PURPOSES OF VISUALS
4. DIRECT ATTENTION
VISUALS ARE ICONIC
- that is, they have some resemblance to what they represent.
using photographs of people voting to represent freedom, a series of connected beads to show a model of DNA, or a diagram of a word endings to assist beginning readers are example of showing something "real" to illustrate abstract ideas.
visuals can motivate learners by attracting and holding their attention while generating engagement in the learning process.
draws the learner's attention and thinking to relevant parts of a visual. It may be color, words, icons, shading or animation. Use these signals to focus attention to important points within complex visual content.
5. REPEAT INFORMATION
When visuals accompany spoken or written information, they present that information in a different modality, giving some learners a chance to comprehend visually what they might miss in verbal or text format.
6. RECALL PRIOR LEARNING
At the beginning of a lesson visual's can activate prior knowledge stored in long term memory and at the end they can summarize the content from a lesson. These same visuals can be used at the beginning of the next lesson to remind the learners of what should have been learned.
7. REDUCE LEARNING EFFORT
Visuals can simplify information that is difficult to understand.Diagrams can make it easy to store and retrieve such information. They can also serve an organizing function by illustrating the relationships among elements, as in flowcharts or manuals.
CATEGORIES OF VISUALS
It shows the actual object under study. They can translate abstract ideas into a more realistic format allowing instruction to move from the level of abstract symbols on the concrete -abstract continuum to a more concrete visual level.
convey a concept or topic by showing something else and implying a similarity. Teaching about electrical current by showing water flowing in a series of parallel pipes is an example of using analogical visuals.
It shows the qualitative relationships among various elements. Common examples include classification charts, timelines, flowcharts and maps.
communicate quantitative relationships. examples include bar and pie charts or line and pictorial graphs.
illustrate movement or change in time and space. examples include an animated diagram showing how to perform a procedure such as tying a shoe-lace, a line drawing with movement indicators or an animation of the water cycle.
illustrate theoretical or abstract relationships. examples include a schematic diagram of an electrical circuit, the food pyramid, or an evacuation plan.
