Audio-based access to e-learning

What for?

Learning processes in which sound is the main source of information

Students with perceptual auditory learning styles

Hands-busy, eyes-busy and mobility-required situations

The device has speech input/output capabilities but lack of usable displays or keyboards

A disability does not allow a person to make use of a visual display

Results

Aural contents have didactic value for e-learning courses

There is a relationship between learning styles and type of content

Aural

Visual

ConclusionsIntegrate audio features with e-learning

Develop an evaluation method: usability and didactic effectiveness

Test the method: • Didactic value of aural contents• Relationship between learning styles and

content types

Evolve & complete this method Add parameters: memorability and learnability
