Revistas brasileñas de Educación en SCOPUS: un análisis bibliométrico
(Pitt Open Library Publishing, 2017)
Objetivo. El auge de la producción científica en los últimos años ha motivado la realización de diversos estudios bibliométricos. En esta línea, este trabajo analiza las revistas brasileñas presentes en el índice de impacto ...
On the connectedness of a random closed set of a Euclidean space
(Elsevier, 2022)
Our aim is to obtain a suitable characterization of certain topological properties of a random closed set through its capacity
functional. The main technique mixes two different fields: on the one hand, the abstract ...
La resolución de problemas basada en el método de Polya usando el pensamiento computacional y Scratch con estudiantes de Educación Secundaria
(Universidad de Oviedo, 2020)
La inclusión de la tecnología como recurso educativo supone un nuevo escenario de trabajo en el aula que requiere de un proceso de investigación empírica para valorar su efectividad. El presente trabajo consiste en un ...
Body motion, early algebra, and the colours of abstraction
(Springer, 2020)
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 ...
Language acculturation among the children of immigrants in Spain at the end of the prodigious decade of immigration
(Editorial Universidad de Alcalá, 2023)
In Spain, few studies have analyzed how children of immigrants
combine the acquisition of Spanish with the maintenance/acquisi-
tion of heritage languages. This paper moves into that direction by
exploiting data from a ...
Instrumentos para la evaluación del sentido numérico en los primeros años de aprendizaje matemático
(Octaedro, 2022)
En el ámbito de la investigación en educación matemática, la importancia del sentido numérico ha estado presente desde hace décadas. Sin embargo, a pesar de esta larga trayectoria, no se ha llegado a un consenso sobre su ...
Questioning the Shanghai Ranking methodology as a tool for the evaluation of universities: An integrative review
(Springer, 2018)
This integrative review reports on methodological questions about the Shanghai Ranking
as a tool for the evaluation of universities, questions that are extensible to other rankings.
The paper presents a list of methodological ...
New Bounds for Three Outer-Independent Domination-Related Parameters in Cactus Graphs
(MDPI, 2024)
Let G be a nontrivial connected graph. For a set D _ V(G), we define D = V(G) n D. The set D is a total outer-independent dominating set of G if jN(v) \ Dj _ 1 for every vertex v 2 V(G) and D is an independent set of G. ...
Stability of maximal hypersurfaces in spacetimes: new general conditions and application to relevant spacetimes
(Springer, 2017)
We obtain new simple sufficient conditions to ensure the stability and strong stability of maximal hypersurfaces (without boundary) immersed in an arbitrary spacetime. Several applications to maximal hypersurfaces in a ...
On the concept of infinitesimal position vector fields in Galilean spacetimes
(World Scientific, 2022)
We introduce two different ways to establish the concept of infinitesimal position vector field between “infinitesimally nearby” observers in a Galilean spacetime as well as show their mathematical equivalence. We also use ...
