人教版高中地理选修2东北地区农林基地建设的地理背景教案

  • 综合教案有用的报纸

    综合教案有用的报纸

    一次,我有意将废旧报纸投放于晨间桌面、体育区、语言区、表演区等各区域活动,惊奇的发现,晨间桌面他们会用它来折飞机呀、撕碎片呀、团纸球呀,语言区、表演区他们会像真有回事儿似的学爸爸、奶奶看报呀……在成人眼中不起眼的废旧报纸真的成了孩子们的宝贝。经过多次仔细观察,我发现孩子们虽然兴趣浓厚,可对报纸的玩法、利用性还是存在着局限性。新《纲要》中指出:幼儿是教育活动的积极参与者而非被动接受者,活动内容必须与幼儿兴趣、需要及接受能力相吻合。我想,作为教师,应根据幼儿的兴趣、需要和原有经验,引导幼儿走向最近发展区。由此产生了中班综合活动——《有用的报纸》。开展这一活动,孩子们要有一定的基础。我班幼儿已有折、剪、团等用废旧报纸制作的经验。这一活动适合于中班下学期的小朋友。活动设计:一、活动目标1、帮助幼儿理解故事内容,增强爱惜报纸、保护环境的意识2、了解废旧报纸的再可利用性,能想方设法利用废旧报纸,对报纸制作产生兴趣二、重点、难点1、故事内容以及对故事中报纸不同情绪的感知2、想方设法再利用废旧报纸及用旧报纸制作三、活动准备1、事先排练四位大班幼儿担任小小模特儿的角色(身穿报纸服装、头戴报纸头饰,手拿报纸道具,如:纸伞、纸球、纸棒、纸辫子等随乐表演)2、废旧报纸许多,剪刀、胶水、水彩笔、旧图书、白纸、蜡笔、蛋、脏皮鞋等3、轻音乐、故事录音(见后)4、多媒体课件5、事先排练好二段情境表演四、活动过程1、幼儿观看模特儿表演,初步感知旧报纸的用途师:哎呀!小朋友们快看,来了一群小小模特儿,她们身上的衣服多有趣呀!(幼儿观看表演,模特定格)提问:(1)她们身上的衣服是什么做成的呀?(报纸) (2)报纸做的衣服漂亮吗?(漂亮)报纸还做成了些什么呀?(纸球、纸棒、纸辫子、纸伞、纸扇子等)

  • 美术—好大的爸爸课件教案

    美术—好大的爸爸课件教案

    目标:用夸张的手法画出小朋友穿着爸爸衣服的滑稽形象,体现出爸爸高大的形象。准备:爸爸的衣服一件,范画一张、蜡笔、勾线笔若干。过程:一、 出课题。(请一名幼儿穿着爸爸的大毛衣进活动室) XX小朋友今天跟平时有什么不一样?(衣服不是他的,很大) 你穿的是谁的衣服?(爸爸) 你们看,爸爸的衣服穿在小朋友身上是怎么样?(很大、肥肥的) 为什么?(爸爸的个子很高,爸爸身体胖胖的) 二、讲解示范。 你们想不想穿一穿爸爸的衣服,(想)教室里没有爸爸的衣服,我们来画一件爸爸的大衣服。(示范画爸爸的大衣服)我们来穿一穿爸爸的大衣服。(添画上幼儿的头、脚)三、幼儿作画,老师巡回指导。提醒幼儿要把爸爸的衣服画的大大的,显示出爸爸高大的形象。四、结束。让我们穿上爸爸的衣服到外面去。

    2、让幼儿尝试进行版画,掌握版画的基本方法,能初步表现出版画艺术的美。 活动准备: 各色颜料;幼儿绘画毛笔;吹塑纸;铅笔;幼儿自己的花卉日记;等。活动重点: 感受不同材料进行作画的乐趣。活动难点: 掌握版画的基本方法。 设计思路: 随着主题活动《亲亲大自然》的开展,经过了一段时间幼儿对花卉的探索后,幼儿都制作了一本花卉日记本,在对日记本制作的后期做一个怎样的封面让大家开始了思考。在国外,版画是艺术类的必修课,近些年我国各地已有些版画家在为儿童版画教育事业默默地做贡献,这是非常可贵的。同时我受一些大画家版画作品的启发,发现版画的与众不同的美感,何不让我们的幼儿也来尝试尝试,陶冶幼儿的性情,使幼儿感受生活中的美,萌发审美、表现美的情趣呢?于是,我就设计了这次的版画活动。活动流程:情景感知→交流讨论→过程运用

  • 好好玩的蚕豆课件教案

    好好玩的蚕豆课件教案

    2.能积极参与多种形式的活动巩固新知识。3.在活动中能细心作业,体验合作学习的快乐。  [活动准备]  蚕豆种子人手6粒;两种难度的作业卡,蜡笔;数卡每人一张;含有6以内分合式的迷宫图两人一张,投影仪一台;事先和幼儿一起种植一些蚕豆。  [活动过程]  一、合作猜豆  过渡语:今天老师带来了一些小蚕豆,想和小朋友一起玩一个猜豆的游戏。  游戏规则:幼儿两人一组,每人从盘子里拿5粒蚕豆,分放在两只手里。一幼儿伸出两只手,请另一幼儿选择一只手,猜里面藏了几粒蚕豆。两人各猜3次,看谁猜得对。  评析:用“猜豆”的游戏开始本次活动,调动了幼儿参与的积极性,还复习了5的组成。两两合作的形式可以培养幼儿的合作能力,互当老师的角色可以激发幼儿的自信心,孩子们学习的兴趣非常浓郁。

  • 勇敢的奥特曼课件教案

    勇敢的奥特曼课件教案

    活动活动前我做了充分的准备:拳击手套人手一套,沙袋,录音机,磁带,奖章,怪兽服装。 俗话说:“兴趣是最好的老师。”幼儿有了兴趣就能主动积极的去学习,高高兴兴的去玩,但不意味着幼儿都要像拳击手那样地动作规范,只是通过活动让幼儿学习一种健身和发泄的方法,减少攻击性行为。游戏开始我请幼儿扮演奥特蔓战士,苦练拳击本领。再加上一些音乐,把幼儿的生理、心里情绪都调动起来了,有跃跃欲试,一显身手的冲动。林林说:“我要用钩拳打怪兽。”铭铭说:“我会用直拳。”说完他们就到沙袋上打了起来。其他小朋友看到他们像拳击手一样练得好时,也以他们为榜样,练的更带劲。活动中我注重幼儿的个体差异,对能力强、动作好的幼儿不仅要求上肢动作到位,进一步要求脚下灵活,移动迅速,对能力差的幼儿,引导他们掌握出拳动作即可。本领练好了,奥特蔓战士要去执行任务了,开车出发。这时由男老师扮演的怪兽出现了,奥特曼战士要用拳击的本领战胜他,打中要害怪兽就发出叫声,规则是:1、怪兽退回老穴,战士必须回来补充能量。

    北师大初中数学八年级上册认识勾股定理2教案

    意图:课后作业设计包括了三个层面:作业1是为了巩固基础知识而设计;作业2是为了扩展学生的知识面;作业3是为了拓广知识,进行课后探究而设计,通过此题可让学生进一步认识勾股定理的前提条件.效果:学生进一步加强对本课知识的理解和掌握.教学设计反思(一)设计理念依据“学生是学习的主体”这一理念,在探索勾股定理的整个过程中,本节课始终采用学生自主探索和与同伴合作交流相结合的方式进行主动学习.教师只在学生遇到困难时,进行引导或组织学生通过讨论来突破难点.(二)突出重点、突破难点的策略为了让学生在学习过程中自我发现勾股定理,本节课首先情景创设激发兴趣,再通过几个探究活动引导学生从探究等腰直角三角形这一特殊情形入手,自然过渡到探究一般直角三角形,学生通过观察图形,计算面积,分析数据,发现直角三角形三边的关系,进而得到勾股定理.

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。
