Instructional illustrations can seem disproportionately time-consuming or costly to produce, especially when words are so easy to speak or write down. So even when illustrations are viewed as important to have, they may be dropped for expediency. Their value to the learner is often underestimated. When money and time is allocated for developing instruction, it is a wise investment to have a fair proportion going to the design and production of illustrations. As Part 1 will demonstrate, the value of illustrations goes far beyond an aesthetic one.
Illustrations are often at the root of understanding and learning.
