We have discussed in previous blogs, the importance of graphics in eLearning design and development, and how much impact they make on the learners mind and the learning outcomes. Let’s see some of the guidelines for the legibility of graphics in eLearning design.
- Color choices: Certain colors evoke emotions and convey moods. Active colors like yellow, orange, red, and purple etc., can be used for highlighting certain important parts of the course. Red is not usually preferred, when the target is an international audience.Passive colors like greens, blues and lighter purples are usually preferred as supporting background colors.
Color and contrast go in similar lines. When talking about contrast, black and white form an ideal contrast. Black lettering on white screen background can be easily read, as they contrast to each other very well. On the other side, blue on black or yellow or white are poor contrasting colors and cannot be read easily. Similarly, strongly contrasting colors like green on orange is painful to read. The same goes with the graphics too.
- Charts and graphs: An interesting way of using charts, is by using images that are related to the content represented through charts. For example, rain drops can be used instead of rectangles, while representing the rainfall in a particular region, in different seasons. Every chart must be ensued with accuracy and clarity in the presentation.
Charts and graphs are a smart way of presenting information, as the contents can be grasped just by a glance. Charts and graphs can be easily created in PowerPoint or MS Excel and they certainly have an edge over the lengthy text, owing to the little extra work.
- Copyright guidelines for online imagery: Photo shooting our own images to use them in eLearning courses may be a costly affair, owing to the studio expenses. However, there are some good photography agencies. Royalty-free photographs can be purchased from them at decent prices. Certain agencies like iStock, Stock Xchange etc have a very wide range of images. These images can be ordered and purchased online. All that we need to ensure here is, that we follow proper copyright guidelines, while acquiring these images online!
- Graphic size: The size of the graphic must be optimized, such that they hardly take any time for loading. Though adding graphics may lead to better learning outcomes, using too many graphics of various colors and quality, in a single slide, may disrupt the clarity and further add to the complexities. Be selective while selecting the number of graphics to be used per slide. Ensure that there is no time lag between graphic loading and the loading of other screen elements. Do not overcrowd the screens with heavy graphics.
These are some of the guidelines. Keeping them in mind while designing graphics for an eLearning course, will go a long way in giving the learners a pleasant experience while taking the course.
