Being a ‘professional’ primary school teacher at the beginning of the 21st century: a comparative analysis of primary teacher professionalism in New Zealand and England     

Terry Locke  Graham Vulliamy  Rosemary Webb  Mary Hill 《教育政策杂志》2013,28(5):555-581

This article analyses findings from two studies conducted collaboratively across two educational settings, New Zealand and England, in 2001–2002. These studies examined the impact of national educational policy reforms on the nature of primary teachers’ work and sense of their own professionalism and compared these impacts across the two countries. Adopting a policy ethnography approach, using in‐depth interview data from samples of teachers in each country, it is argued that there have been discursive shifts in the meaning of the three key terms, autonomy, altruism and knowledge, embodied in the classical professionalism triangle. These shifts reflect policy‐makers’ moves from a ‘professional‐contextualist’ conception of teacher professionalism towards the ‘technocratic‐reductionist’ conception that accompanies neo‐liberal educational reforms in many countries. Teachers in both countries experienced increasing constraints on their autonomy as they became far more subject to ‘extrinsic’ accountability demands. Whether these demands were perceived as enhancing or diminishing teacher professionalism depended on the manner in which they were filtered through the profession’s defining quality, namely teachers’ altruistic concerns for the welfare of the children in their care.  相似文献   

Developing primary science through IT-INSET     

Dan Wicksteed  Mary Hill 《Education 3-13》2013,41(1):32-36

The purpose of the research study was to find out if the use of Information Communication Technology (ICT) could improve the planning, performing and evaluating process within a sequence of six gymnastics lessons, and whether this would then improve the children's technique. The research consisted of a questionnaire given to the 30 children in the class at the end of the six consecutive lessons, an interview with the class teacher prior to the implementation of ICT and again afterwards, and observations. The findings showed that ICT improved the plan, perform and evaluate stages, within gymnastics, and consequently, the children's technique improved.  相似文献

A comparative study on oxidative stress and antioxidant status in ischemic stroke patients with and without diabetes     

Benedicta D’Souza  Vivian D’Souza  S. Sowmya  G. Seema  C. N. Hemalatha  M. Anu  G. Sajana 《Indian journal of clinical biochemistry : IJCB》2008,23(3):218-222

The study was conducted to find out the extent of lipid peroxidation and antioxidant status in ischemic stroke patients (ISPs) with and without diabetes. Malondialdehyde (MDA) was studied as a marker of lipid peroxidation. Glutathione (GSH), uric acid and ceruloplasmin were estimated to study the antioxidant potential of ISPs. Significantly higher levels of MDA were found in both the groups of ISPs and the increase in MDA was more in ISPs without diabetes. GSH levels were decreased significantly in both the groups of ISPs and maximum decline was found in ISPs with diabetes. Uric acid levels were significantly increased in both the groups of ISPs. Ceruloplasmin levels were increased significantly in ISPs without diabetes, whereas its levels were slightly decreased in ISPs with diabetes. A negative correlation was found between MDA and the antioxidants GSH, uric acid and ceruloplasmin in ISPs with diabetes. This study suggests that there is an association between ischemic stroke and increased oxidative stress and the antioxidant potential is impaired in both the groups of ISPs with and without diabetes.  相似文献

Physiological responses in different intensities of resistance exercise – Critical load and the effects of aging process     

Vivian Maria Arakelian  Cássia da Luz Goulart  Renata Gonçalves Mendes  Nuno Manoel de Sousa  Renata Trimer  Solange Guizilini 《Journal of sports sciences》2019,37(12):1420-1428

Aim was to identify critical load (CL) in young and elderly apparently healthy male cohorts. To contrast the metabolic, cardiovascular and perceptual responses on CL according to age. We evaluated 12 young (23 ± 3 years) and 10 elderly (70 ± 2 years) apparently healthy active males, who underwent: (1) 1 repetition maximum (1RM) test on a 45° Leg Press; (2) on different days, three high-intensity resistance exercise constant load tests (60%, 75% and 90% 1RM) until fatigue (Tlim). Absolute values of both the CL asymptote and curvature constant (kg) were significantly lower in elderly subjects (P < 0.05). In contrast, elderly subjects demonstrated a significantly higher number of repetitions at CL when compared with young subjects (P < 0.05). As expected, oxygen uptake (VO₂) and heart rate (HR) during maximal aerobic exercise testing were significantly reduced in older subjects. However, percent-predicted aerobic capacity were higher in older subjects (P < 0.05). In addition, blood lactate ([La^?]) corrected to Tlim and rating of perceived exertion values were greater in younger subjects at all intensities (P < 0.05). These findings, despite reduced force production in older subjects, endurance-related parameters are well preserved according to age-adjusted percent-predicted values in apparently healthy males.  相似文献

Relative age and maturation selection biases in academy football     

Megan Hill  Sam Scott  Robert M Malina  Darragh McGee  Sean P Cumming 《Journal of sports sciences》2020,38(11-12):1359-1367

ABSTRACT

This study examined the simultaneous effects of relative age and biological maturity status upon player selection in an English professional soccer academy. A total of 202 players from the U9 to U16 age groups, over an eight-year period (total of 566 observations), had their relative age (birth quarter) and biological maturity (categorised as late, on-time or early maturing based upon the Khamis-Roche method of percentage of predicted adult height at time of observation) recorded. Players born in the first birth quarter of the year (54.8%) were over-represented across all age groups. A selection bias towards players advanced in maturity status for chronological age emerged in U12 players and increased with age; 0% of players in the U15 and U16 age group were categorised as late maturing. A clear maturity selection bias for early maturing players was, however, only apparent when the least conservative criterion for estimating maturity status was applied (53.8% early and 1.9% late maturing in the U16 age group). Professional football academies need to recognise relative age and maturation as independent constructs that exist and operate independently. Thus, separate strategies should perhaps be designed to address the respective selection biases, to better identify, retain and develop players.  相似文献   

Development of perfectionism in junior athletes: Examination of actual and perceived parental perfectionism     

Luke F. Olsson  Andrew P. Hill  Daniel J. Madigan  George Woodley 《Journal of sports sciences》2020,38(6):669-675

ABSTRACT

Initial research suggests that parental perfectionism is central to the development of athlete perfectionism. However, it is unclear whether perceived or actual parental perfectionism is most important. The present study aimed to address this issue in two ways. First, we re-examined the predictive ability of actual versus perceived parental perfectionism on athlete perfectionism. Second, for the first time, we tested whether perceived parental perfectionism mediated the relationship between actual parental perfectionism and athlete perfectionism. A sample of 150 junior athletes and their parents completed measures of perfectionism (perfectionistic strivings and perfectionistic concerns). Junior athletes completed two measures, one of their own perfectionism and one of perceptions of their parents’ perfectionism. Parents completed one measure of their own perfectionism. Regression analyses showed that perceived parental perfectionism predicted athlete perfectionism over and above actual parental perfectionism. Mediation analyses provided support for our proposed model. Overall, the findings suggest that both actual and perceived parental perfectionism are important in the development of perfectionism in junior athletes.  相似文献
