“…For an PLE to be adapted, according to Maguire, Elton, Osman and Nicolle [8] it is necessary to ensure accessibility, usability, individualization, multimedia interfaces, assistive technologies and curriculum compliance. Although accessibility, as noted by these authors [8], is important in a system accessed by individuals with different characteristics, it can be difficult to achieve. According to Dix, Finlay, Abowd, and Beale [8], for a system to present usability it must be simple and intuitive, consistent with conventions and norms, flexible and efficient, clear to act and react and help the user to avoid errors and make it possible to recover from errors.…”
