In this disseration, I would like to present a case study of my teaching practice as an English language teacher in a local secondary technical school. The case study focuses on the connection between students’ motivation and their behavior problems. The base of the framework of the study is Zoltán Dörnyei’s theory on levels of motivation. This theory provides a wide range of components which make it possible to search for an answer. First I will introduce the theoretical background on students’ motivation, then present the case study itself. Finally, I will provide solutions to the behavior problems.
