The goal of this qualitative study is to provide theoretical knowledge and design principles for a creative educational environment characterized by simultaneous study and exploration of science or math, and the arts: Write a Science Opera (WASO). To do so, we used a theory of creativity in education which links collaborative co-creation in creative activity, and identity: Wise Humanizing Creativity (WHC). Data were collected from teachers in interventions during which the WASO environment was implemented in two Norwegian primary schools. The topics of study were the multiplication table at the first school, and temperature at the second. Data relating to these participants' experiences and perceptions were coded and analyzed in order to articulate the kind of creative activity witnessed. The data, which consisted of interviews and reflective notes, were analyzed based on Educational Design Research (EDR) theory in order to explore design principles which could enrich WASO in the future, as well as to provide theoretical knowledge to other educational researchers.
