Applications of Augmented Reality in Informal Science Learning Sites: a Review

The importance of increasing interest in the STEM disciplines has been noted in a number of recent national reports. While many previous studies have focused on such efforts inside of the formal classroom, comparatively few have looked closely at informal learning environments. We investigate the innovative use of technology in informal learning by reviewing research on the incorporation of augmented reality (AR) at exhibit-based informal science education (ISE) settings in the literature. We report on the common STEM-focused topics that are covered by current AR applications for ISE learning, as well as the different devices used to support these applications. Additionally, we report on the prevalence of positive learning outcomes and engagement factors commonly associated with the use AR applications in informal environments. This review aims to foster continued development and implementation of AR technology in exhibit-based ISE settings by informing the community of recent findings and promoting additional rigorous research for the future.     

Philosophy with children,self-regulation and engaged participation for children with emotional-behavioural and social communication needs

This study examined the effectiveness of Community of Philosophical Inquiry (CoPI) as an inclusive pedagogical approach by which to support the communicative interaction and opportunities for collaborative dialogue for children with social, emotional and behavioural needs in two mainstream classes. There is currently no empirical work that considers children with these particular needs participating in practical philosophy, particularly in CoPI. Two groups of children, aged between nine and twelve, engaged in CoPI over a period of 10 weeks. The philosophy sessions were conducted as part of the regular class work. The results show that the children were able to engage in collaborative, philosophical dialogue with their peers without being any more disruptive than their classmates. The findings of this study lead to the assertion that it is the structure of CoPI that supported the children’s engaged participation and self-regulation and that this might usefully be considered in creating classroom activities for all children.     

International conference on sport,leisure and ergonomics

Abstract

The aim of this study was to determine the physical demands of women’s rugby union match play using time–motion analysis and heart rate (HR) response. Thirty-eight premier club level female rugby players, ages 18–34 years were videotaped and HRs monitored for a full match. Performances were coded into 12 different movement categories: 5 speeds of locomotion (standing, walking, jogging, striding, sprinting), 4 forms of intensive non-running exertion (ruck/maul/tackle, pack down, scrum, lift) and 3 discrete activities (kick, jump, open field tackle). The main results revealed that backs spend significantly more time sprinting and walking whereas forwards spend more time in intensive non-running exertion and jogging. Forwards also had a significantly higher total work frequency compared to the backs, but a higher total rest frequency compared to the backs. In terms of HR responses, forwards displayed higher mean HRs throughout the match and more time above 80% of their maximum HR than backs. In summary, women’s rugby union is characterised by intermittent bursts of high-intensity activity, where forwards and backs have similar anaerobic energy demands, but different specific match demands.     

低碳发展方案编制指南(第三部分)——制定低碳发展规划

本节介绍制定低碳发展计划常用的核心步骤。本指南侧重城市层面;同样的步骤也适用于企业、市、省和国家等层级。中国自"十一五规划"起,对改善国内能源强度定出目标,包括各经济部门的节能目标。2009年12月中国政府公布了其碳强度目标,重点放在单位GDP用能引发的二氧化碳排放量。为实现该强度目标以及"循环经济"等经济性目标,制定低碳发展规划尤其必要。     

Security considerations for the spiral development model

Security measures have been well established within the waterfall development life cycle model. However, more software projects are using the spiral development life cycle model. Software developers and project managers can easily forget about adapting security measures. The spiral model uses iterative steps that can create changes in each phase of software development process. This will challenge security to ensure the application has few flaws or vulnerabilities that could be exploited. Failure to impose the right security measures at each of these phases can open up vulnerabilities for hackers to exploit and prove costly in patching. This paper will explore areas where security can be engaged within each iteration step of the spiral development model. This way security can continue protection of the software product as it becomes ready for deployment. The paper will help organizations realize where to deploy security measures to reduce vulnerabilities in the software application.     

Specificity of a Maximal Step Exercise Test

To adhere to the principle of “exercise specificity” exercise testing should be completed using the same physical activity that is performed during exercise training. The present study was designed to assess whether aerobic step exercisers have a greater maximal oxygen consumption (max VO₂) when tested using an activity specific, maximal step exercise test (SET; arms and legs) versus a maximal running test (legs only). Female aerobic step exercisers (N=18; 20.7 ± 1.5 years) performed three maximal graded exercise tests (GXTs): 2 SETs; 1 treadmill test (TMT). The SET consisted of six 3-min progressive stages of alternate lead, basic step, basic step with biceps curls, knee raise with pull-down, repeater knee with pull-down, lateral lunge with pull-down, and side squat with shoulder presses. Stepping rate was 32 steps· min^?1 on an 8-in (20.32 cm) step for stages 1–3, and a 10-in (25.4 cm) step for stages 4–6. Submaximal and maximal heart rate (HR) and oxygen consumption (VO₂) were recorded at the end of each stage. Test–retest reliability for the first five stages of the SET ranged from .91 to .97 for HR, and from .84 to .96 for VO₂. Maximal HR was significantly greater (p =.0001) for the SET (200 ± 6.2 beats·min^?1) as compared to the TMT (193 ± 7.9 beats·min^?1). No significant difference was found for max VO₂ (42.9 ± 8.5, 41.2 ± 5.9 ml·kg^?1·min^?1, p =.14). The SET was a valid and reliable protocol for assessing responses of these aerobic step exercisers; however, max VO₂ from a TMT did not differ significantly from the SET. Conversely, max HR obtained from the criterion TMT was 7 beats·min^?1 lower than from the SET. If a training HR for step exercise (arms and legs exercise) is prescribed based on the max HR from treadmill exercise (legs only), then the training HR should be calculated from a TMT max HR that has been increased by 7 beats·min^?1 to obtain an intensity of step exercise comparable to that of running.

Differential social and political influences on girls and boys through education out of doors in the United Kingdom

The way the outdoors was used for educational purposes was determined by the need for young men to be made fit for war and service in the British Empire, the need to improve the physical health of children from industrial conurbations and the preoccupation of those in authority with the notion of adolescence as a problem, especially the anticipated fear of juvenile delinquency. In the 1950s and early 1960s, when there was a significant increase in the use of the outdoors in education, much of the provision reflected the earlier emphasis on character training and “manly” virtues. The suggestion is made that this was due, in part at least, to the role played by a number of charismatic and influential figures and to continued sensitivity to social, political and military factors.
