In the present study, we tested the effectiveness of three learning strategies (self‐explanation, learning by teaching and passive viewing) used by students who were learning from video lectures. Effectiveness was measured not only with traditional measures, but also with electroencephalography (EEG). Using a within‐subjects design, 26 university students viewed three sets of short lectures, each presenting a different set of English vocabulary words and were asked to use a different learning strategy for each set of lectures. Participants’ EEG signals were assessed while watching the videos; learning experience (self‐reported motivation and engagement) and learning performance (vocabulary recall test score) were assessed after watching the videos. Repeated measures ANOVAs showed that the self‐explaining and teaching strategies were more beneficial than the passive viewing strategy, as indicated by higher EEG theta and alpha band power, a more positive learning experience (higher motivation and engagement) and better learning performance. However, whereas the teaching strategy elicited greater neural oscillations related to working memory and attention compared to the self‐explanation strategy, the two groups did not differ on self‐reported learning experience or learning performance. Our findings are discussed in terms of potential application in courses using video lectures and in terms of their heuristic value for future research on the neural processes that differentiate learning strategies.

通过向自己和同伴解释学习来提高学习者在观看视频讲座时的theta和alpha振荡

在本研究中,我们测试了从视频讲座中学习的学生使用的三种学习策略(自我解释,通过教学学习和被动观看)的有效性。有效性不仅可以通过传统方法来衡量,还可以通过脑电图(EEG)来衡量。使用受试者内部设计,有26名大学生观看了三组简短的讲座,每组呈现不同的英语词汇,并被要求为每组讲座使用不同的学习策略。观看视频时评估参与者的脑电信号;观看视频后,评估学习经验(自我报告的动机和参与度)和学习表现(词汇回忆测验分数)。重复测量的方差分析表明,自我解释和教学策略比被动观看策略更有利,这表现为更高的EEG theta和α波段能力,更积极的学习体验(更高的动机和参与度)和更好的学习表现。然而,尽管与自我解释策略相比,教学策略在工作记忆和注意力方面引起了更大的神经振荡,但两组在自我报告的学习经历或学习表现上并没有差异。我们的发现将根据视频讲座在课程中的潜在应用以及它们对启发性学习方法的价值进行讨论,这些价值对于将来区分学习策略的神经过程的研究具有重要意义。更积极的学习体验(更高的动机和参与度)和更好的学习成绩。然而,尽管与自我解释策略相比,教学策略在工作记忆和注意力方面引起了更大的神经振荡,但两组在自我报告的学习经历或学习表现上并没有差异。我们的发现将根据视频讲座在课程中的潜在应用以及它们对启发性学习方法的价值进行讨论,这些价值对于将来区分学习策略的神经过程的研究具有重要意义。更积极的学习体验(更高的动机和参与度)和更好的学习成绩。然而,尽管与自我解释策略相比,教学策略在工作记忆和注意力方面引起了更大的神经振荡,但两组在自我报告的学习经历或学习表现上并没有差异。我们的发现将根据视频讲座在课程中的潜在应用以及它们对启发性学习方法的价值进行讨论,这些价值对于将来区分学习策略的神经过程的研究具有重要意义。两组在自我报告的学习经历或学习表现上没有差异。我们的发现将根据视频讲座在课程中的潜在应用以及它们对启发性学习方法的价值进行讨论,这些价值对于将来区分学习策略的神经过程的研究具有重要意义。两组在自我报告的学习经历或学习表现上没有差异。我们的发现将根据视频讲座在课程中的潜在应用以及它们对启发性学习方法的价值进行讨论,这些价值对于将来区分学习策略的神经过程的研究具有重要意义。
