The differences, so far as Yugoslav legislation is concerned, between “equivalence” and “recognition” are mads clear, and the Yugoslav instances authorized to make decisions on questions of equivalence and recognition are stated and their procedures, briefly described. The 7 multilateral conventions and the 13 bilateral agreements on equivalence and recognition matters are listed. More is said about the various Yugoslav instances empowered to make decisions and to give Information on questions of equivalence and recognition.  相似文献

The AGIRE project, under the Edulab concept, aims to promote the adoption of innovative teaching practices. This paper reports the support strategies used to evaluate the teacher practices at the end of a teacher training course (TTC) and analyse its impact on teacher technology integration, using a design-based methodology. Teachers’ initial perception was gathered using an online questionnaire comprising ICT personal and professional competencies. The questionnaire results and the classroom observations showed that the majority of teachers were at the level of ICT adoption, before attending the TTC, reaching the adaptation level of integration of ICT, after the TTC. A variety of teaching strategies (flipped classroom, collaborative work, …) and technologies (interactive white boards, tablets, videos, …) were explored. The results sustain the thesis that, with proper support, ICT can be integrated in educational contexts in an innovative way and contribute to the development of teachers’ digital literacy.  相似文献

Despite its frequent use, there is little understanding of the concept of differential among upper high school and undergraduate students of physics. As a first step to identify the origin of this situation and to revert it, we have done a historic and epistemological study aimed at clarifying the role and the meaning of the differential in physics and at improving curricular and teaching models in the sense of Gilbert et al. (Gilbert J.K., Boulter C., & Rutherford, M.: 1998a, International Journal of Science Education 20(1), 83–97, Gilbert J.K., Boulter C., & Rutherford, M.: 1998b, International Journal of Science Education 20(2), 187–203). We describe the contributions of Leibniz and Cauchy and stress their shortcomings, which are overcome by the alternative definition proposed by the French mathematician Fréchet, dating from early 20th century. As a result of this study, we answer to some fundamental questions related to a proper understanding of the differential in physics education (for 17–19 years old students).  相似文献

Factors affecting probabilistic judgements in children and adolescents   总被引:1,自引:0,他引:1  
Six hundred and eighteen pupils, enrolled in elementary and junior-high-school classes (Pisa, Italy) were asked to solve a number of probability problems. The main aim of the investigation has been to obtain a better understanding of the origins and nature of some probabilistic intuitive obstacles. A linguistic factor has been identified: It appears that for many children, the concept of certain events is more difficult to comprehend than that of possible events. It has been found that even adolescents have difficulties in detaching the mathematical structure from the practical embodiment of the stochastic situation. In problems where numbers intervene, the magnitude of the numbers considered has an effect on their probability: bigger numbers are more likely to be obtained than smaller ones. Many children seem to be unable to solve probability questions, because of their inability to consider the rational structure of a hazard situation: chance is, by itself, an equalizing factor of probabilities. Positive intuitive capacities have also been identified: some problems referring to compound events are better solved when addressed in a general form than when addressed in a particular way.  相似文献

AIMS AND OBJECTIVES: The study evaluates the Community Outreach Library Service at Wirral Hospital National Health Service Trust (WHNT). It considers the information seeking behaviour and information needs of primary care staff, and service effectiveness in meeting those needs. METHODS: A literature review established the current context and areas of best practice. The investigative case study used postal questionnaires to 250 primary care staff and an interview with the Community Outreach Librarian. FINDINGS: Themes emerged from the literature regarding information seeking behaviour, information needs, and meeting user needs through effective service delivery. Outreach services have value in terms of improving information skills and providing services at point of need. Time is a major constraint for both users and service providers. CONCLUSIONS: Investment is needed from appropriate funding sources to support the provision and marketing of outreach library services. Librarians benefit from sharing best practice. The continued evaluation of outreach library services is recommended.  相似文献

ABSTRACT:   This paper argues for an action-oriented conception of learning in higher education: one which marries higher order learning (coming to understand) with apprenticeship in knowledge work. It introduces epistemic tasks, forms and fluency as constructs that are useful in giving a more precise meaning to ideas about collaboration in knowledge construction. Discussion is seen as central to collaborative knowledge work and we examine the role of discussion in supporting weaker and stronger interpretations of collaborative knowledge construction.  相似文献

This article examines how 31 triads of 6- to 10-year-old children from 3 cultural backgrounds organized their interactions while folding Origami figures. Triads of children whose families had immigrated to the United States from indigenous heritage regions of México (and whose mothers averaged only 7 grades of schooling) coordinated more often as an ensemble, whereas triads of European heritage U.S. children whose mothers had extensive schooling more often engaged dyadically or individually. When the European heritage children did engage as an ensemble, this often involved chatting rather than nonverbal conversation regarding folding, which was more common among the Mexican heritage children. Mexican heritage U.S. triads whose mothers had extensive schooling showed an intermediate pattern or resembled the European heritage children.  相似文献

The aims of this study were (a) to determine whether Spanish children with reading disabilities (RD) show a speech perception deficit and (b) to explore the locus and nature of this perceptive deficit. A group of 29 children with RD, 41 chronological age-matched controls, and 27 reading ability-matched younger controls were tested on tasks of speech perception. The effect of linguistic unit (word vs. syllable) and type of phonetic contrast (voicing, place and manner of articulation) were analyzed in terms of the number of errors and the response time. The results revealed a speech perception deficit in Spanish children with RD that was independent of the type of phonetic contrast and of linguistic unit.  相似文献
