Peace and respect to diversity are core values of the European Union and fundamental to the development of the individual and to ensuring social cohesion and societal welfare. In the context of a rapidly changing world and increasingly diverse societies, specific cultural skills and competences become more and more important for young adults to participate successfully and effectively in increasingly pluralistic and complex environments. Globalization and technology have brought many challenges to our societies, marked by their potential to deepen inequalities and thus lead to increase in social conflict, community and cultural identity-based tensions and unrest. Schools find themselves in the frontline of these challenges, as more and more classrooms are composed of students with increasingly diverse social, cultural, ethnic and religious backgrounds. The majority of researchers agree that creating a culture of peace in schools requires a holistic, multidisciplinary and multi-level approach, involving the entire school, all the learning environments and stakeholders. The project’s main focus is on developing a “whole school” approach to fostering the development of the necessary social, civic and intercultural competences through:-proposing an innovative and efficient methodology to assist schools in their effort in mainstreaming peace education through peace-responsive school policies and practices, i- Integrating peace education and respect for diversity through the curriculum and through teaching and learning activities, through the development of interactive and intuitive digital learning tools for schools that promote the acquisition of positive skills, values and attitudes in pupils. - develop the capacity of teachers in promoting peace and respect for cultural diversity among students. Supporting teachers and educators is one of the primary objectives of the current proposal as they need to create an athmosphere of trust and mutual respect in the classroom, and support all members of the learning community regardless of their cultural, social, ethnic or religious background.The most important results to be achieved in the end of the project are: 1. The Mainstreaming Peace Education Training Course for School Leaders and Administrators, aiming at providing them with the necessary step-by step guidelines for the development and implementation of peace promoting school policies and practices. 2. The Mainstreaming Peace Education Toolkit for Teachers and Educators aiming at developing their capacity towards promoting peace and respect for cultural diversity among students.3. The Mainstreaming Peace Education Guide for Parents and Families4. The Mainstreaming Peace Education Online Learning platformIn order for a whole school approach to peace and respect for cultural diversity education to be successfully implemented, all stakeholders participating in the learning community must be involved. For this reason the main target groups of the projects are:-School-headmasters and administrators, as they are responsible for the development and implementation of administrative, instructional and curricular policies and practices;-School teachers and educators who need to effectively translate their knowledge about peace and respect for cultural diversity into concrete learning approaches and activities, that can guide pupils to pursue peace as individuals and as part of the community.-School children and pupils who need to acquire the competencies and skills leading to cultural sensitivity and awareness, much necessary for them to be able to adapt to new cultures, new situations and new technological demands.- Parents and families, as apart from school, children acquire most of their knowledge, values, and attitudes at home, thus the necessity of the involvement of the wider community in the coordinated effort of creating and maintaining a culture of peace and tolerance.The tools and approaches that will be developed and used during the project will provide school leaders and teachers with a coherent but multifaceted methodology of raising awareness on important issues, and promote values, attitudes and skills conductive to peace and respect for cultural diversity.
