POK stands for Polimi Open Knowledge: it is the MOOCs (Massive Online Open Courses) portal of the Politecnico di Milano that was launched in 2014. Since 2025, POK also hosts MOOCs from other universities and from the Higher Education in Art, Music and Dance (AFAM), as part of the Digital Education Hub 'Edvance' (https://www.edvance.it/).

POK's claim is 'MOOCs to bridge the gaps'. It expresses the strategy adopted by the Politecnico to:

• support students during their career;
• support upskilling and reskilling for professional growth;
• promote teaching innovation in both higher education institutions and schools;
• promote academic social responsibility (opening up the expertise of Politecnico di Milano for the benefit of a general audience, promoting conscious citizenship in compliance with the third mission of universities).

To this end, we classified the courses by six thematic patterns.
