Salman Khan, renowned voice from the amazing library of 1,400+ online videos posted at the Khan Academy, speaks at GEL 2010. His talk focuses on how his accidental approach towards teaching online has struck a chord with students. While teachers are quick to say that classroom instructors can’t be substituted for by online videos, Sal wonders if that is really true. Among the many reasons discussed, perhaps the one that goes unsaid most often in classrooms is the intimidation factor. Peer pressure, eagerness to impress, and desire not waste others’ time can inhibit students from taking advantage of the benefits offered by personal attention. Several other factors Sal mentions that have led to success include him not appearing in the videos, keeping the video durations to 10 minutes, and the ability for students to pause, rewind, and jump around to topics in any order they desire.
