A question can be more than a means to elicit information. When students answer questions, they begin to understand new information, construct ideas, apply knowledge, and demonstrate understanding. When they ask questions, they begin to form mental models; explore connections among ideas; consider di erent perspectives; elaborate, enrich, and broaden their understanding; and transfer and generalize their knowledge to new situations. This 8-page quick reference guide provides reseaerch-based insights and strategies for helping teachers craft questions that offer appropriate cognitive challenge, spark curiosity, match stages of learning, and support a community of student learners.
