Lets face it, we live in a culture where left brain skills are valued in our schools, even though the right brained skills of creativity and problem solving are most needed by adults. Most of elementary school is spent in memorizing details and practicing processes. Since most young children learn in a more right brain way through action, pictures, music, and the whole picture, teaching in a left brained manner requires hours of ineffective, boring drill work such as filling in workbook pages. Some children naturally prefer to use their left brain (memorization, numbers, sequencing, listening to lectures). These children are the ones who do well in elementary school. The more gifted a child is physically (athletic), or visually (visual-spacial, creative), the further they will be from the prevalent teaching style of most elementary school teachers. These are the children who will have trouble learning to read. It is not that they are "defective" or "slow", but simply that they are not being taught in the way that they learn. Just as an orange is not a defective apple, these right brained children are not defective left-brained children. The solution is to teach right brained children to read in their natural right brain way.*
This isn't hard, in fact it is fun. It doesn't require special training, just a love for the child and an understanding of the types of learning styles that fit a right brained person.
