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

我今天说课的内容是选自幼儿园建构式课程中班下册科学教育活动《我爱大树和小花》。《新纲要》科学领域目标中明确提出了：培养幼儿爱护动植物，关心周围环境，亲近大自然，珍惜自然资源，有初步的环保意识。在我们生活的周围有各种各样的树和花，对于孩子来说既熟悉又陌生，每每在户外活动时孩子总会不经意地去看看、摸摸，有时还会说一句，如：这颗树好大哦，这朵花好漂亮哦，有时候还会进行追问，如：这颗叫什么树，这叫什么花……然而随着社会的进步人类慢慢淡化了对身边花草树木的爱护，甚至亲手破坏身边的环境，如：乱砍树木，乱摘花朵……结合中班建构式课程中的主题教学《大树和小花》的内容，我设计了符合中班幼儿年龄特点的教学活动《我爱大树和小花》，引导幼儿要保护身边的花草树木，清楚花草树木与人类的关系以及对人类的作用。通过挂图与教材的阅读理解保护花草树木的重要性，从而萌发幼儿爱护花草树木的情感。

幼儿园中班音乐说课稿 夏天到
新的《幼儿园教育纲要》指出：“教师应成为幼儿学习活动的支持者、合作者、引导者”。活动中应力求形成合作探究式的师生互动、生生互动。因此，活动中除了以积极饱满的情绪影响孩子外，我精选了以下几种教学方法：1．根据幼儿的具体形象思维占主要地位的特点和幼儿语言发展的特点，我采用视听唱法，引导幼儿在观察生动形象的图片，充分地刺激幼儿的视觉，用语言和音乐熏陶帮助他们轻松地理解歌曲内容，熟悉歌曲旋律。2．根据“先行组织者理论”，采用难点前置的方法，引导幼儿感知歌曲的强弱节奏，并分段学唱。从幼儿熟悉的雷声、蛙声入手，引导幼儿感受三拍子的强弱节奏，同时熟悉歌曲旋律，学唱歌曲。3．根据幼儿活泼好动的年龄特点，采用游戏对唱的方式，引导幼儿倾听同伴的歌声，学习协调一致地进行演唱。教学活动是老师和幼儿共同表演的舞台，而幼儿是学习活动的主体，教师的“表演”以及活动中所呈现的一切都必须为孩子自然的学习服务。因此，我在本次活动中注重幼儿自身的学习和体验，采用体验学习法和多种感官参与法，引导幼儿在体验中学习，通过想一想、说一说、看一看、听一听、学一学、唱一唱等多种感官的活动，学习演唱歌曲。
