3. Cause & effect theory
IF everyone follows the schedule, doing their job the one best way, with occasional tests and a side-repair process
THEN no one slows down the production line and yet quality is still maintained. And it works! For making Model T cars.
IF Taylor's method works so effectively everywhere else (agriculture, mining and manufacturing)
THEN Taylor's method can be adopted for education.
This was the reasoning for adopting Taylor's method back in 1913.
See Patrick Callahans book, Education and the cult of efficiency, to see the history, blow by blow, of how education leaders were pressured into, and finally acquiesced to adopting Taylor's method in education.
The actual cause & effect theory which explains the results we get in schools today is:
a one-size-fits-all follow-the-schedule method is used
some students will be ahead, bored and idle, and others behind, falling more behind and believing it is their fault.
This explains why the more years students spend in school, the more they fall behind relative to grade level.
A new cause & effect theory
students become more and more wise and responsible, through a series of inner psychological exercises
able to skillfully plan their own learning using lean/agile techniques
it becomes safe to provide students the autonomy they need to plan learning and create and learn to their own ability.
This makes logical sense; and it can be done. We have evidence.
