From June 2-5, 2015, Quantum College history teacher, PhD student and lecturer at YSU History Department, Michael Malkhasyan, received the invitation to attend the seminar-conference in Belgrade, Serbia, organized by the Council of Europe, called «Shared histories for a Europe without dividing lines» (with a focus on «Teaching and learning history for preventing a conflict»). 30 IB teachers and university professors of the member states (Britain, France, Spain, Russia, Portugal, Greece, Serbia, Estonia, Croatia, Romania, Bulgaria, Turkey, Slovenia and Cyprus) attended the conference. Michael Malkhasyan presented both, YSU and Quantum College at the conference. The only representative of the seminar-conference from Armenia presented a noticeable lesson plan in his report submitted to the Industrial Revolution era of demographic changes («Demographic Transition in the Period of Industrial Revolution») in which, manifestations of multiculturalism and intercultural communication are reflected in the pattern of expansion episodes. He also participated in various discussions and working groups’ activities. "I appreciate the great importance of Armenian representative’s participation in such events, as they are often part of related topics, such as discussions on the Karabakh conflict, and the intervention representative’s speech is appropriate and proper," so speaks about his Belgrade experience, Michael Malkhasyan. During the conference- seminar, an electronic-manual presentation was held, named «Shared histories for a Europe without dividing lines». The book is placed on the website of the Council of Europe and is designed for use in Council of Europe member schools.
