AbstractThis study analysed the effect of imposing a pause between the eccentric and concentric phases on the biological within-subject variation of velocity- and power–load isoinertial assessments. Seventeen resistance-trained athletes undertook a progressive loading test in the bench press (BP) and squat (SQ) exercises. Two trials at each load up to the one-repetition maximum (1RM) were performed using 2 techniques executed in random order: with (stop) and without (standard) a 2-s pause between the eccentric and concentric phases of each repetition. The stop technique resulted in a significantly lower coefficient of variation for the whole load–velocity relationship compared to the standard one, in both BP (2.9% vs. 4.1%; P = 0.02) and SQ (2.9% vs. 3.9%; P = 0.01). Test–retest intraclass correlation coefficients (ICCs) were r = 0.61–0.98 for the standard and r = 0.76–0.98 for the stop technique. Bland–Altman analysis showed that the error associated with the standard technique was 37.9% (BP) and 57.5% higher (SQ) than that associated with the stop technique. The biological within-subject variation is significantly reduced when a pause is imposed between the eccentric and concentric phases. Other relevant variables associated to the load–velocity and load–power relationships such as the contribution of the propulsive phase and the load that maximises power output remained basically unchanged. 相似文献

Peer assessment (PA) is one of the central principles of formative assessment and assessment for learning (AfL) fields. There is ample empirical evidence as to the benefits for students’ learning when AfL principles are implemented. However, teachers play a critical role in mediating the implementation of intended policies. Hence, their experiences, beliefs, and attitudes towards PA are important factors in determining whether the policy is actually carried out. A survey of over 1500 primary, secondary, and higher education teachers in Spain elicited their beliefs and values around PA as well as other aspects of formative assessment; only 751 teachers provided complete responses to all PA items. Teachers reported occasional use of PA in their classrooms but with positive experience of it. The vast majority did not use anonymous forms of PA and half of the teachers considered the students were accurate when assessing peers. Confirmatory factor analysis and structural equation modeling were used to examine relationships of attitudes and beliefs to self-reported frequency of using of PA. The self-reported frequency of using PA was strongly predicted by teacher experience of PA which included positive reasons for using PA, rather than negative obstacles for avoiding, prior use, and beliefs that students should participate in assessment, and willingness to include PA in grading. 相似文献

Evaluative judgement is the capability to make decisions about the quality of work of oneself and others. In this paper, we propose that developing students’ evaluative judgement should be a goal of higher education, to enable students to improve their work and to meet their future learning needs: a necessary capability of graduates. We explore evaluative judgement within a discourse of pedagogy rather than primarily within an assessment discourse, as a way of encompassing and integrating a range of pedagogical practices. We trace the origins and development of the term ‘evaluative judgement’ to form a concise definition then recommend refinements to existing higher education practices of self-assessment, peer assessment, feedback, rubrics, and use of exemplars to contribute to the development of evaluative judgement. Considering pedagogical practices in light of evaluative judgement may lead to fruitful methods of engendering the skills learners require both within and beyond higher education settings. 相似文献

Peers carry potential in enhancing students’ self-assessment development, but few studies have explored how peer scaffolding is enacted in the process. This qualitative study explores peer assessment effects on the self-assessment process of 11 first-year undergraduates and the factors limiting peer influence. Drawing on the data from students’ journals, follow-up interviews, observations of in-class formative peer assessment activities and teacher interviews, we ascertained that peers could aid the self-assessment process by enriching student understanding of quality, refining subjective judgement and deepening self-reflection. Yet, peer influence could be reduced by distrust, tensions in feedback communication, competition and lack of readiness for peer learning. Implications for effective use of peers in supporting self-assessment development are discussed. 相似文献

The purpose of this study was to evaluate the teaching effectiveness of the Trimodal Programmed Instruction in Reading with those inefficient learners who were making limited or no progress in their elementary school reading programs despite other remedial procedures. Based on their performance on a criterion pretest, nine second, third, and fouth graders were assigned to either a full remedial program, consisting of 25 lessons or to a partial program consisting of between 14 and 17 programs. Each child interacted at the Teledesk (the main piece of equipment) on a daily basis, for approximately 15 minutes; one program per day was permitted. The Trimodal Reading Instruction approach employs a programmed technique using the whole word method of reading instruction. Word recognition and comprehension skills are fostered by having the pupil actively construct sentences by placing plaques associated with whole words on an interface. A policy of limited supervision and limited directive guidance was employed. Results indicated that subjects in both full and partial programs dramatically improved on word recognition and comprehension tasks, when post‐tested. 相似文献

PurposeThe aim of the present study was to assess both the credibility and strength of evidence arising from systematic reviews with meta-analyses of observational studies on handgrip strength and health outcomes.MethodsAn umbrella review of systematic reviews with meta-analyses of observational studies was conducted. We assessed meta-analyses of observational studies based on random-effect summary effect sizes and their p values, 95% prediction intervals, heterogeneity, small-study effects, and excess significance. We graded the evidence from convincing (Class I) to weak (Class IV).ResultsFrom 504 articles returned in a search of the literature, 8 systematic reviews were included in our review, with a total of 11 outcomes. Overall, nine of the 11 of the outcomes reported nominally significant summary results (p < 0.05), with 4 associations surviving the application of the more stringent p value (p < 10−6). No outcome presented convincing evidence. Three associations showed Class II evidence (i.e., highly suggestive): (1) higher handgrip values at baseline were associated with a minor reduction in mortality risk in the general population (n = 34 studies; sample size = 1,855,817; relative risk = 0.72, 95% confidence interval (95%CI): 0.67–0.78), (2) cardiovascular death risk in mixed populations (n = 15 studies; relative risk = 0.84, 95%CI: 0.78–0.91), and (3) incidence of disability (n = 7 studies; relative risk = 0.76, 95%CI: 0.66–0.87).ConclusionThe present results show that handgrip strength is a useful indicator for general health status and specifically for early all-cause and cardiovascular mortality, as well as disability. To further inform intervention strategies, future research is now required to fully understand mechanisms linking handgrip strength scores to these health outcomes. 相似文献
