When you ask a question in class that you would like students to answer:
1. Wait 15 seconds before you call on anyone – gives more people a chance to think of an answer.
2. If no one has volunteered after 30 seconds, try rephrasing the question or asking students what they need to know to answer the question.
3. Try to call on different people throughout a class. You could say, I want to hear from someone who has not yet participated.
4. Give verbal and nonverbal feedback to students who have particlpated-praise for good answers, for non-helpful answers you might thank the person for volunteering and. ask for more responses.
