The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical.

导语在必修第一册中,我们研究了函数的单调性,并利用函数单调性等知识,定性的研究了一次函数、指数函数、对数函数增长速度的差异,知道“对数增长” 是越来越慢的,“指数爆炸” 比“直线上升” 快得多,进一步的能否精确定量的刻画变化速度的快慢呢,下面我们就来研究这个问题。新知探究问题1 高台跳水运动员的速度高台跳水运动中,运动员在运动过程中的重心相对于水面的高度h(单位:m)与起跳后的时间t(单位:s)存在函数关系h(t)=-4.9t2+4.8t+11.如何描述用运动员从起跳到入水的过程中运动的快慢程度呢?直觉告诉我们,运动员从起跳到入水的过程中,在上升阶段运动的越来越慢,在下降阶段运动的越来越快,我们可以把整个运动时间段分成许多小段,用运动员在每段时间内的平均速度v ?近似的描述它的运动状态。
4.写出下列随机变量可能取的值,并说明随机变量所取的值表示的随机试验的结果.(1)一个袋中装有8个红球,3个白球,从中任取5个球,其中所含白球的个数为X.(2)一个袋中有5个同样大小的黑球,编号为1,2,3,4,5,从中任取3个球,取出的球的最大号码记为X.(3). 在本例(1)条件下,规定取出一个红球赢2元,而每取出一个白球输1元,以ξ表示赢得的钱数,结果如何?[解] (1)X可取0,1,2,3.X=0表示取5个球全是红球;X=1表示取1个白球,4个红球;X=2表示取2个白球,3个红球;X=3表示取3个白球,2个红球.(2)X可取3,4,5.X=3表示取出的球编号为1,2,3;X=4表示取出的球编号为1,2,4;1,3,4或2,3,4.X=5表示取出的球编号为1,2,5;1,3,5;1,4,5;2,3,5;2,4,5或3,4,5.(3) ξ=10表示取5个球全是红球;ξ=7表示取1个白球,4个红球;ξ=4表示取2个白球,3个红球;ξ=1表示取3个白球,2个红球.
一、 问题导学前面两节所讨论的变量,如人的身高、树的胸径、树的高度、短跑100m世界纪录和创纪录的时间等,都是数值变量,数值变量的取值为实数.其大小和运算都有实际含义.在现实生活中,人们经常需要回答一定范围内的两种现象或性质之间是否存在关联性或相互影响的问题.例如,就读不同学校是否对学生的成绩有影响,不同班级学生用于体育锻炼的时间是否有差别,吸烟是否会增加患肺癌的风险,等等,本节将要学习的独立性检验方法为我们提供了解决这类问题的方案。在讨论上述问题时,为了表述方便,我们经常会使用一种特殊的随机变量,以区别不同的现象或性质,这类随机变量称为分类变量.分类变量的取值可以用实数表示,例如,学生所在的班级可以用1,2,3等表示,男性、女性可以用1,0表示,等等.在很多时候,这些数值只作为编号使用,并没有通常的大小和运算意义,本节我们主要讨论取值于{0,1}的分类变量的关联性问题.
一、谈话导入:师:咱们班今天是谁的值日生啊?学生反馈(教师请值日的学生回答并根据班级卫生情况做出简单评价或表扬。)师:今天的值日生表现非常棒,值日工作做的很好,希望其他同学向他(她)学习。那你们想不想把我们值日时的场面画在纸上呢?今天就让我们来学习第七课《今天我值日》。(打开课件)生:学生打开课本第七课《今天我值日》。
2学情分析中国传统绘画,源远流长,扎根于中华民族深厚的文化土壤之中。学习中国画,对继承和发扬我国民族绘画,有着非常重要的意义和作用。本课是在学生以前学习中国画基础上的进一步学习。中国画的门类很多,形式风格多样,彩墨画就是在水墨画的基础上发展而来的。而彩墨画特殊的风格和表现方法,是儿童艺术活动充满趣味的重要部分,用惯了彩笔、蜡笔的学生们对中国画有着强烈的兴趣。教材中选取了黄永玉先生的《红荷图》,画面中一朵朵荷花色彩奔放,线条朴拙生动,墨色在画面中自然融合,层次分明。作品中的荷花一改往日中国画清新淡雅的风格,娇艳欲滴的色彩让人为之倾倒。此外,教材中精选的朱德群的《无题》、何韵兰的《绿殇》,也较好地展现了中国画的笔墨及用色特点。墨的浓淡干湿、墨色的融合交错、运笔的轻重缓急,会产生丰富的画面效果。另外,教师也可让学生通过教科书中的技法图来进一步了解认识彩墨画。
2学情分析四年级学生处于儿童期的后期阶段,生理和心里变化很大,是培养学习能力、情绪能力、意志能力和学习习惯的最佳时期。学生已经从被动学习向主动学习转变,有了自己的想法。在绘画表达方面,已初步掌握了中国画工具和材料的使用方法,初步学会用写生的方式表现风景。在此基础上让学生依据写生的鸭子形象,尝试用水墨技法来表现,回顾已学知识,为新知学习做好铺垫。

一、说教材《开辟新航路》是高中《历史·必修二》第5课的内容。从三个方面向学生介绍了欧洲人开辟新航路的历史:即新航路开辟的原因和条件、新航路开辟经过以及影响。前4课内容介绍了古代中国经济的基本结构与特点,从第5课开始学习资本主义世界市场的形成和发展。本课内容相当重要,上承古代中国,下启近代世界。新航路的开辟,打破了世界相对隔绝的状态,世界真正开始融合为一个整体。从此,以西欧为中心的世界市场的雏形开始出现。随后的殖民扩张,世界市场拓展;第一次工业革命,世界市场基本形成;第二次工业革命,世界市场发展。二、说目标1、课程标准概述迪亚士、哥伦布开辟新航路的史实,认识地理大发现对世界市场形成的意义。2、三维目标①知识与能力:掌握新航路开辟的原因、经过、影响。②过程与方法:引导学生分析原因及影响,培养学生分析和归纳问题的能力。③情感态度与价值观:A、通过对新航路开辟过程的学习,使学生感受和学习探险家们勇于进取的开拓精神。B、通过学习新航路开辟的影响,使学生认识新航路开辟促进了人类社会的整体发展。

四、说教学程序(一).温故知新、导入新课复习提问:基因突变导致生物变异的原因是什么?回答:基因突变是基因结构发生改变,从而使遗传信息改变,使蛋白质结构改变、生物性状改变,即生物发生了变异。那么,基因是什么?它和染色体又有何关系?回答:基因是有遗传效应的DNA片断,染色体是DNA的载体,基因在染色体上呈线形排列。引出新知:对于一个生物体来说,正常情况下,其染色体的结构和数量都是稳定的。但在自然条件或人为因素的影响下,染色体的结构和数量均会发生改变,从而导致生物性状的改变,这就属于染色体变异。(二).把握重点、突破难点重点的把握:1、染色体结构的变异播放影片:猫叫综合征幼儿。让学生观察: 患儿哭声轻、音调高,很像猫叫。教师补充: 患儿的征状---两眼较低、耳位低下,存在着严重的智力障碍。阐述病因---染色体片段缺失
