    小學(xué)美術(shù)人教版四年級上冊《第9課彩墨世界》教學(xué)設(shè)計(jì)說課稿

    2學(xué)情分析中國傳統(tǒng)繪畫,源遠(yuǎn)流長,扎根于中華民族深厚的文化土壤之中。學(xué)習(xí)中國畫,對繼承和發(fā)揚(yáng)我國民族繪畫,有著非常重要的意義和作用。本課是在學(xué)生以前學(xué)習(xí)中國畫基礎(chǔ)上的進(jìn)一步學(xué)習(xí)。中國畫的門類很多,形式風(fēng)格多樣,彩墨畫就是在水墨畫的基礎(chǔ)上發(fā)展而來的。而彩墨畫特殊的風(fēng)格和表現(xiàn)方法,是兒童藝術(shù)活動充滿趣味的重要部分,用慣了彩筆、蠟筆的學(xué)生們對中國畫有著強(qiáng)烈的興趣。教材中選取了黃永玉先生的《紅荷圖》,畫面中一朵朵荷花色彩奔放,線條樸拙生動,墨色在畫面中自然融合,層次分明。作品中的荷花一改往日中國畫清新淡雅的風(fēng)格,嬌艷欲滴的色彩讓人為之傾倒。此外,教材中精選的朱德群的《無題》、何韻蘭的《綠殤》,也較好地展現(xiàn)了中國畫的筆墨及用色特點(diǎn)。墨的濃淡干濕、墨色的融合交錯、運(yùn)筆的輕重緩急,會產(chǎn)生豐富的畫面效果。另外,教師也可讓學(xué)生通過教科書中的技法圖來進(jìn)一步了解認(rèn)識彩墨畫。

    The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑體部分在句中作表語。2. 句1、2、3中的that在從句中不作成分,只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention,the disease was stopped in its tracks.

Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3.

    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!
