We gave participants diagrams of traffic on two roads with information about eight attributes, including the type of each vehicle, its speed, direction and the width of the road. Their task was to record and organize the data to assist city planners in its analysis. Successfully encoding the information required the creation of a case, a physical…

The current study aims to show the transition skills of sixth grade students between the representations (numerical, model, number line and verbal) given in addition-subtraction operations in fractions and to analyse the ability of the students to construct each representation type. In this research, case study method was used in terms of the…

Interpersonal relationships during adolescence can be powerful avenues for personal development. As school is a universal context for youth, positive teacher-student relationships (TSRs) are one potential source for such developmentally promotive relationships. Unfortunately, research has shown a decline in the quality of teacher-student…

Mechanistic reasoning is an epistemic practice central within science, technology, engineering, and mathematics disciplines. Although there has been some work on mechanistic reasoning in the research literature and standards documents, much of this work targets domain-general characterizations of mechanistic reasoning; this study provides…

Relational reasoning, the ability to discern meaningful patterns within a stream of information, is considered a critical capacity for students. However, little is known about how this ability is demonstrated by children of different ages in the context of discourse with a more knowledgeable other. Thus, this study sought to investigate the ways…

In sub-Saharan Africa, young women are at the highest risk of HIV infection. Comprehensive sexuality education and open parent-child communication about sex have been shown to mitigate risky sexual practices associated with HIV. This study aimed to identify sources of HIV prevention knowledge among young women aged 10-14 years and community-based…

Few studies have examined the impact of mastery learning on mastery goal structures or even on students' motivation more generally. In this study, we examined one middle school that implemented a schoolwide mastery learning system, conducting interviews with a sample of administrators (n = 3), teachers (n = 4), and students (n = 9) to determine…

Both scientists and policy-makers emphasize the importance of education for influencing pro-environmental behavior and minimizing the effects of climate change on biological and physical systems. Education has the potential to impact students' system knowledge--their understanding of the variables that affect the climate system--and action…
