In this article, we examine eighth graders' incorrect responses to a specific task on a national standardized assessment of mathematics. The task asked students to write the formula for the perimeter of a given figure as a function of a variable. We focus on incorrect responses to better understand students' difficulties with the algebraic…

The study of the territorial difference in educational achievement is a widely debated topic, in particular in Italy for the presence of the well-known strong regional disparities. National and international large scale assessments confirmed that the main characteristic of the Italian school system is the geographical cleavage between North and…

This study is aimed at exploring how different formulations of the same mathematical item may influence students' answers, and whether or not boys and girls are equally affected by differences in presentation. An experimental design was employed: the same stem-items (i.e., items with the same mathematical content and question intent) were…

We describe how young students situate themselves with respect to astronomy through an identity framework that features four dimensions: interest, utility value, confidence, and conceptual knowledge. Overall, about 900 Italian students, from 5th to 9th grade (9-14 years old), were involved in the study. We tested our model using confirmatory…

We present the result of an eight-year didactic experiment in two primary school classes involving comparative geometry activities: a comparison between Euclidean plane geometry and spherical geometry that took place over five years. Following the didactic experiment, three years on from the end of the experiment, final questionnaires were…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

This study investigated the links between students' behavioral problems, student--teacher conflict, and students' involvement in bully, victim, and bully/victim roles in adolescence. The role of student-teacher conflict as moderator of the association between students' behavioral problems and their involvement in each bullying role was examined.…

While homework is a frequent source of distress, positive attitudes of parents can help students develop positive emotions and self-efficacy regarding homework. In this study, we tested the hypothesis that parents' emotions, favored by autonomous motivation, directly and indirectly relate with students' emotions through their self-efficacy with…

Most existing research indicates that working students perform more poorly than do full-time students on standardized achievement tests. However, we know there are wide international variations in this gap. This article shows that national and international contexts help to explain the gap in the academic performance between working and nonworking…

Most studies on narrative competence have focused on monolingual subjects, and there are very few studies which address this issue in bilingual subjects dealing with two language systems. In the present case study we analyzed and compared the textual and narrative written skills of three deaf and three hearing adolescents attending eighth grade at…

This study investigated the relationships between three psychopathic dimensions (callousness/unemotionality, grandiosity/manipulation, and impulsivity/irresponsibility) and reactive and instrumental aggression in a community sample of early adolescents (N = 243, age M = 12.29, SD = 1.18). The moderating role of moral disengagement (MD) was also…

Previous research has identified school bonding as protective against substance use during adolescence. However, there is still a question as to whether school involvement predicts changes in substance use or if substance use actually predicts changes in level of school bonding. This study investigated the relationship between school bonding and…

The Senegal Project is the culminating project in a unit on cultural foods in an 8th grade family and consumer sciences (FCS) course. Initially, students take a quick world tour by studying and cooking foods from Mexico, Italy, China, and India followed by a "more depth and less breadth" study of Senegal, a country with a culture vastly…
