It was easier to learn from the old version. It asked, "How many radians in this circle?" and didn't reveal the answer right away, but made you step through hints. I don't remember the exact explanation it gave, but it made more sense and revealed what is a radian. The new site is flashier but the old one was more effective, at least for this segment.
