Content and Language Integrated Learning (CLIL) is as full of challenges as it is of possibilities. We will explore the challenges while seeking realistic solutions as eight Computer Science professors teach their subjects through English for the first time. We hope to gain insights into the bilingual classroom at the university level where teacher training can aid in professional development. Kevin Haines (2017) has posed the question about policies, principles and practice in bilingual settings, suggesting that we still need to address the challenging question: "who will support the teachers?" In this paper we will observe problems and solutions to bilingual teaching from the ethnographic point of view of action research. We hold that research in education must make the move toward a more qualitative assessment. As researchers, perhaps we need to describe less and "do" more by putting our research into action.
