The application of performance based criteria in the allocation of resources and the targeting of substantial research funds to topics of national priority are two major features of the new research funding climate in Australian higher education. Successful competition for such funds will depend on universities developing and implementing appropriate research management plans and on the overall research performance of their academic staff. This paper reports the views of academic staff from one Australian university on such issues as the determinants of research performance and the importance of individual autonomy in the selection of research topics. One of the main findings is that research activity is highly variable and influenced by a number of factors including, personal characteristics; differences in research styles, methods and strategies both within and between disciplines; and dependence on funding. The findings show that academics firmly believe in freedom of inquiry in the choice of research topic. 相似文献

A school system and a university joined forces to improve the science and mathematics environment for local minority students with a program that utilized computer technology. The initiative involved individual students from all of the high schools in the Winston–Salem/Forsyth County (North Carolina) School System. In this initiative, Wake Forest University operated a two-week Summer Science and Math Experience for minority students. During the two weeks, students worked intensively with computers and, at the end of the summer program, a laptop computer was loaned to each student for personal use during the of school year. Through interviews and questionnaires, students overwhelmingly endorsed their involvement in the computer-oriented project, both the summer and academic year phases. They especially liked having access to the Internet (provided by the project), being able to use e-mail and chat rooms, and utilizing the information retrieval potential. Parents and teachers surveyed also praised the project, feeling that their students learned more as a result of being involved in project activity. 相似文献

The pigeon’s keypecking response includes both a head-transport (peck) and a jaw-movement (gape) component. Because the two components are mediated by different effector systems, they may potentially be viewed as orthogonal responses. A response differentiation procedure was used to bring gape amplitude under operant control. The procedure employed a conjunctive response requirement in which reinforcement was contingent upon both gaping and key contact. The key-contact requirement was held constant, while the gape contingency was systematically varied to reinforce either decreases or increases in gape amplitude with respect to baseline. The procedure was effective in shifting the gape distributions in both the upward and downward directions and in inducing new gape values that deviated from the baseline in the reinforced direction. These observations indicate that gape may be brought under operant control. However, subjects showed a bias in the differentiation of the gape response, such that larger gapes were more readily differentiated than smaller gapes. The results are discussed in relation to the methodological utility of the paradigm, the problem of biological constraints on learning, and the heuristic utility of a response components analysis. 相似文献

A Prospective Study of Life Stress, Social Support, and Adaptation in Early Adolescence 总被引:9,自引:0,他引:9

This study employed a 2-year longitudinal design to examine the relation of stressful life events and social supports to psychological distress and school performance among 166 early adolescents (mean age = 13.5 years). A prospective approach was utilized to control for initial levels of adjustment when examining the relation of Time 1 stress and support variables to Time 2 psychological distress and school performance. Both stress and support variables made significant contributions to the prediction of subsequent psychological distress. Stresses, but not supports, made a significant contribution to the prediction of subsequent school performance. Evidence for reciprocal and interactive linkages was also found, including effects of psychological distress and school performance on subsequent stresses and supports, and greater adaptive impact of school-based supportive resources under conditions of heightened risk outside of school. Implications for ecological and transactional models of development relating to the targeting and efficacy of preventive efforts are discussed. 相似文献

ABSTRACTTaking full advantage of the educative benefits of interaction in digital learning environments will require the development of new theoretical frameworks that can contribute to a richer understanding of interaction. Literary theory provides an excellent place to develop such a framework and advanced understanding. Literary theory enables us to reconceptualise online courses as ‘texts’, thereby equipping us with more sophisticated modes of analysis for the teaching and learning process. By rethinking online courses as texts, and better yet as what Roland Barthes has described as ‘writerly’ texts, we can improve interaction in the online classroom. More importantly, we can move toward a more meaningful form of interaction, where learners interact with course content at the level of meaning and meaning making, where interaction becomes a full participation in the production of a lesson’s meaning. Indeed, this aim of co-producing meaning should be the primary objective of all learning. 相似文献

A growing body of literature defines a rhetoric of visible text based on page layout, typography, and the various design features afforded by page composition tools buitt into word processors and page design programs. Little has been written, however, about what a wriier needs to know about design and in what order. This article describes and demonstrates a scope and sequence of learning that encourages writers to develop their skills as text designers. It introduces relevant liierature that is helpful for such learning and it does so in an evolving format that displays visually what the essay discusses verbally. 相似文献

Interpreting and creating graphs plays a critical role in scientific practice. The K-12 Next Generation Science Standards call for students to use graphs for scientific modeling, reasoning, and communication. To measure progress on this dimension, we need valid and reliable measures of graph understanding in science. In this research, we designed items to measure graph comprehension, critique, and construction and developed scoring rubrics based on the knowledge integration (KI) framework. We administered the items to over 460 middle school students. We found that the items formed a coherent scale and had good reliability using both item response theory and classical test theory. The KI scoring rubric showed that most students had difficulty linking graphs features to science concepts, especially when asked to critique or construct graphs. In addition, students with limited access to computers as well as those who speak a language other than English at home have less integrated understanding than others. These findings point to the need to increase the integration of graphing into science instruction. The results suggest directions for further research leading to comprehensive assessments of graph understanding. 相似文献

A distinct and complex definition of attitude is evolving within the literature. A mental readiness to respond and a correlational consistency between attitude and behavior—although controversial and in need of further study and analysis—remain viable subcomponents within the definition. Most agree that evaluation is the heartbeat of attitude. The impact of social influence on attitudes is becoming increasingly important. Attitudes are learned and not inherited. 相似文献
