Abstract

Aerobically fit children outperform less fit peers on cognitive control challenges that involve inhibition, cognitive flexibility, and working memory. The aim of this study was to determine whether, compared with less fit children, more fit 9- and 10-year-old pre-adolescents exhibit superior performance on a modified compatible and incompatible flanker task of cognitive control at the initial time of fitness testing and approximately one year later. We found that more fit children demonstrated increased flanker accuracy at both test sessions, coupled with a superior ability to flexibly allocate strategies during task conditions that required different amounts of cognitive control, relative to less fit children. More fit children also gained a speed benefit at follow-up testing. Structural MRI data were also collected to investigate the relationship between basal ganglia volume and task performance. Bilateral putamen volumes of the dorsal striatum and globus pallidus volumes predicted flanker performance at initial and follow-up testing one year later. The present findings suggest that childhood aerobic fitness and basal ganglia volumes relate to cognitive control at the time of fitness testing and may play a role in cognitive performance in the future. We hope that this research will encourage public health and educational changes that will promote a physically active lifestyle in children.  相似文献

A snapchat story: how black girls develop strategies for critical resistance in school     

Lauren Leigh Kelly 《Learning, Media and Technology》2018,43(4):374-389

ABSTRACT

Drawing from Black, feminist epistemologies as well as theories of critical consciousness, and adolescent digital literacies, this paper analyzes the narratives of 7 Black, female high school students who experience oppressive practices, including racial microaggressions, silencing, harsh discipline, and marginalization within a predominately White school environment. At this juncture in which race, politics, and activism intersect with school, media, and identity, this study discusses how Black, female students resist oppression and use digital and social media as well as other available tools to speak out against injustice and heighten the racial awareness of their school community. This qualitative case study uses individual and focus group interviews to examine the ways in which Black female students develop critical resistance strategies, working individually and collectively within existing structures to fight for their humanity and liberation.  相似文献   

Defining and navigating ‘action’ in a Participatory Action Research project     

Batsheva Guy  Tziporah Feldman  Caroline Cain  Lauren Leesman  Chara Hood 《Educational Action Research》2020,28(1):142-153

ABSTRACT

While the ‘action’ portion of a Participatory Action Research (PAR) project is a crucial component of the process, action tends to be challenging to define, achieve, and measure. The current paper both defines and describes action within the context of a particular PAR collaboration and explores the process and challenges of navigating and implementing action in a PAR project. The specific PAR project detailed in this paper was executed within a higher education setting and involves a group of undergraduate women co-researchers studying their experiences in STEM (Science, Technology, Engineering, and Mathematics) fields.  相似文献

Parental support of numeracy during a cooking activity with four-year-olds     

Maureen Vandermaas-Peeler  Erin Boomgarden  Lauren Finn  Caroline Pittard 《International Journal of Early Years Education》2012,20(1):78-93

While research demonstrates the importance of numeracy-related activities performed at home for young children's mathematics achievement, few studies involve observational studies of the processes which support children's mathematical learning at home. On this premise, this study reports evidence from numeracy-related interactions between parents and their four-year-old child during cookery sessions at home. Numeracy group parents who received instructions to incorporate additional mathematics into the activity provided significantly more numeracy guidance and also created more opportunities for their children to practice advanced mathematics. Comparison group parents provided enough numeracy guidance to complete the recipe but rarely provided extensive or advanced numeracy guidance. Children in the numeracy group generated significantly more correct math responses during the activity than comparison group children, though there were no significant differences on the post-test. The findings suggest the need to raise parental awareness of opportunities to support and encourage mathematics in activities at home.  相似文献

Does Dampened Physiological Reactivity Protect Youth in Aggressive Family Environments?     

Saxbe DE  Margolin G  Spies Shapiro LA  Baucom BR 《Child development》2012,83(3):821-830

Is an attenuated physiological response to family conflict, seen in some youth exposed to early adversity, protective or problematic? A longitudinal study including 54 youth (average age 15.2 years) found that those with higher cumulative family aggression exposure showed lower cortisol output during a laboratory‐based conflict discussion with their parents, and were less likely to show the normative pattern of increased cortisol reactivity to a discussion they rated as more conflictual. Family aggression interacted with cortisol reactivity in predicting youth adjustment: Adolescents from more aggressive homes who were also more reactive to the discussion reported more posttraumatic stress symptoms and more antisocial behavior. These results suggest that attenuated reactivity may protect youth from the negative consequences associated with aggressive family environments.  相似文献   

Incorporating English Language Teaching Through Science for K-2 Teachers     

Therese Shanahan  Lauren M. Shea 《Journal of Science Teacher Education》2012,23(4):407-428

English learners are faced with the dual challenge of acquiring English while learning academic content through the medium of the new language (Lee et al. in J Res Sci Teach 45(6):726?C747, 2008; Stoddart et al. in J Res Sci Teach 39(8):664?C687, 2002) and therefore need specific accommodations to achieve in both English and the content areas. Teachers require higher quality and new forms of professional development to learn and meet the needs of their students. This study examines the impact of one professional development model that explicitly embedded language learning strategies into science inquiry lessons. It also demonstrates how teachers involved in the PD program improve their self-efficacy about language instruction embedded in content and how they interpret and implement the methodology.  相似文献
