As part of the Erasmus+ program, last week we hosted Prof. Ewa Bagłajewska-Miglus and Prof. Doris Lütjen from Europa-Universität Viadrina, Frankfurt an Oder. The Professors conducted a series of lectures on teaching Polish as a foreign and presented the structure of the activity of their unit - Sprachzentrum, in which Polish is one of the languages taught. The plan for further cooperation between our units was also discussed.
