The Khan Academy has about 3,200 tutorials on video, each about 10 minutes long. It attracts more than a million students a month. Initially, the content was mainly second-level maths. Maths is still the focus, but there is growing content on physics, chemistry and biology, as well as economics, humanities and fine art. The videos have been viewed more than 150 million times. In addition to videos, the academy resources include progress-tracking software, automated exercises with continuous assessment, and a range of aids for teachers. A dashboard tool allows teachers to see immediately how students are getting on, how many videos they have completed, how many questions they have answered and where they need help.
