关于小学教师顶岗实习个人心得体会参考范文
在实习的日子里，我们主要负责二年级、五年级和六年级的体育课教学。在实习最开始的时候我们看指导老师上课，以一个“老师”的身份看他是如何上课的，学习他如何传授知识、驾驭课堂，如何控制授课时间等等。通过听课我发现教师不仅对知识和技能的把握很重要，对学生的课堂纪律、积极性的调动都很重要。只有把握好课堂纪律、学生学习的积极性，才能让我们的学生在上课的时候真正的学到运动技能，并真正达到锻炼身体的目的。

人教部编版七年级语文上册写人要抓住特点教案
【设计意图】本环节旨在引导学生明确如何围绕人物的精神品质和性格特点选择材料，刻画人物内在的个性特征。两个环节，从课内引申到课外实践，用思维导图的方式，直观易学。三、抓住细节，事中显神当我们写多件事情表现人物时，要处理好叙事的详略。详写的事情也不能面面俱到地展开叙述，而应该突出重点，要将概括叙述与具体叙述相结合，力求通过一些具体而微小的细节表现人物特点。1.例文引路，学习方法师：下面我们一起以魏巍的《我的老师》为例，学习多件事情叙述的详略安排，学习用细节刻画表现人物形象。（1）师印发并指导学生阅读魏巍的《我的老师》。（见《教师教学用书》P161第三单元写作的“例文评析”栏目）（2）明确阅读要求。课件出示：阅读要求①勾画出描写蔡老师的外貌、语言、动作、神态、心理等语句，体会语句表达的真挚感情。
人教部编版语文八年级上册人民英雄永垂不朽教案
这篇文章的语言既有说明文语言准确、严密的特点，又有新闻特写鲜明、生动的特点，请和大家分享你最喜欢的语句，并说明理由。(学生发言)1．准确、严密示例：据地质学家化验证明，这些浮雕至少能耐800年到1000年之久。明确：“据地质学家化验证明”交代数据来源；“至少”对时间进行限定。2．鲜明、生动示例一：深夜，起义的新军和市民，摧毁了湖广总督府门前的大炮，正向总督府里冲去。总督府内熊熊的火焰冒向天空；总督府的牌子，被打断在阶前；撕碎了的清朝的龙旗，被践踏在地上。明确：“摧毁”“冲去”“冒”“打断”“撕碎”“践踏”一系列动词，准确生动地表现了起义者大无畏的革命气概，也揭示了清朝腐朽的本质。示例二：一群男女青年学生，举着“废除卖国密约”的旗帜，慷慨激昂地来到天安门前。梳着髻子、系着长裙的女学生，在向市民们散发传单。人群高处，一个男学生正在向围着他的群众演说。愤激的青年演说者，怒形于色的人群，使整个浮雕充满了痛恨卖国贼、激动人心的气氛。
人教版高中语文必修2《想象世界学习虚构》教案2篇
虚构不等于说假话。它是一种源于生活，但高于生活的艺术真实。我们可以举个例子：我国公认的最权威最真实的史书是——《史记》，那么，大家认为《史记》里有没有虚构呢？有。必修一的《鸿门宴》里就有虚构。大家想：司马迁是哪个朝代的人？西汉汉武帝时。刘邦项羽是哪个朝代的？秦末时期。那司马迁不可能坐时光穿梭机到秦末去参加鸿门宴吧？既然他没不在场，那课文《鸿门宴》里人物的语言、动作、甚至是表情从何而来呢？对，是司马迁根据有限的史料加以补充，想象、虚构出来的。那么，同学们在写作文时，也可以不必拘泥于亲身经历的事情，毕竟生活是平淡的，毕竟大家的生活阅历也有限，有时候，我们发挥想象、虚构一个故事来反映生活的真实，也许更生动、也更典型。所以，近年来高考试卷中都提示考生：作文可以大胆想象，编写故事。按照编故事的方式不同，我们的虚构性作文又可以写哪些类型呢：小说，散文，童话，寓言，科幻，故事新编……
人教版高中语文必修2《直面挫折学习描写》教案2篇
《贫寒是福天道酬勤石智勇从挫折中奋起》也许是自幼的贫寒生活塑造了石智勇内向的性格，即使是胸挂金灿灿的奖牌接受全场观众欢呼，他的表情也是略显羞涩的。小时候吃不饱肚皮的经历让他至今在“最喜欢的东西”一栏还填写着“食物”二字，而“穷人的孩子早当家”的坚韧，却又是促成他今日辉煌的动力。中国举重队副总教练陈文斌赛后说道：“智勇这几年练得很苦，今天终于有了这样的成绩，这是天道酬勤的结果。石智勇的奥运会金牌是中国男举的一次突破，我们非常激动。”在希腊神话里，命运女神总是让英雄历经磨难。石智勇也不例外。四年前的悉尼奥运会前夕，他在一次训练中扭伤脚踝，失去了参赛机会。“当时我伤心极了，不敢看电视直播，我怕参赛的选手成绩太低了。高点我还好一点，自欺欺人一下说，哎呀好高，自己去了也拿不了冠军，要是低了，自己没去，失去冠军机会，心里痛啊。后来结果出来，也不怎么高，心里真难受。”
人教版高中语文必修3《善待生命 学习论证》教案2篇
论证方法之引证法如何用好引证法：1.所引用的名言警句等针对性要强。每句名言都产生于特定的背景，都应用于特定的交际目的，即使谈同一个问题，也有不少名言可供选取。2.要简洁，不宜过多。议论是在发表自己的见解而不是在介绍他人的见解。引用他人的话，目的是为了让读者更加信服自己的话。3.要注意直接引用和间接引用的区别。直接引用务求文字、甚至标点均准确无误；间接引用只须述其大意，但要注意人称的转换。论证方法之喻证法喻证法是用设喻来论证论点的方法。在议论文中，设喻可以使论点更易懂、更风趣、更容易获得读者的认同。喻证法能化抽象为具体、化艰深为浅显、化枯燥为生动。论证方法之喻证法如何用好喻证法：1.以小见大，就近取譬。要精选生活中细小的、人们熟悉的事物做为设喻的喻体。2.喻体不求形似，只求神似。做为喻证的喻体与做为比喻的喻体不同。比喻的喻体是为了强调特征，描绘事物，侧重形似，以形比形；而喻证的喻体是为了阐发观点，以正视听，力求神似，以义取形。
人教版高中政治必修4生活处处有哲学精品教案
（三）合作探究、精讲点拨。探究一：探究问题：如何看待排名一名高中生在谈到“排名的二重性”时说：“我们既不能盲目地张扬排名，也不能简单地否定排名。作为学生，如果用片面的观点对待排名，排在前面沾沾自喜、骄傲自满，排在后面灰心丧气、一蹶不振，就会停滞不前，甚至倒退；如果通过排名了解自己的学习实力以及同别人的差距，做到知彼知己，扬长避短，就会出现先进更先进、后进赶先进的生动局面。”问题：(1)在排名问题上，人们的看法往往各不相同，这是为什么?(2)为什么我们应看到排名的“二重性”?(3)联系生活中类似的事例，谈谈生活与哲学的关系。教师活动：指导学生阅读以上的材料，并思考所提问题。学生活动：阅读材料，分组讨论问题，发表自己的观点，分析材料中包含的哲学道理。教师点评：(1)在排名问题上，人们的看法不同，主要是因为人们的思维方法不同。

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.
