Background: Biophilia is becoming an important theme in contemporary design practice. Research in this area has demonstrated measurable improvements in human health and wellbeing when built environments are able to connect people to nature. However, there is much debate about how design students can best learn to fluidly implement biophilic principles in their work. Purpose: This article describes an action research study conducted by design educators to evaluate experiential learning techniques in health care-focused interior design studio courses. The goal was to improve students' creative synthesis in applying biophilic principles. Methodology/Approach: The author followed the four steps of action research--planning, action, observation, and reflection--in developing and evaluating a new experiential learning framework. An observational approach was used to assess student projects and the effectiveness of these teaching methods. Findings/Conclusions: Students who participated in the experiential learning activities demonstrated a relatively higher degree of holistic integration of biophilic principles in their design projects. Implications: While the observational findings are provisional evidence, these results provide insights into the advantages that experiential pedagogies may have in helping students to integrate and apply design knowledge. The ability to connect biophilic design principles to direct personal experiences appears to enhance creative synthesis in student work.
