It is getting a little embarrassing, but I am about to bring another seven-item list to your attention. The variability in the contexts of higher education is staggering. As a starting point, we might consider variability due to disciplines, curricula, institutions, faculty characteristics and student characteristics. And yet, the principles were intended to apply to all of undergraduate education in the U.S. and to be based on solid research findings. I have even seen people claim that the principles can, with slight modification, be applied to graduate and professional education.
Good practice encourages contacts between students and faculty.
The most valuable contacts seem to be those that focus on intellectual interests, value issues, or future career concerns. Most folks who have written about the seven principles have focused on student outcomes. It strikes me that this principle also has implications for faculty members' satisfaction. I find it a lot more fun and rewarding to teach when I know my students, or at least some of them, personally. Good practice develops reciprocity and cooperation among students.
