Jaakko Stenros (who is continuing as a postdoc researcher in the ‘Ludification’ project) defended his PhD dissertation in May 9, 2015. The study is titled “Playfulness, Play, and Games: A Constructionist Ludology Approach” (University of Tampere). Miguel Sicart from ITU Copenhagen served as the distinguished opponent, leading the discussion to explore the relation of Jaakko’s research to some fundamental questions in play and game studies. In his conclusion, he gave credit to Stenros’ study, calling it “an unavoidable piece of work” for any future scholarship in this field.
