The quantitative and qualitative data were gathered by soliciting participants' attitudes towards English for Specific Purposes writing through (game)-based differentiated instruction, assessing their academic and professional writing, and debriefing their insight into how differentiated instruction might enhance English for Specific Purposes writing.
