The PBS Car of the Future program has a new format.
1. The material is "open" (Creative Commons Attribution-Noncommercial 3.0) meaning that they encourage users to remix the material.
2. Some of their content is contributed from audience.
3. The content also comes with a teacher guide which is very much in the old fashion way, (e.g. explains how petroleum is turned into gasoline). There is always a restriction that the program "can be used up to one year after program is recorded off the air."
Since this is open content, I suggest it would be much more educational if students are asked to add to and mix the content. Different group of students will tackle the problem from different angle. The web site already provides a very good example (the audio slide show of model of efficiency)
