Sal Khan: Let's teach for mastery -- not test scores

10:49 minutes · Filmed Nov 2015 · Posted Sep 2016 · TED Talks Live

Would you choose to build a house on top of an unfinished foundation? Of course not. Why, then, do we rush students through education when they haven't always grasped the basics? The founder of online Khan Academy, Sal Khan shares his plan to turn struggling students into scholars by helping them master concepts at their own pace. (This talk is from the upcoming special TED Talks: Education Revolution, which premieres Tuesday, September 13 on PBS stations.)

At the intersection of bold new medicine and indigenous culture, pediatric cardiologist Franz Freudenthal mends holes in the hearts of children across the world, using a device born from traditional Bolivian loom weaving.

For the first time in history, the majority of American parents don't think their kids will be better off than they were. This shouldn't be a cause for alarm, says journalist Courtney Martin. Rather, it's an opportunity to define a new approach to work and family that emphasizes community and creativity. "The biggest danger is not failing to achieve the American Dream," she says in a talk that will resonate far beyond the US. "The biggest danger is achieving a dream that you don't actually believe in." Watch »

Quote of the Week

The 'new better off,' as I've come to call it, is less about investing in the perfect family and more about investing in the imperfect village, whether that's relatives living under one roof or just a bunch of neighbors who pledge to really know and look out for one another. It's good common sense, right? The most reliable wealth is found in relationship."
