q2 · i? · associational · r1

Stratified examination of AI safeguard-related behaviors by teacher-authored guardrails across pilot conversations. The article reports the rate "dropped from 16.2% to 7.7%, a reduction of 8.5 percentage points"; contextual review found violations typically followed extended scaffolding attempts.

"When teachers included explicit "no direct answers" constraints in their prompts, the AI's answer provision rate dropped from 16.2% to 7.7%, a reduction of 8.5 percentage points."

• Prompt specificity changes AI tutor pedagogy: a no-direct-answer guardrail alone produces uniform questioning, while a detailed guided protocol produces varied, impasse-sensitive responses — related
• 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
