Assessing the Depth of Student-to-Student Talk
In small-group work, it’s not just who is talking—it’s how students are talking to one another that matters. Step 2 focuses on the nature and depth of student-to-student discourse.
High-quality mathematical discourse goes beyond sharing answers. It involves students explaining their thinking, listening to and questioning one another, and critiquing and building on their peers’ reasoning. These actions are essential for positioning students as active doers of mathematics.
Use the Discourse Quality tool to help you assess current talk by identifying and tracking eight types of question–response (QR) pairs*, organized along a continuum of increasing sophistication from logistical exchanges to critiques and justifications.
Eight Question-Response (QR) Pairs
Initial Student Talk
A asks B a practical question ➡️ B answers A’s question
A asks B a question about previously learned content ➡️ B answers A’s question
Moving Talk Towards Student Explanations
A asks B to show work ➡️ B shows own work
A asks B to explain work ➡️ B explains own work
Talk Focused on Student Explanations
A asks B to evaluate work ➡️ B evaluates A’s work
A criticizes B’s work ➡️ B justifies own work
A rejects B’s justification ➡️ B reconstructs own work
A suggests a strategy to the group ➡️ The group tries the strategy
