Ask everyone, then pick
Hands-up tells you what your keenest five students know. Cold call after thinking time tells you about the room.

Pose the question to everyone, give thinking time (or a jotted answer), then name who answers. The moment students know a question might land on anyone, the whole room does the thinking, not just the volunteers. And the common worry about cold call is unfounded: in classes where it was used frequently, voluntary participation rose over time, with no drop in students' reported comfort (Dallimore, Hertenstein & Platt, 2013).
In practice
- Sequence matters: question, pause, name. Naming first lets everyone else switch off.
- Keep it warm. Cold call is an invitation, not a trap: "Maya, what did you get for the first step?" Specific, answerable, low-stakes.
- If a student can't answer, stay with them: give a hint, or take another answer and come back. "Jon, say it back in your own words." Escaping by silence should be rarer than getting support.
- Mix in pair-share first for harder questions so nobody is answering cold in both senses.
Quick takeaway: volunteers tell you the best case. Cold call tells you the truth.
