ABSTRACT

The purpose was to identify classes of different developmental trajectories of BMI and testing them for differences in motor competence (MC) and cardiorespiratory fitness (CRF), in children and adolescents (4 to 13 years of age). This was a 5 years’ longitudinal study with six cohorts. One hundred and forty-seven children (69 girls) divided into six cohorts participated. At baseline, the youngest and the oldest cohorts had 4 and 11 years of age, respectively. Height and weight were assessed, and BMI was calculated. MC was assessed with KTK and TGMD-2, and CRF was assessed with one-mile run/walk. Developmental trajectories of BMI were identified using latent class linear-mixed modelling. Latent class membership was explained according to covariates of MC and CRF. Two meaningful classes were identified. Class 1 (78.92% of the participants) showed lower initial BMI and a lower slope compared to class 2 (21.08% of the participants) (all ps < 0.001). Class membership only predicted trajectories in motor coordination, with children in class 1 having a better development.

In conclusion, this study identified two meaningful trajectories for children based on their BMI development across five time points. In line with previous research, children with slower increasing BMI showed better motor coordination improvements.  相似文献

Visuospatial Orientation Learning through Virtual Reality for People with Severe Disability     

Alejandro de la Torre-Luque  Luis Valero-Aguayo  Ernesto J. de la Rubia-Cuestas 《International Journal of Disability, Development & Education》2017,64(4):420-435

This study aims to test how an intervention based on virtual reality (VR) may enhance visuospatial skills amongst people with disability. A quasi-experimental intra-group study was therefore conducted. Participants were 20 people with severe disability (65% males; 34.35 years, on average, and 84.95% of disability rate according to the Andalusian Government index). Intervention consisted of 15 sessions of active navigation using a VR building similar to the participants’ day rehabilitation centre with the task of locating different rooms and objects. The time spent and errors in route in the virtual and the real environments were measured before and after the intervention. Additionally, participants had to fill out a map location task. As a result, participants showed fewer errors and less time at post-intervention assessments even with non-trained stimuli (p < .05). These results demonstrate the usefulness of VR-based interventions with active navigation to accelerate orientation learning in real-life situations.  相似文献

Intercorporeality and ethical commitment: an activity perspective on classroom interaction   总被引：1，自引：0，他引：1  

Luis Radford  Wolff-Michael Roth 《Educational Studies in Mathematics》2011,77(2-3):227-245

In this article, we present a sociocultural alternative to contemporary constructivist conceptions of classroom interaction. Drawing on the work of Vygotsky and Leont??ev, we introduce an approach that offers a new perspective through which to understand the specifically human forms of knowing that emerge when people engage in joint activity. To this end, we present two concepts: space of joint action and togethering. The space of joint action allows us to capture the collective and sensuous or intercorporeal dimensions of thought and feeling in interaction. We resort to the concept of togethering to capture the ethical commitment participants make to engage in and produce activity. These concepts are illustrated through a discussion of concrete episodes from an elementary mathematics classroom.  相似文献   

A psychosocial approach to shame,embarrassment and melancholia amongst unemployed young men and their fathers     

Luis Jimenez  Valerie Walkerdine 《Gender and education》2011,23(2):185-199

This paper uses a psychosocial approach to explore young unemployed men’s resistance to work they describe as ‘embarrassing’ and ‘feminine’, in the context of the closure of a steelworks in a town in the South Wales valleys. In our psychosocial interview‐based study, with young men as well as their mothers and (where possible) their fathers, we found a community riven with complex feelings about masculinity and femininity, projected on to the young men in such a way as to almost scapegoat them. The experience of the young men was marked by embarrassment and shame. They feel bullied and shamed by their families, peers and others in the community for not being able to find gender‐appropriate work.  相似文献   

Identity Production in Figured Worlds: How some Mexican Americans become Chicana/o Activist Educators   总被引：1，自引：0，他引：1  

Luis UrrietaJr. 《The Urban Review》2007,39(2):117-144

Using Holland, Lachicotte, Skinner, and Cain’s (1998) theory of identity and their concept of figured worlds, this article provides an overview of how twenty-four Mexican Americans came to produce Chicana/o Activist Educator identities. The desire to raise consciousness (teach for social justice pero con ganas) and “give back to the [their] community” became a very important part of this identity. Using an ethnographic interview as well as a life history interview methodology, this article specifically focuses on the participants’ conceptual and procedural identity production in local Chicana/o activist figured worlds (usually in colleges and universities). In these local figured worlds, the participants produced a more complex process of identity production that was both conceptual and procedural. The article concludes with broad implications for urban teacher education. Luis Urrieta, Jr. is assistant professor of cultural studies and education and Fellow in the Lee Hage Jamail Regents Chair in Education at the University of Texas at Austin. His research interests are in identity, agency, and social movements in education with a focus on Chicana/o and Indígena (P’urhépecha) education, citizenship and social studies education. 1 University Station D5700, Austin, TX 78712, USA.  相似文献

Development and construct validation of an inventory for assessing the home environment for motor development     

Rodrigues LP  Saraiva L  Gabbard C 《Research quarterly for exercise and sport》2005,76(2):140-148

A contemporary view of early childhood motor development considers environmental influences as critical factors in optimal growth and behavior, with the home being the primary agent. However, there has been minimal research examining the relationship between motor development and the home. The present study addresses this gap with the goal of creating an innovative parental self-report instrument to assess the quality and quantity of factors (affordances and events) in the home that are conducive to enhancing motor development in children ages 18-42 months. Following initial face validity determination, expert opinion feedback and selective pilot testing, construct validity was examined using 321 Portuguese families. Factor analysis techniques were used to: (a) compare competingf actorial models according to previous theoretical assumptions, and (b) analyze the fit of the preferred model. Of the five plausible models tested, the five-factor solution provided the best fit to the data. Reliability was established through the scale reliability coefficient with a value of .85. The findings of this study suggest that the Affordances in the Home Environment for Motor Development Self-Report is a valid and reliable instrument to assess how well home environments afford movement and potentially promote motor development.  相似文献
