Previous L2 writing research has compared rhetorical organization in L1 and L2 writing, focusing primarily on argumentative or persuasive writing. However, relatively few studies have compared different essay types in this context. Moreover, the classification of rhetorical organization has often been coarse. To address these gaps, the present study investigated how language (L1 vs. L2) and essay type (persuasive vs. expository) affect rhetorical organization of compositions written by Japanese EFL learners. Japanese university students composed both persuasive and expository writings in their L1 (Japanese) and L2 (English). The analysis revealed distinct patterns across languages and essay types, though the deductive structure was shared: (a) a structure where Collection and Comparison coexist was produced less frequently in L2 than in L1 writing, (b) a structure including only Collection was more likely to appear in L2 than in L1, and (c) persuasive writing showed a greater tendency than expository writing to include Comparison. These findings underscore the pedagogical value of focusing on comparison-related structures in L2 instruction, particularly through persuasive writing tasks.
