English 150: Expository Writing is an undergraduate course in expository and research writing offered by special partnership to both the students of Case Western Reserve University (CWRU) and the students of the Cleveland Institute of Music (CIM). The course provides student writers experience in the critical reading and writing practices required for engaging with and producing well-researched, well-organized, well-argued, and stylistically complex academic prose. Working to address the challenges presented by English 150 through collaborative teaching, the authors designed a course that would both offer resistant students greater investment in their writing processes and provide multilingual students with individualized instruction and extensive feedback. To this end, they created a "gamified" course curriculum. The authors envisioned their gamified classroom as a means to interact more closely with their students in order to address their diverse needs directly, and as a space in which students could teach and learn from each other, thus developing their writing practices through collaboration with peers.
