Using text and image together can lead to better learning due to the dual-coding theory – that there are two separate parts of our brains to process textual\/verbal vs. visual information. In other words our brain can handle more content if it’s in the form of text AND image; our brain has a limit of how much textual content it can handle and a different limit of the imagery content it can handle. To dive deeper, the act of comprehending and constructing mental models from text undergoes a different neural process than if the stimuli is imagery.<\/p>\n\n\n\n

\u201cstudents usually learn better from words and pictures than from words alone\u201d <\/p>(Schnotz, 2022, p. 92)<\/cite><\/blockquote><\/figure>\n\n\n\n

The popularity of memes is no surprise, as they represent a powerful combination of text and image; an immediate visual understanding and textual context.<\/p>\n\n\n

As you read on, I want you to reflect upon your personal experiences with text and imagery. Think about how each medium influences your learning, how you communicate with friends and family, and how advertising may leverage forms of media.<\/p>\n\n\n\n

Meaningful learning from text and pictures requires a coordinated set of cognitive processes, including the selection of information, organization of information, activation of prior knowledge, and active coherence formation by integrating information from different sources. In the comprehension of written or spoken texts, the learner selects relevant verbal information from words, sentences, and paragraphs as an external source of information. He or she organizes the information, activates related prior knowledge as an internal source of information, and constructs both a coherent propositional representation and a coherent mental model. In the comprehension of visual pictures, the learner selects relevant pictorial information from a drawing, a map, or a graph as an external source of information, organizes the information, activates related prior knowledge as a further source of information, and constructs a coherent mental model complemented by a propositional representation.<\/p>(Schnotz, 2022, p. 91)<\/cite><\/blockquote><\/figure>\n\n\n

It is important to know the strengths and weaknesses of each media so that multimedia compliment instead of undermine one another. There is no optimal media (text nor image) but there is potentially a better choice for what you are communicating. We can frame the differences of image and text as speed vs. depth, appearances vs. analysis, and emotion vs. reason (Yousman, 2015).<\/p>\n\n\n\n

\u201cWhen learners have low prior knowledge, mental model construction from written text can become too difficult. Adding a picture as another source of information can then enhance comprehension, because it offers an additional route for mental model construction.\u201d<\/p>(Schnotz, 2022, p. 91)<\/cite><\/blockquote><\/figure>\n\n\n\n

Text + Image \u2260 Best Learning<\/h2>\n\n\n\n

While text and image recruit different neural pathways, the combination of text and image does not always lead to better learning. In fact, when text and image are used together poorly, it can have a negative effect on learning. Let\u2019s explore each of the principles of Mayer\u2019s Cognitive Theory of Multimedia Learning that may be affected:<\/p>\n\n\n\n

Redundancy Principle:<\/strong> If a learner does not need two information sources, i.e. if they have strong prior knowledge, then offering both image and text provides extraneous cognitive load.<\/p>\n\n\n\n

Coherence and Contiguity:<\/strong> If there is too much time or distance between textual information and visual information then the learner will not easily connect the image with the text.<\/p>\n\n\n\n
