Description¶

The article replaces a generic numbered problem-chain output format with three distinct chain types that structure classroom questioning across a lesson. Context-based chains introduce new knowledge through scenarios, trap-based chains pose medium- to high-difficulty questions that provoke critical thinking and productive failure, and summary-based chains support review and further interest. The authors report that "this subdivision approach enhances the LLM’s understanding of the teaching process, progressing from basic to advanced levels, and leads to better outcomes when designing andimproving teaching plans."

Design Implications¶

Context¶

Requirements¶

Prompts must include the lesson's knowledge points, instructional objectives, and teaching priority and challenge, with examples supplied for each chain type

Constraints¶

Trap-based problem chains score slightly lower in usability than the other two types, indicating LLM limits in designing deep and challenging questions

Target Learners¶

high school mathematics students

Learning Goals¶

gradual understanding and mastery of mathematical concepts through sequenced problem chains
