Visual learning has always been an important part of our learning process but the emergence of the internet and the subsequent growth of online learning has brought it to the center of our learning experience.
Most of the successful online courses today use videos, infographics, presentations, etc. as the primary learning format, and there is a good reason behind it.
There is enough research that supports the argument that it is faster, easier, and more effective to learn visually.
And in this article, we are going to discuss several research-backed arguments to illustrate the power of visuals in online learning.
Let's start with this infographic that summarizes the key advantages of visual aids in online learning:

1. Visuals Make Communication Quicker
We can notice and make sense of visual information much faster than we can read any piece of text.
For example, when it comes to recognizing patterns in data — most of us find it easier to look at charts or graphs than spreadsheets.
While you may be able to relate to the idea intuitively, they are also backed by research. According to the Visual Teaching Alliance:
The whole thing becomes even more important when you consider the fact that the attention spans of humans are getting shorter.
In fact, one study suggests that the average person gets distracted in 8 seconds, though a mere 2.8 seconds is enough to distract some people.
As a result, it’s important for you as an educator to communicate your message to the learners quickly, and so, you need to use more visual content like videos and images while creating an online course.
2. They Aid Long-Term Retention
A key aspect of effective learning is to be able to remember information over the long term.
Through visual learning, our brains tend to associate concepts with meaningful images, which helps us store those concepts in our long-term memory.
According to Dr. Lynell Burmark, an education consultant, “Words are processed by our short term memory where we can only retain about seven bits of information. Whereas, images are directly processed by our long-term memory, where they get indelibly etched.”
Now, there is enough research that also suggests that learning through visuals increases the likelihood of us storing information in our long-term memory.
One study showed that after three days of learning new information, users remembered only 10-20% of what they learned through text or voice but ended up retaining 65% of what they learned visually.
According to another study, an illustrated text was 9% more effective than text alone when immediate comprehension was tested and 83% more effective when the test was delayed.
Moreover, visual elements also reinforce important takeaways, which makes it more likely for us to remember key pieces of information over the long term.
3. They Improve Our Grasp of Concepts
Visual cues ignite our imagination, help us create new associations, and rearrange existing patterns in memory. Visual elements also help us in simplifying complex ideas by making it easy to break down concepts and reorganize information.
So it’s hardly a surprise that visuals improve our overall ability to understand concepts in greater depth and granularity and increase ‘‘human bandwidth’ for learning.
According to Robert E.Horn from Standford University, “When words and visual elements are closely entwined, we create something new and we augment our communal intelligence ... visual language has the potential for increasing ‘human bandwidth'—the capacity to take in, comprehend, and more efficiently synthesize large amounts of new information."
There has been a lot of research which supports these ideas and suggests that Visuals improve comprehension and other learning outcomes.
According to a study, Visuals have been found to improve learning by up to 400 percent.
Other studies have found that visuals such as graphic organizers improve performance in areas including:
4. Visuals Evoke Emotional Response
Visual memory is stored in the same part of our brain, where emotions are processed. Visual stimuli, our emotional responses to them, and the act of forming memories are closely linked with each other.
So, visuals can trigger strong emotions in us, and we often tend to remember the pairing of emotions and visuals in vivid detail.
And it’s not just about evoking strong responses, even a subtle level of emotional engagement with the learning material can increase our attentiveness, and spike up our interest level in the subject.
As a result, visuals that engage us emotionally can dramatically improve learning outcomes. On the other hand, dry content which triggers no emotional response is likely to be ignored by our brains.
5. They Drive Motivation for Learning
Visuals are much more effective at holding the attention of learners, retaining their interest, and motivating them to learn new information.
As 65% of people are visual learners, they pay close attention to information-carrying images. In fact, when the images are relevant, readers spend more time looking at the images than they do reading text on the page.
Another study suggests that around 40 percent of learners respond better to visual information than text alone.
Online course creators can benefit from this awareness to incorporate visual elements and storytelling to motivate students.
Incorporating Visuals in Online Learning
There are a few things to remember while incorporating visuals in online learning because their wrong use can easily distract learners.
Firstly, visuals should not be used for purely aesthetic reasons; rather they should be used for representing specific ideas and objects, for simplifying complex concepts, and for connecting new ideas with old concepts.
Secondly, things like low-resolution images, overuse of stock photography and generic visuals should be avoided, as they can cause learners to lose interest.
Thirdly, there are several visual content formats like videos, images, infographics, illustrations, etc. which you can use in your training programs and so, it's important that your online learning platform supports these formats.
Finally, how visuals are paired with other forms of content is equally important as the quality of visual elements itself.
In a nutshell, visuals can play a powerful role in online learning for improving learning outcomes, especially if they are used thoughtfully and strategically.
