The use of visuals are definitely important in instruction. Some learners absolutely need visuals, and then are are some who may not need it, but will still have added support from the presence of visual aids. It isn't merely enough to include visuals, the visuals must be purposeful and enhance and/or support the lesson.
The blog entry Instructional Design Training: Using Visuals to Support Learning and Performance outlines the different types of visuals that educators should consider when including them in instruction. This blog was not only in alignment with my feelings on the use of visuals, but also gave me much more to think about in the selection and purpose of visuals in lessons.
The blog you shared was interesting - I had no idea there were so many different "types" of visuals! This is definitely something that I'll be bookmarking and coming back to! Thanks!! :)
