Is comprehension the same whether a person reads a text onscreen or on paper? And are listening to and viewing content as effective as reading the written word when covering the same material? The answers to both questions are often "no. " The reasons relate to a variety of factors, including reduced concentration, an entertainment mindset(心态)and a tendency to multitask while consuming digital content.
When reading texts of several hundred words or more, learning is generally more successful when it's on paper than onscreen. A large amount of research confirms this finding. The benefits of print reading particularly shine through when experimenters move from posing simple tasks-like identifying the main idea in a reading passage-to ones that require mental abstraction-such as drawing inferences from a text.
The differences between print and digital reading results are partly related to paper's physical properties. With paper, there is a literal laying on of hands, along with the visual geography of distinct pages. People often link their memory of what they've read to how far into the book it was or where it was on the page.
But equally important is the mental aspect. Reading researchers have proposed a theory called "shallowing hypothesis(假说). " According to this theory, people approach digital texts with a mindset suited to social media, which are often not so serious, and devote less mental effort than when they are reading print
Audio(音频)and video can feel more engaging than text, and so university teachers increasingly tum to these technologies -say, assigning an online talk instead of an article by the same person. However, psychologists have demonstrated that when adults read news stories, they remember more of the content than if they listen to or view identical pieces
Digital texts, audio and video all have educational roles, especially when providing resources not available in print. However, for maximizing leaning where mental focus and reflection are called for, educators shouldn't assume all media are the same, even when they contain identical words.
