Subclaims¶

q2 i? The most common divergence was less specific reasoning grounded in lesson contexts, evidence, and mechanisms (60.54% of ideas). → Nguyen 2026 q2 i? LLM misconceptions were less developmentally appropriate (17.69%), LLMs used more technical vocabulary (35.71%), showed fewer uncertainty markers (14.63%), and produced more analogies (7.48%) than lesson ideas. → Nguyen 2026 (2)

q2 · i? · design · r2

Qualitative comparison of LLM-generated and lesson ideas, with GPT-5-assisted summaries verified by two researchers through two rounds of iterative coding. In an ecosystems lesson, LLMs gave generic ideas like "careless human activities" where lesson ideas cited local dams and gardening.

"Although the generated ideas generally overlapped with the targeted concepts in the lesson ideas, we observed that LLM ideas showed less specific reasoning grounded in lesson contexts, evidence, and mechanisms (60.54%; see Table 2 for range across LLMs)."

Table 2 reports divergence-theme percentages across LLMs (n = 294 clusters): broad reasoning 60.54%, misconception substance 17.69%, technical vocabulary 35.71%, less uncertainty 14.63%, analogy use 7.48%. Lesson ideas showed markers like "it seems like", "maybe" more often.

"First, some LLMs (e.g., GPT-4o, GPT-5-mini) produced longer sentences with more technical vocabulary than the lesson ideas (35.71%)."
