A pictorial view of the physical activity socialization of young adolescents outside of school

Childhood obesity prevention has fallen short of anticipated impact. Therefore, intervention programs need to be redirected to other potential settings to increase youth physical activity. This qualitative study, using autodriven interview techniques, was conducted to identify out-of-school settings that youth perceive as important for physical activity. Sixty-six children took photographs involving their physical activity involvement. A subsample completed follow-up focus groups. Salient themes included types of physical activities related to free play, fitness, organized sports, and chores. Most photographs included multiple children of similar age and were taken outdoors. Data suggest children associate chores with physical activity and engage in fitness-related activities. In addition, friends and family, the outdoors, and importantly, the home emerged as natural intervention components that may prove useful towards decreasing the physical inactivity and obesity of youth.     

Relationship between inductive arithmetic argumentation and deductive algebraic proof

In this paper, we present a cognitive analysis of the relationship between the argumentation process leading to the construction of a conjecture and its algebraic proof in solving Calendar Algebra problems. To solve this kind of problem, students encounter two sources of potential difficulties: the shift from using arithmetic in the argumentation to using algebra in the proof and the shift from an inductive argument towards a deductive proof. Thus, the aims of this article are to describe these cognitive difficulties and to show how students overcome them. Methodologically, we compare students’ problem solving process corresponding to three problems presented in the first four lessons of a teaching experiment. The analysis and comparison between these three resolution processes is performed using Toulmin’s model.     

Behavior Breakthroughs™: Future Teachers Reflect on a Focused Game Designed to Teach ABA Techniques

This article examines the use of a focused educational game. The game, Behavior Breakthroughs™, was created to teach people that work with children with autism, appropriate behavior management techniques. A group of undergraduate, teacher education students played the game and provided feedback on their experiences.     

Energy Expenditure and Intensity of Active Video Games in Children and Adolescents

Purpose: This study aimed to compare the energy expenditure and intensity of active video games to that of treadmill walking in children and adolescents. Method: Seventy-two boys and girls (aged 8–13 years) were recruited from local public schools. Energy expenditure and heart rate were measured during rest, during 3-km/hr, 4-km/hr, and 5-km/hr walks, and during active games (Adventure, Boxing I, Boxing II, and Dance). During walking and active games, we also assessed physical activity using an accelerometer. Results: The energy expenditure of the active games Adventure, Boxing I, Boxing II, and Dance was similar to that of treadmill walking at 5 km/hr in boys and girls. Heart rate was significantly higher for the game Adventure compared with walking at 3 km/hr, 4 km/hr, and 5 km/hr and the game Dance in both genders. The heart rate of girls during the games Adventure and Dance was significantly higher compared with boys. There was a statistically significant difference (p < .05, with an effect size ranging from 0.40 to 3.54) in the counts·min^?1, measured through accelerometry, between activities. Conclusion: XBOX 360 Kinect games provide energy expenditure and physical activity of moderate intensity for both genders. The use of active video games can be an interesting alternative to increase physical activity levels.     

Latino Maternal Literacy Beliefs and Practices Mediating Socioeconomic Status and Maternal Education Effects in Predicting Child Receptive Vocabulary

Research Findings: This study investigated the association between Mexican American maternal education and socioeconomic status (SES) and child vocabulary as mediated by parental reading beliefs, home literacy environment (HLE), and parent–child shared reading frequency. As part of a larger study, maternal reports of education level, SES, HLE, and reading beliefs along with child expressive and receptive vocabulary were collected for 252 mothers and their preschool children from 2 demographically similar school districts in 1 county. Correlations were moderate and positive, with higher levels of maternal education related to family income, HLE, book availability, and children’s expressive and receptive vocabulary. Consistent with long-standing evidence, maternal education and SES were predictors of children’s vocabulary, albeit indirectly through maternal reading beliefs, HLE, and reading frequency. Practice or Policy: Findings extend current knowledge about specific pathways through which social class variables impact children’s language. Policy implications, directions for future research, and study limitations are noted.

Transformational Leadership in the Planning of a Doctoral Program

Growing criticism of existing educational leadership preparation programs seems to focus on a lack of contextual relevancy and instructional leadership. Universities and school districts need to develop more formal, collaborative, long-term relationships focused on the nature of principal preparation, moving beyond acculturation to district norms and irrelevancy to building future leaders' capacity for continuous educational improvement. Educational administration as an applied field demands that we answer key questions regarding the development of effective practitioners.     

Educational decentralization policies in Argentina and Brazil: exploring the new trends

This paper compares educational decentralization policies implemented in Argentina and Brazil during the 1990s, focusing on the rationales and contexts of the policies, and through a review of secondary sources and some official documents. The paper argues that school decentralization, the movement toward transferring functions and responsibilities to schools, appears as a new and extended reform that was accompanied by more traditional forms of decentralization, but also by a process of centralization of planning and evaluation at the national level. This new form of centralization/decentralization is seen as linked to the neoliberal restructuring of the state, to pressures from globalization processes and forces, and to various internal demands for improving quality and efficiency in the delivery of education.     

Children Persist Less When Adults Take Over

Children need to learn to persist through challenges, yet adults sometimes step in to solve problems for them. Here, we looked at how adult taking over related to children’s persistence. In an observational study (N = 34, ages 4–8), we found that parents who took over more often during a challenging puzzle task rated their children as dispositionally less persistent. To establish whether taking over can cause reduced persistence, we ran two preregistered experiments (N = 150, ages 4–5). Children assigned to a taking over condition persisted less on a subsequent task compared to those in a teaching or a baseline condition. Reframing the context did not ameliorate the negative impact of taking over. The results suggest that taking over impairs children’s persistence.
