This session is based on the book, 25 Biggest Mistakes Teachers Make and How to Avoid Them. The premise of the book is that teachers can avoid making mistakes by being made aware of the mistakes of others. In spite of teachers� best intentions and research encouraging best practices, teachers all over the world make mistakes when trying to control student behavior. The need for discipline and control in classrooms is universal. How teachers respond to that need, apparently, also is universal�as evidenced by translation of the book into several languages. Teachers have power�power that can be abused or used constructively. This session will examine what happens when teacher power runs rampant and anger and frustration reigns; also, the consequent effects of the teachers� mistreatment of students and why it happens. Academic trauma, defined as a result of a significant emotional event that is caused by an aversive academic experience usually involving a teacher, will be explored. The motives of teachers who admitted to mistreating students will be discussed to find out why they did what they did as well as possible psychosocial student outcomes and recommendations for avoiding mistakes.
