Visualization and argumentation are central processes in the learning of geometry, giving rise to specific lines of research in mathematics education. However, it is worth asking whether they should be developed independently or if it is possible and in what way an articulation between them can be promoted. The objective of this paper is to search…

Team project-based learning (TPBL) combines two learning techniques: 1) project-based learning (PBL) and 2) teamwork. This combination leverages the learning outcomes of both methods and places students in a real work situation where they must develop and solve a real project while working as a team. TPBL has been used in two advanced database…

This paper compares state-led approaches to global citizenship education, driven by the concerns of national security, with the kinds of citizenship formation transnational youth acquire through their experiences in transnational social fields. I show that these transnational experiences--particularly their relationships with loved ones in their…

The aim of this contribution is to analyze the linguistic practices of a migrant collective, speakers of a minoritized language, from a glottopolitical perspective. This will be illustrated by the description of the communicative practices of the migrant workers from Galicia (Spain) in Hanover (Federal Republic of Germany) in the 1960s and beyond.…

This initial work on evaluating standardisation tries to explore to what extent standardisation can be evaluated in the same way as terminology planning and language policy and planning. The main reason for exploring this issue is that this kind of evaluation is necessary and has not been undertaken systematically. The work aims to verify the…

This article identifies the profiles of students whose performance is improved by the PBL method, and the influence of certain student-dependent factors that lead to improvement. Effects on performance vary from one student to another, so we distinguish between outcomes among low-performing, average-performing, and high-performing students. To…

Spain is currently living a transitional situation. In 2013 a new educational law was passed, the Organic Law that Modifies the Quality of Education (LOMCE). That law, among many other aspects, introduces the use of standardized external tests either to (1) guide or provide suggestions for the educational track, or (2) to obtain inferences towards…

This paper analyses the strategies used by pre-service primary school teachers for solving simple addition problems involving negative numbers. The findings reveal six different strategies that depend on the difficulty of the problem and, in particular, on the unknown quantity. We note that students use negative numbers in those problems they find…

This article reviews the journey of special education in Spain by considering the legal frameworks. It examines the extent to which legislation has tapped into the feelings of society in general towards people with disabilities who wish to secure inclusion in both education and society. It tracks the evolution of legislation, originally based on a…

The Program for the International Assessment of Adult Competencies (PIAAC) is a cyclical, large-scale study of adult skills and life experiences focusing on education and employment. Nationally representative samples of adults between the ages of 16 and 65 are administered an assessment of literacy, numeracy, and problem solving in technology rich…

Problems associated with the environment loom large over the future well-being of young generations. A previous issue of PISA in Focus (PISA in Focus 87) shows that in 2015 many 15-year-old students believed that the future -- their future -- was going to be worse, environmentally, than the present. In particular, only a minority of students…

Behavior problems are often observed in classrooms. The age at which problems appears is increasingly younger, and there are no interventions that ensure a reduction in such behavior problems among school age children. Research and previous evidence show the importance of social competence in this kind of prevention. Working with preschool and…

Recent research reveals an apparent paradox for U.S. millennials (born after 1980, ages 16-34): while they may be on track to be our most educated generation ever, they consistently score below many of their international peers in literacy, numeracy and problem solving in technology-rich environments. Equally troubling is that these findings…

The old myth about the ability and variability of potential in children is a comforting myth, for those who are uneasy with the degree of inequality they see and would rather seek to justify it than confront it. The myth of inherent potential helps some explain to themselves why they are privileged. Extend the myth to believe in inherited ability…

"Atlas de Geografía Humana" constitutes a critique of the much vaunted notion of a progressive Spain that has rectified the gender inequalities of the Francoist era, as one of the highly educated and successful protagonists, Fran, unwittingly adopts her mother's alignment with patriarchal norms. This novel elucidates the incompatibility…
