The impact of perceived wellness on a range of external load parameters, rating of perceived exertion (RPE) and external load:RPE ratios, was explored during skill-based training in Australian footballers. Fifteen training sessions involving 36 participants were analysed. Each morning before any physical training, players completed a customised perceived wellness questionnaire (sleep quality, fatigue, stress, mood and muscle soreness). Microtechnology devices provided external load (average speed, high-speed running distance, player load and player load slow). Players provided RPE using the modified Borg category-ratio 10 RPE scale. Mixed-effect linear models revealed significant effects of wellness Z-score on player load and player load slow. Effects are reported with 95% confidence limits. A wellness Z-score of ?1 corresponded to a ?4.9 ± 3.1 and ?8.6 ± 3.9% reduction in player load and player load slow, respectively, compared to those without reduced wellness. Small significant effects were also seen in the average speed:RPE and player load slow:RPE models. A wellness Z-score of ?1 corresponded to a 0.43 ± 0.38 m·min?1 and ?0.02 ± 0.01 au·min?1 change in the average speed:RPE and player load slow:RPE ratios, respectively. Magnitude-based analysis revealed that the practical size of the effect of a pre-training perceived wellness Z-score of ?1 would have on player load slow was likely negative. The results of this study suggests that monitoring pre-training perceived wellness may provide coaches with information about the intensity of output that can be expected from individual players during a training session. 相似文献

This paper describes a research project into undergraduates’ use of a software tool to learn symbolic logic—a complex abstract domain that has been shown to be intimidating for students. The software allows the students to manipulate proofs in certain ways and then calculates the consequences of their actions. A research method has been developed that allowed students’ use of this tool to be modelled, and this model was then used to identify, refine and create visual cues that provide support for students’ reasoning. The focus of this paper is the role of the software as an artefact to aid students’ visualisation of reasoning processes rather than the logic itself. The main mechanisms by which this visualisation is supported are the imposition of constraints on the actions available and the demonstration to students of the consequences of their actions. The study shows that the software encouraged experimentation with different routes to a proof, and constituted a challenge to fixated reasoning. 相似文献

ABSTRACT Ensuring that students of all backgrounds are smoothly transitioned through the stages of access, participation and completion in higher education has been the focus of much public policy and research in recent decades. Subsequently, public policy discourse treats those who do not complete their higher education degrees as unsuccessful, despite a lack of research considering the beneficial outcomes of non-completing students. Evidence of beneficial outcomes of higher education participation without completion has potential to challenge the deficit-centric discourse of completion dependent on a binary view of success and failure. This article details a critical discourse analysis of responses to a 2017 survey of university non-completers asked ‘were there any benefits from the time you spent doing an [sic] incomplete degree?’. This study finds that non-completers experience a wide range of benefits from incomplete studies despite the dominant discourse discounting their experiences as unsuccessful. Additionally, this study presents a critique of framing surveys of non-completing students within the normative bounds of success as completion in higher education, and instead calls for a more nuanced construction of success in higher education. 相似文献

This paper describes the principled design of a computational environment which depicts an animated story of the execution of programs for novice programmers. The design principles are aimed at solving the problems that novice programmers face when learning new programming languages, and are embodied in an Animated Program Tracer (APT) for Prolog. The goal of this research is to develop a more systematic, if not yet scientific, basis for the design of animated tracing tools. 相似文献

The school system in England is undergoing rapid change, with the government creating more than 4000 ‘independent publicly funded schools’, known as academies, since 2010. The potential for fragmentation is considerable with diversity of governance emerging as a key feature of the new schooling landscape. Consequently, a major and widely recognised issue to which these reforms give rise concerns the future of the ‘middle tier’ –that layer between individual schools or groups of schools and central government. There are competing visions of how a future middle tier might evolve: one focuses entirely on a middle tier of individual schools and chains as a ‘self-improving system’; others conceive a continuing but revised role for the local authority (LA). The aim of this paper is to begin to explore the latter position, and in particular the potential role of the LA as a ‘broker’ of new patterns of school organisation. Drawing on interview data from three very different LA areas, the findings show that LAs differ in how they conceive their role and, consequently, on the strategies that they pursue. 相似文献
