Subclaims¶

q2 i? Early modules provided explicit guidance while later modules asked teachers to justify and generalize without hints, which teachers experienced as a coach fading away. → Ali Bicer 2026

q2 · i? · qualitative · r3

Interview data on the module progression; teachers described a "live progression" from guided prompts early to independent justification and generalization in later modules, supporting CK engagement.

"Teacher F explained, "At the start, AI held my hand a bit, but by Module 8, it asked me to justify and generalize without hints. It was like having a coach fade away.""
