In this article we explore the level of job satisfaction and the sources of job dissatisfaction for 210 secondary school teachers in southwest England and compare our results with the results from a similar study published in 1962. Using anonymous questionnaires, we asked 210 secondary teachers in southwest England (63% female) to rate their level of job satisfaction and to rate 16 sources of job dissatisfaction that we adapted from the 1962 study. Teachers in 2007 rated their job satisfaction significantly lower and ordered the sources of job dissatisfaction significantly differently than did teachers in 1962. Whereas teachers in 1962 were most concerned with external sources of job dissatisfaction (e.g. salary, condition of buildings and equipment and poor human relations), teachers in 2007 expressed the most concern about factors relating to teaching itself (e.g. time demands and pupils' behaviour). The changes in sources of dissatisfaction hold true for male and female teachers, with no difference in rankings according to years of teaching experience.  相似文献

Almost 12 years since the publishing of Terminologia Anatomica (TA) by the Federative Committee on Anatomical Terminology (FCAT), there has yet to be a unified adoption of FCAT‐recommended anatomical terms by North American anatomists. A survey was sent to members of the Human Anatomy & Physiology Society (HAPS) to compare the frequency of FCAT term usage with a previous study involving the American Association of Anatomists (AAA). The HAPS differed from AAA in being composed mostly of biologists (56.5%) who teach anatomy with only 18.3% of respondents having terminal degrees in anatomy. The survey included the same 25 sets of synonymic names for selected gross anatomical structures or related terms used for the AAA survey. Overall results indicate that the FCAT preferred term had the highest frequency of usage in only 40.0% of the survey questions, demonstrating 4% lower compliance than AAA respondents. Compliance with FCAT preferred terms ranged from 92.2% to 1.7% usage. When compared with AAA anatomists, there were reversals in predominant usage between FCAT and non‐FCAT terms for six sets of anatomical structures: HAPS respondents predominantly used non‐FCAT terms for adrenal gland (88.7%), antecubital fossa (57.4%), patellar tendon (65.2%), ligamentum capitis femoris (36.5%), while preferring the FCAT anterior circumflex humeral artery (45.2%) and anterior/posterior preferred over ventral/dorsal (41.7%). Almost 54% of HAPS anatomists were not familiar with the FCAT, nearly 21% higher than the AAA. Anat Sci Educ 3:25–32, 2010. © 2009 American Association of Anatomists.  相似文献

Evidence-based policies, decisions, and practices are highly valued and underachieved in the international mathematics and science education reforms. Many in the mathematics and science education research communities lament the lack of influence that research results have on the education profession, schools, and teaching. Academic research done in isolation of end-users—with the faint hope that teachers, politicians, and bureaucrats will access and utilise these results to inform curriculum, assessment, and instruction and to influence public policy—has not worked. Some funding agencies require dissemination of research and development results to the broader political and education communities; therefore, applicants agree to these requirements without fully realizing the breadth of these demands. However, to achieve such knowledge transfer requirements, researchers need to become more (a) aware of the needs, players, and processes of ‘speaking truth to power’; (b) active in knowledge transfer and influencing public policy; and (c) alert to values and normative premises of the policy makers. This article outlines the essential principles, barriers within the academic community, international efforts, and future considerations for knowledge transfer regarding international assessments. Specific articles on PISA 2000, 2003, and 2006 included in this special issue are used to illustrate these insights into verification of curricular influences, educational opportunity and equality, regional comparisons, and direct influence on policy.  相似文献

A meta‐analysis was conducted with 65 school‐based psychotherapy and counseling dissertations over the last 10 years (1998–2008) to assess if a file‐drawer problem (i.e., studies conducted but not published that, as a whole, have different results than studies in the same area published) exists in the school‐based outcome literature. An overall mean effect size of 0.44 was found for 73 treatment interventions. This effect size is comparable to Prout and DeMartino's 1986 meta‐analysis conducted with published school‐based studies and approximately half a standard deviation smaller than Prout and Prout's 1998 meta‐analysis of school‐based intervention studies. A bias does appear to exist but seems to be smaller than the bias found in the general child and adolescent psychotherapy outcome literature. Most of the dissertation studies evaluated group interventions and used a cognitive–behavioral or skills training intervention. Skills training and interventions with elementary‐school students yielded the largest effect sizes. Comparisons of the current study with previous school‐based intervention meta‐analyses are discussed as are suggestions for future research. © 2010 Wiley Periodicals, Inc.  相似文献

This study investigated the associations between fundamental athletic movement and physical fitness in junior Australian football (AF). Forty-four under 18 players performed a fundamental athletic movement assessment consisting of an overhead squat, double lunge, single leg Romanian deadlift and a push up. Movements were scored on three assessment criterions using a three-point scale. Additionally, participants performed five physical fitness tests commonly used for talent identification in AF. A Spearman’s nonparametric correlation matrix was built, with correlation coefficients being visualised using a circularly rendered correlogram. Score on the overhead squat was moderately positively associated with dynamic vertical jump height on left (rs = 0.40; P ≤ 0.05) and right (rs = 0.30; P ≤ 0.05) leg take-off, stationary vertical jump (rs = 0.32; P ≤ 0.05) and negatively associated with 20-m sprint time (rs = ?0.35; P ≤ 0.05). Score on the double lunge (left/right side) was moderately positively associated with the same physical fitness tests as well as score on the multistage fitness test. Results suggest that improvements in physical fitness qualities may occur through concurrent increases in fundamental athletic movement skill, namely the overhead squat and double lunge movements. These findings may assist with the identification and development of talent.  相似文献

Abstract

Best practice for improving strength and power through resistance strength training has been the subject of much research and subsequent conjecture. Much of the conjecture can be attributed to methodological discrepancies. The type of dynamometry used in testing, the training experience of research participants, the specific technique employed in a lift, and the methods of collection and calculation all impact on the final variables of interest. This review examines contraction force specificity by first addressing the methodological issues surrounding our interpretation of the results. Then we address the kinematics and kinetics associated with single and multiple repetitions in relation to the development of strength, power, and functional performance. This discussion provides the delimitations for analysis of subsequent training studies. Finally, recommendations are formulated with the aim of assisting assessment and training practice as well as providing directions for future research. The results of this review suggest that the enhancements in performance resulting from resistance training are context specific in experienced resistance-trained participants. Thus, specific conditioning could be required to achieve improvements in functional performance in this group.  相似文献

ABSTRACT

Objective: To explore whether basketball player’s self-determined motivation interacts with environmental contexts and coach training to influence percentage time in moderate-to-vigorous physical activity (%MVPA). Methods: A secondary analysis of data from 76 girls (mean ± SD, 10.5 ± 1.0 years) was conducted. Players were classified as high self-determined motivation (HSDM) or low self-determined motivation (LSDM) and randomised to trained (intervention) or untrained (control) coaches. Training included 2 workshops on strategies for activity-promoting practices. Girls were exposed to environmental contexts (practices and games) led by a trained/untrained coach (depending on arm) and one without coaches (free time) daily. Girls wore accelerometers each day. Using mixed random-effects models, the influence of motivation, context and training on %MVPA was analysed. Results: Trained coaches’ practices were associated with the greatest %MVPA with no difference between HSDM and LSDM players (38.28 ± 1.77%; 37.64 ± 1.80%; p = 0.66). HSDM players had significantly greater %MVPA versus LSDM players during untrained coaches’ practices (23.58 ± 1.77%; 20.51 ± 1.78%; p = 0.03). During games with trained coaches, HSDM players had greater %MVPA compared to LSDM players (23.79 ± 1.76%; 18.56 ± 1.74%; p < 0.001). No between-group difference in %MVPA during free time was found (12.85 ± 0.82%; 13.39 ± 0.84%; p = 0.64). Conclusion: The impact of individual differences in self-determined motivation on %MVPA during practices was attenuated when coaches were trained to implement activity-promoting practices.  相似文献
