PEP四下Unit 2 Lets spell红山区第一小学 张宁教学目标：知识目标：1.学生能够通过听例词发音，观察例词结构中共有的特征，学习字母组合ir、ur在单词中的发音规则；2.能够跟着录音说唱歌谣，强化记忆ir、ur的发音规则；3.能够根据ir、ur的发音规则读出生词；4.能够通过完成听录音、圈单词、读单词的活动，强化ir、ur的音与形对应关系；5.能够在单线上完成抄写句子的活动，做到书写规范正确。能力目标:能利用自然拼读法读出含有字母组合ir、ur的单词及韵句。情感目标:能够积极参与到课堂中，体会自然拼读法为学习带来的快乐，增强拼读英语的自信心。教学重点:字母组合ir、ur的发音规律。教学难点:自主拼读符合发音规律的单词、阅读含有字母组合ir、ur的单词。教学过程：Step：Warming up & Revision 热身活动 温故知新 1. Greeting. 2. Lets sing a song.字母操 T:At first,lets sing a song,please sing and do the actions with your smiles. 设计意图：通过TPR复习已学字母。课堂之初，以“phonics song”开篇，学生们通过动感十足、有节奏的字母操进行热身活动。能尽快的投入到课堂中来，并全面系统的复习了Letter names and Letter sounds.美国心理学家阿尔培根认为，人的信息是有三个部分组成的：55的体语38的声调7的言词。字母操就是根据26个字母的基本发音设计的一种肢体语言。中年级的学生活泼好动，以形象思维为主，字母操从phonics的根本入手，让学生利用身体的变化协助字母“形”的记忆。如字母c，做出咳嗽的动作，says:The C says /K/K/K/。又如字母X，做出剪子的手势，says:The X says /KS/KS/KS/ 3. Lets review.翻翻卡 T：Now，lets review somes words together.Show me your fingers，lets spell it. 设计意图：通过翻翻卡上的单词，复习了包括元音字母以及元音字母组合的发音，目的在于激活学生的已有认知，为后面学生自主拼读做准备。活动了遵循短时、高效、大密度的原则。4.听chant. T:Now，I want to share a chant with you，listen carefully，Which pronounciation appeared most？ Students speak out the pronounciation /:/. T:Can you tell me which word contains /:/ in this chant? 设计意图：规律感知，反复听符合发音规律的单词，将教学内容在听和读中，使学生探究、总结字母组合“ir”和“ur”的发音规律。StepII: Presentation 创设语境 呈现规律设计意图：由听本课chant入手，引导学生在“女孩到小鸟家做客”以及“请护士吃汉堡”的整体情境中,充分的感知例词以及字母组合“ir”和“ur”的发音。在这个过程中以老师为主，启发学生去思考这个规律。ir组: 1.

T:So I say “ir” you say /:/（音程展示） ir，/:/ ，ir，/:/bird，girl,/:/ Who can spell this word？ 设计意图：通过学生自读例词，辨别字母组合ir的发音，通过分音素的方式进行例词的拆音，让学生发音“ir”的发音规则3.Drill训练拼读 巩固规律设计一个愤怒的小鸟解救客人闯关的情境。设计原则：有层次性：首音韵脚、拆分组合、替换加减。 T:Boys and girls,you know we still have another guest,but the green pig hide her,can you help the bird find our guest?There are three hurdles,are you ready?Hurdle 1 Rescue the guest营救客人。（words） T:Now,spell the words as quickly as you can,after that I will ask some of you to shoot down the green pigs.OK? 设计意图：通过趣味性的游戏设计来激发学生的拼读热情。Hurdle 2:Shoot down the pigs.击落绿猪。（sentences） T:Read the sentences as quickly as you can,after that I will ask some of you to read it.Hurdle 3:Final blow.最后一击（Make new words） T：You are good shooter，lets give the green pigs the final below.Take out your letter cards,try to make some new word just like me. 设计意图：活动由易到难，有层次有针对性，由扶到放，最终达到自主拼读的目的。由未知向已知过渡，由替换向应用过渡。给学生充分自主内化的过程。 ur组:1.
