Emphasize depth of learning rather than breadth

Traditional curriculum has stressed that children be educated on a wide variety of topics in each subject. The problem with this is, in the limited time available in most curriculums, children are often introduced to topics but there is no time for them to really understand them. New learning theory suggests that teaching for depth is more effective. In this way, children can take full advantage of the examples that are presented to them, and grow to really understand concepts rather than just glancing over them.
