i want to be the best teacher pl give someguidelines?
I am a pre-school teacher and my advice to you is to have lots and lots of Patience. Try to remember that they are just children and take it from me it is hard  to do that at times(bless their little hearts)! Stay on their level and make their learning experience fun, fun, fun! Most of all, love them and remember they look up to you.
I personally liked to study outside (depending on the weather) either at a park or at the college.  It seemed that if I stayed away from studying at home, there were less distractions.  Also, turn your cell phone off, have a energy snack/drink, and make sure you have had enough sleep beforehand.  I just graduated with my Education degree and this is what I did!  Hope it works for you!
