The main purpose of this study is to investigate the unintentional learning that happens during the use of computer games. With the use of interviews with students in the ages 13-15 who all have played the game series Assassin’s Creed, and then compared them with students who does not play the game, we have been able to identify that some learning is taking place, but that the student’s attitude towards the subject, and their maturity, also is vital for the learning. Even tough, the students who didn’t really enjoy history as a subject showed better knowledge after playing the game, than the students who hadn’t played at all, which indicates that computer games can be a good source for learning. Another purpose was to investigate the students’ attitude towards using computer games in their education. Interestingly all the students we interviewed, even those who are not interested in computer games were positive to the use of computer games in some form in their education, either themselves playing, or the teacher using it as a form of interactive media to show a certain event or person. Our conclusion shows that computer games are a good source of learning, and the use of computer games as a pedagogic tool in the education definitely should be a subject for further research.
