What is Teacher Talk Time?

Understanding the balance of classroom discourse is key to effective teaching.

Teacher Talk Time (TTT) is the amount of time a teacher spends talking during a lesson, compared to Student Talk Time (STT) - the time students spend speaking.

Research consistently shows that lessons with more student talk time lead to better learning outcomes. When students articulate their thinking, ask questions, and discuss with peers, they engage more deeply with the material.

But here's the challenge: most teachers significantly underestimate how much they talk. Without objective measurement, it's nearly impossible to know your actual talk ratio.

Individual student talk time is positively correlated with outcomes like test scores. The more opportunities students have to verbalise their thinking, the better they learn.

Why Teacher Talk Time Matters

The balance of classroom discourse affects everything from engagement to achievement

Deeper Understanding

When students explain concepts in their own words, they process information more deeply and retain it longer.

Better Engagement

Students who participate actively are more engaged. Passive listening leads to minds wandering and disengagement.

Formative Assessment

When students talk, you hear their thinking and can identify misconceptions before they become embedded.

Language Development

Especially important in language learning - students need to practice speaking, not just listening.

Equity in Participation

Some students naturally dominate discussions. Understanding participation patterns helps ensure all voices are heard.

Teacher Awareness

Most teachers are surprised by their actual TTT. Objective data is the first step to intentional improvement.
