ABSTRACT The aim of this pilot study was to evaluate the impact of a novel coach development intervention (MASTER) on coaching practices of football coaches. The study involved six coaches (of 10–12 year old) from one representative football club (Australia February–July 2017). The 15-week multi-component intervention included a face-to-face workshop, ongoing mentoring, modelled training sessions, peer assessments and group discussions. MASTER is underpinned by positive coaching and game-based coaching practices and aimed to educate coaches on how to implement and operationalise a number of evidence-based coaching elements. At each of baseline and immediate post-intervention coaches were filmed three times and evaluated using a modified version of the Coach Analysis Intervention System. Using linear mixed model analysis, significant changes were observed for time spent performing playing-form activities [+15.4% (95% CI 6.01–24.79)(t(15) = 3.5, P = 0.003], with significant changes in the type of interventions undertaken and the nature of feedback given to athletes. Program feasibility was examined using measures of recruitment, retention, adherence and satisfaction. Results indicate program feasibility and high coach evaluation ratings. MASTER demonstrated effectiveness for improving coaching practices of football coaches during training sessions. Further large-scale trials will build evidence for the utility of MASTER for guiding coaching practices in football and other sporting codes. 相似文献

Three conditioned suppression experiments with rats as subjects investigated the influence of higher order associations in determining the response potential of a target stimulus. In these experiments, a Pavlovian conditioned inhibitor was compounded with the target cue during extinction treatment. In Experiment 1, strong suppression was observed to the target cue that was given extinction treatment in the presence of a conditioned inhibitor, relative to a target that was extinguished with an associatively neutral cue or was extinguished alone, suggestive of enhanced protection from extinction provided by a conditioned inhibitor. This effect was replicated in a sensory preconditioning preparation in Experiment 2; in Experiment 3, in a sensory preconditioning preparation, this protection effect was retroactively attenuated when the conditioned excitor used to train the conditioned inhibitor was extinguished following extinction of the target. This provides evidence that, at least in a sensory preconditioning preparation, stimuli that are only indirectly associated with the target cue can contribute to the response potential of that target. 相似文献

The aim of the study was to elucidate the nature and efficiency of the strategies that readers with phonological dyslexia
use for temporary retention of written words in Working Memory (WM). Data was gathered through a paradigm whereby participants
had to identify serially presented written (target) words from within larger word pools according to their presentation order,
with word pools containing code-specific distracter (CSD) words and non-code-specific distracter (NCSD) words. Analyses focused
on three aspects of performance: (1) false recognition of target words; (2) correct recognition of target words; and (3) retention
of word presentation order. Participants were readers with diagnosed phonological dyslexia (n = 20, mean grade level = 9.05 [0.89]) and a control group of regular readers (n = 25, mean grade level = 9.00 [0.76]). Results provide direct evidence that the dyslexic readers and the regular readers
used essentially different memory coding strategies for the temporary retention of written words, with the former predominantly
relying on a visual strategy and the latter on a phonological strategy. Findings further pinpointed a notably impoverished
ability of the dyslexic readers to retain word presentation order. The implication of these findings is discussed in relation
to theories predicting the acquisition and mastery of reading.

Partly owing to the status of podcasting as a buzzword and subject of much recent media attention, educational technology researchers and practitioners have been using the term very loosely. Few studies have examined student perceptions and uptake of “podcasting” in the true sense of the word, whereby a syndication protocol such as Really Simple Syndication (RSS) is used to allow students to subscribe to podcast feeds or channels, facilitating the automatic download of new content as it becomes available. The small number of studies that have covered this aspect of podcasting suggest that students generally do not tend to make use of this functionality, but instead prefer to simply download the media files manually. By drawing on research into the usage of RSS and podcasting both inside and outside the field of education, as well as extant literature on university students' usage patterns and behaviors with respect to information and communications technologies (ICTs) and the Internet, the authors postulate a number of possible reasons why podcasting syndication services have not experienced substantial levels of uptake among students to date. They argue that it is premature to dismiss RSS as a distribution mechanism for digital audio content in teaching and learning, and describe a number of examples of educational applications that could potentially make the use of such services worthwhile and valuable to both teachers and students. The authors conclude with suggestions for research to test the theories set forth in the article. 相似文献

RNA interference (RNAi) is a powerful method to silence gene expression in a variety of organisms and is generating interest not only as a useful tool for research scientists but also as a novel class of therapeutics in clinical trials. Here, we report that undergraduate and graduate students with a basic molecular biology background were able to demonstrate conceptual knowledge and technical skills for using RNAi as a research tool upon completion of an intensive 8-wk RNAi course with a 2-h lecture and 5-h laboratory per week. Students were instructed on design of RNAi experiments in model organisms and perform multiweek laboratory sessions based on journal articles read and discussed in class. Using Nicotiana benthamiana, Caenorhabditis elegans, and mammalian cell culture, students analyzed the extent of silencing using both qualitative assessment of phenotypic variations and quantitative measurements of RNA levels or protein levels. We evaluated the course over two semesters, each with a separate instructor. In both semesters, we show students met expected learning outcomes as demonstrated by successful laboratory experiment results, as well as positive instructor assessments of exams and lab reports. Student self-assessments revealed increased confidence in conceptual knowledge and practical skills. Our data also suggest that the course is adaptable to different instructors with varying expertise. 相似文献

Abstract This article outlines a different view of the changing nature of adult learning in the Internet era. The old model of learning—the warehouse—is being replaced by a “just‐in‐time” system of information acquisition. The NRC report focuses too heavily on finding missions for existing institutions and pays too little attention to the pervasive changes in information acquisition and adult learning in all areas. An analysis of existing data demonstrates the relative impact of formal and informal learning and points to opportunities for enhanced adult science learning in the future. In a just‐in‐time world, museums and similar informal learning institutions will need to be less dependent on their physical setting and more focused on learning as the end product. It will also be necessary to find a viable revenue model to support this emerging mission. 相似文献
