I'm a bit skeptical of saying that the teacher only asked questions and didn't "tell" the students anything. Many of the questions were prefaced with statements and many included new information that was worked into the wording of the question. This was an impressive and well thought out teaching session. And while it was punctuated with constant questions and answers from the students, it definitely was not "only" questions.
