This paper explores the use of participatory methods prior to designing interventions within a research project at a primary school in central Sweden. The approach presented in the paper is based on the principles of participatory design (PD), to enhance the use of these methods within the areas of educational research (ER), lighting, and architecture. This approach aims to include participants of educational spaces and incorporate their views prior to design interventions. Two workshops were designed to support teachers' participation through hands-on activities. Twenty-eight teachers participated in the workshops. Scale models corresponding to two of the school's classrooms were used to initiate discussions regarding the interconnection between spatial layouts, lighting, and learning activities. The workshops' data collection analysis assisted the research group in understanding the school's spatial and learning characteristics. The information gathered from the workshops provided additional knowledge and informed the research project in a way that allowed for further development and changes within the project related to the additional variables measured along with light. According to the analysis, there is a correlation between the activity and the desired layout of the space, while the type of equipment also varies according to the task.
