"Our project, ""Friendship is a Treasure"", has been prepared in the aim of preventing peer bullying behaviour among primary school students, to reduce the anger and stress problem seen in the students and to develop good relations with each other. The problem of peer bullying is a common problem in almost every part of the world and in all levels of educational institutions. The solution to the bullying problem is possible with the right policies to be applied in schools when students are still young. Education intuitions and the project partners first came together in the eTwinning project ""The story of friendship"", ID 215985, established by the coordinator on 15.02.2020. The partner countries participated in the online survey of the coordinator on the extent of peer bullying in their schools. The Project partners are: Romania (the coordinator), Portugal, Latvia and two schools from Turkey. During the project 5 LTT activities will be carried out and short-term student groups will be exchanged. 4 students and 2 teachers from each country will participate in each of the LTT activities. Age range for participating students is 10-11 yrs old. Selection criteria have been established for the participating students: having self-care skills, having no ongoing diseases, having collaborative operation features, having the ability of expressing themselves well, and students who fulfil their responsibilities with the project completely and correctly will be selected as participants. Selection criteria have been established for the participating teachers: to have English proficiency, to be able to take responsibility for the students participating in activities, to be involved in studies related to internet security at school, to take an active part in the eTwinning projects, to participate in vocational development works. The content of LTT activities prepared includes: anger control, stress-preventive activities, mindfulness activities, peer mediation training, empathy literacy training, orienteering and outdoor activities to support collaborative work, child yoga exercises, in-class techniques developed on positive behaviour development and story writing activities that develop friendship awareness. Local activities include: creating anti-bullying attitudes in school, informing parents and school workers about bullying, conducting studies to strengthen good relations between students, writing screenplays, creating slogans, exercises to be applied with families to create conscious awareness. Primary school students are examined and activities are organized to address the interests and needs of students, the so called ""Generation Z"". The methodology to be used in carrying out the project is adopted as holistic. The reason we choose this methodology is to give active roles to all school workers, students and parents who are fighting against peer bullying, which is our project topic. Since peer bullying is present not only in the classroom, but everywhere, school staff other than the school teaching staff will be informed during the project activities. The parents of the students involved in the implementation of the project will be given the responsibility of practicing home exercises which include stress prevention and mindfulness. E-journal and empathy literacy kit for developing empathy will be prepared in digital environment to expand the project. Stress-preventive mindfulness activities, family participation exercises will be published in said digital environments. Social media accounts such as instagram, twitter, facebook will be created and events will be shared. Project website and blog will be created. Targeted results of the project are: the increasement of positive behaviors among students, the prevention of physical, verbal and social bullying against each other, and the development of a common anti-bullying strategy in the project partner schools. Schools are sacred places to teach children basic morals such as love, togetherness and sharing. With the implementation of our project, peer bullying in schools will be largely prevented and strategy development against bullying will be provided in the long term."
