[quote=Anonymous][quote=pettifogger][quote=Anonymous]Some exercise of repetitive calculation patterns is helpful as an aid to long-term memory and improved fluency (reduction in speed and cognitive load) on the mechanical commutational bits. On a hard problem, a lot of the thinking is dead end brainstorming, which isn't the part the kid needs to remember. [/quote] What you're calling dead end brainstorming is the most valuable part of learning. Learning how to solve problems by exploring and trying various things is not only important in math, it generalizes to almost everything in life. It's not about what kids need to remember (which is very little) it's about recognizing, connecting, and putting ideas together.[/quote] Come on. People don't have time to re-derive all of math from first principles on every single problem. [/quote]
