北师大版小学数学六年级上册《统计图的选择》说课稿
一、教材分析1.教材的地位和作用本节教材是北师大版六年级数学上册第5章《数据的收集与整理》第3节的内容，这一章是《全日制义务教育数学课程标准（实验稿）》第三学段“统计与概率”部分的第一章，也是基础章节。它让学生经历数据的收集、整理、描述的过程，体会适当选择统计图表对描述实际问题的作用，为以后进一步学习统计的有关知识打下基础2.学情分析学生在此之前已经在小学阶段学习过有关统计图表的知识，对三种统计图也有了一定的认识和感知，会画三种统计图，但是对于究竟如何选取适当的统计图去说明一些具体实际问题还存在一定困难，所以本节内容主要是让学生对三种统计图各自的特点和优势有一定的认识。3.教材重难点根据对教材的研读和学生学情的分析，结合新课标对本节的要求，特将本节的重难点确定如下：
北师大初中数学七年级上册统计图的选择说课稿
四、教学过程分析为有序、有效地进行教学，本节课我主要安排了以下教学环节：（一）复习导入主要复习一下三种统计图，为接下来介绍三种统计图的特点及根据实际问题选取适当的统计图做好知识准备。（二）问题探究选取课本上“小华对1992～2002年同学家中有无电视机及近一年来同学在家看电视的情况”的3个调查项目，进而设计3个探究问题从而加深学生对每一种统计图的进一步认识，至此用自己的语言总结出每一种统计图的特点。（三）实践练兵这一环节通过2个实际问题的设计，通过学生对问题的分析、讨论，使学生认识到适当选取统计图有助于帮助人们去更快速、更准确地获取信息。（四）课堂小结总结这一节课所学的重点知识，这部分主要是让学生自己去总结，看看这节课自己有哪些收获。（五）作业布置进一步巩固本节课所学的知识，达到教学效果。以上就是我对这节课的见解，不足之处还望批评和指正。

天上有明月，年年照相思。她夜夜沉醉在梦中。梦把空间缩短了，梦把时间凝固了，梦把世界净化了。梦中没有污秽，没有嘈杂，没有邪恶；梦中没有分离，没有创伤，没有痛苦；梦中只有柔和的月色，只有温馨的爱；梦使她永远年轻，使她不原醒来。…………啊，那个世界，是为天下最真最善最美的心灵准备的，艺术家怀着虔诚的情感，用充满魔力的琴弦，在人们的心中筑起了一座不朽的天堂，它像天地一样长久，日月一样永恒！新月微微地闭着眼睛，她清清楚楚地看到了那座天堂，真真切切地触到了那座天堂，冰凌砌成墙壁，白云铺成房顶，雾霭织成纱幔，星星串成明灯；在那里，她的头发像沐浴之后那样清爽柔软，随风飘拂，她的肌肤像披着月光那样清凉润滑，她的那颗心啊，像浸润着蒙蒙细雨的花蕾，挂着晶莹的露珠，自由地呼吸……她沉醉在那个一尘不染的美好的境界，如歌如诗，如梦如幻，如云如月，如水如烟……

1、变换角度，多向思维（多向思维要求思维能针对问题，从不同角度，用多种方法去思考问题。对于作文而言，就是要使学生学会对同一问题，同一素材，同一题目，同一体裁的不同进行区分。）请学生从这则材料中分析出几个角度，准备课堂交流：19世纪法国著名科幻小说家儒勒?凡尔纳，一生写了104部科幻小说。当初他的第一部科幻小说《气球上的星期五》接连被15家出版社退回。他当时既痛苦又气愤，打算将稿子付之一炬。他妻子夺过书稿，给他以鼓励。于是他尝试着走进第16家出版社。经理赫哲尔阅读后，当即表示同意出版，还与儒勒?凡尔纳签订了为期20年的写作出版合同。这则材料叙述时没有一定的中心，属于开发性材料，分析材料中人物、人物关系、故事的不同侧面，可以从不同角度得出结论：
人教版高中语文必修3《学会宽容 学习选择和使用论据》教案2篇
评价分析法，就是引述事例后，对所引述的事例作适当的评价，从而使自己的观点得到印证。例如，在论“节俭”时，引用了“曾国藩以俭戒子，其子曾纪泽终成出色的外交家；方志敏居官不贪，一生清贫，千古留名”的事实后，接着进行分析：是的，“俭者心常富”，节俭能培养人同困难作斗争的勇气和意志，而这正是一个人立业最重要的素质。从这个意义上说，有人说饥饿是人生的佐料，吃苦是一种资本也不无道理，而自觉和戒奢尚俭则更是促人修身养性，磨炼意志的有效途径。这里，作者紧扣论点，对论据进行了评价性分析，这种评价分析使作者的观点得到强化。（四）因果分析法因果分析法，就是抓住论据所述的事实，并据此推求形成原因的一种分析方法。事出必有其因。我们可以依据事物发展变化的因果关系，由事物发展变化的结果，推导出产生这种结果的原因，从而揭示出一定的生活规律，使事例有力地证明观点。

I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.
