*perceived usefulness: Defined as how a student’s performance, or learning performance, can be enhanced by a system. Studies show the impact of perceived ease of use and perceived usefulness and their role in a users’ decision on whether to use a system again. Scaffolding as well as accommodations to the student’s learning style will help overcome limitations of system operations, as will feedback geared toward system improvements.<ref>Alsobhi, A., Khan, N., & Rahanu, H.

*system adaptability: Refers to the user experiences and the way in which students are given control over a system to increase confidence and comfort in their learning. In addition to implications for the system, the flow of content shouldb be logical and the tone (attitude) of content should be encouraging.<ref>Alsobhi, A., Khan, N., & Rahanu, H. (2015).

=== 508 Compliance & the implications for Educators ===
Educators that choose to use the CSCL environment must be aware of 508 compliance and its legal implications. “In the U.S., the criteria for designing Web pages accessibly are provided by two major sets: the W3C’s Web Accessibility Guidelines (WCAG) and the design standards issued under U.S. federal law, Section 508 of the Rehabilitation Act, as amended in 1998.1 Features of accessible design include, among others, the provision of ALT tags for nontextual elements, such as images, animations and image map hot spots; meaningful link text; logical and persistent page organization, and the inclusion of skip navigation links."<ref>Axel Schmetzke & David Comeaux (2009) Accessibility Trends among Academic Library and Library School Web Sites in the USA and Canada, Journal of Access Services, 6:1-2, 137-152, DOI: 10.1080/15367960802286286</ref>
Unfortunately, not all educators are exposed to these guidelines, especially if their collegiate programs do not provide exposure to the use of computers, aspects of web design or technology in education. In some cases, it may be advantageous for the educator to collaborate with an instructional technologist or web designer to ensure 508 guidelines are addressed in the desired learning environment for the CSCL.
