Common wisdom dictates that in order to learn a complicated skill, it is best to break the skill down into parts, conquer simpler steps first, and then incrementally move forward, eventually getting to the hard stuff. For example, you don't just tackle a multivariable equation, you start with easier examples. First, you learn to add, subtract, multiply and divide. Then, you learn how to solve 2x=8, then x + y = 7, and so on and so forth until you are aptly equipped to solve 2(5x + z) = 30x + 3y + 10. For those who made it all the way from fourth grade mathematics to senior year calculus, that's an eight-year journey, and, until now, a necessary one. But what if that's not the best or only way to learn something? New research suggests that diving straight into the tough problems first could actually be a better method for teaching children new skills.
