- That there is some outside agent that observes progress and "improves" someone
- That such progress can be quantified, and comparable
- That such measurement is the only way to acertain the truth of progress.
- That there is such a thing as an universal standard by which someone needs to be educated
- That the purpose of education is to produce productive members of society
- That a person starts education as a "blank slate", ready to be filled by what the teacher is teaching
- That the capacity to learn and the potential to be educated is fixed, and therefore, some should be selected for even further education
- That learning only happens when there's an outside agent educating the person
There are so many problematic things with this frame, even if it is fairly mainstream.
