Overview
Cold Call is a questioning technique where the teacher calls on students regardless of whether they have raised their hands. The selection is unpredictable, which keeps all students accountable and engaged because anyone could be called at any time.
Educational Purpose
When teachers only call on volunteers, the same 3-5 students answer every question. The rest tune out. Cold Call ensures every student is accountable for thinking because they could be called on at any moment.
Educational Psychology Behind It
Research on engagement shows that unpredictable accountability increases on-task behavior. Combined with Wait Time (pause before calling), Cold Call gives all students time to think before being called.
Why It Works
Research on engagement shows that unpredictable accountability increases on-task behavior. Combined with Wait Time (pause before calling), Cold Call gives all students time to think before being called.
When to Use It
Use in any subject, Grade 4 and up. Must be paired with a safe, supportive culture -- not 'gotcha' questioning. Use it consistently, not as a punishment. Pair with No Opt-Out (if a student says 'I don't know,' return to them after another student answers).
When NOT to Use It
Avoid Cold Call as punishment or 'gotcha.' Avoid calling only on struggling students. Do not Cold Call before establishing a safe classroom culture. Do not accept 'I don't know' as a final answer -- use No Opt-Out.

Step-by-Step Classroom Guide
- 1Ask a question clearly.
- 2Wait 3-5 seconds (Wait Time 1). Let students think.
- 3Call on a student who has not raised their hand. Use a random system or rotate.
- 4If the student answers, respond and move on.
- 5If the student says 'I don't know,' say: 'I'll come back to you.' Call another student. Then return to the first student: 'Now what do you think?' (No Opt-Out).
- 6Keep the tone warm and supportive, not punitive.
Classroom Scenario
Mr. Villanueva uses Cold Call in Grade 9 Social Studies. He asks: 'What was the main cause of the Philippine-American War?' He waits 5 seconds, then calls on a student who hasn't raised her hand. She says: 'I'm not sure.' He says: 'I'll come back to you.' He calls on another student who says: 'It was about independence and the US wanting to control the Philippines.' He returns to the first student: 'So what was the main cause?' She says: 'The US wanted to control the Philippines, and Filipinos wanted independence.' The No Opt-Out ensures she is accountable and successful. Over time, she starts raising her hand.

Variations & Adaptations
Adjust the complexity of questions, wait time duration, and accountability structures based on students' experience with questioning.

This strategy requires no technology. If desired, enhance with digital tools such as Google Docs for collaborative writing or Padlet for sharing responses.
Assessment Ideas
Assess through observation of participation, quality of questioning, and formative checks such as exit tickets or quick writes.
