Notes
There are several levels at which to evaluate accessibility. You can evaluate learning resources, websites, accessibility policies, and service provision.
Learning resources
Different studies have approached the evaluation of learning resources differently. This chapter discusses a dozen or more studies that focused on evaluating the accessibility of resources as varied as Google Docs, e-book platforms, and LMSs. The studies approached their evaluations in different manners, such as:
- Evaluating the technical and functional aspects
- Testing users on how they perceived the “ease of use” of a resource as a way to identify ‘perceptual, usability, and technological barriers’ (Seale, 2014, p. 94)
- Conducting surveys of small groups of users to understand the depth of their knowledge of the accessibility features of a resource
Websites
- Most studies that evaluate web accessibility in the higher education arena focus on three areas of a schools’ website: the home page, the main library page, and a sample course page.
- Sometimes tools are used to provide an even-handed accessibility report; one such tool is WAVE. Other studies use a combination of these tools and human testing, to add subjective, qualitative assessment.
Policies
One interesting study that evaluated accessibility policies was a large-scale study conducted in 2010 of 50 American universities (one in each state). They needed to evaluate the policies against a standard, and so they started with WebAim’s seven criteria for accessibility policies and then added to that six more it. Here’s what they found:
This criteria... | From... | Was met by... |
---|---|---|
Reasons for the accessibility policy | Bradbard | Most of the schools |
Standards and guidelines | WebAim | Most of the schools |
To whom the policy applies | WebAim | Less than 50% of the schools |
Definitions | Bradbard | Less than 50% of the schools |
Lists of responsibilities | Bradbard | More than 50% of the schools, but not in detail |
Training resources | WebAim | Less than 50% of the schools |
Tips and examples | Bradbard | Most of the schools |
Validation tools | Bradbard | More than 50% of the schools, but not in detail |
Timeframe for implementation | WebAim | Less than 50% of the schools |
How accessibility efforts are approved | WebAim | Less than 50% of the schools |
How the policy will be enforced | WebAim | Less than 50% of the schools |
What happens when the standards are not met | WebAim | Less than 50% of the schools |
Contact information | Bradbard | More than 50% of the schools, but not in detail |
(This is my summary of Bradbard et al. (2010), as told by Seale (2014), pp. 109-110)
Service provision
There are several different levels for evaluation:
- Institutional: Our laws are focused on changing practice at this level.
- Service: This is the department, unit, school, or faculty level, and there is a gap here.
- I thought this was an interesting comment: ‘In thinking about how useful it is to audit or evaluate accessible e-learning service delivery, it is possible to see that services would be resistant to having to undergo yet another quality assurance exercise on top of all the others that they are required to undertake by their institutions and by external funding agencies. Therefore any audit tool that is developed will probably need to be developed by and for service providers, probably with a view to using it as an informal self-development tool’ (Seale, 2014, p. 118).
- Individual: Many guidelines and standards are focused on this level.
