If what you say in the beginning few paragraphs is true, how in holy hell did you get hired as a teacher. You admit, essentially, that you are totally unqualified for the job. Every classroom must, by law, be led by a Highly Qualified teacher. In other words, every classroom must be led by a teacher who has had formal training in classroom managment, child and/or adolescent psychology, behavior management, assessment and grading, year, unit, and lesson planning, etc. You should, for the sake of your students, tender your resignatiin untl you have been properly prepared to lead a classroom.
