The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  相似文献

Results of an assessment to identify potential barriers to sustainable agriculture on American Indian reservations in the Western United States     

Loretta Singletary  Staci Emm  Fara Ann Brummer  George C. Hill  Steve Lewis  Vicki Hebb 《The Journal of Agricultural Education and Extension》2016,22(4):375-387

Purpose: This paper reports the results of survey research conducted with tribal producers between 2011 and 2012 on 19 of the largest American Indian reservations in Idaho, Nevada, North Dakota, Oregon, South Dakota, and Washington. The purpose of the research was to identify potential barriers to sustainable agriculture on reservation lands. This article reports the results of this research in an effort to promote Extension professionals' understanding of these barriers, which may help to improve outreach programs on American Indian reservations. Understanding the obstacles to sustaining agriculture that American Indian tribes face may inform international agricultural outreach efforts to increase food security targeting indigenous and tribal peoples worldwide.

Design/Methodology/Approach: American Indian agricultural producers comprised the study group. Study objectives included: (1) identify agricultural and natural resource issues of greatest concern to a self-selected sample of tribal agricultural producers on reservation lands; (2) evaluate access to Extension and other US Department of Agriculture outreach and assistance programs; and (3) evaluate the quality of these programs in terms of their relativity to tribal needs.

Findings: Study results indicate that tribal agricultural producers surveyed ranked 29 of 39 agricultural and natural resource issues as a concern. Similarly, they rated access to and quality of outreach programs as fair. Further, tribal producers operating on reservation trust land rated issues more severely than did tribal producers operating on fee simple lands.

Practical Implications: Results of this research will help Extension and other outreach professionals to understand the barriers indigenous and tribal peoples face in sustaining agricultural operations, particularly tribal groups living on federally reserved trust lands, such as American Indians. An increased understanding can inform agricultural policy-makers and outreach professionals in improving programs designed to increase agricultural sustainability, improve food security, enhance economic well-being and improve quality of life of indigenous and tribal peoples worldwide.

Originality/Value: This research provides important information to agricultural policy-makers and Extension professionals striving to sustain agricultural productivity and enhance food security with indigenous and tribal peoples.  相似文献   

Defining the nature of blended learning through its depiction in current research     

Karen Smith  John Hill 《高等教育研究与发展》2019,38(2):383-397

ABSTRACT

Blended learning has been a feature of higher education practice and research for almost two decades. This article takes stock of current blended learning research, contributing to the growing number of meta-analyses of higher education and blended learning research more generally, through a review of ninety-seven articles relating to blended learning in higher education published in fifteen journals between 2012 and mid-2017. The review focused on where and when the articles were published; their provenance, scale, scope; methodological approach; the broad research themes; and definition of blended learning used. The review shows that despite its ubiquity, blended learning’s definition is all-encompassing; its spread is global but research is dominated by key players; it is of technical interest; and its research is small-scale, individually focused, seeking to evidence the benefits of blended learning. The article concludes with recommendations of how higher education research could provide institutions with evidence to ensure their ‘best of blends’.  相似文献   

Familial patterns of learning disabilities     

Sandra Smith 《Annals of dyslexia》1992,42(1):141-158

Extended families of 12 young adults (9 LD, 3 non-LD) were given a battery of tests and questionnaires, and 131 persons, ranging in age from 6 to 85, were classified as LD or non-LD on the basis of subtest scores 1 SD below the mean or less on subtests of the PIAT and WRAT achievement tests. Pedigree analysis indicated that LD was strongly familial, with the most probable mode involving a major gene effect, but the type of disability (reading/ math) was not directly inherited. Autoimmune disorders were significantly correlated (P<.005) with LD, especially in families in which LD remained a major handicap into adulthood, a trait that also varied between families. In two of the LD families, adults showed little evidence of the reading/spelling deficits they had shown when tested as children, while adults in other families failed to make gains in reading and spelling.  相似文献   

Disruptive silence: deepening experiential learning in the absence of technology     

Carol A. Smith  Rodney Parks  Jesse Parrish  Ryan Swirski 《Journal of Adventure Education & Outdoor Learning》2018,18(1):1-14

Technology plays an integral role in the lives of the majority of the US population. As technology becomes integrated into young people’s lives, questions arise regarding its effects on learning. This exploratory study draws on interviews with students who attend university in the United States to determine how separating students from technology deepens experiential learning. Participants were interviewed following a study abroad course to New Zealand, during which they were disconnected from technologies such as cell phones, the Internet and social media. In the interviews, students discussed their feelings of being disconnected and describe how disconnecting impacted their overall experience. Participants agreed that disconnecting from technology had positive effects on experiential learning and the global experience. Major themes that emerged include students’ enhanced immersion and engagement, the value of disconnection in providing opportunities for personal growth and the difficulty of initial separation from technology as a result of conditioning.  相似文献

Pedagogical and technological augmentation of mobile learning for young children interactive learning environments     

Yanghee Kim  Diantha Smith 《Interactive Learning Environments》2017,25(1):4-16

The ubiquity and educational potential of mobile applications are well acknowledged. This paper proposes six theory-based, pedagogical strategies to guide interaction design of mobile apps for young children. Also, to augment the capabilities of mobile devices, we used a humanoid robot integrated with a smartphone and developed an English-learning app that applied the design strategies to this environment. Our observations of children's one-on-one use support the promise of the strategies and the combined use of robots and mobile devices to be a viable option to help optimize mobile learning.  相似文献   

Opening classroom interaction: the importance of feedback     

Heather Smith  Steve Higgins 《Cambridge Journal of Education》2006,36(4):485-502

Efforts to encourage ‘interactive practice’ in the National Literacy (NLS) and Numeracy (NNS) Strategies in the UK, have led to an emphasis on teacher questions. Recent research into classroom interactions, however, indicate that the pattern of interaction remains largely unchanged since the introduction of these strategies in terms of the type and amount of questions teachers are asking, and the opportunities for extended pupil participation. This article uses evidence gathered from a large‐scale research project examining classroom interactions during literacy and numeracy lessons, and the researchers' critical reflections upon this process, to examine conceptions of interactive pedagogy. It is argued that in order to ‘open’ classroom interaction, emphasis should be less on the questions teachers ask, and more on the manner with which teachers react to pupils' responses to questions. Episodes of classroom interaction from video recorded literacy and numeracy lessons taken as part of the study are used to support this argument. They present evidence of teacher behaviours in reaction to pupils' responses which succeed in facilitating a more interactive learning environment. The implication that such behaviour will contribute towards a model of effective interactive practice is also discussed.  相似文献
