人教版新课标小学数学四年级下册小数的产生和意义说课稿
一、说教学内容本节课的教学内容是人教版小学四年级下册数学课本第50-51页的例1和做一做，以及第55页的练习九第1-3题。这一内容，既是前面在三年级“分数的初步认识”和“小数的初步认识”的基础上的延伸，也是系统学习小数的开始。要求学生明确小数的产生和意义，小数与分数的联系，掌握小数的计数单位及相邻两个计数单位之间的进率，从而对小数的概念有更清楚的认识。教材中简要呈现了“小数产生的”过程，通过实际测量黑板、数学课本，使学生体会小数的产生的原因。例1，教材分三个层次编排：先通过分米数改写成米数，说明十分之几的数用一位小数来表示；再通过厘米数改写成米数，说明百分之几的数用两位小数来表示；然后通过毫米数改写成米数，说明千分之几的数用三位小数来表示。
北师大版小学数学五年级上册《调查生活垃圾》说课稿
（三）探究新知，建立模型这一环节是课堂教学的主体部分，是学习知识、培养能力的主要途径。先是让学生独立思考，讨论交流，在具体的生活情境中让整个学习过程充满生活气息，使学生学会借助生活经验思考探索问题，培养他们运用数学知识解决日常生活中的实际问题的能力，获得分析问题和解决问题的一些基本方法，培养应用意识。（四）归纳总结，发现规律通过总结，使学生盲目无序的思考变得有序，使生活化的思维方式得以数学化，使宽泛肤浅的认识得以提炼和升华。（五）巩固练习，拓展延伸通过学习，了解学生本节课的掌握情况。体现了数学的真正价值，数学来源于生活，又应用于生活。（六）课堂小结，课后延伸使学生在重温学习的过程中获得积极的情感体验，使知识的脉络更清晰。
北师大版小学数学六年级上册《生活中的比》说课稿
（一）教材分析本节课是在学生已经学过除法和分数的意义以及分数与除法的关系的基础上进行教学的。由于学生在理解比的意义上比较困难，教材并没有采取直接给出“比”的概念的做法，而是密切联系学生已有的生活经验和学习经验，提供了多种情境，引发学生的讨论和思考，让学生体会引入比的必要性，感受比在生活中的广泛存在，也为“比的应用”“比例”等后续学习做好铺垫。（二）教学目标在认真分析教材的基础上，结合学生实际，我从知识、能力、情感等方面拟定了本节课的教学目标：知识目标：经历从具体情境中抽象出比的过程，理解比的意义，能正确读写比，会求比值。能力目标：培养学生自主学习、独立思考，能利用比的知识解决一些生活中的数学问题。情感目标：引导学生广泛联系生活实际，充分感受数学知识的美与乐趣，激发学生的求知欲望。
人教版新课标小学数学四年级上册数的产生说课稿
一、创造性地使用教材。上课前，我就布置了学生收集相关的“数”的产生的资料，初步感知“数”的产生历史及变化过程；上课后，我将数位的产生融入“数的产生”这样大的背景中，使学生感受数学王国的博大与神奇。二、把学习的主动权利教给学生，放手让学生去探索、去发现，给予学生思维的空间。如：我在教学“探索十进制计数法”一节时，给学生提供一张不完整的数位顺序表，让学生填写完整并说出依据。学生通过自己动脑思考、动手填写，就会发现“相邻两计数单位间的进率都是十”，既而明白：相邻两单位进率是十的计数法就是十进制计数法，课堂效果十分明显。三、困惑与反思：本节课对十进制计数法教学法的设计虽然取得了较明显的效果，但对于“数位”、“位数”、“计数单位”这些概念该不该讲？怎样讲才能让学生理解得更透彻，我感到困惑。
人教版新课标小学数学一年级上册生活中的数教案
六、教学反思 从这节课的实施情况看，课堂实施与原先的公开课教案是比较一致的，效果也是比较好的，主要体现于以下两点： 1、效果得益于“跳出”--跳出教材框框 刚开始备课和试教时，我打算充沛利用教材，根据教材上的内容出示幻灯片让同学说一说，但一节课下来显得很单调、信息量很少，体现不出生活中数的味道。于是我开放教材，跳出教材的框框，课前安排一个“找生活中的数”实践活动把同学放到社会生活之林中去，让他们先找些“野食”吃。这样，课前在准备过程当中积累的素材多了，同学的学习效益大大提高了。同学在丰富多彩的实际生活中自由自在地采撷自身感兴趣的“果子”，他们采来的“果子”是绚丽多姿的，然后回到课堂交流，共享到了“果子”的丰富，起到“以一当数十”的作用。 这个“跳出”战略，体现了现代科学“系统论”的理论。系统论认为：系统只有开放，不时吸收外界的信息，才干使自身“有序”。

初中化学人教版九年级上册《实验活动3燃烧的条件》教案
【学习目标】1．知识与技能：加深对燃烧条件的认识，进一步了解灭火的原理。2．过程与方法：体验实验探究的过程，学习利用实验探究的方法研究化学。3．情感态度与价值观：利用化学知识解释实际生活中的具体问题，使学生充分体会到化学来源于生活，服务于社会。【学习重点】通过物质燃烧条件的探究，学习利用控制变量的思想设计探究实验，说明探究实验的一般过程和方法。【学习难点】利用控制变量的思想设计对照实验进行物质燃烧条件的探究。【课前准备】《精英新课堂》：预习学生用书的“早预习先起步”。《名师测控》：预习赠送的《提分宝典》。情景导入 生成问题1．复习：什么叫燃烧？燃烧条件有哪些？今天自己设计实验来进行探究。2．明确实验目标，导入新课。合作探究 生成能力学生阅读课本P150的相关内容并掌握以下内容。实验用品：镊子、烧杯、坩埚钳、三脚架、薄铜片、酒精、棉花、乒乓球、滤纸、蜡烛。你还需要的实验用品：酒精灯、水。1．实验：用棉花分别蘸酒精和水，放到酒精灯火焰上加热片刻。上述实验中我们能观察到什么现象？说明燃烧需要什么条件？如果在酒精灯上加热时间较长，会发生什么现象？答：蘸酒精的棉花燃烧，蘸水的棉花没有燃烧，说明燃烧需要有可燃物。如果加热时间较长，水蒸发后，蘸水的棉花也会燃烧。2．如图所示，进行实验：我们能观察到什么现象？说明燃烧需要什么条件？答：在酒精灯火焰上加热乒乓球碎片和滤纸碎片，都能燃烧，说明二者都是可燃物。放在铜片两侧给它们加热后可看到乒乓球碎片先燃烧，说明燃烧需要温度达到可燃物的着火点。3．你能利用蜡烛和烧杯(或选择其他用品)设计一个简单实验证明燃烧需要氧气(或空气)吗？答：点燃两支相同的蜡烛，然后在一支蜡烛上扣住一只杯子，看到被杯子扣住的蜡烛一会儿就熄灭，说明燃烧的条件之一是需要氧气。
人教版高中语文必修3《爱的奉献 学习议论中的记叙》说课稿
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。
人教版高中语文必修3《语文学习的自我评价》教案
一、语文学习中学生自我评价能力的培养1．营造氛围，培养学生自我评价的意识。学生自我评价能力是教师长期培养的结果，而保护学生自我评价的热情，更是持续自我评价的保证。在我们的实际教育教学中，教师一直处于评价的绝对主体，很少去关注学生自我评价意识和能力的培养，学生常常不理解：为什么要认真听讲？为什么书写要工整、为什么发言要积极？为什么老师、父母对考试分数会有那么高的要求？当前出现的学生许多诸如“离家出走”、“毒杀亲人”等教育、行为、品德方面的问题，我想其中除了家长、教师的评价意识和评价艺术等原因之外，学生的自我评价意识的缺乏是根本的原因。所以我认为，学生自我评价意识的培养刻不容缓。（1）热情鼓励，提供成功的心理体验。在教学过程中，教师要善于发现、肯定学生自我评价的点滴进步，对于他们每一点进步都要真诚热情地鼓励。让学生觉得我这么做，这么想是对的。让学生在教师的鼓励中体会到强烈的爱，感受到自己的进步，增强自己的信心。“心若在，梦就在！”教师的热情鼓励是一种强大的催化剂，促使学生在学习中乐于自我评价。

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教学设计
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.
新人教版高中英语必修3Unit 1 Festivals and Celebrations-Reading for writing教学设计二
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.
