Two classes of third year students of the gymnasium went through our seminar “How to write (about history) on Wikipedia?” During the interactive lesson, they looked into the “kitchen” of Wikipedia and were able to experience how such an encyclopedia is created, what its advantages and limitations are and how to best use it in their own studies. The seminar took place on 15 October 2021 as part of the Velvet at Schools event, which we joined last year with WMCZ. Schools can still book this seminar, and we also offer a more practical workshop for smaller groups.
