Studies show that spatial interventions lead to improvements in mathematics. However, outcomes vary based on whether physical manipulatives (embodied action) are used during training. This study compares the effects of embodied and non-embodied spatial interventions on spatial and mathematics outcomes. The study has a randomized, controlled, pre-post, follow-up, training design (N = 182; mean age 8 years; 49% female; 83.5% White). We show that both embodied and non-embodied spatial training approaches improve spatial skills compared to control. However, we conclude that embodied spatial training using physical manipulatives leads to larger, more consistent gains in mathematics and greater depth of spatial processing than non-embodied training. These findings highlight the potential of spatial activities, particularly those that use physical materials, for improving children's mathematics skills. 相似文献

Guided by the Theory of Racial Socialization in Action (TRSA; Smith-Bynum in press), this study examined observed caregiver-provided ethnic-racial socialization in response to a school-based discriminatory dilemma. Forty-five Black and 36 Latinx caregivers (88% mothers) with low-income and their children (Mage = 11.09, SD = 0.29; 46.3% female) participated in Dallas, Texas from 2018 to 2019. Dyads responded to a hypothetical scenario in which a school counselor makes a discriminatory comment to the child. Results of a factor mixture analysis suggested that caregivers engaged in the dialogue using one of four approaches: Low-engaged, Legacy, Racial Literacy, or High-engaged. Profiles were found to differ significantly by the race/ethnicity and language of caregivers and were associated with youth’s concurrent behavioral engagement (R2 = .04). 相似文献

Sample size can be chosen to achieve a specified width in a confidence interval. The probability of obtaining a narrow width given that the confidence interval includes the population parameter is defined as the power of the confidence interval, a concept unfamiliar to many practitioners. This article shows how to utilize the Statistical Analysis System (SAS) proc power procedure to determine an appropriate sample size and achieve sufficient power for a specified confidence interval. Two examples in sport and exercise science are used to illustrate sample size determination for confidence intervals in the dependent and independent t tests. The relevant SAS code and output are provided with detailed annotations. As the use of confidence intervals becomes a more integral part of studies in sport and exercise science, the reporting and analysis of their power should be considered much like that of hypothesis tests. 相似文献

The authors focused on participation in extracurricular activities as a way of improving the educational outcomes of children with disabilities. Regarding students in the general population, adolescent involvement in extracurricular activities has been shown to have a positive association with school involvement and adolescent self-esteem, academic achievement, and adolescent development. Using the Educational Longitudinal Study dataset, the authors conducted logistic regression analyses to examine the relationship between participation in high school–sponsored extracurricular activities and postsecondary degree completion for students with disabilities. Findings show a statistically significant association between postsecondary degree completion for students with disabilities and extracurricular activity participation, including extent and type of extracurricular activity. Students with disabilities who participate in high school extracurricular activities may have increased likelihood of completing a postsecondary degree. Implications for policy, practice, and future research are discussed. 相似文献

This article examines talks given by 12 female media professionals at a Southern US university’s center on women in communication between 2013 and 2015 to identify the influence of hegemonic masculinity in industry speak about women and professionalism in the fields of journalism, advertising, and public relations. This paper applies a feminist critique of discussions about “work–life balance,” “leaning in,” “emotion,” and language about the role of technology and innovation in women’s careers, to argue that inherent in these discussions about media professionalism are traits that perpetuate binary notions of feminine–masculine traits of the workplace. As a whole, these messages fail to account for notions of intersectionality and perpetuate inequality and masculine power for future professionals. 相似文献

Trust online can be a hazardous affair; many are trustworthy, but some people use the anonymity of the web to behave very badly indeed. So how can we improve the quality of evidence for trustworthiness provided online? I focus on one of the devices we use to secure others’ trustworthiness: tracking past conduct through online reputation systems. Yet existing reputation systems face problems. I analyse these, and in the light of this develop some principles for system design, towards overcoming these challenges. In providing better evidence for trustworthiness online, so we can also encourage people actually to be trustworthy more often, which is an ethically welcome outcome. 相似文献
