第三篇：高二英语下学期期末教学工作总结
高二英语下学期期末教学工作总结
本学期仍然担任文科普通班高二（3）的英语教学工作。在教学过程中结合班级学生的实际情况，对教材进行筛选和整合，在集体精心备课、听课和互评以及积极进行阶段性诊断教学方法的基础上，完成了本学期的英语教学任务。现将本学期的工作情况作如下总结：
一、认真钻研教材，继续探索英语教学模式，努力提高课堂教学质量
教学中努力探索以学生为中心，教师为主导的教学模式。运用视听媒体，采用听说法、讨论法、表演等方式调动学生积极性。注意引导学生积极思考，注重知识的归纳和总结，加强学法指导。例如：如何记单词，课文朗读技巧，对话、叙述原则等。学生的学习效率得到了提高。在语言教学中注意文化知识的渗透。根据教学内容介绍了英美国家的历史地理、风情习俗和有关文学常识。
二、关注学生情感，创造民主、和谐的教学气氛。
1、学生只有对自己、对英语及其文化有积极的情态，才能保持英语学习的动力并取得成绩，刻板的情态，不仅会影响英语学习的效果，还会影响其它发展，情态是学好英语的重要因素，因此我努力创造宽松民主、和谐的教学空间，做到： 尊重每个学生，积极鼓励他们在学习中的尝试，保护他们的自尊心和积极性。
2、把英语教学与情态有机地结合起来，创造各种合作学习的活动，促进学生互相学习，互相帮助，体验成就感，发展合作精神。
3、关注学习有困难的或性格内向的学习，尽可能地为他们创造语言的机会。
4、建立融洽、民主的师生交流渠道，经常和学生一起反思学习过程和学习效果，互相鼓励和帮助，做到教学相关。
三、加强对学生学习策略的指导，让他们在学习和适用的过程中逐步学会如何学习做到：
1、积极创造条件，让学生参与到阶段性学习目标，以及实现目标的方法。
2、引导学生结合语境，采用推测、查阅和协调的方法进行学习。
3、引导学生在学习过程中，进行自我评价，并根据需要调整自己的学习目标和学习策略。
新课程改革不是纸上谈兵，必须要与实践相结合，必须努力学习，积极进取，积极参与课程改革，在课改中不断学习，不断实践，不断反思，愿与新课程共同成长。
4、自我提高方面
在思想方面，坚持以新课程标准倡导的理念为指导，不断学习先进的教育教学理论，更新自己的教育观念，积极参加校本培训和各种网上培训课程，不断提高自身的思想觉悟。在工作之余，我认真阅读各类教育教学著作，杂志和刊物，总结自身教学。课后我积极参与听课、评课，虚心向同行学习教学方法，博采众长，提高教学水平。
再回首，高二已经结束。所任教班级学生的英语学习兴趣及能力都有所提高。自己也积极与组里的老师一起共编写成适合本校学生的《零起点英语教程》。全学期自己出满勤，一切以教学为重，即使自己在这个学期肾积水住院一周也不请假，坚持一面住院打针，打完针回学校给学生上课并超额完成教学任务！本人相信，一份耕耘，一份收获。教学工作苦乐相伴，我将一直以“勤学、善思、真抓、实干”为准则，一如既往，再接再励，继续做好培优扶中和辅差工作，把自己的教学工作做到扎实有效。

高二生物下学期期末试题及答案
第五篇：高二下学期期末总结
高二下学期期末总结
匆匆，太匆匆。每到期末都会发出这种感叹。这个学期过完，高中就度过了2/3了。自己16了，也快成年了。上了大学，就真的成年了，回想一下，这一年里我又收获了什么呢？
首先，从心理上讲，我感觉我又成熟了一些。开始对以后有一些想法了，也逐渐想着让自己干些什么事了，虽然自己有时候不能克制住自己。在成熟的过程中也仍有一种不成熟，想要改变却并未实现的地方。从以前的打球不注意时间到现在的客服自己的哪一点欲望；从以前的自己解决问题到现在的学会问老师、问同学；从以前的对生活的漠不关心到现在的积极面对……我发现自己在一分一秒地变变成熟，以前看以来很热衷的东西在眼中已变成了幼稚的代名词。是的，我长大了。开始懂得很多东西，开始知道有些东西该怎么看清，也许现在的我能够离开自己主观的意愿，站在一个旁观者的角度来思考一下，有些事我做得对还是错，有些话我到底该不该说……
当生活上的一些困难一直困扰着我是，我会感到有些丧气，甚至有些怨恨自己。先天的影响是无法改变的，但是有一个很重要的原因，即后天形成的习惯。我越来越认为习惯对人的影响是非常之大的。曾经当自己犹豫、放弃一些事情时为自己开脱，认为这只是一件小事，以后要真遇到什么的话自己会超凡脱俗、一鸣惊人的。其实不然，没有量的积累，那里会有质的飞跃呢？所以习惯要在每一件事上培养、改良。这一点早就知道，但到现在才有了一些领会。然而这又是一个艰苦的过程，变革永远是困难的，常常会出现半途而废周而复始的情况。关键是当陷入困境之时，阻力会变得异常的大，如何保持住自己的本心不动摇是很难的。具体的方法我至今都没有找到，只希望以前的“周而复始”作为量的积累，让我在以后的生活中得到质的飞跃。到了什么时候我能够在困境中保持冷静，在诱惑面前保持清醒，在困难面前勇敢地正视它，那就说明我真正地做到了自己“质”的飞跃。其次，学习上。就我个人相比而言，高二的我比高一的我学习更努力了一些。
或许是“知耻而后勇”吧！高一过了一年，高二终于有所醒悟了吧！但这种醒悟只能算是一种“微醒”，至于能不能真正醒来还有很长的路要走。自己现在还很容易就受到外界很大的干扰，这也如前面所言，习惯问题，也许解决了这个问题之后，我就能够真的得到自己所想要的东西了吧！^_^
