Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA. 相似文献

The motor control of 49 unmedicated boys clinically diagnosed with ADHD, case‐matched with 49 non‐ADHD boys, was assessed while playing Crash Bandicoot I, a SonyTM Playstation platform computer video game. In Crash Bandicoot participants control the movements of a small‐animated figure through a hazardous jungle environment. Operationally defined measures of motor control were designated by (1) the stage of the game completed (ie, the number of obstacles successfully passed) before losing the figure's ‘life’, (2) the level of complexity that the stage represented and (3) the time taken to get to that point during the video game play. These measures were assessed under contrasting conditions of low or high working memory and distracter loads. Four tasks were administered (totalling 12 trials), incorporating both with and without distracter conditions. For those trials with the distracter, a segment of the television show The Simpsons was simultaneously played on a television screen adjacent to the computer game monitor. A 5‐way MANOVA revealed that ADHD boys took less time to complete their trials under the direct condition (ie, no working memory load) on Crash Bandicoot, compared to their matched non‐ADHD peers. When the task required additional working memory, however, the ADHD boys took significantly longer. Cumulative frequency plots of game performance revealed that in terms of the number of obstacles completed, the control participants successfully navigated more obstacles on the low working memory load task than the ADHD participants, but that the performance of the two groups was less distinguishable on the high working memory load task. The findings have implications for assessment and management of children with ADHD. 相似文献

Student Content Knowledge Increases After Participation in a Hands-on Biotechnology Intervention 总被引：1，自引：1，他引：0
Implementing biotechnology education through hands-on teaching methods should be considered by secondary biology teachers.
This study is an experimental research design to examine increased student content knowledge in biotechnology after a hands-on
biotechnology intervention. The teachers from both school groups participated in, Project Crawfish, a biotechnology professional
development program. Students from both schools completed a pre and post assessment. The classroom was the unit of analysis.
When the assessment was analyzed, each school had statistically significant increases in student content knowledge (p < 0.0001 for the intervention school and p = 0.0481 for the control school). When the schools were compared to each other, a p-value of 0.0543 provided a suggestive relationship that the biotechnology intervention school had a larger increase in student
content knowledge overall. When the assessment was divided into the five components, the intervention school showed significant
increases in all five components. The control school had significant increases in student content knowledge in the PCR and
DNA sequencing components (p = 0.0459, p = 0.0043, respectively). 相似文献

Breakfast skipping is common in adolescents, but research on the effects of breakfast skipping on school performance is scarce. This current cross‐sectional survey study of 605 adolescents aged 11–18 years investigated whether adolescents who habitually skip breakfast have lower end‐of‐term grades than adolescents who eat breakfast daily. Additionally, the roles of sleep behavior, namely chronotype, and attention were explored. Results showed that breakfast skippers performed lower at school than breakfast eaters. The findings were similar for younger and older adolescents and for boys and girls. Adolescents with an evening chronotype were more likely to skip breakfast, but chronotype was unrelated to school performance. Furthermore, attention problems partially mediated the relation between breakfast skipping and school performance. This large‐scale study emphasizes the importance of breakfast as a determinant for school performance. The results give reason to investigate the mechanisms underlying the relation between skipping breakfast, attention, and school performance in more detail. 相似文献

Toddlers' and Preschoolers' Experience in Family Day Care: Age Differences and Behavioral Correlates
Kryzer EM Kovan N Phillips DA Domagall LA Gunnar MR 《Early childhood research quarterly》2007,22(4):451-466
One hundred and twelve children, 56 toddlers and 56 preschoolers, were observed in their family child care settings to determine whether toddlers cared for in settings that also included preschoolers were, relative to the preschoolers, receiving more or less high-quality care and/or whether their functioning at child care appeared to be more or less dependent on aspects of the care providers’ interactions with the children. Quality of care was analyzed along two dimensions: sensitive/supportive care and structured care. Four indices of child functioning at child care were examined: integration in social activities, attention, positive mood, and angry/aggressive behavior. Results indicate that toddlers received less sensitive, supportive care than preschoolers in these mixed-age settings and toddlers were less socially integrated and less engaged in activities in the child care setting. Preschoolers displayed increased levels of angry/aggressive behavior relative to toddlers. In addition, associations of care provider behaviors and child functioning were larger for toddlers than preschoolers, suggesting that toddlers were more dependent on caregiver support for more successful functioning in these family child care settings. For both toddlers and preschoolers, care provider behavior and child functioning was generally poorer in settings with more children. 相似文献

A teacher's capacity to provide sexuality education may be hampered or enhanced by a number of factors. A social–ecological framework can be used to understand these influences, and the present study assesses interpersonal, organisational/institutional and community/policy level influences on teaching sexuality education. Seven focus groups were conducted in 2009 with 41 sexuality education teachers in Minnesota; discussion focused on challenges and the supports teachers experienced. At the interpersonal level, teachers reported both positive and negative interactions with parents, regarding parents as highly influential on school administrators and policy. Teachers reported many organisational level challenges, including their administrators, district policy, and structural factors such as time, financial resources, and diversity in the student body. At the community level, participants overwhelmingly felt that policy changes could be very beneficial to sexuality education in Minnesota, and believed that this support could come from all levels. Findings suggest numerous intervention points to reduce challenges and strengthen supports for teachers, and indicate that a multi-level approach is needed to increase teachers' ability to deliver sexuality education that meets their students' needs and is less onerous for the educator. 相似文献

Women have wanted to play Australian Rules football throughout the game's history, yet given it ritually celebrates male superiority, few have actually played the game. This paper looks at the socio-historical circumstances leading to the eventual establishment of a women's league, based on media coverage and interviews with current and former members. By focusing on their association with two men's football organizations – one that helped them get started, and the other that allowed them to use their men's clubs as home bases for their women's teams – it also explores the extent to which playing a male-dominated game means having to play on male-defined terms. 相似文献

This study examined the long-term effects of the 11+ on physical performance in adolescent male football (soccer) players. Eighty-two 14- to 16-year-old male football players (11+ = 42 players, control = 40 players) participated. Teams were randomised to control (CON) and intervention (INT) groups. INT applied the 11+ injury prevention programme for 30 weeks at least twice a week as a warm-up. CON performed their standard warm-up. Motor performance tests were conducted 1 week prior and 1 week after the competition season. We used magnitude-based inferences and linear mixed-effects models to analyse performance test results. INT showed superior results compared to CON in the vertical jump height 7.5% (95%-CI 4.4%, 10.7%), the Bosco 15-s-jump test 7.2% (95%-CI 2.2%, 12.4%), and the Illinois agility test ?2.6% (95%-CI ?4.1%, ?1.1%). Possibly beneficial effects in favour of INT were found in the 9.1 m sprint test ?3.1% (95%-CI ?6.1%, 0.1%). Possibly harmful effects (i.e. in favour of CON) were observed in the dribbling test 2.8% (95%-CI ?0.8%, 6.4%). The 11+ warm-up programme can improve different performance measures in football players. Coaches might implement additional dribbling drills next to the 11+ to achieve improvements observed in dribbling ability when using a regular warm-up programme. 相似文献

Literuture Matters was a two‐year, national programme in England designed to promote partnerships between schools library services and initial teacher training institutions. Its aim was to raise awareness of the role of the schools library service in promoting children's books and reading for pleasure. There were positive effects, in the short term, on student teachers, teacher educators and library staff. Potentially sustainable partnerships were developed, but structures and funding are needed to ensure a long term impact over new teachers' careers. 相似文献

Guiding inquiry learning has been shown to increase knowledge gains. Yet, little is known about the effect of guidance on attitudes and behaviours, its interaction with student attributes, and transfer of impact once guidance is removed. We address these gaps in the context of an interactive Physics simulation on electric circuits (https://phet.colorado.edu/en/simulation/circuit-construction-kit-dc). 49 students in the Non-Directive condition received a set of goals to focus their inquiry, in addition to implicit support built into the simulation. 48 students in the Directive condition received, in addition to these, also detailed directions and prompts. Log-file analysis found that directive support led to more formal testing and less exploration. Clustering identified two groups of learners: one with higher incoming knowledge (Higher Knowledge), the other with higher incoming perceptions of competence and control (Higher PoCC). Working with the simulation improved knowledge and attitudes across cluster groups, so that prior differences all but disappeared. With regard to guidance, adding directive support improved knowledge gains for the Higher Knowledge group, yet suppressed their attitudinal growth. The same support had no effect on knowledge gains for the Higher PoCC group, yet it boosted their attitudinal growth. A transfer activity, where directive support was no longer available, found that impact on attitudes carried forward, yet impacts on behaviours and knowledge were short-lived. Overall, the study highlights the complex interaction between guidance and student attributes. For some, supporting short-term knowledge gains may inadvertenly lead to longer term negative impact on attitudes towards inquiry. 相似文献
