Cuestiones epistemológicas y estudios de caso

En un país -Francia- donde el campo del teatro está estructurado culturalmente durante décadas, el Teatro Aplicado es una noción que a menudo aparece como ancillar, frente a un arte institucionali-zado, incluso mirificado. Por un lado, estaría el Teatro, puro, noble, auténtico y por otro, estarían sus avatares: el teatro de empresa, el teatro para el desarrollo personal, el teatro para patologías, etc. Si tienen la misma fuente, su consanguinidad no deja de asustar. ¿cómo pueden unos artistas que crean alejados de cualquier coacción exterior pertenecer a la misma familia del teatro que unos actores o directores que "obedecen" a un encargo, en un contexto específico, con un público muchas veces participantes de talleres ... y que son por tanto prisioneros, en cierto modo, de un arte instru-mental izado? A este problema ético, este libro intenta responder, a través de ejemplos concretos, para una mayor comprensión inrerculrural Francia/ Colombia.In a country -France- where the field of theater has been culturally structured for decades, Applied Theater is a notion that often appears as an ancillary, in the face of an institutionalized, even mirified, art. On the one hand, there would be the Theater, pure, noble, authentic and on the other, there would be its ups and downs: company theater, theater for personal development, theater for pathologies, etc. If they have the same source, their consanguinity does not stop frightening. How can some artists who create far from any external coercion belong to the same theater family as some actors or directors who "obey" a commission, in a specific context, with an audience that is often workshop participants... are they therefore prisoners, in a certain way, of an instrumented art? To this ethical problem, this book tries to respond, through concrete examples, for a greater intercultural understanding France/ Colombia.Bogot

Du calcul réfléchi à la multiplication posée

L’observation de difficultés d’élèves de cycle 3 dans la réalisation de l’algorithme de la multiplication posée amène à se demander quel continuum existe entre calcul réfléchi et techniques opératoires. Dans quelle mesure les élèves de cycle 3 font-ils appel au calcul réfléchi dans la réalisation de la multiplication posée? Les programmes préconisent l’établissement d’un lien étroit entre apprentissage des techniques opératoires, propriétés et sens des opérations. Ce travail sur le sens et les propriétés passe par la pratique du calcul réfléchi. Instaurer des allers-retours entre technique automatisée et pratique réfléchie semble indispensable, or l’apprentissage de la multiplication posée emprunte une direction : du calcul réfléchi vers l’opération posée. Notre protocole propose d’emprunter la direction inverse : partir d’une réalisation automatique, pour parvenir à une approche plus réfléchie en imposant de la nécessité de reconnaître les calculs intermédiaires. L’expérimentation a permis de montrer comment des élèves de cycle 3 pouvaient passer d'une méthode automatique apprise en classe, dont le sens a été perdu de vue, à un travail faisant appel à une réflexion retrouvée sur le sens

: École d’été 2021 - Contraintes de courbures et espaces métriques

This is a series of lectures on Bishop--Gromov's type inequalities adapted to metric spaces. We consider the case of Gromov-hyperbolic spaces and draw consequences of these inequalities such as compactness and finiteness Theorems. This course is intended to be elementary in the sense that the necessary background is described in detail

: École d’été 2021 - Contraintes de courbures et espaces métriques

The purpose of this course is to introduce the synthetic treatment of sectional curvature upper-bound on metric spaces. The basic idea of A.D. Alexandrov was to characterize the curvature bounds on the sectional curvature of a Riemannian manifold in term of properties of its distance function, and then to consider metric spaces with these properties. This approach turned out to be very fruitful and it found many applications, bringing geometric ideas to other settings.In this course we will introduce the metric spaces with a curvature upper-bound in the sense of Alexandrov, and derive some of their geometric properties. The subject is very vast and it is not possible to be exhaustive in the limited time of this course. We will concentrate on some properties, both local and global, emphasizing that these metric spaces share many properties with manifolds of bounded curvature
