Teachers play an important role in facilitating student participation in several ways: 1) They can encourage participation by asking open-ended questions that spark discussion and close-ended questions that elicit longer answers from students. 2) Teachers should use techniques like pausing after asking a question to allow students time to respond, and asking another student for help if no one answers initially. 3) Framing participation as a collective responsibility of the whole class, rather than just individuals, can also help facilitate discussion where students build on each other's responses.
