#Enseignement des #Sciences Vous pensez que la démarche d’investigation est la meilleure méthode d’enseignement des sciences ? Ce n’est pourtant pas ce que montre la littérature scientifique. Résumé de l'article "There is an Evidence Crisis in Science Education". ⬇️⬇️

Teaching explicitly is not enough to prevent cognitive overload, because you can explicitly teach a lesson in which everything is new. The lack of incremental introduction of new material, alongside upwards of 90% review, is what overloads kids in many explicit teaching lessons.

Teach to mastery, and students retain it. That means little to no reteaching when the topic resurfaces. It’s pay now or pay later: if you treat everything as mere exposure, you’ll reteach endlessly. But invest in deep teaching upfront, and you’ll earn back time down the road.

The question that always comes up here is, “if most of it is review, how can we ever cover all the standards?” The question can be answered in many ways, but it represents a fundamental problem with our system: teachers are taught to teach for exposure and not for mastery.

“When we hand a ten-year-old a smartphone with access to infinite content streams, we are not liberating them; we are subjecting them to thousands of micro-decisions every day about what to watch, whom to follow, how to respond, and whether to keep scrolling.”

La "pédagogie différenciée", la "pédagogie de projet", la promotion de l'implicite, l'interdiction des devoirs... Toutes ces approches adoptées en France et intensément défendues à la fois par le ministère et le courant CFDT/Cahiers pédagogiques (Meirieu)... se révèlent être une…

High-order thinking depends on a strong foundation of knowledge. Without this foundation, there’s nothing to critically think about. That is why teaching “21st century skills” and “critical thinking” in isolation does not work. Let me explain with an analogy ⬇️

Le @CNRS rend hommage à Gilles Dowek, qui laisse derrière lui une œuvre scientifique et intellectuelle à la croisée de l’informatique et de la philosophie marquée par la volonté de transmettre. ➡️ ins2i.cnrs.fr/fr/cnrsinfo/ho… @lmf_lab @CNRSIdFSud @UnivParisSaclay @ENS_ParisSaclay

Quelle tristesse d'apprendre la mort de Gilles Dowek. Ses livres, conférences et interventions m'ont passionné.
