I agree. Often times, inquiry-based learning involves more discipline, particularly self imposed discipline by the students.
But I also think the kind of discipline I alluded to about the Catholic school piece is important as well. Listening to lectures, taking notes, being actively involved in something which is not totally engrossing shows a very high level of self discipline.
