This dissertation examines the development of combinatorial reasoning in high school students through an in-depth analysis of a problem-solving session involving the Pizza Problem. The study, part of the long-term Rutgers-Kenilworth longitudinal research project, focuses on four 11th-grade students as they explore and connect concepts related to…

The relation between learners' metacognitive skills and conceptual understanding is often portrayed as an input-output relation when dealing with science, technology, engineering, and mathematics (STEM) and non-STEM disciplines. However, studies indicate that not all pedagogies yield positive correlations between learners' metacognitive skills and…

This study investigated the predictive effect of 11th grade Taiwanese students' (N = 878) self-assessed critical thinking, group participation self-efficacy, and active learning on their genuine learning interest (GLI) in socio-scientific issues (SSI). Results showed that active learning had a direct effect on GLI, while critical thinking and…

In this paper, we continue describing the project and the experimentation of "Ricerca Operativa Applicazioni Reali" (ROAR; in English, Real Applications of Operations Research), a three-year project for higher secondary schools, introduced. ROAR is composed of three teaching units, addressed to Grades 10, 11, and 12, respectively, having…

This study investigates the relationship between students' problem-solving skills in solving mathematical problems and asynchronous collaboration in digital learning environments. The research focuses on the Digital Math Training (DMT) project, designed by the DELTA research group at the University of Turin, which aims to enhance students' digital…

This paper reported an exploratory study that examined secondary school students' understanding of collaborative discourse in a computer-supported knowledge building environment in characterizing and scaffolding their engagement in productive online discourse. The participants were thirty-eight secondary school students in a visual arts course. A…

I explore students' discourses in small groups working on mathematical problems using GeoGebra, focusing on the Cartesian connection between algebra and geometry. Specifically, the interest lies in what is internally persuasive for students in upper-secondary school (11th grade) with histories of low attainment. Three problem-solving episodes are…

Although research has always related e-portfolios to self-regulated learning, recently agency, which includes individual, relational, and contextual domains, has also been highlighted. Likewise, agency has been explored in technological environments that support collaborative and co-design learning processes. This study, investigating the…

STEM education seeks to respond to the challenges of the fourth industrial revolution and to prepare future generations of the city in 21st century skills and scientific and technological vocations. This article aims to identify the characteristics of the educational experiences lived in processes of partial and total implementation of the STEM…
