单元音-英语发音精讲教学设计

课程名称 单元音教学设计 教材分析 本节课选自英语语音板块 —— 单元音部分。语音是英语学习的基础，12 个单元音（5 个长元音 /iː//ɑː//ɔː//ɜː//uː/；7 个短元音 /ɪ//e//æ//ʌ//ɒ//ʊ//ə/）是单词拼读、听力辨别的核心。本节课聚焦单元音，结合口型要领、字母及字母组合开展教学，帮助学生区分长、短元音，建立 “音形对应” 意识，改变死记硬背单词的习惯，落实中职英语培养学生语言运用能力的教学目标，同时为后续双元音、辅音的学习打好基础。 学情分析 授课对象为中职一年级学生。学生英语基础参差不齐，初中音标基础普遍薄弱，容易混淆长元音与短元音；可以认读简单单词，但缺少借助音标拼读单词的习惯，多依靠机械记忆背诵单词。学生乐于模仿发音，愿意参与小组互动任务，但课堂注意力持续时间有限，口型相近的单元音极易混淆。因此课堂要强化教师示范、跟读模仿、对比操练，设置游戏、双人合作降低学习难度，调动学生课堂参与积极性。 教学目标 After learning this lesson，students can 通过本课的学习，学生能够 Knowledge Objectives 知识目标 Master 12 monophthongs；grasp the differences between long vowels and short vowels；recognize corresponding letters and lettercombinations. 掌握 12 个单元音，分清长元音、短元音的区别；识别单元音对应的字母及字母组合。 Ability Objectives 能力目标 Be able to tell long vowels from short vowels by listening；read words containing monophthongs with correct mouth shape and sound length. 能够听辨区分长短单元音；使用正确口型、把握音长朗读含有单元音的单词。 Emotional Objectives 情感目标 Build confidence in English pronunciation；develop the habit of using phonetic symbols to memorize new words. 建立英语发音自信心，养成借助音标记忆单词的学习习惯。 教学重难点 Key Points 重点 Master 12 monophthongs；master the corresponding letters and letter combinations. 掌握 12 个单元音；掌握单元音对应的典型字母、字母组合。 Difficult Points 难点 Distinguish long vowels and short vowels；master correct mouth shape and sound‑length control. 区分长元音与短元音；掌握正确口型，控制发音音长。 教学方法 · TaskBased Language Teaching 任务型教学法：设置辨音、对比朗读、双人互查等任务开展练习。 · Situational Teaching Method 情境教学法：结合单词、短句、谚语创设发音操练情境。 · Audiolingual Method 听说法：教师示范口型，学生大量模仿跟读，及时纠正口型与音长错误。 课前准备 教师：熟练掌握 12 个单元音口型要点；准备 PPT 课件、音标挂图、单词练习清单、简单绕口令素材。 学生：预习音标表；准备笔记本，预习课本语音板块。 教学媒体 Phonetic chart, PPT, word list, blackboard 音标挂图、PPT 课件、单词表、黑板 教学过程 教学环节 教师活动设计 学生活动设计 设计意图 Warming‑up & Lead‑in 热身导入（7 mins） Step1 Warming‑up & Lead‑in 热身导入（7 mins） 1.Greet students. Put forward guiding question: Many students pronounce “sheep” and “ship” in the same way. Why? 师生问好，抛出引导问题：很多同学把 sheep 和 ship 读成一样，是什么原因？引出长短单元音的区别。 2.Show phonetic chart on PPT and wall chart. Present 12 monophthongs, divide them into 5 long vowels and 7 short vowels. Explain the concept: monophthong means the mouth shape keeps unchanged while pronouncing. PPT 和音标挂图展示 12 个单元音，分为长元音、短元音；讲解概念：单元音发音过程口型保持不变。 Observe phonetic chart, listen carefully and take key notes. Think over the guiding question. 观察音标挂图，认真听讲，记录笔记，思考导入问题。 利用易混淆单词创设问题情境，引出单元音主题，帮助学生建立 12 个单元音整体认知框架，激发学生求知兴趣。 Presentation 新知讲授（22 mins） Step2 Presentation 新知讲授（22 mins） Part 1 Long vowels 5 个长元音：/iː//ɑː//ɔː//ɜː//uː/ Demonstrate mouthshape one by one, remind students to prolong the sound. Explain corresponding letters /letter combinations, lead students to read words and short sentences. 逐个示范口型，提示长元音发音要拉长；讲解对应字母、字母组合，带读例词和短句。 1./iː/long vowel：smile, draw out sound；letters e, ee, ea；words sheep, meat；Sentence: She sees the green tree. 长元音 /iː/：微笑，拉长音；字母 e,ee,ea；例词 sheep, meat；句子：She sees the green tree. 2. 2./ɑː/long vowel：open mouth wide；letters a, ar；words car, grass；Sentence: So far, so good. 长元音 /ɑː/：张大嘴巴；字母 a,ar；例词 car, grass；句子：So far, so good. 3./ɔː/long vowel：round lips；letters or, al, oor；words horse, tall. 长元音 /ɔː/：圆唇；字母 or,al,oor；例词 horse, tall. 4./ɜː/long vowel：relax lips；letters er, ir, ur, or；words bird, nurse；Sentence: The early bird catches the worm. 长元音 /ɜː/：嘴唇放松；字母 er,ir,ur,or；例词 bird, nurse；谚语：The early bird catches the worm. 5./uː/long vowel：round and tight lips；letters oo, o, u；words moon, ruler. 长元音 /uː/：双唇收圆收小；字母 oo,o,u；例词 moon, ruler. Part2 Short vowels 7 个短元音：/ɪ//e//æ//ʌ//ɒ//ʊ//ə/ Remind students short vowels should be read short and quick. Explain letters & letter combinations with example words. 提示短元音发音短促有力，讲解字母组合和例词。 1./ɪ/short vowel：quick sound；letters i, y, e；words ship, happy；Sentence: Where there is a will, there is a way. 短元音 /ɪ/：短促；字母 i,y,e；例词 ship, happy；谚语：Where there is a will, there is a way. 2./e/short vowel：halfopen mouth；letters e, ea；words egg, bread. 短元音 /e/：半开口；字母 e,ea；例词 egg, bread. 3./æ/short vowel：open mouth fully；letter a；words cat, bag. 短元音 /æ/：牙床全开；字母 a；例词 cat, bag. 4./ʌ/short vowel：flat lips；letters u, o；words bus, lucky. 短元音 /ʌ/：双唇平放；字母 u,o；例词 bus, lucky. 5./ɒ/short vowel：round open lips；letters o, a；words dog, hot. 短元音 /ɒ/；圆唇开口；字母 o,a；例词 dog, hot. 6./ʊ/short vowel：small round lips；letters oo, o；words book, woman. 短元音 /ʊ/；小圆唇；字母 oo,o；例词 book, woman. 7./ə/short weak vowel：relaxed mouth；letters er, or, a；words teacher, doctor. 短弱元音 /ə/；口型放松；字母 er,or,a；例词 teacher, doctor. 💡Important Tip：Monophthong keeps the same mouth shape all the time. Long vowels are longer, short vowels are short and powerful. 提示：单元音发音全程口型不变；长元音拉长读，短元音短促有力。 Teacher walks around the classroom, observes students’ lip movement and correct wrong pronunciation timely. 教师巡视课堂，观察学生口型，及时纠正错误发音。 Imitate pronunciation following teacher；read example words group by group；put hands on throat to feel vocal‑cord vibration；take notes for key letter combinations. 跟随教师模仿发音，分组朗读例词；手放在喉咙感受声带振动；笔记本记录重点字母组合 由长元音到短元音循序渐进，教师口型示范降低音标抽象感；通过例词、短句巩固音形对应；体感感受帮助学生记忆发音要点，突破本课难点。 Consolidation Practice 综合操练（12 mins） Step3 Consolidation Practice 综合操练 1.Contrast reading 对比朗读：Read groups of long‑short vowel pairs：/iː/‑/ɪ/；/uː/‑/ʊ/；/ɔː/‑/ɒ/。Remind students to tell sound length difference. 开展长短元音对读练习，如 /iː/‑/ɪ/；/uː/‑/ʊ/；/ɔː/‑/ɒ/，提醒学生区分音长。 2.Example word groups: sheep‑ship；moon‑book；horse‑dog。 Phoneme discrimination game 辨音小游戏：Teacher reads words, students tell which monophthong the word contains. 教师读单词，学生抢答单词包含哪一个单元音。例词：cat, bird, book, car。 3.Tongue‑twister practice 绕口令练习：She sells seashells on the seashore. Teacher reads first. Students can read slowly if they are weak in pronunciation. 教师领读；基础薄弱学生可以慢速朗读。 4.Pair‑work 双人合作任务：Students take turns to read phonemes and example words to each other. Teacher walks around to give guidance and correct mistakes. 两人一组，互相朗读单元音和例词；教师巡堂，个别纠错指导。 Conclusion 课堂总结（3 mins） Summary 课堂总结 1.Review 12 monophthongs together with students: 5 long vowels and 7 short vowels. 和学生一起回顾 12 个单元音：5 长 7 短。 2.Emphasize two key points：①Mouth shape remains unchanged for monophthongs；②Distinguish long vowels and short vowels by sound length. 强调两个核心要点：①单元音口型全程不变；②依靠音长区分长元音、短元音。 3.Encourage students to use phonetic symbols when learning new words. 鼓励学生学习新单词主动使用音标。 Homework ① Read 12 monophthongs and example words 3 times. Record your reading if possible. 朗读 12 个单元音及对应例词 3 遍，有条件录制朗读音频。 ② Practice the tongue‑twister until you can read it fluently. 练习课堂绕口令，做到流利朗读。 ③ Try to use phonetic symbols to read 5 new words from textbook, mark their monophthongs. 借助音标拼读课本 5 个生词，标注单词里面的单元音。 Blackboard Design Monophthongs（单元音） 12 Monophthongs ▷Long vowels（5）： /iː/ /ɑː/ /ɔː/ /ɜː/ /uː/ ▷Short vowels（7）： /ɪ/ /e/ /æ/ /ʌ/ /ɒ/ /ʊ/ /ə/ ✅Key tips： 1.Mouth shape stays unchanged. 2.Long vowels → prolong；Short vowels → short & quick. Teaching Evaluation 过程性评价：课堂观察学生口型模仿、跟读、双人互动参与情况；对敢于开口、发音进步的学生口头表扬；当场纠正发音、口型错误。 任务评价：观察学生对比朗读、辨音抢答、绕口令、双人互读的完成情况，判断学生是否可以区分长、短单元音，把握口型与音长。 课后评价：检查课后朗读、拼读单词作业，了解学生单元音掌握情况，作为后续语音教学参考。 Teaching Reflections Most students can recognize 12 monophthongs and finish imitative reading in class. But some students still cannot tell long vowels from short vowels clearly；individual differences are obvious among students. 大部分学生课堂能够识别 12 个单元音，可以完成模仿朗读。但部分学生依旧无法清晰区分长短元音，学生个体差异明显。 In future teaching, more contrast practice should be arranged. Design simpler tasks for students with weak foundation. Offer more chances for students to speak in class. Combine phonemes with more daily‑used words to consolidate their mastery of monophthongs. 后续教学中，需要增加更多长短元音对比练习；为基础薄弱学生设计难度更低的任务；多给学生开口机会；将单元音和更多常用单词结合，巩固单元音掌握程度。 精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
