美国学者埃德加·戴尔1946年提出了“学习金字塔”理论,以语言学习为例,学习者在两周以后还记得的学习内容,会因为不同的学习方式而有很大的差异。在初次学习两个星期后:阅读能够记住学习内容的10%;聆听能够记住学习内容的20%;看图能够记住30%;看影像,看展览,看演示,现场观摩能够记住50%;参与讨论,发言能够记住70%;作报告,给别人讲,亲身体验,动手做能够记住90%。埃德加·戴尔提出,学习效果在30%以下的几 American scholar Edgar Dale put forward the theory of “learning pyramid” in 1946. Taking language learning as an example, the content of learning that learners remember after two weeks will vary greatly according to different learning styles. After two weeks of first-time study: reading can remember 10% of learning content; listening can remember about 20% of learning content; reading can remember 30%; watching images, watching exhibitions, watching presentations, 50%; to participate in discussions, speaking to remember 70%; for reporting, to others, to experience, hands-on to remember 90%. Edgar Dell proposed that the learning effect is below 30%
