q2 i? Explaining predicted constructive follow-up after prior constructive, active and passive user turns (ORs 1.72, 2.13 and 2.88), while feedback's positive association concentrated after prior passive turns. → Chen 2026

Integrated logistic regressions with prior-state×support-form interactions from Results Section 2.5; the scaffolding block improved fit (LRχ2(7)=1339.6, p<.001) and interactions improved fit further (LRχ2(18)=297.3, p<.001).

"Explaining provided the more stable adjacent-turn signal, predicting constructive follow-up after prior constructive, active and passive user turns (ORs 1.72, 2.13 and 2.88, respectively; allp < .001)"

Related Claims¶

• Scaffolded assistant support marks richer constructive participation at the conversation level across all six task settings — the general claim this finding bears on, with the studies behind it
• Constructive learning beats active and passive learning — a broader claim this one bears on
• Generative (Constructive) engagement by young children produces better learning than attentive (Passive) engagement — a broader claim this one bears on
• Learning-oriented engagement is recurrent but selective in everyday human–LLM conversations, with cognitive engagement in 31.9% and constructive engagement in 4.9% of user turns — related
• Support form differentiates the scaffolding–engagement association: feedback and explaining align most with constructive engagement, with a task-ecology crossover between instructing and modelling — related
• Constructive engagement is ecologically organized: amplified by explicit learning-oriented framing, higher in coding than writing, and more visible in sustained exchanges — related
