The Inclusive Learning Exchange: Supporting Learner-Centric Transformation of Content Laurie Harrison Adaptive Technology Resource Centre University of Toronto
Need for personalization of learning object : Accessibility for people with disabilities Background knowledge Learning preferences Pace and path
Learners with Disabilities Lack of access to: Textbooks or printed material Speech or Audio Visual material Note-taking Class discussions
However, learners using adaptive technology… Access digitized educational resources via: Screen readers Screen magnification Alternative pointers, keyboards Voice Recognition Text-to-Speech
Not to mention learners using: Text-only screen Older or different browser Second language Slow Internet connection Wireless, PDA, other mobile devices …or those accessing learning resources from non-traditional settings or environments
TILE Project Learning environment that supports personalization for individual learning needs
customization during the instructional design phases use of IMS Learner Information Profile (LIP) to accommodate individual learner preferences “…exploring the practical boundaries of transformable content and the tools needed to support the mastery of learner customizable teaching.”
Strategy 1 Independence of content and structure from presentation to accommodate learner preferences: Flexible display Flexible content aggregation
Example – Flexible Display
Example – Flexible Content Aggregation
Strategy 2 Independence of function from control method to accommodate needs and preferences Flexible control using range of input methods Flexible navigation
Example – Flexible Input
Example – Flexible Navigation
Strategy 3 Increased granularity of learning objects to allow presentation of alternative formats and modalities Captioning ASL Described Video
Example – Range of Modalities
Strategy 4 - Session-specific Preferences Learner Outcome Goals Topic Exclusion Placeholders
Example - Learner Outcome Goals
Strategy 5 Implementation of accessibility guidelines and interoperability specifications Access system friendly interfaces Every learner with a disability is potentially a different external “system” that needs to inter-operate
Guidelines and Specifications Web Accessibility Guidelines Accessible Authoring Tools IMS Global Learning Consortium Accessibility Guidelines
IMS Specifications - TILE Accessibility Extensions to the Learner Information Profile (ACCLIP) - encodes learner preferences. Metadata – developing extensions to allow identification of resources that meet the criteria indicated in the learners preferences (i.e. ACCLIP) Content Packaging –packaging the content up into ‘modules'; identification of alternate resources
IMS Specifications - ACCLIP
ACCLIP
Interoperability and IMS Implementation of the IMS specifications allows interoperability with all other IMS compliant repositories and systems
Summary Greater granularity, modularity and transformability Independence of content and structure from presentation Metadata on equivalents Method of expressing preferences (ACCLIP) Support for specified transformation Dynamic retrieval of specified equivalents and style sheets
Conclusions Enhancing learning for all learners Improving the longevity and efficacy of our learning materials “For learners with disabilities, accessibility makes things possible - not just convenient.” Jutta Treviranus
