一、 教材分析民主管理這個知識點雖然沒有理論難度容易理解，但它具有較強的實用價值，可以幫學(xué)生找到一種切實可行的政治參與路徑。因為村委會的知識對城市中的孩子來說比較陌生，所以本課側(cè)重于講解居委會的內(nèi)容。二、教學(xué)目標(biāo)（一）知識目標(biāo)1、識記村委會、居委會及其作用2、正確理解基層民主管理中公民民主參與的形式3、聯(lián)系實際分析公民在基層管理組織中的作用（二）能力目標(biāo)提高公民參與民主管理的能力（三）情感、態(tài)度與價值觀目標(biāo)通過學(xué)習(xí)體驗參與民主管理的意義和價值三、教學(xué)重點難點重點：村委會、居委會及其作用，公民在基層管理組織中的參與的形式和作用難點：公民在基層管理組織中的參與的形式和作用四、學(xué)情分析高一學(xué)生的優(yōu)點是：第一，對什么都好奇，具有強烈的求知欲；第二，可塑性強，適當(dāng)引導(dǎo)有利于培養(yǎng)其樹立正確的世界觀、人生觀和價值觀；第三，孩子們性格活潑,、樂于實踐、容易激活。
人教版高中政治必修2民主監(jiān)督：守望公共家園教案
一、教材分析《民主監(jiān)督：守望公共家園》是高一政治必修2第一單元第二課第四框題。在此之前，學(xué)生們已經(jīng)學(xué)習(xí)了公民所享有的政治權(quán)利和自由，了解到公民享有監(jiān)督權(quán)，這為過渡到本框題的學(xué)習(xí)起到了鋪墊的作用。本框題承接了教材第一課“公民的政治權(quán)利和自由”這部分內(nèi)容，又為后面第四課“權(quán)力的行使：需要監(jiān)督”的學(xué)習(xí)埋下伏筆。所以學(xué)好這個框題為學(xué)好以后的政治常識打下牢固的基礎(chǔ)，而且它在整個教材中也起到了承上啟下的作用。二、教學(xué)目標(biāo)（一）知識目標(biāo)1、識記公民的民主監(jiān)督權(quán)利、作用2、理解公民的民主監(jiān)督的重要性。3、學(xué)會分析如何行使監(jiān)督權(quán)（二）能力目標(biāo)通過學(xué)習(xí)逐步形成民主監(jiān)督能力。（三）情感、態(tài)度與價值觀目標(biāo)通過學(xué)習(xí)培養(yǎng)學(xué)生主人翁責(zé)任感。三、教學(xué)重點難點重點：公民的民主監(jiān)督權(quán)利、作用、重要性。難點：民主監(jiān)督的重要性

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!
