Getting university faculty to embrace it is VERY difficult. NSF is interested in this development, and both NSTA and AAAS have developed guidelines for the public schools that involve integrating the sciences. They have written a newly published book that integrates all of the major science disciplines. It was tested in eight colleges and universities last year, and we used it this year in the first sections of our course. They also have published a lab book, although we have been writing our own.
Integrated science is a great idea for the students.
It is, however, not easy to do. We have used the team teaching approach, with the two faculty team members from different disciplines in the classroom all the time. This has worked well for the development stage, but I doubt that we can sustain this over the long haul. We took a few major themes, such as energy and how systems work, and used a variety of examples. I would be interested in hearing about other integration efforts.
