According to Mayer’s model of meaningful learning, the learner processes a visual information processing system and a verbal information processing. Hence narration goes into the verbal system where animation goes into the visual system.
Is applied to incoming verbal information to yield a text base and is applied to incoming visual information to yield an image base.
Is applied to the image base to create a verbally-based model of the to-be explained system and is applied to the image base to create a visually-based model of the to-be explained system.
Occurs when the learner builds connections between corresponding events (or states or parts) in the verbally-based model and the visually-based model.
Establish that its is better to present an explanation in words and pictures that solely in words.
When giving a multimedia explanation, present corresponding words and picture contiguously rather than separately.
When giving a multimedia explanation, present words as auditory narration rather than as visual on screen text.
The foregoing principles are more important for low-knowledge than high-knowledge learners, and for high-spatial rather than low spatial learners.
When giving a multimedia explanation, use few rather than any extraneous words and picture.
“There is evidence to indicate that the manner in wich information is presented will affect how well it is learned and remember”. (Richard E. Mayer, 2005; 147) Presenting some information in visual mode and information in auditory mode can expand effective working memory capacity and so reduce the effects of an excessive cognotive load.
Students learn better when the associated statements are narrated rather than presented visually. Split- attention effects-the two sources of information are still presented visually but in physically integrate form. Modality effect-written statements are converted to spoken statements.
According to cognitive load theory, many instructional materials and techniques may be ineffective because they ignore the limitations of human working memory and impose a heavy cognitive load.
Instructional procedures can alleviate extraneous cognitive load by formatting instructional material in such a way that minimizes cognitive activities that are unnecessary to learning so that cognitive resources can be freed to concentrate on essential activities. The consequences of extraneous cognitive load can also be alleviated by increasing effective working memory capacity.
Occurs when two or more sources of visual information must be processed simultaneously in order to derive meaning from material.
To obtain the split-attention effect, the two visual separated sources of information are physically integrated to reduce the need for mental integration.
To obtain the modality effect, verbal material is presented when such dual-mode presentation is superior to a visual-only, split-attention presentation.
The modality effect can be explained by acribing memory load to each of the treatment condition, the diagram (or picture) with text presentation induces a higher both sources of information are processed in the systems.
Effective working memory capacity may be increased and this increase can be used to reduce cognitive load and facilitate learning. Under split-attention conditions, learning may be facilitated by presenting a written source of information in auditory mode.
