五、板书:几何概型的概念:设D是一个可度量的区域(例如线段、平面图形、立体图形等).每个基本事件可以视为从区域D内随机地取一点,区域D内的每一点被取到的机会都一样;随机事件A的发生可以视为恰好取到区域D内的某个指定区域d中的点。
这时,事件A发生的概率与d的测度(长度、面积、体积等)成正比。
我们把满足这样条件的概率模型称几何概型.板书:几何概型的概率计算公式:

人教A版高二上册数学几何概型教学计划 篇2
几何概型在概率论中占有相当重要的地位, 是学生在学习了古典概型之后将会接触的又一重要的概率模型, 它将古典概型中等可能事件数量从有限延伸到了无限, 进一步完善了人类对概率模型的认识, 直接影响着人类现实生活和数学本身的发展。
一、人教A版与苏教版教材“几何概型”概念引入的比较研究
概念的引入方式对学生理解数学概念有着先入为主的作用, 学生对一个新的数学概念的认识往往是从回忆相关的具体实例和已经掌握的知识开始的, 对一个概念或命题是否理解, 视其是否能举出适当的正例或反例。两个版本教材都通过实例引出新概念, 但处理方式有所不同, 具体见下表。
首先, 人教A版教材采用了由数学到生活的导入方式, 从已知知识出发, 让学生体会生活中尚存在着一些无法用现有数学知识解决的问题, 进而引出新的数学概念, 这样的设计较能引起认知冲突, 激发学生学习兴趣;苏教版教材直接从相关的生活实例入手, 提出相应的概率计算问题, 新问题与之前学习的古典概型有相同点, 即基本事件的“等可能性”, 却不能用古典概型的方法去解决, 于是很自然地引起了学生的数学思考和探究的欲望。
其次, 由于苏教版的两个实例较之人教A版的实例叙述完整、形象生动、问题指向明确, 所以更容易在学生头脑中留下深刻印象, 有助于学生对“几何概型”知识从联系实际入手形成良好的数学表征;人教A版教材在复习巩固所学知识的基础上, 通过类比和联想, 发现已有知识的不足, 从思辨的角度引出新的思考, 有助于学生构建良好的概率知识结构。
再次, 问题是数学的心脏, 思维总是和问题联系在一起, 苏教版教材融问题和思考于具体实例之中, 在实例呈现之后, 会及时提出相关问题引发学生思考。其中, 有三处以问句形式提出明确问题, 有两处具体的讲解。而人教A版教材偏向讲解, 虽然没有提出明确问题, 但在讲解过程中辅以具体实例, “有理有据”、“娓娓道来”、“环环相扣”, 有利于学生的逻辑思考, 况且“几何概型”的概念本来就比较抽象, 适当的讲解是完全必要的。
最后, 从实例所涉及的数学问题来看, 两个版本教材的实例都是关于可度量的线段与面积, 没有给出可度量的立体图形, 这一点教师在进行教学设计时应该注意。
二、人教A版与苏教版教材“几何概型”概念提出方式的比较研究
在概念的提出环节, 人教A版通过对一个新问题进行探究, 抽象概括出几何概型的定义, 苏教版直接对概念引入环节的现成问题进行分析, 归纳出几何概型的特征, 具体见下表。
首先, 从引例的合理性来看, 人教A版的实例涉及到一个圆盘, 圆盘被等分成若干区域, 求指针指向某几个区域的概率, 而这样的实际背景往往会使人联想到面积, 而不是弧长, 进而产生用面积的测度去解决问题的想法, 与应该用弧长的测度去解决问题的思路正好相反, 这种认识冲突对初学者来说不是太好的, 容易造成概念的泛化;相反, 苏教版的引例比较恰当, 学生理解起来不会有太大难度。所以, 在概念的引入环节, 宜设计一些简单但能体现概念本质的例子, 所谓“小问题反映大道理”。
其次, 从概念的语言表述来看, 人教A版的叙述比较直观化、生活化, 有助于学生的形象理解, 但数学的形式化程度显然不够, 如很少用到概率统计的专业术语和数学语言去表述, 在数学学习过程中, 适当的生活化和直观化可以对学生理解抽象的概念起到一定的辅助作用, 但这种引导如果过度则不利于学生抽象概括能力的培养;相比之下, 苏教版的概念表述则更有数学味, 更加严谨, 如“可度量区域”、“基本事件”、“随机”“机会”“测度”等, 都是经典的数学用语, 每个数学用语都有着耐人寻味的数学背景, 都能引发学生一定的数学思考。在新课改逐渐表现出“去数学化”的极端情况的今天, 我们呼唤着“更有数学味”的教材的出现。
三、人教A版与苏教版教材“几何概型”例题设置的比较研究
例题一般出现在基本概念介绍之后, 好的例题设置, 有助于强化概念的理解, 对概念的应用也有很好的示范作用。“几何概型”概念的学习是为了渗透用“随机模拟”的方法估计概率的思想, 两个版本教材的例题设计及其分析探究过程也在一定程度上体现了新课标的基本要求, 具体见下表。
首先, 例题的探究过程是对几何概型相关概念的具体分析和应用过程, 正确应用概念解决问题的关键在于建立合理的概率模型, 即判断题目所涉及的区域测度是长度、面积还是体积。人教版有一例用到区域长度, 其他三例用到区域面积;苏教版有一例用到区域长度, 两例用到区域面积, 一例用到区域体积。可见, 关于区域面积的几何概型问题比较多一点, 这一点也反映在课后练习中。需要注意的是, 过多地关注其中一种情形 (面积区域) , 会造成对其它情形的忽视。
其次, 两个版本教材在例题讲解上也颇具特色。首先, 人教A版善于从多个角度分析问题, 如前三道例题都用两种方法来解决, 一是利用几何概型的公式, 一是用随机模拟 (动手设计或计算机模拟) 的方法。这样的设计加深了学生对几何概型的认识与深入思考;其次, 人教A版注重引导学生从动手试验的角度解决问题, 如例题中的“思考问题”是:你能用圆盘等设计一种方法模拟实验吗?例题中的“思考问题”是:你能设计一种随机模拟的方法, 近似计算上面事件A发生的概率吗? (包括手工的方法或用计算器、计算机的方法) , 例题中的方法二指出:我们可以做两个带有指针的圆盘, 标上时间, 分别转动两个圆盘, 记下父亲在离开家前得到报纸的次数……
最后, 需要指出的是, 根据笔者的经验, 例题中的设计似乎有一定难度, 如用公式法解决该问题时, 学生对事件A为什么表示成这样的形式很难理解。《数学课程标准 (试验) 解读》指出, 介绍几何概型主要是为了更广泛地满足随机模拟的需要, 但是对几何概型的要求仅限于初步体会几何概型的意义。这样的例题不妨放到课后练习, 供学有余力的学生作为探究活动的材料。相比较而言, 苏教版的例题设置比较容易理解, 能很好地让学生经历问题解决过程, 体会几何概型的基本思想。
四、人教A版与苏教版教材“几何概型”习题设置的比较研究
习题是中学数学课本的重要组成部分, 习题配备得好不好, 直接影响到学生学习质量的高低, 波利亚曾指出:“一个重大的发现可以解决一道重大的题目, 但是在解答任何一道题目的过程中都会有点滴的发现。”可见, 习题在数学学习中具有非常重要的作用。
人教A版与苏教版的习题都是由练习题和习题两部分组成, 练习题紧扣基本概念和例题, 注重知识的巩固和练习, 习题的编排较练习题难度有所增加, 注重探究和创新。以下是两本教材习题数量和结构层次的统计。
首先, 从习题的结构设置来看, 苏教版习题数量明显多于人教版, 且题目设置呈现一定的层次性;从习题性质来看, 人教A版中的题目比较注重基础, 注重对基本概念的简单应用, 因此每道大题往往由若干个性质或难度相近的小题组成。就本节的知识目标来看, 人教A版这样的设计是符合《普通高中数学课程标准 (试验) 》要求的, 即对几何概型的要求仅限于初步体会几何概型的意义, 但由于题目类型比较单一, 较难体现数学的生活价值和文化价值;而苏教版的习题设置具有多样化和层次性的特点, 相同性质的题目不会重复出现, 并且个别题目具有一定的创新性和探究性。
其次, 从题目的背景来看, 人教A版的题目多以实际生活为背景, 如向靶子射飞镖、计算豆子落在不同图案上的概率、红绿灯中的概率问题、船舶停靠中的概率问题等;苏教版的题目背景比较丰富多彩, 有以数学问题为背景的 (共6道) , 如用模拟方法计算曲边图形的面积、计算点落在不同形状几何图形中的概率等, 也有以现实生活和实际应用为背景的题目, 如:在10000km2的海域中有40km2的大陆架储藏着石油。假如在上述海域中任意一点钻探, 钻到油层的概率是多少?
人教A版高二上册数学几何概型教学计划 篇3
对人教课标A版《数学3》的古典概型的教与学来说,新课标的教学理念在于“列举”.古典概型题渗透在教材中的例题、习题,透过现象,本质上有三种题型:“依次不放回取”、“依次放回取”与“同时取”,分别对应于旧课程中排列、分类(步)计数原理与组合等内容.列举的手段有:列“树枝图”,列“点表”与列“数对表”.但人教课标A版《数学3》没有归纳分类,无形中增加了学生列举基本事件的困难.又考虑到在高二选科时希望在“人文,社会”发展的学生就不用再学计数原理与排列组合以及独立事件同时发生的概率等内容,因此建议人教课标A版《数学3》在例题安排上等细微处要细分并体现这三种题型及直观列举方法,以起示范作用,这样做并没有加重学生学业负担,反而降低“文科”生的列举难度.下面就古典概型的三种题型与列举法的具体操作逐一举例说明.
1.1依次不放回取—对应于旧课程中排列组
合的排列例1口袋里装有2个白球和2个黑球,大小形状完全相同,4个人按顺序依次从中摸出一个球,求第二个人摸到白球的概率.
解:如图1,用a,b表示白球,用1,2表示黑球,则所有基本事件是:
图1共有24个基本事件,其中“第二个人摸到白球”的事件A含有12个基本事件,如“树枝图”中加横线部分的事件.因此 P(第二个人摸到白球)=1224=12.
点评:相当于从4个球中依次不放回取4次,列举手段是“树枝图”.

名词性从句介绍
名词性从句包括:主语从句,表语从句,同位语从句,多由连词that, wh-疑问词或由what, whatever等关系代词引导。
⒈ 主语从句
⑴ 主语从句在句子中充当主语
E.g. Why he refused to work with you is still a mystery.
Whatever comes is welcome.
⑵ 主语从句前的that不能省略,仅仅起连接作用,有时候为保持句子平衡,that从句后置,而由it作形式主语。
E.g. That he became a lawyer may have been due to his mother’s influence.
It is not true that he has moved to New York.
⒉ 宾语从句在句子中充当宾语
E.g. I don’t know where the sound came from.
Don’t be satisfied with what you have achieved.
⒊ 当从句放在系动词be, look, remain, seem等后构成表语从句。
E.g. The trouble is that I have lost his address.
It seemed that the night would never end.
⒋ 同位语从句
⑴同位语从句是对与之同位的名词中心词作进一步解释,能接同位语从句的常见名词有: idea, news, fact, problem, belief, opinion, hope, understanding…
⒌ whether与if 在名词性从句中的用法区别
if 一般 指用于引导从句,而whether可引导包括宾语从句在内的其他名词性从句。
⑴连词whether引导主语从句,表语从句时不能用if来替换。
⑵宾语从句中,whether常与or not搭配,也可以说 whether or not, 而不说if or not.
E.g. I don’t care whether or not she will attend the meeting.
⑶whether也可用在介词 后,或带to 不定式前,if or not.
E.g. She doesn’t know whether to get married now or wait.
I haven’t settled the question of whether I’ll go back home.
⑷ 某些动词后面(如discuss)只能用whether, 不用if .
E.g. We discussed whether we should go on climbing.
在句子中做主语的从句叫主语从句,是一种 重要的名词性从句。
⒈由what等连词引导的从句
⒉ 由that 引导的主语从句
⒊ 由whether, if等引导的主语从句,句
首用Whether
⒋ 由whoever. whatever等引导的主语从句
whoever=the person who或anyone who. who 也可以引导主语从句,但只能表示“谁”
Anyone 与the person皆不能引导从句。
⒌ 由it 作形式主语引起的主语 从句
that从句做主语时候,常用it做形式主语,而把that引导的主语从句放到句子后。在下列情况下使用形式主语it,将主语从句放在句尾。
⑴位于是seem,appear,be(im)possible,be a pity,be a wonder,be likely等。
E.g. It seemed certain that this would win the prize.
It appeared that he was right.
⑵在It is known…; It is said…;It is hoped…; It is believed…等句型中。
注意:有时候在“It is necessary(important. suggested等)+that clause”结构中, that从句常用“should+动词原形” 形式来表示虚拟语气, 其中should常可省去.

E.g. A number of students were studying in the reading-room.
⒉ All around the city of Salisbury, as far as twenty-two miles to the west, and six miles south, down to the coast, farmers raise sheep.(此句子中farmers raise sheep是句子的主干,前面均是表示方位, 距离的短语做状语. 其中south前面省略to the .由于coast是地势较低处,所以用down to the coast.
⒊ There could be as many as six hundred thousand sheep fed within six miles of Salisbury, measuring every way round and the town in the centre.
⑴句中fed within six miles of Salisbury是一个过去分词短语修饰sheep,measuring…是一个V-ing短语,修饰six miles of Salisbury。
⒋ The cathedral is famous for the height of its tower, which is without doubt the highest and the most handsome in England, being from the ground 410 feet.
⑴without doubt=certainly无疑地;确定地
e.g. Without doubt, our team will win the game.
⑵ being from the ground 404 feet在此句中做状语,用语说明tower的高度。
⒌ Neither of them is very big, but they become a larger river when joined together, and yet larger when joined by a third river.
⑴ a third river又一条河流,不定冠词a 用在序数词之前,表示“再一次, 又一”。
E .g. You can have a second try if you fail the first time.
⑵Neither of the books is interesting.(这2本书都没意思。)表示“两者都”,用both of+复数名词,表复数概念。
E.g. Both of you have to go there.
⒍ …, which employ the poor of a great part of the country round-namely, making cloth and sheets,
namely 副词,即,就是,用以补充或具体说明前面已提到的事物
e.g. Two boys are late for school today-namely, Tom and Jim.
⒎ …with many small and clear rivers, and rich fields bearing fruit and grain.
⑴bearing fruit and grain做宾语补足语,bear“结果实”,产生,长出
e.g. The tree is bearing a lot of apples this year.
⑵ with +宾语+v-ing,在此做状语。
E.g. With you standing here, we can’t work.

教 师 活 动 内 容、方 式 学 生 活 动 内 容、方 式 旁 注
Step1: Greeting and Analysis
Analyze the whole paper and praise some Ss. At the same time, encourage some Ss who failed to pass the exam.
Step2: Single choice
Check the answers with the whole class, then choose some difficult ones to explain to the Ss.
1. In general, the northerners are keen on dumplings while the southerners are fond of rice.
此句中in common即共同的与句意不符合,in total为总共,总计,而in particular为特别的,也不对。只有表示大体上一般的in general 才正确。
2. The news has spread all the country that the spaceship succeeded in returning to the earth.
The news that为同位语从句,对news进一步说明解释。
3.Scoland lies to the north of England; it is part of Britain.
表示位置的词to可接壤可不接壤,不在一个范围内,on表示两地接壤或者在河岸上,off表示远离,in表示在范围内。England和Scotland不在一个范围内用to,而它是属于Britain的一部分,所以用part。而be part of表示前者是后者的一部分。
4.run over 表示从。。。上碾过或者水满溢出,the cup was full and the water in it was running over
5. ---What made her so sad?
. ---That she failed in the examination.

这里state 表示状况,它现在的情况,用in。e. g in a poor state of health。健康状况不好。同时state 有国家。州。政府的意思。
