"<< Background >>Partners in the DD@S project, Democratic Dialogue at school, share their vision, common ideas and approaches to handle difficult situations that originate in the context of sociocultural diversity at school. One of the greatest difficulties for teachers is the management of ""difficult"" classes. The term ""difficult class"" refers to a class with relational, emotional and communication difficulties, considering the relationships with pupils, between pupils and very often, with pupils’ parents. In the classroom, teachers experience difficulties in teaching themes such as homosexuality, terrorism, racism, religion, ... Peer support of colleagues in how to deal with potential intercultural conflicts at school is highly important. Specific dialogue skills, creating a mutual dialogue, can contribute to an inclusive educational environment that fosters a sense of belonging between school team, teachers, pupils and parents. But, teachers feel unconfident in facilitating dialogue about controversial themes. DD@S contributes in the professional development of teachers to acquire effective dialogue skills to cope with ethnic, religious and multicultural conflict situations at school. Partners within this project, believe in the strength of dialogue to tackle intolerance and discrimination at school to stimulate inclusive education all over Europe.<< Objectives >>The aim of the DD@S project is to strengthen European secondary school teachers in dealing with multicultural challenges at school. By developing a gamification based online training, the DD@S training, it provides a professional development training in dialogue skills. This method supports school teachers in reflective thinking, communication skills and dialoguing on controversial themes, such as religious or ethnic intolerance. Additionally, the project provides a toolkit, teacher modules with theoretical information, applied in good practices, a guide for implementation and policy recommendations about the preconditions for implementing DD@S at school.Eight partners out of 4 different countries collaborate in the project, emerging both theoretical frameworks with in-field applications and good practices from within the field of education. Crucial actors within the project are school teachers who participate and collaborate in the development of the project. As a result of the DD@S project, teachers in the participating organizations will feel confident in dealing with controversy and intolerance at school, more specifically, intolerance towards pupils, colleagues, parents or themselves. DD@S aims to directly address about 75 school teachers in each participating country. Additionally the project team has a large network that has the capacity to reach over 1000 schools per participating country for further dissemination of project results.<< Implementation >>In an international professional learning community of experts in democratic and intercultural dialogue, gamification based online learning and secondary school teachers, the DD@S project emerges. For the development of the toolkit, the teacher modules and the scenarios of the gamification based online training, the project team organizes surveys and interviews with secondary school teachers in focus groups. Then, a trial of the online training is organized with participating teachers and discussed for further improvement before the final version is launched.Learning, teaching and training activities promote exchange of expertise and good practices for the gamification based dialogue training, the toolkit, the teacher modules and policy recommendations. In addition, these activities train participants in the full project deployment of DD@S at national level in each country.Finally, within the broad network of the project partners and associate partners will disseminate project results at European level.<< Results >>The project results in dialogue competent teachers who feel confident in mutual dialogue in their professional lives, especially within a superdiverse school context.The project results are:a gamification based online training in democratic dialogue,a toolkit with tools and good practices, needed to implement DD@S in schools; including a content managed system and guide to help teacher teams in developping their own specific training cases;teacher modules and a guide for implementation;policy recommendations;Other expected project outcomes at individual level are an increase in awareness about the sensitivities of multicultural challenges at school. At microlevel, the project results in an effective coping strategy within the school team, for these challenges. This leads to a tolerant and inclusive school climate. On the long term, a tolerant and inclusive school climate leads to an increasement of well-being for all actors within the school."
