Most school improvement theory's i. E. Cramers-Kyriakides focus on the proportionally dominant role of teacher in boosting learning results.
However students ownership of learning, initiative, respinsibikity and accountability are ignored in these family of models.
The reason is that it is more practical to have teachers as a control input because due to emloyment contracts they ceade sovereinty to the system's hiersarchy. However this is a practical /convenience not an effectiveness theoretical reason so not so valid.
