Institutional administrators, faculty, state planners, and legislatures have little analytical basis available to help them cope with the expected excess higher education capacity of the 1980s. Without objective criteria, state planners and legislatures are likely to propose across-the-board reductions even if it were preferable to close some institutions and expand others. This study is a case application of an optimization model to two community colleges in northern Minnesota. Using estimated enrollment demand functions and readily available data on size, quality, and costs, this model is designed to assist policymakers in identifying overbuilt institutions and programs that should be closed. The state's objective in the model is to satisfy specified proportions of enrollment demand with a minimum expenditure of state funds.  相似文献

Cognitive load theory (CLT) has been successful in identifying instructional formats that are more effective and efficient than conventional problem solving in the initial, novice phase of skill acquisition. However, recent findings regarding the “expertise reversal effect” have begun to stimulate cognitive load theorists to broaden their horizon to the question of how instructional design should be altered as a learner's knowledge increases. To answer this question, it is important to understand how expertise is acquired and what fosters its development. Expert performance research, and, in particular, the theoretical framework of deliberate practice have given us a better understanding of the principles and activities that are essential in order to excel in a domain. This article explores how these activities and principles can be used to design instructional formats based on CLT for higher levels of skills mastery. The value of these formats for e-learning environments in which learning tasks can be adaptively selected on the basis of online assessments of the learner's level of expertise is discussed. In their preparation of this article, the first and last authors were supported by an Internationalization grant from the Netherlands Organization for Scientific Research (NWO, The Hague, project number 411-01-010).  相似文献

This article describes the application of Bakhtin's (1981, 1986a,b) theorisation of language as dialogue to the study of young students' struggle with discourses of ethnicity within the context of a Studies of Asia curriculum project (Hamston 2003). Bakhtin's rich conceptualisation of the productive and ethical nature of dialogue has operated at all levels in this study as a theoretical, pedagogical, methodological and analytic research construct.  相似文献

This study examined the effects of rewards on the ideational fluency of 75 preschool children. Assigned to a reward or nonreward condition, the children were administered two ideational fluency tasks, Unusual Uses and Pattern Meanings. Analyses revealed a significant main effect for reward on the ideational fluency components of originality, total fluency, and flexibility. In all cases the rewarded subjects scored lower than the nonrewarded group. These findings support the growing body of evidence that rewards are detrimental to creative functioning.  相似文献

Evidence of substantial growth in unionization among university noninstructional staff over the past 20 years (Hurd and Woodhead, 1987) and the emergence of a quality movement in higher education linking employee attitudes toward the work environment with increased productivity point to the need for additional research into union and nonunion staff perceptions of the work environment. This paper describes a conceptually oriented, exploratory study of the university work environment as perceived and defined by union and nonunion noninstructional staff.  相似文献

Abstract

Psychologists and mathematics educators have long viewed flexibility as critical to students’ mathematical development. In this paper, we focused on the multidimensional nature of flexibility to better understand how preference, knowledge, and use of effective methods for solving algebra problems are related. In Study 1, we identified research-based aspects of flexibility with algebra and assessed students on them following a two-step equations unit. Results indicated that certain aspects of flexibility develop prior to others and that prior knowledge of algebra plays a significant role in that development. Study 2 confirmed and elaborated on these results using a larger sample size. Implications for theory and for supporting flexibility in classrooms are discussed.  相似文献

The role of higher education has changed in the United States. It has become a learning society where egalitarian pressures for equal opportunities led to the expansion of educational services to broader and more representative segments of society. Five propositions illustrate the current pressures for change. (1) Institutions of higher education no longer enjoy a monopoly on the provision of educational services. The learning society has given higher education new competition for the growing adult market. (2) The roles of education providers are increasingly blurred. (3) Higher education no longer has the full‐time commitment of students or of faculty. (4) Lifelong learning has become a lifelong necessity for almost everyone, which demands flexibility and responsiveness to change on the part of higher education. (5) A change is needed in the methods of teaching and learning to accommodate adult learners and to provide for the long‐ range needs of the learning society.  相似文献

Orthographic knowledge is the understanding of how spoken language is represented in print. However, the terms used to describe the two levels of orthographic knowledge, lexical and sublexical orthographic knowledge, have been variably defined and inconsistently measured, potentially contributing to discrepancies in research findings. Dissimilarities in how orthographic knowledge has been operationally defined and measured and the associated differences in tasks used to assess that construct are discussed. As part of that discussion, we relate how some measures assess either implicit or more explicit levels of orthographic knowledge. Using current theories and the existing research, we next provide an argument for how initial development of sublexical orthographic knowledge occurs before lexical orthographic knowledge. Suggestions are provided for what researchers might do in the future to help move the field toward a better understanding of orthographic knowledge. Strategies for assessing orthographic knowledge in literacy research are offered.
