Digital Nation, a PBS documentary, developed this website which has many features that demonstrate how to create an effective educational website.
First, this is a 90 minute television program, but on the web the viewer is given a variety of options for viewing the program. First, you can see the 90 minute program in total just like the television program. However, the viewer also can view the program in various other ways. First, the program has been divided up topically such that you can see the themes of the program such as living faster, learning, etc. Within each of these thematic areas, you can view all or some of the various segments. These range from 1 t0 4 minutes in length.
In short, you can watch the program in any order you want to and you can focus on those segments that are of most interest.
Within each of these thematic areas there are places to share stories, comments and discussion by the persons interviewed in the video and other interactive features. Here the program creases to be merely a passive process, but becomes a place to discuss these issues, explore these ideas further and find additional resources on the topics.
This seems to be a good example of what a class lecture could become-- a series of short comments on various themes around a larger idea that invite discussion and interaction among students and the public.
