preserving your teacher's voice

Lea asked me on Friday to look into how one preserves one's teacher's voice, poiting out that
a lot of our colleagues eventually sustain real damage to their vocal chords.

I couldn't find much in Communication for the Classroom Teacher (or anything else among the rest of my stuff; I am not the best role model in this regard).

The thing to remember is the importance of limiting your talking in the first place; do lots of group work and don't try to talk over a group of boistrious teenagers.

other then that, check out this article in Teacher.Net about breathing techniques:

incidentally, Teacher.Net is an on-line teacher magazine with highly practical content (albeit U.S. based)
http://teachers.net/gazette

and while you're at it, you might want to check out the list of on-line teacher resources at:

or the Canadian teacher resources site:
