There are 20 people consisting of 18 teachers and 2 executive stuffs who will be involved in the Gurpinar IMKB Technical and Industrial Vocational High School's European union project. We expect 2 teachers to be involved in the project from each following branches; English, Physics, Chemistry, Biology, Mathematics, Literature, History, Geography and Guidance. Positive behaviors are expected from teenagers as our future on their hand. However, the tendency to violence and crime rate in middle schools are continuously increasing. One of the most contributing factor to this teenager behavioral problems is family violence. Teenagers under family violence ask for help only to their teachers. Being a teacher in this critical situation, we should be able to assist our students by supporting them socially and physiologically. Therefore, our teachers should learn influential communication methods with students and their families, managing conflicts between students and efficient guidance methods. Moreover, we cannot find a solution to pretend our students being expelled from our school as a result of attendance policy. When a student is absence more than 10 days without excuse or 45 days with excuse, s/he is expelled regardless of her/his performance.. Pretending expelled students from violence and crime becomes more and more intractable problem. Therefore, our teachers need to learn the strategies and methods to increase attendance rate by increasing motivation of students. Another problem we have is the defects in our disciplinary punishment practice. Students may feel they are rubbish when they face disciplinary action without exploring reasons behind the violation and without analyzing the level of student recovery. To reduce disciplinary actions, we want to practice the penalty-reward method used in many European schools by learning behavioral management and early development psychology. Our project becomes very important at this level as it provides 2 weeks education in 4 different countries. By educating our teachers and executive stuffs, the quality of education in our school will be increased to the international level. We will be able to use international methods for analyzing the violence and practicing the results. This project reduces tendency to crime and pushes individuals toward education and social life which goes in line with one of Erasmus Plus priorities of "reducing early school leavers under 10%"..
