本研究將繪本運用於成人華語的非正式課程（課外免費教學），旨在透過成人華語學習者對於繪本運用於成人華語文教學的看法及其學習成效，了解成人華語繪本教學的可行性。為達研究目的，本研究採用探索性的研究，以需求分析、課堂觀察記錄與焦點團體訪談為研究工具，蒐集研究資料，作為分析及討論問題的依據。本研究先針對臺灣北部某國立大學之華語文教學中心中級以上之外籍成人學習者發放需求調查問卷，之後以中級程度為限，於該華語中心開設「繪本學華語」免費課，並對修課之學習者進行焦點團體訪談，探討其對成人華語繪本教學的想法與意見。 經過研究實施與資料分析，歸結研究結果如下：（一）有趣又有助於學習者語言能力的繪本教學活動亦適用於成人華語學習者，可見繪本教學不只是兒童的專利；（二）繪本教學能為學習者帶來語言認知、情意上的助益，並彌補正規課程的不足；（三）繪本運用於成人華語教學時，繪本適合與否主要取決於「語言程度」、「繪本題材」與「圖片色彩與畫風」，其中又以「語言程度」最為重要，優先於另外兩者；而就主題而言，與「生活」及「文化」有關的內容最吸引學習者；（四）受限於免費課課程課時短少、分散，且對學習者缺乏約束力與強制力的特性，繪本教學在語言新知與技能提升方面的成效並不明顯，但可作為正規課的複習與輔助教材；（五）繪本運用於中級成人華語免費班教學所遭遇的主要困難為：難以找到與學習者語言程度相符的繪本、過於分散的課型易打斷繪本情節的連續性、免費班學習者語言程度不一。 最後根據調查結果提出華語文教學上的啟發與後續研究建議，以供華語文教學者在成人華語繪本教學方面的參考。 / This study applied picture books to an adult CSL free course, aiming to investigate adult CSL (Chinese as a second language) learners’ perspectives toward using picture books in adult CSL teaching, and the learning efficiency through picture book instruction. The research methods adopted in the study include needs analysis, classroom observations, and focus group interview. The participants of the study are intermediate-level students from a Chinese language center of a university in Northern Taiwan. The results of this study are (1) picture book instruction with interesting and language skill enhancing teaching activities suits adult CSL learners; (2) picture book instruction can benefit adult CSL learners both cognitively and affectively; (3) When using picture books to teach adult CSL learners, the main concerns are language difficulty, topic choice, and the style of pictures; (4) as the instruction time for the adult CSL free course is short and scattered, and it lacks the mandatory and binding force, such picture book instruction does not improve learners’ vocabulary and grammars significantly; however, it may serve as a good supplementary or review course; (5) the three major challenges for picture book adult free CSL course instruction are choices of picture book to suit learners’ needs, short and scattered instruction time, and learners’ various proficiency levels. Pedagogical implications and suggestions for further research are included in the end of the thesis
