4.4年级下英语2单元教案 篇四
一、本节内容涉及的主题
本节包括<<细胞的分裂与分化>>、<<多细胞生物体的组成>>、<<单细胞生物>>三节内容。<<细胞的分裂与分化>>介绍了使用显微镜观察洋葱根尖细胞分裂的基本过程,描述了生物的生长现象,细胞的分化现象及组织的概念和类型。
本节内容能使学生理解生物体为什么能够由小长大。不同的组织如何形成,植物和人体的不同组织怎样识别等。本章关于器官、系统的知识是细胞和组织知识的深化和发展。生物体的基本单位细胞在构成生物体时,首先构成组织,然后由组织形成器官及系统。学生只有先了解细胞分裂的基本过程和细胞的生长现象,才能进而理解组织的概念。
本节关于多细胞生物生命活动的协调统一和单细胞生物的形态结构和生命活动特点的知识,是学生解释生物体生命活动特征的基础。本节内容的学习还将为学生学习生物体各种结构与功能。生物与环境的关系等知识打下基础。
二、复习目标
1、说出细胞分裂的基本过程;
2、描述生物的生长现象与细胞数目增多,体积增大有关。
3、描述动植物细胞的分化过程以及通过分化形成组织的过程。
4、识别植物体的主要组织和人体的基本组织。
5、描述多细胞植物体的结构层次:细胞、组织、器官、个体。
213、器官是怎么构成的?系统又是什么?、14、不同的组织按照一定的次序组合起来,形成具有一定功能的结构,叫做器官。
15、一株完整绿色开花植物体的器官组成:根、茎、叶、花、果实、种子。
16、绿色开花植物的这些器官分别起什么作用呢?(根的主要作用是能在土壤中不停地吸收水分和无机盐。)(叶伸展在空中,能够接受阳光照射,制造出有机物来。)(茎能把根和叶连接起来,并输送他们体内的物质。)(有了花才能形成果实。)
17、绿色开花植物的结构层次:细胞—组织—器官—个体。
18、与人体消化有关的器官有哪些?这些器官共同具有的生理功能是什么?人体是否与植物一样由器官就能直接构成个体?
19、由于人体器官的增加,生理功能的复杂,故不能像植物那样直接由器官构成人体,而形成了又一结构层次——系统。
20、人体器官的构成是否和植物相同呢?(人体的器官也由多种组织结构)。
21、人体的结构层次是怎样的呢?(细胞—组织—器官—系统—人体)。
22、两种情景:
1、坐在椅子上休息;

(4)评出合格导游。得到规定分值即为合格导游。

7.4年级下英语2单元教案 篇七
探索发现事物中稍复杂的排列规律。教材安排了两个数学活动。首先教材选择了有规律、不断闪烁的交通信号灯作为数学活动的素材。首先通过让学生说一说交通信号灯的闪烁情况,发现规律,同时了解信号灯表示的含义。活动二,通过呈现了5组有规律摆放的图形和数列,让学生找规律。
教 学 目 标
能发现给定事物中的隐含规律,能自己确定简单的排列规律。
通过观察推理等活动经历发现事物中有规律的现象的过程。
感受数学与生活的联系,培养数学应用意识。
教学重点与难点 探索发现事物中稍复杂的排列规律。
器材、课件准备 课件、教学图片
探索发现事物中稍复杂的排列规律
颜色信号灯的含义: ①红灯停。②绿灯行。③黄灯缓冲。
信号灯闪烁的规律: ①绿黄红 ②绿红黄 ③红……
创设故事情境,激发学生参与学习活动的兴趣。通过让学生自己观察、推理,发现给定事物中隐含的规律,采取灵活多样的教学方式,让学生通过仔细观察、动手操作,能发现并能按规律排列事物。感受数学与生活的联系。课堂效果很好。
教学 设 计
教 师 活 动 学 生 活 动 说 明
一、创设情境、激发兴趣
故事引入:大头娃要到少年宫参加数学竞赛,一路上,他边开车边想:我怎样才能在数学竞赛中取得好成绩呢?想着想着,一不小心闯进了红灯区,兔警察拦住了他,很严肃的问他:“你知道这几种颜色的信号灯代表什么意思吗?”
二、体验、感悟、探究
1、出示交通信号灯图片。师:同学们想大头娃会怎样回答?引导学生根据自己的经验说一说各种交通信号灯的含义。
学生联系自己的生活实际说各种颜色信号灯的含义。
①红灯停。②绿灯行。③黄灯缓冲。
大头娃和你们一样聪明,很快回答了兔警察的问题,兔警察放他继续上路了。
2、引导学生回忆、观察、回答三种信号灯是怎样闪烁的有什么规律吗?
学生结合自己的经验说信号灯闪烁的规律。
①绿黄红 ②绿红黄 ③红……
3、师演示信号灯的规律。认真观察、感悟规律,说一说正确的闪烁规律。
4、出示“说一说”题目
问:下一个该亮什么颜色的信号灯?
大头娃到了少年宫遇到了四个竞赛题目,让我们和大头娃一起参加数学竞赛好吗?
出示:找规律一题。
先让学生仔细观察,每组有什么规律,然后同桌交流。
仔细观察每组排列的规律,先同桌说一说,然后班上汇报,有不同意见可补充。
三、实践与应用
1、出示第二道竞赛题(即练一练第一题)
组织学生独立完成后订正。
①学生观察后独立贴图片。
②订正。
学生边说边演示。
2、出示第三道竞赛题(即练一练第二题)
师:猜一猜带“?”的图形应是什么颜色,并说一说你的理由,猜对了奖一颗智慧星。
①观察后猜测,说出自己的理由。 ②学生独立涂色。
3、出示第三题
要求学生自己确定规律,然后按自己确定的规律涂色。
学生观察后确定规律,然后独立按自己确定的规律涂色。
组织学生充分交流,展示自己的成果。
学生到前演示自己的成果,交流自己的想法
四、评价交流、体验成功。和同桌互相说一下,这节课你又学到了哪些知识?
小结。
8.4年级下英语2单元教案 篇八
Unit 2 The apples are falling down the stairs.教材分析
语言功能:用英语寻求帮助。描述某人正在做什么事。
语言结构:
Who can help me?
The apples are falling down the stairs.教学目标:
a.语言知识目标:
学习目标语句Who can help me?
The apples are falling down the stairs.b.语言技能目标:能够听懂会说本模块句型,能运用所学语言进行询问及描述。
c.情感态度目标:激发学生学习英语的兴趣及运用英语交流的热情,使学生在学习中建立自信,提高学生参与语言活动的积极性。
教学重、难点:
重点:Who can help me?
The apples are falling down the stairs并能在实际情景中运用。
难点:stairs的发音。
学生分析
学生在 unit1中已经初步地学习了向别人寻求帮助的句型,有了一定的基础,因此在本课的学习中,他们需要更多的活动来参与,来实践,来运用他们所学的语言。而且六年级的学生仍然以形象思维为主,教学应尽量采取形象、生动、活泼、有趣的活动来激发他们的学习兴趣,树立他们的自信,从而使他们真正成为学习的主人。
设计理念
在本课的设计中,教师以学生为主体,采用多种教学形式,并与信息技术相整合,设计贴近学生实际的教学活动,培养了学生的综合语言运用能力。
教学准备
教学挂图单词卡片、录音机、CAI课件
教学过程
Ⅰ.Warm-up(热身活动)
教师可以带领学生一边唱“the sun is shinning”,一边做动作。
(课前齐唱节奏欢快的英语歌曲,既调节情绪、活跃气氛,又使学生快速进入英语学习状态,并激活学生已有的知识,为进行新课教学做好铺垫。)
Ⅱ.Presentation(介绍新语言项目)
教师对学生说:“今天的课文里,描述的是一个女孩的情况,让我们一起去看看,她在做什么?”
Ⅲ.New teaching(课文教学)
a.教师在黑板上贴出挂图,用录音呈现课文的内容,请学生听发生了什么事情。听完第一遍录音后,老师可以提出一些带ing的单词,让学生带着问题听第二遍,如:“What is the girl doing?”
b.听完第二遍录音后,老师可以试着让学生提一些问题。如:“What’s the matter?’停第三遍录音时。学生可以边听边跟读,把课文中带有ing的单词划出来,并找出大家问题的答案。c.放录音听活动3的歌曲,一起学唱。
通过听录音,让学生清楚今天要学的语言知识是在什么样的语境下进行的。并且给出一个问题,让学生带着问题有目的地听,做到有的放矢。并让学生了解到东西方对女士称呼的差异以及背后所隐含的不同的文化意识。
Ⅳ.Practice(练习)
a.同桌一组进行问答练习,完成SBU1A3。教师在教室内巡回走动,给予适当的帮助与指导。b.小队进行“开火车”问候游戏,比一比哪个小队说得好,说得快.最后请两个优秀小队上前展示,由老师给予奖励。
c.播放CAI课件。大屏幕上显示几种场景,同桌之间编对话。
本环节通过机械操练让学生理解语言,掌握语言。角色扮演则给学生创造了一个仿真的情境,强化了所学语言。这个小练习放在操练阶段有助于缓解学生的疲劳,保持高涨的热情。
Ⅴ.Production(任务完成)
a.完成课堂活动用书练习1。首先为学生讲解题目要求,请学生阅读练习内容,试着预测答案。然后请学生认真听录音,试着理解。再放录音,请学生连线,最后全班订正。b.完成课堂活动用书练习3。学生先观察图片,然后听音跟读,理解。连线。
在完成任务的过程中,学生们充分运用了他们所学的语言,达到了学以致用的目的,提高了实际语言运用的能力,而且激发了他们的兴趣,增强了他们的合作意识,为日后更好地学习英语树立了信心。
Ⅵ.Summary and Homework(小结与作业)
9.4年级下英语2单元教案 篇九
教学目标::
1.会认14个生字,会写9个字。
2.有感情地朗读课文,重点读好笋芽儿和春雨姑娘等人物的对话,感受笋芽儿对美好春光的向往和奋发向上的精神,体验投身大自然的情趣。
3.爱读科学童话故事,能从童话故事中吸取力量,陶冶情操。
教学重点:
识记生字,读好不同角色的语气,体会童话中蕴涵的意义。
信息资料:
生字卡片;笋芽儿、竹子的音像资料或图片;投影仪。
课时安排:两课时
第一课时
一、谜语导入
“小时层层包,大时节节高,初生当菜吃,长大成材料”。猜猜看这是什么?(笋)见过吗?(出示笋的图片)小笋芽是怎样长成一株健壮的竹子的?板书课题,提醒学生“笋芽儿”的读法。
二、自学
标(标出自然段的序号)
划(边读边划出不认识的字词,想办法记住它们)
读(读准字音,读通课文)
想(自己读懂了什么?还有什么不懂的?)
查(同桌互相检查自学情况,教师巡视指导)
三、交流
1、正音:小老师领读—开火车读—按偏旁归类读—扩词读—同桌互考,全读对的同桌奖励一颗小笋。
2、展示方法
如:猜谜:两辆车——轰;尹戴竹帽——笋
动作演示:唤/揉/扭/钻/抚/辫
3、读文:指名分段读课文,注意读准字音。
4、质疑:自学中有哪些不懂的问题?
四、感悟
1、读一读春雨姑娘和雷公公呼唤笋芽的段落,想象他们呼唤的语气一样吗?
2、重点指导春雨和雷公公呼唤的语气。
(1)春雨姑娘是怎样呼唤笋芽的?(声音柔和、语气亲切,有“润物无声”的感觉)谁能试着“低声呼唤”笋芽儿?
范读——指名读——评读———练读——齐读。
(2)谁来做雷公公呼唤沉睡的笋芽儿?他和春雨姑娘的语气一样吗?(声音粗重,带有鼓励)
练读——挑战读——分组读——齐读。
(3)笋芽儿苏醒时什么样?通过做动作、联系已有的生活经验理解“揉”“伸”撒娇”“扭”“一个劲地”“钻”“等词语。
模仿读——加动作表情表演读——男女声竞赛读——评读——自愿展示读。
(4)分角色表演读课文前四自然段。
五、学习写字
1、练习书写“喊、呼唤、笋芽”五个字。教师重点指导写口字旁的字:“口”字位置要偏上,不宜写得太大。三个带口字旁的字中,“唤”是新认识的字,可以重点指导,右边第六笔“撇”,要上下贯通,不能写成竖、撇。
2、学生练习书写,互相评价打等级。第二课时
一、复习
1、把自己积累的好词佳句读给大家听。
2、分组竞赛读文。
二、朗读
1、轻声读课文:笋芽儿钻出地面时看到春天的景色是什么样的?
2、你能读出春天的美景吗?(指名读、齐读)师生共同感悟春光的美好。
3、仿句训练:笋芽儿还看到了什么?你还能像书上那样说几句吗?
三、想象
1、默读课文:假如你现在就是这株健壮的竹子,你最想说什么?(可以对春雨姑娘说,也可以对雷公公说„„)
2、再读感悟:你喜欢笋芽儿吗?为什么?启发学生由竹子的成长联想到自己的成长:你们在成长过程中得到了哪些关心和爱护呢?
四、表演
1、以小组为单位排演课本剧,教师巡视指导。
2、班级推选表演好的小组,戴头饰进行角色表演。
五、写字
1、学习写“冈、世界、轰”四个字。教师重点指导“冈”字的横折钩的折笔要垂直,不可向内收;里边的“”不能太小,第二笔是长点。“轰”字左边的“又”字捺要变成点。
2、学生练习书写,组内互相评价。根据同学的建议,把自己写不好的字再写几个,直到自己满意为止。
3、全班交流展示,评选“小小书法家”。
