Teaching materials save the product and lose the reasoning
Reusable teaching materials can keep the visible lesson while dropping the reasoning that made it work. The paper's warning matters for AI-assisted curriculum work: saving the artifact is not enough if the next teacher cannot see why key choices were made.
What the source reports
Yi Ching Chou and coauthors ask what teaching materials save over time. Reusable work often keeps the final product. It may lose the thinking that shaped it. That thinking includes choices about how and why to teach a lesson. The gap matters when another teacher gets the file. That teacher may not know which parts were key. They may also lack the facts needed to adapt it well. The paper treats this as a design problem for future materials. The digest supports the split between a saved product and lost reasoning. It does not give the setting, sample, method, or measured effects. It does not prove one note system will fix the gap.
