Physical Activity and Fitness in Children with Developmental Disorder

Introduction: Developmental coordination disorder (DCD) is a prevalent condition characterized by poor motor proficiency that interferes with a child‟s activities of daily living. Children with DCD often experience compromised health-related fitness components such as cardiorespiratory fitness (CRF). Purpose: To better understand the physical activity and fitness characteristics of children with probable DCD (pDCD), with a particular focus on CRF. Specifically: (1) to present a synopsis of current literature; (2) to determine the longitudinal trajectories of CRF; (3) to compare the submaximal CRF of children with and without pDCD. Methods: A comprehensive, systematic literature review was conducted of the recent available data on fitness and physical activity and pDCD (Chapter 2). This review provided the background for the other two studies included in this thesis. In Chapter 3, a prospective cohort design was used to assess how CRF in children with pDCD changes over time (56 months) relative to a group of typically developing controls. Using a nested-case control design, 63 subjects with pDCD and 63 matched controls from the larger sample were recruited to participate in the lab-based component of the study (Chapter 4). In this investigation CRF was examined using the oxygen cost of work (VO2) during an incremental test on a cycle ergometer. Results: The literature review showed that fitness parameters, including CRF and physical activity levels, were consistently reduced in children with pDCD. Chapter 3 demonstrated that the difference in CRF between children with pDCD and typically developing children is substantial, and that it tends to increase over time. Results from VO2 assessments showed that children with pDCD utilized more oxygen to sustain the same submaximal workloads compared to typically developing children. Conclusions: Findings from this thesis have made several important contributions to our understanding of children with pDCD. Since differences in CRF between children with and without pDCD tend to worsen over time, this adds to the argument that interventions intended to improve CRF may be appropriate for children with motor difficulties. This thesis also presented the first evidence suggesting that DCD involves higher energy expenditure, and could help explain why children with pDCD perform poorly on tasks requiring CRF.

The Future of Physical Education in Higher Education: A Delphi Investigation

Despite the profound and widespread concern for the future of higher education physical education, there has been little systematic study on the topic. This research investigated the future by utilizing a two-round interview Delphi method. Five international experts were asked to project possible, probable, preferable and undesirable futures of the academic discipline in fifteen years time; specifically in regards to issues within the undergraduate degree programs, and the research sub-disciplines. The results of quantitative descriptive statistics and qualitative content analysis reveal an ever-changing higher education environment in the postmodern information age, which presents a complicating future for the academic discipline. The experts expressed concern that some disciplinarians will be a-futuristic and unable to operationalize the vast potential of the discipline at the institutional level, by continuing to use outdated and inappropriate frameworks of a modern era gone by.

The impact of social competence between physical activity and motor performance

Objective: To identify the association of low physical activity (PA) participation in children with various motor performances (MP) and to establish the impact of social competence (SC). Methods: Sixth grade children from PHAST study at Brock University (n=1958; 50.53% males) had MP test results from Bruininks-Oseretsky Test of Motor Proficiency, Participation Questionnaire (PQ) used for PA and Harter Social Competence Scale for self-perceived SC. Comparative tests, multiple and logistic regressions were performed. Results: Significant differences in PQ measures in MP quartiles and SCs. MP and SC are independent predictors of PA (p<.05) except with SES on free play activity, making MP not significant. Lower MP increased the odds of low total PA and organized sport participation but not for free play activities (OR~1). Higher SC reduced the risk of low participation in all PA measures. Conclusions: SC improves PA participation, including free play and organized sports, despite the child’s MP.

Challenging Weight Loss: The Effectiveness of a 12 Week Weight Loss Challenge on Weight Loss, Physical Activity and Motivation

The objective of this study was to examine the effectiveness of a 12 week weight loss intervention in a commercial fitness centre on body mass index (BMI), moderate to vigorous physical activity (MVPA) and behavioural regulations consistent with Organismic Integration Theory (OIT, Deci & Ryan, 2002). The intervention group received weekly coaching sessions and bi-weekly seminars designed to increase MVPA and improve dietary intake. The results of the mixed model analyses of variance showed a significant within-subjects main effect for BMI (F = 3.57, p = .04). Changes in MVPA were not observed over time or between conditions. Changes in behavioural regulations congruent with OIT (Deci & Ryan, 2002) favoured the intervention condition. Study results indicate that 12 week weight loss challenges in commercial fitness centres may be effective to support the internalization process of exercise behavioural regulations but ineffective at producing sustainable weight loss or behavioural changes.

A Life without Gluten: Dietary Adherence, Physical Activity and Motives

The purpose of this study was to look at individuals living on a gluten-free diet (GFD), their dietary adherence, PA levels and the reasons why they engage in these lifestyle behaviours consistent with Organismic Integration Theory (Deci & Ryan, 2002). Participants (N = 202; Mage = 42.35 years, SDage = 12.43 years) completed a series of online questionnaires. GFD adherence (74.7%) across the previous week was consistent with existing literature (Dowd et al., 2013), but participant physical activity scores were higher than reported normative values (p = .00; Wilson et al., 2010). Specific motives predicted gluten-free dietary adherence (i.e., integrated and identified regulations) and PA (i.e., intrinsic and identified regulations; p < .05). Findings may be used by health professionals to inform behavioural interventions consistent with OIT (Deci & Ryan, 2002).

Christian Education and the Ethics of Authenticity

A qualitative study was undertaken to explore the concept of authenticity in Christian education. The study was situated in the context of Christian schools in Ontario. Some of these schools have experienced declining enrolment and all of these schools face the challenge of being distinctive in a secular culture. To investigate the potential of the concept of authenticity for reclaiming the vision of Christian education, interviews were conducted with 3 experienced principals of Christian schools. Data analysis yielded an emergent conceptual framework of authenticity consisting of 5 concepts: authorship, relatedness, reflection, autonomy, and excellence. Authenticity was found to be a useful tool for school analysis of both the deep structures and the surface structures within Christian schools. To offset unauthentic tendencies that can arise within these schools, this study calls for an intentional use of the lens of authenticity to expose these tendencies and revitalize core expectations. Through the narratives shared by the Christian school principals, the study also develops a picture of the role of authentic Christian education in the development of the authentic Christian person.

Étude des manifestations d’une pensée critique visée, stimulée et manifestée, chez des étudiants en formation initiale en enseignement de l’éducation physique et à la santé

L’école et les programmes de formation à l’enseignement ont connu beaucoup de transformations au cours des dernières décennies. Ces changements sont notamment associés au mouvement de la professionnalisation de l’enseignement qui met l’accent, entre autres, sur l’importance de développer une réflexivité critique chez les futurs enseignants à travers des cours théoriques et des stages. Dans cette optique, le Ministère de l’éducation, des loisirs et du sport (MELS) et les institutions universitaires ont la responsabilité d’interpréter les caractéristiques propres à une pensée critique et de les intégrer à la formation initiale des enseignants. Cependant, bien que le concept de pensée critique ait fait l’objet de nombreuses recherches théoriques et empiriques depuis les travaux sur la pensée réfléchie de Dewey, il n’existe toujours pas une définition consensuelle du concept. Néanmoins les philosophes « classiques » (Ennis, McPeck, Paul, Siegel, Lipman) s’entendent pour soutenir qu’une pensée critique présuppose un doute méthodique qui conduit à la mobilisation d’habiletés et d’attitudes intellectuelles complexes, reliées à l’évaluation des faits et des situations. De leur côté, des épistémologues issus du champ de la psychologie développementale (King & Kitchener, Kuhn, Perry, et d’autres) ont élaboré des modèles de développement d’une pensée critique basés sur l’identification de stades. L’un des plus récents modèles est issu des sciences de l’éducation (Daniel et al.) et sera utilisé comme grille pour analyser nos données. Il présuppose quatre modes de pensée (logique, métacognitif, créatif et responsable) et leur complexification à partir de trois perspectives épistémologiques (égocentrisme, relativisme et intersubjectivité). La présente étude, de nature qualitative, cherche à d’identifier la réflexivité (simple ou critique) visée par les textes officiels du MELS, stimulée par l’Université de Montréal (UdeM) dans le cadre de la formation initiale des étudiants inscrits en Éducation physique et à la santé (ÉPS) et manifestée par ces étudiants en fin de formation. Pour ce faire, nous avons eu recours à une analyse de contenu, et à une analyse basée sur le modèle développemental de Daniel et ses collègues. Ces analyses ont été conduites sur le référentiel de compétences du MELS, sur les indicateurs de compétences et les consignes de rédaction des rapports synthèses de l’UdeM, ainsi que sur des verbatim d’entrevues individuelles et de groupe et sur les rapports synthèses des participants (au nombre de neuf). Les résultats d’analyse du référentiel de compétences et des indicateurs de compétences montrent que les réflexivités visée et stimulée sont de l’ordre d’une pensée réfléchie mais pas nécessairement d’une pensée critique. Parallèlement, la réflexivité manifestée par les stagiaires lors des entrevues ainsi que dans leurs rapports synthèse s’est révélée être de l’ordre d’une pensée réfléchie pas nécessairement critique même si des manifestations d’une pensée critique ont occasionnellement pu être observées.

Health, Education and Employment in a Forward-Backward Dichotomy Based on Standard of Living Index for the Tribes in Kerala

The Paper unfolds the paradox that exists in the tribal community with respect to the development indicators and hence tries to cull out the difference in the standard of living of the tribes in a dichotomous framework, forward and backward. Four variables have been considered for ascertaining the standard of living and socio-economic conditions of the tribes. The data for the study is obtained from a primary survey in the three tribal predominant districts of Wayanad, Idukki and Palakkad. Wayanad was selected for studying six tribal communities (Paniya, Adiya, Kuruma, Kurichya, Urali and Kattunaika), Idukki for two communities (Malayarayan and Muthuvan) and Palakkad for one community (Irula). 500 samples from 9 prominent tribal communities of Kerala have been collected according to multistage proportionate random sample framework. The analysis highlights the disproportionate nature of socio-economic indicators within the tribes in Kerala owing to the failure of governmental schemes and assistances meant for their empowerment. The socio-economic variables, such as education, health, and livelihood have been augmented with SLI based on correlation analysis gives interesting inference for policy options as high educated tribal communities are positively correlated with high SLI and livelihood. Further, each of the SLI variable is decomposed using Correlation and Correspondence analysis for understanding the relative standing of the nine tribal sub communities in the three dimensional framework of high, medium and low SLI levels. Tribes with good education and employment (Malayarayan, Kuruma and Kurichya) have a better living standard and hence they can generally be termed as forward tribes whereas those with a low or poor education, employment and living standard indicators (Paniya, Adiya, Urali, Kattunaika, Muthuvans and Irula) are categorized as backward tribes

Mathematical modelling in mathematics education and instruction

This paper aims at giving a concise survey of the present state-of-the-art of mathematical modelling in mathematics education and instruction. It will consist of four parts. In part 1, some basic concepts relevant to the topic will be clarified and, in particular, mathematical modelling will be defined in a broad, comprehensive sense. Part 2 will review arguments for the inclusion of modelling in mathematics teaching at schools and universities, and identify certain schools of thought within mathematics education. Part 3 will describe the role of modelling in present mathematics curricula and in everyday teaching practice. Some obstacles for mathematical modelling in the classroom will be analysed, as well as the opportunities and risks of computer usage. In part 4, selected materials and resources for teaching mathematical modelling, developed in the last few years in America, Australia and Europe, will be presented. The examples will demonstrate many promising directions of development.

Research and teaching: a holy or an unholy alliance?

Much of the self-image of the Western university hangs on the idea that research and teaching are intimately connected. The central axiom here is that research and teaching are mutually supportive of each other. An institution lacking such a set of relationships between research and teaching falls short of what it means to be a university. This set of beliefs raises certain questions: Is it the case that the presence of such a mutually supportive set of relationships between research and teaching is a necessary condition of the fulfilment of the idea of the university? (A conceptual question). And is it true that, in practice today, such a mutually supportive set of relationships between research and teaching characterises universities? (An empirical question). In my talk, I want to explore these matters in a critical vein. I shall suggest that: a) In practice today, such a mutually supportive set of relationships between research and teaching is in jeopardy. Far from supporting each other, very often research and teaching contend against each other. Research and teaching are becoming two separate ideologies, with their own interest structures. b) Historically, the supposed tight link between research and teaching is both of recent origin and far from universally achieved in universities. Institutional separateness between research and teaching is and has been evident, both across institutions and even across departments in the same institution. c) Conceptually, research and teaching are different activities: each is complex and neither is reducible to the other. In theory, therefore, research and teaching may be said to constitute a holy alliance but in practice, we see more of an unholy alliance. If, then, in an ideal world, a positive relationship between research and teaching is still a worthwhile goal, how might it be construed and worked for? Seeing research and teaching as two discrete and unified sets of activity is now inadequate. Much better is a construal of research and teaching as themselves complexes, as intermingling pools of activity helping to form the liquid university that is emerging today. On this view, research and teaching are fluid spaces, ever on the move, taking up new shapes, and themselves dividing and reforming, as the university reworks its own destiny in modern society. On such a perspective, working out a productive relationship between research and teaching is a complex project. This is an alliance that is neither holy nor unholy. It is an uneasy alliance, with temporary accommodations and continuous new possibilities

The value of using short-format podcasts to enhance learning and teaching

This paper presents the findings of a podcasting trial held in 2007-2008 within the Faculty of Economics and Business at the University of Sydney, Australia. The trial investigates the value of using short-format podcasts to support assessment for postgraduate and undergraduate students. A multi-method approach is taken in investigating perceptions of the benefits of podcasting, incorporating surveys, focus groups and interviews. The results show that a majority of students believe they gained learning benefits from the podcasts and appreciated the flexibility of the medium to support their learning, and the lecturers felt the innovation helped diversify their pedagogical approach and support a diverse student population. Three primary conclusions are presented: (1) most students reject the mobile potential of podcasting in favour of their traditional study space at home; (2) what students and lecturers value about this podcasting design overlap; (3) the assessment-focussed, short-format podcast design may be considered a successful podcasting model. The paper finishes by identifying areas for future research on the effective use of podcasting in learning and teaching.

Relationship between physical capacity and quality of life in workers university

Aim: Examine the relationship between the functional capacity and the quality of life related to health in university workers. Methodology: Cross-sectional study in 146 subjects, divided in two groups: Low functional Capacity (< 9 METs) and High functional Capacity (> 9.1 METs). We evaluated quality of life related to health (HRQOL-Health Questionnaire SF-12) and functional capacity (Questionnaire PAR/PAF) as indicators of health status. Results: 47.3% (69 men) and 52.7% (78 women). The average age of the groups was 35.0 ± 9.7 years (range 19,0-60,0 years). For HRQOL, the average found in the population assessed was 45.2 ± 4.42 (range 33,0-58,1) and 43.8 ± 6.87 (range 19,8-43,8) in components Physical Component Summary (PCS-12) and Mental Component Summary (MCS-12), respectively p = NS. Significant differences were found when comparing functional ability and sex, p<0,001 in both groups. Similarly, sex and mental component MCS-12 (group of Lower Functional) p = 0,049 as well as women and the physical component PCS-12, p = 0,05 between groups. Finally, a better score in HRQL observed in the group of High Capacity and functional components in both sex OR 0.59 (0.25-1.38). Conclusions: The results of this study demonstrate the relationship between High functional Capacity and a better HRQOL in this population.
