This document provides an overview of Rational Emotive Therapy (RET) and guidelines for teachers to manage their emotions and thoughts when dealing with unruly classes or disruptive students. RET teaches that our thoughts directly influence our feelings and behaviors, not external events. The document outlines strategies teachers can use to change irrational or self-defeating thoughts into more constructive thoughts in difficult situations. It also provides language-based techniques for coping with negative feelings, focusing on solutions rather than problems, and defusing anger without blaming students.
