Didactic Material-Learning multimedia

Multimedia learning

The core of multimedia

learning from the viewpoint of psychology is

combined

comprehension of text and pictures

Spoken text, written text, maps, drawings, graphs and sound

Descriptive representations

Depictive representations

Multimedia learning occurs when and individual understands what is represented

It consist in symbols, are more powerful in expressing abstract knownledge.

Example: Mathematical expression such as V= s3

It consist in icons, are therefore more useful to draw inferences.

Example:Photographs, drawings and paintings.

Mental representations

Multiple memory systems

When learners understand texts and pictures, they construct multiple mental representations in cognitive system

Working memory

Sensory register

Long-term memory

Working memory consist of a central executive and different subsystems for the storage of information

Auditory working memory

Visual working memory

There are multiple sensory channel according to the multiple sensory modalities between the outside world and working memory

Text and picture comprehension require prior knownledge that is stored in long-term memory. Cognitive schemata

Text and picture comprehension take place in cognitive architecture incluiding a working memory of limited capacity,modality-specific sensory registers as information input systems, and long term-memory

Verbal information and pictorial information is transmitted to working memory trought the visual channel and the auditory channel. The channels have limited capacity to process and store information

Further information processing in working memory takes place in two different representational channels: the verbal channel and the pictorial channel. Information from written or spoken text is processing the verbal channel.

Integrated comprehension of text and pictures

(Multiple memory system,working memory, multiple mental representation, congnitive theory of multimedia learning)

Listening comprehension

Visual picture comprehension

Auditory picture comprehension

Auditory verbal information enters the auditory register trought the ear and is then forwarded trought the auditory channel to auditory working memory. The information is passed trought the verbal channel to propositional working memory, leads to propositional representation

Visual pictorial information enters the visual register trought the eye and is then forwaded through the visual channel to visual working memory, where it results in a visual perceptual representation of the picture

If a sound is understood ,auditory pictorial information enters the auditory register through the ear and then forwaded through the auditory channel to auditory working memory
