Teachers in their practice make choices grounded in their teaching experience resulting in what could be labelled design solutions. An identified problem is that these design solutions stay at the level of individual solutions and do not reach the teaching community. The aim of this article is to study how teachers´ design solutions can be systematically captured, organized, and communicated through design patterns and a pattern language. Building on participatory design we have together with teachers used and adapted the concept of design patterns and pattern languages as a way of capturing, documenting and communicating design problems and solutions to these. This structured approach led to the teachers seeing connections and interrelations between problems, and that a solution to one of these also helped in alleviating other problems. The formulation of design patterns and proposed pattern languages thus gave the teachers an overview of their practice that would otherwise be difficult to obtain. The content of the design patterns show what problems that are dealt with by the teachers through their design solutions. The structure of the final pattern language shows how problems and solutions are connected to larger goals for the teachers, such as improving the communication with students, as well as the importance of sharing good examples between colleagues.
