What is the purpose of the teacher asking questions like "Can you elaborate?" during a lesson?

The purpose of a teacher asking questions such as "Can you elaborate?" is to prompt students to think more deeply about the material being discussed. This type of question encourages students to expand on their thoughts and insights, fostering an environment of critical thinking. By requiring students to provide more detail, reflect on their understanding, and make connections, the teacher helps them develop analytical skills that are essential for higher-order thinking. This approach also empowers students to take ownership of their learning and articulate their ideas more clearly, which significantly enhances their overall comprehension of the subject matter.
