I don't know if you're familiar with the Earth Education Toolbook project. It is a collection of computer-based Earth science activities or "chapters". These are immersive units developed by teams of scientists and educators, and I think they are useful for upper-level high school (with the right computer resources) and undergraduate courses. Each chapter introduces one or more data sets or models, as well as an analysis tool that enables users to explore some aspect of the Earth system. You can read more about the offerings at the website: http://serc.carleton.edu/eet Shameless Pitch: Check out the just released chapter on climate change and climate modeling that we contributed to the EET: http://serc.carleton.edu/eet/envisioningclimatechange/index.html On Fri, Jan 29, 2010 at 10:46 AM, Dawes, Ralph <[log in to unmask]> wrote: > Julie and Others, > There is a big push, for example in California, for “digital textbooks.” > One reason is to save money – they are supposed to be a lot less expensive > than paper textbooks. > > Another reason is to take advantage of the Web for pooling and sharing > human knowledge.
