Wouldn’t it be better to hire science specialists?
A science specialist is a good idea if he or she supports the teachers. A science specialist is not such a good idea if it means that students go to a science room for science and then back to the regular classroom for everything else. Science is mystified a bit and made separate from the rest of the curriculum. The room doesn’t fill up with the trappings of science, and the learning environment is a little impoverished as a result. But, if the science specialist is the way you want to go, great. Good things can certainly happen. We have just completed a document to help people plan how to use FOSS kits in this multiple back-to-back environment.
