I’m looking for a word whose definition I remember.
The word refers to a teaching practice. When a teacher is introducing an extremely difficult subject that is really entirely beyond the abilities of her students, she may sometimes present introductory material that, from the perspective of an expert in that field, is not strictly correct. She does this so that her students can begin their investigations – can have “something to go on.” Later, when they have progressed and acquired some precise knowledge, she must go back and correct that intitial necessary fatuity.
We sometimes see this in the introduction to books, so it could also be considered a literary technique.
What is the name of this pedagogical or literary technique? Anyone?
