During the first half of 2017, four scholars who know English-medium instruction (EMI) well and view it from different perspectives took part in a round-robin exchange. The forum contributors answered six sets of questions on aspects of EMI: defining terms; learning English in an EMI environment; the political or policy framework; learning a subject in a second language; teachers working in a second language; and EMI and multilingual education. Below is a summary of their answers (a longer version can be found in the online version of this Forum as supplementary content). The questions were devised and the responses edited by Philip Shaw.
