We undertook two studies to determine the validity and reliability of the revised Perceived Motivational Climate in Sport Questionnaire (PMCSQ-2). In Study 1, 201 female athletes (mean age 16.4 years) were administered the initial version of the PMCSQ-2 and a measure of reported tension and pressure experienced in sport. Exploratory principal component analysis suggested that the PMCSQ-2 contained two higher-order scales (Task-Involving and Ego-Involving climates), each with three subscales (Task: Cooperative Learning, Effort/Improvement, Important Role; Ego: Intra-Team Member Rivalry, Unequal Recognition, Punishment for Mistakes). In Study 2, 385 female volleyball players (mean age 15.2 years) completed the PMCSQ-2, the Intrinsic Motivation Inventory and a measure of Team Satisfaction. Confirmatory factor analysis was applied to six competing models. The oblique six-factor model and oblique hierarchical model provided comparable fit to the data. Acceptable fit was reached based on model respecification. Across Studies 1 and 2, internal consistency was found to be acceptable for the higher-order scales and subscales (with the exception of the Intra-Team Member Rivalry subscale). We found evidence for the concurrent validity of the instrument.  相似文献

The aim of this study was to investigate the effects of target distance on temporal and impact force parameters that are important performance factors in taekwondo kicks. Forty-nine taekwondo athletes (age = 24.5 ± 5.9 years; mass = 79.9 ± 10.8 kg) were recruited: 13 male experts, 21 male novices, 8 female experts, and 6 female novices. Impact force, reaction time, and execution time were computed. Three-way repeated measure ANOVAs revealed significant ‘distance’ effect on impact force, reaction time, and execution time (p = 0.001). Comparisons between distance conditions revealed that taekwondo athletes kicked with higher impact force from short distance (17.6 ± 7.5 N/kg) than from long distance (13.1 ± 5.7 N/kg) (p < 0.001), had lower reaction time from short distance (498 ± 90 ms) and normal distance (521 ± 111 ms) than from long distance (602 ± 121 ms) (p < 0.001), and had lower execution time from short distance (261 ± 69 ms/m) than from normal distance (306 ± 105 ms/m) or from long distance (350 ± 106 ms/m) (p = 0.003 and p < 0.001, respectively). In conclusion, target distance affected the kick performance; as distance increases, impact force decreased and reaction time increased. Therefore, when reaction to a simple visual stimulus is needed, kicking from a long distance is not recommended, as longer time is required to respond.  相似文献

Trainee teachers, new and non-specialist teachers of elementary mathematics have a tendency to avoid thought about reasons in mathematics. Instead, they tend to favour the development of computational skill through the rote application of procedures, routines and algorithms. Could elementary mathematics textbooks serve as models of practice and support the professional development of these teachers? Eighteen such textbooks for use by 7 to 11-year-old children in England were examined for their potential to help teachers attend to reasons. It was found that they were unlikely to point teachers towards reasons for patterns and procedures. Although some had the potential to help in introducing and structuring a lesson, they were unlikely to induce the teacher to address matters of understanding in their discourse. Their implicit message tended to be that mathematics education is about computational skill development through routines, algorithms and practice.  相似文献

Support is needed to promote problem-based learning (PBL) and to enhance critical thinking skills in discussion-based Internet forums. By advancing the capabilities of chat room and forum software, problem-based discussions for learning can be supported further in online learning environments. In this paper, the authors report on MALESAbrain, an intelligent learning tool. The model is built on the notions of threshold and knowledge weight from the discipline of machine learning. The model encourages learners to judge or critically evaluate the solutions posted by others before exploring further knowledge content. The system then sums up the judgment scores as its knowledge weight to pass the thresholds setup for ranking/arranging the learning issues. This constraint design, therefore, becomes a mechanism for critical thinking in a problem-based learning activity. MALESAbrain as a model helps transform the forum and chat room into rich learning discussion environments.  相似文献

Widely thought to be something worth encouraging in young learners, creativity has popularly been associated more with music and art than with other areas of the curriculum. There have been many studies of creativity but few that focus explicitly on what counts as creative thinking in specific subject areas. The aim of the research reported here was to determine pre-service teachers’ conceptions of creativity within the curriculum for English. The study involved analyses of primary school trainee teachers’ responses to questionnaires and follow-up focus group discussion to identify their conceptions. A group of 48 trainees in the final year of an undergraduate degree in primary education leading to qualified teacher status in England completed the questionnaire. Of these, eight volunteered to participate in a follow-up focus group discussion to further explore ideas. Responses were analysed quantitatively and qualitatively. Conceptions of creativity in English were found to be limited, focused mainly on naïve views of story writing and dramatic activity. Responses indicated that they were often unable to distinguish clearly between the concept of creativity, an example of its occurrence in the classroom, and what feature of that example made it creative. Consequently, their limited constructions of creativity were confused. It is important that teachers in schools as well as those responsible for training teachers in universities are advised that trainees’ conceptions of creativity in English may be inadequate in several respects and that they may not recognise opportunities for creativity. Pre-service training programmes could well benefit from structured courses on the forms and applications of creativity.  相似文献

This study examines use of the card catalogue by staff and undergraduate and postgraduate students of Ladoke Akintola University of Technology, Ogbomoso, Oyo state, Nigeria. The population sample was comprised of 1,200 library users randomly selected from 13,592 registered library users at the Ladoke Akintola University of Technology, Ogbomoso. Results from questionnaires established that the library card catalogue was underutilized by the undergraduate students (44%), but more heavily used by postgraduate students (78%), academic staff (74%), and administrative staff (66%). Recommendations are suggested to improve catalogue use in the library.  相似文献

Few studies have empirically investigated the specific factors in mentoring relationships between undergraduate researchers (mentees) and their mentors in the biological and life sciences that account for mentees’ positive academic and career outcomes. Using archival evaluation data from more than 400 mentees gathered over a multi-year period (2005–2011) from several undergraduate biology research programs at a large, Midwestern research university, we validated existing evaluation measures of the mentored research experience and the mentor–mentee relationship. We used a subset of data from mentees (77% underrepresented racial/ethnic minorities) to test a hypothesized social cognitive career theory model of associations between mentees’ academic outcomes and perceptions of their research mentoring relationships. Results from path analysis indicate that perceived mentor effectiveness indirectly predicted post-baccalaureate outcomes via research self-efficacy beliefs. Findings are discussed with implications for developing new and refining existing tools to measure this impact, programmatic interventions to increase the success of culturally diverse research mentees and future directions for research.  相似文献

(The Revised Standard Version of the Bible is ten years old. During this period it has been tested in every conceivable way: by the scholars, by use in all kinds of worship, by classes in church‐related educational programs, by students in colleges and theological schools. It has proven itself a valid translation and a means of proclaiming the revelation of God in Jesus Christ. It has had widespread use in Roman Catholic colleges. It is now appearing in many new editions as other publishers are being licensed to print it. To Luther A. Weigle and his teams of devoted translators we give our grateful thanks. ‐‐ Ed.)  相似文献
