This study examined the online exchanges of 28 pre-service foreign language teachers (14 in Russia, 14 in the US) as they discussed in English their opinions about cultural products, practices, and perspectives, and their study abroad experiences via voice-based telecollaboration. Informed by intercultural competence frameworks, a qualitative analysis of participants' oral exchanges revealed six intercultural learning moves performed by participants in order to develop their own and/or others' intercultural competence during interaction. A follow-up analysis of the intercultural learning moves that emerged in response to five purposefully selected discussion question prompts suggested that one prompt type--i.e. a combined Brainstorm + Reflection Question on Cultural Experiences--encouraged participants to make a higher number and a wider range of high-level intercultural learning moves. The study concluded with guidelines for developing discussion question prompts that are likely to promote the emergence of advanced intercultural learning moves via telecollaboration with global partners.
