Jour 26 : On continue avec le domaine et l’image

Last night, the students worked on the DESMOS activity where they sorted cards based on
number sets.  I noticed a few common errors and because we were using the computers today, I wanted to take the opportunity to celebrate the mistakes, think about them and correctthem.  I had just heard Cathy Seeley speak at the AFEMO conference last week and she posted this growth mindset idea.

I showed the students all the « red » cards meaning that there were mistakes.  They immediately wanted to know how many « red » cards they had.  I had DESMOS in the ANONYMIZE mode in order to protect student identities but I couldn’t easily show them individually their mistakes without taking the mode off.  To my surprise and my content, they told me it didn’t matter.  They wanted to know their mistakes and they weren’t bothered if anyone knew they made a mistake.  We openly shared our mistakes, talked about them and corrected them.  Within 10 minutes, everyone had all « GREEN » cards and no one was embarassed.  Maybe this growth mindset talk is finally working and I am creating an environment where we aren’t ashamed to make a mistake!!!

J’ai déjà créé cette affiche pour ma salle de classe et je les ai fait imprimer!  J’ai hâte de les afficher cette semaine. 🙂

Finalement, avec le temps qui restait (c’était un horaire modifié ce matin), les élèves ont travaillé sur une activité DESMOS où ils devaient décider si un graphique était une fonction ou non et donné le domaine et l’image en utilisant la notation ensembliste.  C’est une évaluation au service de l’apprentissage et nous allons revoir les réponses ensemble demain.
