In 1998, the Tulsa (Oklahoma) Metropolitan Ministry's Task Force on Religious Understanding, in partnership with the National Conference for Community and Justice, the Jewish Federation of Tulsa, and three local universities, began planning an interfaith study abroad experience in Israel for adult learners within the Christian, Jewish, and Muslim faith traditions. The planning committee envisioned an experience that would provide opportunities for exploration of the social, cultural, and religious symbols associated with the three faith traditions. The narrative of adult transformative learning became central to the study as a result of observing participants (n=45) in pre-trip meetings and during the actual study abroad trip. Group members participated in five mandatory pre-departure study sessions designed to educate members about the spiritual traditions and religious beliefs of the three faiths, as well as the political issues tied to these faith traditions. While in Israel, additional study sessions were conducted by spiritual leaders of the Islamic, Jewish, and Christian faiths. The group was administered three Likert scales in a pre-trip-post-trip format. Findings revealed that interfaith trialogue is an effective means of bringing about religious understanding. The narrative dimension of the trip was the most insightful because each person's faith tradition was challenged during the experience. The dialogue with others and the trialogue among the group members was not a linear process, but rather an incremental process of transformative learning. An opinion questionnaire is attached.
