From art to geometry: Aesthetic and beauty in the learning process
2015
Starting from the concept that knowledge comes as element of mediation between the convergent thinking, founded on experience, and the divergent thinking, placed in the perceptive, intuitive, creative dimension, in this paper we want to present an idea for developing an educational path combining the concept of “beauty” and some historical notes. It is possible to use this dissertation as a starting point to conceive a geometric laboratory that drawing inspiration from artistic works, get to create geometric shapes provided with fascinating symmetries
Propuesta de unidad didáctica del concepto de integral y del cálculo de primitivas
2010
En este Trabajo Fin de Máster se va a proceder a desarrollar una propuesta de unidad didáctica sobre el concepto de integral y el cálculo de primitivas. Ambos temas, en orden contrario, fueron de los que me encargué de desarrollar en mis prácticas. Como trataré más adelante, la forma tradicional de introducir estos temas a los alumnos es comenzar con el cálculo de primitivas o antiderivadas para después, una vez que los alumnos tienen suficiente destreza en el cálculo de las mismas, continuar con el teorema fundamental del cálculo y la regla de Barrow, es decir, las integrales definidas, convirtiéndose dichos conceptos en transparentes para los alumnos y sin llegar a ser asimilados correcta…
Are all denumerable sets of numbers order-isomorphic?
2018
International audience; In this paper we study cognitive conflicts on the issue of number sets being dense, ordered and denumerable. We first provide historical-epistemological background related to these notions. Then we consider the cognitive conflicts under the lenses of concept image and concept definition, which we use to analyse empirical data collected in order to understand better the didactical and cognitive issues at stake.
Performance of $b$-Jet Identification in the ATLAS Experiment

Estudio de funciones con geogebra
2012
Nuestra investigación, “Estudio de funciones con GeoGebra”, se ha desarrollado en el “Máster Universitario en Profesor de Educación Secundaria” de la Universitat de València. El estudio se centra en cómo alcanzar una correcta comprensión de los conceptos referidos a funciones haciendo uso del GeoGebra. El problema que motiva esta investigación radica en que, en los cursos tradicionales de 2º de Bachillerato, cantidades significativas de estudiantes no logran comprender los conceptos básicos de funciones, en particular, la tasa de variación media, derivada, monotonía, extremos y concavidad. El proyecto tiene como objetivo hacer una propuesta de trabajo basada en la utilización de GeoGebra, d…

Dynamic Potential of Feedback in Self-Regulated Learning and Motivation of Children with Mathematical Learning Difficulties
2017
The present study was designed to examine the effects of feedback conditions on learning and motivation of children identified with mathematical learning difficulties (MLDs). The performance of 76 fifth grade children on computational math skills and related task motivation was assessed. The groups of children were randomly assigned to one of two treatment conditions: immediate corrective feedback or delayed conventional feedback on two occasions. Results showed that children performed significantly better when they were provided with the immediate corrective feedback than when they were provided with the delayed conventional feedback. The findings suggest that provision of the immediate co…
O znaczeniu mowy egocentrycznej, dialogu i dyskusji w edukacji matematycznej uczniów w młodszym wieku szkolnym
2018
Verbal speech is conducive to the cognitive development of individuals and influences — in a positive way — the effectiveness of the process of learning. Language makes it possible to feel free while thinking and enables people to generate various ideas, to make hypotheses, or formulate different — even the most fanciful — theories which relate to phenomena examined by them. The considerations which the author makes on the role of speech in the process of learning became the incentive to carry out research among students of pedagogy, whose aim was to establish what views they present concerning the importance of egocentric speech, dialogue and discussion in the mathematical education of chi…
Nestriktās matemātikas morfoloģijas operatori: teorijas pamati un operatoru realizācija konkrētiem konjuktoru-implikatoru pāriem
2021
Maģistra darbā apskatīti matemātiskās morfoloģijas pamatoperatoru - dilācija, erozija, atvēršana, slēgšana - paplašinājumi nestriktās kopās. Vispārīga nestrikta morfoloģijas operatora definīcija realizēta konkrētiem konjunktoru-implikātoru pāriem. Operatoru realizācijā par konjunktoriem izvēlētas minimuma, reizinājuma un Lukasieviča t-normas un par implikatoriem - tām atbilstošie rezidiji un Klīnī-Dinesa implikācija. Konkrētie konjunktoru-implikatoru pāriem iegūtie operatori ilustrēti ar vizuāliem piemēriem, to realizācijai izstrādāta arī lietojumprogramma. Veikta iegūto rezultātu analīze.
