教育部2015年推出的《大學英語教學指南》（以下簡稱《教學指南》）是指導我國大學英語教學新的綱領性文件。《教學指南》明確規定大學英語的教學目標是培養學生的英語應用能力，增強跨文化交際意識和交際能力，同時發展自主學習能力，提高綜合文化素養，使他們在學習、生活、社會交往和今後的工作中能夠有效地使用英語，滿足國家、社會、學校和個人的需要。根據我國現階段基礎教育、高等教育和社會發展的現狀，大學英語教學目標分為三個等級，即基礎目標、提高目標和發展目標。基礎目標是大部分在大學入學時已經或接近達到高中英語七級水平的學生應達到的基本要求。提高目標和發展目標是。
《教學指南》明確大學英語課程的特點就是兼具工具性和人文性。工具性指的是大學英語教學要注重培養大學生的英語聽、說、讀、寫、譯的能力和跨文化交際能力，並掌握與專業或未來工作有關的學術英語或職業英語，獲得在學術或職業領域用英語進行交流的能力。而人文性指的是大學英語教學要讓學生了解國外的社會歷史與文化，增進對不同文化的理解、對中外文化異同的意識。人文性的核心是以人為本，弘揚人的價值，注重人的綜合素質培養和全面發展。為此，《教學指南》提出大學英語課程要注重基礎性和應用性相結合，包含系統、開放、動態和立體的多門課程設置，課程內容應包括通用英語（English for General Purposes）、專門用途英語（English for Specific Purposes）及跨文化交際（Intercultural Communication）。
「21世紀大學英語應用型」系列教材力求體現《教學指南》的原則和精神，在編寫宗旨、單元設計、材料選擇、課堂活動和課堂練習的設計上力圖忠實地詮釋《教學指南》的各項指標。本系列教材為綜合英語類的必修課程教材，教材包括：
《21世紀大學英語應用型綜合教程（修訂版）》(基礎級、1—4冊)；
《21世紀大學英語應用型綜合教程教學參考書（修訂版）》(基礎級、1—4冊)；
《21世紀大學英語應用型自主練習（修訂版）》(基礎級、1—4冊)；
《21世紀大學英語應用型視聽說教程（第3版）》(基礎級、1—4冊)；
《21世紀大學英語應用型視聽說教程教學參考書（第3版）》(基礎級、1—4冊)；
《21世紀大學英語應用型閱讀教程》(1—4冊)；
《21世紀大學英語應用型長篇閱讀》(1—4冊)；
以及相關配套的語法、寫作、口語和大學英語四、六級考試輔導教材。
一、 編寫原則
1. 體現《教學指南》和四、六級考試大綱的原則和精神
本系列教材力求體現《教學指南》和最新《大學英語四／六級考試大綱》的原則和精神，在編寫宗旨、單元設計、材料選擇、課堂活動和課堂練習的設計上力圖忠實地詮釋《教學指南》和最新《大學英語四／六級考試大綱》的各項指標，開拓新時代大學英語教與學的新領域。
2. 體現現代信息技術與英語教學的整合運用
本系列教材建立在外語課程與計算機網路全面整合的基礎之上，充分利用現代信息技術，培養學生的英語綜合應用能力，尤其是聽說能力。
3. 體現課堂教學與測試的有機結合
本系列教材順應現行大學英語四、六級考試及四、六級機考改革的要求，在紙質課本練習和網路平台的練習設計上，覆蓋現行大學英語四、六級考試題型及四、六級機考題型，並緊密結合雅思、托福等國際化英語水平測試。
二、 教材特色
1. 主題新穎，選材獨特，抓取當代大學生的關注點，提升其學習語言的興趣
興趣是最好的老師，英語學習也是如此。本教材的單元主題是編寫者通過調查問卷廣泛徵求學生的意見，並根據時代的發展需要而確定的，即從學生學習的視角出發，而不是編寫者想當然地確定主題。因此單元內的主題和選材能夠吸引學生極大的注意，並引發熱烈討論，使得課堂教學生動活潑。
例如，針對絕大部分學生四年的大學生活都會遇到的「Campus Love」這個熱門而經典的話題，綜合教程第1冊的第2單元對此展開討論。Text A 「Cant Forget Your First Love」講述初戀對一個人一生的影響，提醒大家珍惜和正確對待初戀。而Text B 「College Dating Tips for Student Couples」集中討論大學生應如何處理校園愛情和學習生活之間的關系。這樣生動活潑又具有現實意義的話題還有很多，比如第1冊第4單元「Ecation」討論的是父母對孩子的教育方法，以及以熱門人物「Tiger Mother」為例，探討中西方父母對孩子的教育方式的不同；第7單元以美國當紅歌星Lady Gaga的躥紅為線索，探討「Pop Culture」；第8單元「Our Planet」則關注環境保護，並通過日本地震引發的「核泄漏」這個熱門話題，講述作為一個普通人該如何保護我們自己的家園；等等。
另外，本系列教材的《21世紀大學英語應用型視聽說教程（第3版）》的單元主題和《21世紀大學英語應用型綜合教程（修訂版）》的單元主題保持同步，這樣可以使學生從不同的視角和深度討論同一個問題，並通過音頻、視頻和紙質材料不同形式的閱讀和學習，達到提高學生聽、說、讀、寫、譯各方面綜合能力的目的。
2. 提供充分的語言輸入和輸出准備，啟發學生通過儲備知識導入新知識
文本的閱讀和理解是文本與讀者頭腦中的圖式相互作用的復雜過程。由學生已掌握的知識結構導入新的知識時，提供背景和挖掘學習者腦中儲存的知識顯得尤為重要。本系列教材在主題導入和練習設計上都充分體現了這點，使得學習成為一個由舊到新的延續過程。
在每單元的Starter部分，除了通過挖掘學生已有的與本主題相關的詞彙外，還採用了學生最喜歡的視頻形式導入主題。通過觀看視頻和完成相應的練習，學生對接下來要討論的主題已有了充分的准備。在課後練習中需要學生語言輸出時，如Interaction部分，教材不是只羅列要討論的問題，還從學生已有的知識和課文內容出發，有步驟地引導學生集中討論兩三個問題。只有讓學生變得「有話可講」，他們才會願意參與討論。同樣Writing部分，為了使學生不至於感到無從下筆，編者在練習中提供了相關的視頻，以調動學生的積極性，使其導出已有的語言知識儲備，從而順利完成寫作練習。
3. 練習設計強調對文本的理解和語言的實際應用
傳統教材的練習設計過於注重課文詞彙、短語及句型的反復訓練。隨著大學英語改革的深入，大學英語教學者和管理者都意識到，在加強詞彙和句型學習的同時，更應該強調培養學生對文本整體意義的理解；在文本意義的理解中掌握詞彙和句型，而不是孤立地學習。本系列教材中的應用型綜合教程就體現了這個精神。練習設計時，除了Language Focus部分仍舊以詞彙、句型訓練為主外，更重點突出了Text A和Text B中的Comprehension of the Text部分。這部分不再僅僅提供對課文理解的幾個問題，還設計了針對課文段落大意和具體信息的練習，以及對課文重點句子詮釋後回答問題等題型。不僅如此，在其他練習形式中，如Reading in Depth部分，也是學生掌握文意和重點詞彙之後才能完成的練習。而Interaction和Writing部分更是對文本意義理解基礎上的擴展。
為延展學生的語言輸出和語言的實際應用，每單元還增加了一個獨特的環節——Workshop。這部分強調在學完本單元的所有內容後，通過學生間的互動合作學習和學習方式的拓展，完成一個項目型的寫作和總結。
另外，前文中提到的本系列教材力求體現最新《大學英語四／六級考試大綱》的原則和精神，在練習設計中也得到很好的體現。Text A和Text B部分的練習題型充分滿足學生准備四、六級考試的需求。如Text A中的Reading in Depth， Translation；Part C部分的Videobased Writing，以及《21世紀大學英語應用型視聽說教程（第3版）》中按照四、六級考試題型設計的Quiz等都體現了這個編寫原則。
4. 同一個單元的不同模塊體現不同的難易程度，滿足不同層次學生的需求
中國的地區差別和教育多樣化導致即便是同一所學校，甚至同一個班級的學生水平都參差不齊。為解決教學上的不便，本系列教材在一個單元內選取的兩篇課文或視聽材料採取難度遞增的模式。這點在《21世紀大學英語應用型視聽說教程（第3版）》中體現得尤其明顯。在Viewing， Listening and Speaking部分，三段視頻的難易程度逐步遞增。這樣既符合學生學習水平逐步提高的規律，也可供教師針對不同學生選取不同的教學內容。
