Gardner’s Multiple Intelligence (MI) Theory is very useful for instructional designers. Integrating this theory on a web design provides instruction that meets learners' learning styles.
According to Gallagher, “Lessons incorporating intelligences is a process of learning how to use, trust, and interpret each of the intelligence capacities during a task. It involves knowing, understanding, and teaching by highlighting specific intelligence capacities” (Gallagher, p. 6).
For an instructional designer, knowing some of these traits could be important when designing a lesson.
Therefore, it is important to use a variety of strategies in instruction in order to maintain learner focus and accommodate different learning styles, as some students may learn better from a video, while others may learn better from visual guides.
