I have previously freely admitted that I am a dinosaur when it comes to modern educational thought. I believe that you learn to be a good teacher by doing the job by observing those around you, choosing/having a mentor or role model like Mrs. Gruis (my 5th grade teacher) or Mrs Askegaard my 6th grade teacher or the tough but fair teachers in my hallway my first year..
The ubiquitous In-service that teachers are now subjected to often on a weekly basis is where you may occasionally learn some new techniques but more likely are subjected to a one-sided sales pitch for the latest short-term educational fad. A pitch often preached to the choir by one of their own. You may learn more about being a technical teacher in college or in an in-service but in the classroom is where you learn to be an educator.
I also believe that it probably takes most of us at least 5 to 6 years of classroom experience before we more fully learn our job ( that process is never complete) and at the same time learning self-discipline and discipline techniques that allow us to start taking the matches away from kids instead of putting out the fires or accidentally starting some new ones of our own making.
Hoping that all you teachers have a matchless week.
