Purpose: There is currently no standardized testing protocol for assessing clients’ fitness/health within the Australian fitness industry. This study examined the perceptions of the feasibility of using a standardized testing protocol among Australian fitness industry professionals. Method: In 2014, 1,206 registered fitness industry professionals (aged 17–69 years) completed an online survey. Perceived feasibility for using a standardized testing protocol was assessed based on responses to 6 items. Respondents were classified as having a high level of perceived feasibility if they reported all 6 items to be “definitely feasible.” A multivariate logistic regression analysis, adjusting for demographic and fitness industry-related factors (e.g., qualification/years of experience), assessed the likelihood of having a high level of perceived feasibility. Results: Overall, 25.5% (95% CI [23.1%, 28.0%]) of the sample perceived the use of a standardized testing protocol as highly feasible. Items ranked most often as “definitely feasible” were “undertaking training to use the protocol” (55%) and “conducting follow-up testing every 6 to 12 weeks” (52%). After adjustment for the effect of confounding factors, casually employed professionals (OR = 0.63; 95% CI [0.45, 0.90]) and group instructors (OR = 0.58; 95% CI [0.41, 0.82]) were less likely to perceive standardized testing protocols as highly feasible. Conclusions: Among a large sample of Australian fitness industry professionals, slightly more than a quarter perceived using a standardized testing protocol to be highly feasible. Group instructors and casual employees perceived lower feasibility. Further research should determine the barriers to implementing a standardized testing protocol across the fitness industry.  相似文献   

Investigating Strategies for Pre-Class Content Learning in a Flipped Classroom     

Jamie L. Jensen  Emily A. Holt  Jacob B. Sowards  T. Heath Ogden  Richard E. West 《Journal of Science Education and Technology》2018,27(6):523-535

In a flipped classroom model, learning of basic content is shifted before class while in-class time is used for concept application. Empirical and controlled research studies are lacking on the best strategies to provide the necessary pre-class content instruction. In this study, we tested three methods of pre-class content learning—interactive online tutorials, video lectures, and textbook-style readings—while holding the content and the in-class application activities constant. Identical introductory, non-majors biology classes were manipulated at both a public, open-enrollment institution and a private, highly selective institution. We found that video lectures offer a small advantage to overall student learning over interactive tutorials or textbook-style readings. Although our two populations differed in their ability to effectively learn from pre-class activities, through a student-centered flipped classroom approach, students at both institutions demonstrated equal learning gains by the final assessment. Potential reasons for some observed differences are suggested.  相似文献   

Student‐Generated Pre‐Exam Questions is an Effective Tool for Participatory Learning: A Case Study from Ecology of Waterborne Pathogens Course          下载免费PDF全文

This multiyear study helps elucidate how the instructional practice of student‐generated questions support learning in a blended classroom in science, technology, engineering, and mathematics subjects. Students designed multiple‐choice pre‐exam questions aimed at higher levels of learning, according to Bloom's taxonomy. Student‐generated questions were edited by the instructor and then discussed by the students in the classroom and in an online forum. We tested the hypothesis that this intervention improves student learning, measured as student achievement on the exam following the intervention, and compared to student achievement on the traditional exam (prior to which a review session focused on instructor‐led recitation of the key concepts). Following the intervention in all years, average grade on the post‐intervention exam increased by 7.44%. It is important to point out that not all students benefited equally from this activity. Students who were in the 4th quintile (60% to 80%) based on the results of the 1st exam demonstrated the highest achievement improving their performance on average by 12.37% percentage points (measured as a score on the 2nd exam). Gains were not observed in the semesters when the intervention was not implemented. In this study we provided students detailed instructions on how to design questions that focus on testing higher levels of learning.  相似文献

Heart rate prescribed walking training improves cardiorespiratory fitness but not glycaemic control in people with type 2 diabetes     

Richard D. Morton  Daniel J. West  Jeffrey W. Stephens  Stephen C. Bain  Richard M. Bracken 《Journal of sports sciences》2013,31(1):93-99

Abstract

In this study, we examined the effects of a supervised, heart rate intensity prescribed walking training programme on cardiorespiratory fitness and glycaemic control in people with type 2 diabetes mellitus. After receiving local ethics approval, 27 individuals (21 males, 6 females) with type 2 diabetes were randomly assigned to an experimental (“walking”) or control group. Participants completed a Balke-Ware test to determine peak heart rate, peak oxygen consumption ([Vdot]O_2peak), and peak gradient. The walking group then completed a 7-week (four sessions a week) supervised, heart rate prescribed walking training programme, whereas the control group continued daily life. After training, participants completed another Balke-Ware test. Fasting blood glucose and glycosylated haemoglobin were measured at rest. The results showed that walking training elicited 80% (s = 2) of peak heart rate and a rating of perceived exertion of 11 (s = 1). Peak heart rate and [Vdot]O_2peak were higher in the walking than in the control group after training (P < 0.05). Based on the peak gradient before training, the respiratory exchange ratio was significantly lower (P < 0.05) and there was a strong trend for [Vdot]O₂ (P = 0.09) and heart rate (P = 0.09) to be lower after training at the same gradient in the walking compared with the control group. These improvements increased walking peak gradient by 5 min (s = 4 min) compared with the control (P < 0.05). There was no change in fasting blood glucose or glycosylated haemoglobin after training. Despite no change in glycaemic control, heart rate prescribed walking improved peak and sub-maximal cardiorespiratory responses. The beneficial adaptations support the use of heart rate monitoring during walking in people with type 2 diabetes mellitus.  相似文献   

The categorisation of swimming start performance with reference to force generation on the main block and footrest components of the Omega OSB11 start blocks

Abstract

Work presented in this paper provides a methodology for categorising swimming start performance based on peak force production on the main block and footrest components of the Omega OSB11 starting block. A total of 46 elite British swimmers were tested, producing over 1000 start trials. Overwater cameras were synchronised to a specifically designed start block that allowed the measurement of force production via two sets of four, tri-axis, force transducers; one set in the main block and one in the footrest. Data were then analysed, segregating trials for gender. Each start was categorised, with respect to the peak force production in horizontal and vertical components, into one of nine categories. Three performance indicators, i.e. block time, take-off velocity and distance of entry, were used to assess whether differences in performance could be correlated with these categories. Results from these data suggest that swimmers generating higher than average peak forces were more likely to produce a better overall start performance than those who produced forces lower than the average, for this population of athletes.  相似文献   

The Influence of Teacher Expectations about Twice-Exceptional Students on the Use of High Quality Gifted Curriculum: A Case Study Approach     

Tracy C. Missett  Amy Price Azano  Carolyn M. Callahan  Kimberly Landrum 《Exceptionality》2016,24(1):18-31

Twice-exceptional students show evidence of high academic performance or potential and also have a disability that impedes their ability to learn. Twice-exceptional students remain under-represented in gifted programs, and some researchers attribute such under-representation to the negative beliefs and low expectations about twice-exceptional students held by teachers. While researchers have begun to investigate the curricular models and instructional strategies that are effective for twice-exceptional students, little research addresses how teacher beliefs and expectations about student ability are reflected in the ways teachers implement such models and strategies for twice-exceptional students in gifted classrooms. Even less research addresses gifted students with emotional and behavioral disabilities. We used a case study of a third-grade teacher using a structured, model-based language arts curriculum to better understand how her expectations about a gifted student with an emotional disability influenced her instructional choices. Using observational and interview data, the case study approach allowed the researchers to personalize the experiences of this teacher and provided a context in which to examine the subtleties of teacher expectations when teaching a gifted student with an emotional disability. Implications for educational practice, particularly the need for comprehensive school-based support systems for students with emotional disabilities, are discussed.  相似文献   

Dimensions of academic interest among undergraduate students: passion,confidence, aspiration and self-expression     

Jihyun Lee  Tracy L. Durksen 《教育心理学》2018,38(2):120-138

We investigated psychological dimensions of academic interest among undergraduate students (N = 325) using a global academic interest scale. The scale was administered together with measures of academic performance, educational aspiration, career planning, goal setting, life satisfaction, attitudes towards leisure, personality and value. Exploratory factor analyses revealed four dimensions of academic interest: passion for learning, confidence in the future, career aspiration and self-expression. All four dimensions were significantly related to career planning, goal setting and life satisfaction. On the other hand, specific pairings of significant relationships were found between different dimensions of academic interest and personality and value, suggesting that students with different personalities and different sets of values are likely to appreciate and respond to different aspects of academic interest. We conclude with implications for research on academic interest development across a more diverse range of age groups.  相似文献
