The lecture cycles of the Institute of Diversity Studies and International Relations are a publicly accessible continuing professional development programme. National and international experts give lectures on selected topics of language and intercultural education in an educational context (for instance plurilingualism, mother tongue teaching and integration of refugees) and are available to the audience for professional discussion after the lecture. Most of these lecture cycles are broadcast on regional live streams by the Styrian Directorate of Education or can also be watched live online. Video recordings are then edited and published on the PHSt website.
