Who Needs Schools?
We’ve mentioned the Khan Academy before, but there are three good reasons to mention it again.
- It’s so excellent.
- It has now been enthusiastically endorsed by Bill Gates.
- It has expanded its offerings.
What the site does is present short but elegant videos that clearly explain educational concepts. At last count, there were 1,630 of them, but Mr. Khan is aiming to produce a total of 10,000. The lessons were originally confined to math topics, but there are now videos on biology, chemistry, physics, economics, history, brain teasers, and much more.
