    精编小学教师个人成长心得感悟收获八篇

    一、教育教学方面本学年年初,我就给自己制定了继续把讲台站好、努力把讲台站活的大体目标,进而从备课、上课、课后反思三个环节着手对自己的教学工作进行改进。由于所教学生学习基础、学习习惯差别较大,这三个环节中我都努力做到因材施教,让成绩处于不同层面的学生都能有所进步。作为语文教师,我始终注重培养学生的写作能力,用文如其人的理念来感染和塑造他们的气质及人格。通过努力,我所教的班级语文成绩在年级名列前茅,辅导学生多次在报刊杂志上发表文章,并在多次作文比赛中获奖。

    大班体育《战胜大灰狼》说课稿

    二.教学目标的制定废旧的自行车轮胎看起来并不起眼,但对于孩子的来说却是一件不可多得的宝贝。它的可玩、可创造、可变形、将在活动中带给孩子极大的乐趣。素质教育的重点之一是孩子创新意识和创造能力的培养。在此次活动设计中,我将为孩子们创造各种有趣的情境,利用手中的废旧自行车轮胎,让孩子创想出各种不同的玩胎方式,启发他们的发散性思维,起到“一物多玩”,“一物多用”的效果。在富有创造性的故事情节中,幼儿也同样感受着这样一种熏陶:那就是不管敌人有多可怕,只要我们积极锻炼身体,团结合作,勇敢对“敌”,我们必定会取得最后的胜利。因此,根据器材本身和当今“二期课改”的精神要求,我为此活动制定了以下目标:1.通过尝试自行车轮胎的各种玩法,发展幼儿走、跑、跳、钻爬等基本动作,发展幼儿的想象能力和创造能力。2.让幼儿自定比赛规则和玩法,发挥幼儿主动学习的精神。3.通过激烈的比赛,发挥幼儿的竞争意识及不怕苦、不怕累,勇敢对敌的精神。三.教学活动设计和组织新颖的体育活动设计,对幼儿具有极大的挑战性和吸引力,它能大大地提高幼儿的探索欲望,激发幼儿对活动新形势的喜爱。整个故事情节叙述了小兔如何被大灰狼欺负,如何努力学本领、锻炼身体,最终齐心协力、打败大灰狼的故事。游戏开始部分,小兔自由自在地草地上蹦跳,听到妈妈(有老师扮演)在叫“狼来了”,小兔迅速地跑到房子(轮胎)内抱成一团,尽量不要掉到房子外,以免被大灰狼(由另一幼儿扮演)抓走。当大灰狼走时,小兔又重新回到草地,但狡猾的大灰狼却会每次来悄悄地偷走了他们的一座房子。到下一次狼来袭击时,因为房子数量的逐渐减少,就给小兔增添了躲藏的难度,这就要求小兔要迅速地调整所站的位置,以站下更多的小兔。虽然这只是一个小小的热身游戏,但却在无形中培养了他们关爱他人,团结协作和谦让宽容的精神。

  • 关于农村农民文化生活现状调研报告

    关于农村农民文化生活现状调研报告

    1、文化生活贫乏。通过对89名不同文化程度村民的问卷调查,他们的日常文化生活方式主要有看电视和打牌(含扑克、麻将、字牌等)两种。其中,93%的被调查者表示,看电视是日常最主要的文化生活方式,平均每天看电视的时间在两个小时以上。除了看电视之外,最普遍的就是打牌,一走进农村,闲散无事的农民三五成群玩扑克、打麻将的情况随处可见,而且没有不“带彩”的,其带彩数额一般在1-10元不等,一次牌局的输赢大部分在几十元以上。其他的像棋类、球类之类的活动开展得很少,玩电脑游戏和进行业余文艺创作的人更少,很多35岁以上的人甚至不知道上网是怎样一回事,家庭上网为空白。

    法制宣传日国旗下讲话稿:严以律已,做遵纪守法的好学生

    尊敬的老师、亲爱的同学们:大家早上好!我叫xx,是xx边防派出所的所长,也是一中法制副校长。今天,很高兴又在国旗下为大家上法制课,11月17日和大家一起经历了霞中110周年校庆,一起受到淋浴和熏陶,感受到百年老校散发出的时代活力。今天,非常荣幸和老师、同学们一起探讨一下法律和安全的有关问题。大家知道,12月4日是我国的法制宣传日,本周是法制宣传周。今天我讲话的题目是《严以律已,做遵纪守法的好学生》,内容主要有两个方面,一是坚决摒弃不良习惯,做遵规守法的好学生;二是从我做起,自觉养成良好校园交通习惯。一、坚决摈弃不良习惯,做遵规守法学生。首先,大家要学法知法懂法。俗话说:“没有规矩不成方圆”,自古家有家规,校有校纪,国有国法。只有学习法律知识,才能知道什么是合法,什么是违法,才能分辩是非,识别善恶;只有学法,才能树立民主法制观念,明确公民的权利与义务,才能依法办事,依法维护自身权益。调查表明:中学生中认为法律与我们的生活密切相关的不到一成;认为遇到不法伤害、被敲诈几块钱是小事不必计较的近半。这不能不给我们深刻警示。当学生被敲诈、殴打,他们本应理直气壮地用法律手段保护自己的合法权益,伸张正义,可是,他们都不懂得法律知识,或忍气吞声,或采取极端措施报复,有时糊里糊涂走上犯罪道路。

    Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything.
