It's a bold story but I can't help but feel angry despair at all the education he stole from so many children over so many years. Despicable cowardice.
The educators in my life who employed a lot of discussion are some of the highest value ones.
It's not like the subjects he taught require more.
Someone should get feedback from his students. Would be very interesting to get their take on their experiences.
I met a fellow who was traumatized by being forced to try to learn to read before he was ready (1st grade). He eventually learned how to read, in spite of the System's attempt to prevent it.
The most important factor in teaching kids to read is waiting for them to be ready.
