After 18 years in the field of e-Learning and as a doctoral learner in instructional design and online learning, I am intrigued by the intersection of usability and accessibility in the many delivery options offered by the online learning environment. Many terms define and describe the online delivery environments, and as these options expand the audiences and learners also grow more diverse. The downside to the exponential growth of e-Learning is that the more e-Learning expands around the world, the more disparate the usability and accessibility becomes, leading to more incongruent learner experiences.
I mean, how many of us have been to websites that just don’t work well? How many times have we just given up when trying to locate information because it wasn’t clear where to navigate or just took too long to find? Even worse, how many of us have taken online training that frustrated us with poor or inconsistent navigation, or led us to a dead end where we couldn’t complete the course? Frustrating, right?
Usability and accessibility do somewhat overlap, but have very different impacts on the learner. For those of us without a disability, not being able to get to course content easily or finding the course not useable may generally create a nuisance, a frustration or an inconvenience – this is a usability issue. For individuals with disabilities such issues are not just frustrating, they may create barriers to learning – an accessibility issue.
Yates (2005) emphasizes that usability and accessibility are not one and the same; a website might be useable, but not accessible (p.182), or vice versa. Combining usability, or the ease of use for a web site (p. 183), and accessibility, the extent a web site removes barriers to individuals with disabilities (p. 184), equals an enhanced user experience for all. Examples of similar or like aspects of accessibility and usability include consistent navigation, the ability to change screen font size and links that are labeled to indicate where they lead. Attention to the nuances between accessibility and usability have a positive impact on the design of a good online learning experience, allowing ease of use for everyone, and access for individuals with disabilities.
Addressing usability and accessibility for online learning does not just stop at the technical side of development. Rose and Meyer (2002) accentuate the importance of not only providing physical access to learning, but providing access to learning itself for all learners, and special needs learners through application of Universal Design for Learning principles to instructional design processes. They believe “barriers to learning are not. . .inherent in the capacities of the learner, but arise in learners’ interactions with inflexible educational materials” (p. iv). Instead of catering or adjusting the curricula for specific and/or disabled individuals, inclusion of universal design will cater to almost all learners.
