The differential effects of four task selectionmethods on training efficiency and transfer incomputer-based training for Air Traffic Controlwere investigated. A non-dynamic condition, inwhich the learning tasks were presented to theparticipants in a fixed, predeterminedsequence, was compared to three dynamicconditions, in which learning tasks wereselected on the basis of performance, mentaleffort, and a combination of both (i.e., mentalefficiency). Using the 3-factor mentalefficiency formula of Tuovinen and Paas (2004, this issue), the hypothesis that dynamic taskselection leads to more efficient training thannon-dynamic task selection was confirmed.However, the hypothesis that dynamic taskselection based on mental efficiency leads tomore efficient training than dynamic taskselection based on performance or mental effortalone was not supported. The results arediscussed in light of the theoretical frameworkand suggestions are given for futureresearch.  相似文献

Maximising the language and learning link in computer learning environments     

Catherine McLoughlin  & Ron Oliver 《British journal of educational technology : journal of the Council for Educational Technology》1998,29(2):125-136

In studies on the implementation and educational uses of computers there are reports of changes in students' behaviour as a result of working with computers (Rowe, 1993; Crook, 1994). Social, collaborative and dialogic exchanges have been observed as students engage in tasks around computers. This research provides evidence that the computer is a social facilitator in the sense that it provides opportunities for collaboration, group work and interaction which fosters cognitive change (Wild, 1995).
This article recognises the social role of the computer, and supports the view that computers can be used to facilitate learning through language. There is growing awareness that if we are to realise the full potential of computers in education, consideration must be given to their role as catalysts in the learning process, rather than technological tools (Hawkridge, 1990). Computer assisted learning has progressed through many phases, and through investigation of underlying theoretical frameworks it is possible to recognise the change of focus from individual accounts of learning to social perspectives.
Theoretical frameworks which emphasise the social dimensions of learning (Vygotsky, 1978) legitimise the link between computers, language use and learning and indicate that computers must be integrated into the social life of classrooms if their pedagogical benefits are to be realised.  相似文献   

Social class and participation in further education: evidence from the Youth Cohort Study of England and Wales   总被引：2，自引：1，他引：1  

Ron Thompson 《British Journal of Sociology of Education》2009,30(1):29-42

This paper examines the class distribution of young people, aged 16–17 years, in colleges of further education (FE) using data from the Youth Cohort Study. It finds that, contrary to popular perceptions of FE colleges as being for ‘other people’s children’, middle‐class students as well as working‐class students are well represented. However, this does not imply that FE colleges are institutions of choice; middle‐class representation is often related to lower achievement and, for low‐achieving working‐class students, leaving education entirely is more likely than entry to FE. These findings are explored using notions of habitus and field. Their relationship with studies of the education of middle‐class children is also discussed, and the paper suggests that research on class in FE colleges must come to terms with middle‐class presence.  相似文献   

Can Inquiry and Reflection be Contagious? Science Teachers, Students, and Action Research     

Kimberly Lebak  Ron Tinsley 《Journal of Science Teacher Education》2010,21(8):953-970

This study reports the transformations of 3 science teachers who conducted action research projects following a model, unique to our graduate program, which follows the theoretical tenets of adult and transformative learning theory. Teachers video their teaching, engage in weekly peer group collaborative reflection sessions, collaborate with students, and consult with other sources to identify goals for improving their teaching practices, develop action plans, and analyze the results of their actions. As a result of this process, all 3 teachers changed their pedagogical approach from a teacher centered textbook driven approach to a student centered inquiry based approach. Implications of using this model as a powerful means of professional development for science teachers are explored.  相似文献   

Assessing effectiveness and efficiency of academic interventions in school psychology journals: 1995–2005     

Ron Bramlett  Gary L. Cates  Elena Savina  Brittni Lauinger 《Psychology in the schools》2010,47(2):114-125

This article reviews research in the four major school psychology journals: Journal of School Psychology, Psychology in the Schools, School Psychology Quarterly, and School Psychology Review. The function of the review was to provide school psychologists with a summary of academic interventions published through years 1995–2005, synthesize the commonalities of empirically based interventions, and report on the extent to which each article provides the reader the opportunity to understand the effects of the intervention with regard to the amount of instructional time required to implement it. Results of the review suggest that reading is most heavily investigated followed by math and, to a much lesser degree, written expression. Moreover, studies use a variety of designs including single subject and group designs. Finally, it is clear that a limited number of studies evaluate the effectiveness of an intervention with regard to the amount of instructional time needed to implement the intervention. In light of these findings and in addition to the two major functions of the review, recommendations for practice and future research are presented. © 2009 Wiley Periodicals, Inc.  相似文献   

Dietary supplements     

Ron J Maughan  Doug S King  Trevor Lea 《Journal of sports sciences》2013,31(1):95-113

For the athlete training hard, nutritional supplements are often seen as promoting adaptations to training, allowing more consistent and intensive training by promoting recovery between training sessions, reducing interruptions to training because of illness or injury, and enhancing competitive performance. Surveys show that the prevalence of supplement use is widespread among sportsmen and women, but the use of few of these products is supported by a sound research base and some may even be harmful to the athlete. Special sports foods, including energy bars and sports drinks, have a real role to play, and some protein supplements and meal replacements may also be useful in some circumstances. Where there is a demonstrated deficiency of an essential nutrient, an increased intake from food or from supplementation may help, but many athletes ignore the need for caution in supplement use and take supplements in doses that are not necessary or may even be harmful. Some supplements do offer the prospect of improved performance; these include creatine, caffeine, bicarbonate and, perhaps, a very few others. There is no evidence that prohormones such as androstenedione are effective in enhancing muscle mass or strength, and these prohormones may result in negative health consequences, as well as positive drug tests. Contamination of supplements that may cause an athlete to fail a doping test is widespread.  相似文献

Running economy,mechanics, and marathon racing shoes

ABSTRACT

The choice of marathon racing shoes can greatly affect performance. The purpose of this study is to metabolically and mechanically compare the consumer version of the Nike Vaporfly 4% shoe to two other popular marathon shoes, and determine differences in running economy. Nineteen subjects performed two 5-minute trials at 4.44m/s wearing the Adidas Adios Boost (AB), Nike Zoom Streak (ZS), and Nike Vaporfly 4% (VP) in random order. Oxygen uptake was recorded during minutes 3–5 and averaged across both shoe trials. On a second day, subjects wore reflective markers, and performed a 3-minute trial in each shoe. Motion and force data were collected over the final 30 seconds of each trial. VP oxygen uptake was 2.8% and 1.9% lower than the AB and ZS. Stride length, plantar flexion velocity, and center of mass vertical oscillation were significantly different in the VP. The percent benefit of the VP over AB shoe was predicted by subject ground time. These results indicate that use of the VP shoe results in improved running economy, partially due to differences in running mechanics. Subject variation in running economy improvement is only partially explained by variation in ground time.  相似文献
