Postgraduate residencies utilize academic half-days to supplement clinical learning. Spaced repetition reinforces taught content to improve retention. We leveraged spaced repetition in a curriculum companion for a paediatric residency program's half-day. One half-day lecture was chosen weekly for reinforcement (day 0). Participants received 3 key points on day 1 and a multiple-choice question (MCQ) on day 8. On day 29, they received two MCQs to test reinforced and unreinforced content from the same day 0. Thirty-one (79%) residents participated over 17 weeks, but only 14 (36%) completed more than half of the weekly quizzes. Of all quizzes, 37.4% were completed, with an average weekly engagement of 5.5 minutes. Helpfulness to learning was rated as 7.89/10 on a Likert-like scale. Reported barriers were missing related half-days and emails, or limited time. There was no significant difference in performance between reinforced (63.4%, [53.6-73.3]) and unreinforced (65.6%, [53.7-73.2]) questions. Spaced repetition is a proven strategy in learning science, but was not shown to improve performance. Operational barriers likely limited participation and underpowered our analysis, therefore future implementation must consider practical and individual barriers to facilitate success. Our results also illustrate that satisfaction alone is an inadequate marker of success.
研究生住院医师利用半天的学术时间来补充临床学习。间隔重复强化所教授的内容以提高保留率。我们在儿科学住院医师项目的半天课程配套材料中利用了间隔重复。每周选择半天的一次讲座进行强化（第 0 天）。第 1 天，参与者收到 3 个要点，第 8 天收到一个多项选择题（MCQ）。第 29 天，他们收到两个 MCQ 来测试第 0 天强化和未强化的内容。在 17 周内，有 31 名（79%）住院医师参与，但只有 14 名（36%）完成了超过一半的每周测验。在所有测验中，有 37.4%的人完成了测验，平均每周参与时间为 5.5 分钟。在类似于李克特量表的评分中，对学习的帮助程度评分为 7.89/10。报告的障碍包括缺少相关的半天和电子邮件，或时间有限。强化（63.4%，[53.6-73.3]）和未强化（65.6%，[53.7-73.2]）问题之间的表现没有显著差异。间隔重复是学习科学中经过验证的策略，但并未显示出可提高性能。运营障碍可能限制了参与度，并且使我们的分析力度不足，因此未来的实施必须考虑到实际和个人障碍，以促进成功。我们的结果还表明，满意度本身是成功的一个不充分指标。
