Who We Are



We are a tri-national, multi-lingual association of environmental educators who collaboratively create new ways to use laughter and playfulness in the classroom and the workplace.


Aliza Weller is the concept developer and co-founder of Intelligent Play. She is a global training Instructional Designer for a high-profile high tech company in Cupertino, California, where she creates learning curriculum for approximately 50,000 employees all over the world. Her central work is to help others develop courage, authenticity, and to aspire toward inner greatness and depth. She taught Zen meditation and yoga in maximum security men’s prisons. She created urban programs that catalyzed policy change and galvanized 30,000 students to walk and bike to school to improve their health and that of the environment. She lived for three years in the high Canadian arctic circle, doing cross-cultural resource management work, where winters have 24-hour darkness and -70 temperatures. With a background in Education, Communications, Biology, Law, and a Masters degree in Environmental Studies, Aliza advises on the Board of Directors of the North American Association for Environmental Education and the Canadian Network for Environmental Education and Communication. Her arctic writing has been nominated for national literary awards. She recently gave a TEDx talk about the importance of living with aspiration, which can be seen here.
