The purpose of this study was to examine the following: (a) the relationships among the latent constructs of fundamental motor skills (FMS), health-related physical fitness (HRF), and observed body fatness in South Korean adolescents with mental retardation (MR); (b) the indirect effect of fundamental motor skills on body fatness when mediated by health-related fitness; and (c) whether the degree of MR and gender affects these relationships. Students ages 13 to 18 years (287 boys and 134 girls) were recruited for the study. Separate structural equation models were estimated based on gender and the level of disability: mild or moderate MR. Group differences in the model structure were not found, so the data were combined and a single model estimated. The results showed that FMS significantly contributed to HRF (standardized effects beta = .53), p < .01 and indirectly contributed to decreased body fatness mediated by HRF (-.27), p < .01. HRF directly contributed to decreased fatness (-.50), p < .01. The results from this study support the importance of both increased FMS and increased HRF in relation to decreased body fatness. 相似文献
The purpose was to evaluate the traditional method, of visually focusing on the ball, in comparison to focusing on the hole, during the putting stroke. The study design consisted of a pretest, a 4-week practice period, and a posttest. Participants (n = 31, handicap: 18.7 ± 10.4) practised using only one of the two gaze techniques. Testing consisted of having all participants putt using both gaze techniques from both a 1.22 m and a 4 m distance. Five putts were executed for each gaze technique/putt length combination for a total of 20 putts in each testing session per participant. The kinematics of every putting stroke executed during testing (1240 strokes) were captured using a TOMI? system. There was a significant improvement in putting success for both groups following practice (P = 0.001). Practising while visually focusing on the hole, resulted in a statistically significant reduction in putter speed variability in comparison to practising while visually focusing on the ball (P = 0.017). Visually focusing on the hole did not meaningfully (nor statistically) affect the quality of impact as assessed by the variability in face angle, stroke path, and impact spot at the precise moment the putter head contacted the ball. 相似文献
The common core concept was presented as the vehicle for developing a more adaptive educational program for the counseling profession. The communication model developed was based on the assumption of common elements of role behavior for counselors across agency settings. The model also depends upon the explication of communication and information needs necessary for adequate functioning of the counselor across as well as within settings as the basis for curriculum content. An organizational structure for implementing the communication model was explicated in a training program setting to facilitate the implementation of the model. 相似文献
The ability to transfer knowledge between design projects has been linked to developing expertise and, as such, is an important skill for designers. However, externalising and analysing the knowledge from the design project in ways that support transfer can be a challenge. This article explores how reflective practice can foster the conditions for knowledge transfer and links these outcomes with design expertise characteristics. A structured and critical approach to reflection was introduced alongside a graphic design project with the aim to foster the conditions for transfer to other projects. A case study strategy of inquiry was employed, drawing on a qualitative research approach, and framed by theories of reflective practice and cognitive psychology. The research demonstrates that graphic design students readily reach an ability to describe, analyse and make judgements from their design experience. However, the types of reflection that supports knowledge transfer from one design experience to another – generalisation and abstraction – are not as apparent. This outcome aligns with the behaviours associated with the expertise characteristics of a novice designer. 相似文献
Purpose: The purpose of this study was to systematically develop and validate an instrument to assess parental perceptions toward adapted physical education (APE) teachers, who work with children with autism.Methods: Participants included two expert panels and parents of children and youth with autism. The survey used a Likert-scale design where parents rated their level of satisfaction regarding communication with, qualifications of, and rapport with the APE teachers.Results: Based on α coefficients for each of the three subscales, it was concluded that the survey had high internal validity. Split-half reliability determined by the Spearman Brown Prophecy coefficient indicated high reliability.Conclusion: Preliminary evidence demonstrated that the survey may be a useful tool in assessing parental perceptions of their child's APE teacher. 相似文献
Eighty‐seven high school students participated in the study in one of four conditions:
1. Visual Organiser/Cooperative Learning
2. Cooperative Learning only
3. Visual Organiser only
4. Teacher‐Directed
Students were taught how to use mole maps to assist them in solving single‐quantity and multiple‐quantity mole problems. A mole problem involves converting quantities of chemicals to moles, a unit of measurement used in Chemistry. Students took tests immediately after instruction and then took mid‐term examinations that included mole problems. Repeated measures analyses with post‐instruction test scores and the mid‐term scores for single and multiple‐quantity mole problems showed that student performance was significantly better immediately after instruction for both kinds of problems. Students who used visual organisers and cooperative learning outperformed students who experienced teacher‐directed instruction on single‐quantity mole problems and also on the immediate post‐instruction test of multiple‐quantity mole problems. Cooperative learning resulted in less decay in performance over time. 相似文献
Abstract This article explores the tensions between the potential of computer conferencing as represented by theoretical models and its actual uses in higher education. An overview of the literature highlights major themes that run throughout this body of research, including claims that the medium: 1. provides a democratic environment due to the equal access afforded to participants; 2. enhances active learning and collaboration; 3. shifts the role of the teacher from classroom leader to facilitator of learning; and 4. encourages more thoughtful participation due to the text-based, asynchronous nature of interaction. Against this backdrop, case studies of courses taught through The New School for Social Research's on-line programme provide empirical data that challenge many of these claims. A discussion of teaching practices related to student participation and perceptions of computer conferencing is also offered to serve practitioners and teacher education efforts. 相似文献
