ABSTRACT The present study aimed to provide reference values for lower-limb muscle power assessed during the incremental jump squat (JS) test in elite athletes (i.e., professional athletes competing at international level). We pooled data from all JS tests performed by elite athletes of different sports in two high-performance centres between 2015 and 2019, and computed reference values (i.e., terciles) for mean power (MP), mean propulsive power (MPP), and peak power (PP). Reference values were obtained from 684 elite athletes (458 male and 226 female) of 16 different sports (boxing, judo, karate, fencing, taekwondo, wrestling, basketball, soccer, futsal, handball, rugby union, badminton, tennis, long distance running, triathlon, and sprinting). Significant differences (p < 0.001) were found between male and female athletes for MP (7.47 ± 1.93 and 6.15 ± 1.68 W·Kg?1, respectively), MPP (10.50 ± 2.75 and 8.63 ± 2.43 W·Kg?1), and PP (23.64 ± 6.12 and 19.35 ± 5.49 W·Kg?1). However, the velocity at which these power measures was attained seemed to be independent of sex (~0.95, 1.00 and 2.00 m·s?1 for mean, mean propulsive, and peak velocity, respectively) and homogeneous across different sport disciplines (coefficient of variation <10%). These data can be used to classify athletes’ power capabilities, and the optimum velocity ranges provided here could be useful for training purposes. 相似文献

This study seeks to develop and validate an Assessment Centre (AC) tool for the evaluation and selection of school leaders, focusing on the identification of competencies that influence teaching and learning outcomes. International research supports the creation of Assessment Centres to select candidates for these roles, due to their superior predictive capacity over traditional methods. In this research, a model composed of four face-to-face instruments (an interview to assess competencies, a human resources exercise, a class observation exercise, and a strategic analysis exercise) was designed and validated which simulated the key tasks of a school principal. To establish the desired performance outcomes, three competencies and 15 indicators were selected, based on international and local standards. The analysis of performance results was obtained from a sample of 164 participants made up of teachers, school leaders and principals. The results suggest positive evidence for construct validity, concurrent criteria validity, and reliability between evaluators. Moreover, the data obtained from a sub-sample of principals, with three or more years of experience in their role, allowed for the association of their AC scores with the results of their school organisations, as measured by the National System for the Measurement of Educational Quality in the years 2013 and 2016. 相似文献

In this paper we use data from household surveys of 12 Latin American countries to assess how teacher salaries compare to workers in other occupations. The results show great variability from one country to another, ranging from an apparent underpayment of teachers in Bolivia by 35% relative to the control group, and a respective overpayment of 65% in Colombia. However, when statistical controls are introduced for the differential education, hours worked and gender composition between teachers and the comparison group, much of the earnings differential between the two groups disappears. On the basis of this finding, we cannot support the position that teachers are either overpaid or underpaid. 相似文献

This paper is based on a multiple case study of schools which have been identified as improving their performance for about a decade. We proposed different criteria by which to characterize and study these improvement processes and, by applying them to our sample, we elaborated a typology of school improvement trajectories: we identified 4 different trajectories of school improvement. We called the first type restricted improvement because at its center is the management of processes that mainly target academic achievement tests; the second is incipient improvement, which is based on changes that restructure the school processes; the third identified trajectory are cases where school improvement is moving toward institutionalization, while the last are those cases where improvement has been already institutionalized and the schools have achieved high levels of educational effectiveness. We identified challenges that schools face at different stages of school improvement and discussed some related policy issues. 相似文献

In recent decades, higher education institutions worldwide have been moving from knowledge-based to competence-based curricula. One of the greatest challenges in this transition is the difficulty in changing the knowledge-oriented practices of teachers. This study evaluates the consistency between syllabus design and the requirements imposed by a competence-based learning environment. To make this comparison, the study sets four criteria (C1: explicit relationship between syllabus and graduate profile; C2: precision of the learning outcomes and assessment criteria; C3: contents that mobilise the learning outcomes; and C4: learning and assessment activities) derived from the literature and a thematic analysis of competence-based learning in higher education. Afterwards, a sample of 150 syllabi from different disciplines of five Chilean public universities were analysed, all of which stated the use of learning outcomes and competences in their learning models. Using a three-point Likert scale derived from the aforementioned criteria and their indicators, a comparison was made between the actual practices reflected in the syllabus design and the previously established criteria. Results show a gap between the declaration of a competency-based curriculum and actual syllabus outlines. Moreover, there are important differences among disciplines. Although all disciplines present high levels of accomplishment for Criteria 1 and 3, only the discipline of health sciences presents an acceptable level for Criteria 2 and 4. It is recommended that further research be undertaken towards identifying effective competency-based syllabus design. 相似文献
