A probe is a question that immediately follows a student’s response. (p.310)

  1. Eliciting probes: encourage students to show more of what they know
  • to have students rephrase or reword a response (T: checking the response)

(e.g. “Can you try to explain that in another way?”)

2. Soliciting probes: ask for new information

  • to use the probe to push the student’s response to a more complex level

(e.g. “Now that you have taken 5 squared, how can you extend the same idea to find 5 cubed?”)

3. Redirecting probes

  • to restructure the students’ response in a more productive direction

Examples of talk in action in Mathematics

“Talk Moves “

Five Productive Talk Moves

-   Move 1: Revoicing (“So you’re saying that it’s an odd number?”)

  • to repeat some or all of what students has said, then
  • to ask students to respond and verify whether or not the teacher’s revoicing is correct

(Revoicing provides more “thinking space”)

Move 2: Repeating: asking students to restate someone else’s reasoning (“Can you repeat what he just said in your own words?”)

  • to ask one student to repeat or rephrase what another student has said, and then immediately following up with the first student

-   Move 3: Reasoning: asking students to apply their own reasoning to someone else’s responding (“Do you agree or disagree and why?”)

-   Move 4: Adding on: prompting students for further participation (“Wound someone like to add something more to this?”)

-   Move 5: Waiting: using wait time (“Take your time… we’ll wait…”)
