Christian Walter (FMSH) : Enjeux politiques des normes financières

Dans le cadre de la semaine du Nouveau Quartier Latin qui s'est déroulée entre le 21 mai et le 3 juin 2012, sept grandes institutions ont ouvert leurs portes : animations, conférences, performances artistiques, lieux insolites, fanfares et visites guidées… se sont succédés. L’EHESS et la FMSH ont organisé le 31 mai dans l'atrium du France - 190-198 avenue de France, 75013 Paris, le printemps des sciences humaines et sociales. Au programme : des livres, du numérique, des cartes et une dizaine de conférences de 15 minutes qui ont été filmées. >> Pour connaître le programme complet la ...

SECRET LIFE OF SPACETIME

Combining the principles of general relativity and quantum theory still remains as elusive as ever. Recent work, that concentrated on the points of conflict and contact between quantum theory and general relativity, suggests a new perspective on gravity. It appears that the field equations of gravity in a wide class of theories - including, but not limited to, standard Einstein's theory - can be given a purely thermodynamic interpretation. In this approach gravity appears as an emergent phenomenon, like e.g., gas or fluid dynamics. I ...

FORMATION ET ÉVOLUTION DES SYSTÈMES PLANÉTAIRES ET EXTRASOLAIRES

Since the discovery of an extended disk of dust around beta Pictoris in the late 80's, this system has been intensively observed and modeled, in connection with planetary system formation/evolution. The presence of planets has been proposed over 2 decades to explain various observations, and high angular resolution imaging allowed us recently to directly image a planet orbiting about 9 AU from the star; this is so far the closest extrasolar planet imaged. I will present a brief overview of the main indirect signatures of ...

“Come on guys, use your sense!” Illuminating the ‘incarnate’ work of teaching - Koshmann

Twelve years ago, Lehrer and Schauble rolled out a newly-designed math and science curriculum in a particular 5th gradeclassroom (Lehrer & Schauble, 2004, 2011). In this talk, I will examine a brief fragment of interaction recorded in this classroom.The participants observed here are trying to work out how to graphically represent a set of data. It is a problem of reconciling therange of values to be presented with the space available on the sheet of graph paper with which they are working. In the courseof working out this problem, they engage in the concerted generation of a series of number ...

A Design-Based Research Approach to Understanding Complex Learning - Hmelo silver

Complex learning environments require complex approaches to understanding both what and how students learn. In this talk, Iwill describe design-based research methodology and discuss how I have used this approach to understand learning intechnology-rich learning environments. One example will show how research on expertise in complex systems led to the designof a technology-rich learning environment for middle school science classrooms. This program of research used a combinationof laboratory and classroom research. Time permitting, a second example will bring together research on problem-basedlearning that went from quasi-experimental research showing what students learned to more qualitative research that explainshow students learn.

Scaling Up Proven Programs: Why and How - Slavin

In order to bring about significant and cost-effective improvements in student learning in whole systems of schools, it isimportant to identify effective programs, practices, and materials, and then scale them up broadly. This is the way fields such asmedicine, agriculture, and technology have advanced, and education must embrace the same dynamic. But how can this bedone? This presentation discusses the why and the how of scaling up proven programs in education. First, it discusses howpromising programs need to be evaluated to ensure that they are worth scaling. Then it discusses how complete programsrequiring extensive professional development and coaching can be ...

Quelles évidences et quels succès, pour quelle communauté éducative ? - Potte-Bonneville

Je souhaiterais soumettre à la discussion trois types d’interrogation, à partir de l’intervention de Robert Slavin. 1/ Questions descientificité : quelle conception le recours à l’evidence-based practice implique-t-elle, quant au rapport entre la connaissance etles sujets susceptibles de la mettre en oeuvre ? 2/ Questions de finalité : quelle place faire à la notion de success dans laconstellation des fins traditionnellement poursuivies par l’éducation ? 3/ Questions de communauté : quels modèles de lacommunauté éducative, s'il s’agit à la fois de rendre possible le succès pour tous, le succès par tous (à travers des formesd’apprentissage coopératif), et le succès adossé ...
