I enjoyed this article - simple and to the point. An educator is only as connected as the technology he/she uses. While math formulas may not change, how the information pertaining to that math formula is disseminated has changed throughout the years. We've gone from an abacus, to pen and paper, to calculators, to computers, to tablets and smart phones. Educators today have to not only master their chosen field, but also technology ... and that is everchanging.
