Exploring the Efficacy of a Source-Based Writing Tutoring Intervention for Multilingual Students in the Writing Center

Source-based writing skills, which include evaluating, synthesizing, and citing sources, are skills that students are expected to acquire as part of college-level writing. Unfortunately, many multilingual writers (MLWs), especially those in advanced degree programs, lack programmatic support and instruction. Thus, writing centers represent a critical site to offer MLWs tutorial-based support. Our study examined whether or not writing centers can help MLWs develop—and transfer—source-based writing skills in a sequence of three tutorials. We recruited five advanced student MLW participants from different cultural backgrounds who were uncomfortable with source use. Through pre-and postwriting samples, interviews, writing process recording videos, and a long-term follow-up, our findings indicate that our three-sequence tutorial significantly improved advanced MLWs’ source-based writing skills and transferred to the next semester. Improvements occurred in the areas of selecting, organizing, and connecting sources as well as in engaging in appropriate source use and avoiding plagiarism, although some areas showed stronger gains than others. This study contributes to the field’s development of replicable, aggregable, and data-supported best practices to explore the efficacy of tutoring for specific populations. We offer suggestions for writing centers to develop, test, and create tutoring-based MLW support programs.
