The article reviews different views of creativity, building on the work of Czikszentmihaly. It offers a definition of creativity in terms of trait/process/product. The issue of how creativity might be assessed is explored using this definition and some illustrative examples are provided. The article concludes that creativity can and should be assessed but that this must be with an appropriate methodology. Such assessment is important not only for assessing students' work but also for evaluating curriculum content, in order to promote curriculum development in the teaching of creativity.  相似文献

Decision-making is a key component of an umpire’s in-game performance, with each decision potentially having a direct impact on the result of the game. Additionally, umpires have to be physically fit to ensure they keep up with the gameplay. While research has identified the decision-making demands and running demands of umpires separately, few have explored the relationship between them. The aim of this investigation was to examine the relationship between physical exertion and decision-making performance of Australian football umpires at the sub-elite and junior levels. A total of 18 Australian football umpires (sub-elite, n = 10; junior n = 8) performed 10 × 300 m runs, with each repetition immediately followed by a video-based decision-making test, then 1 min of recovery. A Mann–Whitney U assessment indicated a significant difference between the sub-elite and junior level umpires for decision-making accuracy (U = 13.00, = ?2.43, P = 0.016, r = ?0.5). However, there was no significant difference in response time (U = 28.00, z = ?1.07, P = 0.315, r = ?0.25). The sub-elite umpires completed the running efforts in significantly less time than the junior umpires (P < 0.05). Further, there was no significant correlation between decision-making performance and running times for either skill level (P > 0.05). This suggests decision-making performance may not be affected by physical exertion. Therefore, it may be suggested coaches of football umpires allocate more time to the decision-making development of their umpires instead of focusing largely on the physical fitness side, as is currently the trend.  相似文献

At the foreground of this article is an account of an experienced science teacher's self-initiated change in praxis within an inquiry community. From classroom observation and interviews, data interpretations are made about the discursive practices of the teacher and his colleagues. In particular, the teacher's change in praxis is attributed to his dissatisfaction with previous practice, realization that alternatives were likely to provide better outcomes for his students, commitment to improving his practice, and a supportive school community in which teachers felt comfortable taking personal risks and engaging in professional discussions. The collaborative culture of the study site was characterized by the teachers' caring ethic for their students.  相似文献

Abstract: This research describes the outcome of a needs assessment to determine whether the Univ. of Guyana should introduce a Food Science program. The research design utilized interviews and questionnaires to large manufacturing organizations and agroprocessors to determine if the required skills are available for the manufacturing process. Results revealed that the lack of skills, particularly in food processing, is one factor that has negatively impacted value‐added production in large manufacturing companies; as well as in the micro, small and medium enterprises, limiting the range of products produced by these entities. Based on this, it was established that the university should introduce a program in food science and be the focus for formal training to satisfy the demands of the food manufacturing industry.  相似文献

The purpose of this study is to examine the social and self-perceptions of twice-exceptional students, those students who meet criteria for being identified as both gifted and learning disabled. In particular, we focus on how twice-exceptional students are similar to, or different from, students with only a learning disability or who are only identified as gifted. Using data collected from the National Longitudinal Study of Adolescent Health, we identified a group of 90 twice-exceptional adolescents as well as three matched comparison groups. Overall, twice-exceptional adolescents had less positive perceptions of maternal relationships and self-concept than did gifted or nonidentified adolescents. Further, perceptions of maternal relationships mediated and moderated group differences in self-concept. Implications for adults working with twice-exceptional adolescents are discussed.  相似文献

ABSTRACT

We study the developmental and professional activities engaged in by 86 female adult soccer players from the senior national teams of Australia, Canada, England, Sweden, and the United States of America. Players completed the Participation History Questionnaire (PHQ) to elicit the amount and type of activities engaged in across their developmental and professional years, including milestones, soccer-specific activity and engagement in other sport activity. Greater specialisation than diversification characterised their childhood developmental activities, including all players starting in soccer in childhood and accumulating more hours in soccer activity than other sports during this period. However, interindividual variation further characterised these childhood activities, with a proportion of players diversifying into other sports and/or soccer play to a greater or lesser degree during childhood when compared to the other players. The amount of coach-led soccer practice increased for all players across their development culminating in an average of 15–16 h/wk across a 40-week season in early adulthood. In contrast, the amount of engagement in other sports and soccer peer-led play varied between players but generally decreased across adolescence to negligible amounts in late adolescence. Findings are commensurate with the deliberate practice framework and early engagement.  相似文献
