我也是农村长大的孩子,在农村的日子就是我整个童年,虽然没有城市的繁荣和物质基础,但在农村我就是一只自由自在、欢乐无比的小鸟。走进白石小学,我仿佛又回到了我那个自由洒脱的童年。孩子们的欢声笑语,孩子们的调皮捣蛋,还有孩子们的聪明伶俐,无不让我感到开心和幸福。这种幸福感不像是亲人朋友给予的爱,而是把你带进你无法回到的过去的难忘时光。在我们安排的课程中,里面大多数是以第二课堂为主。为了吸引孩子们的注意和培养他们的兴趣,我们也是使出浑身解数,让课程变得有趣而不乏味。虽然经历了当老师的辛苦,但孩子们带给我们的欢乐和感动让我们觉得一切都值得。在我所参与的课堂中,我看到了“老师们”的窘迫,但孩子们却还是学得很认真笑得很开心。这就是我们现在无法相比的,孩子们的天真热情,单纯可爱,让我们这些最初不抱好想法的大学生感到温暖,很快,我们就融入其中了。
在我们教授孩子们知识的同时,也受到孩子们很多的启发。比如说,在课堂上我按照自己的备课套路跟孩子们讲课,孩子们有的时候并没有听进去。确切地说是没有听懂。作为一位准教师,我没有按照实际情况去衡量,不仅没有预想的效果,反而造成孩子厌学的情绪。经过多次授课,我们在孩子们身上反馈的信息比我们教给孩子们的还要丰富。所以有时我都觉得,其实三下乡最大的作用是教会我们这些大学生如何成长为一个合格的老师的。还有在孩子们身上学到的乐观、坚强,都是我遗失了很久的宝贝。
提问:结合课本找出城市地域结构模式的类型及各自特点,模式形成的因素又有哪些?学生回答,使其掌握基本模式及特点,通过对比,分析把握每一模式各自的特征,学会把握事物本质。◆设计意图:阅读课本,总结归纳,同时引导,通过原因规律的探究,大胆设想,总结规律掌握人文地理学习思路。4.活动设计:内部空间结构变化,结合实例,分析说明。提问:结合江宁区的变化,分析江宁区城市结构发生了哪些变化?结合课本24页活动题,提出功能结构布局方案?通过理论联系实际,让学生更好理解理论,掌握城市结构布局的变化及其影响因素,通过活动题方案的提出,学生能够掌握布局的规律性,解决问题。设计意图:理论联系实际,知识的不枯燥性,提高学生学习兴趣。同时,能够通过总结,深层次认识城市结构布局,活学活用。
四.设计反思我在设计本课时,希望通过情境的创设充分再现历史,并利用多媒体辅助教学,破重点、化难点,让学生主动参与到学习过程中,从而突破狭小的教室空间,让学生真正做到感知历史,立足现实,展望未来。自主,交流、合作、探究是课程改革中着力倡导的新型学习方式。课堂教学中如何开展小组合作的探究学习存在着很多困难,首先是课堂教学时间有限,如何体现面向全体,给每个学生以机会?再次,历史问题的讨论只能依托于史料才能使讨论不沦为空谈,课堂上通过网络提供大量的史料(文字、图片或其他),势必不能有充分时间让学生阅读分析。如何解决这些问题呢?措施一:要形成较固定的历史学习合作小组。选定一位同学担任组长,负责协调措施二:要设置有利于学生探究的问题情境措施三:要把课堂教学与课外学习结合起来。在课前就印发相关的材料,或引导学生去查阅相关的资料,让学生有个充分的阅读、思考、交流的时间,是保证课堂上小组交流能成功实现的一个前提
老师们,同学们,大家上午好!今天我国旗下讲话的主题是:学“八礼四仪”,让文明传承。全国都在开展文明礼仪养成教育,强调要突出抓好未成年人的“八礼四仪”,具体包括仪表之礼、餐饮之礼、言谈之礼、待人之礼、行走之礼、观赏之礼、游览之礼、仪式之礼这八个方面的礼仪教育。四仪是指7岁入学仪式;10岁成长仪式;14岁青春仪式;18岁成人仪式。这套“八礼四仪”融入了“爱、善、诚、勤、俭、美”六种理念和价值取向,注重从生活细节入手,未成年人易懂易学易做。“八礼四仪”是传承文明的需要。古老的中华民族自古以来就享有“礼仪之邦”的美称。在五千年悠久的历史长河中,不但创造了灿烂的文化,而且形成了古老民族的传统美德,很多优良的、传统的礼仪规范,直至今天仍然有很强大的生命力,它是中华民族的宝贵的精神财富。
Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.
The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration. Multi-media, textbook, notebooks.Step 1: Warming up and predictionLook at the title and the pictures of the text and predict what the text will be about?2. What are the main reasons for space exploration?
⑦在我看来, 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.

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

二、学生情况分析(说学法)1、学生学习基础分析:学生通过对《生活与哲学》前面三个单元的学习,初步掌握了运用唯物论、辩证法、认识论的观点去认识问题、分析问题的能力;再通过对第十一课的学习,学生对马克思主义的历史观有了初步的理解,初步树立了正确的理想信念,这为本课教学目标的落实奠定了知识基础。 2、学生能力分析 :高二学生拥有一定生活体验,具备一定的信息收集和筛选能力、阅读能力、语言表达能力、对问题的一定的探究能力,同伴合作能力和具备初步逻辑思维能力。3、学生心理分析:在我国现阶段,以为人民服务为核心的社会主义道德建设过程中涌现了大批的先进人物和道德典范,但同时由于社会价值的多元化,个人主义、享乐主义、拜金主义等资本主义腐朽思想也同样在影响着当代的中学生。
1、思维保守僵化,缺乏忧患意识。受一些家庭及社会舆论的影响,部分青年员工思想观念较为落后、思维方式较为保守,认为进入了事业单位就有了终身保障,干与不干一个样,干好干坏一个样,只要不犯原则性的错误就不会使自己丢掉“饭碗”,对工作和生活缺乏必要的责任心和紧迫感,进而产生麻痹懈怠、疲沓涣散的情绪,对单位发展和个人成长造成长期不良影响。比较典型的有两种表现,一是盲目乐观,认为在费收工作“简单、机械”,并不用付诸努力去刻苦钻研,对新业务、新知识、新技能不学习、不补充、不提高;二是消极冷漠,认为费收工作“单调、枯燥”,对工作没有激情,总是提不起干劲,处事马虎,应付交差,缺乏有为意识和竞争意识,把个人置身于集体之外,对单位的发展漠不关心。
“创意无限,匠心支撑”。当下,创新创业大潮涌动,“互联网+”颇受青睐,大批创客投身其中。这里头有脚踏实地的深耕者,但也有不少一天到晚想着如何造噱头、拉投资,幻想借互联网的东风,“抄一把就走”之人。与此相应,很多产品往往火了一把便再无踪迹。如此“创”法,除了搅出些过时即破的泡沫,难言价值。创新创业不应成为浮躁的代名词,那些真正成功的互联网神话缔造者,远非鼓吹概念、贩卖情怀这么简单。很多大佬正是以其对细节近乎严苛的追求向大家证明,只有“互联网+工匠精神”,才能出优质产品。
二万五千里长征,一次改变中国人命运的征程已在人们的评说中去过了大半个世纪。照现代社会这种急速更新换代的观念,早已是好几个时代过去了。按我们熟悉的某种号召“过去的就让它过去吧”。再说下去,就成了枭鸣似的烦扰,不免令人生厌。然而长征却不同。人们总在不断的言说、探究、拷问。我想或许是由于长征所代表的一种精神吧――一种全人类永恒追求的精神――坚持到底。 “红军不怕远征难”的精神!正因为这心中永存的信念,红军才有了“万水千山只等闲,五岭逶迤腾细浪,乌蒙磅礴走泥丸”的英雄气概!正因为这心中永存的信念,才有了“亲人送水来解渴,军民鱼水一家人”的温情!
