This chapter reports on a qualitative investigation on the development of adult Spanish language learners' intercultural sensitivity while using Web 2.0 technologies to explore living abroad. Comments provided by 33 participants on wikis, Pinterest, and journal entries were analyzed using a line-by-line interpretative approach (Charmaz, 2006). Data analysis revealed that while investigating studying and living abroad using Web2.0 technologies, learners often remained in an ethnocentric stage of intercultural sensitivity (Bennett, 1993). However, upon the completion of reflective activities, many learners began to progress in their intercultural sensitivity, demonstrating a shift away from ethnocentric thinking.
