Many see formal education as mostly learning facts and procedures. Of course we will forget these when we don't use them often. However, I think the goal of education should be deep learning of concepts. Although we'll forget the procedures and details, when we truly learned a concept, we will always have a good idea what the concept is about, what it means, how to apply it, and, most importantly, where to go to learn more about it. Of course, deep learning is difficult to teach and assess on a large scale, so it is easier to test for knowledge of facts and procedural skills and teach children to perform well on these kind of tests.
