As many as 75% of children and adolescents report experiencing some sort of peer victimization, researchers estimate, with 10 to 15% experiencing more severe and prolonged victimization. It has been suggested that the mental health of schoolchildren can be undermined by repeated bullying at school and further exacerbated by having inadequate social support (Rigby, 2000). Researches has indicated that being peer victimized is associated with emotional distress, anxiety, and depression (Kochenderfer-Ladd & Wardrop, 2001). So, peer victimization and bullying (PVB) is one of the biggest problems that affects psychological and sociological well-being of students in their school times and future. Mediators and Peacemakers against Peer Victimization (MEPEV) project, as its name implies, has been created for developing long-term and sustainable solutions for PVB in schools by educating some students as peacemakers and negotiators. MEPEV project is innovative since it use peer-mediating in solving the problem. MEPEV primarily aims to transform the disagreements among middle school students into peace by means of mediator and negotiator peers, before they turn their disagreements into conflicts/violence. Secondarily, MEPEV aims to * support personal and social development of young people, providing opportunities to show their potential,* encourage young people to work together on a common purpose, * encourage young people's participation in democratic life and active citizenship awareness, Target groups of MEPEV are secondary school students, other students, families of students and teachers.Project partners were selected among the best alternatives by prioritizing schools, training centers, education related departments of universities, youth clubs etc. and experienced partners. Main working fields and countries of partners were also regarded secondarily. So, partners were selected as 1 local government authority, 1 university and 1 non-profit association from Turkey; 1 vocational high school, 1 association and 1 universty from Italy, Austria and Slovenia. Project coordinator and partners will use Project Management Institute's PMBok® Guidelines for effective project management. Particularly, time and budget management, risk and quality management and dissemination strategies management will be implemented by pursuing these globally accepted guidelines. Partners will prepare progress and financial reports in each 3 months, quality report in each 6 month during the project period. These will be done for time, budget and quality management. Moreover, an independent external expert evaluator will be subcontracted for evaluating the quality of all project outputs and activities.MEPEV is an innovative Project since it proposes to create peer-mediating solutions against PVB problem and since it will use new types of training materials in PVB education such as e-learning platform and educational games. MEPEV is also complementary to other Works and projects of the partners since all of the partners are working in education field and have some programs for bullying at schools. Specifically, ITT has a Erasmus+ Project in which they explore psychological affects of PVB and AMEM is a local government authority in education field which has substantial curricula and plans against PVB.Partners will do their best for ensuring optimum level of communication and cooperation among themselves. They will hold transnational meetings 5 times in 4 partner countries. They will use all media channels for uninterrupted communication such as e-mail group, telephone, Whatsapp, Skype, Twitter, Facebook and the Project website. Within the scope of MEPEV, partners will 1- analyze best practices in the World, 2- create effective training modules for students and teachers, 3- implement these modules to some number of students and teachers in selected schools, 4- produce peacemaking and mediating handbooks for students and teachers5- create an e-learning platform and conduct test trainings of it6- create an educational game and conduct test trainings of it7- create some academic publications and publish them in peer-reviewed journals8- organize 2 conferences in Turkey and 1 workshop in each of Austria, Slovenia and Italy.In order to increase the impact of MEPEV, partners will use all dissemination instruments like the Project website, TV and newspaper news, leaflets, posters, workshops, academic journals, Facebook, Twitter, Whatsapp etc. All partners will also use their connections in their locations and enhance the impact of the Project. Project website, e-learning platform and educational game will be accessible for 5 years. Furthermore, MEPEV results will be transferred to public and private schools curricula by using appropriate channels and maximum local public participation will be ensured for long-term sustainability of MEPEV project.
