Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i2 Human-human dialogues were significantly longer and contained nearly three times as many turns as AI dialogues, while participants produced significantly longer turns with more words per turn with the AI. → Russell Scheinberg 2026

q3 · i2 · causal · r2
Paired comparison of 78 learners' human-human vs. AI dialogues in a counterbalanced within-participant design. Human dialogues were longer (d=−0.44) with nearly three times as many turns (d=−1.35); AI turns were longer (d=0.39) with more "words per turn (M= 18.0 vs. 12.1, d= 0.51, p < .001)".
"Human-human dialogues were significantly longer (M= 764 s vs. 608 s,d=−0.44,p < .001) and contained nearly three times as many turns (M= 66.5 vs. 22.2,d=−1.35,p < .001)."
Discussion¶
Related Claims¶
- Turn-taking with an AI partner shows slower responses, reduced learner floor share, and greater within-turn fluency — related
- Excessive dependence on AI may reduce human interaction and dehumanize adult education — related
- Teachers' engagement growth was negotiated through balancing challenges and cognitive load, with some experiences of strain and isolation — related
- Teaching interactions typically conclude within 30 dialogue turns, motivating a 30-turn cap to prevent dead loops — related
- Interactive engagement requires both partners' utterances to be primarily constructive and a sufficient degree of turn taking — related
- Despite longer AI-led sessions, the proportion of student-generated dialogue was markedly and significantly lower with the AI than with the teacher in both grades — related
