2、系统的基本特征系统观念为人们把握复杂事物提供了一系列科学方法和原则。第一,整体性原则。第二,有序性原则。第三,优化原则。学生的兴趣被激发,可以再调起高潮,让学生听一首歌曲,三个和尚挑水,让学生从愉快的歌声中,明白一个道理:“三个和尚没水喝”,导致这一结果的根本原因就在于人数虽然多了,但没有形成合理的结构,不是相互支持,相互促进,而是相互制肘、相互消磨,结果各要素的力量或作用被内耗了,出现了1+1<2的效应。所以,就要求我们一定要做到:3、掌握系统优化的方法的要求(1)着眼于事物的整体性;遵循系统内部结构的有序性;注重系统内部结构的优化趋向。(2)用综合的思维方式来认识事物巩固练习:以巩固知识为基础,培养能力为目标。

②关于哲学的第二个问题是——思维和存在有没有同一性解释同一性——就是说意识(思维)能否正确认识物质(存在)的问题。(让学生表达他们自己的意见)总结得出三种看法——认为意识(思维)可以正确认识物质(存在)的,属于可知论者;凡是认为意识(思维)不能正确认识物质(存在),属于不可知论者。当然也有些同学是两者观点都有,这种同学我们把他称为不彻底的不可知论者。2、为什么思维和存在的关系问题是哲学的基本问题(1)它是人们在生活和实践活动中首先遇到和无法回避的基本问题(举例说明问题,吃饭的时候吃什么菜,学习计划与学习的实际等等)结合教材P10探究进行讲解举例:11月31日请全班同学吃雪糕,吃完后再去肯德基大吃一顿,之后再到卡拉OK唱通宵——不切实际,因为11月并没有31日。(2)它是一切哲学都不能回避、必须回答的问题(不同的回答,直接决定着哲学的不同发展方向。)

1、课题引入:11月16日9时40分许,甘肃庆阳市正宁县榆林子镇发生一起重大交通事故,“校车安全”又一次甚嚣尘上,我设计提问“校车安全事故然表面是偶然,但又是一种必然,你认为事件的原因何在?”的问题激发学生的阅读兴趣。我设计典型事例,通过学生讨论,教师总结的形式,并得出主次矛盾辩证关系的原理分析。2、具体分析事件背后的原因,从原因中发现,这众多的原因矛盾中,都有主次方面之分,由于得出矛盾的主次方面原理。3、从原因中,寻找对策,既坚持重点论与两点论的结合。反对一点论和均衡论。4、无独有偶,在2011年在湖南,海南,广西等地均有类似的事件发生。对比各地事故背后的原因,得出应具体问题具体分析。进而分析具体问题具体分析的意义及地位。

5.课堂练习,夯实基础。得出原理方法论之后,给学生一分钟时间记忆,然后一名或几名学生上讲台默写,其他同学相互提问。针对这一基本概念,设置一道选择题。6、播放黄宏、宋丹丹小品《回家》片段,引发学生的兴趣,接着教师展示几幅关于手机的图片,然后让学生结合图片,进行讨论交流解决“合作探究二”,然后进行抢答(可以引发学生的竞争,从而调动课堂气氛)。教师在学生回答基础上,引导学生得出发展的实质这一结论,接着教师展示“如何判断一个事物是新事物还是旧事物的标准”,结合这一标准,让学生判断“电脑科技算命是不是新事物”,学生很容易就可以得出结论。7.教师简单总结刚刚学过的内容,引出“运动、变化是不是发展?”然后让学生讨论交流“合作探究三”。然后进行抢答,教师在学生回答基础上,稍加点评,给予积极地评价,然后展示答案。8.教师引导学生得出本节课的第二个原理与方法论,并让学生当堂记忆,可以简单提问。然后做课堂达标题,在学生展示答案后,教师简单点拨即可。

四、说学法哲学知识是比较抽象的,大多数学生都觉得哲学的内容很难把握,因此,针对学生的实际情况,在教学中必须发挥学生学习的主动性。通过观察、教师的引导及讨论来加深理解;通过练习来巩固所学知识。1.观察法:引导学生观察生活中的现象,加深理解发展的普遍性和发展的实质。2.探究法:让学生在讨论中体会发展的永恒性,知道用发展的观点看问题。3.练习法:“温故而知新”,学以致用,及时给一些习题让学生练习,让他们更能把握教材内容。五、说教学过程:[导入新课]引用一个历史故事来导入新课。(利用多媒体课件展示)[讲授新课]第一目:发展的普遍性①、自然界是发展的。(展示人的进化过程的图片和青蛙成长过程的图片,结合教材的例子来说明自然界是发展的)

“蛟龙号”深潜器的总设计师——中船重工第七〇二研究所的徐芑南,他先后三次被评为江苏省和无锡市劳模,曾被评为上海市科技功臣,有十几个国家、部、省、市级科技进步奖项与他的名字相联。在徐芑南眼中,这些都只是“副产品”,为国家设计出最需要的潜水器,让中国具备从“浅蓝”走向“深蓝”的能力,这才是他最大的愿望。每当说到大洋的海底世界,徐芑南的语速快了起来:“海底有好多资源,等着我们去发现、去利用,我们不能落在别人的后面!”海底有石油,海底有许多未知的生物,还有锰结核、钴结壳、热液硫化物……“蛟龙号”的立项目的就是为了探明神秘的深海世界,造福人类。探究活动二:结合材料和教材,阐述创新与人类思维方式变革的关系。(设计意图)通过学生们感兴趣的材料,对本课的教学难点加以突破。

新课程要求学生知识的获得由静态预设到动态生成。作为唯物辩证法的一个总特征、用联系的观点看问题是学生遇到的第一个辩证法思想。本教学设计由日常生活中我们所熟知的情境入手引申到联系的概念、使学生领悟到成语中蕴藏着丰富的哲理。而后通过分析日常生活中的事例一一讲解联系的普遍性、客观性和多样性、体现出生活处处有哲学的理念,符合学生的认知规律。在教学过程中、本教学设计安排了必要的学生活动、锻炼了学生的思维、充分发挥了学生的主体作用。在这一过程中,知识、情感、态度、价值观目标也得到了实现。具体分析如下:第一、这节课利用多媒体教学方式,把书本与丰富多彩的社会生活联系在一起。扩大了学生的眼界和见闻,打破了课堂学习时空的局限,打开了学生思维的心扉,使学生不断产生浓厚的兴趣和探究社会真谛的热情,并真正成为学习的主人,使学生真正成为教学过程的主体。

一、 学情分析根据新课程的核心理念:课程教学要以学生发展为本,让学生主主动参与是新课程实施的核心。所以我们要了解学生的基本情况。一方面:在高二阶段学生的思维能力从总体上看,正处于急剧发展、变化和成熟的过程中,他们急迫要去了解认识不断变化的社会。另一方面:此阶段的学生知识储备还不够、阅历浅,对于社会历史的发展还停留在感性认识的基础上,还没有上升到理性的高度。因此对其进行本框的教学很有必要。二、 教材分析俗话说,教材是老师的教本,学生的学本。所以正确理解教材,对其进行资源整合很有必要。(一)本框内容结构《社会历史的主体》是人教版新课程标准实验教材高中思想政治教育必修4生活与哲学第四单元《寻觅社会的真谛》第11课第2框的内容,本框题包括两目:人民群众是历史的创造者;群众观点和群众路线。

“最佳实践者”活动凸显了“尊重劳动”的理念。运用历史唯物主义有关原理。说明为什么药“尊重劳动”。(10分)参考答案:①生产方式是社会存在和发展的基础,生产力是社会发展的最终决定力量,尊重劳动是尊重社会发展规律的必然要求;(3分)③人民群众是历史的创造者,尊重劳动是尊重人民群众社会实践主体地位的要求;(2分)④尊重劳动是以人民群众利益为最高价值标准的必然要求;(2分)⑤劳动者的价值通过劳动实现,尊重劳动是尊重实践、提高劳动者积极性和创造性的必然要求。(3分)七、教学反思本节课教学目标明确,教学重点、难点设置恰当,教学过程详略得当,教学过程流畅。教师充分利用时政热点和生活故事,创设情景,使学生融入教学活动过程之中,充分发挥了学生的主体作用,在体验中提高了认识能力和知识水平,促进了学生的理解能力、思维能力和解决问题的能力,促进了学生的发展。

对数与指数是相通的,本节在已经学习指数的基础上通过实例总结归纳对数的概念,通过对数的性质和恒等式解决一些与对数有关的问题.课程目标1、理解对数的概念以及对数的基本性质;2、掌握对数式与指数式的相互转化;数学学科素养1.数学抽象:对数的概念;2.逻辑推理:推导对数性质;3.数学运算:用对数的基本性质与对数恒等式求值;4.数学建模:通过与指数式的比较,引出对数定义与性质.重点:对数式与指数式的互化以及对数性质;难点:推导对数性质.教学方法:以学生为主体,采用诱思探究式教学,精讲多练。教学工具:多媒体。一、 情景导入已知中国的人口数y和年头x满足关系 中,若知年头数则能算出相应的人口总数。反之,如果问“哪一年的人口数可达到18亿,20亿,30亿......”,该如何解决?要求:让学生自由发言,教师不做判断。而是引导学生进一步观察.研探.

例7 用描述法表示抛物线y=x2+1上的点构成的集合.【答案】见解析 【解析】 抛物线y=x2+1上的点构成的集合可表示为:{(x,y)|y=x2+1}.变式1.[变条件,变设问]本题中点的集合若改为“{x|y=x2+1}”,则集合中的元素是什么?【答案】见解析 【解析】集合{x|y=x2+1}的代表元素是x,且x∈R,所以{x|y=x2+1}中的元素是全体实数.变式2.[变条件,变设问]本题中点的集合若改为“{y|y=x2+1}”,则集合中的元素是什么?【答案】见解析 【解析】集合{ y| y=x2+1}的代表元素是y,满足条件y=x2+1的y的取值范围是y≥1,所以{ y| y=x2+1}={ y| y≥1},所以集合中的元素是大于等于1的全体实数.解题技巧(认识集合含义的2个步骤)一看代表元素,是数集还是点集,二看元素满足什么条件即有什么公共特性。

函数在高中数学中占有很重要的比重,因而作为函数的第一节内容,主要从三个实例出发,引出函数的概念.从而就函数概念的分析判断函数,求定义域和函数值,再结合三要素判断函数相等.课程目标1.理解函数的定义、函数的定义域、值域及对应法则。2.掌握判定函数和函数相等的方法。3.学会求函数的定义域与函数值。数学学科素养1.数学抽象:通过教材中四个实例总结函数定义;2.逻辑推理:相等函数的判断;3.数学运算:求函数定义域和求函数值;4.数据分析:运用分离常数法和换元法求值域;5.数学建模:通过从实际问题中抽象概括出函数概念的活动,培养学生从“特殊到一般”的分析问题的能力,提高学生的抽象概括能力。重点:函数的概念,函数的三要素。难点:函数概念及符号y=f(x)的理解。

人教版新课标教材必修一的“表达交流”部分,有一个专题是“人性的光辉——写人要凸显个性”。其中的“写法借鉴”部分列举了两则人物描写实例,并归纳出人物描写的几个要点。其训练的思路和方法是很明显的,但所列举的人物描写的实例却不够典型。而必修一第三单元正好是学习写人记事散文,其中的两篇自读课文《记梁任公先生的一次演讲》《金岳霖先生》又是写人记事非常典型的文章,故而我尝试将这两篇文章作为实例和。写人要凸显个性。写作指导结合起来教学。这样设计还有一个目的,那就是解决课程改革中教学内容多而课时紧张的矛盾,提高课堂教学效率。师:今天,我们一起来学习“写人要凸显个性”。这两堂课分四个步骤来完成:一、先学习教材中关于写人方法的介绍,约15分钟;二、快速阅读第三单元的《记梁任公先生的一次演讲》和《金岳霖先生》两篇文章,具体感受其写人的方法,约30分钟;

The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

4.That was an experience that frightened everyone. →That was _____________________. 答案:1. taking 2. being discussed 3. in the reading room 4. a frightening experienceStep 6 The meaning and function of V-ing as the predicative动词-ing形式作表语,它通常位于系动词后面,用以说明主语“是什么”或“怎么样”一种表示主语的特质、特征和状态, 其作用相当于形容词; 另一种具体说明主语的内容, 即主语等同于表语, 两者可互换。The music they are playing sounds so exciting. 他们演奏的音乐听起来令人激动。The result is disappointing. 结果令人失望。Our job is playing all kinds of music. 我们的工作就是演奏各种音乐。Seeing is believing. 眼见为实。Step 7 Practice1. It is ________(amaze) that the boy is able to solve the problem so quickly.2. Buying a car is simply _______(waste) money. 3. Please stop making the noise—it’s getting ________(annoy). 4. complete the passage with the appropriate -ing form.La Tomatina is a festival that takes place in the Spanish town Bunol every August. I think many food festivals are __________ because people are just eating. however, this festival is _________ because people don't actually eat the tomatoes. Instead, they throw them at each other! the number of people ________ part in this tomato fight, can reach up to 20,000, and it is a very __________ fight that lasts for a whole hour. The _______ thing is how clean Bunol is after the tomatoes are washed away after the fight. this is because the juice form tomatoes is really good for making surfaces clean!答案:1. amazing 2. wasting 3. annoying4. boring interesting taking exciting amazing

The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2. Students can understand the past, the present situation of some festival around the world and why there are some changes about them.Step 1 Lead in---Small talkWhat festival do you like best ? Why ?I like the Spring Festivals because I can set off the fireworks, receive the lucky money and enjoy the Gala with my families.Step 2 Before reading---Pair workWhy do people celebrate different festivals ?The Spring Festivals is to celebrate the end of winter and the coming of spring and new life.The Mid-autumn Day is to celebrate the harvest and admire the moon.

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 topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2. Use the structure of the reading article and language.

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

1)他们在初中的生物学学习中已具备了一定的关于光合作用的基础知识,也做过“绿叶在光下制造淀粉”这个实验。2)他们具备物质转变和能量变化等相关的化学知识。3)在前面的《降低化学反应活化能的酶》一节的学习中已经学习过简单的对照实验和相关的实验设计原则,使本节课最后的实验设计得以顺利进行。4)他们具有一定的 分析问题的能力,实施问题探究教学是可行的。三、教法和学法根据上述对教材和学生的分析,本节采用以下教法和学法:1)实验法:以实验说明结论。生物学的教学就是实验的教学过程,实验的展示形式有学生分组实验、老师示范实验、动画和图片演示实验等,让实验现象说明问题,而不是直接让学生记住结论。2)问题探究教学发:以问题引发兴趣。整个教学过程要设置好问题,层层展开,层层递进,让新知识与旧知识融为一个整体,让学生在步步上升中攀登到知识的顶峰。3)比较学习法,同时采用多媒体辅助教学,解决光合作用抽象的过程。
