Development of Math Attitudes and Math Self-Concepts: Gender Differences,Implicit–Explicit Dissociations,and Relations to Math Achievement

Three hundred and ninety-one children (195 girls; M_age = 9.56 years) attending Grades 1 and 5 completed implicit and explicit measures of math attitudes and math self-concepts. Math grades were obtained. Multilevel analyses showed that first-grade girls held a strong negative implicit attitude about math, despite no gender differences in math grades or self-reported (explicit) positivity about math. The explicit measures significantly predicted math grades, and implicit attitudes accounted for additional variance in boys. The contrast between the implicit (negativity for girls) and explicit (positivity for girls and boys) effects suggest implicit–explicit dissociations in children, which have also been observed in adults. Early-emerging implicit attitudes may be a foundation for the later development of explicit attitudes and beliefs about math.     

Students' Agentic Engagement Predicts Longitudinal Increases in Perceived Autonomy-Supportive Teaching: The Squeaky Wheel Gets the Grease

Recognizing that teachers' motivating styles predict students' classroom engagement, we investigated whether students' classroom engagement might predict a change in teachers' motivating styles, though we investigated only students' perceptions of these changes. Using a self-determination theory framework and a classroom-based longitudinal research design, 336 Peruvian university students self-reported their teachers' perceived autonomy-supportive teaching and four aspects of their own engagement (behavioral, emotional, agentic, and cognitive) at the beginning (T1) and end (T2) of a semester. As expected, earlysemester perceived autonomy-supportive teaching predicted longitudinal increases in all four aspects of students' late-semester engagement. More importantly, students' early-semester agentic engagement predicted longitudinal increases in perceived autonomy-supportive teaching, which suggests that students' classroom engagement may recruit greater perceived autonomy support.     

Determinants and patterns of physical activity practice among Spanish university students

The purpose of the present study was to investigate the socio-demographic and lifestyle determinants of physical activity practice, as well as the motivations for being or not being physically active in Spanish university students. A representative sample of students from a Spanish university (n = 2,051; 42.1% males; mean age 21.9, s = 4.8 years) participated in the present cross-sectional study. A questionnaire including questions regarding lifestyle, dietary habits, parents' characteristics, and physical activity habits was administered to the students. The socio-demographic and lifestyle determinants of physical activity practice were assessed using multivariable logistic regression. 68.4% of men and 48.4% of women reported to practise physical activity in the present sample. Those who practised physical activity consumed more fruits and were less likely to be smokers compared to non-physically active students. Also, physically inactive men spent more time in front of the computer and physically inactive women spent more time in front of the TV and were more likely to be frequent alcohol consumers. Maternal educational level and maternal physical activity habits were also important determinants of physical activity practice among men and women respectively. In conclusion, physically active students tended to engage in other healthy habits in the present population, suggesting the clustering of healthy or unhealthy lifestyle factors among specific subgroups.

Preventing Violence by Promoting the Development of Competent Conflict Resolution Skills: Exploring Roles and Responsibilities

This article explores the relationship between conflict and violence through a review of the literature about young children's conflict with their peers. Information about the nature of young children's conflicts and how teachers respond is presented and discussed in relation to 3 questions. First, do conflicts between children lead to violence? Second, what constitutes competent conflict resolution behavior? Third, how do children develop competent conflict resolution skills? This review of the literature indicates that conflicts between children do not naturally lead to violence. Rather, it is when children are unable to resolve their own conflicts, and when they are not supported in their efforts at resolutions, that violence is likely to result. While conflicts with peers provide a natural opportunity for children to develop competent conflict resolution skills, teachers must provide assistance as needed. Suggestions for further reading on this topic are provided.     

Identification,Interpretation—Evaluation,Response: An alternative framework for analyzing teacher discourse in science

Although research has come to recognize the importance of studying classroom-based student–teacher discourse in science, the emphasis remains largely on teachers' abilities to ask questions and provide students with feedback, or on students' abilities to ask questions or engage in argumentative discourse. Consequently, little research has focused on the discourse elements relating to teacher–student discourse interactions. In this article, we argue for a shift of research attention toward describing what the teacher is responding to (Identification of student inquiry), the process of deciding how to respond (Interpretation—Evaluation of student inquiry), and how the teacher is responding (Response to student inquiry). We propose a new methodological approach for studying teacher discourse, which involves a framework we developed while analyzing 1,385 minutes of fifth grade, whole-class science conversations covering a 2-year period and facilitated by an experienced science teacher. Then, as a case in point, we applied our framework to the teacher discourse data of the study, aiming to show that the framework can be a useful tool for examining how a teacher supports students' inquiry.     

The Case of the Greeting-Card Cripple

Students in the United States need diversity skills that enable them to function in an increasingly interdependent and varied world. Internet technology provides an untapped resource for assisting children to understand and value diversity. In this article, the authors present three skills that are important to students as they interact in the global community. In addition, the authors recommend Internet technology-based resources that teachers may use to assist students in acquiring diversity skills.     

Research as a vital action in the DIPEC territory

The authors present the Didáctica de las Prácticas Escolares Cotidianas – The Didactics of Everyday School Practice (DIPEC). From their point of view, it owes its specificity to certain special characteristics, one of which is the inevitable presence of concrete, immediate teaching action, which presents particular problems and therefore particular ways of dealing with them. This article includes an example of a problematic situation, the way it was handled using Paulo Freire's methodology and the action subsequently developed.
