His research and teaching seek to further the scientific understanding of learning through an engagement with the design and implementation of learning innovations in designed learning environments including universities, schools, online, workplaces, and science centres. He has a particular interest in the how expansive or 'mind-body-world' theories of learning may be effectively applied in different settings; how they might be used to improve learning in science, technology, engineering and mathematics (STEM); and the impacts of public policy on expansive approaches to learning. To conduct this work he draws on design-research methodologies and on ecological theories of mind and society. Through this work, Simon's ambition is to contribute to a new kind of cognitive scientific collaboration involving neuroscience, physiology, and social, cultural, and technological studies in about equal measure.
