    人教版高中英語(yǔ)必修4Women of achievement說(shuō)課稿4篇

    Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.

After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively.

    人教版新課標(biāo)高中物理必修1時(shí)間和位移說(shuō)課稿2篇

    研究一種物理現(xiàn)象,總是要先從現(xiàn)象的描述入手。機(jī)械運(yùn)動(dòng)作為自然界最簡(jiǎn)單和最基本的運(yùn)動(dòng)形態(tài),它所描述的是物體空間位置隨時(shí)間變化的情況。因此,本節(jié)學(xué)習(xí)描述質(zhì)點(diǎn)做機(jī)械運(yùn)動(dòng)需要時(shí)刻、時(shí)間間隔和位移等概念。相當(dāng)一部分高一學(xué)生在具體過(guò)程中難以區(qū)別時(shí)刻和時(shí)間間隔。另外,由于思維的定式,在第一次接觸既要考慮大小又要考慮方向的問(wèn)題時(shí),會(huì)因不適應(yīng)造成學(xué)習(xí)困難。所以,區(qū)別“路程與位移”“時(shí)刻和時(shí)間間隔”是教學(xué)的重難點(diǎn)所在。學(xué)習(xí)這些內(nèi)容的過(guò)程與方法對(duì)學(xué)習(xí)速度和加速度可以起到奠定基礎(chǔ)的作用。教學(xué)的對(duì)象是高一的學(xué)生,這一時(shí)期的學(xué)生處在好奇善問(wèn)、創(chuàng)新意識(shí)強(qiáng)烈的青少年期。對(duì)于生活中出現(xiàn)的各種現(xiàn)象具有濃厚的興趣。但他們的思維還停留在簡(jiǎn)單的代數(shù)運(yùn)算階段,對(duì)于矢量和矢量運(yùn)算的理性認(rèn)識(shí)幾乎沒(méi)有。且對(duì)生活中出現(xiàn)的時(shí)間、時(shí)刻、時(shí)間間隔等不能做出很好的區(qū)分,對(duì)時(shí)常提及的路程、距離等形成了模糊的前概念。

    人教版新課標(biāo)高中物理必修1自由落體運(yùn)動(dòng)說(shuō)課稿2篇

    學(xué)生回答的方法多樣,讓各小組根據(jù)自己討論出來(lái)的方法對(duì)自己實(shí)驗(yàn)出來(lái)的紙帶進(jìn)行數(shù)據(jù)處理,并求出加速度,并且將多條紙帶都進(jìn)行處理,同時(shí)提醒學(xué)生對(duì)紙帶的選擇。接著,我會(huì)用多媒體展示重物下落實(shí)驗(yàn)打出來(lái)的紙帶,用表格列出一段紙帶上各點(diǎn)的瞬時(shí)速度,準(zhǔn)確畫(huà)出v-t圖像,求出加速度,將結(jié)果給予學(xué)生的結(jié)果作對(duì)比,確定出正確結(jié)論。最后讓學(xué)生分析總結(jié):自由落體運(yùn)動(dòng)是初速度為零的勻加速直線運(yùn)動(dòng),而且,多條紙帶算出來(lái)的加速度的數(shù)值都接近相等,即加速度在實(shí)驗(yàn)誤差允許范圍內(nèi)是相等的。引出重力加速度,介紹概念、方向及大小。(強(qiáng)調(diào)“同一地點(diǎn)”,讓學(xué)生閱讀教材中一些地點(diǎn)的重力加速度,可以了解重力加速度的大小與緯度有關(guān),緯度越大加速度越大)。學(xué)習(xí)了重力加速度后讓學(xué)生根據(jù)之前學(xué)習(xí)的勻變速直線運(yùn)動(dòng)公式推導(dǎo)出自由落體的運(yùn)動(dòng)規(guī)律。設(shè)計(jì)意圖:讓學(xué)生在學(xué)習(xí)過(guò)程中的主體地位和自主觀能動(dòng)性得到充分發(fā)揮,取長(zhǎng)補(bǔ)短,培養(yǎng)了學(xué)生的實(shí)驗(yàn)操作能力,又使學(xué)生對(duì)自由落體運(yùn)動(dòng)的性質(zhì)有深刻的印象,從而解決了本節(jié)課第二個(gè)難點(diǎn)。

    人教版新課標(biāo)高中物理必修1質(zhì)點(diǎn)參考系和坐標(biāo)系說(shuō)課稿2篇

    一、說(shuō)教材《質(zhì)點(diǎn) 參考系和坐標(biāo)系》是人教版普通高中物理必修一第一章第一課的內(nèi)容。本節(jié)課主要介紹了質(zhì)點(diǎn)、參考系、坐標(biāo)系的基本概念。通過(guò)本節(jié)課的學(xué)習(xí)為進(jìn)一步學(xué)習(xí)后續(xù)課程起到了鋪墊的作用。根據(jù)上述教材的結(jié)構(gòu)和內(nèi)容分析,又考慮到高一年級(jí)學(xué)生的認(rèn)知結(jié)構(gòu)及其心理特征,我制定了以下三維教學(xué)目標(biāo):1、知識(shí)與技能:知道質(zhì)點(diǎn)的概念及條件;知道參考系的概念及作用;掌握坐標(biāo)系的簡(jiǎn)單應(yīng)用。2、過(guò)程與方法:促進(jìn)學(xué)生自主學(xué)習(xí),讓學(xué)生積極參與、樂(lè)于探究、勇于實(shí)驗(yàn)、勤于思考,培養(yǎng)學(xué)生的科學(xué)探究能力。3、情感態(tài)度與價(jià)值觀:通過(guò)質(zhì)點(diǎn) 參考系和坐標(biāo)系的學(xué)習(xí),使學(xué)生了解生活與物理的關(guān)系,讓學(xué)生學(xué)會(huì)用科學(xué)的思維去看待事物。根據(jù)普通高中物理課程標(biāo)準(zhǔn),并在吃透教材的基礎(chǔ)上,我確定了以下教學(xué)重點(diǎn)和難點(diǎn):教學(xué)重點(diǎn):質(zhì)點(diǎn)概念的建立。只有掌握了這一點(diǎn)才能更加準(zhǔn)確的理解和掌握后續(xù)教材的相關(guān)內(nèi)容。

    人教版高中語(yǔ)文必修1《別了,“不列顛尼亞”》說(shuō)課稿2篇

    一、說(shuō)教材《別了,不列顛尼亞》是編排在人教版《普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書(shū)語(yǔ)文1(必修)》第四單元的課文,是精讀課文《短新聞兩篇》中的一篇,另一篇是《奧斯維辛沒(méi)有什么新聞》。這一單元的學(xué)習(xí)內(nèi)容是新聞和報(bào)告文學(xué),還有兩篇作品分別是中國(guó)報(bào)告文學(xué)三大里程碑之一的《包身工》和記錄中國(guó)航天事業(yè)輝煌發(fā)展的《飛向太空的航程》。在當(dāng)今信息大爆炸的時(shí)代,如何快速獲得信息,如何在新聞中解讀事件的真相,感悟生活的內(nèi)涵成為語(yǔ)文教學(xué)的又一重大任務(wù)。因此這一單元的編入便更多地具有了時(shí)代意義,體現(xiàn)了語(yǔ)文學(xué)科與日常生活的密切關(guān)系。不僅如此,新聞特寫(xiě)和報(bào)告文學(xué)的選入,拓寬了學(xué)生對(duì)新聞?lì)愇恼碌牧私?,體現(xiàn)語(yǔ)文學(xué)科的工具性作用。在選文的過(guò)程中,新教材同時(shí)注重語(yǔ)文學(xué)科的人文性,四篇作品不僅傳遞著新鮮、真實(shí)的信息,同時(shí)更張顯人文性的厚度,他們以飽滿的情感,縱橫的歷史經(jīng)驗(yàn)。
