That sounds more like a problem with incoming student's expectations than with the teaching method. Almost every interesting (i.e., sufficiently complex) subject isn't arranged in a pedagogical hierarchy. You can't explain history from the first day, because you'd have to explain where that knowledge came from. You can't explain math without pushing things for later because students are not prepared for generality on day 1. You can't explain human biology by describing various cells. Etc.. If a student is going to 'check out' because they didn't get a question answered, then they're probably just going to fail. See your teacher after class, ask a friend, look it up online... If are a 'curious student' doesn't see these very obvious methods of satisfying their curiosity, then they're probably not worth a teacher's efforts.
