新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學(xué)設(shè)計
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

(1) 求從正方形ABCD 開始，連續(xù)10個正方形的面積之和；(2) 如果這個作圖過程可以一直繼續(xù)下去，那么所有這些正方形的面積之和將趨近于多少？分析：可以利用數(shù)列表示各正方形的面積，根據(jù)條件可知，這是一個等比數(shù)列。解：設(shè)正方形的面積為a_1，后續(xù)各正方形的面積依次為a_2, a_(3, ) 〖…,a〗_n,…，則a_1=25,由于第k+1個正方形的頂點分別是第k個正方形各邊的中點，所以a_(k+1)=〖1/2 a〗_k,因此{a_n}，是以25為首項，1/2為公比的等比數(shù)列.設(shè){a_n}的前項和為S_n（1）S_10=(25×[1-(1/2)^10 ] )/("1 " -1/2)=50×[1-(1/2)^10 ]=25575/512所以，前10個正方形的面積之和為25575/512cm^2.(2)當(dāng)無限增大時，無限趨近于所有正方形的面積和

今天我說課的內(nèi)容是人教版高中物理必修1第四章第四節(jié)《力學(xué)單位制》，我的說課內(nèi)容將按下列程序展開。首先是本節(jié)教材的分析。一、說教材1、本節(jié)課在教材中的地位單位是學(xué)生在高考中最容易犯錯的地方之一，本節(jié)課內(nèi)容貫穿整個物理學(xué)科的每部分。學(xué)好這部分內(nèi)容對所有的自然學(xué)科都有幫助。2、教材簡析教材可分為：單位制等概念的來源和單位制的推廣。二、說教學(xué)目標(biāo)：教學(xué)目標(biāo)的設(shè)定是教師進行課堂授課的一個重要依據(jù)，是教師完成教學(xué)任務(wù)的鑒定標(biāo)準(zhǔn)。根據(jù)新課標(biāo)要求和學(xué)生特點我對本節(jié)制定以下教學(xué)目標(biāo)（1）了解什么是單位制，知道國際單位制中力學(xué)的三個基本單位。（2）認識單位制在物理學(xué)中和國際交往中的重要作用。（3）學(xué)會用單位運算來檢查物理公式推導(dǎo)的正確性，從而培養(yǎng)學(xué)生解決實際問題的能力。
人教A版高中數(shù)學(xué)必修一對數(shù)的運算教學(xué)設(shè)計（2）
學(xué)生已經(jīng)學(xué)習(xí)了指數(shù)運算性質(zhì)，有了這些知識作儲備，教科書通過利用指數(shù)運算性質(zhì)，推導(dǎo)對數(shù)的運算性質(zhì)，再學(xué)習(xí)利用對數(shù)的運算性質(zhì)化簡求值。課程目標(biāo)1、通過具體實例引入，推導(dǎo)對數(shù)的運算性質(zhì)；2、熟練掌握對數(shù)的運算性質(zhì)，學(xué)會化簡，計算.數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：對數(shù)的運算性質(zhì)；2.邏輯推理：換底公式的推導(dǎo)；3.數(shù)學(xué)運算：對數(shù)運算性質(zhì)的應(yīng)用；4.數(shù)學(xué)建模：在熟悉的實際情景中，模仿學(xué)過的數(shù)學(xué)建模過程解決問題.重點：對數(shù)的運算性質(zhì)，換底公式，對數(shù)恒等式及其應(yīng)用；難點：正確使用對數(shù)的運算性質(zhì)和換底公式．教學(xué)方法：以學(xué)生為主體，采用誘思探究式教學(xué)，精講多練。教學(xué)工具：多媒體。一、 情景導(dǎo)入回顧指數(shù)性質(zhì)：(1)aras＝ar＋s(a＞0，r，s∈Q)．(2)(ar)s＝ (a＞0，r，s∈Q)．(3)(ab)r＝ (a＞0，b＞0，r∈Q)．那么對數(shù)有哪些性質(zhì)？如 要求：讓學(xué)生自由發(fā)言，教師不做判斷。而是引導(dǎo)學(xué)生進一步觀察.研探.
人教A版高中數(shù)學(xué)必修一誘導(dǎo)公式教學(xué)設(shè)計（2）
本節(jié)主要內(nèi)容是三角函數(shù)的誘導(dǎo)公式中的公式二至公式六，其推導(dǎo)過程中涉及到對稱變換，充分體現(xiàn)對稱變換思想在數(shù)學(xué)中的應(yīng)用，在練習(xí)中加以應(yīng)用，讓學(xué)生進一步體會 的任意性；綜合六組誘導(dǎo)公式總結(jié)出記憶誘導(dǎo)公式的口訣：“奇變偶不變，符號看象限”，了解從特殊到一般的數(shù)學(xué)思想的探究過程，培養(yǎng)學(xué)生用聯(lián)系、變化的辯證唯物主義觀點去分析問題的能力。誘導(dǎo)公式在三角函數(shù)化簡、求值中具有非常重要的工具作用，要求學(xué)生能熟練的掌握和應(yīng)用。課程目標(biāo)1.借助單位圓，推導(dǎo)出正弦、余弦第二、三、四、五、六組的誘導(dǎo)公式，能正確運用誘導(dǎo)公式將任意角的三角函數(shù)化為銳角的三角函數(shù)，并解決有關(guān)三角函數(shù)求值、化簡和恒等式證明問題2.通過公式的應(yīng)用，了解未知到已知、復(fù)雜到簡單的轉(zhuǎn)化過程，培養(yǎng)學(xué)生的化歸思想，以及信息加工能力、運算推理能力、分析問題和解決問題的能力。
