本研究針對台灣EFL低成就學生之段落寫作，比較「直接訂正法」與「語意重述法」兩種寫作回饋之成效。本研究對象為台北市某高職學生，共56名學生全程參與這項從2009年9月到2010年1月的研究。進行修改寫作時，教師對實驗組使用「語意重述法」，學生比較原稿與老師保留學生原意但改寫成符合英文語法的段落，並將發現的文法錯誤記錄並自行訂正；對照組則運用「直接訂正法」，學生審視老師直接在上面訂正的原稿。經過看圖英文段落寫作的前測與後測、實驗組與對照組後測結果比較、以及針對實驗組的訪談，研究結果如下：(1)整體性評量上，「語意重述法」對學生改進寫作較為有效；(2)兩組中程度較差之低成就學生進步程度均優於程度較好之低成就學生，尤其實驗組之程度較差者進步程度猶勝於對照組的；(3) 「直接訂正法」對減少學生文法錯誤之功效優於「語意重述法」；(4)絕大多數參與者認為「語意重述法」有助增進寫作能力。論文最後討論此研究在教學上的意涵與提出對之後研究的建議。 / This study aimed to compare the efficacy of “direct correction” with that of “reformulation” on Taiwan EFL low-achievers’ paragraph writing. Fifty-six students in a vocational high school in Taipei City participated in this study from Sep. 2009 through Jan. 2010. When conducting revision activities, the teacher implemented the “reformulation” technique in the experimental group. The students compared the originals with the reformulated versions given by the teacher, and detected, recorded, and corrected all the grammatical errors mainly on their own. The control group received the “direct correction” treatment, examining their originals with the teacher’s corrections on them. With the pre-test and the post-test on a paragraph-length English picture description, the comparison of the post-test results between the experimental and control groups, and interviews with the experimental group, the results are as follows: First, in holistic rating, “reformulation” was more helpful than “direct correction” in improving the participants’ writing performance. Second, the low-achievers with lower proficiency benefited more from “reformulation” than those with better proficiency. Third, “direct correction” was more effective than “reformulation” in reducing the participants’ grammatical errors. Fourth, the majority in the experimental group were positive of “reformulation” as a way to improve writing. Finally, some implications for pedagogy and suggestions for future studies were made.
