Types of Learners

In class, we have been talking so much about testing and how it does appeal to all types of people and learners in the classroom. So then I think we all begin to ask, are there different types of learners out there and as future teachers how can we appeal to these types of learners? I found an excerpt from a book that discusses the different types of ways most students learn, and I think they are pretty common and have been heard before.

I thought it was interesting how it mentioned to keep in mind that you need to be flexible to each student's needs, whether they learn through vision, hearing, doing, or reading/writing. This can be heard as a teacher because all these students need very different things to get the most out of a lesson. As educators, we want them to get the most out of the lesson and apply it to their skills and everyday lives. Ultimately, that is the goal of teaching.
I think we can apply this to testing too. Not all people who are intelligent can excel the most with multiple choice questions and black and white answers. Similarly, not everyone is good at writing, or avoiding the black and white and talking about the gray areas, or even thinking strategically to do well on a test. But this does not mean that they are any less than another "intelligent" person. As we are flexible with our teaching styles to the best of our ability, I think we should also be flexible with our testing styles to the best of our ability.
