Now, there are 14 such schools in countries all over the world, such as Canada, Hong Kong and Singapore. What makes this school so successful is that they believe education is more than just about grades and studies. Rather, they believe it’s about joining people from all over the world to study and live together in peace. The students not only study hard, but they are also encouraged to support society, even in small ways. They join activities that will improve their creativity, health and even the community they live in. For example, students might be allowed to go on trips to nearby towns to do community work or to go on fun cycling tours. On top of this, the school believes that students should have an understanding of cultures of the world. They learn about the different kinds of food people eat and what is or is not allowed in other cultures. The school also holds a yearly show where students perform something related to the traditions of their own countries. This makes students get together and exchange what they know, such as some traditional dances! Through all this, students in the United World Schools truly learn how to understand and support one another even though they come from different parts of the world. They develop good qualities such as patience and friendliness, and also learn to be proud of their own culture. This helps them to see that the world can be a better and happier place, if we all make the effort to understand one another. ( ) 1. What makes the United World School so successful?

2014年下学期高二年级英语组唐荧霞培优辅差工作总结

2014年下学期高二年级英语组唐荧霞 培优辅差工作总结 这个学期学生们进入高二,即将参加学业水平考试,所以学习压力也增加了。而我所任教的班级一个班两级分化严重,另一个班则整体基础薄弱。为了让学生们能够从容地面对考试,我在培优补差方面付出了很多努力,也有很大收获。现将本学期工作总结如下: 第一,积极转化教学观念。在工作过程中,教师的观念能积极转化,由以前看分数,注重优生的辅导,对潜能生耐心不足,"恨铁不成钢",急功近利的心态转变为能正确看待每一个学生,以培养学生素质的提高为自己工作的重点。在工作过程中能个体分析,群体分析,确立发展目标和措施,找出每个学生的优点,缺点,潜在的优点,缺点,新的生长点.用发展的眼光看自己,分析别人。积极对待学生的每一个闪光点,施以恰如其分的鼓励性评价,使得每一位学生能安心于课堂的学习,把学困生的厌学情绪抑制在一个最低点上。 第二,培养良好的学习习惯。良好的学习习惯对学生的学习非常重要,所以我重在抓良好学习习惯的养成。让学生们坚持每天记12个单词,天天听写。每周背诵一篇短文,每个单元进行一次写作练习。监督学生们做好每天晚自习前的听力练习和阅读训练。 第三,对学困生的每一点进步都给予肯定。对学困生的

每一点进步都给予肯定,并鼓励其继续进取,在优生中树立榜样,给予机会表现,调动学习积极性和成功感。定时检查他们的作业,以使他们养成良好的学习习惯。通过内化教育,学生的学习动机,学习积极性大大地被调动起来,不管是优等生或是后进生,现都能明确自己的学习目的,不是为别人,而是为自己;学习风气较以前有明显的变化。 第四,关注优等生,成为班上领军。优等生是班上中差生学习的表率,前进动力和目标。这些优等生有时也会自满,因为课堂上讲授的知识他们一般都是很轻松、容易就吸收掌握了。对这些学生“吃不饱”的现象,也不能轻视,否则会使他们盲目自大,进而丧失积极的思维和强烈的求知欲望。我就在上课的时候,适当增加一些有难度的内容。对待这部分智力因素突出的学生还让他们做些阅读性强,推理性强的练习,在练习或检测中增加信息量。同时开展内容广泛、形式多样的英语课外活动。课后辅导他们参加学校及校外组织的各项英语比赛活动。他们也取得了较好成绩,进一步增加了他们的兴趣。苏霍姆林斯基说过:“兴趣的源泉在于运用。”通过这些活动可以让学生把所学知识运用于实际,使学生认识了自我,取得了不同程度的成就感,更增添了学习英语的兴趣和乐趣,变“要我学”为“我要学”,进而长久保持其对英语学习的兴趣。 第五,经过一个学期的努力,班级的整体学习氛围良好,

初三英语培优补差计划

初三英语培优补差计划 制定培优补差的计划有利于提升初三英语的总体成绩。接下来是为大家带来的关于初三英语培优补差的计划,希望会给大家带来帮助。 初三英语培优补差计划(一)一,指导思想: 实现我国“科教兴国”的国策,必需从理论上,实践上展开对培养尖子生指导,学困生研究和实验,为了全面提高三年级的英语成果,体现出“尖子生吃好,中等生吃饱,学困生吃了。” 二,具体目标:使优生“吃得饱”,后进生“吃得了”,快者快学,慢者慢学,先慢后快,全面提高。 三,学习情况分析: 优生:学习习惯较好,能认真听讲,思维活跃,勤学好问,善于发现解决问题,对知识的应用能力较强,课堂积极发言,课后和时复习,基本上掌握了一定英语学科的学习方法和学习技巧,有一定的阅读能力。 差生:缺乏学习兴趣和积极性,学习习惯差,上课不认真听讲,经常开小差,对基础知识没有基本的了解和掌握。学习态度不端正,学习态度消极,无所谓的态度突出,没有学习方法,对不懂的知识点,经常不理睬,对知识的应用较差。

四,具体措施: (1)培优措施:加强基础知识与交际运用能力的训练,拓宽知识面,多做习题。对于内宿生的优生,晚上他们都很快完成家庭作业,来办公室主动找老师出习题训练。自已也订了小学英语一点通,里面包括小故事,笑话,写作等,借给优生阅读。对于走读优生,另出培优题训练。单元测试后各选前五名进行对抗赛,拓宽知识面。 (2)差生措施:差生形成是有原因的,社会的,学校的,家庭以和个人的因素,所以要搞清楚,每个后进生形成的原因,然后对症下药。如黄帝扶, 杨绍陆是全宿生,家长很少关注他们的学习,上课不认真,经常开小差,基础知识差,对于这两位努力做到不歧视,多鼓励,耐心细致地协助,上课多留意,下课督促他们和时完成相关作业,必要时降低作业要求。如张琼佳,林笃炫,余嘉凯胆子小,害羞,可以通过课后找他们谈话,了解他们的内心世界,还可以通过作业本方式进行书面交流鼓励。如林智进,陈彦陆,郑楚耀,陈佳茵同学通过课堂上多给他们表示自我的机会,增强他们的自信心,并和时给他们鼓励,其次在课堂上为他们专门设计一些难度较小的题目鼓励他们回答,降低要求,让他们体会到胜利的喜悦,从而增加学习英语的兴趣,增强他们自信心。如苏子洁,谢辉彬,郑立盛同学,可以利用优生的优势,指名让他带一名差生,介绍方法让同学怎样学,并教他们读课文,读单词,激起他们的学习兴趣。 对于这些差生课后还要多督促他们做到每天把新学的课文,单词读出来,利用黄昏放学后辅导他们读,早读时带读,对于走读书和家
