Dialogic Teaching Move Generator
Generate follow-up teaching moves that extend student thinking after a specific classroom response. Use when a student says something worth exploring and the teacher wants to deepen the dialogue.
What it does
Takes a specific student response during classroom dialogue and generates high-quality teacher follow-up moves — the exact words a teacher could say next to deepen thinking, extend reasoning, invite other voices, or challenge assumptions. Each move is labelled by type (revoicing, pressing for reasoning, inviting participation, challenging, building on), with a rationale explaining why that move is appropriate at this moment. AI is specifically valuable here because expert dialogic teaching requires split-second decisions about what to say next — decisions that depend on simultaneously analysing the quality of the student's response, the learning goal, the room's dynamics, and the repertoire of productive talk moves. Even experienced teachers default to evaluating ("Good answer!") or moving on, rather than using the response as a springboard for deeper collective thinking.
The evidence behind it
Mercer (2000) introduced the concept of "interthinking" — the idea that dialogue is not just communication but a tool for thinking together. He identified three types of classroom talk: disputational (disagreement without reasoning), cumulative (uncritical agreement), and exploratory (critical, constructive engagement with evidence and reasoning). Only exploratory talk consistently produces learning gains. Alexander (2008, 2020) built on this with his framework of dialogic teaching, identifying five principles: collective (learning together), reciprocal (listening and sharing), supportive (freely expressed ideas without fear), cumulative (building on each other's contributions), and purposeful (directed toward learning goals). Michaels et al. (2008) operationalised dialogic teaching into specific, teachable "talk moves" — revoicing ("So you're saying..."), pressing for reasoning ("What makes you think that?"), inviting others ("Who can add to what she said?"), and challenging ("Does anyone disagree?"). Resnick et al. (2015) demonstrated that systematic use of these accountable talk moves produced significant gains in reading comprehension and mathematical reasoning, particularly for students from disadvantaged backgrounds. Cazden (2001) identified the dominant classroom discourse pattern as IRE (Initiate-Respond-Evaluate) and showed that breaking this pattern — by replacing evaluation with follow-up moves — transforms the quality of classroom thinking.

How to use it in your lesson
For the best results with EvidenceLesson, give it:
- student_response — The specific student response the teacher needs to follow up on
- learning_goal — What the teacher wants students to understand or be able to do
- subject_context — Subject area and topic being discussed
- student_level (optional) — Age/year group and verbal confidence level
- student_profiles (optional) — From context engine: language levels, confidence with discussion, cultural factors
- response_quality (optional) — Teacher's assessment of the response — correct, partially correct, incorrect, unclear, or superficial
- classroom_context (optional) — Whole class, small group, or one-to-one; stage of the lesson
Known limitations
- The quality of the output depends entirely on the accuracy of the student response provided. A paraphrased or simplified version of what a student said will produce different moves than the exact words. Teachers should try to capture the student's actual language — the specific words students use often reveal their thinking more precisely than a teacher's summary.
- Dialogic moves require a classroom culture that supports them. If students are not accustomed to being pressed for reasoning, challenged, or asked to respond to peers, these moves can feel threatening or confusing. Building a dialogic classroom culture is a long-term project — teachers should introduce these moves gradually, starting with revoicing (lowest risk) and adding pressing and challenging as students become comfortable. This skill generates the moves but cannot build the culture.
- The generator cannot read the room. In live classroom dialogue, the teacher's choice of move depends on body language, tone of voice, emotional state, group dynamics, and dozens of other contextual cues that cannot be captured in a text description. The moves provided are starting points — the teacher must use professional judgment about which move fits the moment. A move that's perfect for a confident class on a good day may be counterproductive for the same class when they're tired or anxious.
