Validity and repeatability of a depth camera-based surface imaging system for thigh volume measurement     

Alice M Bullas  Simon Choppin  Ben Heller 《Journal of sports sciences》2016,34(20):1998-2004

Complex anthropometrics such as area and volume, can identify changes in body size and shape that are not detectable with traditional anthropometrics of lengths, breadths, skinfolds and girths. However, taking these complex with manual techniques (tape measurement and water displacement) is often unsuitable. Three-dimensional (3D) surface imaging systems are quick and accurate alternatives to manual techniques but their use is restricted by cost, complexity and limited access. We have developed a novel low-cost, accessible and portable 3D surface imaging system based on consumer depth cameras. The aim of this study was to determine the validity and repeatability of the system in the measurement of thigh volume. The thigh volumes of 36 participants were measured with the depth camera system and a high precision commercially available 3D surface imaging system (3dMD). The depth camera system used within this study is highly repeatable (technical error of measurement (TEM) of <1.0% intra-calibration and ~2.0% inter-calibration) but systematically overestimates (~6%) thigh volume when compared to the 3dMD system. This suggests poor agreement yet a close relationship, which once corrected can yield a usable thigh volume measurement.  相似文献

The development of an instrument to measure teachers’ inquiry habit of mind     

Karel Kreijns  Marjan Vermeulen  Arnoud Evers  Celeste Meijs 《欧洲师范教育杂志》2019,42(3):280-296

In the present study the construct inquiry of mind explored and an instrument to measure it is proposed. Using three different samples, explorative and confirmative factor analyses were performed, resulting in three empirical dimensions that correspond to the three theoretical dimensions: 1) ‘value deep understanding,’ 2) ‘reserve judgment and tolerate ambiguity,’ and 3) ‘taking a range of perspectives and posing increasingly focused questions.’ Our findings suggest the teachers’ inquiry habit of mind scale has good psychometric properties making it useful not only for research that investigates teachers’ research attitude and intention to do research but also as an evaluation tool for the development of an inquiry habit of mind in both student teachers and teacher educators (in teacher education) as well as in experienced teachers (participating in professional development).  相似文献   

Refining success and dropout in massive open online courses based on the intention–behavior gap     

Maartje A. Henderikx  Karel Kreijns  Marco Kalz 《Distance Education》2017,38(3):353-368

In this paper we present an alternative typology for determining success and dropout in massive open online courses (MOOCs). This typology takes the perspectives of MOOC-takers into account and is based on the their intentions and subsequent behaviour. An explorative study using two MOOCs was carried out to test the applicability of the typology. Following the traditional approach based on course completion to identify educational success, success rates were 6.5 and 5.6%. The success rates from the perspectives of the MOOC-taker were 59 and 70%. These findings demonstrate that merely looking at course completion as a measure for success does not suffice in the context of MOOCs. This change in addressing MOOC success and dropout provides an alternative view and demonstrates the importance of MOOC-takers’ perspectives.  相似文献   

THE ROLE OF CREATIVITY IN EXPLAINING GIFTEDNESS AND EXCEPTIONAL ACHIEVEMENT     

Kurt A. Heller 《High Ability Studies》1995,6(1):7-26

In addition to exceptional cognitive abilities and domain‐specific aptitudes, creativity potentials are frequently used to explain high achievement in science and technology. In the Guilford tradition, research focuses increasingly on convergent versus divergent thinking, that is, a suspected dichotomy between intelligence and creativity. Despite important insights about the relationship of ability and creativity, a number of important questions remain unanswered. These relate not only to conceptualization and measurement problems regarding the hypothetical construct “creativity”, but also to its diagnosis and nurturance in childhood and adolescence. It would appear that, in view of current research paradigms, the roles of ability and creativity need to be redefined in order to predict and explain excellent achievements more reliably. Advances are mostly expected from synthetic approaches. Consequently new theoretical models and empirical research results will be presented. Finally, some consequences for the explanation of high ability as well as excellent performances in school, university, and at work will be discussed  相似文献   

Factors influencing the pursuit of personal learning goals in MOOCs     

Maartje Henderikx  Karel Kreijns  Jonatan Castaño Muñoz  Marco Kalz 《Distance Education》2019,40(2):187-204

MOOCs are promising opportunities for lifelong learning, but as promising as these learning opportunities seem, many learners do not succeed in pursuing their personal learning goals. Barriers to learning are the main reason for not finishing the intended (parts of the) MOOCs. This study addressed the question whether the factors age, gender, educational level, and online learning experience affect barriers faced while learning in MOOCs. The results show that it is challenging to combine work and family life with lifelong (online) learning activities, especially for learners in their early adulthood and mid-life. However, more experience with online learning positively affects individuals’ ability to cope with these challenges. Also, learners with a lower educational level may experience a lack of knowledge or difficulties with the course content. These findings may serve as input to inform potentially vulnerable learners about these issues and support them in successfully achieving their personal learning goals.  相似文献   

Shifting The Burden: Public and Private Financing of Higher Education in the United States and Implications for Europe   总被引：2，自引：0，他引：2  

Donald E. Heller  Kimberly R. Rogers 《Tertiary Education and Management》2006,12(2):91-117

Over the last two decades, there has been a significant change in the financing of higher education in the United States. A decrease in student and institutional support in real terms, tuition increases at all types of institutions, along with the view that students are the primary beneficiaries of higher education has resulted in policies that reduce the proportion of higher education costs borne by the federal and state governments. This paper will describe this financing shift in the United States, and analyse its impact on college participation with a particular focus on equity and opportunity. It will also provide an analysis of some questions that European countries should address as they implement their own policies that shift the burden of paying for college from the government to individuals, and as they consider various forms of financial assistance to help students pay for college.  相似文献   

THE NATURE AND DEVELOPMENT OF GIFTEDNESS: A LONGITUDINAL STUDY     

Kurt A. Heller 《High Ability Studies》1991,2(2):174-188

Following a short discussion of conceptual and theoretical problems of giftedness, the methodological foundations and selected results of a (presently) four year longitudinal study are presented. This study is based on a multidimensional concept of giftedness: intelligence, creativity, social competence, musical ability, psychomotor ability (or practical intelligence). Both academic achievements and leisure activities, as well as cognitive and motivational personality factors and school and family socialisation conditions relevant to giftedness, were studied. During the second project phase developmental aspects and achievement analyses of gifted and normal students aged 6 to 18 years were the central aspects of the study. Finally, methodological problems in the identification of gifted children and adolescents as well as consequences for the nurturing of giftedness are discussed.  相似文献
