<p>It’s not the presence of part time faculty (many of whom are highly qualified and excellent instructors), it’s the ratio of part timers to full timers. </p>
<p>Frankly, for an intro level class, an engaged and enthusiastic part time faculty member might offer a better experience than would a bored fulltimer who has been teaching the class the same way for 15 years because s/he is more interested in doing research or teaching upper division students.</p>
<p>For specific instructors, ratemyprofessor and other sites include ratings of both part time and full time faculty…but these have serious flaws that are not worth derailing this thread for.</p>
