During the Australian National Professional Development Program (NPDP), 1994-1996, a large action-research project, Innovative Links between Universities and Schools for Teacher Professional Development, was undertaken. The project involved a consortium of 14 Australian universities working with over 100 schools (government and non-government) across all States and the Northern Territory. It was structured around the concept of Roundtables, whereby teachers engaged in school-based projects in conjunction with an academic associate from the partner university. The role of 'academic associate' demanded a rethinking of the role of university teacher educators in relation to teacher professional development. Six 'academic associates' and two teachers from the Murdoch University Roundtable formed a collaborative research group to investigate issues arising from their work with the project. The research was a self-reflective study of the work of the participants by those participants themselves. This paper relates the insights regarding collaborative work between academics and schoolteachers that emerged from the study.  相似文献   

Making instruction and assessment responsive to diverse students' progress: group-administered dynamic assessment in teaching mathematics     

Jeltova I  Birney D  Fredine N  Jarvin L  Sternberg RJ  Grigorenko EL 《Journal of learning disabilities》2011,44(4):381-395

This study entailed a 3 (instructional intervention) × 2 (assessment-type) between-subjects experimental design employing a pretest-intervention-posttest methodology. The instructional interventions were administered between subjects in three conditions: (a) dynamic instruction, (b) triarchic or theory of successful intelligence-control instruction, and (c) standard-control instruction. The assessment-type consisted between subjects of either (a) a group-administered dynamic posttest or (b) the same group-administered posttest interspersed with a control filler activity. Performance in different mathematics content areas taught in fourth grade was investigated. In total, 1,332 students and 63 classroom teachers in 24 schools across six school districts participated in the study. The results indicate the advantages of using dynamic instruction and assessment in regular classrooms while teaching mathematics, especially when the student body is highly ethnically diverse.  相似文献   

Teacher Educators,Student Teachers and Biographical Influences: implications for teacher education     

Shirley Grundy  Elizabeth Hatton 《Asia-Pacific Journal of Teacher Education》1998,26(2):121-137

The importance of acknowledging the influence of biography in understanding teachers’ work is well established in recent literature. Drawing upon data arising from a study of teacher educators and their students, we consider the influence of biography on the work of teacher educators and student teachers. We draw comparisons between the ways in which they make connections with their demographic characteristics, their personal and educational histories and their understanding of their work. We evaluate the data against two major positions in the literature on biography and draw some implications for teacher education.  相似文献

Partial swing golf shots: scaled from full swing or independent technique?     

Samuel D. Todd  Jonathan D. Wiles  Damian A. Coleman 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(3):353-365

Abstract

During practice and competition, golfers are required to use submaximal effort to hit the ball a given distance, i.e., perform a partial shot. While the full golf swing has undergone extensive research, little has addressed partial shots and the biomechanical modifications golfers employ. This study investigates the biomechanical changes between full and partial swings, and determines if the partial swing is a scaled version of the full swing. Using a repeated measures design, 13 male golfers completed a minimum of 10 swings in the full and partial swing conditions, whilst club, ball, kinematic, and kinetic parameters were recorded. Large and statistically significant reductions in body motion (centre of pressure ellipse: 33.0%, p = 0.004, d = 2.26), combined with moderate reductions in lateral shift (25.5%, p = 0.004, d = 0.33) and smaller reductions in trunk rotation (arm to vertical at top of backswing: 14.1%, p = 0.002, d = 2.58) indicate golfers favour larger reductions in proximal measures, combined with diminished reductions as variables moved distally. Furthermore, the partial swing was not found to be a scaled version of the full swing implying a new approach to coaching practices might be considered.  相似文献   

The relationships between exercise intensity, heart rate, and blood pressure during an incremental isometric exercise test   总被引：1，自引：0，他引：1

Currently, it is not possible to prescribe isometric exercise at an intensity that corresponds to given heart rates or systolic blood pressures. This might be useful in optimizing the effects of isometric exercise training. Therefore, the aim of this study was to explore the relationships between isometric exercise intensity and both heart rate and systolic blood pressure during repeated incremental isometric exercise tests. Fifteen participants performed seated isometric double-leg knee extension, during which maximum voluntary contraction (MVC) was assessed, using an isokinetic dynamometer. From this, a corresponding peak electromyographic activity (EMG(peak)) was determined. Subsequently, participants performed two incremental isometric exercise tests (at least 48 h apart) at 10, 15, 20, 25, and 30% EMG(peak), during which steady-state heart rate and systolic blood pressure were recorded. In all participants, there were linear relationships between %EMG(peak) and heart rate (r at least 0.91; P < 0.05) and between %EMG(peak) and systolic blood pressure (r at least 0.92; P < 0.05). Also, when repeated tests were compared, there were no differences in the slopes (P > 0.50) or elevations (P > 0.10) for either of the relationships. Therefore, these linear relationships could be used to identify isometric exercise training intensities that correspond to precise heart rates or systolic blood pressures. Training performed in this way might provide greater insight into the underlying mechanisms for the cardiovascular adaptations that are known to occur as a result.  相似文献   

The effects of fatigue on decision making and shooting skill performance in water polo players   总被引：1，自引：1，他引：0

The aim of this study was to assess the effects of fatigue on decision making and goal shooting skill in water polo. Fourteen junior elite male players (age 17.2 +/- 0.5 years; mass 84.2 +/- 7.6 kg; height 1.85 +/- 0.05 m) completed four sets of eight repetitions of an approximately 18 s maximal water polo specific drill. Progressively declining rest ratios for each successive set of the drill were employed to induce increasing fatigue and reflect the demands of match-play. A video-based temporally occluded decision-making task (verbalized response to various tactical situations) or goal shooting skill test (qualitative and quantitative analysis of goal shooting) was performed after each set. Heart rate, rating of perceived exertion (RPE) and blood lactate concentration were recorded. Heart rate (159 +/- 12, 168 +/- 13, 176 +/- 12, 181 +/- 12 Deats min-1; P < 0.001) and RPE (13.1 +/- 2.2, 15.5 +/- 1.7, 17.3 +/- 1.6, 19.1 +/- 1.1; P < 0.001) increased with declining rest ratios. At very high fatigue, decision-making accuracy was 18.0 +/- 21.8% better than at low fatigue (P = 0.008). Shooting accuracy and velocity were unaffected by incremental fatigue; however, skill proficiency (technique) decreased by 43 +/- 24% between the pre-test and high-fatigue conditions (P < 0.001). In conclusion, incremental increases in fatigue differentially influenced decision making (improved) relative to the technical performance (declined), accuracy and speed of the ball (unchanged) of a water polo goal shot.  相似文献   

Morphological changes of the lateral abdominal muscles in adolescent soccer players with low back pain: A prospective cohort study     

Pawel Linek  Pardis Noormohammadpour  Mohammad Ali Mansournia  Tomasz Wolny  Damian Sikora 《运动与健康科学(英文)》2020,9(6):614-619

BackgroundMost papers examining the lateral abdominal muscles (LAMs) and low back pain (LBP) are cross-sectional, with groups of participants being divided into a control and an LBP group. We hypothesized that morphological measurements of the LAMs in adolescent soccer players may predict future LBP incidence. The aim of this study was to examine the associations between the morphology of LAMs and LBP incidence rate among adolescent soccer players.MethodsNinety-seven adolescent male soccer players with no LBP at baseline were recruited into the prospective cohort study. The thickness of the LAMs was measured at baseline by ultrasound imaging in a supine rest position. Nine cases of LBP occurred during the follow-up 6-month observation.ResultsAn obliquus internus (OI) asymmetry was related to increasing LBP risk (odds ratio = 19.99; 95%CI: 2.4–167.9). Spearman correlation also showed a linear relationship between OI asymmetry value and duration of LBP (R = 0.75, p = 0.02). An OI side-to-side difference greater than 1.25 mm suggests possible LBP incidence in the 6-month observation among adolescent soccer players.ConclusionThe morphological changes of the OI may be related to LBP’s incidence in adolescent soccer players. The presence of OI asymmetry increases the odds of LBP by at least 2.4 times. Hypertrophy of the OI on one side of the body may contribute to trunk muscle imbalance.  相似文献   

Reflections on the value of autistic participation in a tri‐national teacher‐training project through discourses of acceptance,othering and power          下载免费PDF全文

Rebecca Wood  Damian Milton 《British Journal of Special Education》2018,45(2):157-171

The Transform Autism Education (TAE) project is a tri‐national teacher training scheme involving Greece, Italy and the UK, whose purpose is to set up training projects to facilitate the educational inclusion of autistic children. Running over three years from 2014 to 2017, the involvement of autistic participants has been the source of some discussion. Here, TAE team members Wood and Milton reflect on narratives of participation, acceptance and struggle which emerged during a workshop they ran in Greece. Derived from 11 non‐autistic and two autistic participants, and analysed via discourse analysis, these stories suggest a high value placed on autistic participation by non‐autistic TAE team members, but an unwitting tendency to ‘other’ autistic people and a lack of awareness of the power differential. Meanwhile, as the autistic team members describe how educational and social participation can be achieved, the implications for autism education researchers and practitioners are discussed.  相似文献   

Lactate accumulation following isometric exercise training and its relationship with reduced resting blood pressure     

Devereux GR  Coleman D  Wiles JD  Swaine I 《Journal of sports sciences》2012,30(11):1141-1148

The purpose of this study was (a) to assess lactate accumulation during isometric exercise, and to quantify the shifts in accumulation following isometric training; and (b) to relate any training-induced changes in lactate accumulation to reductions in resting blood pressure. Eleven male participants undertook isometric training for a 4-week period using bilateral-leg exercise. Training caused reductions in systolic, diastolic, and mean arterial resting blood pressure (of -4.9 ± 6.3 mmHg, P = 0.01; -2.6 ± 3.0 mmHg, P = 0.01; and -2.6 ± 2.3 mmHg, P = 0.001 respectively; mean ± s). These were accompanied by changes in muscle activity, taken as electromyographic activity to reach a given lactate concentration (from 114 ± 22 to 131 ± 27 mV and from 136 ± 25 to 155 ± 34 mV for 3 and 4 mmol · L(-1) respectively. Training intensity expressed relative to peak lactate was correlated with reduced resting systolic and mean arterial blood pressure. Training caused significant shifts in lactate accumulation, and reductions in resting blood pressure are strongly related to training intensity, when expressed relative to pre-training peak lactate. This suggests that higher levels of local muscle anaerobiosis may promote the training-induced reductions in resting blood pressure.  相似文献
