Self-efficacy is an important motivational construct for primary school teachers (teachers of children aged 5–12 years) within Australia. Teacher self-efficacy beliefs will determine the level of teacher confidence and competence to engage with a task. In this study, we explore engagement with digital technology and the associated learning and teaching of digital technology. Exploring the teacher self-efficacy beliefs towards technology of pre-service teachers, this study surveyed pre-service teachers studying to become primary teachers in two states within Australia (Victoria and Queensland). Findings are important as they provide insights into current levels of perceived competence and confidence towards engaging with digital technology as a future teacher. Findings highlight vast difference across a variety of teacher skills and actions. Given that beliefs are resistant to change after the beginning phase of teaching, it is important to understand the current beliefs of pre-service teachers who will soon be present in Australian classrooms. 相似文献

We describe the physiological characteristics of amateur outrigger canoe paddlers. Twenty-one paddlers (13 males, 8 females) were evaluated for body stature, aerobic power, muscular strength and endurance, peak paddle force, flexibility and 250 m sprint paddle performance at the end of the outrigging season. The mean variables ( - s) for the males were: age 27 - 9 years, height 175 - 5 cm, body mass 80 - 5 kg, arm span 178 - 7 cm, sitting height 100 - 2 cm, aerobic power 3.0 - 0.4 l·min-1, maximum bench press strength 85 - 19 kg, right peak paddle force 382 - 66 N and left peak paddle force 369 - 69 N. For the females, these were: age 26 - 6 years, height 168 - 5 cm, body mass 70 - 8 kg, arm span 170 - 5 cm, sitting height 97 - 3 cm, aerobic power 2.3 - 0.5 l· min-1, maximum bench press strength 47 - 10 kg, right peak paddle force 252 - 63 N and left peak paddle force 257 - 60 N. Analysis of variance revealed diff erences (P ? 0.05) between the dominant and non-dominant sides of the body for peak paddle force, isokinetic internal and external rotation, and flexion and extension torque of the shoulder joint. The outrigger canoe paddlers were generally within the range of scores found to describe participants of other water craft sports. Outrigger canoeists should be concerned with the muscular strength imbalances associated with paddling technique. 相似文献

ABSTRACT The aim of this pilot study was to evaluate the impact of a novel coach development intervention (MASTER) on coaching practices of football coaches. The study involved six coaches (of 10–12 year old) from one representative football club (Australia February–July 2017). The 15-week multi-component intervention included a face-to-face workshop, ongoing mentoring, modelled training sessions, peer assessments and group discussions. MASTER is underpinned by positive coaching and game-based coaching practices and aimed to educate coaches on how to implement and operationalise a number of evidence-based coaching elements. At each of baseline and immediate post-intervention coaches were filmed three times and evaluated using a modified version of the Coach Analysis Intervention System. Using linear mixed model analysis, significant changes were observed for time spent performing playing-form activities [+15.4% (95% CI 6.01–24.79)(t(15) = 3.5, P = 0.003], with significant changes in the type of interventions undertaken and the nature of feedback given to athletes. Program feasibility was examined using measures of recruitment, retention, adherence and satisfaction. Results indicate program feasibility and high coach evaluation ratings. MASTER demonstrated effectiveness for improving coaching practices of football coaches during training sessions. Further large-scale trials will build evidence for the utility of MASTER for guiding coaching practices in football and other sporting codes. 相似文献

The main aim of this study was to determine the test-retest reliability of existing tests of health-related fitness. Participants (mean age 14.8 years, s?=?0.4) were 42 boys and 26 girls who completed the study assessments on two occasions separated by one week. The following tests were conducted: bioelectrical impedance analysis (BIA) to calculate percent body fat, leg dynamometer, 90° push-up, 7-stage sit-up, and wall squat tests. Intra-class correlation (ICC), paired samples t-tests, and typical error expressed as a coefficient of variation were calculated. The mean percent body fat intra-class correlation coefficient was similar for boys (ICC?=?0.95) and girls (ICC?=?0.93), but the mean coefficient of variation was considerably higher for boys than girls (22.2% vs. 12.2%). The boys' coefficients of variation for the tests of muscular fitness ranged from 9.0% for the leg dynamometer test to 26.5% for the timed wall squat test. The girls' coefficients of variation ranged from 17.1% for the sit-up test to 21.4% for the push-up test. Although the BIA machine produced reliable estimates of percent body fat, the tests of muscular fitness resulted in high systematic error, suggesting that these measures may require an extensive familiarization phase before the results can be considered reliable. 相似文献
