Step 4: Students Prioritize Their Questions. The teacher, with the lesson plan in mind, offers criteria or guidelines for the selection of priority questions. In an introduction to a unit, the instruction may be, “Choose the three questions you most want to explore further.” When designing a science experiment, it may be, “Choose three testable questions.” An essay related to a work of fiction may require that students select “three questions related to the key themes we’ve identified in this piece.” During this phase, students move from thinking divergently to thinking convergently, zero in on the locus of their inquiry, and plan concrete action steps for getting information they need to complete the lesson or task.
