As the prevalence of childhood obesity increases, it is important to examine possible differences in psychosocial correlates of physical activity between normal weight and overweight children. The study examined fatness (weight status) and (aerobic) fitness as Enabling factors related to youth physical activity within the Youth Physical Activity Promotion Model (YPAP). Youth ages 9–11 years (N = 1,103) completed the Children’s Physical Activity Correlates survey and the Children’s Physical Activity Questionnaire. Structural equation modeling was used to analyze the relationships among variables. Overweight children reported lower scores on global self-esteem, perceived competence, attraction to physical activity, and parental influence (Cohen’s d ranging from .23 to .45 for girls; Cohen’s d ranging from .31 to .43 for boys). Weight status showed a small positive direct effect on physical activity (standardized path coefficient = .11), but did not show effects on psychosocial correlates (p > .05). Furthermore, aerobic fitness proved to be a stronger Enabling factor (standardized path coefficient = .26) than weight status within the YPAP model. Future research using the YPAP model may extend its utility as an evaluation framework for youth physical activity intervention studies. 相似文献

This article presents a discussion of research and theoretical perspectives on creativity and instructional design, offering
a conceptual model of the connection between these two constructs that was originally proposed in the dissertation work of
the first author (Clinton, Creativity and design: A study of the learning experience of instructional design and development
graduate students, Unpublished doctoral dissertation, University of Georgia, Athens, 2007) and that we call the Design/Creativity
Loops (DCL) model. Central to the model is a representation of the iterative, looping problem-solving cycle that can include
established stages of creative thinking. As an instructional designer is routinely confronted with the next task or design
problem in a project, these tasks or problems spawn iterative mental excursions that are opportunities for creative thinking.
This article also explores ways that the design and development process can benefit from an emphasis on creativity and offers
suggested directions for future research. 相似文献

PurposeThis systematic review aimed to describe objective sleep parameters for athletes under different conditions and address potential sleep issues in this specific population.MethodsPubMed and Scopus were searched from inception to April 2019. Included studies measured sleep only via objective evaluation tools such as polysomnography or actigraphy. The modified version of the Newcastle–Ottawa Scale was used for the quality assessment of the studies.ResultsEighty-one studies were included, of which 56 were classified as medium quality, 5 studies as low quality, and 20 studies as high quality. A total of 1830 athletes were monitored over 18,958 nights. Average values for sleep-related parameters were calculated for all athletes according to sex, age, athletic expertise level, training season, and type of sport. Athletes slept on average 7.2 ± 1.1 h/night (mean ± SD), with 86.3% ± 6.8% sleep efficiency (SE). In all datasets, the athletes’ mean total sleep time was <8 h. SE was low for young athletes (80.3% ± 8.8%). Reduced SE was attributed to high wake after sleep onset rather than sleep onset latency. During heavy training periods, sleep duration and SE were on average 36 min and 0.8% less compared to pre-season and 42 min and 3.0% less compared to in-season training periods, respectively.ConclusionAthletes’ sleep duration was found to be short with low SE, in comparison to the general consensus for non-athlete healthy adults. Notable sleep issues were revealed in young athletes. Sleep quality and architecture tend to change across different training periods. 相似文献

Effective and efficient teams communicate, collaborate, and perform, even if these teams are not co‐located. Although much is known about enabling effectiveness on face‐to‐face teams, considerably less is known about similarly enabling effectiveness on virtual teams. Yet the use of virtual teams is common and will likely become more commonplace as organizations continue to update and use increasingly sophisticated technology. Cohort and individual trust between team members is a significant component on most effective teams, virtual or face‐to‐face. This paper examines research on virtual teams and trust across disciplines, including management, e‐learning, business communication, decision making, human resource management, psychology, and IT, to identify major characteristics that increase our knowledge of how to establish and maintain trust in the virtual environment and on virtual teams. 相似文献

While gamification and game-based learning have both been demonstrated to have a host of educational benefits for university students, many university educators do not routinely use these approaches in their teaching. Therefore, this systematic review, conducted using the PRISMA guidelines, sought to identify the primary drivers and barriers to the use of gamification and game-based learning by university educators. A search of multiple databases (Web of Science, Scopus and EBSCO (Business Source Complete; ERIC; Library, Information Science & Technology Abstracts)) identified 1330 articles, with 1096 retained after duplicates were removed. Seventeen articles (11 quantitative, two mixed-methods and four qualitative) were included in the systematic review. The primary drivers described by the educators that positively influenced their gamification and game-based learning usage were their beliefs that it encourages student interactions and collaborative learning; provides fun and improves engagement; and can easily be used by students. Alternatively, the university educators' major barriers included a lack of time to develop gamification approaches, lack of proven benefits and classroom setting issues. Many of these and other less commonly reported drivers and barriers can be categorised as attitudinal, design-related or administrative in nature. Such categorisations may assist university educators, teaching support staff and administrators in better understanding the primary factors influencing the utilisation of gamification and game-based learning and develop more effective strategies to overcome these barriers to its successful implementation.
Practitioner notes
What is already known about this topic
- Gamification and game-based learning may have many benefits for university students.
- The majority of university educators do not routinely use gamification and game-based learning in their teaching.
What this paper adds
- University educators' major drivers that positively influence the use of gamification and game-based learning include their perceptions that it encourages student interactions and collaborative learning, provides fun and improves engagement and can easily be used by students.
- University educators' major barriers that negatively influence the use of gamification and game-based learning include their perceptions of a lack of time to develop gamification approaches, lack of proven benefits and classroom setting issues.
- These drivers and barriers may be classified as attitudinal, design-related and administrative, with these categories providing a useful way for universities to develop strategies to better support educators who wish to use these approaches in their teaching.
Implications for practice and policy
- Attitudinal factors such as university educators' intention to use gamification and game-based learning are influenced by a host of their perceptions including attitude, perceived usefulness and ease of use.
- A range of design-related and administrative barriers may need to be overcome to increase the use of gamification and game-based learning in the university sector.
