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.

Knowledge objectives:(1) to make Ss grasp the usage of words, expressions and sentence structures: statistics, struggle, thanks to, rid of, some patterns for persuasion, the “ing” form as subject and object;(2)to use learnt knowledge to persuade sb.Ability objectives:(1) to develop Ss’ reading skills(skimming, scanning, word guessing);(2) to improve Ss’ speaking, communicating and cooperating skills.Emotional objectives:to make Ss know the contribution of Yuan,and learn his spirit and his simple life time.Teaching important and difficult points:(1) some words, expressions and sentence structures mentioned above;(2)the content of the text;(3)training their reading and speaking skills.Teaching methods: CLT, TBLT,QT.Learning strategies: CLS, QLS, TBLS.Teaching procedures:Step 1 lead-in: (1) teacher plays a piece of recent news from CCTV about the harvest of the super hybrid rice, and ask students whether they know Yuan or not, and talk about him and his contribution.(2)Brain storm: let Ss describe Yuan in their minds including his appearance, his living condition and so on.Step 2 fast reading tasks:(1)teacher introduces Yuan and super hybrid rice(2)make Ss read the text as fast as possible with questions. Such as: what’s the general ideaof this passage? What’s Yuan’ dream? (skimming and scanning skill)Step 3 intensive reading tasks(1)let Ss read the text silently, find topic sentence of each paragraph and draw the difficult sentences and the knowledge what they don’t understand.(words guessing)(2)teacher and Ss talk about the important words, expressions and sentences together, and ask Ss to retell the content of the text.(summarizing and paraphrasing)(3)teacher summarize this part.(4) read again following the courseware.

在接下来的细读环节,我套用了高考对阅读理解的考查方式设置了5个问题,分别为三个推理判断题,一个细节题和一个主旨大意题。学生需要对文章的内容进行分析、归纳、推理、猜测等高级思维活动才能做出正确的回答。【设计意图】这一过程是对学生进行细读的训练,培养学生获取特定信息和挖掘文章深层次信息的能力。第三环节:Intensive-reading (精读) 15′第三个环节精读,既是最重要的环节,也是突破本课重难点的关键。首先,让学生思考剧本中人物看到百万英镑前后的态度发生了怎样的变化。其次,让学生仔细阅读文章,找出可以表现人物态度变化的具体的语言和动作。最后,让学生总结人物的态度发生变化的根本原因是什么,从而引出Money Talks, 供学生思考。【设计意图】通过一系列的活动培养学生学习从人物的语言和动作探究人物的心理,使学生进一步体会戏剧语言的魅力,从而对文章背后所反映的社会问题进行思考,也为下一步的讨论环节做好铺垫。

In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid. VII. Blackboard design:

通过写文章梗概,培养学生综合运用语言的能力,学习用恰当的英语描述科学家的故事。这是本课的教学难点。教师可以使用完形填空的方式来帮助学生整理语篇,从而来降低难度。本课的教学重点的突破方法是:在阅读前,让学生初步了解得出科学观点所需要的基本程序,从而轻松而自然地导入文章的阅读;在阅读过程中,由易到难设计快速阅读和精读的问题,层层推进各种阅读活动,让学生对阅读内容从整体感知到细节理解,最后深层读懂整篇文章,同时加强阅读策略的指导,让每个学生都主动参与课堂教学活动,最终达到提高阅读能力的目的。Step 4 Post-readingGroup Activities四人小组共同合作,在老师的适当指导下,就以下2个问题展开讨论,让学生就所知、所学、所感和所想融入话题,然后抽若干同学代表作小组发言。1. What do you think about John Snow, and what should we learn from him?2. Cholera was 19th century disease, which two diseases are similar to cholera today? Why?

各小组派代表汇报。4、教师提出问题组织学生讨论:⑴要想了解更多的绿色食品,了解绿色食品的销售情况,我们应该怎么做?⑵要想了解广大消费者对绿色食品的态度,食用绿色食品的意义,是否懂得辨认绿色食品,以及什么样的人群对此知识最缺乏等,我们应该怎么做?组织学生汇报交流。5、做个“绿色食品”广告设计师。为你喜欢的绿色食品设计广告语,每组推荐一个。6、让学生了解绿色食品认证程序。7、绿色食品打“假”队员在行动。8、向学生介绍生态绿色食品基地。三、活动总结:通过研究、探讨,了解学生对绿色食品的态度。提问:民以食为天,吃,是一个大问题,如果你的爸爸妈妈让你到超市买牛奶、方便面等,你会选择什么样的食品?为什么?希望通过今天的学习,同学们能够做到绿色消费,也希望你们向自己的家人、向周围的了解学生对“无公害食品”、“有机食品”与“绿色食品”的认识。

分析过焦作市的地理概况和产业优势后,就需要针对由于资源枯竭所带来的问题提出合理化的建议。既然是谈经济转型,就应该将话题的范围明确在这一领域内。通过材料3的相关内容,我们了解到焦作市需要在产业结构调整、培育新的优势产业、增强综合竞争力等三个整改方针上下功夫。因而引导学生针对优势与不足提出建议,以三个整改方针为基准,衡量建议的可行性是锻炼学生解决此类问题的有效途径。在此我将教会学生的是解决问题方法而非案例的内容,正所谓“授之以鱼,不如授之以渔”。接下来针对学生的建议和教材资料分析所罗列的10点整改思路,由学生自由发言提出看法,通过教师的指导和学生的讨论,进而确定经济转型建议的具体方案。最后注意将建议与产业优势相对照,看建议是否都是围绕着产业优势而提出的,这样做会加深学生的印象,通过建议和优势的对应关系,将不难找出此类问题的解题思路。

(一)、复习提问1、请说出功的计算公式及功的单位2、我们用哪个物理量表示物体运动的快慢?(二)、创设情景,引入新课1、播放多媒体素材,用起重机和一个工人搬运几百块砖比较哪一种方法好?图中的情景说明了什么问题?(教师通过所设计的情景,将学生引入怎样比较做功快慢,让学生发表自己的看法,初步知道物体做功是有快慢之分的。)(三)、进行新课1、比较做功快慢的方法播放多媒体素材并提出问题:怎样比较两个人谁做功快谁做功慢?教师启发:以前学习过要比较两物体运动的快慢,可以先确定路程再比较时间,也可以先确定时间再比较路程。在路程和时间都不同时,通过计算速度比较两物体运动的快慢。同理,要比较物体做功的快慢可采用什么方法?

探究一:高中阶段功的含义是什么?投影:初中九年级《物理》105页学生思考:①图中物体的势能、动能分别如何变化?②物体能量的变化和做功是否存在关系?学生:分组讨论,得出结论:如果物体的能量发生变化时,说明有力对物体做了功。教师:进行点评和小结(设计意图:对初中知识深化理论认识,并为以后功能关系的教学作准备)探究二:力对物体做功的两个要素是什么?情景再现:找体重相对悬殊的两位同学,①A同学试图抱起B同学,但没成功。②B同学抱起A同学在教室内匀速走动。学生思考:在①中,A是否对B做功?在②中,B是否对A做功?学生:分析得出做功的两要素:物体受到力的作用,并且在力的方向上发生位移.教师:让学生分别例举生活中力对物体做功和不做功的例子,(设计意图:让学生亲身参与课堂实验,烘托课堂气氛,相互协作增进同学情谊)探究三:如果物体的位移不再力的方向上,那么力是否还对物体做功?

通过这个示例呢,我们可以得到解决向心力问题的一般的步骤,确定对象,找出轨迹,找出圆心,然后进行受力分析,让同学们参考这样的步骤,逐步的解决圆周运动的问题,对于变速圆周运动,我通过链球运动进行引入,这里是一个链球运动的视频,在同学们观看视频之前,我给同学们提出问题,链球收到绳子的拉力,做的是匀速圆周运动吗? 然后再课堂上我们再做一个小实验, 我们可以通过改变拉线的方式来调节小球的速度大小吗? 那么对小球,做加速圆周运动,进行受力分析,我们可以看到,小球做加速运动时,他所受到的力,并不是严格通过轨迹的圆心,在进行分析的时候,特别强调,小桶所受力的切线方向分力,和法线方向分力,切线方向分力,改变小球运动速度大小,法线方向分力,改变了小球运动的方向,法线方向的分力,在这里就是向心力,产生了向心加速度,通过这样一个例子进行分析,同学们是比较容易理解的,

四、教学方法和学法。课前学生搜集有关《诗经》的资料必不可少。另外,时隔数千年,年代久远,文字的障碍很大,然而,过分纠缠于文字的疏通会破坏诗歌的“气”,丧失诗歌的“神”,所以在学习时,应舍去条分缕析的理论评价,指导学生结合注释疏通文字,然后引领他们经由文字再现形象和事件,经由形象和事件领略情感,感受其中浓浓的诗情。诵读的环节是重要的,配以二胡独奏《长相思》,营造意境,学生沉浸在音乐营造的意境中反复吟咏,读出节奏,读出音调,读出感情,细细体味,让或优或喜的情愫萦绕心间,我们就触到了先民的灵魂。比兴手法为《诗经》独创,重章叠句同样别致而新鲜,教学过程中结合具体语境让学生自己去发现并进行讨论,不搞枯燥的知识传授。还引入讲故事、改写两种活泼的学习形式,从而达到加深理解的目的。

我以以《登高》为例,引导学生进行意象分析,感悟意境美。古人云“立象以尽意”“古诗之妙,专求意象”意象是诗人情感的载体,是诗歌的灵魂。引导学生张开联想和想象的翅膀去感受,去体验是意象,诗歌鉴赏的关键。科林伍德说“真正艺术的作品,不是看见的,也不是听到的,而是想象中的某种东西。”诗人通过想象创造出诗的形象,我们读者通过想象丰富地再现诗人创造的形象。而感受体验则是以全部身心投入作品,心灵与心灵相沟通,感情与感情相交流,对诗人的想象活动进行再经历和再体验。因此,在引导意象解读中,我先让学生点击这一个,就是通过抓修饰词、依据感情基调、展开想象具体分析本诗中每个意象的情感意蕴和审美意蕴,使学生明白意象在每首诗中的独特性。

解析:材料是讲学习型社会所产生的影响,A项观点错误,在当前和今后相当长的时间里,学校教育仍然是人们获得知识的最重要的途径。B项观点错误,终身学习只是成就人生目的的手段、途径,而不是目的本身。D项说法错误,当前我国社会的中心工作是经济建设。二、问答题5.材料一:日本是公认的漫画大国,日本的动漫产业产值每年230万亿日元,成为日本的第二大支柱产业。在日本,漫画比电影、小说有时甚至比电视或音乐更受欢迎。日本漫画的热潮还席卷了世界:日本每年出口到美国的卡通片价值就达5 000亿日元,是日本对美国钢铁出口金额的4倍;漫画中的人物被迅速复制成电子游戏、卡通片及真人演出的节目。原来只是闲暇时候消遣的漫画,正飞速渗透到人们的生活中。值得警惕的是,除了催人奋进的精华之外,日本漫画中也存在暴力、色情、扭曲历史等诸多糟粕,对缺乏辨别能力的青少年产生了许多不良影响,更引发了一系列深刻的社会问题。

教学过程:(一)导入:课前放《爱的奉献》歌曲,同时不断播放一些有关“爱”的主题的图片,渲染一种情感氛围。师说:同学们,谁能说说这组图片的主题应该是什么?生(七嘴八舌):母爱,不对是亲情……是友情、还有人与人互相帮助……那组军人图片是说保卫国家,应该是爱国……那徐本禹和感动中国呢?…………生答:是关于爱的方面师说:不错,是关于爱的方面。那么同学们,今天就以“爱的奉献”为话题,来写一篇议论文如何?生答:老师,还是写记叙文吧。生答:就是,要不议论文写出来也象记叙文。师问:为什么?生答:老师,这个话题太有话说了,一举例子就收不住了,怎么看怎么象记叙文。生答:就是,再用一点形容词,就更象了。众人乐。师说:那么同学们谁能告诉我,为什么会出现这种问题?一生小声说:还不是我们笨,不会写。师说:不是笨,也不是不会写,你们想为什么记叙文就会写,一到议论文就不会了,那是因为同学们没有明白议论文中的记叙与记叙文中的记叙有什么不同,所以一写起议论文中的记叙,还是按照记叙文的写法写作,这自然就不行了。那好,今天我们就从如何写议论文中的记叙讲起。

(二)能力目标培养学生运用哲学理论观察、分析、处理社会问题的能力,增强学生的时代感。(三)情感、态度与价值观目标培养学生与时俱进的思想品质,让学生关注时代、关注现实、关注生活,逐步树立科学的世界观、人生观、价值观。三、说教学重难点:时代精神的总结和升华是本框的难点,虽然学生在文化生活中学习了文化与经济政治的关系,但要让学生得出哲学是时代精神的总结和升华,还要联系前面关于哲学的基础知识进行总结归纳,因此可能会难以把握,另外关于什么样的哲学是真正的哲学的理解会稍有难度。社会变革的先导是本框的重点,一方面哲学源于时代,另一方面强调哲学反过来对时代又有重要的反作用,突出这一点能够更好地激发学生学习哲学的热情和信心,对于后面知识的学习是极为有益的,因此社会变革的先导这一目作重点处理。

二、说学情本课的教学对象为高二学生,他们思维活跃已具备一定归纳能力和分析、综合能力,能够自主地分析现实生活中的一些文化行为,但看问题往往比较偏激、片面,缺乏良好的逻辑思维能力。所以,在文化创新的途径上要对他们进行指导,以免走入误区。三、教学目标根据新课程标准、教材特点、学生的实际,我确定了如下教学目标:【知识与能力目标】1.理解文化创新的根本途径和两个基本途径;2.了解文化创新过程中需要坚持正确方向,克服错误倾向。
