Recently a new national curriculum was introduced in Swedish grade schools. This study set out with the purpose to investigate how teachers have interpreted and perceived the new policy documents during their first year in action. The theoretical framework consists of Aristotle's qualification of knowledge which divides knowledge into three forms: episteme (scientific knowledge), techne (practical knowledge, skills, and crafts) and phronesis (practical wisdom). Through the lens of Aristotle's three forms of knowledge, we analyze the results of our semi structured survey which consists of both closed, semi-open, and open questions. The data consists of eleven survey answers by history teachers across the country. The results illustrate that teachers have interpreted and perceived the new national curriculum differently, and have, therefore, drawn different conclusions based on their different circumstances. However, the teachers seem to share a mutual understanding that subject knowledge is more emphasized in the new national curriculum. Most of the teachers devote time to practical knowledge in their lesson plans, but argue that the development of practical wisdom, however, is rather a spontaneously occurring form of knowledge that is not or cannot be planned ahead as easily. Lastly, the results of this study indicate that training, collegial communication, and consultation can have an impact on the understanding of a curriculum.
