    人教版新课标小学数学一年级上册8、7、6加几 说课稿2篇

    《8、7、6加几》一课是人教版义务教育课程标准实验教科书·数学·一年级上册P103-104中的内容,本节课是在学生学习和掌握了9加几的基础进行的,计算加法的方法与上节相同。学生对用“凑十法”解决问题已有了初步的认识,因此本节课主要通过让学生动手操作、比较,实现知识的迁移过程。同时,本节内容还兼有巩固上节教材的任务。教材中安排了三个例题。《数学课程标准》指出“数学教学必须注意从学生熟悉的生活情境和感兴趣的事物出发,使孩子们有更多机会从周围熟悉的事物中学习数学、理解数学,让学生感受到数学就在他们的周围。”因此,本节课我创设了一个带领同学去游乐园的情境,引导学生在情境中观察、操作、交流,使学生体验数学与日常生活的密切联系,感受数学在生活中的作用;加深对数学的理解,并运用数学知识解决现实问题。

    教材分析义务教育课程标准实验教科书数学(人教版)一年级上册,把8和9的认识放在同一节课中完成,编排与前面6和7的认识基本上一样,只是要求更高。教材中提供给学生数数的资源虽不如6和7明显,却更丰富。提供给学生数数的对象是以“热爱自然,保护环境”为主题的生动画面,其内容有人、花、树、花盆、蝴蝶、黑板上的字等。画面除数数外,还体现了环保教育的主题。8和9的序数意义仍是采取6和7的编排方法,不同的是让学生更具体地感受几和第几的意义的不同。学生分析班上学生对数学学习的兴趣浓厚,敢想、敢说、敢问,思维活跃。低年级学生好奇心强,渴望动手参与的愿望强烈,为了让学生主动参与到学习过程中来,我根据一年级学生的心理特点,在学习6和7的认识时,我就尝试让学生课前收集了一些生活中的6和7,并制成剪贴图。没想到学生的信息量还挺大,制成的剪贴图也很生动、活泼。但在认识6和7的序数意义时,有一些不足,有一部分学生对几和第几的概念还有些模糊。

    When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning.

    Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

    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.

After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively.

    通过写文章梗概,培养学生综合运用语言的能力,学习用恰当的英语描述科学家的故事。这是本课的教学难点。教师可以使用完形填空的方式来帮助学生整理语篇,从而来降低难度。本课的教学重点的突破方法是:在阅读前,让学生初步了解得出科学观点所需要的基本程序,从而轻松而自然地导入文章的阅读;在阅读过程中,由易到难设计快速阅读和精读的问题,层层推进各种阅读活动,让学生对阅读内容从整体感知到细节理解,最后深层读懂整篇文章,同时加强阅读策略的指导,让每个学生都主动参与课堂教学活动,最终达到提高阅读能力的目的。Step 4 Post-readingGroup Activities四人小组共同合作,在老师的适当指导下,就以下2个问题展开讨论,让学生就所知、所学、所感和所想融入话题,然后抽若干同学代表作小组发言。1.
