Various studies and accumulated experience show that although many teachers perceive education for a shared life as an important topic for students, in practice they do not teach it in a systematic and structured manner. A major reason for this gap is the lack of tools to deal with the subject, which involves explosive and controversial issues. Working to meet this need, aChord in recent years has developed a psychosocial basis of knowledge, training tools and pedagogy adapted to the multiple cultures and inter-group tensions that characterize Israeli society. We have developed diverse models for professional development while creating a network of connections and partnerships with various parties in the education system. Resting on these foundations, we guide and train educators in various positions and educational streams to work with research-based psychosocial tools and practices to effectively promote education for shared life in schools and classrooms.
