During the preschool teacher training program, we study how we should counteract traditional gender patterns and gender roles. As future preschool teachers, we want to get more knowledge by studying how the counteract works in preschools. We also want to study how preschool teachers work with counteracting traditional gender patterns and gender roles, what one as a preschool teacher need to think about and how preschool teachers relate to the assignment. With the help of two research questions: How do preschool teachers interpret the assignment to counteract traditional gender patterns and gender roles? How do preschool teachers say the work to counteract traditional gender patterns and gender roles? We chose a qualitative method to collect our data. Qualitative interviews were made to get answers for our purpose and research questions. Literature and theses were also used to help analyze the data. Our results show that preschool teachers interpret the assignment to counteract traditional gender patterns and gender roles differently. We found that even though it is interpreted differently they work very hard to fulfill the goals of the preschool curriculum. The interviewed preschool teachers also work differently because of the different interpretations. We found that guidelines, in the curriculum, on how to work with the assignment would be helpful to reach the goal of equality in the preschool and society.
