Subclaims¶

q2 i? In Study 1, scaffold precision was low: in approximately two-thirds of cases the chatbot provided more scaffold types than were asked. → Hyoungwook Jin 2026 q2 i? Programmatically adjusting the system prompt with classified question scope substantially improved scaffold alignment to above .60 for Study 2. → Hyoungwook Jin 2026 (2)

q2 · i? · causal · r2

Technical evaluation of help-response alignment (coverage and precision) of the GPT-5.4-mini chatbot used in Study 1, using a human-annotated benchmark of 201, 142, and 165 chatbot responses across tasks. Total scaffold precision was .310 versus coverage .733.

"In particular, scaffold pre- cision was low: in approximately two-thirds of cases, the chatbot provided more scaffold types than were asked."

For Study 2, the chatbot was supplied with the classified knowledge component and scaffold type of each student question and the system prompt was programmatically adjusted; Table 7 shows Study 2 total scaffold precision of .607 versus .310 in Study 1.

"This approach substantially improved scaffold alignment to above .60, indicating that students would receive targeted help in most cases."

Discussion¶

Related Claims¶

• Students rarely formulated questions specifying both knowledge component and scaffold type during chatbot problem-solving — related
• Students' questions shift from broad to specific during Socratic AI tutoring, from about 10–15% specific in the first turn to all students asking specific questions by the final turn — related
• Teachers sought to preserve student thinking and authorship by bounding chatbot answer-giving and maintaining teacher control over scope — a broader claim this one bears on
• Direct student requests for answers significantly increased the AI's provision of direct answers (26.1% vs. 12.5% baseline; r = 0.14), though the AI maintained scaffolding in most cases — related
• Middle school teachers envisioned AI chatbots as adaptive instructional scaffolds providing differentiated support responsive to students' varying needs — related
