In this interview, Dr. Kimmo Lehtonen discusses the current “state of the art” regarding creativity in Scandinavia, Europe, and around the world. He explores the training of teachers, prodigies, and art and music therapy. Dr. Lehtonen examines the issue of computers relative to creativity and various theoretical explanations for the phenomenon of creativity. Personality factors are examined and explored, and future concerns are delineated. 相似文献

Conclusion This paper has been concerned with the application of basic understandings about intrinsic motivation and curiosity behaviour
to the teaching of science, and in particular senior high school biology. The important role of student knowledge in the generation,
maintenance and resolution of cognitive conflict is congruent with the renewed interest in studying students' everyday knowledge
of curriculum content. However the study of classroom teaching processes in terms of their facilitation of intrinsic motivation
is not common. Yet the data collected in this study demonstrates the importance of closely examining the implementation of
courses such as the Web of Life, if the arousal of intrinsic motivation is an intended student outcome. Both interview and
observational data indicated that the teaching styles adopted by teachers in this study were not likely to engender curiosity
amongst students. Perhaps this should be expected. The use of a wide range of reference materials to investigate problems
that arise in the classroom, the encouragement of students to do additional work on a topic if they are particularly interested,
and a willingness on the part of the teacher to allow students sufficient time to formulate their own solutions to problems
are classroom processes which necessitate a greater flexibility in curriculum presentation than can be often tolerated by
teacher and school management. Such processes may be incompatible with organisational properties of the school and the pressures
often placed upon students to perform to a high standard on rigidly defined examinations. 相似文献

The effects of changing pace on metabolism and stroke characteristics during high-speed breaststroke swimming 总被引:1,自引:0,他引:1
Performances often vary between the heats and finals of breaststroke swimming competitions possibly because the swimmers try to conserve their energy, or for other tactical reasons. Additionally, coaches might advise either a 'positive' or 'even' pace race strategy during the final. The effect of such pacing changes on metabolism (blood lactate, heart rate, ventilation), ratings of perceived exertion, stroke kinematics and turning times have not been investigated. Nine male competitive breaststroke swimmers swam three paced (Aquapacer) 200-m trials, 48 h apart and in random order, at 98%, 100% and at an attempted 102% of their maximal 200-m time-trial speed. Responses in metabolic variables were similar between the 98% and 100% trials, but higher post-exercise blood lactate concentrations and respiratory exchange ratios were observed following the 102% trial. As the pace of trials increased, stroke rate was found to increase proportionately with stroke count. However, during the latter stages of the 100% trial, a disproportionate increase in the stroke count was observed, which led to a significant pacing error. This feature was more obvious in the 102% trial, where participants demonstrated 'positive pacing' and reported higher ratings of perceived exertion than for the 98% trial. During the early stages of the trials, turning times were initially shorter the faster the pace of the trial; however, as the trials progressed, this pattern was found to reverse. We conclude that a slight reduction in pace during near maximal breaststroke swimming altered kinematic but not post-exercise metabolic responses, while an increase in pace led to positive pacing and an increase in both kinematic responses and anaerobic metabolism. 相似文献

Mass media campaigns are conducted to influence community norms around health behaviours, including physical activity. Campaigns can reach large populations at relatively low cost, to influence awareness, knowledge and beliefs through to intention and behaviour change. We reviewed 15 campaigns with an explicit focus on physical activity, and explored impacts upon a range of proximal and distal variables. Campaigns achieved high recall, with a median of 70% of the target group aware of the campaign. Increases in knowledge or attitudes to physical activity were found among half the campaigns that reported this measure. Few campaigns reported other proximal variables, such as saliency, beliefs, self-efficacy or behavioural intention. Increases in physical activity were reported among motivated sub-groups of volunteers, but few campaigns reported population increases in activity. Campaigns increase awareness of the issue of physical activity but may not have a population-level effect on behaviour. Campaigns should focus more on influencing proximal variables, such as social norms, to bring about long-term behaviour change. This should be seen as part of a broader strategy, including policy and environmental change. Evaluation designs that measure the full range of variables are preferred to an over-concentration on behaviour alone. 相似文献

Objective: To develop an explicit scheme for calculating a 5‐star quality rating for consumer health information, and to test if there is good agreement be tween this and the final DISCERN quality question. Design: A sample of 15 consumers and health professionals rated 26 health information leaflets covering a broad range of conditions and treatments using two new 5‐star‐rating schemes and the existing DISCERN final quality rating. Each scheme is based on the 15 DISCERN criteria, but the 5‐star schemes provide more explicit methods for summarizing overall quality. The level of agreement between the three different rating systems was compared using Kappa scores with quadratic weights. Participants were also asked to complete a brief questionnaire that was designed to elicit their views on using a visual summary of the quality of health information. Results: The level of agreement between each 5‐star‐rating system and the existing DISCERN quality rating question was high (kappa = 0.86, 95% CI 0.83–0.89 in both instances). Seventy‐seven per cent of the sample preferred the second star‐rating scheme, and 80% reported they would use such a scheme. Conclusion: Assigning a single quality score using an explicit scoring scheme (represented by stars) based on answers to the DISCERN questionnaire is a reliable and valid way of rating consumer health information. 相似文献

Lay perceptions of collectives (e.g., groups, organizations, countries) implicated in the 2009 H1N1 outbreak were studied. Collectives serve symbolic functions to help laypersons make sense of the uncertainty involved in a disease outbreak. We argue that lay representations are dramatized, featuring characters like heroes, villains and victims. In interviews conducted soon after the outbreak, 47 Swiss respondents discussed the risk posed by H1N1, its origins and effects, and protective measures. Countries were the most frequent collectives mentioned. Poor, underdeveloped countries were depicted as victims, albeit ambivalently, as they were viewed as partly responsible for their own plight. Experts (physicians, researchers) and political and health authorities were depicted as heroes. Two villains emerged: the media (viewed as fear mongering or as a puppet serving powerful interests) and private corporations (e.g., the pharmaceutical industry). Laypersons' framing of disease threat diverges substantially from official perspectives. 相似文献

Cultures of Undergraduate Teaching at Research Universities 总被引:2,自引:0,他引:2

Teaching-oriented faculty have received scant attention as a distinctive cultural force. Even among those who would speak on their behalf, undergraduate teachers have been treated as little more than a dependable workforce whose interests are best served by top-down proposals for enhanced recognition and reward. Findings from a five-campus study suggest a more complex reality. Of particular interest is an explicitly oppositional culture that questions both the Scholarship of Teaching model and the ethos of competitive achievement. These views echo the longstanding populist tradition within American higher education and represent a potential counterforce to the recent narrowing of faculty roles. 相似文献
