The Speedup

Me, in comments:

One problem with stories like this is that the teaching load is not directly questioned. Twenty years ago it was axiomatic in US school reform that 80 students was the maximum load a teacher should have (see the Coalition of Essential Schools Common Principles). Three different preps for a developing teacher is nearly impossible. High performing countries do not drive their teachers this way.

Teaching IS uniquely demanding, but we are also simply overworking our teachers.
