MATHLASH: "Khan Academy may be one of the most dangerous phenomena in education today," declares Mathalicious' blog. Mathalicious is a site created by Virginia teacher, Karim Ani, that develops videos and curricula for teaching mathematics. His contention--that Khan's pedagogy is identical to the same old, boring teaching style that emphasizes procedures rather than conceptual understanding--has ignited a powerful debate over math pedagogy. Next up: former high school teacher-turned Phd student in math, Dan Meyer's passionate argument over how up-and-coming tech tools are changing math by turning it into equations that must be mastered. His gut punch: "At this moment in history, computers are not a natural working medium for mathematics." Our two cents? Love the debate. But surely the world is big enough for both approaches?
