高三化学教学总结个人篇一
怎样着手进行化学总复习,复习的目的和任务是什么?这是刚刚进入高三的同学所面临的第一个问题,也是教师在高三化学教学过程中所面临的第一个问题,更是作为新高三老师的我的一个大问题。要解决好这个问题,就必须对一些信息进行研究,从中领会出潜在的导向作用,看准复习方向,为完成复习任务奠定基础。
1.研究全国及福建省高考化学试题。纵观每年的高考化学试题,可以发现其突出的特点之一是它的连续性和稳定性,始终保持稳中有变的原则。只要根据近几年来全国或者本省高考形式,重点研究一下近几年的高考试题,就能发现它们的一些共同特点,如试卷的结构、试题类型、考查的方式和能力要求等,因此开学初我们共同研究了十年高考,把握命题方向及命题特点,从而理清复习的思路,制定相应的复习计划。作为福建省新课程的第二届,研究去年的高考的特点尤显得重要
2.关注新教材和新课程的变化。与以往教材、课程标准相比较,现在使用的新版教材发生了很大的变化,如内容的调整,实验比重的加大,知识的传授过程渗透了思想和方法,增加了研究性学习内容、新科技和化学史等阅读材料。很显然,这些变化将体现在高考命题中,熟悉新教材和新课程标准的这些变化,将有利于把握复习的方向和深难度,有利于增强复习的目的性。
3.熟悉考试大纲和考试说明。考试说明是高考的依据,是化学复习的“总纲”,不仅要读,而且要深入研究,尤其是考纲中变化的地方,以便明确高考的命题指导思想、考查内容、试题类型、深难度和比例以及考查能力的层次要求等。不仅如此,在整个复习过程中要不断阅读,进一步增强目的性,随时调整复习的方向。
4.合理利用其他资源。除了高考试题、考试说明、教材、课程标准、化学教学基本要求外,获得信息的途径、方法还很多,如各种专业杂志、名校试题、网络信息等。但是,这些资料的使用必须合理,这样对教师提出了很高的要求,老师自身必须投入题海,然后筛选训练题和资料,备课组内老师资源共享,进度统一,皆以广泛收集信息为主要目的,以免干扰复习、浪费时间。
进入高三化学教学,很容易走进总复习的怪圈:“迷恋”复习资料,陷入“题海”。虽然投入了大量的时间和精力,但收效甚微,效果不佳。对此,高三化学教学过程中必须保持清醒的头脑,努力处理好下面几种关系。
1.教材和复习资料的关系。教材是化学总复习的根本,它的作用是任何资料都无法替代的。在化学总复习中的抓纲务本就是指复习以考试说明作指导,以教材为主体,通过复习,使中学化学知识系统化、结构化、网络化,并在教材基础上进行拓宽和加深,而复习资料的作用则是为这种目的服务,决不能本末倒置,以复习资料代替教材。我们以《博学精练》作为主要复习书,在复习的过程中注重随时回归教材,找到知识在教材中的落脚点和延伸点,不断完善和深化中学化学知识。因此我们要求学生在复习下一节之前完成基础知识部分,弄清自己的不足,上课做到有的放失。
2.重视基础和培养能力的关系。基础和能力是相辅相成的,没有基础,能力就缺少了扎根的土壤。正因为如此,化学总复习的首要任务之一是全面系统地复习中学化学知识和技能。通常中学化学知识和技能分成五大块:化学基本概念和基本理论、元素及其化合物、基础有机化学、化学实验和化学计算。如对化学概念、理论的复习,要弄清实质和应用范围,对重点知识如物质的组成、结构、性质、变化等要反复记忆不断深化,对元素及其化合物等规律性较强的知识,则应在化学理论的指导下,进行总结、归纳,使中学化学知识和技能结构化、规律化,从而做到在需要时易于联系和提取应用。同时注意规范化学用语的使用(如化学反应方程式、离子方程式、电极反应式、电离方程式以及化学式、结构式、电子式等),规范语言文字的表达能力,力争使基础知识和技能一一过关。
3.化学学科和其他学科知识的关系。化学是一门重要的基础自然科学,与数学、物理、生物乃至社会发展各方面都有密切的联系,不仅在知识上有相互融合和渗透,而且分析处理问题的方法也有相同、相似或者可以相互借鉴的地方。这一点不仅在教材中有所体现,而且在近几年的高考试题中也有充分的体现,如化学与社会生产、生活实际,化学与新科技、新发现等相互联系的试题有增加的趋势。因此,在复习中可以化学知识为主干,找出化学与其他学科的结合点、交叉点,并以此为基础向其他学科领域延伸、扩散,实现从单一学科知识和能力向综合科的综合知识和能力转化,促进综合素质的提高,切实培养解决化学与社会等实际问题的能力。
4.练习量和复习效率的关系。练习是化学总复习的重要组成部分,是运用知识解决问题的再学习、再认识过程,也是促进知识迁移、训练思维、提高分析问题和解决问题能力的重要途径,但练习量必须合理,以保证质量为前提,避免简单的机械重复和陷入“题海”。通过练习要达到强化记忆、熟练地掌握知识、找出存在的问题、弥补薄弱环节、扩大知识的应用范围和提高能力的目的,从而提高复习效率。
化学总复习的范围是有限的,要想在有限的时间里达到最佳复习效果,只能采用科学的方法,在教师的教学中、学生的学习过程中都必须开动脑筋,多思善想。在化学教学过程中采用分层教学,有平时的正常面上的教学,有优秀生的提高,和学习有困难学生的加强基础等不同的形式。
1.精读教材,字斟句酌。系统复习,自始至终都应以教材为本,注意知识的全面性、重点性、精确性、联系性和应用性。对中学(初、高中)化学知识和技能都要一一复习到位;对教材中的关键性知识(我们常说的考点),进行反复阅读、深刻理解,以点带面形成知识结构;对化学知识的理解、使用和描述要科学、准确和全面,如规范地使用化学用语,正确、全面地表达实验现象和操作要点等(尤其适合中等以下的学生,利用年级组统一安排的基础加强课时间);对知识点之间的相互关系及其前因后果。如与离子反应有关的知识有离子反应方程式的书写和正误判断、离子共存问题、离子浓度大小比较、离子的检验和推断、溶液的导电性变化等。应用性是指通过复习要学会运用知识解决实际问题的方法,如元素周期律、周期表涵盖的内容相当丰富,可以进行元素位、构、性相互推断,预测未知元素的性质,比较各种性质的强弱等。此外,要重视对化学实验内容的复习(包括教材中的演示实验和课本后的分组实验),而且尽可能地亲自动手操作,通过这些典型实验,深入理解化学实验原理(反应原理、装置原理、操作原理)、实验方法的设计、实验结果的处理等,切实提高实验能力。
2.学会反思,提高能力。能力的培养是化学总复习的另一个重要任务,它通常包括观察能力、思维能力、实验能力和计算能力,其中思维能力是能力的核心。值得注意的是,能力的提高并不是一天就能办得到的,要经过长期的积累和有意识的培养。因此,在复习过程中,特别是做题、单元考试、大型考试后,要常回头看一看,停下来想一想,我们的复习有没有实效,知识和技能是否获得了巩固和深化,分析问题和解决问题的能力是否得到了提高。要善于从学生的实际出发,有针对性地进行知识复习和解题训练,而不是做完练习题简单地对对答案就万事大吉了,而是进一步思考:该题考查了什么内容,其本质特征是什么,还有其他更好的解法吗?对典型习题、代表性习题更要多下功夫,不仅一题一得,更要一题多得,既能促使知识得到不断地弥补、完善,又能举一反三,从方法上领会解题过程中的审题、破题、答题的方式和奥秘等,以此培养良好的思维品质(严密性、敏捷性、深刻性、创造性和广阔性)。长期坚持,就能化平凡为神奇:能掌握化学知识及其运用的内在规律和联系,善于抓住关键,灵活地解决化学问题;能驾御化学问题的全貌,抓联系、作比较、会归纳、能延伸;能另辟蹊径、不拘一格地解决实际问题。
健康向上、勇于进取、自信自强的积极心态是搞好复习的重要保证,也是高考成功的关键。而积极的心态有赖于平时的不断调整和锤炼。
1.正确对待考试。在高三复习过程中,考试是频繁的。由于受高考一试定终身的负面影响,许多同学对考试成绩的重视程度远远超过了考试本身所起的作用,把平时的每一次考试都是练兵的绝好机会,都能够暴露学生存在的问题,有利于在后续复习中进行针对性的查漏补缺,总结经验教训,以便学生在高考中不犯错误或少犯错误,所以既不能因一时失误或遇到困难而气馁,也不能因成绩进步而沾沾自喜。
2.合理安排学习的时间。复习不是一朝一夕的事情,我们的身体就像一台精密的仪器,决不能超负荷使用,相反地,必须加以维修和保养,这样,它才能经久耐用。因此,我们要动静结合,既要勤奋学习,也要学会放松、休息、锻炼,只有劳逸结合、生活得有规律,才能轻松自如地渡过难关。这就是所谓的一张一弛的文武之道。
3.创设良好的学习心理环境。人的心理和行为受各种环境因素的影响,对大多数高三学生来说影响最大的恐怕就是升学压力和竞争压力了,如果处理不好就可能带来消极影响,这对复习是极为不利的。因此,在化学教学过程中要使学生正确地认识自己,从自己的基础和实际出发,扎扎实实地复习;愉快地接纳自己,充分肯定自己的进步,找出存在的问题及时弥补;自觉地控制自己,以明确的目标、良好的意志力调节自己,变压力为动力,全面提高自己的素质。
五、存在的不足和问题
1、作为一个新高三老师,我的教学经验不足,对教材的把握和知识内容体系的“度”的控制,以及教学进度的掌握均存在一定的缺憾。导致学生基础知识遗忘率高,教师教的辛苦学生学的也累。
2、练习的训练量还是不足,由于生源问题,基础差的学生多,教学进度虽然不滞后,但是要做到段段清,节节过关就显有点吃力。
总之,化学总复习要为高考做好知识准备和精神准备,要有目标、有计划、讲究方法、注重落实,千方百计地提高化学总复习的效益。我们高三化学备课组始终坚守原则,希望圆满完成学校交给的任务。

高三化学教学总结个人篇三
本期我担任高三281、290两班化学教学工作及高三化学备课组长。高三化学总复习是中学化学学习非常重要的时期,也是巩固基础、优化思维、提高能力的重要阶段,高三化学总复习的效果将直接影响高考成绩。为了今后更好的工作我把本学期的教学工作总结如下。
怎样着手进行化学总复习,复习的目的和任务是什么?这是刚刚进入高三的同学所面临的第一个问题,也是教师在高三化学教学过程中所面临的第一个问题。要解决好这个问题,就必须对一些信息进行研究,从中领会出潜在的导向作用,看准复习方向,为完成复习任务奠定基础。
1.研究高考化学试题。纵观每年的高考化学试题,可以发现其突出的特点之一是它的连续性和稳定性,始终保持稳中有变的原则。因此我与其他高三化学教师仔细分析了近几年来课改区的高考试题,结合历年来湖南高考化学试题的特点,如对比试卷的结构、试题类型、考查的方式和能力要求等,从而理清复习的思路,制定相应的'复习计划。因此在我校暑期举行的教师业务考试当中我与其他同备课组的化学老师全部获得优异成绩。
2.关注新教材和新课程标准的变化。熟悉新教材和新课程标准的变化,将有利于把握复习的方向和深难度,有利于增强复习的目的性。
3.熟悉考试大纲。考纲是高考的依据,是化学复习的“总纲”,不仅要读,而且要深入研究,以便明确高考的命题指导思想、考查内容、试题类型、深难度和比例以及考查能力的层次要求等。因此在12月我省考试大纲公布之后,我与备课组老师仔细研究,并准备在今后教学中不断阅读,进一步增强目的性,随时调整复习的方向。
进入高三化学教学,很容易走进总复习的怪圈:“迷恋”复习资料,陷入“题海”。虽然投入了大量的时间和精力,但收效甚微,效果不佳。对此,高三化学教学过程中必须保持清醒的头脑,努力处理好下面几种关系。
1.教材和复习资料的关系。教材是化学总复习的根本,它的作用是任何资料都无法替代的。在化学总复习中的抓纲务本就是指复习以考试说明作指导,以教材为主体,通过复习,使中学化学知识系统化、结构化、网络化,并在教材基础上进行拓宽和加深,而复习资料的作用则是为这种目的服务,决不能本末倒置,以复习资料代替教材。通常的做法是精选一套复习资料(我校以《名师导学》)作为主要参考书,供整理知识、练习使用,在复习的过程中应随时回归教材,找到知识在教材中的落脚点和延伸点,不断完善和深化中学化学知识。
2.重视基础和培养能力的关系。基础和能力是相辅相成的,没有基础,能力就缺少了扎根的土壤。通常中学化学知识和技能分成五大块:化学基本概念和基本理论、元素及其化合物、有机化学、化学实验和化学计算。如对化学概念、理论的复习,要弄清实质和应用范围,对重点知识如物质的组成、结构、性质、变化等要反复记忆不断深化,对元素及其化合物等规律性较强的知识,则应在化学理论的指导下,进行总结、归纳,使中学化学知识和技能结构化、规律化,从而做到在需要时易于联系和提取应用。同时注意规范化学用语的使用(如化学反应方程式、离子方程式、电极反应式、电离方程式以及化学式、结构式、电子式等),规范语言文字的表达能力,力争使基础知识和技能一一过手。
3.练习量和复习效率的关系。练习是化学总复习的重要组成部分,是运用知识解决问题的再学习、再认识过程,也是促进知识迁移、训练思维、提高分析问题和解决问题能力的重要途径,但练习量必须合理,以保证质量为前提,避免简单的机械重复和陷入“题海”。因此我与同备课组老师基本每周都精心准备了一张周练卷;每单元准备了单元过关测试卷。
化学总复习的范围是有限的,要想在有限的时间里达到最佳复习效果,只能采用科学的方法,在教师的教学中、学生的学习过程中都必须开动脑筋,多思善想。
1.精读教材,字斟句酌。
系统复习,自始至终都应以教材为本,注意知识的全面性、重点性、精确性、联系性和应用性。对中学(初、高中)化学知识和技能都要一一复习到位;对教材中的关键性知识(我们常说的考点),进行反复阅读、深刻理解,以点带面形成知识结构;对化学知识的理解、使用和描述要科学、准确和全面,如规范地使用化学用语,正确、全面地表达实验现象和操作要点等(尤其适合中等以下的学生);对知识点之间的相互关系及其前因后果。如与离子反应有关的知识有离子反应方程式的书写和正误判断、离子共存问题、离子浓度大小比较、离子的检验和推断、溶液的导电性变化等。应用性是指通过复习要学会运用知识解决实际问题的方法,如元素周期律、周期表涵盖的内容相当丰富,可以进行元素位、构、性相互推断,预测未知元素的性质,比较各种性质的强弱等。
2.学会反思,提高能力。
能力的培养是化学总复习的另一个重要任务,它通常包括观察能力、思维能力、实验能力和计算能力,其中思维能力是能力的核心。要善于从学生的实际出发,有针对性地进行知识复习和解题训练,而不是做完练习题简单地对对答案就万事大吉了,而是进一步思考:该题考查了什么内容,其本质特征是什么,还有其他更好的解法吗?对典型习题、代表性习题更要多下功夫,不仅一题一得,更要一题多得,既能促使知识得到不断地弥补、完善,又能举一反三,从方法上领会解题过程中的审题、破题、答题的方式和奥秘等,以此培养良好的思维品质。
本期我所教班级中有完全针对文化高考的281班和具有特色的体育特长290班,面对学生情况完全不相同的两班,因此在化学教学过程中采用分层教学,有平时的正常面上的教学,有优秀生的提高,和学习有困难学生的加强基础等不同的形式。
1、在备课中我不但按常规做好课前、课中、课后的各项工作,更是认真备学生,积极在课前、课后了解学生的知识结构,个性发展及思想情绪,尽可能的在课堂教学真正体现“教师为主导,学生为主体”的教学思想,注意创设不同的情境,诱发不同层次学生的认知需求和创新欲望,使不同层次的学生都能从情感、思维和行为上主动参与学习,使学生都能学有所得,不断提高。
2、 课后,为不同层次的学生进行相应的辅导,以满足不同层次的学生的需求,避免了
一刀切的弊端,同时加大了后进生的辅导力度。对后进生的辅导,并不限于学习知识性的辅导,更重要的是学习思想与方法的辅导,通过各种途径激发他们的求知欲和上进心,让他们意识到学习并不是一项任务,也不是一件痛苦的事情,而是充满乐趣的,从而自觉的把身心投放到学习中去。
3、在每次各种练习中,我针对两班不同情况都进行了不同层次的命题,让学生真正能学有所得,练有所获。
一分耕耘,一分收获。本学期各种测评我所带班级均在同年级中名列前茅,同时我还积极参与教研教改中,在代表我市参加全省课堂教学竞赛中以全省第二名获得省一等奖。当然,不足之处也同时存在,例如因为课时较多,没有更多地运用现代化教学技术,而使某些教学内容没能更好地诠释,这都是今后需要改进之处。

高三化学教学总结个人篇五
本学期高考化学复习做到以下几点:
1、研究《考试大纲》和《考试说明》,选择复习内容和深广度。
2、夯实基础知识和基本技能,掌握基本方法。
3、优化课堂教学,针对一轮复习的薄弱环节适时开展二轮专题复习,提高复习效率。
4、精选试题,科学训练,优化讲评过程。
5、加强合作,充分发挥备课组的集体力量,开展问题导学教学模式的研究。
6、坚持每日一小卷,每卷七道选择,坚持了64卷。每天一早将试卷下发,学生利用课余时间完成核对答案,不会的当天要问会了。这项工作其实就坚持了一学期,虽然老师很辛苦,答疑量比以往多出很多,每一个中午和课间办公室都是人满为患。但想想做到最后同学们真的收获很多,以往选择对4个是一大关,到今年相当多的人能对5个甚至6个。真是应了那句话,百炼成钢!
7、做好专题复习,在二模以后分大题专项练习,题的来源是近三年的十二校联考试题和近三年的高考真题。先利用双周四早自习的时间进行第七题专练,然后花了一周时间进行第十题专练,随后是第八题专练(有机)、第九题专练(实验)。第九题专练之前我们还安排了一个无机工艺流程流程专题复习,总结出“主线主产物,分支副产物,回头是循环”的规律,还明确了物质制备实验目的一定是要“多快好省地生产高纯度的产品”。这些铺垫对后期实验专题试题的顺利开展起到了很好的导向作用。也直到做完这四个专题以后,学生对化学考试才能真正做到心中有数,驾轻就熟!
进入高三,除了开展每周一次的教研组会议以外,还组织每周一次以上的备课组活动,总结上一周教学完成情况,分析复习过程中的优缺点,交流学生反馈的各种问题,交换对总复习教学的个人看法。提出下周教学方案,包括复习方法、课时安排、作业处理、训练计划,开展有效教学研究。特别是在专题复习时,大家一起揣摩和研究,努力做到备教材、备习题、备教学方法和备考试大纲。在备课过程中,备课组成员中由一人作专题发言,其它成员作补充,取长补短,相互切磋,资源共享,防止偏题、怪题和难题,发挥集体的智慧和力量。

高三化学教学总结个人篇七
面对自06年以来高考化学试题难度逐年提高的现实,结合所带班级学生的实际情况,按照年级组的统一部署,组织了一年来教学工作,现总结如下:
化学虽属于理科,但又不同于数学和物理,它研究的是物质的个性,知识显得比较杂乱,而且化学教材大多属于叙事式写法,例题少、公式少,但高考中的计算却在逐年增多,同时,该学科的学科特点明显,化学用语多。针对这些,我从一开始就把打基础,强化学科能力放在了第一位。
我结合多年从事高三教学的经验和高考试发展的实际情况,从题型、方法和知识等角度出发,将高中化学的全部内容整合成二十三个专题进行复习。在每个专题的复习中,先引导学生进行知识梳理,再提炼出知识要点和题型方法,然后,通过例题分析,引导学生将悬空的知识和技能再次细化,此后让学生练习感悟,最后引导学生归纳总结,形成每一专题的知识、题型和方法。在整体内容的安排上,我将工具性知识、理论性知识靠前安排,而将载体性知识、自成体系的知识靠后安排。通过这一流程的复习,学生不再感觉到化学是那么凌乱,面对题目的时候,不再感觉到茫然。为学生构建起扎实的完整知识体系。
课堂仍然是复习的主阵地,丢了课堂就等于丢了复习。抓课堂是实施有效复习的关键。这对我们教师提出了很高的要求,关于这一问题,我在前面已经谈过了。我在复习中狠抓限时练习和综合考练。我将作业根据题量和难度,让学生限定时间来完成。同时,我们认真命制或选择了年级组织的十五次考试所需的试题,在第二学期,我还自己选择命制了十二套化学试题,利用晚自习等时间进行检测。这些做法,使教学得到了充分的落实。
09届高考已经结束,对化学复习仍有一些问题需要探讨:
1、知识复习中,如何构建知识框架和体系,再由此上升为学生的解题能力?
2、例题、习题的选择讲解,要精心设计,要有梯度,要有逻辑;
3、要注意提升学生的信心和兴趣,要建立和谐的师生关系,以促进课堂教学的效果;
4、要强化学科规范,要强化化学计算能力的培养;
5、考前一周,最好能将重点知识、重要题型、重要方法引导学生回顾一下;
6、综合成绩的好坏对学生的高考总分至关重要,建议从十二月开始每周能给综合科目排一次大练习。
7、在我省明年高考方案没有出台之前,要认真研读新课标下的高考试题以明确组织复习的方向。
以上如有不妥,敬请批评指证。
谢谢大家!

高三化学教学总结个人篇九
本学期我担任高三4、6两个班的化学教学工作。现将一学期的工作总结如下:
高考化学试题具有连续性和稳定性,始终保持稳中有变的原则。因此开学初在备课组长的引领下认真研究考纲、考试说明,理清复习的思路,制定相应的详细复习计划。考试说明是高考的依据,是化学复习的“总纲”,不仅要读,而且要深入研究,尤其是考纲中变化的地方,不仅如此,在整个复习过程中我不断阅读,进一步增强目的性,随时调整复习的方向。
我们高三备课组统一计划:第一阶段的基础复习,稳扎稳打,打好基础。这阶段复习主要以《必修1》、《必修2》、《化学反应原理》、《有机化学》基本教材为线索,《金版新学案》为教辅,进行系统的复习。考纲规定的考点,近几年高考反映的重点考点,怎样帮助学生理解这些知识点的有关内容,以及各知识点之间的联系,是第一阶段复习要解决的重要问题。在复习课的教学过程中,我感觉不能简单的将知识点进行堆积,师生应互动,引导学生将头脑中散乱的知识条理化、系统化、规律化,将零星的知识“点”梳理成知识“线”,并编织成知识“网”。同时还要将化学知识提炼升华,形成牢固的知识框架结构和学科知识体系。这样才能使学生所学的知识融会贯通,消除知识上的盲点,拓展知识的生长点,达到启迪思维,开发智力,将知识内化为能力的目的。
(1)回归课本,精读教材,字斟句酌。系统复习,自始至终都应以教材为本,回归教材,注意知识的全面性、重点性、精确性、联系性和应用性。对中学化学知识和技能都要一一复习到位;对教材中的关键性知识,进行反复阅读、深刻理解,以点带面形成知识结构;对化学知识的理解、使用和描述要科学、准确和全面,如规范地使用化学用语,正确、全面地表达实验现象和操作要点等对知识点之间的相互关系及其前因后果。如与离子反应有关的知识有离子反应方程式的书写和正误判断、离子共存问题、离子浓度大小比较、离子的检验和推断、溶液的导电性变化等。应用性是指通过复习要学会运用知识解决实际问题的方法,如元素周期律、周期表涵盖的内容相当丰富,可以进行元素位、构、性相互推断,预测未知元素的性质,比较各种性质的强弱等。此外,要重视对化学实验内容的复习,而且尽可能地亲自动手操作,通过这些典型实验,深入理解化学实验原理、实验方法的设计、实验结果的处理等,切实提高实验能力。
高三化学教学总结个人篇十
这学年我担任高三(2)、(3)、(4)班的化学教学工作,随着高考一落幕,我们的工作也就此告一段落。结合今年高考试卷我认真回顾了这一学年来的教学工作,因为是第一届带高三,算不上经验,就此谈点自己的心得。
今年的高考化学试卷考查的内容多为学生熟悉的“老面孔”,有利于学生发挥,但总体上说试题还是体现了一定的区分度。相比省市质检,本次高考试题有一定的灵活性,而难度明显提高,主要表现在试题涉及的计算较多、实验较复杂。
1.一进入高三,为了使学生对高三化学总复习有良好的效果,并且顺利度过这一重要的时期,我们备课组参考以往实施新课程高考的海南、山东、宁夏、江苏等省市的高考试卷,同时关注新教材和新课程标准的变化,并认真研究考试说明,先对高三化学教学制定了详细的计划,根据高三各个不同时期使用不同的教学策略和训练方式。因此一开始我们的复习方向性就把握的很好。
2.抓好第一阶段的基础复习,抓好“双基
”落实,打好学科基础。这阶段复习主要以《必修1》、《必修2》、《化学反应原理》基本教材为线索,《世纪金榜》为教辅,进行系统的复习。考纲规定的考点,近几年高考反映的重点考点,怎样帮助学生理解这些知识点的有关内容,以及各知识点之间的联系,是第一阶段复习要解决的重要问题。在复习课的教学过程中,教师不能简单的将知识点进行堆积,应师生互动,引导学生将头脑中散乱的知识条理化、系统化、规律化,将零星的知识“点”梳理成知识“线”,并编织成知识“网”。同时还要将化学知识提炼升华,形成牢固的知识框架结构和学科知识体系。这样才能使学生所学的知识融会贯通,消除知识上的盲点,拓展知识的生长点,达到启迪思维,开发智力,将知识内化为能力的目的。
3.在基础复习过关后进行学科第二阶段的专题复习。这阶段我们还是用《世纪金榜》第二轮复习资料,以能力带双基,以培养学生的各种能力为主。在知识上以学科内综合为主,适当增加理、化、生三科的综合。可按照基本概念、基础理论、元素化合物、有机化学基础、物质结构和性质、实验、计算七大块设置专题,同时还针对高考重点、热点,针对学生在复习中的薄弱环节设置专题练习,这是查漏补缺、深化知识的一个重要方面。
4.5月份,以综合训练和查漏补缺主要形式。在这一阶段,要引导学生反思总结。反思,可以深化对知识和问题的理解,促进知识的迁移和延伸;反思可以形成思维链,促进对知识和问题的探究,寻找解题的方法和策略。而且要引导学生严格纠错,以达到规范、正确解题的目的。在这一阶段,学生的适应性得以加强,这样,学生无论知识性失误还是心理性失误都会大大减小。
1.我们是首届使用新教材,对教材的把握和知识内容体系的“度”的控制,以及教学进度的掌握均存在一定的缺憾。导致学生基础知识遗忘率高,教师教的辛苦学生学的也累。
2.学生动手实践的机会的缺乏。新教材实验内容和实验要求很高,尤其高三还有大型探究实验,由于学校实验条件和课时还达不到新课程改革要求。尽管老师和实验员想尽办法,动足脑筋,但还是遗憾多多。很多很多的实验仪器都是学生在考卷上而不是在实验室认识的,很多很多的实验学生也只能在脑海里演绎它的过程。
3.对于平行班的学生训练量还是要多,但是如果稍许留心一下就可以发现所有的这些题目都只是建立在学生的那本相比起来不能算厚的笔记本的理论知识上面,并且题做到最后每每都能碰到做过不止一遍的题目,这更说明了题目是逃不出一定的理论知识的范畴的。而学生在一味做题的同时却容易渐渐的远离理论知识的本质,钻进本无必要多花心思的题目里面去,结果往往越陷越深,无法自拔!因此从这方面来讲只重视解题而不重视思路的梳理无疑是化学教育中的一个重大缺失。
总之,化学总复习要为高考做好知识准备和精神准备,要有目标、有计划、讲究方法、注重落实,千方百计地提高化学总复习的效益。

高三化学教学总结个人篇十二
高三化学总复习是中学化学学习非常重要的时期,也是巩固基础、优化思维、提高能力的重要阶段,高三化学总复习的效果将直接影响高考成绩。为了使学生对高三化学总复习有良好的效果,并且顺利度过这一重要的时期,为此我们高三化学备课组一学期来对高三化学教学有详细的计划,注重教学过程,常总结和反思,根据高三各个不同时期使用不同的教学策略和训练方式。
怎样着手进行化学总复习,复习的目的和任务是什么?这是刚刚进入高三的同学所面临的第一个问题,也是教师在高三化学教学过程当中所面临的第一个问题。要解决好这个问题,就必须对一些信息进行研究,从中领会出潜在的导向作用,看准复习方向,为完成复习任务奠定基础。
纵观每年的高考化学试题,可以发现其突出的特点之一是它的连续性和稳定性,始终保持稳中有变的原则。只要根据近几年来全国高考形式,重点研究一下全国近几年的高考试题,就能发现它们的一些共同特点,如试卷的结构、试题类型、考查的方式和能力要求等,因此开学初我们共同研究了十年高考,把握命题方向及命题特点,从而理清复习的思路,制定相应的复习计划。
与以往教材、课程标准相比较,现在使用的新版教材和课程标准已经发生了很大的变化,如内容的调整,实验比重的加大,知识的传授过程渗透了科学思想和科学方法,增加了研究性学习内容和新科技、化学史等阅读材料。很显然,这些变化将体现在高考命题中,熟悉新教材和新课程标准的这些变化,将有利于把握复习的方向和深难度,有利于增强复习的目的性。
考试说明是高考的依据,是化学复习的“总纲”,不仅要读,而且要深入研究,尤其是考纲中变化的地方,以便明确高考的命题指导思想、考查内容、试题类型、深难度和比例以及考查能力的层次要求等。不仅如此,在整个复习过程当中要不断阅读,进一步增强目的性,随时调整复习的方向。
除了高考试题、考试说明、教材、课程标准、化学教学基本要求外,获得信息的途径、方法还很多,如各种专业杂志、名校试题、网络信息等。但是,这些资料的使用必须合理,这样对教师提出了很高的要求,老师自身必须投入题海,然后筛选训练题和资料,备课组内老师资源共享,进度统一,皆以广泛收集信息为主要目的,以免干扰复习、浪费时间。
进入高三化学教学,很容易走进总复习的怪圈:“迷恋”复习资料,陷入“题海”。虽然投入了大量的时间和精力,但收效甚微,效果不佳。对此,高三化学教学过程当中必须保持清醒的头脑,努力处理好下面几种关系。
教材是化学总复习的根本,它的作用是任何资料都无法替代的。在化学总复习中的抓纲务本就是指复习以考试说明作指导,以教材为主体,通过复习,使中学化学知识系统化、结构化、网络化,并在教材基础上进行拓宽和加深,而复习资料的作用则是为这种目的服务,决不能本末倒置,以复习资料代替教材。我们以《优化探究》作为主要参考书,供整理知识、练习使用,在复习的过程当中应随时回归教材,找到知识在教材中的落脚点和延伸点,不断完善和深化中学化学知识。因此我们要求学生在复习下一节之前完成基础知识部分,弄清自己的不足,上课做到有的放失。
基础和能力是相辅相成的,没有基础,能力就缺少了扎根的土壤。正因为如此,化学总复习的首要任务之一是全面系统地复习中学化学知识和技能。通常中学化学知识和技能分成五大块:化学基本概念和基本理论、元素及其化合物、有机化学、化学实验和化学计算。如对化学概念、理论的复习,要弄清实质和应用范围,对重点知识如物质的组成、结构、性质、变化等要反复记忆不断深化,对元素及其化合物等规律性较强的知识,则应在化学理论的指导下,进行总结、归纳,使中学化学知识和技能结构化、规律化,从而做到在需要时易于联系和提取应用。同时注意规范化学用语的使用(如化学反应方程式、离子方程式、电极反应式、电离方程式以及化学式、结构式、电子式等),规范语言文字的表达能力,力争使基础知识和技能一一过手。
化学是一门重要的基础自然科学,与数学、物理、生物乃至社会发展各方面都有密切的联系,不仅在知识上有相互融合和渗透,而且分析处理问题的方法也有相同、相似或者可以相互借鉴的地方。这一点不仅在教材中有所体现,而且在近几年的高考试题中也有充分的体现,如化学与社会生产、生活实际,化学与新科技、新发现等相互联系的试题有增加的趋势。因此,在复习中可以化学知识为主干,找出化学与其他学科的结合点、交叉点,并以此为基础向其他学科领域延伸、扩散,实现从单一学科知识和能力向综合科的综合知识和能力转化,促进综合素质的提高,切实培养解决化学与社会等实际问题的能力。
