Honeybees foraged from six locations, each of which was baited with sugar solution prior to each experimental trial. Under a variety of conditions, bees exhibited a small but reliable tendency to avoid revisits to locations that they had visited earlier during the experimental trial. These results replicate those of Brown and Demas (1994), who concluded that bees use working memory to discriminate previously visited locations from those not yet visited. The present experiments included procedures that allowed alternatives to this explanation to be more completely ruled out. The extent of spatial working memory performance exhibited by honeybees in these experiments appears to be limited by a process other than working memory capacity, perhaps the ability of bees to discriminate among several locations in close proximity to one another.  相似文献

The concept of “manager as coach” is increasingly popular in the management literature as a mechanism for improving employee involvement and performance. This paper summarizes a study we conducted to evaluate “coaching skills” among sales managers. The study used telephone interviews with managers' subordinates to collect data regarding managers' coaching effectiveness. During the interviews, subordinates rated their supervisors' coaching skills and provided a rationale for their rankings. This study analyzes the ratings and the comments, and outlines the behaviors associated with both high and low ratings of manager coaching skills.  相似文献

The article argues, in relation to Malawi, that curriculum vocationalization of general academic education as a ploy for solving school leavers' unemployment seems more of a myth than a practical reality. In that vocational education costs twice as much as general education, and bearing in mind that there are a number of partially or indeed unmet basic human needs, Malawi may not have enough resources to effectively vocationalize given her relative poverty. And even if there were enough resources, emerging evidence suggests that schools can prepare their pupils for the labour market only to a limited degree because of the variety and frequent changes of occupations. Accordingly, the paper concludes that vocational training should be left to specialist institutions outside general education, and should be employment-based as far as possible.
Zusammenfassung Der Artikel argumentiert, daß in Bezug auf Malawi die berufliche Orientierung des Curriculums der allgemeinen akademischen Bildung als Lösung für die Arbeitslosigkeit von Schulabgängern eher einen Mythos als eine praktische Realität darstellt. Darin kostet Berufsbildung doppelt soviel wie die allgemeine Bildung, und wenn man bedenkt, daß es eine ganze Reihe von teilweise oder überhaupt nicht erfüllten menschlichen Grundbedürfnissen gibt, könnten die Ressourcen Malawis nicht ausreichend sein, um dem Curriculum in Anbetracht der relativen Armut wirkungsvoll einen beruflichen Schwerpunkt zu verleihen. Selbst wenn es genügend Ressourcen gäbe, gibt es neuerdings Anzeichen dafür, daß die Schule ihre Schüler auf Grund der Vielfalt und häufigen Veränderungen der Berufszweige nur bedingt auf den Arbeitsmarkt vorbereiten kann. Dementsprechend schließt der Artikel mit dem Argument, daß berufliche Fortbildung speziellen Einrichtungen außerhalb der allgemeinen Bildung überlassen und so weit wie möglich berufsorientiert sein sollte.

Résumé L'article suggère, sur l'exemple du Malawi, qu'une orientation professionnelle des curriculums dans l'éducation générale supérieure en tant que moyen pour résoudre le chômage des professionnels débutants est davantage un mythe qu'une réalité pratique. Dans la mesure où la formation professionnelle coûte deux fois plus que la formation générale, et sans oublier que trop de besoins fondamentaux ne sont que partiellement ou nullement satisfaits, les ressources du Malawi pourraient être insuffisantes en regard à sa relative pauvreté pour donner avec efficacité un accent professionnel à son système éducatif. Supposant même qu'il en serait le cas, les faits démontrent que les écoles ne peuvent préparer leurs élèves que de façon limitée au marché du travail, en raison de la diversité des formations et du changement fréquent d'activité. L'article conclut donc par l'assertion que la formation professionnelle devrait être confiée à des institutions spécialisées distinctes de celles de la formation générale, et réalisée autant que possible dans les entreprises.

Recent years have seen a substantial growth in research that probes children's ideas about natural phenomena. This article places the research in a context that enables comprehension of how it informs and influences the practice of science education. To this end, past, present, and developing styles of research are discussed. The predominant style of past research was based on elaborate experimental designs and complex statistical analyses of data. Studies employing that style helped focus concern on questions about individual learning which the studies did not actually seek to answer, e.g., why does the learning resulting from a particular treatment vary between individuals? What is understanding and how can it be assessed? Such questions lie at the heart of current probing of children's ideas. Some issues of importance in the probing of children's ideas are considered, as are ways in which these issues have influenced the development of a current style of research. From this present context, developing styles in the research field are described. These focus particularly on research on the strategies used by learners, and on the continued growth of interaction between research and practice.  相似文献

A strong tradition in research in primary and secondary schools has involved student and teacher perceptions of psychological characteristics of actual or preferred classroom environment. This paper provides a foundation for the extension of this tradition to the higher education level by describing the development, validation, and use of a new instrument, the College and University Classroom Environment Inventory (CUCEI), suitable for small higher education classes often referred to as seminars. The CUCEI assesses students' or instructors' perceptions of the following seven psychosocial dimensions of actual or preferred classroom environment: personalization, involvement, student cohesiveness, satisfaction, task orientation, innovation, and individualization. Administration of the CUCEI to 372 students in 34 classes and to 20 instructors attested to the internal consistency reliability and discriminant validity of the actual and preferred forms with either the individual or the class mean as the unit of analysis, and supported the ability of the actual form to differentiate between the perceptions of students in different classrooms. A research application of the CUCEI involving associations between student outcomes and classroom environment tentatively suggested that the nature of the classroom environment affects outcomes. Another research application suggested that both students and instructors preferred a more favorable classroom environment than the one actually present, and that instructors viewed classroom environments more positively than did their students in the same classrooms. Desirable future applications of the CUCEI for research purposes and in improving teaching in higher education are considered.The first main aim of this paper is to describe the development and validation of a new instrument to assess perceptions of classroom psychosocial environment in university and college classrooms. The second major purpose is to report the first two research uses of this instrument in, respectively, a study of associations between student outcomes and classroom environment and an investigation of differences between students and instructors in their perceptions of actual and preferred classroom environment. As well, desirable future research directions involving the new instrument are suggested. Before describing the development and use of the new instrument for the higher education level, important background information about analogous work at the primary and secondary school levels is briefly reviewed in an attempt to place the new work into context.  相似文献

As part of a large scale mathematics study, students were asked to make up a mathematics problem that would be difficult for a friend to solve. They were also asked to solve the problem themselves. A sub-sample of 11- to 13-year-olds was interviewed while they worked through the items in the study.The problems made up by a group of eight more able and eight less able children from this sub-sample are reported here, together with the comments the children made during the interviews about their respective problems.The results highlight features of the problems made up by the two groups of children. In general, the more able children made up problems of greater computational difficulty, with more complex number systems and with more operations than their less able peers. In addition, there is evidence to suggest that the more able students planned their problems and were able to work out the answer, while their less able peers had difficulty with both the planning and the solution of their own problems.As the substance and style of the problem made up by each child uniquely reflects that child's mathematical experiences and ideas, the made up problem is a particularly useful tool for studying mathematically talented children for whom routine tasks are usually completed quickly and accurately.  相似文献
