The effects of exergaming on physical activity in a third-grade physical education class

We compared the effects of exergaming and traditional physical education on physical activity among 4 active children who were not overweight and who had experience with the exergaming activities prior to the study. Results showed that exergaming produced substantially higher percentages of physical activity and opportunity to engage in physical activity. In addition, an evaluation of the exergaming equipment showed that exergaming stations were associated with differential levels of physical activity across participants.     

Perfectionism for children,anti-perfectionism for adults

This paper explores the debate between perfectionists and anti-perfectionists in the context of children. It suggests that the most influential and compelling arguments in favour of anti-perfectionism are adult-centric. It does this by considering four leading reasons given in favour of anti-perfectionism and shows that none apply in the case of children. In so doing, the paper defends a perfectionist account of upbringing from the attacks made against perfectionism more generally. Furthermore, because the refutation of the various anti-perfectionist arguments are made exclusively dealing with children, the paper suggests that the perfectionist view of upbringing is compatible with anti-perfectionist restrictions on dealing with adults. This dual view combining perfectionism for children and anti-perfectionism for adults is referred to as restricted perfectionism.     

An experimental investigation of physical education teachers’ and coaches’ reactions to weight-based victimization in youth

Objectives

Overweight youth are frequent targets of weight-based victimization during Physical Education (PE) and sports. In addition, previous research indicates that teachers’ perceptions and expectations may influence their likelihood of intervening during victimization, and physical educators may endorse biased perceptions and expectations of overweight youth. Despite this evidence, no research has examined how physical educators respond to weight-based victimization of their students. Thus, the current study examined PE teachers’ and coaches’ responses to different types of victimization involving average weight and overweight students.

Design

This study utilized an experimental design that assessed participants’ reactions to situations of weight-related victimization using hypothetical scenarios accompanied by photographs of youth.

Methods

PE teachers and sport coaches (N = 162) were randomly presented with a scenario and follow-up questions about an average weight or an overweight student. Each participant completed two conditions: one with a male target, and one with a female target.

Results

Participants were more likely to take action when overweight female students were victims of bullying, specifically in situations of verbal and relational victimization. Male participants were less likely to respond to victimization than female participants.

Conclusions

Findings suggest the importance of increasing awareness about weight-based victimization and its consequences, especially among male physical educators. Implications for the psychological, social, and physical development of overweight youth are discussed.     

中学生消费价值观在家庭理财教育方式与消费决策风格之间的中介作用

目的：考察中学生消费价值观在家庭理财教育方式与消费决策风格之间的中介作用。方法：377名中学生完成了中学生消费价值观问卷、家庭理财教育方式问卷和中学生消费决策风格问卷。结果：父母积极的教育方式可通过树立合理的消费价值观来促进中学生形成理性的决策风格;父母消极的教育方式一方面通过树立不合理的消费价值观助长中学生非理性的决策风格,另一方面通过减弱合理的消费价值观来减弱其合理的决策风格。结论：中学生消费价值观在家庭理财教育方式与消费决策风格之间起中介作用。     

特殊教育师范生感知班级氛围对学习投入的影响:专业认同的中介作用与未来取向的调节作用

探讨特殊教育师范生感知班级氛围与学习投入的关系,考察专业认同在两者之间的中介作用,以及未来取向的调节作用。采用学生感知班级氛围量表、学习投入量表、大学生专业认同量表和未来取向问卷对582名特殊教育师范生进行调查。结果发现：（1）特殊教育师范生感知班级氛围对学习投入具有正向预测作用;（2）专业认同在感知班级氛围与学习投入的关系中起着重要的中介作用;（3）未来取向显著调节特殊教育师范生感知班级氛围对学习投入的直接路径,也调节中介效应的后半段即特殊教育师范生专业认同对学习投入的影响。本研究结果丰富了特殊教育职前教育理论,对提升特殊教育师范生培养质量具有实践意义。     

Enhancing spatial skills of preschoolers from under-resourced backgrounds: A comparison of digital app vs. concrete materials

Spatial skills support STEM learning and achievement. However, children from low-socioeconomic (SES) backgrounds typically lag behind their middle- and high-SES peers. We asked whether a digital educational app—designed to mirror an already successful, spatial assembly training program using concrete materials—would be as effective for facilitating spatial skills in under-resourced preschoolers as the concrete materials. Three-year-olds (N = 61) from under-resourced backgrounds were randomly assigned to a business-as-usual control group or to receive 5 weeks of spatial training using either concrete, tangible materials or a digital app on a tablet. The spatial puzzles used were an extension of items from the Test of Spatial Assembly (TOSA). Preschoolers were pretested and posttested on new two-dimensional (2D) TOSA trials. Results indicate that both concrete and digital spatial training increased performance on the 2D-TOSA compared to the control group. The two trainings did not statistically differ from one another suggesting that educational spatial apps may be one route to providing early foundational skills to children from under-resourced backgrounds.     

Insights into the effectiveness of messaging promoting intentions to use connected vehicle technology

Connected vehicles offer considerable promise for reducing congestion, pollution, and crashes. Nonetheless, less than a third of road users are aware of the potential for connected vehicles to transform transport systems. This study examined the effectiveness of messaging aimed to increase the public’s knowledge of connected vehicle technologies using a short, animated video and its effects as assessed via a survey. Participants were assigned to either a control group, who were not exposed to the messaging, or an intervention group, who were exposed to the messaging, within a pre-post design. Participants (in the intervention group) answered questions about their knowledge of and experience with connected vehicle technologies prior to seeing the messaging and again following being exposed to such messaging together with their intentions to use these technologies in the future. As a theoretically informed investigation, the Theory of Planned Behaviour (TPB) constructs of attitudes, subjective norms, and perceived behavioural control were also measured. The results showed that the messaging increased knowledge about and intention to use connected vehicle technologies. Furthermore, changes in how the TPB constructs predicted intentions were found between the control and intervention groups which may help to explain how the messaging influenced participants’ intentions to use such technology in the future.
