PEP四下Unit 2 Lets spell紅山區(qū)第一小學 張寧教學目標：知識目標：1.學生能夠通過聽例詞發(fā)音，觀察例詞結(jié)構(gòu)中共有的特征，學習字母組合ir、ur在單詞中的發(fā)音規(guī)則；2.能夠跟著錄音說唱歌謠，強化記憶ir、ur的發(fā)音規(guī)則；3.能夠根據(jù)ir、ur的發(fā)音規(guī)則讀出生詞；4.能夠通過完成聽錄音、圈單詞、讀單詞的活動，強化ir、ur的音與形對應(yīng)關(guān)系；5.能夠在單線上完成抄寫句子的活動，做到書寫規(guī)范正確。能力目標:能利用自然拼讀法讀出含有字母組合ir、ur的單詞及韻句。情感目標:能夠積極參與到課堂中，體會自然拼讀法為學習帶來的快樂，增強拼讀英語的自信心。教學重點:字母組合ir、ur的發(fā)音規(guī)律。教學難點:自主拼讀符合發(fā)音規(guī)律的單詞、閱讀含有字母組合ir、ur的單詞。教學過程：Step：Warming up & Revision 熱身活動 溫故知新 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. 設(shè)計意圖：通過TPR復(fù)習已學字母。課堂之初，以“phonics song”開篇，學生們通過動感十足、有節(jié)奏的字母操進行熱身活動。能盡快的投入到課堂中來，并全面系統(tǒng)的復(fù)習了Letter names and Letter sounds.美國心理學家阿爾培根認為，人的信息是有三個部分組成的：55的體語38的聲調(diào)7的言詞。字母操就是根據(jù)26個字母的基本發(fā)音設(shè)計的一種肢體語言。中年級的學生活潑好動，以形象思維為主，字母操從phonics的根本入手，讓學生利用身體的變化協(xié)助字母“形”的記憶。如字母c，做出咳嗽的動作，says:The C says /K/K/K/。又如字母X，做出剪子的手勢，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. 設(shè)計意圖：通過翻翻卡上的單詞，復(fù)習了包括元音字母以及元音字母組合的發(fā)音，目的在于激活學生的已有認知，為后面學生自主拼讀做準備。活動了遵循短時、高效、大密度的原則。4.聽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? 設(shè)計意圖：規(guī)律感知，反復(fù)聽符合發(fā)音規(guī)律的單詞，將教學內(nèi)容在聽和讀中，使學生探究、總結(jié)字母組合“ir”和“ur”的發(fā)音規(guī)律。StepII: Presentation 創(chuàng)設(shè)語境 呈現(xiàn)規(guī)律設(shè)計意圖：由聽本課chant入手，引導(dǎo)學生在“女孩到小鳥家做客”以及“請護士吃漢堡”的整體情境中,充分的感知例詞以及字母組合“ir”和“ur”的發(fā)音。在這個過程中以老師為主，啟發(fā)學生去思考這個規(guī)律。ir組: 1.

T:So I say “ir” you say /:/（音程展示） ir，/:/ ，ir，/:/bird，girl,/:/ Who can spell this word？ 設(shè)計意圖：通過學生自讀例詞，辨別字母組合ir的發(fā)音，通過分音素的方式進行例詞的拆音，讓學生發(fā)音“ir”的發(fā)音規(guī)則3.Drill訓練拼讀 鞏固規(guī)律設(shè)計一個憤怒的小鳥解救客人闖關(guān)的情境。設(shè)計原則：有層次性：首音韻腳、拆分組合、替換加減。 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營救客人。（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? 設(shè)計意圖：通過趣味性的游戲設(shè)計來激發(fā)學生的拼讀熱情。Hurdle 2:Shoot down the pigs.擊落綠豬。（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.最后一擊（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. 設(shè)計意圖：活動由易到難，有層次有針對性，由扶到放，最終達到自主拼讀的目的。由未知向已知過渡，由替換向應(yīng)用過渡。給學生充分自主內(nèi)化的過程。 ur組:1.
