El presente artículo, sintetiza los resultados del análisis del aula de preescolar, en la Institución Educativa San Pedro Claver del Municipio de Puerto Boyacá. A partir de interrogantes alrededor del aulacomo espacio físico y de los objetos que confluyen en…

This paper critically analyzes the cognitive-map concept in terms oh) its subjectivity, as seen in the characterization of environmental knowledge as “images” of the world; b) its use of the information-processing approach in modeling environmental perception; c) its restricted representation…

Over four academic years a design experiment was conducted involving four online university courses with the goal of shifting from Guided to Self-Organized Inquiry to foster Knowledge Building communities in the classroom. Quantitative analyses focused on notes contributed to collective…

Adaptive finite element methods (FEM) have been widely used in applications for over 20 years now. In practice, they converge starting from coarse grids, although no mathematical theory has been able to prove this assertion. Ensuring an error reduction rate…

A new computable a posteriori error estimator is introduced, which relies on the solution of small discrete problems on stars. It exhibits built-in flux equilibration and is equivalent to the energy error up to data oscillation without any saturation assumption.…

Data oscillation is intrinsic information missed by the averaging process associated with finite element methods (FEM) regardless of quadrature. Ensuring a reduction rate of data oscillation, together with an error reduction based on a posteriori error estimators, we construct a…

This paper presents an extension of an ongoing study of online learning framed within the community of inquiry (CoI) model (Garrison, Anderson, & Archer, 2001) in which we further examine a new construct labeled as learning presence. We use learning…

In this article, I examine shamanic initiation narratives, the stories told by urban mestizo shamans in northwest Amazonia to explain their knowledge of Amerindian plant medicine, to illuminate the sociohistorical context in which they emerge. Using a geocritical approach to…
