The effects of physical activity and physical fitness on children's achievement and cognitive outcomes: a meta-analysis

It is common knowledge that physical activity leads to numerous health and psychological benefits. However; the relationship between children's physical activity and academic achievement has been debated in the literature. Some studies have found strong, positive relationships between physical activity and cognitive outcomes, while other studies have reported small, negative associations. This study was a comprehensive, quantitative synthesis of the literature, using a total of 59 studies from 1947 to 2009 for analysis. Results indicated a significant and positive effect of physical activity on children's achievement and cognitive outcomes, with aerobic exercise having the greatest effect. A number of moderator variables were also found to play a significant role in this relationship. Findings are discussed in light of improving children's academic performance and changing school-based policy.     

Explicitly Teaching Critical Thinking Skills in a History Course

Critical thinking skills are often assessed via student beliefs in non-scientific ways of thinking, (e.g, pseudoscience). Courses aimed at reducing such beliefs have been studied in the STEM fields with the most successful focusing on skeptical thinking. However, critical thinking is not unique to the sciences; it is crucial in the humanities and to historical thinking and analysis. We investigated the effects of a history course on epistemically unwarranted beliefs in two class sections. Beliefs were measured pre- and post-semester. Beliefs declined for history students compared to a control class and the effect was strongest for the honors section. This study provides evidence that a humanities education engenders critical thinking. Further, there may be individual differences in ability or preparedness in developing such skills, suggesting different foci for critical thinking coursework.     

The impact of tier 1 reading instruction on reading outcomes for students in Grades 4–12: A meta-analysis

Understanding the efficacy of evidence-based reading practices delivered in the Tier 1 (i.e. general classroom) setting is critical to successful implementation of multi-tiered systems, meeting a diverse range of student learning needs, and providing high quality reading instruction across content areas. This meta-analysis presents evidence on the effects of Tier 1 reading instruction on the reading outcomes of students in Grades 4–12, and a synthesis of effects for students identified as struggling readers. Results from this meta-analysis of 37 publications conducted between 2000 and 2015 reveal significant, positive effects for Tier 1 reading instruction on comprehension and vocabulary outcomes. A synthesis of the results for struggling readers indicates that they maintained or improved reading comprehension over struggling readers receiving typical instruction.     

“We've Got to Keep Meeting Like This”: A Pilot Study Comparing Academic Performance in Shifting-Membership Cooperative Groups Versus Stable-Membership Cooperative Groups in an Introductory-Level Lab

This study examined possible ways to increase student engagement in small sections of a large, introductory-level, required university course. Research shows that cooperative group learning boosts achievement through fostering better interpersonal relationships between students. Cooperative group learning is an evidence-based instructional practice engaging students in active learning. The present study investigated whether cooperative groups with sustained-membership functioned more effectively for boosting performance than shifting-membership cooperative groups. Findings indicated that the amount of class time spent in groups influenced the impact of shifting or sustained-membership. A significant difference in performance was found for sustained-group students when group activities were used the majority of the time during recitation.     

Voice,empowerment and youth-produced films about ‘gangs’†

This article explores the dissonance between the expansive discourses imagined by the advocates for youth media as helping foster ‘empowerment’ and ‘voice', versus the more circumscribed realities of participatory media production. I focus on a two-part case study – considering both a film-making project for ‘at risk’ young people in South London and the English national government funder that provided the resources for the young people to take part. This case study allows for an exploration of the political economy of youth media, and the relationship between youth media funding and how and why young people in my research often chose to make films about ‘gangs', a striking topic of concern across 11 youth media case study sites. I use this empirical example as a means to analyse how ‘empowerment’ in youth media projects, understood as both critical media literacy and youth voice, moves from abstract discourse to on-the-ground practice.     

Early Behavioral Inhibition and Emotion Regulation: Pathways Toward Social Competence in Middle Childhood

This study examined emotion regulation (ER) as a mediator in the relation between early behavioral inhibition (BI) and later social competence (N = 257), and whether this mediation varied depending on BI levels. Maternal report and observational measures were used to assess BI (ages 2 and 3). Children's ER strategies (age 5) and social competence with an unfamiliar peer (age 7) were measured using observational measures. Results showed that BI predicted less engaged ER strategies during a disappointment task, and engaged ER predicted higher social competence. Engaged ER mediated the effect of BI on social competence, but only for highly inhibited children. Findings elucidate developmental trajectories of risk and resilience, and suggest targeting regulatory strategies in early prevention efforts with highly inhibited children.     

Success factors impacting Latina/o persistence in higher education leading to STEM opportunities

This study investigates how Latina/Latino youth resist, conform to, and persist in schooling, and explores their preparation for an education in science, technology, engineering and math (STEM) fields. Using Latino Critical Race Theory as a framework, evidence of the “sticky mess” of racial inequalities (Espinoza and Harris in Calif Law Rev 10:499–559, 1997) and the concept of community cultural wealth (Yosso in Race Ethn Educ 8:69–91, 2005) will be used to understand how Latina/o students successfully persist in college. Quantitative and qualitative findings collected at two public universities in 2007–2012 show that Latina/o parents play a significant role in influencing their children’s decision to attend college; family, friend and community support and hard work have also been instrumental in college success. This is evident through parents’ encouragement to persist, expectations to do well and students serving as role models for siblings and peers. As policy makers in the educational arena emphasize STEM fields, there is a significant opportunity for Latino students to make valuable contributions.     

Constructivism: Defense or a Continual Critical Appraisal A Response to Gil-Pérez et al.

This commentary is a critical appraisal of Gil-Pérez et al.'s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of `normal' science; (b) Authors fail to recognize the importance of von Glasersfeld's contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement a constructivist pedagogy without a constructivist epistemology has been ignored; and (d) Failure to recognize that the metaphor of the `student as a developing scientist' facilitates teaching strategies as students are confronted with alternative/rival/conflicting ideas. Finally, we have shown that constructivism in science education is going through a process of continual critical appraisals.     

Quantum Yang-Baxter equation and constant R-matrix over Grassmann algebra

INTRODUCTION The Yang-Baxter equation(Yang,1967;Baxter,1972)is one of the most valuable concepts in modern theoretical physics(Baxter,1982).The importance of detailed study of Yang-Baxter equation solutions is due to its key role in constant solution models of sta-tistics mechanics(Baxter,1972;1982)and field the-ory in lower dimensions(Yang,1967),conformal field theory(Di Francesco et al.,1997)and in quan-tum integrable systems(Faddeev et al.,1990).From the group-theoretical viewpoint…
