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? On most questions, both SME and student ratings of instructor voice were significantly higher for human TA responses than for AI responses. → M. Said Doğru & Emily K. Faulconer 2026
q2 i? On most questions, both SME and student ratings showed human TAs demonstrated a more substantial understanding of the student than AI responses. → M. Said Doğru & Emily K. Faulconer 2026 (2)
q2 i? On most questions, both SME and student ratings showed human TAs demonstrated stronger helpfulness than AI responses. → M. Said Doğru & Emily K. Faulconer 2026 (3)
Evidence¶

M. Said Doğru & Emily K. Faulconer. (2026). ChatGPT as a Virtual Laboratory Teaching Assistant in Undergraduate Biology. Research in Science Education. https://doi.org/10.1007/s11165-025-10271-z
q2 · i? · causal · r1
Per-question t-tests following a single-factor ANOVA comparing SME and learner ratings of the 'voice' component for AI- versus human-authored responses. Most questions differed significantly, "with human TAs demonstrating stronger instructor voice for these questions".
"Most questions showed significant differences in instructor voice rating by both instructors and students, with human TAs demonstrating stronger instructor voice for these questions."

q2 · i? · causal · r1
Per-question t-tests on the 'understanding' component of teaching effectiveness, rated by SMEs and students for AI- versus human-authored responses. Most questions differed significantly, "with human TAs demonstrating a more substantial understanding".
"Most questions showed significant differences in the effectiveness of understanding, rated by both SMEs and students, with human TAs demonstrating a more substantial understanding."
