This document discusses using electronic mail (email) feedback between instructors and students. It provides suggestions for using email feedback, such as using it regularly and before problems surface. Some advantages are that email allows for communication, sharing of information, and feedback without being restricted to a specific time or place. Limitations include potential lengthy or lack of responses from students, as well as private feedback being read by the wrong people or rude comments. The purpose of email feedback is to provide a simple and immediate channel for faculty to ask questions and students to respond about the class.
