BackgroundDaily moderate-to-vigorous physical activity (MVPA) is vital to the physical, mental, and social well-being of children. Early restrictions during the coronavirus disease 2019 (COVID-19) pandemic included the closure of schools and physical activity (PA) amenities across the US. This study aimed to examine the impact of the pandemic on the PA and play behavior of U.S. children and to provide evidence-based recommendations to improve their PA.MethodsA cross-sectional, online, parent-reported survey was conducted of children aged 3–18 years between April and June 2020 to assess light PA and MVPA using a modified Godin Leisure-Time Exercise Questionnaire. Additional items included family/child socioeconomic demographics, child adaptability to the pandemic, and community access. The survey was shared through social media and snowball sampling distribution.ResultsAnalysis of 1310 surveys indicated child PA scores declined significantly during the pandemic (from 56.6 to 44.6, max 119, p < 0.001). Specifically, MVPA score decreased (from 46.7 to 34.7, max 98, p < 0.001) while light PA remained the same. Age-based changes were seen in the quantity, variety, and intensity of PA, with the lowest pandemic-related impact seen in preschoolers and the highest in high schoolers (–4.7 vs. –17.2, p < 0.001). Community-based peer PA decreased across all age groups.ConclusionThis study shows decreased PA levels in U.S. children, according to parent reporting, during the COVID-19 pandemic. Recommendations for community leaders, educators, and parents to improve PA in children are provided. With continued spread of COVID-19, these results and recommendations may be imperative to the physical well-being of U.S. children.  相似文献

This is a report of an action-research project undertaken in tandem with the development of a new freshman seminar in criminology and criminal justice. In the freshman seminar the goal is to teach the research, critical thinking and writing skills that are the underpinnings of scholarship and good citizenship. Utilizing a unique approach, this class focuses on resources available through the University library and is taught by a professor, two librarians and a graduate teaching assistant. We hypothesize that freshmen who experience this seminar will show improvement in critical thinking skills, and that this will contribute to greater levels of academic success. This report describes the educational innovation (seminar) in sufficient detail to make replication possible, and presents preliminary findings that indicate the seminar enhances research and writing skills, fosters ability to think critically, and has a positive influence on students’ academic careers.  相似文献

Based on the assumption that children can benefit from early childhood education, the present paper investigates if the admission to day care and the selection of the type of day care (child care centers and home day care) is socially selective. In doing so, the paper analyzes how the socioeconomic and immigrant background of families influences which type of day care is used. For children under the age of three, the social background of families does influence if a child receives day care, but this influences diminishes the older the children get. The type of day care (child care centers and home day care) did not differ according to social background. The paper closes with a discussion of the challenges and potentials for development of educating children under the age of three.  相似文献

Multiple text comprehension can greatly benefit from paying attention to sources and from using this information for evaluating text information. Previous research based on texts from the domain of history suggests that source-related strategies are acquired as part of the discipline expertise as opposed to the spontaneous use of these strategies by students just entering a field. In the present study, we compared the performance of students and scientists in the domain of psychology with regard to (a) their knowledge of publication types, (b) relevant source characteristics, (c) their use of sources for evaluating the credibility of multiple texts, and (d) their ability to judge the plausibility of argumentative statements in psychological texts. Participants worked on a battery of newly developed computerised tests with a think-aloud instruction to uncover strategies that scientists and students used when reading a text. Results showed that scientists scored higher in all of the assessed abilities and that these abilities were positively correlated with each other. Importantly, the superior performance of scientists in evaluating the credibility of multiple texts was mediated by their use of source information. Implications are discussed in terms of discipline expertise.  相似文献

The purpose of this research was to develop and test a multicausal model of the individual characteristics associated with academic success in first‐year Australian university students. This model comprised the constructs of: previous academic performance, achievement motivation, self‐regulatory learning strategies, and personality traits, with end‐of‐semester grades the dependent variable of interest. The study involved the distribution of a questionnaire, which assessed motivation, self‐regulatory learning strategies and personality traits, to 1193 students at the start of their first year at university. Students' academic records were accessed at the end of their first year of study to ascertain their first and second semester grades. This study established that previous high academic performance, use of self‐regulatory learning strategies, and being introverted and agreeable, were indicators of academic success in the first semester of university study. Achievement motivation and the personality trait of conscientiousness were indirectly related to first semester grades, through the influence they had on the students' use of self‐regulatory learning strategies. First semester grades were predictive of second semester grades. This research provides valuable information for both educators and students about the factors intrinsic to the individual that are associated with successful performance in the first year at university.  相似文献

Torture of children occurs in many different ways: children may be forcibly adopted by strangers; children may be arrested and imprisoned; they may witness torture of their parents or may be tortured in the presence of their parents; and, similarly several reports of mass executions of children are available.The Danish Medical Group under Amnesty International has investigated 88 Chilean children now living in Denmark, whose parents had been tortured. Approximately 13 of the children were abnormally anxious and approximately 13 had disturbances of sleep in the form of difficulty falling asleep accompanied by broken sleep with nightmares. Approximately 14 of the children developed secondary nocturnal enuresis. Seventeen percent of the children showed behaviour difficulties in the form of aggression while 16% became introverted and depressed and had difficulties in establishing contact with children of the same age-group.  相似文献

A causal model for understanding the complex interplay between student‐reported teacher behaviors, student self‐systems, and student engagement was tested. One hundred seventeen African American students in grades 1 through 12 completed a comprehensive questionnaire regarding teacher context, self, and engagement variables. A series of hierarchical regression analyses were conducted to test the hypothesized mediation models and to construct a path model. Most hypotheses were supported. Student self‐system variables (perceived competency and autonomy) mediated relations between teacher context (structure and autonomy support), and engagement. Contrary to predictions, however, teacher involvement exerted a strong and direct effect on student engagement even when controlling for grade level and self‐system variables. Given existing research showing that African American students are at risk for low teacher involvement and that engagement is critical for academic success, research and intervention strategies are urgently needed to promote teacher involvement with these students. © 2002 Wiley Periodicals, Inc.  相似文献
