The values of inclusion and active citizenship that Europe has always promoted have built a diverse society where multiple religions, cultures, and ideologies coexist. However, in recent years, due to the serious migratory crises and conflicts ongoing around the world, hate ideologies, radicalism, and hate speech that threaten coexistence have permeated a large part of society European, especially students, because they are more susceptible to them.Secondary classrooms are becoming polarized at an alarming rate, with a very worrying growth in the marginalization and violent radicalization of students, regardless of their origin or culture, which can lead them to fall into hate ideologies, which threaten EU’s bases from multiple spectra, but also generate educational disadvantages in these students that usually lead to their inexorable educational failure, not achieving higher degrees, and relegating them to marginality, facilitating their exclusion.Ending these outbreaks and promoting the values of citizenship, respect, and coexistence must be one of the main functions of teachers in high school classrooms, as it will allow the success of all students (including children of migrant origin and diverse cultures or religions) by reinforcing the collaboration between them, but also between the different agents inside and outside schools, and promoting preventive and early intervention approaches through collaborative and holistic approaches to learning and teaching.However, teachers do not have enough support or resources to promote effective inclusion in their classrooms, nor to detect hate speech and fight it in time. There are few educational materials that specifically tackle violent radicalism in the classroom and promote inclusiveness, and none of them have been created from a multicultural perspective (incorporating the experiences of victims of the consequences of radicalism) and through shared leadership, where students are directly involved in an equal position to combat racism and exclusion.Thus, this partnership is comprised by CCIV and INTERED from Spain, NJINGA MBANDE and PONTES from Italy, and EFOMW from Belgium, which integrate schools and Muslim cultural organizations from different countries of Europe. We will create truly impactful results within this project to enhance diversity and peaceful coexistence in the classrooms through shared leadership and solidarity among classmates, both inside and outside the classroom, creating a sense of respect and support that overcomes cultural, religious, and social barriers.Through the project “DIALOGUE, EDUCATION, AND RESPECT IN THE CLASSROOM: THE ROAD TO A PLURAL AND DEMOCRATIC EUROPE” and 24 months of hard work, entities from 5 European countries will develop 4 Transnational Meetings, many virtual and on-site activities to generate a high quality Intellectual Output and various results:-The O1 - METHODOLOGICAL GUIDE TO MANAGE DIVERSITY IN THE CLASSROOM THROUGH SHARED LEADERSHIP: this guide will train teachers on how to detect hate ideologies in the classroom and fight them through attitudes, didactics, dynamic units…-EDUCATIONAL MATERIALS TO PROMOTE DIVERSITY: a series of formal and non-formal educational materials to work on tolerance and diversity in the classroom and to drive young students away from radicalism and hate ideologies, including Teaching Units, OERs, and a group dynamics.-MANUAL OF GOOD PRACTICES TO MANAGE DIVERSITY IN EXTRACURRICULAR ACTIVITIES: this manual will provide specific guidelines to instructors to work on inclusion and diversity and to detect outbreaks of violence or bullying classmates and tackle these through dynamics, games, and the creation of collaborative networks among the students themselves.The Intellectual Output and educational results will be disseminated to dozens of schools in the participating countries thanks to the work of the partner and collaborating entities, which will carry out a powerful dissemination phase with multiple activities, culminating in a large Multiplier Event in Valencia (Spain) coordinated by CCIV. All this will allow this project and its results to have a great impact on high school students, effectively fighting hate speech in European classrooms, and reducing the possibi¬lity of many young people falling into the hands of radicals.
