I don't question that before/after care workers do a great deal, but is creating lesson plans really the determining factor in whether one is a "teacher"? As a classroom teacher, I do that AND MORE.
In addition to creating lesson plans, I also create evaulations (written tests and other methods) to determine whether the children have reached the goals. I grade papers and projects at home. I make sure my students are learning everything on the state DPI's curriculum for my course, and I make sure my students are ready to pass the state end-of-course test. I provide special extras for the kids with special needs /IEPs /504 plans, and I provide extended curriculum for gifted kids who can go beyond the basic lessons. I provide after-school remediation (for free)for those who are falling behind. I complete mountains of paperwork for seemingly petty reasons, attend numerous meetings and trainings, and determine grades that'll be seen by colleges and scholarship committees. I write scholarship recommendations. I maintain an unbelievable number of grades, and I keep exruciatingly detailed records of attendance. I coordinate with guidance counselors, the school nurse, the social worker, and the testing coordiantor to make sure every child is getting what he or she needs. I am responsible for structure and discipline in the classroom. I maintain contact with parents, especially those who children are falling behind. I mentor younger teachers to help them set up rules and lessons that'll be effective in their own classrooms. I am required to sponsor extra-curricular activities and chaperone multiple school social and sports events on my own time.
Are we really doing the same job?
I agree that you're not a babysitter -- you're not in the same category as the teenager who comes around every couple weeks -- but, just as certainly, I don't think you're a teacher either. I think child-care provider or before/after school care provider is most accurate.
