Paired Reading: a study of process and outcome     

Sam Winter 《教育心理学》1988,8(3):135-151

A peer tutored Paired Reading (PR) project was organised involving 10 and 11 year old pupils at two primary schools. Outcome was assessed by reading age. Tutor and tutee behaviour during PR was analysed by sessional tape recordings. The study indicates that many of the tutors involved in this project failed to follow PR procedures closely, that all tutors employed reinforcement at very low rates, that many important errors were left uncorrected, and that tutors were consistent in their adherence to (or neglect of) the procedures in which they had been trained.

There appeared to be no influence of tutees’ initial reading age on either tutee or tutor behaviour during PR sessions. No aspect of either tutee or tutor behaviour during PR was associated with size of reading gain.

Mechanisms underlying the apparent effectiveness of PR (and a number of other tutoring techniques for oral reading) are discussed in the context of the apparent absence of any relationship between tutor adherence to PR and tutee reading gains.  相似文献   

A rule induction framework for the determination of representative learning design in skilled performance     

Sam Robertson  Bart Spencer  Nicole Back  Damian Farrow 《Journal of sports sciences》2019,37(11):1280-1285

Representative learning design provides a framework for the extent to which practice simulates key elements of a performance setting. Improving both the measurement and analysis of representative learning design would allow for the refinement of sports training environments that seek to replicate competition conditions and provide additional context to the evaluation of athlete performance. Using rule induction, this study aimed to develop working models for the determination of high frequency, representative events in Australian Rules football kicking. A sample of 9005 kicks from the 2015 Australian Football League season were categorised and analysed according to the following constraints: type of pressure, kick distance, possession source, time in possession, velocity and kick target. The Apriori algorithm was used to develop two models. The first consisted of 10 rules containing the most commonly occurring constraint sets occurring during the kick in AF, with support values ranging from 0.15 to 0.22. None of the rules contained more than three constraints and confidence values ranged from 0.63 to 0.84. The second model considered ineffective and effective kick outcomes and displayed 70% classification accuracy. This research provides a measurement approach to determine the degree of representativeness of sports practice and is directly applicable to various team sports.  相似文献   

Why young elite athletes fear failure: consequences of failure   总被引：1，自引：0，他引：1  

Sagar SS  Lavallee D  Spray CM 《Journal of sports sciences》2007,25(11):1171-1184

Fear of failure can have negative effects on children in achievement settings, affecting many aspects of their lives. Perceiving the consequences of failure to be aversive provides the basis for fear of failure, and the anticipation of a threatening outcome elicits fear. Problems attributed to fear of failure in achievement settings are prevalent. Sport is a popular and significant achievement domain for children and adolescents and there is a lack of research on fear of failure in sport among this age group. Therefore, the aim of the present study was to investigate fear of failure in the sport domain among young elite athletes, and to explore their perceptions of the consequences of failure. Interviews were conducted individually with nine athletes aged 14 - 17 years (5 males, 4 females). Analysis identified and organized perceived consequences of failure into themes and categories. Results revealed that the most commonly perceived aversive consequences of failure were diminished perception of self, no sense of achievement, and the emotional cost of failure. These findings are consistent with those reported in adult population, suggesting the potential for generalizing existing results to young elite athletes.  相似文献   

The use of player physical and technical skill match activity profiles to predict position in the Australian Football League draft     

Carl T. Woods  James P. Veale  Neil Collier  Sam Robertson 《Journal of sports sciences》2017,35(4):325-330

This study investigated the extent to which position in the Australian Football League (AFL) national draft is associated with individual game performance metrics. Physical/technical skill performance metrics were collated from all participants in the 2014 national under 18 (U18) championships (18 games) drafted into the AFL (n = 65; 17.8 ± 0.5 y); 232 observations. Players were subdivided into draft position (ranked 1–65) and then draft round (1–4). Here, earlier draft selection (i.e., closer to 1) reflects a more desirable player. Microtechnology and a commercial provider facilitated the quantification of individual game performance metrics (n = 16). Linear mixed models were fitted to data, modelling the extent to which draft position was associated with these metrics. Draft position in the first/second round was negatively associated with “contested possessions” and “contested marks”, respectively. Physical performance metrics were positively associated with draft position in these rounds. Correlations weakened for the third/fourth rounds. Contested possessions/marks were associated with an earlier draft selection. Physical performance metrics were associated with a later draft selection. Recruiters change the type of U18 player they draft as the selection pool reduces. juniors with contested skill appear prioritised.  相似文献

Two- and Three-Year Achievement Results From the Memphis Restructuring Initiative     

Steven M. Ross  William L. Sanders  S. Paul Wright  Sam Stringfield  L. Weiping Wang  Marty Alberg 《School Effectiveness & School Improvement》2013,24(3):323-346

The purpose of this study was to analyze student achievement data from the first 3 years of the Memphis Restructuring Initiative (MRI). The MRI represents one of the first efforts by an urban school district to move past traditional top-down versus bottom-up reform debates by providing systemic support for outside-in/inside-out implementation and local co-construction of externally-developed reform designs in schools. Analyses of academic achievement focus on a state-of-the-art measure of value added assessments. At the end of 3 years the reforming schools had produced generally positive gains relative to locally matched control schools. Those results varied somewhat by reform type and by level of poverty in the communities being served. Based on the research methods used and the results, implications for future research and practice in educational reform are discussed.  相似文献

Lifesource XL-18 pedometer for measuring steps under controlled and free-living conditions     

Sam Liu  Dina Brooks  Scott Thomas  Gunther Eysenbach  Robert Peter Nolan 《Journal of sports sciences》2015,33(10):1001-1006

The primary aim was to examine the criterion and construct validity and test–retest reliability of the Lifesource XL-18 pedometer (A&D Medical, Toronto, ON, Canada) for measuring steps under controlled and free-living activities. The influence of body mass index, waist size and walking speed on the criterion validity of XL-18 was also explored. Forty adults (35–74 years) performed a 6-min walk test in the controlled condition, and the criterion validity of XL-18 was assessed by comparing it to steps counted manually. Thirty-five adults participated in the free-living condition and the construct validity of XL-18 was assessed by comparing it to Yamax SW-200 (YAMAX Health & Sports, Inc., San Antonio, TX, USA). During the controlled condition, XL-18 did not significantly differ from criterion (P > 0.05) and no systematic error was found using Bland–Altman analysis. The accuracy of XL-18 decreased with slower walking speed (P = 0.001). During the free-living condition, Bland–Altman analysis revealed that XL-18 overestimated daily steps by 327 ± 118 than Yamax (P = 0.004). However, the absolute percent error (APE) (6.5 ± 0.58%) was still within an acceptable range. XL-18 did not differ statistically between pant pockets. XL-18 is suitable for measuring steps in controlled and free-living conditions. However, caution may be required when interpreting the steps recorded under slower speeds and free-living conditions.  相似文献
