Learning for all; what does this mean?

In Chapter 7 of The Third Teacher, it discusses how as teachers we need to adapt to our students. Learning for All does not actually mean Learning for All. It examines how it is more of a concept/dream than anything and this chapter gives insight oh how to approach and fulfill this goal.
All for one and one for all, thats how the saying goes, right? It seemed to work well for the Three Musketeers, but what about for teachers and especially students? Can we/should we apply this type of approach to teaching? Ever since we were young, our parents always told us how special and unique we were. They never mentioned that this applied to everything, even our learning style. Our learning style is just as unique or special as say, our personality, talents, and smile perhaps. Therefore, with so many different learning styles, how are we as teachers supposed to acknowledge and satisfy each individual learning style? One size fits all doesn't apply to this instance. There needs to be a balance between both of these and that is what this chapter acknowledges.
Traditional curriculum offers, to an extent, a solution to thie dilemma. First, it gives teachers an objective; teach students the skills to understand the subject matter. Second, apply this to students with different kinds of learning styles. Simple enough, right? Well, suppose 2/3 of the class is fulfilling this objective. What happens to the 1/3 that is not? This is where traditional curriculum falls short. Why? Traditional curriculum is set up to accomplish many things while assuming the students are understanding without a problem. This is where the problem lies. There is no flexibility for the students who do not understand and they fall victim to it. This method indeed has invoked learning, but not for all.
Universal Design, and I'm not talking about clothing and what not, is an approach to the design of all products and environments to be as usable by as many people as possible regardless of age, ability or situation. What does this have to do with learning for all? Well, let's take the concepts of Universal Design and apply them to learning. We'll call it, Universal Design for Learning. Wait, it already exists. Universal Design for Learning takes traditional curriculum and makes it flexible. How can this be? Easy. It takes the curriculum but incorporates three vital principles; multiple methods of presentation, multiple options for participation, and multiple means of expression. Although this is not the answer for all students, it is however a step in the right direction. Now, there are options for the students and instead of adapting to the curriculum, the curriculum adapts to the students.
