The role of spatial ability in mixed reality learning with the HoloLens

The use of mixed reality in science education has been increasing and as such it has become more important to understand how information is learned in these virtual environments. Spatial ability is important in many learning contexts, but especially in neuroanatomy education where learning the locations and spatial relationships between brain regions is paramount. It is currently unclear what role spatial ability plays in mixed reality learning environments, and whether it is different compared to traditional physical environments. To test this, a learning experiment was conducted where students learned neuroanatomy using both mixed reality and a physical plastic model of a brain (N = 27). Spatial ability was assessed and analyzed to determine its effect on performance across the two learning modalities. The results showed that spatial ability facilitated learning in mixed reality (β = 0.21, P = 0.003), but not when using a plastic model (β = 0.08, P = 0.318). A non-significant difference was observed between the modalities in terms of knowledge test performance (d = 0.39, P = 0.052); however, mixed reality was more engaging (d = 0.59, P = 0.005) and learners were more confident in the information they learned compared to using a physical model (d = 0.56, P = 0.007). Overall, these findings suggest that spatial ability is more relevant in virtual learning environments, where the ability to manipulate and interact with an object is diminished or abstracted through a virtual user interface.     

‘Build me a male role model!’ A critical exploration of the perceived qualities/characteristics of men in the early years (0–8) in England

Young boys' ‘underachievement’ and their disaffection with learning continue to dominate education agendas [Francis, B. 2006. “Stop That Sex Drive.” Times Educational Supplement 30; Peeters, J. 2007. “Including Men in Early Childhood Education: Insights from the European Experience.” NZ Research in Early Childhood Education, 10.

This paper critically explores the perceived qualities/characteristics of men who seemingly serve as ‘male role models’ by reporting on select doctoral research findings which sought to investigate the ambiguities of the male role model from the perspective of men who work in the 0–8 sector. Research participants were asked to identify the qualities/characteristics that they felt ‘male role models’ should exhibit for young boys in the early years (0–8). The qualities/characteristics identified were categorised by research participants as being ‘masculine’ (e.g. diplomatic), ‘feminine’ (e.g. caring) or ‘natural’ (meaning authentic). Whilst research evidence suggests that male role models will present a diverse range of personal and professional qualities/characteristics, it is argued that these are likely to be shaped by not only the needs and circumstances of the children that the ‘male role model’ comes into contact with, but also the expectations of others, e.g. parents/carers and staff. This paper argues that there is a real tension between those qualities/characteristics of the male role model that are created as a result of their personality/individual beliefs and those which are anticipated or enforced by others.     

Home Economics Teachers' Intentions and Engagement in Teaching Sustainable Development

Home Economics (HE) teachers can have a central role in teaching sustainable development (SD) to young adolescents through everyday household management and the promotion of personally and globally sustainable well-being. How well the teachers cope with this task is not well known. The objective of this study was to survey Finnish HE teachers' perceptions of their current practice, coping, and future intentions in terms of teaching SD. Enablers and inhibitors to carrying out this task were further investigated. Findings from this survey suggest that HE teachers have adopted sustainability at a personal level, but often lack the resources and incentives to teach it. Ways to promote cross-curricular projects and wider integration of SD into HE are discussed.     

Jingoism,Public Opinion,And The New Imperialism

This essay analyses late-Victorian understandings of the relationship between the press, imperial diplomacy, and popular enthusiasm for empire, and examines how newspapers explained their own role in the imperial rivalries of the 1890s. During imperial disputes between Britain and France (particularly the Fashoda crisis) and between Britain and the USA (the Venezuela boundary dispute) contemporaries claimed that self-interested ‘jingo’ elements of the political elite had sought to foment conflict by manipulating ‘public opinion’, but had been defeated by statesmen (who had used the press for legitimate diplomatic purposes) and by ‘the people’ (who were averse to war). This contrasted with contemporary comments about the role played by the press in provoking wars between the USA and Spain and between Britain and the Transvaal: both the press and the people seemed to succumb to an irrational popular ‘jingoism’, and to sweep statesmen along in their wake. However, this essay argues that these contemporary verdicts about the role of newspapers in focusing popular imperialism have been too easily accepted by historians. During the imperial rivalries of the 1890s the press played an important role as a medium of transnational communication, but did not push statesmen into expansionism.     

Touching practice and physical education: deconstruction of a contemporary moral panic

This paper explores the insecurities and discursive moral panics elicited by the discussion of intergenerational touch in education, and their subsequent manifestation in ‘classroom panopticism’. In a number of contexts, public hysteria has grown around the interaction between adult and child, and whether this interaction stays within the narrow parameters of a generally consensual ‘acceptability’. Crossing these boundaries carries grave consequences for those deemed to be exploiting their position and this has had significant implications for the self-identity of practitioners. This climate of preventative fear has also served to manipulate regulatory method, realigning conceptions of practitioner independence. Drawing on interviews with Physical Education teachers in English secondary schools, and applying a Foucauldian theoretical framework, with particular reference to his interpretation of panopticism, this paper investigates the conceptual transformation of contemporary education. Whilst school spaces were once representative of stability, in which roles were clearly defined, the hierarchical dynamic has changed. The teacher, who previously presided with relative professional freedom and autonomy, is now subject to myriad pressures associated with ‘appropriate’ behaviour and the avoidance of any ‘problematic’ interactional incident. Foucault's treatment of panopticism is apt here, as teachers must conduct themselves with an acceptance that they are now governed by an unpredictable yet persistent practical scrutiny.     

Hydrodynamics of undulatory underwater swimming: A review

Undulatory underwater swimming (UUS) occurs in the starts and turns of three of the four competitive swimming strokes and plays a significant role in overall swimming performance. The majority of research examining UUS is comparative in nature, dominated by studies comparing aquatic animals' undulatory locomotion with the UUS performance of humans. More recently, research directly examining human forms of UUS have been undertaken, providing further insight into the factors which influence swimming velocity and efficiency. This paper reviews studies which have examined the hydromechanical, biomechanical, and coordination aspects of UUS performance in both animals and humans. The present work provides a comprehensive evaluation of the key factors which combine to influence UUS performance examining (1) the role of end-effector frequency and body amplitudes in the production of a propulsive waveform, (2) the effects of morphology on the wavelength of the propulsive waveform and its subsequent impact on the mode of UUS adopted, and (3) the interactions of the undulatory movements to simultaneously optimise propulsive impulse whilst minimising the active drag experienced. In conclusion, the review recommends that further research is required to fully appreciate the complexity of UUS and examine how humans can further optimise performance.     

Kinematics and kinetics of the bench-press and bench-pull exercises in a strength-trained sporting population

Understanding how loading affects power production in resistance training is a key step in identifying the most optimal way of training muscular power – an essential trait in most sporting movements. Twelve elite male sailors with extensive strength-training experience participated in a comparison of kinematics and kinetics from the upper body musculature, with upper body push (bench press) and pull (bench pull) movements performed across loads of 10–100% of one repetition maximum (1RM). 1RM strength and force were shown to be greater in the bench press, while velocity and power outputs were greater for the bench pull across the range of loads. While power output was at a similar level for the two movements at a low load (10% 1RM), significantly greater power outputs were observed for the bench pull in comparison to the bench press with increased load. Power output (P _max) was maximized at higher relative loads for both mean and peak power in the bench pull (78.6 ± 5.7% and 70.4 ± 5.4% of 1RM) compared to the bench press (53.3 ± 1.7% and 49.7 ± 4.4% of 1RM). Findings can most likely be attributed to differences in muscle architecture, which may have training implications for these muscles.     

Effect of combined carbohydrate-protein ingestion on markers of recovery after simulated rugby union match-play

Abstract

In this study, we investigated the effect of ingesting carbohydrate alone or carbohydrate with protein on functional and metabolic markers of recovery from a rugby union-specific shuttle running protocol. On three occasions, at least one week apart in a counterbalanced order, nine experienced male rugby union forwards ingested placebo, carbohydrate (1.2 g · kg body mass^?1 · h^?1) or carbohydrate with protein (0.4 g · kg body mass^?1 · h^?1) before, during, and after a rugby union-specific protocol. Markers of muscle damage (creatine kinase: before, 258 ± 171 U · L^?1 vs. 24 h after, 574 ± 285 U · L^?1; myoglobin: pre, 50 ± 18 vs. immediately after, 210 ± 84 nmol · L^?1; P < 0.05) and muscle soreness (1, 2, and 3 [maximum soreness = 8] for before, immediately after, and 24 h after exercise, respectively) increased. Leg strength and repeated 6-s cycle sprint mean power were slightly reduced after exercise (93% and 95% of pre-exercise values, respectively; P < 0.05), but were almost fully recovered after 24 h (97% and 99% of pre-exercise values, respectively). There were no differences between trials for any measure. These results indicate that in experienced rugby players, the small degree of muscle damage and reduction in function induced by the exercise protocol were not attenuated by the ingestion of carbohydrate and protein.     

Crossing the Line: Sport and the Limits of Civil Rights Protest

Scholars have ably considered the extent to which sport has been, and continues to be, a force for racial progress. What has been less comprehensively explored, however, are the unique difficulties encountered by athletes who have attempted to use sport to promote civil rights activism. Black athletes, and sympathetic white teammates, have faced considerable obstacles as sportsmen who supported the civil rights struggle. Sport has restricted the ability of sportsmen to successfully engage in civil rights activism. In the belief that it has provided an example of racial progress for the rest of society, in fact, sport has resisted the civil rights movement. This article explores the difficulties faced by athletes who attempted to be part of that movement.
