Professional learning
I work with teachers, school leaders, and school divisions and districts on Building Thinking Classrooms, instruction, and assessment. Most of that is a series of workshops across a school year, often with days in classrooms co-teaching alongside teachers and with their students. I also speak at conferences, and I co-wrote a book of thinking classroom tasks with Peter Liljedahl.

Workshops and classroom teaching
The work I like best is with one school or division over a year: a first workshop, then follow-up sessions and time in classrooms as teachers try things. It can also be a single day, in person or online.
Introduction to Building Thinking Classrooms
Teachers experience a thinking classroom as students, then we unpack what made it work and how to start.
Next Steps in Building Thinking Classrooms
For teachers who have started: consolidation, micro-moves, managing behaviour and building collaboration.
Assessment in Building Thinking Classrooms
Formative assessment and grading that fit a thinking classroom, so students know where they are in their learning.
Taking Building Thinking Classrooms Beyond Math
Building Thinking Classrooms in science, ELA and social studies.
Co-teaching
In classrooms alongside teachers and their students, from kindergarten to high school.
Leading a thinking classroom school
For school and division leaders supporting teachers through the change.
