廣泛閱讀是一種閱讀教學法。研究證實廣泛閱讀不管是在母語學習或外語的教學上都有不錯的成效，因此也常被建議運用在閱讀教學上。近十年來，有越來越多研究顯示廣泛閱讀的確對外語的學習有很大的助益，若能妥善運用，不只能增加語彙知識，改善閱讀能力，還可以讓閱讀變成一種愉快的學習經驗，進而增進對閱讀的信心以及動機。也因此廣泛閱讀應融入在外語教學的課程中。本文同時也探討在課堂上運用廣泛閱讀教學可能會面臨到的問題。

Extensive reading (ER) as an approach to teaching reading has been shown to produce favorable effects and is highly recommended in first language (L1) and second language (L2) classrooms. Over the past decade, findings from research have provided further evidence of the benefits of ER for learners in foreign language learning contexts. An ER approach, if implemented under appropriate situations over some period of time, has been seen to contribute to L2 learners’ vocabulary knowledge, improve reading comprehension skills, make reading an enjoyable experience, and promote learners’ confidence and motivation in reading. Given the merits of ER, this paper argues that an ER approach can and should be incorporated into the foreign language curriculum. Challenges facing the implementation of ER in L2 reading classrooms are also addressed in this paper.
