Will memorizing a mountain of related chess positions help you to learn? Have you spent untold time studying a chess idea and then found that you can't remember it in a game? Education research, says Kevin Cripe, has found that optimal learning is based largely on the structure of problem sets and your brain's ability to understand similarities and differences. In The Learning Spiral, the author contends that you will actually absorb the game's concepts faster with seemingly random but carefully selected puzzles than with traditional, step-by-step teaching techniques. The key is that this is closer to real-life chess play, where nobody tells you the “theme” of the position in front of you.
