Short answer questions (SAQ) are open-ended questions that require students to write out an answer rather than select from options. They are used to assess basic knowledge and understanding. SAQ should use precise language and focus on important content. They are structured to test recall of specific facts and knowledge through brief, targeted answers. SAQ have advantages like being easy to score, improving reliability, and allowing for better content coverage than essays. However, they are not suitable for measuring complex learning or analytical reasoning abilities. Examples of good and bad SAQ structures are provided.
