The influence of live- vs. video-model presentation on the early acquisition of a new complex coordination     

Léna Lhuisset  Eric Margnes 《Physical Education & Sport Pedagogy》2015,20(5):490-502

Background: Demonstration is a widely used method in sports teaching and coaching, based on the assumption that it is more beneficial than verbal instructions or trial-and-error methods for skill acquisition. Although in teaching/coaching situations, the demonstration is usually carried out in front of the learners, in a research context, it is most often presented via a video. However, a direct comparison between these two types of model has rarely been undertaken in a motor context.

Purpose: In this study, we aimed to compare the effectiveness of the observation of a live and a videomodel for the early acquisition of a complex judo movement.

Research Design: Participants observed either a live or a videomodel executing the task. After observation, they practised for three minutes taking five trials and then performed it for analysis. This procedure was repeated three times. The form and technique of each participant's execution were evaluated using a technical score.

Main results: The results indicated a significant improvement in the task execution by the end of the practice session. However, this improvement occurred only for the video-model group between the second and third blocks of practice.

Conclusions: The video demonstration seems more effective than the live one for the early acquisition of a completely new complex coordination. This may be due to the simplification of the visual information in the former condition because of its two-dimensionality. This simplification may allow the observer to identify the more key elements that would guide him/her for the subsequent performance of the task.  相似文献

Family Income Dynamics,Early Childhood Education and Care,and Early Child Behavior Problems in Norway          下载免费PDF全文

Henrik D. Zachrisson  Eric Dearing 《Child development》2015,86(2):425-440

The sociopolitical context of Norway includes low poverty rates and universal access to subsidized and regulated Early Childhood Education and Care (ECEC). In this context, the association between family income dynamics and changes in early child behavior problems was investigated, as well as whether high‐quality ECEC buffers children from the effects of income dynamics. In a population‐based sample (N = 75,296), within‐family changes in income‐to‐needs predicted changes in externalizing and internalizing problems (from ages 18 to 36 months), particularly for lower income children. For internalizing problems, ECEC buffered the effect of income‐to‐needs changes. These findings lend further support to the potential benefits of ECEC for children from lower income families.  相似文献   

Prenatal Caloric Intake and the Development of Academic Achievement Among U.S. Children From Ages 5 to 14          下载免费PDF全文

Eric J. Connolly  Kevin M. Beaver 《Child development》2015,86(6):1738-1758

Few studies have examined the relation between maternal caloric intake during pregnancy and growth in child academic achievement while controlling for important confounding influences. Using data from the National Longitudinal Survey of Youth, the current study examined the effects of reduced prenatal caloric intake on growth in scores on the Peabody Individual Achievement Test from ages 5 to 14. While models controlling for within‐family covariates showed that prenatal caloric intake was associated with lower reading and mathematical achievement at age 5, models controlling for between‐family covariates (such as maternal IQ) and unobserved familial confounders revealed only a statistically significant association between siblings differentially exposed to prenatal caloric intake and mathematical achievement at age 5.  相似文献

Ten Salient Practices of Undergraduate Research Mentors: A Review of the Literature     

Jenny Olin Shanahan  Elizabeth Ackley-Holbrook  Eric Hall  Kearsley Stewart  Helen Walkington 《Mentoring & Tutoring: Partnership in Learning》2015,23(5):359-376

This paper identifies salient practices of faculty mentors of undergraduate research (UR) as indicated in the extensive literature of the past two decades on UR. The well-established benefits for students involved in UR are dependent, first and foremost, on high-quality mentoring. Mentorship is a defining feature of UR. As more and different types of colleges and universities strive to meet student demand for authentic scholarly experiences, it is imperative to identify what effective UR mentors do in order to ensure student engagement, quality enhancement, retention, and degree-completion. We offer an original analysis of the literature on UR mentoring in which we identify 10 significant “lessons learned,” or evidence-based practices of effective UR mentors that apply broadly across disciplines, students, institutions, and mentoring approaches.  相似文献   

Adult outcomes of sustained high-quality early child care and education: Do they vary by family income?     

Andres S. Bustamante  Eric Dearing  Henrik Daae Zachrisson  Deborah Lowe Vandell 《Child development》2022,93(2):502-523

Experimental research demonstrates sustained high-quality early care and education (ECE) can mitigate the consequences of poverty into adulthood. However, the long-term effects of community-based ECE are less known. Using the 1991 NICHD Study of Early Child Care and Youth Development (n = 994; 49.7% female; 73.6% White, 10.6% African American, 5.6% Latino, 10.2% Other), results show that ECE was associated with reduced disparities between low- and higher-income children's educational attainment and wages at age 26. Disparities in college graduation were reduced the more months that low-income children spent in ECE (d = .19). For wages, disparities were reduced when children from low-income families attended sustained high-quality ECE (d = .19). Findings suggest that community-based ECE is linked to meaningful educational and life outcomes, and sustained high-quality ECE is particularly important for children from lower-income backgrounds.  相似文献
