Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. In his talk, Dan Meyer shows classroom-tested math exercises that prompt students to stop and think. (Filmed at TEDxNYED.)
One bag of apples, one apple, one slice of apple -- which of these is one unit? Explore the basic unit of math (explained by a trip to the grocery store!) and discover the many meanings of one.
Salman Khan talks about how and why he created the remarkable Khan Academy, a carefully structured series of educational videos offering complete curricula in math and, now, other subjects. He shows the power of interactive exercises, and calls for teachers to consider flipping the traditional classroom script -- give students video lectures to watch at home, and do "homework" in the classroom with the teacher available to help.
Ayako Suwa is intent on spreading a new concept of food that evades labels such as gourmet and nutritional. She believes that to eat is to live, but we must taste to truly evolve, and those tastes include happiness, regret, anger and more.
High school science teacher Tyler DeWitt was ecstatic about a lesson plan on bacteria (how cool!) -- and devastated when his students hated it. The problem was the textbook: it was impossible to understand. He delivers a rousing call for science teachers to ditch the jargon and extreme precision, and instead make science sing through stories and demonstrations. (Filmed at TEDxBeaconStreet.)
