There is a great difference between asking effective questions - questions that promote learning, and asking ineffective questions - questions that do not. The intended purpose is to ask questions that encourage the learner's active participation in thinking through the problem and finding a solution, without having to rely on the instructor to provide answers. This means we should activate what the learner knows in active, critical thinking and problem-solving. We should promote reflection on the issues, the role of society and self in addressing those issues, and the questions inevitably raised by any issue that is not well-settled. This Guide offers a "formula" for crafting effective questions that do just that.
