    人教版新课标小学数学三年级下册商中间或末尾有0的除法说课稿2篇

    教法、学法分析我通过阅读教材、教参和新课标,分析学生学习状况,认为对这一教学内容理解起来比较容易。所以,在教学时我准备采取以下策略:1、放手让学生自主解决问题,尝试计算例7的1、2题。再通过学生口述计算过程,教师设问、强调重点使学生掌握本节课知识。2、通过学生反复叙述算理,培养学生口头表达能力,并使他们自主探索“被除数中间或末尾没有0,商中间或末尾有0”这一知识形成的过程。教学目标1、在熟练掌握一位数笔算除法法则的基础上,会正确计算商中间或末尾有0的除法的另一种情况。2、能熟练地进行商中间有零和末尾有零的除法,形成一定的笔算技能。3、能结合具体情境估算三位数除以一位数的商,增强估算的意识和能力。

    北师大初中数学七年级上册科学记数法说课稿

    [设计说明]:只给出情景故事,感知了一个大数,这样还不能引起学生对大数的深刻认识,所以再给出宇宙星空中的这些大数,让学生读读、看看这些数,引起学生强烈的认知上的冲突,形成一种心理上的想读、想写的求知欲望。(二)、引出问题、探索新知在上面的例子中,我们遇到了几个很大的数,看起来、读起来、写起来都不方便,有没有简单的表示法呢?分以下步骤完成。1、回忆100 ,1000,10000,能写成10( )2、300=3×100=3×10( )3000=3×1000=3×10()30000=3×10000=3×10()3、再由学生完成上面4个例子中的数的表示。(学生对160 000 000 000这个数可能表示为、16×1010,教师要利用学生这种错误,强调a的范围)4、教师给出科学记数法表示:a×10( )(1≤a<10)。[设计说明]:通过层层递进的探究设计,启发学生成功地发现“科学记数法”的表示方法,同时又通过学生示错,让学生记住a的范围,体现了以学生为主的探究式教学。

    接下来学生类比有理数中相关概念,体会到了实数范围内的相反数、倒数、绝对值的意义,并进一步掌握了实数的相反数、倒数、绝对值等知识。学生类比有理数中相关运算,体会到了实数范围内的运算及运算律。并探讨用数轴上的点来表示实数,将数和图形联系在一起,让学生进一步领会数形结合的思想,利用数轴也可以直观地比较两个实数的大小。然后通过相关练习,检测学生对实数相关知识的掌握情况。最后学生交流,互相补充,完成本节知识的梳理。布置作业:所布置作业都是紧紧围绕着“实数”的概念及运用。设计选作题是为了给学有余力的学生留出自由发展的空间。五、关于板书设计我将板书设计为“提纲式”。这样设计主要是力求重点突出,能加深学生对重点知识的理解和掌握,便于记忆。

    然后能通过图象找出变量的对应关系在图象上的体现。3、做一做:课本P154第1小题,学生在课本上填表,让学生通过填表,体会变量之间的相依关系。4、师生小结:和学生一起对刚才的三个例子进行总结,启发学生思考三个例子的相同点和不同点,如表现形式不同,有图象、表格、代数表达式。相同的有它们都是两个变量,确定其中一个变量后就能相应确定另一个变量的值。从而使学生的认识上升一个高度,并掌握函数的概念5、课堂练习:完成课本P155随堂练习。通过本练习的完成巩固概念并会用概念去判断两个变量间的关系是否可看做函数。6、新课巩固:以填空形式对本堂课进行小结,使学生对函数的概念及应用有一定记忆。并通过对最后问题的思考使学生意识到数学来自生活,并能应用于生活。

    人教部编版七年级下册回忆鲁迅先生(节选)教案

    《回忆鲁迅先生》(节选)是一篇典型的有较长篇幅的散文。本教学设计以点带面,长文短教,设计了这样一个问题:“作者在文中为鲁迅先生塑造了多个身份,具体有哪些?”如此化繁为简,使课堂教学脉络清晰。学生在阅读长篇幅文章时有了抓手,就可以有条理地去思考,形成系统性思维,直达教学目标。本教学设计还要求学生进行批注式阅读,直入文本。学生围绕“说说鲁迅先生身上有哪些优秀的品质让学生萧红印象深刻?”做赏析式或者评价式批注,让学生在自读这篇文章时,将无目的阅读变为有效阅读,既提高了课堂效率,也让学生真正做到潜入文字之中,通过关注文章细节来深入把握文本。本教学设计整体上以学生自主学习为主,教师适当引导。遵从“整体感知内容—局部探究—体会情感”的一般阅读规律,以读为指引,让学生在读中感知内容,在读中把握人物形象,在读中体悟情感。各环节之间环环相扣,由浅入深,层层推进。

    1.了解演讲者的观点,领悟格物致知精神的内涵。2.梳理演讲者的思路,把握演讲词层层推进的结构。 一、导入新课 1974年,美籍华裔物理学家丁肇中向全世界宣布发现J粒子,开辟了人们认识微观世界的新境界,并因此于1976年获得了诺贝尔物理学奖,成为首位用中文在诺奖颁奖典礼上发表演讲的科学家,引起了世界的轰动。请同学们阅读下面这则材料,了解他取得这项伟大成就的经历。1974年以前,人们认为基本粒子都可以归纳为三种夸克。丁肇中对此持怀疑态度,但他想进行实验的想法却遭到了几乎所有国家大型实验室的反对。最终,他在美国布鲁克海文国家实验室开展了实验,经过两年多夜以继日地实验,终于发现了一种未曾预料过的新的基本粒子——J粒子,而它来自第四夸克。他的发现推翻了过去认为世界只由三种夸克组成的理论,为人类认识微观世界开辟了一个新的境界,被称为“物理学的十一月革命”。丁肇中也因此项发现在1976年获得了诺贝尔物理学奖。
