Multicultural education seeks to “affirm cultural pluralism within a culturally diverse society and in an interdependent world” (Bennett, 1999). Therefore, the authors helped a group of preservice teachers develop an awareness for and an appreciation of another culture by experiencing the biodiversity and cultural diversity in Costa Rica. Research has shown that such experiences will change a person’s perceptions, attitudes, and actions (Bennett, 1999, Sleeter and Grant, 1998). The teachers, who visited the rain forest, the pacific coast, and rural and urban areas, learned that biodiversity in the natural world can be a metaphor for the cultural diversity in the social world.
