Abstract: There is growing recognition that AI technologies can, and should, support collaborative learning. To provide this support, we need models of collaborative talk that reflect the ways in which learners interact. Great progress has been made in modeling dialogue for high school and college-age learners, but the dialogue processes that characterize collaborative talk between elementary learner dyads are not currently well understood. This paper reports on a study with elementary school learners (4th and 5th grade, ages 9–11 years old) coded collaboratively in dyads. We recorded dialogue from 22 elementary school learner dyads, covering 7594 total utterances. We labeled this corpus manually with dialogue acts and then induced a hidden Markov model to identify the underlying dialogue states and the transitions between these states. The model identified six distinct hidden states which we interpret as Social Dialogue, Confusion, Frustrated Coordination, Exploratory Talk, Directive & Disagreement, and Disagreement & Self-Explanation. The HMM revealed that when students entered into a productive exploratory talk state, the primary way they transitioned out of this state is when they became confused or reached an impasse. When this occurred, the learners then moved into states of disputation and conflict before re-entering the Exploratory Talk state. These findings can inform the design of AI agents who support young learners’ collaborative talk and help agents determine when students are conflicting rather than collaborating.
