Although examples can be structured to emphasize diagnostic features of concepts, novice learners tend to focus on irrelevant surface features and struggle to encode deeper structures. Experiment 1 examined whether pretesting-answering questions about content before it is studied-could enhance learners' noticing of diagnostic features, making them easier to process during subsequent study. Participants studied statistical concepts with examples that emphasized surface details or deep structure, and then classified new examples of these concepts. Studying examples that emphasized deep structure increased classification performance compared to examples that emphasized surface details. Moreover, taking pretests prior to studying the examples increased classification performance and eliminated differential benefits of studying structure versus surface examples. Experiment 2 examined whether pretesting serves a role beyond directing attention. After studying different statistical concepts with only surface-emphasizing examples, classification performance was better when participants actually took pretests compared to being given the correct responses. It is the generative aspect of pretesting, beyond attention directing, that improves conceptual learning among novice learners. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
虽然可以通过构造示例来强调概念的诊断特征,但新手学习者往往会关注不相关的表面特征,并努力对深层结构进行编码。实验 1 检验了在学习内容之前进行预先测试(回答有关内容的问题)是否可以增强学习者对诊断特征的注意,从而使他们在随后的学习中更容易处理这些特征。参与者用强调表面细节或深层结构的示例学习统计概念,然后对这些概念的新示例进行分类。与强调表面细节的示例相比,强调深层结构的示例提高了分类表现。此外,在学习示例之前进行预测试可以提高分类表现,并且消除了学习结构与表面示例之间的差异收益。实验 2 检验了预测试是否除了引导注意力之外还有其他作用。在仅使用强调表面特征的示例学习不同的统计概念后,与给参与者正确答案相比,当他们实际进行预测试时,分类表现更好。正是预测试的生成方面,而不仅仅是注意力引导,提高了新手学习者的概念学习能力。(PsycInfo 数据库记录(c)2021 APA,保留所有权利)。
