I've dealt with this every new school year, at 2 different schools -- admin requiring a change of curriculum at the last minute. This year, we were notified a week before school started. The two years before that, it was about a month into school, when we'd already been implementing another curriculum. I'm talking brand new textbooks, materials we'd never seen before, no trainings before implementing it -- just jumping right into the unknown. Honestly, I thought each change was for the best, but there was major pushback from the other teachers, particularly older ones who invested time in lesson plans/powerpoints/materials (understandably). Even though I was OK with the changes, it was a VERY stressful time, especially with all the other pressures of the new school year! Is this common? Have you experienced last minute curriculum upheavals? Opinions?
