人教A版高中数学必修二直线与平面垂直教学设计
1.观察（1）如图，在阳光下观察直立于地面的旗杆AB及它在地面影子BC,旗杆所在直线与影子所在直线的位置关系是什么？（2）随着时间的变化，影子BC的位置在不断的变化，旗杆所在直线AB与其影子B’C’所在直线是否保持垂直？经观察我们知道AB与BC永远垂直，也就是AB垂直于地面上所有过点B的直线。而不过点B的直线在地面内总是能找到过点B的直线与之平行。因此AB与地面上所有直线均垂直。一般地，如果一条直线与一个平面α内所有直线均垂直，我们就说l垂直α，记作l⊥α。2.定义：①文字叙述：如果直线l与平面α内的所有 直线都垂直，就说直线l与平面α互相垂直，记作l⊥α.直线l叫做平面α的垂线，平面α叫做直线l的垂面．直线与平面垂直时，它们唯一的公共点P叫做交点．②图形语言：如图．画直线l与平面α垂直时，通常把直线画成与表示平面的平行四边形的一边垂直．③符号语言：任意a?α，都有l⊥a?l⊥α.

二是树立问题意识。问题是事物矛盾的直观反映，是实践发展的有力引导，抓住了主要问题，就找到了工作的着力点和突破口。实践中有什么问题，我们在工作中就要研究什么问题，努力解决什么问题。这是最朴实的方法论。比如，关于简化报表的问题。在调查研究中，基层同志反映，工会系统数据库要整合共享，不能都分头管理，多头要数据，重复要数据，还有大量的日常检查填表、统计报表，基层不堪重负，影响队伍力量办实事，“填表不等于工作”，实干才能服务职工。三是注重基层导向。基层是工会全部工作的基础。×市总工会高度重视基层，率先在乡镇街道全部建立总工会，率先明确乡镇街道总工会经费留成×％，率先在乡镇街道全部建立工会服务站，并由市区两级工会分担聘用专职工会社会工作者，有了一支专门的基层工会工作者队伍，保障了基层工会作用发挥。做实基层，夯实基础，工作才能落到实处，工会才能扎根职工群众之中。

初中数学人教版八年级上册《719镶嵌》说课稿
一.关于教学内容和教学要求的认识 本节课是一节探究性活动课，教学大纲上对数学活动课作了这样的解释：“数学活动课指在教师的指导下，通过学生自主活动，以获得直接经验和培养实践能力为主的课程。教育的目的在于弥补数学学科课程的不足，加强实践环节，重视数学思维的训练，培养学生的学习兴趣，促进学生志趣、个性、特长等自主和谐发展， 从而全面提高学生的数学素质”。可见教学大纲把实习和开展探究性教学放在了重要的地位。
初中数学冀教版八年级下册《正方形》说课稿
二、学习新知1.正方形的定义在这一环节中，学生很容易犯的一个错误就是条件重复。这时我会引导学生从画图入手，提示他们：你能不能减少条件画出正方形呢？这一环节中我的观点是正方形的定义不是唯一的。我们可以从不同的角度来总结，只要合理就加以肯定。比如当学生总结出：四个角都是直角，四条边都相等的四边形是正方形。这时可以提醒学生是不是一定要四条边都相等，减少边的条数可以画出来吗？角的个数可以减少吗？鼓励学生动手试一试。通过动手画图可以很容易的得到正方形的一个定义：三个角都是直角，一组邻边都相等的四边形是正方形。通过小组讨论的形式来完成这一环节的设置。鼓励学生利用现有的材料继续构造正方形。从另一个角度总结正方形的定义。

大学教师年度考核个人总结范本参考
一、思想上 一年来，我时时处处不忘加强思想政治学习。严格要求自己，处处做同志们的表率，发挥模范带头作用。一年来，我从不因故请假，迟到，旷工。不怕苦，不怕累，总是以百倍的热情投入到工作之中。 二、工作上 一年来，我服从学校领导的分配，认真完成学校交给的各项工作任务。在教学中，我虚心向老教师请教，认真钻研新大纲、吃透教材，积极开拓教学思路，把一些先进的教学理论、科学的教学方法及先进现代教学手段灵活运用于课堂教学中，努力培养学生的合作交流、自主探究、勇于创新等能力。另外，本人在搞好教学工作的同时，还很注重教学经验的积累。发表教学论文1篇。 在搞好工作的同时，我还不忘与同志们搞好团结，尊敬领导及同事，真诚的对待每一位同志。 在这一年的工作中，我得到了学校领导，教师们及学生们的好评。但是，检查起来，所存在的缺点毛病也是不少的，还需今后努力改正。主要缺点还有以下几个方面：一是理论知识的学习还是欠缺，还存在有懒惰思想；二是工作虽然很努力，可是个人能力还有待提高，学生成绩进步不是很快。今后，我一定在校领导及全体同志们的帮助下，加强学习，提高工作能力，使自己的思想和工作都能更上一个台阶！

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.

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.

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.
