q2 i? Instructing was positive in coding but negative in writing, whereas modelling was approximately null in coding but strongly positive in writing. → Chen 2026

Chen, Z., Li, H., Xiao, Z., Qu, H., & Xie, X. (2026). Informal learning emerges in everyday human–LLM interaction. arXiv. https://arxiv.org/abs/2607.17643 doi:10.48550/arxiv.2607.17643

Task-stratified support-form contrasts from Results Section 2.4 (Fig. 4b). The article interprets this crossover as two task-specific routes: "testing an instructed procedure in coding and adapting a modelled exemplar in writing".

"Instructing was positively associated with constructive engagement in coding but negatively associated in writing, whereas modelling was approximately null in coding but strongly positive in writing."

Discussion¶

Related Claims¶

• Constructive engagement is ecologically organized: amplified by explicit learning-oriented framing, higher in coding than writing, and more visible in sustained exchanges — related
• Coding-oriented conversations show higher cognitive and constructive engagement than writing-oriented conversations across all three corpora — related
• Adjacent-turn support–engagement coupling is state- and form-dependent: explaining predicts constructive follow-up after all prior states, while feedback's positive association concentrates after prior passive turns — related
• Scaffolded assistant support marks richer constructive participation at the conversation level across all six task settings — 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
