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.
1. 这个寓言是一个关于一位国王古寓言。 The fable is an old fable about a king.2.作者用这个故事让读者对于社区的问题负有个人责任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 这个故事十分成功的实现了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3. Does the writer give his or her opinion about the character or their actions ?4. Is the review well-organised ? 5. Does the writer use the -ing form as the adverbial correctly in the writing ?6. Are there any grammar, spelling, or punctuation errors ?Step 9 HomeworkPut up your revised draft in the classroom or read it to your class.
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

一、人类遗传病1.概念2.分类(1)单基因遗传病(2)多基因遗传病(3)染色体异常遗传病①原因②类型3遗传病的特点4.遗传病对人类的危害八、说布置作业在作业的布置中,我严格遵循“重质量、轻负担”的指导思想。第一题主要是为了帮助学生及时纠正原有的对知识的错误理解或片面认识,培养学生的解题技巧和技能。所以我选用了该题。同时想借助该题培养学生对问题的科学的思维方法和探究的精神。帮助学生提高对信息技术运用的熟练程度,发展学生的信息素养。附作业:1、连线题,请同学们连线指出下列遗传各属于何种类型?(1)苯丙酮尿病 A、单基因遗传病(2)21三体综合征(3)抗维生素D佝偻病 B、多基因遗传病(4)软骨发育不全(5)青少年型糖尿病 C、常染色体病2、以生物小组为单位进行人类遗传病的调查。
在学生活动的基础上,教师总结归纳:要坚持从群众中来到群众中去的工作方法。要求:政府要通过各种途径,利用各种群众组织、社会团体广泛收集群众意见和建议,认真对待群众的来信来访。还要为群众诚心诚意办实事,尽心竭力解难事,坚持不懈。通过合作探究,以此来培养学生的分析能力,探究能力以及透过现象看本质的能力,培养学生获取信息的能力,自主学习的能力以及全面看问题的能力,再结合教师的讲授,给学生一种茅塞顿开的感觉。环节四 回归生活 提升情感我将引导学生阅读课本,通过设置活动探究课,结合生活实际从时效,便利,实效等方面请学生评述公民求助或投诉的四种方式的特点和优点。在这一过程中,我还会用多媒体展示常用的热线电话,政府网站上有关信访、政务公开及其他便民利民的栏目,丰富课堂资源。让学生阅读课本,自行归纳知识点,有助于培养学生自主学习能力。
在讲述细胞分化的意义时,也可以用实例来解决,工厂的生产车间里不同的工人干着不同的工作,一件产品的产出需要这些工人才能创造出来,一个生物体就像一个车间一样,不同的细胞各司其职,相互合作。工人的分工是主管调解出来的,而不同细胞的出现就是细胞分化的结果,所以说,细胞的分化是生物体发育的基础。在讲到细胞全能性的时候,要多给学生举些关于细胞全能性的例子,如植物组织培养、克隆技术等等,让学生从实际的例子中真正的悟出细胞全能性的含义。此外,还要重视教材中的疑问,适当对题目进行引申,使它的作用更加突出,有利于学生对知识的串联、积累、加工,从而达到举一反三的效果。怎样来解释细胞的全能性呢?这主要以讲授法来解释了,细胞全能性的体现需要在组织或器官离体后才能体现出来,每个细胞都包含着生物体的全套遗传基因,通过基因选择性的表达,使离体的组织或器官通过分裂和分化逐渐发育成完整的植株。
(3)如何做到兼顾效率与公平?这部分知识点我结合上面的图片,设疑:“请大家对这一社会现象进行讨论,我们如何才能做到既坚持效率又兼顾公平?”导入这部分的分析。学生在讨论的过程中对如何兼顾效率与公平已经形成了一定的见解,结合图片,为兼顾效率与公平献计献策,寻求两者的最佳结合点。幻灯片展示:怎样才能做到兼顾效率与公平?第一,允许和鼓励一部分地区和个人通过诚实劳动和合法经营先富起来,带动其他地区和个人致富,最终达到共同富裕。第二,既要反对平均主义,又要防止收入差距悬殊。既要落实分配政策,又要提倡奉献精神;在鼓励人们创业致富,提倡回报社会和先富帮后富。第三,必须正确处理初次分配注重效率与再次分配注重公平的关系。在讲授过程中,还展示大量图片。结合图片分析。设计意图:体现课堂上学生的主体地位,让学生在观看中体验,在讨论中升华,从而体会构建和谐社会的重要意义。
一、对教材内容的处理根据新课程标准的要求、知识的跨度、学生的认知水平,我对教材内容有增有减。二、教学策略的选用(一)运用了模拟活动,强化学生的生活体验,本框题知识所对应的经济现象,学生已具有了一定的生活体验,但是缺乏对这种体验的深入思考。因此在进一步强化这种体验的过程中进行了思考和认知,使知识从学生的生活体验中来,从学生的思考探究中来,有助于提高学生的兴趣,有助于充分调动学生现有的知识,培养学生的各种能力,也有助于实现理论知识与实际生活的交融。(二)组织学生探究知识并形成新的知识我从学生的生活体验入手,运用案例等形式创设情境呈现问题,使学生在自主探索、合作交流的过程中,发现问题、分析问题、解决问题,在问题的分析与解决中主动构建知识。也正是由于这些认识来自于学生自身的体验,因此学生不仅“懂”了,而且“信”了。从内心上认同这些观点,进而能够主动地内化为自己的情感、态度、价值观,并融入到实践活动中去,有助于实现知、行、信的统一。
Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
f.有丝分裂的意义(讨论分析教学),首先引导学生结合所学知识讨论有丝分裂的的作用,最后有教师归纳总结,并要求学生在理解的基础上记忆。g.无丝分裂(图形直观教学、简介),本部分内容不是教学的重点,内容也相对简单,所以我的教学方法是直接给学生展示挂图,再进行简短介绍,让学生了解即可。h.引出减数分裂的概念,为第五章学习打下基础。小结:新课讲完以后由教师对本节内容进行总结巩固和反馈:进行一些课堂练习达到巩固和反馈的作用。最后布置作业,各种难度的作业题目均设置一些,其中简单题比重大,难题要求学生选作,这样提高学生学习积极性。2教学媒体程序设计: 细胞周期的概念(多媒体课件演示周期动画)植物细胞有丝分裂(多媒体课件演示分裂各期动画)动植物细胞有丝分裂异同点(多媒体课件演示分裂各期动画)有丝分裂过程中DNA和染色体数量的变化规律(挂图演示,包括表格和函数图象)
(1观察图解,色盲基因在性别间是如何传递的呢?(女--女、女--男、男--女)(2)为什么不能由男性传给男性?(色盲基因是在X染色体上,因此色盲基因是随X染色体的传递而传递。)(3)男性的色盲基因怎样才能传给男性呢?(通过女儿,传给外孙即交叉遗传)(4)从图解看色盲在男女中的发病情况怎样?(男性多于女性)(5)从社会调查也是这样,你是否能从基因和染色体的角度加以解释?(提示:女性染色体的构成,结合基因位置及显隐性进行分析)归纳特点:归纳出色盲基因遗传的特点并扩展到X染色体隐性遗传的特点上。色盲基因遗传(X隐性遗传)的特点:(1)男患者多于女患者(2)交叉遗传(3)女病儿子必病,男正女儿必正等。问题探讨:利用“遗传图解”结合“问题链”继续探讨,拓展到抗维生素D即X 染色体显性遗传的特点。(6)色盲基因在X染色体上属隐性基因,子代表现男多于女,对应的正常色觉基因则属于X显性基因,子代表现应如何?(女多于男)
三、孟德尔遗传规律的现代解释①分离定律:在杂合体的细胞中,位于一对同源染色体上的等位基因,具有一定的独立性;在减数分裂形成配子的过程中,等位基因随同源染色体的分开而分离,独立地随配子遗传给后代。②自由组合定律:位于非同源染色体上的非等位基因的分离或组合是互不干扰的;在减数分裂过程中,同源染色体的等位基因彼此分离的同时,非同源染色体上的非等位基因自由组合。总结:再次强调孟德尔遗传定律的现代解释课堂练习:书本31页6、教学反思:本节课设置了一系列问题情境,层层设问,在学生答问、质疑、讨论过程中让学生建构新概念和新的知识体系,并通过教师及时掌握反馈信息,适时点拨、调节,让学生在推理判断中培养良好的思维习惯和对知识的迁移能力,而且通过留出一定的时间让学生提问,体现了以学生为主体的思想。
四、说教学程序(一).温故知新、导入新课复习提问:基因突变导致生物变异的原因是什么?回答:基因突变是基因结构发生改变,从而使遗传信息改变,使蛋白质结构改变、生物性状改变,即生物发生了变异。那么,基因是什么?它和染色体又有何关系?回答:基因是有遗传效应的DNA片断,染色体是DNA的载体,基因在染色体上呈线形排列。引出新知:对于一个生物体来说,正常情况下,其染色体的结构和数量都是稳定的。但在自然条件或人为因素的影响下,染色体的结构和数量均会发生改变,从而导致生物性状的改变,这就属于染色体变异。(二).把握重点、突破难点重点的把握:1、染色体结构的变异播放影片:猫叫综合征幼儿。让学生观察: 患儿哭声轻、音调高,很像猫叫。教师补充: 患儿的征状---两眼较低、耳位低下,存在着严重的智力障碍。阐述病因---染色体片段缺失
一、说教材(一)说教材的地位和作用《股票、债券、保险》是人教版必修1《经济生活》第六课,第二框题的内容。本框题承接前面“企业与劳动者”:企业的发展资金从何而来,同时又为下一课“个人收入与分配”做好了铺垫,它在整个教材中起承上启下的作用。因此,本框题在《经济生活》中具有不容忽视的重要的地位。(二)说教学目标根据高一新课程标准要求,本教材的结构和内容分析,结合着高一年级学生的认知结构及其心理特征,我制定了以下的教学目标:1、知识目标(1)股票的含义、收益、特点和发展股票市场的意义。(2)债券的含义与分类(3)商业保险的含义与订立原则2、能力目标(1)重点培养学生辩证思维的能力,发现和分析、解决问题的能力。3、情感、态度与价值观目标培养科学理财的意识,形成“投资理财,利国利己”的观念。(三)说教学的重、难点本着高一新课程标准,在吃透教材基础上,我确定了以下的教学重点和难点
(2)、市场调节存在固有的弊端:自发性:由于市场调节是在价值规律自发作用下进行的,在利益驱动下会产生一些违反市场原则的行为,如制造、销售假冒伪劣商品,大量排放废水、废气破坏环境,窃取他人智力成果等等。盲目性:由于人们不可能完全掌握生产各方面信息及其变化趋势,致使决策带有一定的盲目性。如某种商品有利可图则一哄而上,反之则一哄而退,从而造成资源浪费和消费得不到充分满足。滞后性:由于市场价格的形成和传递有一个过程,一旦传递到生产经营者手中进行生产调整,就有一个时间差,致使市场调节带有滞后性,成为一种事后调节。教师活动:请同学们想一想,市场的这些弊端和不足,会导致什么后果?(3)、危害教师总结:资源浪费,经济波动与混乱,分配不公两极分化等。设计意图:通过创设情景,加深对市场调节局限性的理解;要求学生结合生活实例探讨其弊端有助于加强对其产生原因和表现的记忆和理解。
2、传授新知与学生展示(35分钟) 先由老师点出本课的知识点,它包括:(1)经济全球化深入发展:结合课本91-93页理解经济全球化的含义;经济全球化的表现:生产全球化,贸易全球化,资本全球化;跨国公司是实现经济全球化的载体。(跨国公司的含义、目的、作用分别是什么)(2)经济全球化的影响: 经济全球化的实质:以发达资本主义国家为主导的经济全球化;消极影响积极影响;如何应对经济全球化。讲完了知识点,接着回归图片和书本的材料,给学生留下三个问题进行小组讨论:A :谈谈你感受到的经济全球化B :怎样理解经济全球化是一把“双刃剑”C:假如你是一位企业经营者,面对经济全球化趋势,你会怎么做?先完成讨论的小组可举手示意老师给予检查,老师根据需要抽查同学到讲台进行展示讨论的结果,并对表现突出的小组进行当堂奖励。
