The aim of the present study was to examine the factorial validity of the Test of Performance Strategies (TOPS; Thomas et al., ) among adolescent athletes using confirmatory factor analysis. The TOPS was designed to assess eight psychological strategies used in competition (i.e. activation, automaticity, emotional control, goal-setting, imagery, negative thinking, relaxation and self-talk,) and eight used in practice (the same strategies except negative thinking is replaced by attentional control). National-level athletes (n?=?584) completed the 64-item TOPS during training camps. Fit indices provided partial support for the overall measurement model for the competition items (robust comparative fit index?=?0.92, Tucker-Lewis index?=?0.88, root mean square error of approximation?=?0.05) but minimal support for the training items (robust comparative fit index?=?0.86, Tucker-Lewis index?=?0.81, root mean square error of approximation?=?0.06). For the competition items, the automaticity, goal-setting, relaxation and self-talk scales showed good fit, whereas the activation, emotional control, imagery and negative thinking scales did not. For the practice items, the attentional control, emotional control, goal-setting, imagery and self-talk scales showed good fit, whereas the activation, automaticity and relaxation scales did not. Overall, it appears that the factorial validity of the TOPS for use with adolescents is questionable at present and further development is required.  相似文献

Buoyancy of College Women as Predicted by Certain Anthropometric Measures     

John C. Mitchem  Elizabeth C. Lane 《Research quarterly for exercise and sport》2013,84(4):1032-1036

Abstract

A discriminant analysis equation was computed to predict buoyancy from 17 anthropometric variables. The subjects for the study were 74 Caucasian women and 81 Negro women university students. The Negro group had less buoyancy and was the only group for which it was possible to compute a discriminant equation as the Caucasian group did not have any nonfloaters.  相似文献   

Team-Referent Attributions Among Sport Performers

Abstract

The aim of this study was to develop and validate a team-referent attribution scale. Conducted over three studies, Study 1 modified items from McAuley, Duncan, and Russell's (1992) Causal Dimension Scale II by rewording items to reflect team attributions and adding one item per factor. This led to the development of a 16-item scale (Causal Dimension Scale-T, CDS-T). Study 2 tested competing models of attribution theory among a sample of 433 team sport players. Confirmatory factor analysis indicated strongest support for a four-factor model (robust comparative fit index = .961; root mean squared error of approximation = .054). Study 3 tested the predictive validity of the scale among a sample of 201 team players. Results indicated that winners reported more internal and stable attributions than losers. Further, performances perceived as successful were associated with stable attributions. The results of the study, therefore, suggest that the CDS-T provides a valid measure of team-referent attributions in sport.  相似文献   

Variability in Measurement of Swimming Forces     

Rod Havriluk 《Research quarterly for exercise and sport》2013,84(2):32-39

An analysis was conducted to identify sources of true and error variance in measuring swimming drag force to draw valid conclusions about performance factor effects. Passive drag studies were grouped according to methodological differences: tow line in pool, tow line in flume, and carriage in tow tank. Active drag studies were grouped according to the theoretical basis: added and/or subtracted drag (AAS), added drag with equal power assumption (AAE), and no added drag (ANA). Data from 36 studies were examined using frequency distributions and meta-analytic procedures. It was concluded that two active methods (AAE and ANA) had sources of systematic error and that one active method (AAS) measured an effect that was different from that measured by passive methods. Consistency in drag coefficient (Cd) values across all three passive methods made it possible to determine the effects of performance factors.  相似文献

Peer assessment of oral presentations: effects of student gender,university affiliation and participation in the development of assessment criteria     

A. Mark Langan  C. Philip Wheater  Emma M. Shaw  Ben J. Haines  W. Rod Cullen  Jennefer C. Boyle 《Assessment & Evaluation in Higher Education》2005,30(1):21-34

Peer assessment provides a useful mechanism to develop many positive qualities in students studying in higher education (HE). Potential influences on peer‐awarded marks include student qualities such as gender, HE background (e.g. university affiliation) and participation in the development of the assessment criteria. Many studies that have investigated peer assessment have placed great emphasis on marks from a single tutor, or very few tutors, from a single university. This study examined grades awarded by 11 tutors (affiliated with four universities) to oral presentations delivered on a residential field course by second‐year undergraduate students from two universities studying environmental or biological disciplines. Student assessors awarded marks of fairly high precision (correlating strongly with tutor grades) but averaged 5% higher than their tutors (i.e. of only moderate accuracy). Marginally higher marks (circa 1.6%) were awarded by student assessors to speakers studying at the same university. Gender influences were detected as males tended to grade other male speakers very slightly more highly than female speakers. Marks from females were unaffected by speaker gender. Students who participated in the development of the assessment criteria did not achieve higher grades for their presentations. However, when these ‘participants’ were assessing, they awarded lower marks than their peers (i.e. closer to, but not as low as, those awarded by tutors). Lower marks were also awarded during the middle of sessions, possibly resulting from factors associated with motivation and attention of speakers and markers. Overall, the potential biases in marking by naive assessors examined in this study may influence the validity of marks generated by peer assessment schemes, but the experience of this type of assessment had positive effects on those involved.  相似文献   

An Analysis of an Interactive Videodisc System for Teaching Language Skills to Deaf Students     

Carol Tomlinson‐Keasey  Rod Brawley  Barbara Peterson 《International Journal of Disability, Development & Education》1986,33(1):49-55

An interactive videodisc system designed to teach language concepts to deaf students was evaluated in a classroom trial. An experimental group of 18 students spent 60 twenty‐minute sessions over a five‐month period learning language concepts by interacting with the system while a control group of 16 students learned the same concepts in their regular classroom setting. Both groups made significant progress from pre‐ to post‐test on two criterion‐referenced testsdeveloped by project staff. Experimental students were enthusiastic about the videodisc, felt that their language skills had improved, and were anxious to continue working with the system.  相似文献   

Student teachers' subject matter knowledge within the domain of area measurement   总被引：3，自引：0，他引：3  

Annette Baturo  Rod Nason 《Educational Studies in Mathematics》1996,31(3):235-268

This paper describes a research project whose major aim was to evaluate first-year teacher education students' understanding of subject matter knowledge in the domain of area measurement. In contrast to many previous approaches to evaluating teacher education students' subject matter knowledge, the approach adopted in this study not only focused on the student teachers' substantive knowledge but also on their knowledge about the nature and discourse of mathematics, their knowledge about mathematics in society and their dispositions towards mathematics. To this end, each student was clinically interviewed whilst engaged on a set of eight tasks that were developed for the study. The development of the tasks was a major component of the study and this is described in detail. The results of the tasks are given and the paper concludes with a discussion of the findings. This discussion focuses primarily on the implications that these results have for preservice mathematics education courses.  相似文献   

The Phoenix Rising: Emergent models of instructional design     

Sonja Irlbeck  Elena Kays  Deborah Jones  Rod Sims 《Distance Education》2006,27(2):171-185

The blurring of distinctions between online and distance education in many parts of the developed world has led to reflections on the strategies and processes by which we create effective online learning environments for the distance education learner. In this article we argue that the foundational models of instructional design that typically inform the design, development, and delivery of online environments do not always support the epistemology and pedagogy that embodies the online environment. Through an analysis of current approaches to instructional design we present a case for adopting principles of emergence theory as a means to best harness the power and potential of design and development for online distance education. Using a prototype three‐phase design model that embodies emergent principles we advocate that to achieve the full potential of interaction and community networks through online communications requires a repositioning of roles and processes associated with “instructional design.”  相似文献
