初中七年级数学详细内容
七年级上册 第一章有理数 1.1 正数和负数 正数和负数的定义:大于零的数叫正数,正数前面加上负号叫负数. 正负数的实际应用背景:在同一个问题中,分别用正数和负数表示的量具有相反的意义. 阅读与思考用正负数表示加工允许误差 用正负数表示某个范围的实例 1.2 有理数 有理数的定义(两个整数的比值!!!),有理数的分类. 数轴和数轴的三要素:规定了原点、正方向和单位长度的直线叫数轴. 用数轴表示数的方法:一般地,设a是一个正数,则数轴上表示数a的点在原点的右边,与原点的距离是a个单位长度;表示数-a的点在原点的左边,与原点的距离是a个单位长度. 关于原点对称:一般地,设a是一个正数,数轴上与原点的距离是a的点有两个,它们分别在原点左右,表示-a和a,我们说这两点关于原点对称. 相反数:只有符号不同的两个数叫做互为相反数.一般地,a和-a互为相反数.特别地,0的相反数仍是0. 绝对值:一般地,数轴上表示数a的点与原点的距离叫做数a的绝对值. 求绝对值的方法:一个正数的绝对值是它本身,一个负数的绝对值是它的相反数,0的绝对值是0.这就说,当a是正数时,|a|=a;当a是负数时,|a|=-a;当a=0时,|a|=0. 比较有理数大小的方法:1)正数大于0,0大于负数,正数大于负数;2)两个负数,绝对值大的反而小.(总之,在数轴上右边的数大于左边的数!) 1.3 有理数的加减法 有理数加法法则:1)同号两数相加,取与加数相同的符号,并把绝对值相加.2)绝对值不相等的异号两数相对,取绝对值较大的加数的符号,并用较大的绝对值减去较小的绝对值,互为两反数的两个数相加得0.3)一个数同0相加,仍得这个数. 加法操作顺序:先定符号,再算绝对值. 加法的运算律:加法交换律,加法结合律. 有理数减法法则:减去一个数,等于加上这个数的相反数. 加减混合运算:引入相反数后,加减混全运算可以统一为加法运算:a+b-c=a+b+(-c). 实验与探究填幻方 阅读与思考中国人最先使用负数 1.4 有理数的乘除法 有理数乘法法则:1)两数相乘,同号得正,异号得负,并把绝对值相乘.2)任何数同0相乘得0. 倒数:乘积是1的两个数互为倒数.(小学学过) 连乘时的符号确定:几个不是0的数相乘,负因数的个数是偶数时,积是正数;负因数的个数是奇数时,积是负数.
一对一英语教学的心得
一对一英语教学的心得体会 一对一教学与一对多教学有很多的不同，很多来进行一对一辅导的学生基本都是在学校的大班课堂知识掌握得不扎实，没跟上老师的教学进度，或是面临毕业考试等，所以我认为一对一教学的重点是复习知识。 众所周知，复习是教学活动的重要环节,是教师带领学生将所学全部知识进行整理,查缺补漏,使学生对所学知识进一步巩固,掌握得更加扎实,所以组织复习是提高教学质量的关键。下面我将结合我的英语教学实践,谈谈合理有效组织复习的“五要”和“五忌”。 一、要目标明确,忌盲目施教 教师要充分认识复习的关键性作用,认真对待复习,纠正复习就是简单地领着学生读读写写背背考考的错误思想。教师要吃透教材,制定详细的复习计划，比如利用多长时间进行复习;复习内容有哪些;学生要掌握的重点、难点有哪些;采取什么措施有效地组织复习;学生对各部分内容的听说读写分别达到什么要求等等,从而做到心中有数、目标明确。 二、重扎实有效,忌走马观花 课堂教学是提高教学质量的主渠道,上好复习课是提高复习质量的关键所在。一般来说,复习时先是"通教材",逐课对单词、句子、语法、课文、对话进行强调巩固。在教学过程中教师要吃透教材,把握重难点,明确任务:单词--音、形、义;句子--听、说、读、写;对话--背诵、理解;语法--简单的概括总结、讲解。教师在复习每一课时,从单词、句子的听写,到对话的熟读、背诵,要求学生当堂掌握的一定不能拖到课后,今天需要解决的务必今天完成。 三、重自主学习,忌教师串讲 有的教师在复习过程中反复讲解重难点,事必亲恭,累得够呛,效果却并不理想。新课程理念倡导在教学中培养学生的自主学习能力,所以教师得开动脑筋,变换方式,调动学生的学习积极性,合理推行小组学习,让学生当学习的主人。老师可以通过要学生听写，翻译，背课文等方式测试学生学习效果，并针对成绩给予相应的奖励，合理有效的评价方式让学生始终保持高昂的学习积极性。 四、要灵活创新,忌呆板教条 教学中要遵循因材施教，灵活创新。比如在《小学英语教学基本要求》中规定小学阶段不讲解语法,但我是这样理解和实施教学的:虽然不要求讲解语法,但简单地向学生渗透一些语法知识能够帮助学生更好系统地把握所学知识。所以我对两种常用的时态(一般现在时、现在进行时),三种句式(特殊疑问句、一般疑问句、选择疑问句),be动词(am,is,are),名词单复数,动词的第三人称单数形式等都进行了简明扼要的讲解。特殊疑问句重点让学生掌握疑问词:where,when,what time,who,whose,what,how, how many,how much,how old, what color,what，why,明确问什么用哪个疑问词,能够进行区分。一般疑问句让学生明确开头的引导词是:be动词或do,does等,回答一般是Yes或No。选择疑问句要选择其中一个答案回答。语法讲解要注意把握度,不要给学生上成纯粹的系统的高深的语法课,学生往往很难理解,难以取得理想效果,最好是结合课本实际简单明了的举例讲解,既帮助理解课本,又明确一定的语法规则,让学生能够活学活用。 五、重兴趣习惯,忌短期效应 有的教师习惯把新授课上得生动有趣,而复习课除了读写背,就是练习、做题,学生兴趣索然。我们对待复习课应当像新授课一样,在教学中仍然采用说说、唱唱、玩玩、演演等方式,激发并持久保持学生的学习兴趣。而在复习过程中的学生习惯培养要突出以下几方面:标准的语音语调:教师要培养学生听录音的好习惯,在复习中反复听录音有助于学生模仿纯正地道的语音语调,久而久之,学生的发音就会胜过老师,听力也得到很好的锻炼和提高。良好的做

初中数学七年级上册知识点总结(最新最全)
提分数学七年级上知识清单 第一章 有理数 一．正数和负数 ⒈正数和负数的概念 负数：比0小的数 正数：比0大的数 0既不是正数，也不是负数 注意：①字母a 可以表示任意数，当a 表示正数时，-a 是负数；当a 表示负数时，-a 是正数；当a 表示0时，-a 仍是0。（如果出判断题为：带正号的数是正数，带负号的数是负数，这种说法是错误的，例如+a,-a 就不能做出简单判断） ②正数有时也可以在前面加“+”，有时“+”省略不写。所以省略“+”的正数的符号是正号。 2.具有相反意义的量 若正数表示某种意义的量，则负数可以表示具有与该正数相反意义的量，比如： 零上8℃表示为：+8℃；零下8℃表示为：-8℃ 支出与收入;增加与减少;盈利与亏损;北与南;东与西;涨与跌;增长与降低等等是相对相反量，它们计数： 比原先多了的数,增加增长了的数一般记为正数;相反，比原先少了的数，减少降低了的数一般记为负数。 3.0表示的意义 ⑴0表示“ 没有”，如教室里有0个人，就是说教室里没有人； ⑵0是正数和负数的分界线，0既不是正数，也不是负数。 二．有理数 1.有理数的概念 ⑴正整数、0、负整数统称为整数（0和正整数统称为自然数） ⑵正分数和负分数统称为分数 ⑶正整数，0，负整数，正分数，负分数都可以写成分数的形式，这样的数称为有理数。 理解：只有能化成分数的数才是有理数。①π是无限不循环小数，不能写成分数形式，不是有理数。②有限小数和无限循环小数都可化成分数，都是有理数。 2. (1)凡能写成 )0p q ,p (p q ≠为整数且形式的数，都是有理数.正整数、0、负整数统称整数；正分数、负分数统称分数；整数和分数统称有理数.注意：0即不是正数，也不是负数；-a 不一定是负数，+a 也不一定是正数；π不是有理数；
浅谈外教一对一学英语口语
浅谈外教一对一学英语口语 对于英语口语的学习，不同的人会选择不同的方法，有人选择英语角，有人找个老外当朋友，有人选择完全自学，确实有不少人通过这些方法提升了口语水平，但由于这些途径中的partner们鱼龙混杂、水平参差不齐，很难保证口语的标准程度和地道程度，所以多数人的进步并不大，或者没有专业程度上的长进。而与之相对的，有一种更专业、更系统的口语学习方法，那就是请个外教。前几年，更多的是英语培训机构推出的外教口语班，多为大班授课或小班授课，但近几年，有不少机构推出了外教一对一的口语学习形式，因为尝试过的人还是少数，所以网上有很多人在问：外教一对一学英语口语的效果好吗？这篇文章中，abc360专家就将为你解读一下外教一对一效果到底效果好不好。 一外教一对一可以提供母语交流环境，是口语学习的最佳环境。 英语和汉语在思维方式上存在巨大差别，而且语言本身就是对一种文化的承载，在这一方面，即使再资深的中国英语教师都是无法逾越的，所以只有来自英语国家的外教才能真正教会你地道的语言表达方式和纯正的英语式思维。尤其是外教一对一，这个环境中只有你和外教两个人，外教以自己的母语和你交流，等于完全还原了一个英语国家的语言环境，就像把你的置身于国外，让你直接和外国人交流，口语的进步当然会很快。不过，如果你的英语基础非常薄弱，在最开始的时候和外教交流会很吃力，但只有突破了这个难关，你的英语口语之路才会更加顺利，今后的进步才会更大。 二外教一对一更有针对性，外教一对一开口练习的机会也更多。 无论是大班授课、小班授课还是英语角，最大的问题就是成员水平参差不齐，老师和话题主导者只能顾及大多数，那些基础薄弱或者不敢开口的成员只能越来越被边缘化，时间久了也许口语不但没有长进反而对话。而外教一对一的课堂上只有两个人，只要有一个人不说话，课程就无法进行下去，这就使你不得不开口，不得不尽可能地与外教聊天，而且，伯瑞英语的老师会非常了解你的现有水平、优势、劣势、性格、喜好等，并根据你自己的特点为你量身定制最适合你的课程，而且还能根据你的学习进度随时调整你的课程内容。另外，伯瑞英语的口语课程还有一个其他形式无法替代的优势，就是上课的时间、地点可以根据学员的要求灵活安排，也就是可以上门授课，这样就基本避免了缺课情况的发生，口语的练习更加持之以恒。 三外教的品质如何，直接决定了口语学习效果的好坏。 外教一对一口语学习的效果还取决于一个非常重要的因素，那就是外教的水平。如果随便在网上或者咖啡厅之类的场所找个老外学口语，很可能得不偿失。因为英语也是有方言之分的，不同的老外口语发音也不尽相同，只有经过专业资质认证的外教才能教会你最标准的英语发音和专业的表达方式。伯瑞英语的老师都是经过专业严格的认证的。假如在请外教的时候没有考核好资质，很可能在练了很久之后，感觉自己的口语表达比较顺利之时，却发现学了一
