John Halliday 《Educational Research and Evaluation》2013,19(4):351-365
Abstract Recently in the UK, there has been an attempt to ensure quality in the education system through policies that encourage standardisation in teaching practice. In this article it is argued that quality in education systems should be promoted through diversity in practice sustained by a tradition of good teaching. It is argued that teaching is characterised by a degree of scepticism about practice that cannot be avoided through the use of standard curriculum materials, national curricula, objectives or anything else. Some implications for educational evaluation are drawn from this argument. 相似文献

Abstract This article reviews the Hong Kong policy (1998) on information technology in education (ITE). Key proposals in the policy and the rationales presented for introducing new technology in schools are examined. It is suggested that initiatives presented would have been difficult to implement fully without more far-reaching changes in education policies and school practices. Now, other proposals for reform of education in Hong Kong have been released. The ways in which these recent proposals for reform support existing initiatives in ITE are identified and discussed. Available data on the implementation of ITE are also reviewed. It is suggested that while a comprehensive policy framework has now been developed, the ‘vision’ for ITE may take some time to be realised. 相似文献

We present evidence on productivity improvement experienced by the research institutes of the Chinese Academy of Sciences (CAS) after its implementation of the Knowledge Innovation Program (KIP). Using a balanced panel of data on R&D inputs and outputs of 59 research institutes in CAS, we analyze the productivity, technological and efficiency changes from 1997 to 2005. We document that the CAS research institutes have a productivity growth of 12.5% from 1998 to 2005, which can be further decomposed into 8.8% attributed to technological progress and 3.3% to efficiency improvement. Results of regional analysis show that institutes in Beijing and Shanghai, performed better than institutes in other regions during the same period. 相似文献

The Course-Faculty Instrument (CFI) demonstrates similar measurement properties with student populations at four diverse institutions. These students agree about the nature and extent to which course and instructor attributes relate to their learning. The results suggest that: (1) a perceived learning criterion may have general relevance to students, and (2) validity extension research is an economically feasible alternative to full-scale instrument development and validation efforts. Since validity extension is practical and facilitates cross-institutional comparisons, it appears to be a more viable strategy for researching and instituting student evaluation systems than is suggested by its current usage. 相似文献

John Tillson 《Educational theory》2017,67(2):173-191
Michael Hand has defended the “epistemic criterion” for “directive and nondirective teaching” in his 2008 Educational Theory article, “What Should We Teach as Controversial? A Defense of the Epistemic Criterion,” as well as subsequent pieces. Here, John Tillson defends use of the epistemic criterion in the case of what he calls “momentous propositions,” but he rejects two of Hand's key arguments in support of the criterion. This rethinking comes in light of important contributions to the debate made by Bryan Warnick and D. Spencer Smith and by Maughn Rollins Gregory, also published in this journal. Tillson begins the article with an elucidation of the directive/nondirective distinction, and then discusses some limitations of defining the distinction in terms of intention. Next, he draws attention to the problems with the “soft‐directive teaching” method that Warnick and Smith advocate. Finally, Tillson provides an additional argument in favor of the epistemic criterion, an argument also grounded in work by Hand, which places emphasis on imparting knowledge alongside cultivating rationality among our educational aims. 相似文献

Explaining the academic performance of community college students who transfer to a senior institution 总被引:1,自引:1,他引:1
Archie G. Phlegar Loyd D. Andrew Gerald W. McLaughlin 《Research in higher education》1981,15(2):99-108
The academic performance of 361 community college students was investigated after their transfer to a comprehensive university. The predictor variables included personal, environmental, demographic, and pretransfer academic measures. The criterion was grade point average (GPA) at the senior institution. Analyses included moderated linear regression and a branching algorithm which forms subgroups to best explain criterion scores (AID-3). The academic pattern and performance at the community college was found to be very important to the relevance of specific factors related to the curriculum selected at the senior institution. 相似文献

In human infancy, 2 criteria for intentional communication are (a) persistence in and (b) elaboration of communication when initial attempts to communicate fail. Twenty-nine chimpanzees (Pan troglodytes) were presented with both desirable (a banana) and undesirable food (commercial primate chow). Three conditions were administered: (a) the banana was delivered (successful communication), (b) half of the banana was delivered (partially successful communication), and (c) the chow was delivered (failed communication). The chimpanzees exhibited persistence in and elaboration of their communication in every condition except when the banana was delivered. Thus, their communication was about a specific item, demonstrating that both intentionality and nonverbal reference are capacities shared by humans with our nearest living relatives, the great apes. 相似文献

A high ambient temperature reduces the capacity to perform prolonged exercise. Total carbohydrate oxidation is less, and thus glycogen depletion is not limiting. Fluid ingestion in the heat should, therefore, focus on maintenance of hydration status rather than on substrate provision. Six healthy males cycled to exhaustion at 60% of maximum oxygen consumption (VO 2max ) with no drink, ingestion of a 15% carbohydrate-electrolyte drink (1.45 - 0.29 litres) or ingestion of a 2% carbohydrate-electrolyte drink (3.12 - 0.47 litres). The ambient temperature was 30.2 - 0.6°C (mean - s ), with a relative humidity of 71 - 1% and an air speed of approximately 0.7 m.s -1 on all trials. Weighted mean skin temperature, rectal temperature and heart rate were recorded and venous samples drawn for determination of plasma volume changes, blood metabolites, serum electrolytes and osmolality. Expired gas was collected to estimate rates of fuel oxidation. Exercise capacity was significantly ( P ? 0.05) different in all trials. The median (range) time to exhaustion was 70.9 min (39.4-97.4 min) in the no-drink trial, 84.0 min (62.7-145 min) in the 15% carbohydrate trial and 118 min (82.6-168 min) in the 2% carbohydrate trial. The 15% carbohydrate drink resulted in significantly ( P ? 0.05) elevated blood glucose and total carbohydrate oxidation compared with the no-drink trial. The 2% carbohydrate drink restored plasma volume to pre-exercise values by the end of exercise. No differences were observed in other thermoregulatory or cardiorespiratory responses between trials. These results suggest that fluid replacement with a large volume of a dilute carbohydrate drink is beneficial during exercise in the heat, but the precise mechanisms for the improved exercise capacity are unclear. 相似文献
