篇2：新课标高一作文

新课标高一作文

“你今年幸福！新课标改革，我们连复读的机会都没有。最后一届又来挤我们了，我们高考可烦了！”姐姐投诉，送我上学。其实心里挺开心的。我比我姐还省，哈哈。开学第一天，我就慌了。书堆在我面前。哦，我的上帝！

原来有些科目一学期要学两本书，语文，数学，英语，物理等等。这怎么可能。一个学期要上两个学期的课。那不是多了一年半吗？应该用来复习吗？可怕，好像比上一个好不了多少。整整一年半的时间用来复习，会无聊死的。

一个学期过去了，除了整日整夜的.学习，没有什么额外的乐趣。最重要的是，我心里总有一块沉重的石头——高考。到现在高考的模式还没有出来，谣言很多，小综合，大综合，全日制考试.所以，在不确定的情况下，我们只能全方位的学习，而不能专注于此。努力当然是。如果以前是，很多学校估计从高一开始就开始学不同的科目了。虽然这种学习有利于个人的全面发展，但是我们的负荷能力是有限的，过度疲劳甚至可能得到相反的效果。4天的考试让我们身心俱疲，总分1350分，堪比我们的共同愤慨。

其实我觉得新课标没有太大的改革。我改了文，堵了最后一届，把培养能力放在第一位，改了高考。能力固然重要，但是高考决定输赢的模式还没有改革，怎么学已经死了。学分不能当饭吃。拿全学分的人的任务是冲刺高考，这似乎比以前多了一个环节。

还有好几天，还要考试，一学期要考四次。其实我个人觉得这些考试改革的时候为什么不一起改呢？你算算，月考一周，一学期四次一个月，三年考六个月！也就是半年！时间似乎不是没有，但我们没有遵循鲁迅的“压榨时间”的原则。如果课程改革改变了学习和教育的模式，那就根本改变了。如果能省下那六个月，可以在每学期期末一次性查漏补缺，也可以多留些时间复习备考。一年的学习足够了，半年可以把三年的书彻底巩固几遍。高中再多的班也不会是初中的四倍，学生都在成长。以前初中一个月可以复习完，现在多了一年半。所以，改革要更大胆更勇敢，变不可能为可能。我们各行各业的学生和老师一起努力改变真正的中国人自己的教育方式。

也希望我们的子孙能站在更高的地方感谢我们的“前辈”，呵呵。

篇6：新课标人教版初中化学教案

重点：水对人类的影响及水的组成

教学设计过程

本节课按一课时安排。但应在上课前一周给学生布置任务，由学生通过查阅文献，浏览相关网站，在充分准备的基础上进行展示活动，可以由学生采用自由组合的形式分成若干小组，展示自己的学习成果。

1.课前任务布置：

(1)阅读课文，思考下列问题，提出自己的见解：

①从外层空间看地球，看到地球表面大部分地区被水覆盖着，是一个名符其实的水球，水资源如此丰富，为什么还要加以规划和保护?

②在日常生活中，我们身边有浪费水的现象吗?结合自己的实际，我们生活中克服哪些不良行为，可以达到节约用水的目的?

③在我们周围，水资源保护的状况好吗?你认为哪些行为会使水质受到不良影响?

④从目前来看，淡水缺乏是一个全球性的问题，特别是有些地区，干旱严重威胁着人类的生存，而地球上海水是丰富的，你有什么好设想，使海水得以充分利用?(必须是自己的设想，不一定正确，不必追求科学性，但需从可行性和经济角度出发)。

⑤你认为日常生活中改变人的哪些生活习惯可以做到节省淡水?举具体措施或归纳一些节水的小窍门。

(2)查阅相关网站，从网上获取相关信息，结合自己的观点，对这些信息进行加工，证明自己的观点是正确的或措施是可实施的。

(3)2-3人一组(自由组合)，将自己的学习成果制作成Powerpoint演示文稿或制作成小展板，供课堂交流用。

2.课前准备工作：

教师课前可以将学生收集到的各种素材浏览，对观点(或措施)相近的小组的方案加以整理，有助于讨论进行得全面。对有创意、有价值的的设想，不考虑其可行性或严谨性，充分发挥学生的想象力，使教学过程变得活泼。

3.课堂教学：

分为两个阶段。

(1)教师将课题引入后，由学生将学习成果进行展示，师生之间相互质疑、相互释疑，此过程大约用时25分钟。教师可将已收集的资料片当堂播放，加深学生对水资源保护、水资源合理开发利用的认识。

(2)由教师以实验为突破口，演示电解水的实验，根据电解过程中两极产生气体的性质检验，得出水的元素组成，再根据气体的体积、，两种气体的密度，推导水的组成。

(完成电解水的实验使用霍夫曼水电解器，若没有，可根据教学参考书P89的装置自行制作，所用试管选用带刻度的，以便于寻找电解产物量的关系。为增强水的导电能力，实验前应在水中加少量稀硫酸，但这一点一定事先向学生做交待。避免与初中物理可的有关知识矛盾。)

4.课后小结：

对本节知识内容进行小结，简要介绍建国以来兴建的水利工程，将搜集到的图片、视频资料做展示，加强对学生进行节约用水的教育。最后将制作精美的展板放于墙报展览。

篇7：人教版新课标同步作文

中考过后的暑期漫长而乏味，按捺不住的我产生了打工的念头。首先觉得新鲜，其次觉得好玩，再加上又有的赚，何乐而不为呢?经在西安上学的哥哥介绍，我当上一家泡馍馆的服务生。一个月的服务生生活让我觉觉得有苦有甜。

作为中学生，假期本应在家学习或有机会外出旅游，看看祖国的大好河山。而有人却因为种种原因选择不同的方式，外出打工。我是很赞同这一点的，现在的孩子都是独生子女，因此，所有的父母对其都宠爱有加，致使其娇生惯养。而外出打工则是最好的锻炼机会。体验大人的生活，懂得大人在外的不易，并且自己赚得零用钱，而养成节省的好习惯。如果做的工作与家庭接近，说不定会由小公主变成爸妈的好帮手。对于自理能力比较弱的人，这也是一个锻炼的好机会。当然，所有事物都有利有弊，有的利大弊，而有的弊大于利。打工也一样。

外出打工，对于中学生而言，我想最大的弊端就是结识到一些对自己无益的朋友，中学生的身心尚未成熟对于社会上的人与事识别能力较弱，以致于分辨不清好与坏。严重的便会走上不归路，或者是因为小而受到欺负，这些都有可能。但毕竟可以学会最起码的为人处事。

打工对于中学生而言，肯定是件很辛苦的事情，如果你能从中找到乐趣，那么它会是一件很有趣的事情。我以为如果你可以辨别好与坏，那么，打工将是一个具有特殊意义的事情，我想它一定会为人生增加色彩。

篇8：新课标人教版高一化学复习提纲

从实验学化学

第一节化学实验基本方法

一、熟悉化学实验基本操作

危险化学品标志，如酒精、汽油——易然液体;浓H2SO4、NaOH(酸碱)——腐蚀品

⑤萃取：利用混合物中一种溶质在互不相溶的溶剂里溶解性的不同，用一种溶剂把溶质从它与另一种溶剂所组成的溶液中提取出来。

2、粗盐的提纯

(1)粗盐的成分：主要是NaCl还含有MgCl2、CaCl2、Na2SO4、泥沙等杂质

(2)步骤

①将粗盐溶解后过滤;

2-2+2+2+②在过滤后得到粗盐溶液中加过量试剂BaCl2(除SO4)、Na2CO3(除Ca、过量的Ba)、NaOH(除Mg)

溶液后过滤;

2--③得到滤液加盐酸(除过量的CO3、OH)调PH=7得到NaCl溶液;

④蒸发、结晶得到精盐。加试剂顺序关键：(a)Na2CO3在BaCl2之后;(b)盐酸放最后。

3、蒸馏装置注意事项

①加热烧瓶要垫上石棉网;

②温度计的水银球应位于烧瓶的支管口处;

③加碎瓷片的目的是防止暴沸;

④冷凝水由下口进，上口出。

4、从碘水中提取碘的实验时，选用萃取剂应符合原则

①萃取剂不能与被萃取的物质反应

②萃取剂与原溶液溶剂互不相溶。(密度：苯<水

用CCl4萃取碘水中的碘时，溶液分为两层，上层液体显黄色，下层液体显紫红色。用苯萃取碘水中的碘时，溶液分为两层，上层液体为紫红色;下层液体显黄色。

三、离子的检验

2-①SO4：[ 用BaCl2溶液(或Ba(NO3)2溶液)、稀硝酸检验 ]先加稀硝酸酸化，再加BaCl2溶液有白色沉

2-2+2-淀，原溶液中一定含有SO4。 Ba+SO4=BaSO4↓

-②Cl：(用AgNO3溶液、稀硝酸检验)加AgNO3溶液有白色沉淀生成，再加稀硝酸沉淀不溶解，原溶液中

--一定含有Cl;或先加稀硝酸酸化，再加AgNO3溶液，如有白色沉淀生成，则溶液中一定含有Cl。 +-Ag+Cl=AgCl↓。

2-③CO3：(用BaCl2溶液、稀盐酸检验)先加BaCl2溶液生成白色沉淀，再加稀盐酸，沉淀溶解，并生成

2-无色无味、能使澄清石灰水变浑浊的气体，则原溶液中一定含有CO3。

④NH4：(用NaOH溶液检验)加入NaOH溶液，加热，放出使湿润的红色石蕊试纸变蓝的气体(NH3)，则

+原溶液中有NH4。

+-NH4+OH==NH3↑+H2O

第二节化学计量在实验中的应用

1、物质的量(n)是国际单位制中7个基本物理量之一。

3、各个量之间的关系

4、溶液稀释公式：(根据溶液稀释前后，溶液中溶质的物质的量不变)

C浓溶液V浓溶液=C稀溶液V稀溶液 (注意单位统一性，一定要将mL化为L来计算)

5、溶液中溶质浓度可以用两种方法表示：①质量分数W，②物质的量浓度C。质量分数W与物质的量浓度C

3的关系：C=1000ρW/M(其中ρ单位为g/cm)

3已知某溶液溶质质量分数为W，溶液密度为ρ(g/cm)，溶液体积为V，溶质摩尔质量为M，求溶质的

物质的量浓度C。【推断：根据C=n(溶质)/V(溶液) ，而n(溶质)=m(溶质)/M(溶质)= ρ V W/M，考

3虑密度ρ的单位g/cm化为g/L，所以有C=1000ρW/M 】

6、一定物质的量浓度溶液的配制

A:配制使用的仪器：托盘天平(固体溶质)、药匙、量筒(液体溶质)、一定容积的容量瓶、烧杯、玻璃棒、

胶头滴管。

B:配制的步骤：①计算溶质的量(若为固体溶质计算所需质量，若为溶液计算所需溶液的体积)②称取(或

量取)③溶解(静置冷却)④转移(注入蒸馏水)⑤洗涤⑥定容⑦摇匀

例如：配制400mL0.1mol/L的Na2CO3溶液：

(1)计算：需无水Na2CO3 5.3 g。

(2)称量：用托盘天平称量无水Na2CO3 5.3 g。

(3)溶解：所需仪器烧杯、玻璃棒。

(4)转移：将烧杯中的溶液沿玻璃棒小心地引流到500mL容量瓶中。

(5)洗涤：溶质溶解后转移至容量瓶时，必须用少量蒸馏水将烧杯及玻璃棒洗涤2—3次，并将洗涤液一

并倒入容量瓶，这是因为烧杯及玻璃棒会粘有少量溶质，只有这样才能尽可能地把溶质全部转移到容量瓶中。

(6)定容：当往容量瓶里加蒸馏水时，距刻度线2-3cm处停止，为避免加水的体积过多，改用胶头滴管加蒸馏水到溶液的凹液面正好与刻度线相切，这个操作叫做定容。

a:不能配制任意体积的一定物质的量浓度的溶液，这是因为容量瓶的容积是固定的，没有任意体积规格的容量瓶。

b:溶液注入容量瓶前需恢复到室温，这是因为溶液温度过高会使溶液体积膨胀影响溶液配制的精确度。 C:用胶头滴管定容后再振荡，出现液面底于刻度线时不要再加水，这是因为振荡时有少量溶液粘在瓶颈上还没完全回流，故液面暂时低于刻度线，若此时又加水会使所配制溶液的浓度偏低。

d:如果加水定容时超出了刻度线，不能将超出部分再吸走，须应重新配制。

(7)摇匀：如果摇匀时不小心洒出几滴，不能再加水至刻度，必须重新配制，这是因为所洒出的几滴溶液中含有溶质，会使所配制溶液的浓度偏低。

篇11：人教版语文新课标学习心得

小学语文新课标学习心得体会

新课标要求全面提高学生的语文素养，要求学生扩大知识面，要求课堂教学中师生互动等，我将根据新的语文能力实践系统，致力于学生语文综合素质的提高，促进语文课程的呈现方式和学生学习方式的转变，对于小学语文教学来说，既要转变教的方式，又要转变学的方式，培养和形成“自主、合作、探究”的学习方式，在这两个转变中，教的方式转变是主要矛盾，教的方式一转变，学的方式也随之转变。学的方式转变可以理性地在课堂中呈现，证明教的方式转变，证明教师新理念的真正树立。把课标学习与教材教法研究结合起来，要钻研新教材，理解和把握新教材，用好新教材，要重视教学反思的研究和收集;要牢记验证课标和检验教材的实验任务。在教学实践中，我将力求主要将采取了以下几点作法以：

1、认真学习新课标，深入领会《语文课程标准》的精神实质，切实转变观念，通过教学任务的完成，全面提高学生的整体语文素养，注重提高学生的语文实践能力，积极倡导，促进学生主动发展的学习方法，拓宽学习和运用的领域，注重联系生活，跨学科的学习和探究式学习，使学生获得现代社会所需要的终身受用的语文能力。

2、弄清教科书与《课程标准》、教科书各教程之间的内在联系，弄清教科书各种编辑设计的意图和着力点，以在备课和教学活动中准确设定教学的重点，找准达到《课程标准》提出的课程目标的落脚点，有效地实施语文教学。

3、在准确把握教科书编辑思想基础上，从本班本校本地的实际出发，根据学生的年龄特征和不同教学内容，创造性地灵活地选择和运用教科书的各种设计，采取合适的教学策略，把读写听说和综合实践活动落到实处，大力改进课堂教学，提倡启发式、讨论式教学，积极开发课堂学习资源和课外学习资源，沟通课堂内外，沟通平行学科，创造性地开展各种活动，增加学生语文实践的机会，让学生在实践中丰富语言积累，掌握学习方法，提高基本技能，接受熏陶感染，养成良好的学习习惯，打下扎实的语文基础;鼓励学生采用各种手段扩大阅读面，增强学生在一切场合学语文用语文的意识，积极参加各种课改活动，促进学生语文素养的整体提高，新的一轮以课程与教材为核心的改革正在逐步展开，这给小学语文教学带来了生机，当然也带来了挑战。

另一点体会是，新课程标准仍然非常注重语文基础知识的学习和掌握，新课程标准对语文基础知识不但有具体的要求，还有量化标准。

我觉得把握新的课程评价标准，有一点最应值得重视，那就是：语文课程评价一定要立足于现代社会要求学生所具备的语文素养上，一手好字，一篇好文章，依然是现代社会所需要的，除了这两点，现代社会要求民要有一定的口语交际能力和运用现代技术搜索，处理信息的能力，基于这些思考，我们就应该做好这方面的评价工作。
