Context: lll for people with special needs Integrates education, work and personal life in a continuous process. People with special needs choose distance education universities (eLearning)

for their studies. 7.500 enrolled students at UNED represents 50% of total Spanish univeristy

students with a disability

RATIONALE. STUDY CONTEXT

Context: ICT + Disabilities:

• The possibilities that ICT offer people with disabilities to improve their wellbeing and the possibility of their insertion into the work market.

• The fact to make digital people with special needs increases the work rate in this collective.

• 100% consider that the incorporation of ICT into the workplace has increased their work possibilities.

(Díaz & Bonjoch, 2007; Vila et al, 2007; Kop & Bouchard, 2011; Lewis, 2014)

Context: Accessible MOOC Learning:

Benefits such as:

• Openness

• Low cost

• Ubiquity (Time, space and rhythm)

• Acquiring knowledge

• Social learning: Connectivism

• Achieving new competences

• Develop professionally

(Downes, 2013; Siemens, 2013, Morrison, 2013; Zapata-Ros, 2013, Haggard, 2013, Teixeira & Mota, 2013; Waard et al 2014; Gaebler, 2014)

OBJECTIVES

• The system will help to find MOOCs that best suit their professional needs and that are more accessible regarding his\her disability.

• Accessibility Analysis of both of eLearning platforms and educational resources.

• Personalization: adaptation to each assistive technology.

• Rated list of recommended MOOCs to best fit accessibility requirements and learning preferences.

DESIGN a personalized app for recommending MOOCs adapted to user needs: achieve new professional competences + learner’s preferences.

MOOC data definedby achievable competences

OBJECTIVES

Competence-based recommendation app for people with functional diversity

1. Enriched user profile.

• User’s device personalization: preferences / needed assistive technologies -> technical needs regarding user’s functional diversity.

2. Accessible MOOCs.

• Accessibility evaluation on MOOC platforms and their educational resources-> automated recommendation list adapted to user’s functional diversity (user’s profile).

Objective suported by (Rodriguez-Ascaso & Boticario, 2015): Functional Diversity Scenario.

Page 8: Accessibility issues in MOOCs: potential services  for people with special needs

METHODOLOGY

TASK 0 (transversal): Literature review/update

TASK 1: 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/Selection 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 accessibility vector of characteristics vs user’s functional diversity

TASK 6: Literature enhancement and thesis paper development.

Page 9: Accessibility issues in MOOCs: potential services  for people with special needs

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.

Task 0: (Sanchez-Gordon & Luján-Mora, 2013; Najd et al, 2014; Bohnsack & Puh 2014; Sanchez-Gordon & Luján-Mora 2015; Rodríguez-Ascaso & Boticario, 2015)

Page 10: Accessibility issues in MOOCs: potential services  for people with special needs

(Sanchez-Gordon & Luján-Mora, 2013). Review of five Coursera courses. Authors found Web accessibility problems in Coursera platform and the contents of the five courses, limiting access to elderly students.

(Najd et al, 2014). Evaluation of 10 Coursera courses on different topics (technology, design, humanities, physics, etc. according to WCAG 2.0 is aimed to blind or partially sighted people, none of the courses reaches the level A. These affect important tasks as browse the contents, access to the video classes, or perform test and exercises.

(Bohnsack & Puh, 2014). Evaluation of the accessibility of the five MOOC platforms more popular in the United States (Udacity, Coursera, edX) and in Germany (OpenCourseWorld and Iversity) for blind users. The experiment was stopped at the point at which an accessibility problem prevented the user from continuing without help. All platforms (except edX) had fatal accessibility problemsin the initial stages of the interaction.

(Sanchez-Gordon & Luján-Mora, 2015). Proposal of a three-layer architecture to extend the platform Open edX to enhance course content accessibility for users with disabilities. The goal of the proposed extension is to enhance MOOCs’ accessibility by adapting course content to student needs, preferences, skills and situations.

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 accessibility of audiovisual resources exist for all the platforms.

Page 20: Accessibility issues in MOOCs: potential services  for people with special needs

TASK 2: HOLISTIC APPROACH FOR EVALUATING ACCESSIBILITY IN MOOCS

Global or heuristic vision:

MOOC accessibility vector of characteristics.

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.

TASK 3: ANALYSIS OF ACCESSIBLE METADATA FOR USER PROFILE DEFINITION

Task 0: (Takagi et al, 2008; Boticario & Santos, 2008, Otón et al 2014)

IMS Access for All (AfA) : Personal Needs and Preferences (PNP) and Digital Resource Description (DRD) -> Multiplicity (Collections)

( Rodrigo & Iniesto, 2015)

Page 22: Accessibility issues in MOOCs: potential services  for people with special needs

Learning Profiling:

•Display information: the user preferences to have information presented. define preferences related to text (fonts and colors), video (resolution), mouse (pointer, motion)

•Control information: user preferences to control the device keyboard (virtual), zoom preferences, voice recognition)

•Content information: user preferences for visualizing learning content.

•Privacy and data protection information.

TASK 3: ANALYSIS OF ACCESSIBLE METADATA FOR USER PROFILE DEFINITION

Learning Resources:

•Technological: the technology to develop and edit the resources. (authoring tools to facilitate the production of accessible materials)

•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).

•Existing Inclusive Methodologies and Educational Standards: XML markup languages.
