I think that having an assessment in the begin of a school year will benefit the class as a whole. That way right off the bat, you know how you have to differentiate your lesson for the class. Their are a few different types of learning styles to test for, two examples are Gardner's multiple intelligences or the very basic auditory, visual, or kinesthetic. There are websites to do it on your own time as well.
Learning Style Exam
Once someone knows how they learn, it opens doors for them to excel better. As a student, I know that if I see something I will learn and understand it better as opposed to hearing someone explain how they did it. For a child this can be a huge game changer! By us using differentiated instruction, we as the teacher are learning how to access every students strengths of learning. This helps us realize that we need to change up lesson accommodate for each students needs. This helps us realize that all children do not all learn the same, this tells us that we need to work to think out all possibilities that would benefit a child during their learning processes. Our job it to help each child grow as a learner and keep each child to be on the same track. With differentiated instruction in the classroom this will help promote each child to reach their goals to move up to the next grade. A classroom is where learning never ends, we teach them but the students also teach us!
