Abstract Although it remains controversial, machine translation (MT) has gained popularity both inside and outside of the classroom. Despite the growing number of students using MT, little is known about its use as a pedagogical tool in the EFL classroom. The present study investigated the role of MT as a CALL tool in EFL writing. Most studies on MT as a tool for L2 learning have focused on student postediting of the translation that MT provides; however, the present study employed a different design with students translating their L1 writing into L2 without the help of MT and then correcting their L2 writing using the MT translation for comparison. Text analysis of students’ writing outcomes revealed that MT helped to decrease lexico-grammatical errors and improve student revisions. Using MT for revisions also positively affected student writing strategies and helped them think of writing as a process. The interviews and reflection papers demonstrated that students viewed the use of MT during writing positively. This study found that MT can be a useful aid to language learning, but for it to benefit student learning, teachers must be aware of its limitations and provide adequate guidance to students.

使用机器翻译对 EFL 学生写作的影响

摘要 尽管仍有争议，机器翻译 (MT) 已在课堂内外广受欢迎。尽管越来越多的学生使用机器翻译，但人们对其在 EFL 课堂​​中作为教学工具的使用知之甚少。本研究调查了 MT 作为 CALL 工具在 EFL 写作中的作用。大多数关于机器翻译作为二语学习工具的研究都集中在学生对机器翻译提供的翻译进行后期编辑上；然而，本研究采用了不同的设计，学生在没有 MT 帮助的情况下将他们的 L1 写作翻译成 L2，然后使用 MT 翻译纠正他们的 L2 写作以进行比较。对学生写作成果的文本分析表明，MT 有助于减少词汇语法错误并改善学生的修订。使用机器翻译进行修改也对学生的写作策略产生了积极影响，并帮助他们将写作视为一个过程。访谈和反思论文表明，学生们对写作过程中使用机器翻译持积极态度。本研究发现机器翻译对语言学习有很大帮助，但要使学生学习受益，教师必须意识到其局限性，并为学生提供足够的指导。
