In this article, we propose a model for framing the influences on variation in infant spontaneous mastery at 12 months of age. Using the perspective of our model, we discuss the differences and similarities that our work shares with that of the other authors in this Special Issue. We hope that using our model in this way can foster integration and expansion of ideas for future studies of motivation in infancy. In addition, our model provides a roadmap for the study of important variables in risk groups. Empirical examination of the wide variation in infant capabilities and maternal emotional resources in risk groups and developmental transformations across the first two years of life can highlight important touchpoints for intervention.  相似文献

Purpose: Despite the perceived importance of sleep for athletes, little is known regarding athlete sleep quality, their prevalence of daytime sleepiness or risk factors for obstructive sleep apnoea (OSA) such as snoring and witnessed apnoeic episodes. The purpose of the present study was to characterise normative sleep quality among highly trained team sport athletes.

Methodology:175 elite or highly trained rugby sevens, rugby union and cricket athletes completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Score (ESS) and Quality of Life questionnaires and an OSA risk factor screen.

Results: On average, athletes reported 7.9?±?1.3?h of sleep per night. The average PSQI score was 5.9?±?2.6, and 50% of athletes were found to be poor sleepers (PSQI?>?5). Daytime sleepiness was prevalent throughout the population (average global score of 8.5) and clinically significant (ESS score of ≥10) in 28% of athletes. OSA may be an important clinical consideration within athletic populations, as a considerable number of athletes (38%) defined themselves as snorers and 8% reported having a witnessed apnoeic episode. The relationship between self-rated sleep quality and actual PSQI score was strong (Pearson correlation of 0.4?±?0.1, 90% confidence limits).

Conclusion: These findings suggest that this cohort of team sport athletes suffer a preponderance of poor sleep quality, with associated high levels of daytime sleepiness. Athletes should receive education about how to improve sleep wake schedules, extend total sleep time and improve sleep quality.  相似文献

Research Findings: Little is known about how parents approach preschoolers' mathematics learning and how this aligns with early mathematics education research and policy. This study examined these questions by contrasting parents' approaches to early mathematics and language and by exploring key themes in parents' talk about mathematics learning and education. Consistent with current research and policy, parents reported helping preschoolers learn mathematics and attempting to connect this learning to children's interests and everyday experiences. However, parents admitted to lacking goals for and knowledge about early mathematics. In addition, compared to language, parents reported that mathematics was taught less often at home, should be emphasized less in preschools, was less interesting to preschoolers, required more direct instruction, and was less of a personal interest and strength. Practice or Policy: Parent interventions could capitalize on parents' beliefs and practices by providing parents with concrete examples of what mathematics preschoolers learn through daily activities, how to maximize children's mathematics interests, and what the similarities are between early mathematics and language. These efforts will also need to help parents overcome their mathematics anxieties and show parents why early mathematics education is important. Similar strategies could be used to help early childhood teachers improve their mathematics practice.  相似文献

Strong arguments have been made for early intervention for child problems, stating that early is more effective than later, as the brain is more malleable, and costs are lower. However, there is scant evidence from trials to support this hypothesis, which we therefore tested in two well-powered, state-of-the-art meta-analyses with complementary strengths: (a) Individual participant data (IPD) meta-analysis of European trials of Incredible Years parenting intervention (= 13, = 1696; age = 2–11); (b) Larger, trial-level robust variance estimation meta-analysis of a wider range of parenting programs (= 156, = 13,378, Mage = 2–10) for reducing disruptive behavior. Both analyses found no evidence that intervention earlier in childhood was more effective; programs targeted at a narrower age range were no more effective than general ones.  相似文献

Twelve currently popular technical communication textbooks are analyzed for their treatment and discussions of the types of writing that engineers produce. The analysis reveals a persistent bias toward humanities-based styles and genres and a failure to address the forms of argument and evidence that our science and engineering students most need to master to succeed as rhetoricians in their fields. The essay ends with recommendations and calls upon instructors to reenvision the service course in technical communication.  相似文献

The increased use of and demand for technology in early childhood education classrooms and programs creates new challenges for practicing and preservice early educators being asked to employ such technology within their teaching. Early childhood teacher education programs have struggled to meet these demands for teaching their students how to integrate such technology into their instruction with young children. Preservice teachers who do receive such training often fail to develop the skills and/or beliefs required to implement technology effectively into their own classrooms. The study reported on in this article addresses this issue by providing insight into how a sample of early childhood preservice teachers who used iPads and their apps in their coursework and high-stakes early learning field placements made sense of using these devices as teachers. Such findings illuminate instructional opportunities for teacher educators to consider as they seek to assist their students in making sense about how to implement as well as adopt appropriate and effective instructional strategies into their own classrooms.  相似文献

Family mealtimes have the potential to promote healthy child development. This observational study of 200 family mealtimes examined the relation between child health in a group of children (ages 5 to 12) with persistent asthma and 3 dimensions of mealtime interaction: Action, Behavior Control, and Communication. Percent time spent in Action and Positive Communication varied by asthma severity, child quality of life, and sociodemographic variables. Positive communication during mealtimes predicted child quality of life. Significant interactions between demographic variables and behavior control suggested that higher levels of behavior control affected child quality of life in the context of lower maternal education. Guidance is offered for practitioners and policy makers toward promoting healthy family mealtimes as a public health priority.  相似文献
