  • 隨著網路科技的進步,電子郵件已成為語言教學界新寵,並被視為一有效的溝通媒介,因此廣泛地為教師及研究者所採用。過去的研究中指出,交換電子郵件對學生的英語寫作能力有所裨益,但極少數提出事實佐證;此外,過去實驗對象多為大學生,其結果難以推及其他年齡層次的語言學習者。因此,本研究旨在探索電子郵件對高中學生英語寫作能力之影響,並援以實例加以佐證。
    在本實驗中,28位北市某高中學生隨機與大學外語系所學生配對,自2002年9月至12月,每對於14週中各交換8次英語電子郵件,郵件依據每週研究者所提供的題目撰寫。除電子郵件外,本研究資料來源亦含期初與期末的課堂寫作各一,及期初與期末的問卷調查。為研究電子郵件對學生寫作的影響,高中學生的第二及第八封電子郵件和兩篇期初與期末課堂寫作,皆以ESL Composition Profile及T-unit analyses加以評分與分析,並以t-檢定檢驗是否達顯著差異。

    結果顯示,以電子郵件作為寫作訓練之主要途徑,可以促進高中學生的寫作能力,尤其當寫作情境於課堂中時,學生的寫作在內容、組織、文法、句型複雜度及總分皆有顯著進步,唯一退步之處在於總長度。而其電子郵件寫作則在內容、組織、文法及拼字、大小寫等方面有小幅度的成長。此外,由問卷結果得知,高中學生對電郵交換活動及其影響持正面看法,在活動過後,學生對英語寫作的信心稍增、焦慮稍減;與高中生相較,大學生則顯示出較低的活動參與興趣,不過,同時也表示電郵交換增進了其部分寫作能力。

    以上研究結果證明電子郵件可促進高中學生寫作能力,但為使電郵交換活動的進行更加順利,建議教師可於活動前與進行中採取數點措施,如:為不熟悉電腦與電郵的學生進行活動前教學、為學生選擇適合的筆友、及早列出活動時間表、留下教師聯絡方式、與對方教師保持良好聯繫、提醒學生使用E-mail politeness rules等,此外,雖然學者們對於是否應為每週電郵寫作設定題目意見不一,依本實驗結果看來,題目設定仍有其必要性,但可配合以彈性條件,如每週給予一個以上的題目,或活動中空出幾週不設題目,讓學生有更多空間。

    對於未來相關研究,本實驗提供五項建議:一、除對寫作的影響外,電子郵件對其他語言學習面向的影響應再加以探討;二、筆友間的鷹架式學習支援(scaffolding)應可加以深究;三、可將交換電子郵件與其他活動融合,以增進雙方溝通的動機;四、應將學習者個人因素,如:不同學習策略納入考量,探討何類型的學習者較適合施以電郵交換活動;五、為更全面了解電郵或其他活動對學習者的影響,未來研究應同時於問卷及學生實際表現中收集資料,以免產生誤差。


    Abstract
    With the rise of Internet technology, e-mail exchange has become a popular pedagogical task and is regarded as one of the efficient communicative means, and thus adopted by lots of language instructors and researchers. Many studies mentioned the possible effect of e-mail exchanges on students’ writing skills, but rare support was provided by empirical investigation. Further, the findings from most previous studies could only be generalized in the college context. Therefore, this study was conducted to provide evidence for the effectiveness of e-mail exchanges on writing of EFL senior high school students through empirical textual analyses.

    In the present study, 28 senior high school students were paired randomly with a group of college English majors. From September to December 2002, the 14 dyads exchanged weekly e-mail based on assigned topics for 8 times in a 14-week period. Besides e-mail writing, pre- and post-project in-class compositions were collected. To investigate the writing development in senior high school students’ e-mail and in-class writing, two types of measurements were used to analyze students’ 2nd and 8th e-mail entries, and the two in-class compositions. The revised ESL Composition Profile (Jacobs, et al, 1981) analyzed students’ writing in content (30%), organization (20%), vocabulary (20%), language use (20%), and mechanics (10%). The t-unit analyses (Hunt, 1965) analyzed the writing data in terms of length, accuracy, and syntactic complexity. T-tests were used to compare the mean scores in each subcategory. In addition, to investigate the background information of the subjects, and whether both of the less capable learners, the senior high school students, and the more capable learner, the college English majors, felt positive about the e-mail exchanges project, a Background and an Evaluation Questionnaires were used on both groups before and after the project.

    The results showed that e-mail exchanges as a main component of writing training facilitated senior high school students’ overall writing ability, especially in the in-class writing context. Students’ in-class writing progressed obviously in total grades, content, organization, language use, and syntactic complexity, while the decrease only occurred in the total length by words. And their e-mail writing performance was also slightly enhanced in content, organization, language use, and mechanics. Furthermore, the senior high school students felt positively toward the project and the effects on their in-class writing ability. They also showed slightly more self-confidence in their own writing ability and less writing apprehension after the project. As for the college key pals, although they were less interested in the e-mail project than the senior high school students did, they perceived some positive effects of the e-mail exchanges project.

    According to our study, the instructors are recommended to take some steps in advance to make an e-mail project more efficiently. For example, holding a training session for students who are not familiar with computer and e-mail, selecting appropriate key pals for students, manifesting the schedule in advance, leaving the e-mail address of the instructor/researcher for the students, and keeping connection with the instructor of the key pals. Besides, to prevent writing block, it was suggested to survey students’ favorite topics, and then provide more than one topic for e-mail writing every week, or the instructor could leave some weeks for students to select their topics freely.

    For future studies, four suggestions are provided. First, effects of e-mail beyond the writing skill should be investigated. Second, the effect of scaffolding can be analyzed further. Third, an e-mail project can be incorporated with some other tasks to increase subjects’ motivation. Fourth, the connection between individual learner variables like learning strategies and the preference of e-mail exchanges should be emphasized. At last, to link students’ actual performance and their perceived improvement, future studies were suggested to collect data from both the self-report questionnaires and students’ actual performance.
