HIGH SCHOOL TEACHERS COGNITIVE SCHEMES SHOWN IN PROBLEM SOLVING APPROACHES BASED ON THE USE OF TECHNOLOGY
(2007)This study documents the type of proof schemes that high school teachers developed and used in problem solving scenarios that involve the use of dynamic software (Cabri-Geometry). Research questions that helped organize ... -
International Journal of Pure and Applied Mathematics
(2008)I.M. Isaacs has proven a very interesting theorem concerning solvability of polynomials by real radicals. His result deals with an irreducible polynomial over the field of rational numbers which has a real radical element ... -
Luminescent polystyrene films, a novel way to reduce styrofoam residues
(2015)Polystyrene (PS) films doped with blue, yellow and red organic pigments have been deposited on glass and on commercial LED chips by spray pyrolysis using recycled PS as precursor, at deposition rates between 100 and 200 ... -
MATHEMATICAL THINKING, CONCEPTUAL FRAMEWORKS: A REVIEW OF STRUCTURES FOR ANALYZING PROBLEM-SOLVING PROTOCOLS
(2010)Recently, it has been considered important to reflect on the coincidences between the mathematical thinking of the School of Mathematics and the Discipline of Mathematics. It is widely accepted that a professional mathematician ... -

Multichannel Detrended Fluctuation Analysis Reveals Synchronized Patterns of Spontaneous Spinal Activity in Anesthetized Cats
(2011)The analysis of the interaction and synchronization of relative large ensembles of neurons is fundamental for the understanding of complex functions of the nervous system. It is known that the temporal synchronization of ... -
PROCESOS DE DISEÑO E IMPLEMENTACIÓN DE TAREAS DE APRENDIZAJE MATEMÁTICO CON ALTA DEMANDA COGNITIVA
(2011)Resumen. Las tareas de aprendizaje son un elemento fundamental para que los estudiantes construyan conocimiento matemático. Sin embargo, una tarea por sí sola no basta para que los estudiantes logren un entendimiento ... -
RADICAL EXTENSIONS AND CROSSED HOMOMORPHISMS
(2001)If Q./F is a Galois extension with Galois group G and /x(fi) denotes the group of roots of unity in Q, we use the group Z1{G,fi(Q)) of crossed homomorphisms to study radical extensions inside Q. Furthermore, we characterise ...
