《故都的秋》《荷塘月色》《我与地坛》群文阅读说课稿 2022-2023学年统编版高中语文必修上册
(2) 中国文人的悲秋情结。3.《荷塘月色》中，作者为什么要离开家来到荷塘散步？4. 思考：作者的心里为何“颇不宁静？”（教师补充：写作背景）5. 出门散步后，作者的心情发生变化了吗？ 有怎样的变化？6.思考讨论：为什么作者说“我”与“地坛”间有着宿命般的缘分，二者有何相似之处？（阅读1-5段）7.思考：作者从他同病相怜的“朋友“身上理解了怎样的”意图“？三、课堂总结李白说：“天地者，万物之逆旅也。”人生，如同一场旅行，在人生的旅途中，时而高山，时而峡谷，时而坦途，时而歧路。我们或放歌，或悲哭，然而，大自然始终以其不变的姿势深情地看着我们，而我们，也应该学会在与自然的深情对望中，找到生命的契合。正如敬亭山之于李白，故都的秋之于郁达夫，荷塘月色之于朱自清，地坛之于史铁生，他们从中或得到心灵的慰藉、精神的寄托，或得到生存的智慧与勇气，最终完成精神的超脱。
《一个消逝了的山村》说课稿 2021—2022学年统编版高中语文选择性必修下册
这几段内容传达出的是“要敬畏生命，尊重生命；更要敬畏大自然，尊重大自然，爱护大自然”的主旨内涵，因此让学生通过自由朗读的方式，再次体会冯至对这个消逝了的山村的细致的美好的描绘，感悟冯至传达出的对生命，对自然的理解和思考。5.最后一个自然段的解读依然是交给学生，先齐读课文，再让学生自主分享自己的体会或疑惑。但在这一环节我也设计了两个我认为必须解答的两个问题，一是怎么理解“在风雨如晦的时刻”；二是“意味不尽的关联”是指什么。我认为这两个问题一个涉及到写作背景，一个涉及到对全文主旨的一个整体把握，能够进一步帮助学生理解散文的深刻内涵和主旨，让学生有意识的在阅读散文过程中通过背景知识进行理解。既尊重学生的个性化解读，又能够让学生有意义学习，完成预设的教学目标。如果学生没有提到这两处，那我就需要做出补充。

本节课是新版教材人教A版普通高中课程标准实验教科书数学必修1第四章第4.5.1节《函数零点与方程的解》，由于学生已经学过一元二次方程与二次函数的关系，本节课的内容就是在此基础上的推广。从而建立一般的函数的零点概念，进一步理解零点判定定理及其应用。培养和发展学生数学直观、数学抽象、逻辑推理和数学建模的核心素养。1、了解函数（结合二次函数）零点的概念；2、理 解函数零点与方程的根以及函数图象与x轴交点的关系,掌握零点存在性定理的运用；3、在认识函数零点的过程中，使学生学会认识事物的特殊性与一般性之间的关系，培养数学数形结合及函数思想； a.数学抽象：函数零点的概念；b.逻辑推理：零点判定定理；c.数学运算：运用零点判定定理确定零点范围；d.直观想象：运用图形判定零点；e.数学建模：运用函数的观点方程的根；
抛物线及其标准方程教学设计人教A版高中数学选择性必修第一册
本节课选自《2019人教A版高中数学选择性必修第一册》第二章《直线和圆的方程》，本节课主要学习抛物线及其标准方程在经历了椭圆和双曲线的学习后再学习抛物线，是在学生原有认知的基础上从几何与代数两 个角度去认识抛物线.教材在抛物线的定义这个内容的安排上是：先从直观上认识抛物线，再从画法中提炼出抛物线的几何特征，由此抽象概括出抛物线的定义，最后是抛物线定义的简单应用.这样的安排不仅体现出《课程标准》中要求通过丰富的实例展开教学的理念，而且符合学生从具体到抽象的认知规律，有利于学生对概念的学习和理解.坐标法的教学贯穿了整个“圆锥曲线方程”一章，是学生应重点掌握的基本数学方法 运动变化和对立统一的思想观点在这节知识中得到了突出体现，我们必须充分利用好这部分教材进行教学
双曲线及其标准方程教学设计人教A版高中数学选择性必修第一册
∵在△EFP中,|EF|=2c,EF上的高为点P的纵坐标,∴S△EFP=4/3c2=12,∴c=3,即P点坐标为(5,4).由两点间的距离公式|PE|=√("(" 5+3")" ^2+4^2 )=4√5,|PF|=√("(" 5"-" 3")" ^2+4^2 )=2√5,∴a=√5.又b2=c2-a2=4,故所求双曲线的方程为x^2/5-y^2/4=1.5.求适合下列条件的双曲线的标准方程.(1)两个焦点的坐标分别是(-5,0),(5,0),双曲线上的点与两焦点的距离之差的绝对值等于8;(2)以椭圆x^2/8+y^2/5=1长轴的端点为焦点,且经过点(3,√10);(3)a=b,经过点(3,-1).解:(1)由双曲线的定义知,2a=8,所以a=4,又知焦点在x轴上,且c=5,所以b2=c2-a2=25-16=9,所以双曲线的标准方程为x^2/16-y^2/9=1.(2)由题意得,双曲线的焦点在x轴上,且c=2√2.设双曲线的标准方程为x^2/a^2 -y^2/b^2 =1(a>0,b>0),则有a2+b2=c2=8,9/a^2 -10/b^2 =1,解得a2=3,b2=5.故所求双曲线的标准方程为x^2/3-y^2/5=1.(3)当焦点在x轴上时,可设双曲线方程为x2-y2=a2,将点(3,-1)代入,得32-(-1)2=a2,所以a2=b2=8.因此,所求的双曲线的标准方程为x^2/8-y^2/8=1.当焦点在y轴上时,可设双曲线方程为y2-x2=a2,将点(3,-1)代入,得(-1)2-32=a2,a2=-8,不可能,所以焦点不可能在y轴上.综上,所求双曲线的标准方程为x^2/8-y^2/8=1.

人教A版高中数学必修二简单随机抽样教学设计
知识探究（一）：普查与抽查像人口普查这样，对每一个调查调查对象都进行调查的方法，称为全面调查（又称普查）。 在一个调查中，我们把调查对象的全体称为总体，组成总体的每一个调查对象称为个体。为了强调调查目的，也可以把调查对象的某些指标的全体作为总体，每一个调查对象的相应指标作为个体。问题二：除了普查，还有其他的调查方法吗？由于人口普查需要花费巨大的财力、物力，因而不宜经常进行。为了及时掌握全国人口变动状况，我国每年还会进行一次人口变动情况的调查，根据抽取的居民情况来推断总体的人口变动情况。像这样，根据一定目的，从总体中抽取一部分个体进行调查，并以此为依据对总体的情况作出估计和判断的方法，称为抽样调查（或称抽查）。我们把从总体中抽取的那部分个体称为样本，样本中包含的个体数称为样本量。
