Excellent speaker. Update the core operating system of education. It has not changed from Industrial Age in the sixties. The hardware is the tangata- the people. The software is the equipment.
Change is uncomfortable but not hard when put in context with fighting a war, settling Midwest America or raising children as a single mother in poverty.
Change can happen. Embrace the discomfort.
Obstacles in school to change are fear and inertia, the anchors of my class, my time, my time, my subject and silos.
