Some Attitudes Associated with Sport Participation among Junior High School Females

This paper focuses on young female participants and their self-perceptions. The findings indicate that self-perceived characteristics of ambition, competition, strength, and speed were more evident for participants than nonparticipants. However, there was no significant difference between participants and nonparticipants concerning characteristics of happiness, affection, femininity, sensitivity, gentleness, and attractiveness. The data also indicated that the young female participants have not developed a highly professionalized orientation toward competition, yet they are more likely to be concerned about playing well than are nonparticipants. The findings suggest that even by early adolescence either selectivity and/or socialization differences are emerging between female participants and nonparticipants.     

Training,stability and control

This paper presents a system-theoretic approach to the analysis of the problem of training formally relating it to the control of an abstract dynamic system, the adaption automaton of the trainee. The utility of this formulation and the possibility of basing real training strategies upon it are discussed, and it is argued that further constraints upon the automaton are both necessary, and available, in so far as the theory corresponds to practical reality. The minimal constraints generate an extended theory in which training is related to the stability of the adaption automaton. More practical constraints lead to theoretical foundations for strategies of feedback or adaptive training. Corresponding to each set of constraints a training theorem is proved which demonstrates that the constraint is adequate to lead to a simple universal training strategy.Although this paper is highly theoretical it is argued that the formal concepts introduced correspond to intuitive models of the phenomena of learning and training which are implicit in the design of many training systems. It is hoped that the formal analysis will throw new light on these implicit assumptions and help to clarify discussion of practical approaches to training, including the possibility of computer-aided instruction given on our present level of knowledge of human cognitive skills or individual students.     

Cognitive skills and literacy performance of Chinese adolescents with and without dyslexia

The present study sought to identify cognitive abilities that might distinguish Hong Kong Chinese adolescents with dyslexia and to assess how these abilities were associated with Chinese word reading, word dictation, and reading comprehension. The cognitive skills of interest were morphological awareness, visual-orthographic knowledge, rapid naming, and verbal working memory. A total of 90 junior secondary school students, 30 dyslexic, 30 chronological age controls, and 30 reading level controls was tested on a range of cognitive and literacy tasks. Dyslexic students were less competent than the control students in all cognitive and literacy measures. The regression analyses also showed that verbal working memory, rapid naming, morphological awareness, and visual-orthographic knowledge were significantly associated with literacy performance. Findings underscore the importance of these cognitive skills for Chinese literacy acquisition. Overall, this study highlights the persistent difficulties of Chinese dyslexic adolescents who seem to have multiple causes for reading and spelling difficulties.     

Student contribution in asynchronous online discussion: a review of the research and empirical exploration

The increasingly prevalent use of Internet in schools and homes has resulted in asynchronous online discussion becoming an increasingly common means to facilitate dialogue between instructors and students, as well as students and students beyond the boundaries of their physical classrooms. This article is organized into two main sections. In the first section, we review 50 empirical studies in order to identify the factors leading to limited student contribution. Limited student contribution is defined as students making few or no postings, or students exhibiting surface-level thinking or low-level knowledge construction in online discussions. We then identify the various empirically based guidelines to address the factors. In the second section, we discuss three potential guideline dilemmas that educators may encounter: (a) use of grades, (b) use of number of posting guideline, and (c) instructor-facilitation. These are guidelines where previous empirical research shows mixed results when they are implemented. Acknowledging the dilemmas is essential for educators and researchers to make informed decisions about the discussion guidelines they are considering implementing. Finally, we report two exploratory case studies on student-facilitation that we conducted. Using students as facilitators may be an alternative solution to educators who wish to avoid the instructor-facilitation guideline dilemma.     

Improving the Validity and Reliability of a Health Promotion Survey for Physical Therapists

Purpose

Physical therapists (PTs) have a unique opportunity to intervene in the area of health promotion. However, no instrument has been validated to measure PTs’ views on health promotion in physical therapy practice. The purpose of this study was to evaluate the content validity and test-retest reliability of a health promotion survey designed for PTs.

Methods

An expert panel of PTs assessed the content validity of “The Role of Health Promotion in Physical Therapy Survey” and provided suggestions for revision. Item content validity was assessed using the content validity ratio (CVR) as well as the modified kappa statistic. Therapists then participated in the test-retest reliability assessment of the revised health promotion survey, which was assessed using a weighted kappa statistic.

Results

Based on feedback from the expert panelists, significant revisions were made to the original survey. The expert panel reached at least a majority consensus agreement for all items in the revised survey and the survey-CVR improved from 0.44 to 0.66. Only one item on the revised survey had substantial test-retest agreement, with 55% of the items having moderate agreement and 43% poor agreement.

Conclusions

All items on the revised health promotion survey demonstrated at least fair validity, but few items had reasonable test-retest reliability. Further modifications should be made to strengthen the validity and improve the reliability of this survey.Key Words: health promotion, physical therapy, validity, reliability
