University is where you learn that almost everything in school books is over simplified, out of date, or (periodically) just plain wrong. One of the benefits of having researchers teaching is that they have a better understanding of both the content and dynamics of their field. This is far different from primary and secondary schools, where teachers are usually teaching outside of their discipline. Even a high school physics teacher with a science degree is likely to be a biologist or a chemist by training. Of course, there are a multitude of other differences with university educations. For example: governments don't set the curriculum, which is hugely beneficial for fields like history. (Governments have a nasty desire to set the historical narrative.)
