Why is it surprising?

We're rather used to the idea of progress in most areas of human endeavor. It's fairly absurd to believe rolling back the last 200 years of progress would lead to measurably better outcomes is absurd in fields like medicine, industry, science, history, technology, cuisine, transportation, ...

That it seems to be that case in education seems to me to qualify for the label of surprising.
