Useful friction before revision
1Students who repeatedly reread polished notes often mistake recognition for mastery. Recognition feels smooth because every connection has already been supplied. Yet that smoothness says little about whether the learner can rebuild the idea without help.
2A retrieval attempt before rereading creates useful friction. When the attempt stops at a missing link, the location of that pause identifies the exact weakness. The student can then inspect the relevant sentence, name the relationship that was missed, and revise only that part of the explanation.
3An instructor should therefore resist erasing the difficulty by giving a complete answer immediately. A short prompt can direct attention to evidence while leaving the learner responsible for the connection. Targeted revision may look smaller than rewriting an entire page, but it preserves the learner's reasoning and makes the next attempt more informative.
4After revising, the student should explain why the new wording is supported by the text. This final explanation links objective judgment to a written response: the evidence that eliminated a wrong choice also protects the meaning of the student's own sentence.
