This study documents the development, implementation, and evaluation of an overseas study programme on environmental education for teachers (Ermer, 2004). Using experience overseas and the power of the Internet, a hybrid course model was designed for the delivery of a 3-credit graduate course in environmental education. This involved 11 participants who completed a one-month online course prior to a travel component in Puerto Rico. Eight teachers from Puerto Rico joined teachers from Wisconsin for a 2-week study tour on island ecology and environmental education.
