Dana Jandhyala, who has had a long career as an educator where she has taught in different schools and institutes, believes that visuals hold more appeal than plain text to curious and intuitive minds.
"Till date, several studies have been conducted which prove the power of visual aids in eLearning," she wrote. "And there are some interesting results drawn from them. Such as, learners respond to visual information faster as compared to text-only materials. Also, visuals help improve learning tremendously and on multiple levels. Hence, around 65% of the population comprises visual learners."

Jandhyala said there are several advantages of visual aids:
They help store information longer. "Images are the simplest and the most effective way to make sure that the information gets stored as long-term memory. As per Dr. Lynell Burmark, an education consultant, our short term memory processes words and can only retain about seven bits of information. Whereas, images are directly processed by our long-term memory, where they get indelibly etched."
They make communication quicker and simpler. "Information listed in bullets is no doubt simpler to process. But, that same information in the form of an image or a video is processed even more quickly."
As per the Visual Teaching Alliance:
- Of all the information transmitted to the brain, 90% is visual;
- As opposed to text, visuals are processed 60,000x faster;
- Humans are capable of getting the sense of a visual scene in less than 1/10th of a second;
- 40% of nerve fibers are linked to the retina;
- Our brain can see images that last for only 13 milliseconds;
- The human eye can register 36,000 visual messages every hour;
- Hence, the eLearning programs which incorporate suitable visuals gain a higher preference over.
Visuals aid better comprehension. "They help learners grasp concepts easily by stimulating imagination and affecting their cognitive capabilities. Besides, the visual language is also known to have the potential to stretch 'human bandwidth' – which comprises absorbing, comprehending and analyzing new information."
Visuals act as stimulators for emotions. "Emotions and visual information are processed in the same part of the human brain. Visual stimuli and emotional response are linked in a simple way and these two together generate what we call memories. Hence, powerful images and visual metaphors create strong impressions and lasting memories in learners."
They drive motivation. "Most of the students struggle with some of their subjects because they find them uninteresting and hence lack the motivation to put in the required efforts. Visuals are the best bet in such scenarios. Captivating images, engaging videos, interesting infographics, etc. help learners fight the boredom and motivate them to do better."
So it very well might be that the things you'll learn from these guides will stay with you. At least for a little while.
