This post on Edutopia talks about the importance of questions in learning. This is so true – even in academic writing (IMHO). As a Principal I often talked to teachers about this skill – for themselves and for students. Questions drive learning. An excerpt.
Lessons, units, and topics are more motivating when they begin with a question whose answer students want to know. Not only do great questions generate interest, they also answer the question that so many students wonder about: “Why do I have to learn this?” Finally, great questions increase cognitive organization of the content by framing it into a meaningful answer to the opening question.
