Effective questioning can scaffold learning and probe understanding. It
creates teachable moments for teachers to correct a misconception, reinforce a point
or expand on an idea. The questions can be open-ended to encourage students to
consider alternative approaches. Sufficient wait-time is necessary so that students
can formulate their thoughts, communicate and share their ideas, and hear the ideas
of others. In the process, students learn to articulate their thinking and deepen their
understanding, and develop confidence in talking about mathematics and using it.
Teachers can assess students’ thinking and understanding, and provide useful
feedback to improve their learning.
