Abstract

The purpose of this study was to examine the effect of parental involvement in a school-based program about exercise and nutrition. One fifth grade and one sixth grade class were randomly assigned to each of the three different treatment conditions, a school-and-home condition (n = 45), a school-only condition (n = 43), and a control condition (n = 44). In the school-and-home condition, the children's parents were also asked to participate in nutritional and exercise activities at home as a family “home team.” A multivariate analysis of variance on change scores was completed on the following variables: height, weight, skinfold, sit-and-reach, sit-ups, mile run, exercise knowledge, saturated fat, cholesterol, percent calories from fat, percent calories from carbohydrates, and nutrition knowledge. There was a significant difference among groups. The school-and-home and school-only groups showed significantly greater improvement than the control group but were not significantly different from each other. Univariate analyses on posttest scores indicated that the school-and-home children scored significantly higher than the control group on sit-and-reach flexibility and nutrition knowledge. The results indicate that including the family was primarily effective in facilitating children's improvements in flexibility and nutrition knowledge rather than in diet and exercise behaviors.  相似文献   

The effect of periodized resistance training on accelerative sprint performance

The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6–10%). However, both groups increased 0–10 m sprint times (experimental group = 6%; control group = 3%) while 10–20 m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0–10 m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training.  相似文献   

Is passive drag dependent on the interaction of kayak design and paddler weight in flat-water kayaking?

Abstract

Drag is one of the major factors that influences kayaking performance. To focus on the drag of the kayak’s hull shape and the paddlers’ weight per se, the passive drag (D_p) was measured on a flat-water sprint course for one paddler with added weights. D_p was measured by an electromechanical towing device using a load cell, at incremental and constant velocities from 2.78 to 5.56 m/s. Three kayaks of different sizes and shapes (Nelo® K1 Quattro-M, ML, and L) were used and the paddlers’ body weight was adjusted with weights so the total paddler weight in the kayak was 65, 75, and 85 kg. The mean D_p increased by the power function of D = kvⁿ (mean R² = .990; SD .006). The D_p went from 21.37?±?1.29 N at 2.78 m/s to 89.32?±?6.43 N at 5.56 m/s. For the two lighter weighted kayaks (65 and 75 kg), the lowest D_p was observed with different kayak sizes (M, ML, or L) depending on the target velocity. The manufacturers suggest that paddlers should select a kayak size according to their body weight to minimise drag; however, the results of this study suggest that target velocities, and thus competition distance should also be factored into kayak selection.  相似文献   

More than just fun: a place for games in playful learning / Más que diversión: el lugar de los juegos reglados en el aprendizaje lúdico

Games play a significant role in childhood, fuelling hours of engagement and social interaction, and probably much learning as well. Board games, card games and outdoor games (such as Tag) first come to mind, but more recently, games have also gone digital. In this piece, we offer a new perspective by placing games within the established construct of ‘playful learning’. We review key elements of playful learning and the two subtypes: free play and guided play. We suggest that games promote learning in ways similar to other playful learning situations. Games involve fun, a sense of curiosity and an inhibition of reality, in active, engaging, meaningful and socially interactive contexts. We argue that games therefore belong alongside free play and guided play to form a trio of playful learning experiences. This perspective adds to a growing understanding of the role of games in supporting children’s learning and development.  相似文献

Modeling maternal emotion-related socialization behaviors in a low-income sample: Relations with toddlers’ self-regulation     

Holly E. Brophy-Herb  Kathy Stansbury  Erika Bocknek  Mildred A. Horodynski 《Early childhood research quarterly》2012

This study tested the validity of an emotion-related parenting construct, indicated by six key emotion-related socialization behaviors (ERSBs) occurring in daily, developmentally salient parenting in a low-income sample of mothers (N = 123) of toddlers, and examined the relationship between the ERSB construct and toddlers’ self-regulation. Structural equation modeling confirmed a latent emotion-related parenting construct, indicated by observed maternal warmth and supportiveness, observed emotional responsivity in the home, maternal report of mealtime socialization practices, observed maternal use of mental state language and emotion talk, and maternal report of positive self-expressivity in the family. Emotion-related parenting significantly related to toddlers’ effective coping and delay of gratification (medium effect sizes). Maternal demographic risk was negatively related to emotion-related parenting (large effect size) but positively related to toddlers’ effective coping (medium effect size); toddler age and gender were not significantly related to ERSBs. Results suggest that maternal ERSBs are cohesive in a low-income population, reflecting emotion-related parenting, and play a role in economically at-risk toddlers’ self-regulation. Implications for parenting and family support programs as well as implications for future research are discussed.  相似文献   

Predicting acceptance of diversity in pre-kindergarten classrooms     

Kay Sanders  Jason Downer 《Early childhood research quarterly》2012

This study examined classroom-level contributors to an acceptance of diversity in publicly supported pre-kindergarten classrooms across 11 states. Classroom composition, process quality, and teacher characteristics were examined as predictors of diversity-promoting practices as measured by the ECERS-R, acceptance of diversity construct. Findings reveal that emotional climate, bilingual classrooms, family poverty levels within classrooms, and Latino teacher ethnicity are predictive of diversity-promoting classrooms; while classroom-level ethnic sameness to teacher prohibits diversity-promoting practices in pre-kindergarten classrooms.  相似文献   

Goodbye Yellow Brick Road: Challenging the Mythology of Home in Children’s Literature     

Melissa B. Wilson  Kathy G. Short 《Children‘s Literature in Education》2012,43(2):129-144

The myth of home is what distinguishes children??s literature from adult novels (Wolf 1990). Nodelman and Reimer (The Pleasures of Children??s Literature, 2003) write that while ??the home/away/home pattern is the most common story line in children??s literature, adult fiction that deals with young people who leave home usually ends with the child choosing to stay away?? (pp. 197?C198). In a critical content analysis of recent award-winning middle reader novels from the United States, the United Kingdom, and Australia, a new pattern was observed. This pattern, called a postmodern metaplot, begins with the child being abandoned, rather than the child leaving the home. The child??s journey is to construct a home within a postmodern milieu complete with competing truths and failed adults. Ultimately, the child??s postmodern journey ends with very modern ideal of the child leading the adults to a hopeful ending, a home. The article explores the changing roles of childhood and adulthood in children??s literature and questions if the mythology of home can be undone.  相似文献   

The emergence of reading literacy in post-primary teacher education: from the background to the foreground     

Brian Murphy  Paul F. Conway  Rosaleen Murphy  Kathy Hall 《欧洲师范教育杂志》2014,37(3):331-347

While recognising the fact that historically teacher education and adolescent literacy are two fields that have had limited intellectual contact, the development of reading literacy is increasingly now accepted internationally as a core responsibility of all teachers and teacher educators. Adopting a socio-cultural perspective, this paper, drawn from the Learning to Teach Study, focused on the beliefs, knowledge and experiences regarding reading literacy of Irish post-primary student teachers on one initial teacher education (ITE) programme. The data were collected through three interviews with each of 17 student teachers. Results suggest that the surveyed student teachers had some concerns about their own literacy, had narrow conceptions of literacy, tended not to see it as their responsibility, held a minimal threshold view of literacy and viewed new digital technologies as a resource and motivator for their students’ literacy learning. Results are discussed in terms of how student teachers’ knowledge of literacy in ITE programmes could be reframed, extended and deepened.  相似文献   

System leaders using assessment for learning as both the change and the change process: developing theory from practice     

Anne Davies  Kathy Busick  Sandra Herbst  Ann Sherman 《Curriculum Journal》2014,25(4):567-592

Many schools and school systems have been deliberately working towards full implementation of Assessment for Learning for more than a decade, yet success has been elusive. Using a leader's implementation of Assessment for Learning in one school as an illustration, this article examines eight positional leaders’ experiences as they implemented both the ‘spirit and the letter’ of Assessment for Learning at all levels. This longitudinal qualitative research study draws on the experiences of leaders from Alberta, British Columbia, Germany, Georgia, Hawai`i, Manitoba, New Zealand and Ontario. The authors identify five findings that show how positional leaders use Assessment for Learning as the focus for system-wide change, as well as the change process itself.  相似文献
