3. 教学内容分析:

本课是高一必修一的Unit4中的Reading, “A Night The Earth Didn’t Sleep”该课的中心话题是earthquake, 内容主要是地震前兆, 地震危害及震后救援。培养学生获取信息和处理信息的能力。通过略读找到每段的主题句;通过查读掌握细节;通过细读, 理解课文标题的含义, 从而培养阅读理解微技能。

4. 学生情况分析:

教学对象为高中一年级学生。学生愿意主动与他人交流合作、讨论问题, 又有自己独特的见解, 由于高一语文也有一篇有关唐山大地震的文章, 为此学生对内容不陌生。但本班学生英语颇差, 布置的任务要照顾到不同层次的学生, 让他们觉得有成就感, 能建立起学习英语的兴趣和信心。

二、教学目标

1. 知识与能力:

本课为阅读课型, 介绍唐山大地震的前兆, 地震危害及震后的援救。通过观看唐山大地震的相关视频在视觉上给予学生极大地震撼, 有身临其境之感, 深切感受到地震前所发生的一系列的异常现象, 地震发生后对整个城市造成的毁灭性的破坏, 以及随之而来的全国军民大救援等。从不同角度设计目的明确的任务, 展开课堂教学活动, 比如 (1) 针对震前, 都出现了什么前兆; (2) 在震中都造成什么样的破坏; (3) 震后人们怎样面对。

2. 方法与途径:

(1) 通过上网搜索, 了解唐山大地震的情况, 培养学生获取信息和处理信息的能力。

(2) 让学生进一步学习使用恰当的阅读方法与技能。阅读理解微技能的培养。着重培养略读 (skimming) , 查读 (scanning) , 归纳总结内容的能力 (summarizing) , 和猜测词义的能力 (word guessing skills) 等阅读技巧。

(3) 语篇重建:在正确理解课文的基础上, 能用课文中的语言知识, 设计一次对唐山大震幸存者的访谈。

3. 情感目标:

通过了解唐山大地震前兆, 培养学生对自然灾害的应对意识和能力;通过灾后重建, 使学生树立战胜自然灾害的信心。在问题解决和完成学习任务过程中激发学生自主探究的兴趣和热情。

三、教学重点和难点

1. 了解有关地震的细节问题。

比如找出震前出现的现象, 地震时带来的毁灭性破坏, 找出具体的数字和形象生动的动词, 形容词对地震的描述以及震后大救援时都是怎样做的。

2. 提高阅读技能和运用英语进行思维、推理和判断的能力, 提高学生的阅读能力和综合运用语言的能力。

根据地震的视频, 文章, 图片和FLASH动画等形象地给学生提供了素材, 通过用本课的词汇和句子表达图片的内容, 以及采访和讨论震前, 震中, 震后的人和事以及体会。

3. 培养日常对自然现象的观察能力和思考能力, 对地震中逃生和救生的了解。

特别是通过Flash动画形象的展示了我们在不同场合的逃生办法。

四、教学准备

印发了本课的导学案以及在为讨论震中时设计的表, 有关数据和动词形容词描述地震所造成的破坏。在网上下载节选了有关唐山大地震的视频。下载了有关地震逃生的Flash动画。

五、教学过程

StepⅠCheck the guidance case

StepⅡ1.Lead in.Appreciate the poem about an earthquake.Please guess who am I.由一首关于地震的诗导入本课唐山大地震, “A Night The Earth Didn’t Sleep”对此题目提问, What’s the meaning about this title?

StepⅢReading

StepⅣSummarize the structure of the passage.

StepⅤInterview

StepⅥThrough the FLASH

StepⅦHomework

Make a speech about how to find a safe place in different situation.

六、教学反思

高一英语必修1答案 第4篇

【关键词】有效教学;实践;反思

新课程标准指出,学生的数学学习内容应该是现实的、有意义的、富有挑战性的,在教学过程中,我采用了“问题情景——建立模型——探究——解释——应用——拓展”的模式展开,也就是说,在课堂教学中,尽力做到教材的内容尽量与现实生活中问题相挂钩,让学生感觉到数学就在身边,显示数学的实用性。这方面,人教A版已经做出了很好的示范。教材编写了很多实例,如集合的含义与表示,一开始就以实例入手,引出元素和集合的含义,而有效教学的理念要求教师在教学中,体现自己的个性,才能促进学生的个性形成和发展。以下是本人教学实践的个案

一、抽象的教学内容与直观化、通俗化、具体化教学之间的关系的反思

案例一:“函数单调性”,由f(x)=x2的图象观察y随x变化情况。

函数的单调性,教材编写的很好,从图形语言——文字语言——数学语言,一步一个台阶,可在实施过程中,我先让学生自己探究后,犯错、徘徊后才提醒,教学过程中发现,文字语言:“当x>0时,y随x的增大而增大”,学生在初中里用过,一下就能说出来,而最后一个台阶,学生却很难跨上,即数学语言:“当0f(2-x)的解集。我把f(x)和x比喻成戴帽的人与没戴帽的人,两个人比高,要相同条件,要么都不戴帽,要么同时戴帽,增函数可理解为一般的普通的帽子,高个子戴着仍然是高个,矮个子戴着仍然是矮个子,减函数可理解为魔术帽,矮个子戴了变高,高个子戴了变矮。

因此,数学教学中问题的设计和选择,应尽可能地来源于学生们的实际生活经历,应找出更多的机会让学生们接触各种各样的现实问题,捕捉学生的生活的疑点、兴奋点,社会生活和热点,同时使抽象的教学内容更直观、更通俗、更具体。

二、堂上合作探究学习的时间与自主技能训练的时间之间的关系的反思

也就是说,要合理分配两者的时间。一节课中,如果教师为了让学生多点的时间进行笔头练习,自己过早地抛出题设结论和过程,就会使学生失去探究学习和求知的兴趣,这与新课标的精神不相符。但数学科有它自己的特点,它强调的是培养学生的逻辑思维能力、推理论证能力、空间想象能力和解决问题的能力,而这些能力的形成需要有牢固的知识技能作基础。

案例二:在研究几类不同增长的函数模型时,我讲完课本的例1后,就让学生自己去探究y=2x,y=2x,y=x2,y=log2x在(0,+∞)的增长情况进行比较,让学生找出关键点,找出交点,在课内的探究,时间有限,数字运算不可能太复杂。新课程提出要赋予学生更多自主活动、实践活动、亲身体验的机会,以丰富学生的直接经验和感性认识,宗旨在引导学生通过动口、动手与动脑,在亲自体验过程中获得发展,而一节课的时间很有限,处理好探究学习的时间与自主技能训练的时间之间的关系,是提高上课效率的关键。

三、学生实际水平与新的教学内容之间的关系的反思

新课程标准指出,学生的个体差异表现为认知方式与思维策略的不同,以及认知水平和学习能力的差异。我充分利用教材,同时也大胆地整合教材,使我的课堂教学更适合我的学生。

案例三:“函数”,初中到高中,初中的函数,教材采用“变量说”,高中提出了“对应说”,人教A版采用了从实际例子中抽象概括出用集合与对应的语言,定义函数的方式介绍函数概念,把“映射”作为“函数”的一种推广,这种安排我在实践中觉得更有利于学生集中精力理解函数的概念。而具体教学过程,我为学生设计他们熟悉的“行程问题”、“比例问题”、“价格问题”,利用图表、图形(如课本第26页的练习2),让学生探究用集合与对应的语言来刻画,从学生熟悉实际背景和定义两个方面,帮助学生理解函数的本质。要求学生认识、描绘以及概括模式。

到了第三章,函数的应用,尽量挖掘与其它学科的联系以及实际生活的联系,如电话费、水电费、出租车费与用时的关系,银行利息与存款时间的关系,保险、物价、抽奖、股票、债券等等。引导和组织学生以学习小组的形式,进行调查和研究,让学生经历丰富的情感体验和实践活动,在情境中展开想象的翅膀,充分发挥思维的潜能,在生活中发现数学,提炼数学,应用数学。

总之,在教学反思的行动中,我坚持:一是保持敏感而好奇的心灵,“好奇心‘唤起关心’,唤起对现在存在或可能存在的东西的关心。正是好奇心使人们摈弃熟悉的思维方式,用一种不同的方式來看待同一事物。二是要经常、反复地进行反思,通过反思来理解对象、理解自己,让自己与对象对话、与自己对话

高一数学必修1习题及答案 第5篇

1.下列各组对象能构成集合的有()

①美丽的小鸟;②不超过10的非负整数;③立方接近零的正数;④高一年级视力比较好的同学

A.1个B.2个

C.3个D.4个

【解析】①③中“美丽”“接近零”的范畴太广,标准不明确,因此不能构成集合;②中不超过10的非负整数有:0,1,2,3,4,5,6,7,8,9,10共十一个数,是确定的,故能够构成集合;④中“比较好”,没有明确的界限,不满足元素的确定性,故不能构成集合.

【答案】A

2.小于2的自然数集用列举法可以表示为()

A.{0,1,2}B.{1}

C.{0,1}D.{1,2}

【解析】小于2的自然数为0,1,应选C.

【答案】C

3.下列各组集合,表示相等集合的是()

①M={(3,2)},N={(2,3)};②M={3,2},N={2,3};③M={(1,2)},N={1,2}.

A.①B.②

C.③D.以上都不对

【解析】①中M中表示点(3,2),N中表示点(2,3),②中由元素的无序性知是相等集合,③中M表示一个元素:点(1,2),N中表示两个元素分别为1,2.

【答案】B

4.集合A中含有三个元素2,4,6,若a∈A,则6-a∈A,那么a为()

A.2B.2或4

C.4D.0

【解析】若a=2,则6-a=6-2=4∈A,符合要求;

若a=4,则6-a=6-4=2∈A,符合要求;

若a=6,则6-a=6-6=0?A,不符合要求.

∴a=2或a=4.

【答案】B

5.(2013?曲靖高一检测)已知集合M中含有3个元素;0,x2,-x,则x满足的条件是()

A.x≠0B.x≠-1

C.x≠0且x≠-1D.x≠0且x≠1

【解析】由x2≠0,x2≠-x,-x≠0,解得x≠0且x≠-1.

【答案】C

二、填空题

6.用符号“∈”或“?”填空

(1)22________R,22________{x|x<7};

(2)3________{x|x=n2+1,n∈N+};

(3)(1,1)________{y|y=x2};

(1,1)________{(x,y)|y=x2}.

【解析】(1)22∈R,而22=8>7,

∴22?{x|x<7}.

(2)∵n2+1=3,

∴n=±2?N+,

∴3?{x|x=n2+1,n∈N+}.

(3)(1,1)是一个有序实数对,在坐标平面上表示一个点,而{y|y=x2}表示二次函数函数值构成的集合,

故(1,1)?{y|y=x2}.

集合{(x,y)|y=x2}表示抛物线y=x2上的点构成的集合(点集),且满足y=x2,

∴(1,1)∈{(x,y)|y=x2}.

【答案】(1)∈?(2)?(3)?∈

7.已知集合C={x|63-x∈Z,x∈N_},用列举法表示C=________.

【解析】由题意知3-x=±1,±2,±3,±6,

∴x=0,-3,1,2,4,5,6,9.

又∵x∈N_,

∴C={1,2,4,5,6,9}.

【答案】{1,2,4,5,6,9}

8.已知集合A={-2,4,x2-x},若6∈A,则x=________.

【解析】由于6∈A,所以x2-x=6,即x2-x-6=0,解得x=-2或x=3.

【答案】-2或3

三、解答题

9.选择适当的方法表示下列集合:

(1)绝对值不大于3的整数组成的集合;

(2)方程(3x-5)(x+2)=0的实数解组成的集合;

(3)一次函数y=x+6图像上所有点组成的集合.

【解】(1)绝对值不大于3的整数是-3,-2,-1,0,1,2,3,共有7个元素,用列举法表示为{-3,-2,-1,0,1,2,3};

(2)方程(3x-5)(x+2)=0的实数解仅有两个,分别是53,-2,用列举法表示为{53,-2};

(3)一次函数y=x+6图像上有无数个点,用描述法表示为{(x,y)|y=x+6}.

10.已知集合A中含有a-2,2a2+5a,3三个元素,且-3∈A,求a的值.

【解】由-3∈A,得a-2=-3或2a2+5a=-3.

(1)若a-2=-3,则a=-1,

当a=-1时,2a2+5a=-3,

∴a=-1不符合题意.

(2)若2a2+5a=-3,则a=-1或-32.

当a=-32时,a-2=-72,符合题意;

当a=-1时,由(1)知,不符合题意.

综上可知,实数a的值为-32.

11.已知数集A满足条件:若a∈A,则11-a∈A(a≠1),如果a=2,试求出A中的所有元素.

【解】∵2∈A,由题意可知,11-2=-1∈A;

由-1∈A可知,11-?-1?=12∈A;

由12∈A可知,11-12=2∈A.
