人教版高中英語必修2Wildlife Protection說課稿3篇
When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now. It’s about Jack Chen’s（成龍）and Yang Ziqiong’s wildlife protection.Step4. Listening (twice 13 minutes)This time, I’ll ask the Ss to fill in the blanks of the monologue of the 2 movie stars above. Step5.Discussion (3 minutes)Which would you like to choose to wear, clothes made of cotton, artificial leather or animal skins? Why ?Step6. Summary (3 minutes)1. If there were no wildlife, there wouldn’t exist human beings. If the buying stops, the killing can, too.2. Animals are our friends. To love animals is to love ourselves. Stop hunting, killing and destroying wildlife.3. Let’s live in harmony with all the living things in the world. Step7.

Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. 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. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.

人教版高中政治必修4矛盾是事物發(fā)展的源泉和動(dòng)力說課稿（二）
一、說教材1、本框的地位和作用本框題是人教版普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書思想政治必修4《生活與哲學(xué)》第三單元第九課第一個(gè)框題。從這一框開始學(xué)生學(xué)習(xí)唯物辯證法中最基本的概念——矛盾。世界是普遍聯(lián)系和變化發(fā)展的，聯(lián)系的根本內(nèi)容是矛盾，發(fā)展的根本動(dòng)力也是矛盾。矛盾的觀點(diǎn)是唯物辯證法的根本觀點(diǎn)。矛盾規(guī)律即對(duì)立統(tǒng)一規(guī)律揭示了事物發(fā)展的源泉和動(dòng)力。矛盾分析法是我們認(rèn)識(shí)世界和改造世界的根本方法。因而本框題起著承上啟下的作用。2、教學(xué)目標(biāo)知識(shí)與技能：識(shí)記：矛盾、矛盾同一性、斗爭(zhēng)性的含義；矛盾普遍性、特殊性的含義。理解：矛盾同一性與斗爭(zhēng)性的辯證關(guān)系；矛盾普遍性和特殊性的辯證關(guān)系及其重要意義。運(yùn)用：聯(lián)系實(shí)例，分析矛盾含義和矛盾普遍性含義；聯(lián)系生活實(shí)例，分析矛盾特殊性含義。
人教版高中政治必修4矛盾是事物發(fā)展的源泉和動(dòng)力說課稿（一）
《矛盾是事物發(fā)展的源泉和動(dòng)力》是人教版普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書，《思想政治》必修第4冊(cè)，《生活與哲學(xué)》第3單元第9課的第1框的內(nèi)容。本節(jié)課的這部分內(nèi)容，是在學(xué)生們學(xué)習(xí)了上一框用發(fā)展練習(xí)的觀點(diǎn)看問題的基礎(chǔ)上展開的，本框通過矛盾同一性和斗爭(zhēng)性，普遍性與特殊性這兩大關(guān)系，揭示矛盾是事物發(fā)展的源泉和動(dòng)力。矛盾是本書的一個(gè)重要觀點(diǎn)。對(duì)于學(xué)生樹立正確的人生觀以及下一階段的學(xué)習(xí)都用很重要的作用。二、說教學(xué)目標(biāo)（每個(gè)說1~2個(gè)）按照新課標(biāo)教學(xué)目標(biāo)，結(jié)合著高二年級(jí)學(xué)生他們的認(rèn)知結(jié)構(gòu)及其心理特征，我制定了以下的教學(xué)目標(biāo)：1、知識(shí)目標(biāo)：通過學(xué)習(xí)掌握矛盾的含義。矛盾的同一性和斗爭(zhēng)性。矛盾的普遍性和特殊性。2、過程與方法的目標(biāo)：使學(xué)生初步形成用矛盾的統(tǒng)一性和斗爭(zhēng)性相統(tǒng)一的觀點(diǎn)認(rèn)識(shí)和把握事物的能力，以及通過運(yùn)用矛盾普遍性和特殊性辯證關(guān)系的原理認(rèn)識(shí)和解決問題的能力。
人教版高中歷史必修1羅馬法的起源與發(fā)展說課稿
學(xué)生思考回答后歸納：隨著征服地區(qū)的擴(kuò)大，出現(xiàn)了許多新問題，新矛盾，原有的公民法已經(jīng)無法適應(yīng)這些新變化（質(zhì)疑）。公民法適用范圍限于羅馬公民，用來調(diào)整他們之間的關(guān)系，羅馬公民受到法律保護(hù)，并享受法律賦予的權(quán)利。在擴(kuò)張中納入到疆域中的許多外邦人不能受到法律的保護(hù)，在這種背景下，公民法發(fā)展成萬民法。萬民法的出現(xiàn)，一方面由于公民法的狹隘性，另一方面伴隨對(duì)外戰(zhàn)爭(zhēng)的勝利，奴隸制在羅馬得到快速發(fā)展。為了更加有效地保護(hù)奴隸主的私人利益，迫切需要建立和完善法律制度來維護(hù)統(tǒng)治階級(jí)的利益不受侵犯。問題探究：萬民法的制定產(chǎn)生哪些作用？學(xué)生思考回答后總結(jié)：萬民法取代公民法，協(xié)調(diào)了羅馬人和外邦人之間的關(guān)系及外邦人相互之間的關(guān)系，對(duì)于在龐大帝國內(nèi)微細(xì)，協(xié)調(diào)各地區(qū)的民族關(guān)系、社會(huì)矛盾也祈禱重要作用。萬民法使法律具有了更大的適用范圍，也成為鞏固羅馬統(tǒng)治的重要工具。
