In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.

The authors conducted a phenomenological study to explore the experiences of 32 school counselor educators preparing preservice school counselors. Analysis of data from 3 focus groups revealed 3 themes: breadth versus depth, balancing specialties and professor partiality, and preparation versus practice. These results highlight the need for collaboration across counseling specialties at the preservice level.  相似文献

The theoretical part of this paper argues for an embedding of the question of stability and change of teachers’ conceptions of learning into the researchers epistemological standpoint. The empirical part illustrates this statement by showing how changes in a teacher's conception of learning could be understood from a constructivist perspective. According to this perspective, conceptions are related to other relational and environmental variables that form a meaningful configuration. Thus, although conceptions of learning appear as relatively stable cognitive structures, they are also related to environmental variables to be managed by the teachers’ educators. This research result determines the discussion of the basic questions addressed in the title of this paper: why do we want to change teachers beliefs and how could we, as teachers’ educators, support these changes.  相似文献

Whether someone has ever had free school meal (FSM) eligibility over a six‐year period is the measure of socio‐economic disadvantage currently used in the English school system. It is used to monitor the socio‐economic gap in achievement in the education system, to identify particular children at risk of low achievement and to direct funding to particular children and schools. In this paper we assess how well this measure predicts pupil attainment in secondary school in comparison to other measures of socio‐economic background known to influence pupil attainment, such as parental education or income. We ask whether the FSM measure is an adequate proxy for a pupil's socio‐economic disadvantage in an educational context. To do this we draw on the Longitudinal Study of Young People in England and matched administrative data. We find that the FSM eligibility measure correlates highly with other measures of socio‐economic disadvantage, however it does not identify all children living in what would be deemed deprived households. We then compare the extent to which the FSM eligibility measure predicts educational achievement relative to other measures of deprivation and find that its predictive power is only marginally lower than many richer survey measures. This provides some reassurance on its use in policy.  相似文献

Four pigeons responded on a two-component multiple token-reinforcement schedule, in which tokens were produced according to a random-interval 30-sec schedule and exchanged according to a variable-ratio 4 schedule in both components. To assess the effects of contingent token loss, tokens were removed after every second response (i.e., fixed-ratio 2 loss) in one of the components. Response rates were selectively lower in the loss components relative to baseline (no-loss) conditions, as well as to the within-condition no-loss components. Response rates were decreased to a greater degree in the presence of tokens than in their absence. To control for the effects of changes in the density of token and food reinforcement, two parts consisted of additional conditions where food density and token loss were yoked to those in a previous loss condition. In the yoked-food condition, tokens were produced as usual in both components, but the overall density of food reinforcement in one of the components was yoked to that obtained during a previous token-loss condition. In the yoked token-loss condition, tokens were removed during one component of the multiple schedule at a rate that approximately matched the obtained rate of loss from a previous token-loss condition. Response rates in these yoked components were less affected than those in comparable loss components, despite similar densities of token, exchange, and food reinforcement. On the whole, the results support the conclusion that contingent token loss serves as an effective punisher with pigeons.  相似文献

Student diversity has increased within Australian universities. This has changed the teaching and learning needs of students. The implementation of quality was aimed at enhancing the quality of the higher educational product. However, the policy, while providing an accountability framework at the institution level, failed to provide the structural mechanisms needed to achieve quality in the teaching and learning the students receive, that is the sub‐faculty level. Other factors, such as the potential growth of non‐government resources in the form of more international students have perhaps a greater chance of improving the quality of teaching and learning within the faculties, because they provide both the funds and an incentive for more funds as a reward for implementing quality assurance within the teaching and learning function of universities.  相似文献

A major investment in educational television programmes by the federal government led the United States Department of Education to seek ways to extend the audience size for these programmes beyond public television by placing them on commercial broadcast stations in America. This article describes the programmes, the marketing organization and strategies used to promote programming to the commercial marketplace, and the successes achieved in persuading commercial broadcasters to accept educational children's programming, particularly programmes aimed at minority audiences.  相似文献

The aim of this study is to elicit from staff members and from postgraduate students their personal constructs of research effectiveness. Based on Kelly's Personal Construct Theory, the repertory grid technique was used to elicit, analyse, discuss, and negotiate individual and group constructs of research with the result of arriving at a greater group consensus and a clearer picture of shared criteria for research effectiveness.  相似文献

The present study aims at assessing faculty attitudes toward institutional competitive strategies in U.S. research universities and at exploring some of the correlates of these attitudes.

A stratified random sample of 40 U.S. research university departments, 10 each in physics, sociology, electrical engineering, and education was surveyed by means of a questionnaire.

The major findings of this study suggest that faculty members at research universities express non‐receptive attitudes toward university generic strategies, although, more productive,more satisfied and more committed faculty members are relatively more receptive toward university strategies than less productive, less satisfied and less committed faculty members.

The meaning and the implications of these findings are discussed.  相似文献
