The notion behind open education resources or OERs is just for educators to share studying supplies on as a lot of subjects as attainable so learners can access them easily and for no cost. Examples of adaptive technologies include mobility devices (walkers, wheelchairs, and so forth.), FM and/or sound field systems (for students with hearing impairments), braillers or print enlargers (for students with visual impairments) and personal care items. In addition to AT, some students with learning disabilities may well also have physical or healthcare conditions that necessitate specialized adaptive equipment to access the curriculum and/or option system. This may be mainly because the student is obtaining them openly on the internet, or mainly because tutors, teachers and lecturers are themselves recommending sources.
