It has been suggested that the field of Mind, Brain, and Education (MBE) requires a stable infrastructure for translating research into practice. Hinton and Fischer (2008) point to the academic medical center as a model for similar translational work and suggest a similar approach for linking scientists to research schools. We propose expanding their model to include a formal role for clinicians. Including clinicians who work with children with learning problems brings an important perspective to the translational work. For example, the integration of the concept of “differential diagnosis,” a core precept in clinical medicine, would bring needed diagnostic specificity to the field of MBE. We describe a virtual infrastructure for collaboration, or “collaboratory,” consisting of research scientists, educators, and clinicians, linked to an academic institution. We anticipate that MBE graduates can play a critical role in the collaboratory model. With additional training, they can become “neuroeducators” capable of moving comfortably among the disciplines, building linkages, fostering communication, and facilitating collaboration.  相似文献

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise.  相似文献

The aims of this study were to describe normative values and seasonal variation of body composition in female cyclists comparing female road and track endurance cyclists, and to validate the use of anthropometry to monitor lean mass changes. Anthropometric profiles (seven site skinfolds) were measured over 16 years from 126 female cyclists. Lean mass index (LMI) was calculated as body weight?×?skinfolds?x. The exponent (x) was calculated as the slope of the natural logarithm of body weight and skinfolds. Percentage changes in LMI were compared to lean mass changes measured using dual-energy X-ray absorptiometry (DXA) in a subset of 25 road cyclists. Compared to sub-elite and elite cyclists, world class cyclists were (mean [95% CI]) 1.18?kg [0.46, 1.90] and 0.60?kg [0.05, 1.15] lighter and had skinfolds that were 7.4?mm [3.8, 11.0] and 4.6?mm [1.8, 7.4] lower, respectively. Body weight (0.41?kg [0.04, 0.77]) and skinfolds (4.0?mm [2.1, 6.0]) were higher in the off-season compared to the early-season. World class female road cyclists had lower body weight (6.04?kg [2.73, 9.35]) and skinfolds (11.5?mm [1.1, 21.9]) than track endurance cyclists. LMI (mean exponent 0.15 [0.13, 0.18]) explained 87% of the variance in DXA lean mass. In conclusion, higher performing female cyclists were lighter and leaner than their less successful peers, road cyclists were lighter and leaner than track endurance cyclists, and weight and skinfolds were lowest early in the season. LMI appears to be a reasonably valid tool for monitoring lean mass changes.  相似文献

The twenty-first century has seen unprecedented investment from governments around the world in educational technologies in schools. This paper investigates Australian teachers’ adoption and use of a popular technology that has been extensively supported by governments and school systems: the interactive whiteboard (IWB). The study suggests that a number of the barriers identified in the early days of adoption and use of this technology, such as professional support and access, still remain for many teachers, thereby impeding effective practices. The research also found that primary school teachers were using the technology in diverse ways, in contrast to secondary teachers who were using the IWB mainly for instructionist, presentational purposes. We conclude by considering various ways of reducing the effect of the identified barriers to support implementation of educational technologies in the classroom, especially the next generation of technologies promoted by governments and systems.  相似文献

In this article, we examine the disposition for critical thinking (CT) from three perspectives and analyse the underlying constructs of the disposition for CT, such as one’s ability, sensitivity and inclination to engage in critical, mindful thought. Environmental factors that enhance or inhibit the development of a generalisable disposition for critical thought are discussed. Finally, we present a set of empirically-verified classroom practices that can help to foster a disposition for CT.  相似文献

Past practices shape and limit the design imagination of teachers, pupils, parents, governors, and others concerned with designing modern schools. Bringing histories of education to the table in the participatory design process of new school buildings and curricula is necessary. Schools having an extraordinary past have the potential to draw from that prefigurative practice. This paper reports a case study on how the Kees Boeke School in The Netherlands recently has returned to its own history in addressing the needs of its current and future learners in a redesign project. Through addressing the question of how the redesign might reflect a reconnection with the original vision of education espoused by Boeke—learning in relative freedom, with awareness of responsibilities for own and community’s well-being—the school management, architects, teachers, and students took part in a participatory design process. That process and the resulting school design is discussed. From this case study we argue that past adventures in education can inspire current redesign. Past experiences as well as concerns and beliefs about the future are an inevitable influence on initiatives to realise schools for the future, both for schools with experimental and those with traditional histories.  相似文献

There are many different ways of looking at mass communications’ basic role. Professor William L. Burke, who teaches broadcasting and film courses at Kansas State University, offers as his thesis that the basic task of communications in general is in reducing ambiguity, and that a labeled space modulator is far better than an unlabeled one in doing this!  相似文献
