Understanding the structure of the set of rational numbers: a conceptual change approach.
In the present article, we argue that the conceptual change approach to learning can apply in the case of mathematics, taking into consideration the particular nature of mathematical knowledge and the neurobiological bases of mathematical cognition. In the empirical study that is reported in this article, we investigated ninth graders' understanding of algebraic and structural properties of rational numbers, from a conceptual change perspective. We make the point that understanding rational numb

La evaluación social e individual en la era de la educación a distancia en la globalización
En la globalización tan ampliamente fomentada, especialmente por la educación a distancia, debemos cuestionarnos sobre los valores que vivimos en nuestras culturas locales. La evaluación que instauramos dentro de nuestros cursos puede también convertirse en otro mecanismo de homogenización. Para contrarrestar estas desventajas y poder construir juntos sociedades distintas pero solidarias, propongo un análisis de la evaluación como vehículo ideológico de perpetuación de la distribución

Exploring Light: Absorb, Reflect, Transmit or Refract?
In a hands-on way, students explore light's properties of absorption, reflection, transmission and refraction through various experimental stations within the classroom. To understand absorption, reflection and transmission, they shine flashlights on a number of preselected objects. To understand refraction, students create indoor rainbows. An understanding of the fundamental properties of light is essential to designing an invisible laser security system.

A methodological note on modeling the effects of race: the case of psychological distress
Psychological distress is an important indicator of the mental well-being of the population. Findings regarding racial differences in distress are inconclusive but may represent an important pathway through which disparities exist across a number of physical health outcomes. We used data from the 1994 Minority Health Survey, a nationally representative multiracial/ethnic sample of adults in US households, to examine racial/ethnic differences in psychological distress (n = 3623).

Racial Differences in 30-Day Mortality for Pulmonary Embolism
Objectives. Previous studies reported a higher incidence of in-hospital mortality for Black patients who had pulmonary embolism than for White patients.

Sartre à Venise, une palinodie

L’attachement de Sartre à Venise est profond et durable, mais aussi mystérieux car tout chez Sartre paraît s’opposer à Venise. Sartre trouve à Venise la possibilité de changer radicalement de projet existentiel, d’être « un autre Sartre », d’écrire, à travers une utilisation fréquente de la métaphore, cette espèce de contre-Nausée qu’est La Reine Albemarle ou le dernier touriste, avant d’en sortir, et de revenir à son essai engagé sur Les communistes et la paix.
