Social-interactive Writing for English Language Learners (SWELL) is collaborative writing based on Topping's Paired Writing Method. The method was changed to meet the needs of English language learners. In both methods, pairs are formed according to proficiency, pairing a more advanced student (a Helper) with a less advanced one (a Writer). The author describes the steps of generating ideas, drafting, reading, editing, best copy, and evaluating. Features of SWELL include using students' linguistic knowledge (L1), balancing fluency with mechanics, and promoting explicit teacher instruction.
