美國管理協會於2010年時作了一項問卷調查，問卷結果顯示大多數的企業主管認為不管是現在或將來，批判思考能力、溝通能力、合作能力及創造力對企業組織而言都是最重要的4項技能。由於這四項技能的英語名稱皆是以字母C開頭，故被簡稱為Four Cs，為21世紀最重要的4個學習技能，而全世界的許多教育工作者也已經嘗試將此4項技能融入教學中。在本研究裡，研究者與一位國小英語老師合作，以一本英語繪本（How to Lose All Your Friends）為教材，設計3節40分鐘的課程，希望能同時教授英語及這4項技能。所設計的活動包括謎語、影片觀賞、朗讀、小組討論、找尋反義字、字詞分類活動、完成不完整的句子的練習、角色扮演、猜字遊戲及同儕評量等活動。為了檢視這3節課課程的影響，研究者以教師自製的語言測驗作為前後測，並以問卷調查、學習單、學生書寫的學習心得及教師訪談蒐集資料。研究結果顯示這3節課課程不僅幫助學生學習英語，同時也促進了他們的批判思考能力、溝通能力、合作能力及創造力。在文末，研究者依據本研究結果，提供對未來研究及教學實務上的建議。

In 2010, the American Management Association conducted a survey study and found that four skills (critical thinking, communication, collaboration, and creativity) are considered by a majority of business executives as the most important skills for their organizations today as well as in the future. These four skills are now known as the "Four Cs" of 21st century learning, and many educators all over the world have tried to incorporate the "Four Cs" into their instruction. In this study, the researcher collaborated with an elementary school teacher in Taiwan to design three forty-minute lessons for 6th-grade students based on a picture book (How to Lose All Your Friends) with the attempt to teach the "Four Cs" and English at the same time. A variety of teaching activities were implemented, including a riddle, video viewing, reading aloud, discussion, finding the antonyms, word sorting activity, sentence completion activity, role playing, a guessing game, peer assessment, etc. To examine the impact of the lessons, the researcher collected data through teacher-made language tests administered before and after the instruction, questionnaires, worksheets, students’ written reactions and interviews with the teacher. The data indicated that the lessons not only helped students learn English but also promoted their skills of critical thinking, communication, collaboration, and creativity. Based on the findings, the researcher offers some teaching suggestions to educators who are interested in designing and implementing similar lessons.
