How Everyday Things are Made: Spent the morning with my kids on this site. They loved it. Good example of learning with video/audio and limited interaction (“apply it” section). I'm reminded of how we are still in the early stages of elearning…and offerings will continue to be more sophisticated. My first exposure to the Web was a text only experience. Now, in a very short period of time, the browsing experience has become interactive, media-rich, and user-friendly (in many cases). We have the background of Web progression to direct our efforts in elearning…so it's safe to say that over the next five years, we'll see an exponential improvement in the quality of elearning materials.
For those times when you really want to do a factory tour and you don't have one handy.
