What does it mean to know something about history? If you know “your” history, what is it that you know? For many, it is definitely about being able to provide dates, to state what happened or how people lived in the past; while for others it means being able to conduct genealogical research or being able to navigate in a video game that takes place in an historical environment. In a school context, the issue of knowledge is always central. Pupils and teachers meet in, around and through knowledge, and moreover, knowledge is assessed daily. This article addresses how pupils in the last years of the nine-year period of Swedish compulsory schooling regard knowledge about history. The aim is to investigate how Swedish 15 years old pupils in Grade 9 describe knowledge about history, as well as what type of knowledge about history pupils appear to hold.
