Fylgja is a computer game for children created by the Mölndal City Museum to bring ancient worlds to life. It takes place at two archaeologically unique sites in Kållered, Mölndal. The project was originally called Time Travel and has resulted in a high-quality computer game, where children can experience an adventure in the Bronze Age and Iron Age in a 3D environment. There is great interest from schools, students and teachers in using the game as part of their teaching. Through experience-based learning, students can immerse themselves in the teaching of antiquities. To make this possible, the museum now wants to supplement the game with educational material linked to the game's website and a special teacher's guide. The museum also intends to carry out a follow-up and evaluation of how pupils experience the game and what effects it has on teaching. The evaluation will be used to demonstrate results and to develop future games and educational methods in an interactive environment.
