This study investigates how sensitizing graduate L2 students about source-text use might affect their citation practices. Two summary writing tasks involving two similar published articles, one irrelevant and one pertinent to source-text use, were assigned individually to 16 graduate English language teaching students from Iran. After completing the tasks, the students participated in retrospective interviews about their source-text use. Recursive thematic data analysis indicated that while they were inclined towards more direct source-text use in the first summary, they opted for more indirect and academic source-text use that involved their contribution and interpretation in the sensitizing task. The paper discusses the significance of sensitizing students to source-text use.
