To follow up on the topic of education, our weekly extensive listening feature turns on a very different type of educational model, that of Khan Academy.
This is the way this CBS 13-minute segment starts:
"Take a moment and remember your favorite teacher - now imagine that teacher could reach, not 30 kids in a classroom, but millions of students all over the world. As we first reported last spring, that's exactly what Sal Khan is doing on his website Khan Academy. With its digital lessons and simple exercises, he's determined to transform how we learn at every level. One of his most famous pupils, Bill Gates, says Khan, this "teacher to the world," is giving us all a glimpse of the future of education."
Watch the segment, which CBS released in early September last year as part of the programme 60 minutes, and find out the ins and outs of Khan Academy and its founder, 35-year-old Sal Khan.
