This document discusses using the SOLO (Structure of the Observed Learning Outcome) taxonomy to develop questions that require different levels of cognitive demand from students. The SOLO taxonomy categorizes questions and responses into five levels - prestructural, unistructural, multistructural, relational, and extended abstract - with each level building on the previous one and requiring deeper thinking. The document provides examples of questions at each level and guidance for teachers on developing questions that target higher levels of thinking.
