigated US and Japanese fourth-grade teachers' domain knowledge of key fraction representations in individual interviews. The framework focused on revealing cultural trends in participants' organization of knowledge and their interpretations of that organization. Our analyses of the interviews, which included a representation sorting task, indicated three major differences that defined US and Japanese teachers' approaches to rational number representation: (1) Japanese teachers interpreted all rational number representations as conveying primarily mathematical information, whereas US teachers interpreted only some representations as conveying primarily mathematical information; (2) the US teachers focused more intently on part-whole relations than Japanese in their interpretations; and (3) Japanese teachers more easily linked rational number representations to more advanced upcoming content in the curriculum. A review of US textbooks used by the teachers reflected their consistency with US teachers' interpretations of the representations. These findings imply that strong cultural differences underlay the approaches that teachers in both nations take to rational number representation and that these differences may help explain established cross-national differences in student reasoning.  相似文献

This article examines the literature on Native science in order to address the presumed binaries between formal and informal science learning and between Western and Native science. We situate this discussion within a larger discussion of culturally responsive schooling for Indigenous youth and the importance of Indigenous epistemologies and contextualized knowledges within Indigenous communities.

In the wake of recent school shootings, fear over violence in schools has prompted increased requests for psychologists, educators, and law enforcement professionals to assist in preventing future school violence incidents. We attempt to lay a foundation for developing effective assessment and prevention approaches by first distinguishing planned school‐based attacks from other forms of school and youth violence. We then review the three assessment approaches that have been advocated and used in some jurisdictions (profiling, guided professional judgment, automated decision‐making) and demonstrate why they are inappropriate—and potentially harmful—in preventing planned school‐based attacks. We then describe the contours of the threat assessment approach, developed by the U.S. Secret Service to prevent assassinations, and examine its utility for responding to communications or behaviors of concern that students may present in school settings. © 2001 John Wiley & Sons, Inc.  相似文献

This study argues that maximizing early childhood educators' abilities to create social opportunities for co-construction of knowledge rests on two understudied assumptions, one theoretical and one empirical. Theoretically this study rejects the notion of language as an impartial conveyor of knowledge in favor of one in which math and language interact. This alternative framework is termed Math- Mediated Language (MML) and argues that the perception of common terms that adults possess is an important part of the knowledge that practitioners possess about linking conceptually related linguistic and mathematical knowledge. Empirical findings from a survey recording participants' reactions to seven categories of terms with mathematical meanings and three categories of distracter terms were analyzed. The data indicated that when asked to think about math, practitioners more readily accessed words for operation terms than relational terms. Additionally, participants demonstrated stronger tendencies toward additive terms conveying addition or subtraction concepts over multiplicative ones conveying multiplication or division concepts. The findings point to patterns in the ways that participants view mathematical language demonstrating that language interacts with even simple interpretations of basic mathematical terminology. The implications of this are that practitioners interpretations of everyday language may influence their ability to see opportunities for teaching mathematical concepts not only in the context of an explicit math lesson but throughout the broader early childhood curriculum.  相似文献
