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.
q2 i? Student word proportion was significantly lower with the AI for Grade 4 (t(11)=−4.89, p<.001) and Grade 5 (t(6)=−5.62, p=.001), and sentence proportion was drastically lower (Grade 4 t(11)=−6.15, p<.001; Grade 5 t(6)=−8.21, p<.001). → Liao 2026

Liao, C.-Y. (2026). Beyond a single role: Justifying a role-adaptive framework for ai companions through a comparative study in elementary book talk. Education and Information Technologies. https://doi.org/10.1007/s10639-026-13958-6
q2 · i? · causal · r1
Paired-samples t-tests on student-level means from the same within-subjects study (N=19) compared word and sentence contribution proportions across AI-led and teacher-led sessions. In Grade 5, "student contribution was less than a third of that in teacher-led sessions." No effect size printed.
"Student Word Proportion: The percentage of words contributed by students was significantly lower with the AI for both Grade 4 (t(11) = −4.89, p <.001) and Grade 5 ( t(6) = −5.62, p =.001). Student Sentence Proportion: Similarly, the proportion of sentences from students was drastically lower in the AI condition for both Grade 4 (t(11) = −6.15, p <.001) and Grade 5 (t(6) = −8.21, p <.001)."
Discussion¶
Related Claims¶
- In elementary book talk, students spent significantly more time interacting with a fixed-role AI peer than with their homeroom teacher in both grades — related
- For Grade 4 students, the human teacher elicited significantly more utterances than the AI peer in every 4F reflection category, most pronouncedly for Future-oriented talk — related
- Turn-taking with an AI partner shows slower responses, reduced learner floor share, and greater within-turn fluency — related
- Human-human L2 dialogue has more and shorter turns while AI dialogue has fewer, longer turns with more words per turn — related
- For Grade 5 students the AI peer elicited more factual statements but far fewer Feelings utterances than the teacher, with no significant differences in Findings or Future — related
- Talk-time analysis showed the mentor spoke more than the mentee in video-recorded dialogues, with classroom management talk ranging from 3% to 39% of total talk time — related
- Student proportion of words spoken in whole-class talk increased in both dose groups after VSDR — related
- Interactive engagement requires both partners' utterances to be primarily constructive and a sufficient degree of turn taking — related
