The identity of the worker foregrounds the development of higher education rather than the other way around. It is developed in contrast to the lack of higher education innovation in the recent UK Government White Paper on Higher Education and in the educational philosophy of Tawney and the neo‐pragmaticism of Rorty. The proposal is that higher learning, after capabilities have been nurtured in compulsory schooling, may be developed through communities of workers acting as agent for improvement of their communities; not in universities at all. This is a radical approach to higher education and employment and one that might bring true diversity to the higher education sector. 相似文献

This 2‐year longitudinal study examined both concurrent and longitudinal relations of a variety of reading‐related cognitive tasks and Chinese word reading and word dictation among 187 Hong Kong Chinese kindergarteners aged 4–6. Homophone awareness, visual skills and syllable awareness were all uniquely associated with Chinese word reading across time, with age, vocabulary knowledge and nonverbal IQ statistically controlled. Only visual skill and syllable deletion uniquely explained early Chinese word dictation, however. Results extend previous research on cognitive correlates of Chinese literacy and highlight the small but unique contribution of homophone awareness for early reading acquisition in Chinese. 相似文献

Lead is found in small but appreciable quantities in air, soil drinking water and food. Exposure to such amounts of lead does not cause acute lead toxicity, but produces subtle effects, particularly in children. The CDC advocates “safe” or “acceptable” levels of blood lead up to 10 μg/dl, while OSHA declares blood lead levels up to 40 μg/dl as “safe” or “acceptable” in the occupationally exposed. The objective of the study was to see if blood levels considered “safe” can cause changes in the biogenic neurotransmitters in the developing brain which may cause neurobehavioral defects like hyperactivity and other cognitive disorders. Albino Wistar rats were divided into the control and lead-treated groups. The control group was given unleaded water, while the lead-treated group was fed with 50 ppm lead acetate in drinking water. On day 45 the animals were subjected to a passive avoidance test, their blood analysed for ZPP and lead. They were then sacrificed and the neurotransmitters—Norepinephrine (NE) and its metabolite—methoxyhydroxyphenylglycol (MHPG) estimated in the brain areas associated with learning and memory—the frontal cortex, hippocampus and the striatum by HPLC-ECD. Our results showed significant increases in blood lead, NE and MHPG, while ZPP increase was insignificant. The rats showed neurobehavioral abnormalities as assessed by the passive avoidance test. We concluded that low blood levels of lead cannot be considered “safe” or “acceptable” as it causes neurotransmitter alterations. Increased NE turnover is implicated in hyperactivity disorders such as ADHD and Tourette syndrome. 相似文献

There is considerable variation between male and female Bachelor degree performance at Oxford and Cambridge (Oxbridge) where male students attain more First and Third Class degrees and female students attain more Second Class degrees. Various hypotheses have been put forward to explain this phenomenon including the possibility that the distinctive Oxbridge assessment environment, very different from those at both pre‐ and post‐92 universities, might account for the difference. Data from the Assessment Experience Questionnaire (AEQ; Oxbridge, pre‐ and post‐92 universities, one science, one humanities and one applied social science subject from each) were analysed to determine gendered perceptions of the assessment environment. Significant gender differences were found on five AEQ scales (Quantity of effort, Coverage of syllabus, Quantity and quality of feedback, Use of feedback and Appropriate assessment) but there was no significant interaction between gender and university. Consequently, there were few clues in students' responses to confirm that the Oxbridge assessment environment explains gendered differences in degree performance. 相似文献

This paper considers the implications of mentoring for the discursive formation of professional identities of newly graduated teachers. The site for this analysis is the Teacher Mentoring and Induction Program, in Victoria, Australia. The paper draws attention to the effects of mentoring as conceived in this context on the construction of new teacher identities, the close relationship between professional standards and mentoring, the relationship between mentoring and the performative culture of schools, and what it means to be ‘a good teacher’ within this culture. The aim is to reposition mentoring as a product of its contexts and times, and in so doing contribute to the development of a more theoretically informed and critical platform from which to conduct research into its effects and benefits. 相似文献

The aim of this study was to develop a model to evaluate the retrieval quality of search queries performed by Dutch general practitioners using the printed Index Medicus, MEDLINE on CD-ROM, and MEDLINE through GRATEFUL MED. Four search queries related to general practice were formulated for a continuing medical education course in literature searching. The selected potential relevant citations from the course instructor and the 103 course participants together served as the basic set for the three judges to evaluate for (a) relevance and (b) quality, with the latter based on journal ranking, research design and publication type. Relevant individual citations received a citation quality score from 1 (low) to 4 (high). The overall search quality was expressed in a formula, which included the individual citation quality score of the selected and missed relevant citations, and the number of selected non-relevant citations. The outcome measures were the number and quality of relevant citations and agreement between the judges. Out of 864 citations, 139 were assessed as relevant, of which 44 citations received an individual citation quality score of 1, 76 of 2, 19 of 3 and none of 4. The level of agreement between the judges was 68% for the relevant citations, and 88% for the non-relevant citations. We describe a model for the evaluation of search queries based not only on the relevance, but also on the quality of the citations retrieved. With adaptation, this model could be generalized to other professional users, and to other bibliographic sources. 相似文献

This study is an attempt to contribute to the growing body of knowledge about students' conceptions and views concerning environmental and natural resource issues. Answers have been sought to the following questions: “How do Swedish students in grade 9 (15–16 years old) and grade 12 (18–19 years old) explain the greenhouse effect?”, “How do they think reduction of CO2 emission would affect society?” and “How do they explain that the depletion of the ozone layer is a problem?” The method chosen to answer these questions was to give students written tasks of the open‐ended type. Five models of the greenhouse effect appear among the answers, all more or less incomplete, but nevertheless with potential for development. The students' responses also indicate that they do not fully understand what fundamental societal changes would occur as a result of a drastic reduction in CO2 emission. On the other hand, they are rather well informed about how injurious depletion of the ozone layer is to humans. The findings are discussed, including implications for teaching. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 1096–1111, 2000 相似文献
