SUBSTITUTE TEACHER K-12 (Current Employee) – Philadelphia, PA – May 13, 2014
Being a substitute teacher is one of the most difficult jobs. It is a wonderful way to gain experience in a wide variety of educational settings, but most days are in new environments and classrooms and students tend to show their worst behavior in the flux of change to their regular routine. That being said, substitute teaching is an excellent way to refine classroom management skills. Some schools embrace and welcome substitute teachers better than others. Educational culture and learning environments are vastly different between districts and individual schools. I am, without a doubt, a better teacher today than I was when I received my teaching certification. Each and every day, school, staff member, classroom, and student has taught me through experience and helped me become a highly effective teacher.
