Thank you all for the great suggestions. I spent another day in class (I'm still observing other instructors) and made the decision to be called Ms. Martinez. While I'm more comfortable being called by my first name, there are several reasons I chose to use my last name. Mainly, as I stated in a separate post, I am a fairly young instructor and given my height is that of preteen, I feel I must assert my leadership role at every opportunity. Sort of my Napolean complex, I suppose. Thanks again to everyone who took the time to respond.
