检索练习：为什么先回忆，比重读更能暴露缺口？

概念词条 CONCEPT ENTRIES

「检索练习」（retrieval practice）不是把笔记再看一遍，而是合上材料后，先从记忆里取回答案：默写、闪卡、练习题或自测都算。它替代的是「再读几遍，直到看起来很熟」这段描述，直接把目标改成「没有提示时能不能取出来」。1
与重读相比，优势更常出现在延迟保持，而不是刚学完时的熟悉感；答错后对照答案修正，效果通常更好。2
直接调用时，让 AI 用「检索练习」为这段材料设计 3 道先答后看的问题，并给出正确答案、解释与常见误区。边界要留住：做过一次不会自动生效；题目难度、反馈、投入程度和延迟时间都会影响结果——在线众包样本中也曾复现不出显著优势。3
