Development of an Instrument to Assess Fourth and Fifth Grade Students' Attitudes Toward Physical Education

The purpose of the authors in this study was to develop an instrument to assess fourth and fifth grade students' attitudes toward physical education. The methods for validation included (a) an elicitation study and instrument question development, (b) a pilot study, and (c) a series of analyses to assess, construct, and content validity and to assess reliability. Once data for 1,344 students were collected, an iterative process was completed using principal component analysis, exploratory factor analysis, Cronbach's alpha, and confirmatory factor analysis using structure equation modeling. Data analysis showed that the instrument fit two different models. The first model shows students' attitudes to be influenced by cognition and affect. The second model shows a 4-factor model comprised of cognition- teacher, cognition-curriculum, affect- teacher, and affect-curriculum. This study yielded an instrument with valid and reliable scores that can assess elementary school students' attitudes toward physical education.     

Investigating Attitudes Toward Physical Education: Validation Across Two Instruments

The Centers for Disease Control have suggested that physical education plays a role in promoting healthy lifestyles. Prior research suggests a link between attitudes toward physical education and physical activity outside school. The current study provides additional evidence of construct validity through a validation across two instruments measuring attitudes toward physical education by investigating their psychometric properties with a sample of 6th grade students (N = 377). Confirmatory factor analysis results indicate that the four-factor model fit the data well for both instruments based on fit indices, and a multitrait-multimethod analysis provides evidence of convergent and discriminant validity. Cross validation of these instruments permits longitudinal investigations on the role of attitudes toward physical education and their impact on physical activity.     

Teachers' perceptions of in-service teacher training to support curriculum change in physical education: The Hong Kong experience

The purpose of this study was to evaluate the effectiveness of an in-service training program and understand teachers' receptivity to curriculum change in physical education. A total of 183 primary school teachers were recruited as participants on a voluntary basis. They were asked to respond to a questionnaire about their receptivity to changes in the current physical education curriculum as well as their views on the effectiveness of a teacher development program that was organized by the Chinese University of Hong Kong. The results showed that the participants felt that in-service training was needed to equip them to implement a physical education program in line with the curriculum reform. The in-service training program was deemed to be practical and effective, bringing about good communication among school teachers, educational experts, and government curriculum officers. In terms of their receptivity to curriculum change, the participants generally had positive attitudes to the innovation and showed further support for the change after attending the program. The role of the principal and the need for school support for the reform are discussed in the concluding section.     

Clinically Meaningful Change Estimates for the Six-Minute Walk Test and Daily Activity in Individuals With Chronic Heart Failure

Purpose

The purpose of the present pilot study was to provide a preliminary estimate of the minimum detectable difference (MDD) and minimum clinically important difference (MCID) of the six-minute walk test (6MWT) and daily activity in outpatients with chronic heart failure (CHF).

Methods

A convenience sample of 22 adults with stable New York Heart Association Functional Class II and III CHF performed two baseline 6MWTs separated by 30 minutes of rest. Subjects then wore a triaxial accelerometer for 7 days to monitor daily activity. After 7 weeks of usual care, subjects again wore the accelerometer for 7 days and then returned to the clinic to complete the Global Rating of Change Scale (GRS) with regard to their heart disease and perform another set of 6MWTs. For the 6MWT, the MDD was calculated using the two baseline 6MWT distances. For daily activity, the MDD was calculated using two methods: (1) day-to-day test-retest reliability during baseline monitoring, and (2) baseline to follow-up test-retest reliability in those who reported no change on the GRS. The MCID for the 6MWT and daily activity was calculated using the mean and 95% confidence interval (CI_95%) for those subjects who reported ‘improvement’ on the GRS.

Results

The MDD at the CI_95% for the 6MWT was 32.4 meters. The MCID for the 6MWT was 30.1 (CI_95% 20.8, 39.4) meters. The MDD for daily activity was 5,909 vector magnitude units (VMU·hr.⁻¹) The MCID for daily activity was 1,337 VMU·hr.⁻¹ There was good alignment of the MDD and MCID for the 6MWT, suggesting that clinically meaningful change is approximately 32 meters. However, the calculated MCID was substantially less than measurement error as represented by the MDD, indicating that the MCID was underestimated in this sample or that daily activity may be robust to change in overall disease status.Key Words: six-minute walk test, daily activity, heart failure, clinically meaningful change     

Imagery use in sport: Mediational effects for efficacy

The factors that influence whether an athlete chooses to engage in imagery are largely unknown. One reason may be the amount of confidence athletes have in their ability to image. The aim of this study was to examine the relationships among efficacy in using imagery, imagery use and imagery ability. Consistent with Bandura's (, ) theory, it was hypothesized that there would be a positive correlation between efficacy in using imagery and imagery use, and that efficacy in using imagery would mediate the relationship between imagery ability and imagery use. Participants were 74 female athletes from various sports. The instruments we used were the Movement Imagery Questionnaire?–?Revised (Hall & Martin, ) for imagery ability, the Sport Imagery Questionnaire (Hall, Mack, Paivio, & Hausenblas, ) for imagery use, and a modified version of the latter questionnaire for efficacy in using imagery. Correlations showed that the more athletes were confident in their ability to use a certain image, the more they used it. Efficacy in using imagery was found to mediate only the relationship between imagery ability and cognitive imagery use.     

Influence of ingesting a carbohydrate‐electrolyte solution on endurance capacity during intermittent,high‐intensity shuttle running

The aim of this study was to examine the effects of ingesting a carbohydrate‐electrolyte solution on endurance capacity during a prolonged intermittent, high‐intensity shuttle running test (PIHSRT). Nine trained male games players performed two exercise trials, 7 days apart. On each occasion, they completed 75 min exercise, comprising of five 15‐min periods of intermittent running, consisting of sprinting, interspersed with periods of jogging and walking (Part A), followed by intermittent running to fatigue (Part B). The subjects were randomly allocated either a 6.9% carbohydrate‐electrolyte solution (CHO) or a non‐carbohydrate placebo (CON) immediately prior to exercise (5 ml kg^‐1 body mass) and every 15 min thereafter (2 ml kg^‐1 body mass). Venous blood samples were obtained at rest, during and after each PIHSRT for the determination of glucose, lactate, plasma free fatty acid, glycerol, ammonia, and serum insulin and electrolyte concentrations. During Part B, the subjects were able to continue running longer when fed CHO (CHO = 8.9 ± 1.5 min vs CON = 6.7 ± 1.0 min; P < 0.05) (mean ± s.e.m.). These results show that drinking a carbohydrate‐electrolyte solution improves endurance running capacity during prolonged intermittent exercise.     

Wicked Wikipedia? Communities of Practice,the Production of Knowledge and Australian Sport History

Academic responses to Wikipedia since its inception in 2001 have shifted from scepticism and hostility to serious critique. Wikipedia is a project driven by a community of amateur, and sometimes professional, scholars and it is this community – and associated rules and practices – that shapes the site's publicly viewable content. Despite the centrality of egalitarianism and communal wisdom to the Wikipedian ethos, the encyclopaedia is not filled equitably with historical knowledge or topics. This article addresses the role of Wikipedia in the production of knowledge in a sport history context. An analysis of 115 Wikipedia articles written about notable Australian sportspeople revealed a disproportionately large group of high-quality cricket biographies. Further investigation revealed that a small group of Wikipedians were responsible for writing these articles. The work of this community of practice is indicative of the influence that dedicated special interest groups can have over the production of knowledge on Wikipedia and raises broader questions about the production of knowledge in sport history.     

Building a space to dream: Supporting indigenous children's survivance through community-engaged social and emotional learning

Indigenous communities practice survivance and challenge social and political systems to support their children's identity and well-being. Grounded in transformative social-emotional learning (SEL) and tribal critical race theory, this 3-year community-based participatory research study (2019–2021) examined how a SEL program co-created with an Indigenous community in Flathead Nation in Montana supports anti-racism and anti-colonialism among Indigenous children. Critical reflexivity and thematic analyses of Community Advisory Board meetings and journals written by 60 students (M_age = 10.3, SD = 1.45; 47% girls; 60% Native American) during the SEL program revealed themes on Indigenous identity, belonging, wellness, and colonialism. These results shed light on challenging the racist and colonial roots of education to support Indigenous children's survivance and social-emotional well-being.
