When students explain their thinking process aloud, they recognize the strategies they use and solidify their understanding. Think-alouds, or self-explanations, require students to reflect on the details of a problem, the steps needed to solve it, and the mathematical reasoning behind those decisions. They can also be used as formative assessment to monitor students' understanding and address any misconceptions. Research cautions that this strategy is most effective when students are prompted with specific protocols or questions, and that prompts should be carefully aligned with target learning outcomes so students avoid reinforcing incorrect approaches or choices.
