The Future of English     

Chris Davies 《English in Education》1991,25(3):28-31

The unity of "unitary" English, subsuming "language" and "literature", has always been a central tenet of NATE thinking and a basic assumption of most progressive practice, and is now enshrined in the National Curriculum¹. In this article, however, Chris Davies makes the scandalous proposal that the time has come when "language" and "literature", radically transformed, would be better separated.  相似文献

Do physical activity beliefs differ by age and gender?   总被引：1，自引：0，他引：1  

Rhodes RE  Blanchard CM  Blacklock RE 《运动与训练心理学杂志》2008,30(3):412-423

Age and gender are consistently related to physical activity (PA), yet theoretical explanation for these associations is scant. The present study compared the mean values and correlations of a population sample, divided by gender and age group, with respect to theory of planned behavior beliefs (behavioral, normative, and control) and PA. Participants were a sample (N=6,739) of adults (M age=49.65, SD=16.04) who completed measures of social and health demographics, theory of planned behavior beliefs, and self-reported PA. Mean analyses identified greater perceived control over PA for seniors than for young and middle-aged adults (N>.025). Belief-behavior correlations, however, were not different across age and gender in 24 of 26 tests (q<.19). Thus, PA beliefs are invariant across age and gender with the exception of mean levels of perceived control, which are lower among younger adults than older adults. Factors such as early parenthood and career demands were considered the likely reasons for differences. Overall, the evidence suggests that adapting theoretical models for specific age groups or based on gender may not be necessary.  相似文献   

Biodiversity for Beginners     

Chris Du Feu 《Teaching Statistics》2006,28(3):66-70

Biodiversity is a difficult concept. It can be introduced to young children successfully, laying the foundations for further study in later years. This article describes one practical activity for 5‐ and 6‐year‐old children.  相似文献

Shared Reading within an Apprenticeship Approach to Reading     

Robin Campbell 《Educational studies》1992,18(2):173-183

Williamson & Carrington argued, in a recent edition of Educational Studies, the need for a major investigation of the effectiveness of an apprenticeship approach to reading. This paper considers some of the problems associated with such investigations. It also seeks to clarify some of the terminology in the whole language repertoire before looking in detail at shared reading as an important part of such approaches. The article concludes by suggesting that ethnographic studies are the means by which issues in the teaching and learning of reading may best be clarified, and teachers and children assisted.  相似文献   

Creating Better Learners Through Learning Science: A Sample of Methods     

Chris Brown 《图书馆管理杂志》2018,58(4):375-381

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning.  相似文献

Postural stability,clicker reaction time and bow draw force predict performance in elite recurve archery     

Wayne Spratford  Rhiannon Campbell 《European Journal of Sport Science》2017,17(5):539-545

Recurve archery is an Olympic sport that requires extreme precision, upper body strength and endurance. The purpose of this research was to quantify how postural stability variables both pre- and post-arrow release, draw force, flight time, arrow length and clicker reaction time, collectively, impacted on the performance or scoring outcomes in elite recurve archery athletes. Thirty-nine elite-level recurve archers (23 male and 16 female; mean age?=?24.7?±?7.3 years) from four different countries volunteered to participate in this study prior to competing at a World Cup event. An AMTI force platform (1000Hz) was used to obtain centre of pressure (COP) measurements 1s prior to arrow release and 0.5s post-arrow release. High-speed footage (200Hz) allowed for calculation of arrow flight time and score. Results identified clicker reaction time, draw force and maximum sway speed as the variables that best predicted shot performance. Specifically, reduced clicker reaction time, greater bow draw force and reduced postural sway speed post-arrow release were predictors of higher scoring shots. It is suggested that future research should focus on investigating shoulder muscle tremors at full draw in relation to clicker reaction time, and the effect of upper body strength interventions (specifically targeting the musculature around the shoulder girdle) on performance in recurve archers.  相似文献   

The effects of attentional focus instructions on punching velocity and impact forces among trained combat athletes     

Israel Halperin  Dale W. Chapman  David T. Martin  Chris Abbiss 《Journal of sports sciences》2017,35(5):500-507

Research indicates that instructing athlete’s to focus on bodily movements (internal focus of attention [IFA]) may hinder performance, whereas instructing them to focus on the movement outcome (external focus of attention [EFA]) often enhances performance. Despite the importance of instructions in striking combat sports, limited research has examined the influence of IFA and EFA on performance in well-trained combat athletes. This study investigated the effects of different instructional cues on punching velocity (m · s^?1) and normalised impact forces (N · kg^?1) among intermediate (n = 8) and expert (n = 7) competitive boxers and kickboxers. Athletes completed three rounds of 12 maximal effort punches delivered to a punching integrator on three separate days. Day one was a familiarisation session with only control instructions provided. In the following two days athletes randomly received IFA, EFA or control instructions prior to each of the three rounds. Athletes punching with EFA were 4% faster and 5% more forceful than IFA (P < 0.05), and 2% faster and 3% more forceful than control (P < 0.05). Furthermore, experts punched 11% faster and with 13% greater force compared with intermediate athletes (P < 0.05). EFA led to a positive effect on punching performance and should be favoured over IFA and control instructions.  相似文献
