Having been on the faculty of several colleges and universities [as well as several pre-college schools], I really do not think there is any such thing as a "university type," any more than there is a "middle-school type."
I know university mathematicians who believe that K-12 education is important and who are interested in the curriculum, students, and teachers, and who are actively involved. But I also know of university mathematicians who care only about their own research and are interested only in a few colleagues researching the same narrow field, plus a few graduate students. They teach as little as possible and aren't even interested in undergraduate students, much less K-12 students.
I know university math educators who are excellent teachers, are involved in both preservice and inservice programs, and interact regularly with K-12 students and their teachers. But I also know some who are awful instructors, who don't keep up, and who haven't been out in the schools for 20 years.
In the final analysis, there are only individuals. This listserv is open to anyone. It exists for the purpose of discussing the NCTM Standards and related issues. But NCTM membership is open to teachers at all levels from preschool thru graduate school--a very diverse group.
So, if you have questions or concerns, ask and express them. If you have opinions, give them. If you have ideas or experiences, share them. Of course there are other listservs--a plethora. But if you want to discuss the Standards, I really think this is where you should be.
