Basic research on human learning and memory has shown that practising retrieval of information (by testing the information) has powerful effects on learning and long-term retention. Repeated testing enhances learning more than repeated reading, which often confers limited benefit beyond that gained from the initial reading of the material. Laboratory research also suggests that students lack metacognitive awareness of the mnemonic benefits of testing. The implication is that in real-world educational settings students may not engage in retrieval practise to enhance learning. To investigate students' real-world study behaviours, we surveyed 177 college students and asked them (1) to list strategies they used when studying (an open-ended free report question) and (2) to choose whether they would reread or practise recall after studying a textbook chapter (a forced report question). The results of both questions point to the same conclusion: A majority of students repeatedly read their notes or textbook (despite the limited benefits of this strategy), but relatively few engage in self-testing or retrieval practise while studying. We propose that many students experience illusions of competence while studying and that these illusions have significant consequences for the strategies students select when they monitor and regulate their own learning.
关于人类学习与记忆的基础研究表明,练习信息检索(通过测试信息)对学习和长期记忆有强大的影响。重复测试比重复阅读更能增强学习效果,重复阅读往往除了从最初阅读材料中获得的益处之外,带来的好处有限。实验室研究还表明,学生缺乏对测试记忆益处的元认知意识。这意味着在现实世界的教育环境中,学生可能不会通过检索练习来增强学习效果。为了调查学生在现实世界中的学习行为,我们对177名大学生进行了调查,要求他们:(1)列出学习时使用的策略(一个开放式自由报告问题);(2)在学习完教科书的一章后,选择是重新阅读还是练习回忆(一个强制报告问题)。两个问题的结果都指向同一个结论:大多数学生反复阅读笔记或教科书(尽管这种策略益处有限),但相对较少的学生在学习时进行自我测试或检索练习。我们认为,许多学生在学习时会产生能力错觉,并且这些错觉对学生在监控和调节自己学习时选择的策略有重大影响。
