The application of science to technology

The notion that technology is the application of science to the making of artefacts is a widely-held, persistent and influential view. Considerable scholarly work has been done during the past quarter century to refute it on the grounds that it is historically and ontologically inaccurate. It is a view which fails to recognise the contribution of non-scientific factors to technological development,which neglects the reverse contribution of technology to science, and which offers a superficial account of the process of application. This paper focusses on this last point, and argues that in those cases where science is applied to technology, the application process is usually exceedingly complex. The process involves the selection of appropriate knowledge, the adoption of differing criteria and the translation and re-shaping of knowledge to make it amenable to the technologist. The issue has important implications for the school curriculum. Specializations: science/technology education, technology teacher education, educational evaluation.     

Evaluation of an extra-curricular school sport programme promoting lifestyle and lifetime activity for adolescents

Abstract

The purpose of this study was to evaluate the impact of an extra-curricular school sport programme to promote physical activity among adolescents. One hundred and sixteen students (mean age 14.2 years, s = 0.5) were assigned to an intervention (n = 50) or comparison group (n = 66). The 8-week intervention involved structured exercise activities and information sessions. Four days of pedometer monitoring and time spent in non-organized physical activity and sedentary behaviours were measured at baseline and post-test. At baseline, participants were classified using steps per day as low-active (girls <11,000, boys <13,000) or active (girls ≥ 11,000, boys ≥ 13,000) and the effects of the intervention were assessed using these subgroups. Adolescents in the intervention group classified as low-active at baseline increased their step counts across the 8-week intervention (baseline: 7716 steps/day, s = 1751; post-test: 10,301 steps/day, s = 4410; P < 0.05) and accumulated significantly more steps (P < 0.05) than their peers in the comparison group (baseline: 8414 steps/day, s = 2460; post-test: 8248 steps/day, s = 3674; P = 0.879). The results of the present study provide further evidence that physical activity monitoring using pedometers is an effective strategy for increasing activity among low-active adolescents.     

Potential moderators of day-to-day variability in children’s physical activity patterns

Little is known about whether physical activity compensation occurs and, if so, what are potential moderators of such responses. This study examined whether children’s physical activity, sedentary time and energy expenditure on one day was associated with these behaviours the following day, and what factors may moderate observed associations. One hundred and twenty-seven children (8–11 years) wore an ActiGraph accelerometer for eight days. Time spent in sedentary time and physical activity was obtained. Daily energy expenditure was also assessed using a SenseWear Armband (n=98). Moderators examined were sex, age, BMI, fitness, and fundamental movement skills (FMS). Multilevel analyses were conducted using generalized mixed models. On any given day, every additional 10 minutes spent in moderate-to-vigorous physical activity (MVPA) was associated with 9.3 minutes less MVPA the following day. Every additional 10kcal expended on one day was associated with 2.9 fewer kcal expended the following day. Additional time spent sedentary on any given day was associated with less light physical activity the following day in children with lower FMS. The results are largely consistent with the compensation hypothesis, with children appearing to compensate their activity between days. Strategies to minimise potential compensatory changes may be needed for children overall rather than for specific population sub-groups.     

A systematic review of strength and conditioning programmes designed to improve fitness characteristics in golfers

It has been suggested that conditioning programmes have the potential to improve golf performance through fitness adaptations. The primary aim of this systematic review was to evaluate the effectiveness of conditioning programmes on measures of golf-related fitness and golf performance. Four electronic library databases were searched and the quality of the studies was assessed using criteria adapted from the Consolidated Standard of Reporting Trials statement. Thirteen studies satisfied our criteria for inclusion. Nine studies involved middle-aged to older male recreational golfers and four studies used younger more skilled golfers. Conditioning programmes involved the use of machine weights, free weights, medicine balls, and elastic bands, and most studies included a flexibility component. Most studies assessed changes in fitness characteristics and generally resulted in improvements. All but two of the studies assessed changes in club head speed and reported increases. The findings from this review suggest that strength and conditioning programmes can have a positive effect on the golf swing and fitness characteristics of golfers. The majority of studies in this review evaluated the effects of generic conditioning programmes on fitness characteristics and club head speed. Future studies should investigate the effects of more golf-specific strength and conditioning programmes to improve fitness and overall golf performance.     

Issues of inclusion

Abstract

This article represents a meta-analysis of three research KEYWORDS projects undertaken recently at the National Foundation for Educational children in Research. The projects were discrete but resultant data showed that they care; had a common focus: ways in which schools do or might accommo-disaffection; date more effectively the needs of a range of pupils who are at risk of inclusion; being denied the opportunity to experience the ‘normality’ of the cur-special riculum offered by schools in England and Wales. The pupils whose educational experiences were studied had special educational needs, and/or were needs ‘disaffected’, and/or were in the public care. While their circumstances were, thus, ostensibly various, analysis showed that they were underpinned by a common set of needs which, unaddressed by the education system, resulted in the exclusion of the pupils. Strategies that effectively nurtured pupils’ inclusion were found to be applicable across the client group.     

Physical education teachers’ perceptions about the effectiveness and acceptability of strategies used to increase relevance and choice for students in physical education classes

School physical education (PE) aims to develop students’ knowledge and skills for lifelong participation in physical activity (PA). Unfortunately, many PE teachers report that motivating students is a significant challenge. The purpose of this study was to explore PE teacher perceptions about the effectiveness and acceptability of three self-determination theory-based motivational strategies on students’ PA, motivation, and learning during PE lessons. Thirteen PE teachers from five schools in Western Sydney, Australia, participated in this study. We carried out semi-structured post-lesson interviews with PE teachers to gather information about the perceived effectiveness and acceptability of the three intervention strategies and whether these were sustainable teaching methods: (1) explaining relevance; (2) providing choice; and (3) complete free choice. Analysis of interview data revealed that teachers believed each strategy successfully enhanced student PA, enjoyment, motivation, and student learning. The findings also showed that our motivational teaching strategies were acceptable when embedded within certain PE contexts. Overall, the results have implications for future pre-service and in-service PE teaching practice.     

Students' learning in science lessons: towards understanding the learning process

Constructivist views of learning have been applied to science education largely as a response to attempts to understand the origins of students' misconceptions in science, and therefore the learning process. As part of this effort to understand learning in science lessons, Appleton (1989) proposed a learning model drawn mainly from Piagetian (1978) ideas and generative learning theory (Osborne & Wittrock, 1983). This paper explores the development and evolution of the learning model as other constructivist view were applied, and as the model was tested against students' responses in science lessons. The revised model finally arrived at is then examined. It was found to be a useful means of describing student's learning processes during a science lesson.

Associations between fundamental movement skill competence,physical activity and psycho-social determinants in Hong Kong Chinese children

Associations between fundamental movement skills (FMS), perceived competence, enjoyment and physical activity (PA) have not been widely investigated among Chinese school children. We hypothesised that FMS would be directly related to self-reported and objectively measured PA, and indirectly related to these outcomes via perceived physical and movement skill competence, and enjoyment. Participants were 763 primary school children (age = 9.3 ± 1.7 years; 474 girls) across grades. FMS were measured for a subsample (n = 603) using Test of Gross Motor Development-2. PA using accelerometers was obtained from this subgroup (n = 238). All participating children completed a questionnaire measuring their PA participation, enjoyment, and perceived physical and movement skill competence. Structural equation modelling revealed positive associations between locomotor skills and perceived movement skill competence (β = .11, 95% CI [.001, .22]), and between perceived movement skill competence and objectively measured PA (β = .59, 95% CI [.04, 1.14]). Perceived physical competence and enjoyment mediated the association between locomotor skills and self-reported PA (β = .08, 95% CI [.02, .12]), but not objectively measured PA. Given inconsistent findings for subjective and objective measures of PA, further mediation analyses of the association between FMS and PA may be warranted.
