The Last Meeting was devoted to a discussion of what an excellent high school science curriculum should consist of. Naturally there are roadblocks. Most people promoting it are biologists so there is not much Physics content. This is no great surprise. It is mainly a course for non science majors.
Integrated science leaves out the kids who want to be science majors.
When many high school students trained in these programs get to college they are lost. We have two populations to educate. The Physics teachers get a crack at the kids in the first year and perhaps in the fourth if the student elects to take an elective. The reason for this is that there is a shifting toward high school of what should be taught in middle school. Similarly there is a shifting in college of what should be taught in high school.
