Employ the use of several different bright-colored markers or chalk when writing notes on a dry-erase or chalkboard. Write words in bold letters and alternate the colors that you use when presenting new ideas to appeal to the visual learner's learning style.
Design charts and graphs to illustrate information. Venn diagrams, bar graphs, KWL charts, timelines and flow charts are all examples of graphic organizers that you can use when teaching visual learners. Again, use brightly colored markers to create these charts in order to grab the visual learner's attention and appeal to her sense of sight.
Incorporate books, worksheets and other forms of written material into instruction. If you're creating worksheets, vary the size, color and size of the font. If you're using pre-generated worksheets or books, allow visual learners to highlight pertinent information with colored highlighters.
Repeatedly show visual learners the information they are being taught. Use index cards to create flashcards and repeatedly show students the flashcards. Rewrite and review notes, charts and other written documents several times.
Encourage students to visualize what they are taught. Prompt them to imagine the information that has been presented on charts, on worksheets, in books and in handwritten notes.
Create a quiet setting in which to teach visual learners. Avoid interruptions and loud noises as often as possible, as noises can easily distract these learners and take away from their learning experience.
