2. CONTEXT: LLL FOR PEOPLE WITH FUNCTIONAL DIVERSITY
People with disabilities choose distance education universities (eLearning) for their
studies. (50% UNED)

3. CONTEXT: ACCESSIBLE MOOC LEARNING
.
Benefits such as:
• Openness
• Low cost
• Ubiquity
• Acquiring knowledge
• Social learning
• Achieving new competences
• Develop professionally

The fact to make digital people with special needs increases the
work rate in this collective
4. DOCTORAL WORK OBJECTIVE
• Adaptive model.
• The system will help to find MOOCs that best suit their
professional needs and that are more accessible regarding
hisher disability.
• Accessibility Analysis of both of eLearning platforms and
educational resources.
• Personalization of the app: GUI adaptation to each assistive
technology.
• Rated list of recommended MOOCs to best fit accessibility
requirements and learning preferences.
The main objective of this doctoral work: Design a PERSONALIZED APP for
RECOMMENDING MOOCs adapted to user needs: achieve new professional
competences + learner’s preferences.
5. COMPETENCE-BASED RECOMMENDATION APP FOR PEOPLE
WITH FUNCTIONAL DIVERSITY
Enriched user profile. There are two main groups of information:
1. list of professional competences the user wants to achieve -> what the person wants
to learn
2. User’s device personalization: preferences / needed assistive technologies ->
technical needs regarding user’s functional diversity.
6. COMPETENCE-BASED RECOMMENDATION APP FOR PEOPLE
WITH FUNCTIONAL DIVERSITY
Professional profiles defined by competences.
The system should have professional skills defined to be mapped to user expectations.
MOOC content defined by achievable competences.
The information of competencies within the MOOC platforms and courses.
Accessible MOOCs.
Accessibility evaluation on MOOC platforms and their educational resources
-> automated recommendation list adapted to user’s functional diversity (user’s profile).
9. COMPETENCE-BASED RECOMMENDATION APP FOR PEOPLE
WITH FUNCTIONAL DIVERSITY
TASK 1: Development of an accessibility evaluation of MOOC platforms and courses to
achieve a map of accessible MOOCs versus functional diversities.
TASK 2: Development of a holistic approach assessing accessibility in MOOCs using
different tools (automatic tools, disability simulators,…)
TASK 3: Analysis of accessible metadata for user profile definition:
{assistive technologies, device user preferences instead of functional disability
TASK 4: Enriched user profile definition:
• functional diversity (from Task 3)
TASK 5: Accessibility map: MOOC vs user’s functional diversity
10. TASK 1: HOW SHOULD THE MODEL FOR AN ACCESSIBLE MOOC
PLATFORM BE?
The minimum required level of
accessibility :
Guarantee access to the
content by means of the
platforms.
Produce the content
accessible in itself.
Evaluate the access conditions.
The technological platform.
The content of the MOOC must be
the same for all of the students.
The students must be able to access
the content using assistive
technologies.
It is necessary to offer alternative
textual descriptions for multimedia
content.
Assistance must be provided.
11. TASK 1: CREATING ACCESSIBLE MOOCS. THE IMPORTANCE
OF STANDARDS
eLearning platform
standards:
Web Content
Accessibility Guidelines
(WCAG) 2.0 (2008)
Website Accessibility
Conformance Evaluation
Methodology
1.0 (2014)

12. TASK 1: CREATING ACCESSIBLE MOOCS. THE IMPORTANCE
OF STANDARDS
•Documents:
o PDF, Word. Follow Accessibility
guidelines for documents
•Videos (pills)
o Include subtitles.
o Sign Language Interpreter
o Include alternative text to the video
content. Textual description
13. TASK 1: METHODOLOGY AND GUIDELINES FOR EVALUATING
ACCESSIBILITY IN MOOCS
A selection of a set of Web pages:
•The platform’s homepage.
•A representative page of the course.
•A course page including a form.
•A course page including a forum.
Educational resources (Knowledge Pills)
Text based: PDF, Word,…
Multimedia, Video lessons.
Methodology that combines:
Conformance reviews.
Screening techniques.

"Estrategias de
Marketing Online.
Community Manager"
(Miriada X. ).
"Emprendimiento y
Desarrollo de
Aplicaciones de
Realidad
Aumentada"
(COLMENIA:
Weprendo + UnX).
“As alterações

15. TASK 1: CASE STUDY RESULTS
All platforms obtain average results 5 – 6 /10 -> place for improvement. None of the
platforms achieve reasonable values (higher than 60%).
For the educational content -> no standards (either platforms or accessible
educational content). -> SCORM and accessibility guidelines.
Lack of full accessibility of audiovisual resources exist for all the platforms.
16. TASK 2: HOLISTIC APPROACH FOR EVALUATING
ACCESSIBILITY IN MOOCS
Global or heuristic vision:
Evaluation through automatic
accessibility tools :
WCAG Accessibility Validation:
eXaminator
Disability Simulators:
aDesigner
User Experience (UX)
Testing Tools: Sortsite
User evaluation
Educational content evaluation
The MOOC
platform
The educational
content.

17. TASK 3: ANALYSIS OF ACCESSIBLE METADATA FOR USER PROFILE
DEFINITION
Analysis of accessible metadata for user profile definition: {assistive technologies, device user
preferences instead of functional disability}
Rodrigo C., Iniesto F. (2015) Holistic vision for creating accessible services based on MOOCs. Open Education Global Conference. 2015.
18. Learning Profiling:
•Display information: the user preferences to have information displayed or
presented. For example, it is possible to define preferences related to text (fonts and
colors), video (resolution), mouse (pointer, motion), etc.
•Control information: this set defines the user preferences to control the device:
keyboard (virtual), zoom preferences, voice recognition.
•Content information: this set defines the user preferences for visualizing learning
content.
•Privacy and data protection information: The privacy and the data integrity is
considered very important, since the exchanged information can be closely related to
the user’s functional diversity.
TASK 3: ANALYSIS OF ACCESSIBLE METADATA FOR USER PROFILE
DEFINITION
19. Learning Resources:
•Technological: the technology to develop and edit the resources, authoring tools to
facilitate the production of accessible materials or the adaptation of those already
produced.
•Adapted Devices: when a user accesses a resource available on the Internet, it can
be accessed directly or a device would have to be used specifically: screen reader,
specialized mouse, virtual keyboard, magnifying glass, etc.
•Existing Inclusive Methodologies and Educational Standards: in this sense the XML
markup languages have to be mentioned.
