Teaching for creativity: towards sustainable and replicable pedagogical practice

This article explores the pedagogical significance of recent shifts in scholarly attention away from first generation and towards second generation understandings of creativity. First generation or big ‘C’ creativity locates the creative enterprise as a complex set of behaviours and ideas exhibited by an individual, while second generation or small ‘c’ creativity locates the creative enterprise in the processes and products of collaborative and purposeful activity. Second generation creativity is gaining importance for a number of reasons: its acknowledged significance as a driver in the new or digital economy; recent clarification of the notion of ‘creative capital’; the stated commitment of a growing number of universities to ‘more creativity’ as part of their declared vision for their staff and students; and, the recognition that the creative arts does not have a monopoly on creative capability. We argue that this shift allows more space for engaging with creativity as an outcome of pedagogical work in higher education. The article builds on the project of connecting ‘creative capital’ and university pedagogy that is already underway, assembling a number of principles from a wide range of scholarship, from computer modelling to social and cultural theorising. In doing so, it provides a framework for systematically orchestrating a ‘creativity-enhancing’ learning environment in higher education.

Applying Kember's Linear‐Process Model to distance education at Charles Sturt University‐Riverina

Kember's linear‐process model of drop‐out from distance education (described in detail in Distance Education 10, 2, 196‐211) has been adapted and used as the basis for a series of interviews with students studying externally at Charles Sturt University‐Riverina. Although the sample is small, many issues are raised that arc relevant for distance educators. It is concluded Kember's model provides a useful theoretical underpinning for examining not only reasons for student withdrawal but also why they continue their studies.     

Effect of cold water immersion on repeat cycling performance and thermoregulation in the heat

Abstract

To assess the effect of cold water immersion and active recovery on thermoregulation and repeat cycling performance in the heat, ten well-trained male cyclists completed five trials, each separated by one week. Each trial consisted of a 30-min exercise task, one of five 15-min recoveries (intermittent cold water immersion in 10°C, 15°C and 20°C water, continuous cold water immersion in 20°C water or active recovery), followed by 40 min passive recovery, before repeating the 30-min exercise task. Recovery strategy effectiveness was assessed via changes in total work in the second exercise task compared with that in the first. Following active recovery, a mean 4.1% (s = 1.8) less total work (P = 0.00) was completed in the second than in the first exercise task. However, no significant differences in total work were observed between any of the cold water immersion protocols. Core and skin temperature, blood lactate concentration, heart rate, rating of thermal sensation, and rating of perceived exertion were recorded. During both exercise tasks there were no significant differences in blood lactate concentration between interventions; however, following active recovery blood lactate concentration was significantly lower (P < 0.05; 2.0 ± 0.8 mmol · l^?1) compared with all cold water immersion protocols. All cold water immersion protocols were effective in reducing thermal strain and were more effective in maintaining subsequent high-intensity cycling performance than active recovery.     

Energy system contribution to 400-metre and 800-metre track running

As a wide range of values has been reported for the relative energetics of 400-m and 800-m track running events, this study aimed to quantify the respective aerobic and anaerobic energy contributions to these events during track running. Sixteen trained 400-m (11 males, 5 females) and 11 trained 800-m (9 males, 2 females) athletes participated in this study. The participants performed (on separate days) a laboratory graded exercsie test and multiple race time-trials. The relative energy system contribution was calculated by multiple methods based upon measures of race [Vdot]O₂, accumulated oxygen deficit (AOD), blood lactate and estimated phosphocreatine degradation (lactate/PCr). The aerobic/anaerobic energy system contribution (AOD method) to the 400-m event was calculated as 41/59% (male) and 45/55% (female). For the 800-m event, an increased aerobic involvement was noted with a 60/40% (male) and 70/30% (female) respective contribution. Significant (P <?0.05) negative correlations were noted between race performance and anaerobic energy system involvement (lactate/PCr) for the male 800-m and female 400-m events (r = ? 0.77 and ??0.87 respectively). These track running data compare well with previous estimates of the relative energy system contributions to the 400-m and 800-m events. Additionally, the relative importance and speed of interaction of the respective metabolic pathways has implications to training for these events.     

Energy system contribution to 1500- and 3000-metre track running

The aim of the present study was to quantify the contributions of the aerobic and anaerobic energy systems to 1500- and 3000-m track running events during all-out time-trials performed individually on a synthetic athletic track. Ten 3000-m (8 males, 2 females) and fourteen 1500-m (10 males, 4 females) trained track athletes volunteered to participate in the study. The athletes performed a graded exercise test in the laboratory and two time-trials over 1500 or 3000?m. The contributions of the energy systems were calculated by measures of race oxygen uptake, accumulated oxygen deficit (AOD), race blood lactate concentration, estimated phosphocreatine degradation and some individual muscle metabolite data. The relative aerobic energy system contribution (based on AOD measures) for the 3000?m was 86% (male) and 94% (female), while for the 1500?m it was 77% (male) and 86% (female). Estimates of anaerobic energy expenditure based on blood lactate concentrations, while not significantly different (P?>?0.05), were generally lower compared with the AOD measures. In conclusion, the results of the present study conform with some recent laboratory-based measures of energy system contributions to these events.     

Effects of rest interval during high-repetition resistance training on strength,aerobic fitness,and repeated-sprint ability

Abstract

The effect of altering the rest period on adaptations to high-repetition resistance training is not well known. Eighteen active females were matched according to leg strength and repeated-sprint ability and randomly allocated to one of two groups. One group performed resistance training with 20-s rest intervals between sets, while the other group employed 80-s rest intervals between sets. Both groups performed the same total training volume and load. Each group trained 3 days a week for 5 weeks [15- to 20-repetition maximum (RM), 2 – 5 sets]. Repeated-sprint ability (5×6-s maximal cycle sprints), 3-RM leg press strength, and anthropometry were determined before and after each training programme. There was a greater improvement in repeated-sprint ability after training with 20-s rest intervals (12.5%) than after training with 80-s rest intervals (5.4%) (P = 0.030). In contrast, there were greater improvements in strength after training with 80-s rest intervals (45.9%) than after training with 20-s rest intervals (19.6%) (P = 0.010). There were no changes in anthropometry for either group following training. These results suggest that when training volume and load are matched, despite a smaller increase in strength, 5 weeks of training with short rest periods results in greater improvements in repeated-sprint ability than the same training with long rest periods.     

Student Communities and Individualism in American Cinema

Hollywood films partially construct how Americans think about education. Recent work on the representation of schools in American cinema has highlighted the role of class difference in shaping school film genres. It has also advanced the idea that a nuanced understanding of American individualism helps to explain why the different class genres are shaped as they are. This article attempts to refine this theoretical approach by focusing on the paradox of individualism, which suggests that individualism must always be dependent on community. We examine 5 films (Rushmore 1988, The Breakfast Club 1985, Mona Lisa Smile 2003, School of Rock 2003, and Stand and Deliver 1988) and argue that, although the values of individualism are certainly celebrated, these films also show, perhaps unwittingly, that the achievements of individualism require robust student communities. We describe how student communities function in these films, what achievements they make possible, and what obstacles they face.     

Metabolic power and energy expenditure in an international men’s hockey tournament

The purpose of this study was to ascertain the typical metabolic power characteristics of elite men’s hockey, and whether changes occur within matches and throughout an international tournament. National team players (n = 16), divided into 3 positional groups (strikers, midfielders, defenders), wore Global Positioning System devices in 6 matches. Energetic (metabolic power, energy expenditure) and displacement (distance, speed, acceleration) variables were determined, and intensity was classified utilising speed, acceleration and metabolic power thresholds. Midfielder’s average metabolic power (11.8 ± 1.0 W · kg^?1) was similar to strikers (11.1 ± 1.3 W · kg^?1) and higher than defenders (10.8 ± 1.2 W · kg^?1, P = 0.001). Strikers (29.71 ± 3.39 kJ · kg^?1) expended less energy than midfielders (32.18 ± 2.67 kJ · kg^?1, P = 0.014) and defenders (33.23 ± 3.96 kJ · kg^?1, P < 0.001). Energetic variables did not change between halves or across matches. Across all positions, over 45% of energy expenditure was at high intensity (>20 W · kg^?1). International hockey matches are intense and highly intermittent; however, intensity is maintained throughout matches and over a tournament. In isolation, displacement measures underestimate the amount of high-intensity activity, whereas the integration of instantaneous speed and acceleration provides a more comprehensive assessment of the demands for variable-speed activity typically occurring in hockey matches.
