Use response devices. In the larger first year classes you can use socratic mobile phone quizzes or other technology to get responses from the whole class. Also you can pass around the microphone to hear their answers to the questions. But it’s often the extroverts who will volunteer to do that. Sometimes it can give you the wrong impression of the class, because the ones who are responding are the ones that understand it. Whereas the ones who don’t understand it are keeping quiet. So the response devices are quite a good way of just trying to get a better picture of the whole class.
