RESUMEN Introducción. Se presenta un estudio sobre las redes académicas generadas por las tesis doctorales de Educación Matemática leídas en

Resumen: Se presenta un estudio bibliométrico y de análisis de las redes de colaboración en los artículos de investigación en Educación Matemática publicados en una muestra de revistas españolas en el período 1999-2008. Para ello se han analizado los 774 artículos publicados en un conjunto de ocho revistas españolas representativas verificán-dose el cumplimiento de las leyes o patrones propios de la Cienciometría y comprobándose un bajo grado de colaboración científica entre los investigadores del área y también entre las instituciones.Palabras clave: Educación matemática, bibliometría, revistas científicas, colaboración. Research in Mathematics Education through Spanish scholarly publications

In recent years, the inclusion of computational thinking in education has become very important. This is a response to the needs of the evolution of our society and the skills demanded in students to obtain practical and integrated training. For this reason, the educational inclusion of these types of practices, strategies, and skills has been the subject of study in recent years. However, it is equally important to prepare and analyse the initial training of future teachers in this area. This research paper presents an empirical experience in which the degree of development of skills associated with computational thinking in preservice primary teachers is examined. For this purpose, programming practices with Scratch were carried out with a total of 149 students of primary education university degrees as part of their training in mathematics education. An experiment was designed for a control group and an experimental group with initial and final measurements using a validated diagnostic instrument consisting of 30 questions associated with computational concepts and their application: a computational thinking test. The result of the experience is positive, as a more significant improvement was observed in the experimental group, which was also accompanied by the impressions, provided by participants, that point in a positive, useful, and practical direction in terms of the development of this type of educational practice being relevant enough to introduce to the teaching and learning process of mathematics.

This paper focuses on the emergence of abstraction through the use of a new kind of motion detector-WiiGraph-with 11-year-old children. In the selected episodes, the children used this motion detector to create three simultaneous graphs of position vs. time: two graphs for the motion of each hand and a third one corresponding to their difference. They explored relationships that can be ascribed to an equation of the type A-B = C. We examine the notion of abstraction on its own, without assuming a dualism abstract-concrete according to which more of one is less of the other. We propose a distinct path for the attainment of abstraction, which involves navigating a surplus of sensible qualities. The work described in this paper belongs to early algebra, we suggest, because it involves the elementary symbolic treatment of unknowns and generals. More broadly, it advances a perspective on the nature of mathematical abstraction.
