A 20-week classroom-based study was conducted to investigate the extent to which a computerized learning environment could facilitate students' development of higher-level thinking skills associated with scientific inquiry. In two classes students' interactions with a scientific data base—Birds of Antarctica—were closely monitored, and the mediating roles of the teachers' epistemologies were examined. Interpretive data were generated and analyzed in relation to a constructivist perspective on learning. In the class where the teacher implemented a constructivist-oriented pedagogy, students took advantage of enhanced opportunities to generate creative questions and conduct complex scientific investigations. These higher-level thinking skills were much less evident in the class in which a more transmissionist-oriented pedagogy prevailed. The results of the study suggest that it is not the computer itself that facilitates inquiry learning; the teacher's epistemology is a key mediating influence on students' use of the computer as a tool of scientific inquiry. 相似文献

Whereas a lot of studies examine cognitive processes in chess players, personality profiles of elite chess players are still not described well. The aim of this study was to examine personality of strong chess experts and its influence on chess skill. We tested elite male and female chess players with Freiburg Personality Inventory Revised (FPI-R), which also provides population norms for males and females. Elite male players' personality profile did not significantly differ from the population norms. Female players were more satisfied with life, had less physical complaints and higher achievement motivation in comparison with female population norms. Personality was also related with chess skill but showed different patterns in males and females. Stronger male players were more introverted, while we found the opposite pattern in female players. These results indicate that personality plays an important role in the highest level of complex intellectual activities. 相似文献

Play in the Preschool Classroom: Its Socioemotional Significance and the Teacher’s Role in Play 总被引:2,自引:0,他引:2
Godwin S. Ashiabi 《Early Childhood Education Journal》2007,35(2):199-207
The goals of this paper were two-fold. The first goal was to examine the emotional and social developmental value of play
in the early childhood classroom. This issue is important because of the recent impetus for a more academic focus in early
childhood classrooms, and questions about the developmental benefits of play. The second goal was to examine and discuss the
role teachers could play in making play a developmental and educational experience. This is because understanding the significance
of play could make teachers less apprehensive about using play to promote learning and development, and enable them answer
questions regarding the value of play. Using these goals as a backdrop, this paper discussed views of children’s play; the
defining characteristics of emotional and social development; play and the socioemotional development of children; and the
role of early childhood teachers in children’s play. 相似文献

Three hundred and sixty-seven secondary school students across five year levels (8–12) were assessed for levels of career maturity (attitude and knowledge), work commitment, work value, career decidedness (indecision and certainty), career decision-making self-efficacy and self-esteem, and indicated their age, gender, socioeconomic status, school achievement and work experience. Using two multiple regression analyses, the predictor variables were able to account for 52% of the variance of career maturity attitude, and account for 41% of the variance of career maturity knowledge. Self-efficacy, age, career decidedness (certainty) and work commitment were the main predictors of career maturity attitude. Age, gender, career decidedness (certainty), work commitment and career decidedness (indecision) were the main predictors of career maturity knowledge. Results demonstrated the importance of examining two aspects of career maturity (attitude and knowledge), and were discussed in the context of Super's (1957, 1990) theory of career development. 相似文献

The aim of the present study was to examine the factorial validity of the Test of Performance Strategies (TOPS; Thomas et al., ) among adolescent athletes using confirmatory factor analysis. The TOPS was designed to assess eight psychological strategies used in competition (i.e. activation, automaticity, emotional control, goal-setting, imagery, negative thinking, relaxation and self-talk,) and eight used in practice (the same strategies except negative thinking is replaced by attentional control). National-level athletes (n?=?584) completed the 64-item TOPS during training camps. Fit indices provided partial support for the overall measurement model for the competition items (robust comparative fit index?=?0.92, Tucker-Lewis index?=?0.88, root mean square error of approximation?=?0.05) but minimal support for the training items (robust comparative fit index?=?0.86, Tucker-Lewis index?=?0.81, root mean square error of approximation?=?0.06). For the competition items, the automaticity, goal-setting, relaxation and self-talk scales showed good fit, whereas the activation, emotional control, imagery and negative thinking scales did not. For the practice items, the attentional control, emotional control, goal-setting, imagery and self-talk scales showed good fit, whereas the activation, automaticity and relaxation scales did not. Overall, it appears that the factorial validity of the TOPS for use with adolescents is questionable at present and further development is required. 相似文献

The primary roles for nutrition in sprints are for recovery from training and competition and influencing training adaptations. Sprint success is determined largely by the power-to-mass ratio, so sprinters aim to increase muscle mass and power. However, extra mass that does not increase power may be detrimental. Energy and protein intake are important for increasing muscle mass. If energy balance is maintained, increased mass and strength are possible on a wide range of protein intakes, so energy intake is crucial. Most sprinters likely consume ample protein. The quantity of energy and protein intake necessary for optimal training adaptations depends on the individual athlete and training demands; specific recommendations for all sprinters are, at best, useless, and are potentially harmful. However, if carbohydrate and fat intake are sufficient to maintain energy levels, then increased protein intake is unlikely to be detrimental. The type and timing of protein intake and nutrients ingested concurrently must be considered when designing optimal nutritional strategies for increasing muscle mass and power. On race day, athletes should avoid foods that result in gastrointestinal discomfort, dehydration or sluggishness. Several supplements potentially influence sprint training or performance. Beta-alanine and bicarbonate may be useful as buffering agents in longer sprints. Creatine may be efficacious for increasing muscle mass and strength and perhaps increasing intensity of repeat sprint performance during training. 相似文献

The increased emphasis on school‐based programmes as part of initial teacher education has resulted in renewed efforts to forge more effective partnerships between higher education institutions and schools. The University of Bath has established a mentor development programme to ensure that subject mentors have an opportunity to examine ways to engage novice teachers in critical reflection about their practice while providing the support and challenge necessary to help them develop as teachers. This study is based on experienced mentors’ and their perspective on their work with novice teachers and it is a follow‐up to earlier research based on Daloz’ model (1986, Effective Teaching and Mentoring, San Francisco, Jossey Bass) of support and challenge. It examines an emerging mentoring pedagogy through which experienced mentors attempt to engage novice teachers in shaping their own vision of teaching. Three mentor profiles are discussed—the laissez‐faire, the collaborative and the imperial mentor. 相似文献
