The aim of the present study was to examine whether class-level characteristics, such as class size and gender ratio, could contribute to explaining different levels of bullying, victimization, and perception of defending between classes. Seven-hundred-and-sixty-three students (M[subscript age] = 12.96, SD = 1.22; 54.4% boys) from 42 Portuguese…

The samples were 4 groups, viz; 10 expert teachers for interviewing on the draft of the variable to develop the indicators; 12 teachers who won Guru Awards from Teachers Council for…

This study aims to investigate whether the perceived social support and coping styles are predictors of suicide probability by gender. The study was conducted with 445 high schools students, 227 girls, and 218 boys. The participants were aged between 14 and 18, and their average age was 15.90. Data were collected through the "Multidimensional…

It is well documented that parental behavior is a strong determinant of a child's educational achievement and general well-being. Thus, it seems relevant to analyze the determinants of parental involvement in the education of their children. While most studies analyze the effect of family characteristics (such as parents' education, ethnicity, or…

Among the wide range of factors related to the acquisition of statistical knowledge, competence in basic mathematics, including basic probability, has received much attention. In this study, a mediation model was estimated to derive the total, direct, and indirect effects of mathematical competence on statistics achievement taking into account…

This paper examines the effect of the introduction of an academic dismissal (AD) policy (i.e. an intervention, which can lead to compulsory student withdrawal) on student dropout, student graduation rates and satisfaction with the study program. Using a difference-in-differences type of estimator, we compare programs that introduced an AD policy…

The acquisition of digital skills, media diet management, and general knowledge of ICT, is essential for the development and empowerment of audiences in the current media ecology, particularly considering the political and social challenges of the Latin American environment. In that sense, the study of media competence is urgent for sizing up the…

This paper estimates the treatment effect of grade repetitions in French junior high schools, using a value-added test score as outcome and quarter of birth as instrument. With linear two-stage least squares, local average treatment effect is estimated at around 1.6 times the standard deviation of the achievement gain. With non-linear…

Introduction: Several studies show that one of the essential factors in the way teachers use Information and Communication Technologies (ICT) in their lessons are the beliefs they hold regarding ICT as tools for teaching and learning. This study analyses the relationship between these beliefs and the way teachers use ICT in the classroom through…

Students of all ages face severe conceptual difficulties regarding key aspects of evolution-- the central, unifying, and overarching theme in biology. Aspects strongly related to abstract "threshold" concepts like randomness and probability appear to pose particular difficulties. A further problem is the lack of an appropriate instrument…

Program satisfaction, self-efficacy to change, and willingness to change, are dispositions that influence physical education teacher change. The study purpose was to validate an instrument measuring program satisfaction, self-efficacy to change, and willingness to change relative to teachers' likelihood to change. A 15-item Teacher Change…

Objective: This study examined the association between positive screening for depression, current exposure to microaggressions, distress evoked by microaggressions, and subjective social status among high-achieving minorities. Methods: An observational cross-sectional study was conducted using the Racial Microaggressions Scale, MacArthur Scale of…

The ability to use numerical information in different contexts is a major goal of mathematics education. In health risk communication, outcomes of a medical condition are frequently expressed in probabilities. Difficulties to accurately represent probability information can result in unfavourable medical decisions. To support individuals with…

Jamaican immigrant students are highly represented in U.S. public schools, primarily in regions concentrated throughout the east coast. Many of these students and their families have personal and social concerns that have implications for school counselors. In particular, scholars suggest that among this population, harsh methods of child…

In 1963, the Nobel Prize-winning ethologist Niko Tinbergen proposed a framework for the scientific study of animal behaviour by outlining four questions that should be answered to have a complete understanding: causation, ontogeny, function and evolution. At present, Tinbergen's framework is still considered the best way to guide animal…
