The power of pictures
They don’t just look pretty. They can also be a useful means of delivering extensive information to your audience in a concise format.
For example, how would you explain the GFC to your colleagues? Via a thousand words of text, or via one of these infographics:
On the space of one page, these graphics do a good job of explaining the key concepts of a complex and convoluted situation.
The power of pictures has been recognised in educational psychology for a long time.
For example, back in 1996, Richard Mayer and several of his colleagues from the University of California, Santa Barbara studied the effects of a multimedia summary (a sequence of annotated illustrations depicting the steps in a process) on learning how lightning is formed. [Ref]
Through a series of experiments, the researchers found that the students who read a multimedia summary on its own recalled the key explanative information and solved transfer problems as well as or better than the students who read the multimedia summary accompanied by a 600-word passage. Both groups of students performed as well as or better than the students who read the text passage on its own.
I consider these results important because, not only do they support the idea of pictures enhancing learning, but they also suggest that an infographic can achieve similar learning outcomes whether or not it is accompanied by a relatively large amount of text.
The researchers interpreted their results in terms of their “cognitive theory of multimedia learning”, which draws heavily from cognitive load theory. They proposed that lengthy verbal explanations may in fact distract the learner with unnecessary information, which adversely affects their cognitive processing and thus their learning.
In contrast, a concise infographic provides only the important information. This reduces the cognitive load, making it easier to process and to “learn”.
Text ain’t half bad
I’ve professed my support of text in a previous blog article, so before we all abandon tedious words in favour of flashy infographics, I caution that text will always have its place – especially to explain the details.
For example, the multimedia summary studied by Mayer may have been sufficient for first-year science students, but probably not for meteorology majors. Those guys need the detail, and text is usually the most efficient way of providing it.
However, I still feel that pictures can be a useful pedagogical device for students who aspire to be experts. In particular, by using an infographic as an advance organizer or pre-reading, the instructional designer can promote a mental model of the domain.
This approach enables the student to devote their cognitive efforts to processing the initial conceptual framework, prior to following it up with more substance once a broad understanding of the main concepts is achieved.
My two cents’ worth
So, in summary, here is my reflection on the power of pictures:
• Pictures look pretty. Use them to increase engagement.
• A picture paints a thousand words. Use one to replace wads of text.
• An infographic is a concise means of delivering the key concepts to novice students.
• An infographic can provide experts-to-be with an initial conceptual framework, which can subsequently be “filled in” with further detail.
Putting it into practice
I decided to put my ideas into practice and create an infographic for my workplace.
So, using nothing more than Microsoft PowerPoint and some clipart, I created a customer-centric explanation of what we do:
I feel this picture would be a useful addition to our inductions, to explain to new recruits up-front the overall purpose of our company.
The graphic may also act as an introductory piece for our product training, placing it into context for the learner.
The graphic might even act as an attractive desk poster to reinforce the key messages on a day-to-day basis.
I’m sold, give me more!
