A reading club wanted to know whether students were becoming more independent readers. It first counted how many pages each student completed. The number was easy to compare, but it hid a difference between fast guessing and careful correction. The club added a delayed check. After two days, students received a new passage on a different topic and explained why one tempting option was wrong. Some students who had completed many pages could not recover the evidence without seeing their notes. Others read fewer pages but could state the claim, locate its limit, and reject an exaggerated choice. The club therefore began tracking recovery as well as volume. A successful week did not require perfect scores. It required a shorter delay before finding evidence again and fewer hints during the new passage. The measure helped teachers choose a common lesson while assigning different follow-up tasks.
