meaning of "not communicative"
hi everyone, quick question. normally i receive 5s on my lessons, but someone gave me a 3 and said "not communicative" even though i asked follow-up questions, he seemed engaged in the lesson, and said there was nothing left to go over that we didn't get to before when we asked. he also told me he prefers i paraphrase after we go over each question.
i think it's quite obnoxious when students say the lesson was fine then give a low rating. it also gives me minor anxiety that these ratings will harm my booking rate, which has been steady so far. i asked follow up questions, checked in, etc - so i am wondering what "not communicative" means. am i missing something here? thanks!
