2  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.

3  Selecting  Organizing  Integrating

4  Is applied to incoming verbal information to yield a text base and is applied to incoming visual information to yield an image base.

5  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.

6  Occurs when the learner builds connections between corresponding events (or states or parts) in the verbally-based model and the visually-based model.

7  Establish that its is better to present an explanation in words and pictures that solely in words.

8  When giving a multimedia explanation, present corresponding words and picture contiguously rather than separately.

9  When giving a multimedia explanation, present words as auditory narration rather than as visual on screen text.

10  The foregoing principles are more important for low-knowledge than high-knowledge learners, and for high-spatial rather than low spatial learners.

11  When giving a multimedia explanation, use few rather than any extraneous words and picture.

12  “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.

13  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.

14  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.

15  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.

16  Occurs when two or more sources of visual information must be processed simultaneously in order to derive meaning from material.

17  To obtain the split-attention effect, the two visual separated sources of information are physically integrated to reduce the need for mental integration.

18  To obtain the modality effect, verbal material is presented when such dual-mode presentation is superior to a visual-only, split-attention presentation.

19  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.

20  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.
