When I decided to try blended learning last year, I started with math because that’s where I saw the greatest frustration among my students. I had been teaching lessons mostly whole group to 34 students with very different needs. During guided practice, my two super advanced students were done with the problem within seconds and read novels while I hopped between the other 32 students to address their misconceptions. (I never told those students to “read when they were done.” It was obvious they had used this tactic for years to cope with a system that isn’t built to address their advanced abilities). By the end of the practice session, my most struggling student was in tears because my classroom tour never stopped at his desk to help him.
