Two studies examined the relationships between measures of intelligence, personality and divergent thinking (DT) in student samples. Study one investigated the incremental validity of measures of IQ and fluid intelligence with the Big Five Personality Inventory with regards to DT. Significant relationships of DT to fluid intelligence, Extraversion and Disagreeableness were observed. Study two investigated the incremental validity of measures of fluid and crystallised intelligence (as assessed by a test of general knowledge) with the Big Five Personality Inventory with regards to DT. Hierarchical regression analyses revealed a significant relationship between crystallised intelligence and DT. The nature of the relationships of IQ, fluid and crystallised intelligence, in addition to personality traits to tests of DT were considered.  相似文献

According to PIRLS 17 % of German parents choose a non-recommended secondary school-type for their child. Only few empirical studies try to identify parental characteristics related to their rejection of a school-type recommendation from their child’s teacher. Based on the sociological rational choice theory, research primarily focuses on characteristics of social background and on cost-benefit considerations. In addition to this, the present study analyzes to what extent parental evaluation and attribution of the child’s achievement and the appraisal of the primary school’s advice influence the probability of parents’ rejection of the recommendation. The focus of this investigation is on parents whose educational aspirations and choices of school are higher than the teachers’ recommendations. By means of logistic regression we analyze, how well parental decision-making – i. e. adopting the teacher’s recommendation vs. insisting on own, non-compliant opinion – can be predicted by theory-based independent variables. Avoidance of a loss in educational status, parental knowledge of the school system and the perceived quality of a primary school’s advice are revealed to be significant predictors of this rejection.  相似文献

Drawing on the work of Dewey, we present a view of science education from the perspective of art and aesthetics. This perspective places a transformative, aesthetic experience at the forefront of educational objectives. Such experience involves the application of learning in everyday contexts, expansion of perception, and development of an increased interest in science ideas and aspects of the world illuminated by those ideas. We present a pedagogical model focused on fostering transformative, aesthetic experiences. This model involves two general categories of instructional methods: (a) methods of crafting ideas out of concepts, and (b) methods of modeling and scaffolding transformative, aesthetic experiences. We discuss how the methods comprising this pedagogical model relate to established science education methods.  相似文献

The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6–10%). However, both groups increased 0–10 m sprint times (experimental group = 6%; control group = 3%) while 10–20 m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0–10 m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training.  相似文献

Paralympic throwing events for athletes with physical impairments comprise seated and standing javelin, shot put, discus and seated club throwing. Identification of talented throwers would enable prediction of future success and promote participation; however, a valid and reliable talent identification battery for Paralympic throwing has not been reported. This study evaluates the reliability and validity of a talent identification battery for Paralympic throws. Participants were non-disabled so that impairment would not confound analyses, and results would provide an indication of normative performance. Twenty-eight non-disabled participants (13 M; 15 F) aged 23.6 years (±5.44) performed five kinematically distinct criterion throws (three seated, two standing) and nine talent identification tests (three anthropometric, six motor); 23 were tested a second time to evaluate test–retest reliability. Talent identification test–retest reliability was evaluated using Intra-class Correlation Coefficient (ICC) and Bland–Altman plots (Limits of Agreement). Spearman’s correlation assessed strength of association between criterion throws and talent identification tests. Reliability was generally acceptable (mean ICC = 0.89), but two seated talent identification tests require more extensive familiarisation. Correlation strength (mean rs = 0.76) indicated that the talent identification tests can be used to validly identify individuals with competitively advantageous attributes for each of the five kinematically distinct throwing activities. Results facilitate further research in this understudied area.  相似文献

This paper takes a preliminary look at the hybridization of museums – the creation of a variety of mixed forms of governance incorporating both public and private governing authorities. Using data from three national surveys of American museums, the analysis documents the mix of types of governing authority and demonstrates how this mix varies across location, over time, and by museum type. The paper then estimates the extent of hybridization using several different indicators and speculates about its implications. The United States offers a particularly informative case because the general view is that American museums are (1) either public or private and (2) predominately private. While the second part of this view may still be a useful characterization of American museums, the first is no longer a particularly helpful way of understanding American museums, or, by extension, other cultural institutions, American or not. It is increasingly necessary to view cultural institutions through the lens of hybridization rather than privatization in order to improve our ability to document and predict their institutional behavior.  相似文献

Solutions to Army personnel problems are of critical importance. Personnel issues continue to be problematic in a number of areas including: recruit intelligence level, careerist motivation of recruits, and the maintenance of trained, quality careerists in the all volunteer force (AVF). High attrition of skilled personnel is not related only to pay scale; pride in service, as well as intrinsic rewards may also relate to the retention and attraction of career‐motivated soldiers. This study analyzed the inducements offered and demands made of potential volunteers in brochures advertising the AVF. Most of the appeals in such brochures focused on instrumental rewards available to potential recruits, while few appeals featured traditional intrinsic satisfactions of military service as a motive for joining the AVF. The advertising strategy presently used in AVF brochures may explain in part why poor retention of skilled careerists continues to be one of its most severe problems. Recommendations for structuring future appeals are offered based on the findings.  相似文献

Clutch performance is improved performance under pressure. However, little research has examined the psychological state experienced by athletes in these situations. Therefore, this study qualitatively examined the subjective experience underlying clutch performance across a range of sports (e.g., team, individual) and standards (Olympic to recreational athletes). Sixteen athletes (Mage = 27.08 years; SD = 6.48) took part in in-depth, semi-structured interviews primarily after an exceptional performance (M = 4.38 days later; SD = 3.14). Data were analysed inductively and thematically. Clutch states involved 12 characteristics, including heightened and deliberate concentration, intense effort, and heightened awareness, which distinguished the experience of clutch from other optimal psychological states such as flow. Other characteristics, such as perceptions of control, were also reported and supported previous experimental research on clutch. These findings present in-depth qualitative insights into the psychological state underlying clutch performance, and are discussed in relation to the existing literature on optimal psychological states in sport.  相似文献
