A/HRC/19/77 Working Group encourages Governments to develop creative educational tools to promote appreciation of diversity among youth. 130. The Working Group emphasizes the important role of formal and non-formal education for deconstruction of prejudices, positive change of negative perceptions, enhanced understanding and social cohesion. To this end, the Working Group encourages States to implement educational activities and measures including human rights training at various levels and sectors to prevent and combat effectively racism, racial discrimination, xenophobia and related intolerance. 131. The Working Group encourages States to promote accurate reflection of history in education so as to avoid stereotypes and distortion or falsification of historic facts, which may lead to racism, racial discrimination, xenophobia and related intolerance. 132. The Working Group notes the complex linkages between education, identitybuilding and outbreak of conflicts. In this regard, the Working Group encourages Governments to ensure that textbooks and other educational materials reflect accurately historical facts, as they relate to past tragedies and atrocities, in particular those falling under the categories listed in paragraph 99 and other relevant paragraphs of the DDPA. 133. The Working Group encourages the Office of the United Nations High Commissioner for Human Rights to assist stakeholders to provide human rights education or training with a strong anti-discrimination component for students in schools and universities, journalists, state officials, civil servants, judges, law enforcement officials and military personnel, humanitarian workers, staff involved in peacekeeping and peace-building operations, as well as for teachers, trainers and other educators and private personnel acting on behalf of the States. The Working Group notes the importance of focusing on effective prevention of racism, racial discrimination, xenophobia and related intolerance during such trainings, in accordance with the provisions of ICERD and DDPA. 20
