Constructivist Metaphors of Learning Science 总被引:2,自引:1,他引:2
Based on an analysis of a fundamental distinction between metaphors of finding versus making for the obtaining of new knowledge, a number of constructivist positions in education are discussed and criticised, taking account of earlier criticism particularly by Suchting and by Matthews. Constructivist claims which are denied include the claim that we have no direct access to the world, and the claim that communication is inherently meaningless. What is valuable in constructivism, namely the insistence on active learning, on respect for the pupils own thinking, and on the high priority needed for ideas taught to make sense to pupils, together with the reminder that science is a human product, is important to retain without its additional and ill-founded philosophical baggage. 相似文献

The paper presents findings from an evaluation of ‘industrial education’ subjects (wood, metal, electrical and power technology) in Kenyan academic secondary schools. As a project established in 35 schools with comprehensive aid agency (SIDA) support, these subjects do not suffer from lack of attraction to students or from low teacher morale. Exposure to them increases students' aspirations and expectations of ‘technical/practical’ work, but the problem is not lack of interest in such work, but rather scarce opportunity to realise such ambition, in a labour market where school leavers face great problems in finding a source of livelihood. Except for individual cases, exposure to these subjects does not seem to give students an advantage in the labour market, according to findings from a one-year follow-up. Further, doing well in general on the lower secondary examination does not confer any short-term labour market advantage either, suggesting that personal contacts rather than school credentials are decisive. We conclude policy makers need to recognise that pre-vocational subjects should be seen as part of general education rather than as a remedy for youth unemployment. 相似文献

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster. 相似文献

Although the effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy have been investigated in several studies, the findings are equivocal and the practical implications remain unclear. In an attempt to provide clarity on the topic, we performed a systematic literature search of PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library, and Physiotherapy Evidence Database (PEDro) electronic databases. Six studies were found to have met the inclusion criteria: (a) an experimental trial published in an English-language peer-reviewed journal; (b) the study compared the use of short (≤60?s) to long (>60?s) inter-set rest intervals in a traditional dynamic resistance exercise using both concentric and eccentric muscle actions, with the only difference in resistance training among groups being the inter-set rest interval duration; (c) at least one method of measuring changes in muscle mass was used in the study; (d) the study lasted for a minimum of four weeks, employed a training frequency of ≥2 resistance training days per week, and (e) used human participants without known chronic disease or injury. Current evidence indicates that both short and long inter-set rest intervals may be useful when training for achieving gains in muscle hypertrophy. Novel findings involving trained participants using measures sensitive to detect changes in muscle hypertrophy suggest a possible advantage for the use of long rest intervals to elicit hypertrophic effects. However, due to the paucity of studies with similar designs, further research is needed to provide a clear differentiation between these two approaches. 相似文献

10年前,几乎所有人都相信网球的未来将被会大力发球的巨人主宰,但现在卡洛维奇和埃斯纳都还是二流选手,这当中到底发生了什么?有人开玩笑说:男子网球有三条铁律。第一,所有时代的伟大选手都有一手漂亮的单反,第二,他们都有一个贤内助(米尔卡?但布里吉特也算吗?),第三,他们都有炮弹发球。这里面听起来比较靠谱的仅仅是发球,作为全世界最好的选手和全世界最高的选手费德勒和卡洛维奇,我们可以拿他们的二十项技术指标做比较,卡洛维奇只有一项技术指标可以超过费德勒,那就是发球,这就使得卡洛维奇有机会在任何时候和费德勒较量一番,这就像拳击手有致命的重拳,网球选手有发球,就有了机会。 相似文献

ABSTRACTWith the publication of DSM-5, clinical assessment of Autism Spectrum Disorder (ASD) has begun to follow a new dimensional framework which includes new severity specifiers. Little research has explored these severity ratings in comparison to other previously established severity indicators (e.g. ADOS-2 calibrated severity score). The current study compared parent and teacher ratings using the BASC-2 for 43 children and adolescents diagnosed with DSM-5 ASD, to contribute novel information to the BASC literature and to explore the new DSM-5 severity ratings. Linear regression analyses were conducted to determine the extent to which the DSM-5 Social Communication and Restrictive/Repetitive Behavior Severity Ratings (clinician-rated) predicted autism severity based on ADOS-2 calibrated severity scores. Furthermore, linear regressions were conducted to explore whether teacher ratings on the BASC-2 enhance parent ratings. Implications of these preliminary results for the assessment of children and adolescents with ASD are suggested. 相似文献
