北师大初中七年级数学上册代数式教案2

  • 关于大学生三下乡支教教育个人心得体会八篇

    我也是农村长大的孩子,在农村的日子就是我整个童年,虽然没有城市的繁荣和物质基础,但在农村我就是一只自由自在、欢乐无比的小鸟。走进白石小学,我仿佛又回到了我那个自由洒脱的童年。孩子们的欢声笑语,孩子们的调皮捣蛋,还有孩子们的聪明伶俐,无不让我感到开心和幸福。这种幸福感不像是亲人朋友给予的爱,而是把你带进你无法回到的过去的难忘时光。在我们安排的课程中,里面大多数是以第二课堂为主。为了吸引孩子们的注意和培养他们的兴趣,我们也是使出浑身解数,让课程变得有趣而不乏味。虽然经历了当老师的辛苦,但孩子们带给我们的欢乐和感动让我们觉得一切都值得。在我所参与的课堂中,我看到了“老师们”的窘迫,但孩子们却还是学得很认真笑得很开心。这就是我们现在无法相比的,孩子们的天真热情,单纯可爱,让我们这些最初不抱好想法的大学生感到温暖,很快,我们就融入其中了。

  • 关于大学生三下乡支教教育个人心得体会八篇

    在我们教授孩子们知识的同时,也受到孩子们很多的启发。比如说,在课堂上我按照自己的备课套路跟孩子们讲课,孩子们有的时候并没有听进去。确切地说是没有听懂。作为一位准教师,我没有按照实际情况去衡量,不仅没有预想的效果,反而造成孩子厌学的情绪。经过多次授课,我们在孩子们身上反馈的信息比我们教给孩子们的还要丰富。所以有时我都觉得,其实三下乡最大的作用是教会我们这些大学生如何成长为一个合格的老师的。还有在孩子们身上学到的乐观、坚强,都是我遗失了很久的宝贝。

  • 小班科学教案 奇妙的颜色王国

    【幼儿分析】 小班的小朋友年龄普遍偏小,再加上家长对方面的教育相对薄弱点,刚入园时只有几个幼儿能认识几种主色调,大部分的幼儿一种颜色也不认识。因此如何教会幼儿认识颜色是我们老师迫切需要解决的问题。为了让幼儿迅速掌握颜色,我根据幼儿的年龄特点,在本次活动中,为幼儿创设了相关课题情景的内容,让孩子们在兴高采烈地活动、游戏中不知不觉的掌握抽象的颜色。 【活动目标】 1、培养对颜色的兴趣,认识红、黄、蓝三原色。 2、初步培养幼儿的观察能力,动手操作的能力。 3、初步在探索中懂得将两种颜色混在一起可以变成另外的一种颜色,产生探索周围事物颜色的兴趣。 【活动准备】 1、红、黄、蓝颜料、棉签若干、颜料盒若干。 2、透明玻璃板若干。 3、颜色小精灵的图片一张。 4、绘画纸人手一份。

  • 学校远程教育年度工作计划3篇

  • 大班语言《举世无双的建筑师》说课稿

    2、活动目标:1)了解鸟的不同筑巢方法,激发幼儿探索鸟的兴趣。2)培养幼儿对鸟类的爱护及大自然的热爱之情。这样两条目标符合大班幼儿的年龄特点,又符合二期课改的理念,既有认知要求,又有情感激发。3、重点:了解鸟的不同筑巢方法。4、难点:理解鸟使用的不同材料与鸟各自生活习性,特征的关系。由于这两个方面对幼儿生活经验比较远,鸟的筑巢方法和鸟的生活习性,特点有很大关系,但很隐蔽不容易发现。所以作为难点。二、说教法、说学法1、说教法:1)创设情景法:大班幼儿情感的稳定性和有意性逐渐增长。教师创设一定的情景画面,(鸟的叫声、关在笼子里的鸟、树林里准备筑巢的鸟的画面)激发幼儿幼儿对动物,鸟类的同情,从而产生对鸟类的关注,对鸟类的生活环境的思考。并为后面小鸟筑巢做好铺垫。引起幼儿对后面活动的兴趣。2)动手操作法:大班幼儿随着年龄的增长,他们的思维已由直觉行动思维过渡到具体形象思维。他们喜欢听故事,喜欢动手操作。教师准备树枝、柳絮、有小树洞的树根、泥浆土。以及记录卡和笔。让孩子在了解这几种鸟的特点后通过摸摸、比比、做做等方法探索鸟的不同筑巢方法,并做记录。充分调动起幼儿学习的主动性和积极性。3)符号记录法:大班幼儿表现表达的欲望与能力逐渐增强,教师要抓住时机利用任何机会引导幼儿用多种方法表达。符号记录也是幼儿的一种表达方法。教师让幼儿自己操作后记录。提高幼儿记录的能力。4)交流讨论法:操作以后的交流讨论,是幼儿对自己探索后的另外一种表达形式。在幼儿的交流讨论中教师通过观察、聆听了解幼儿的思维方法,经验积累的程度,适时适度地帮幼儿归纳、总结、提升。并推动活动朝更深层次发展。5)阅读法:大班幼儿的年龄特点中指出:幼儿阅读兴趣明显提高,能较长时间地看书,对内容的理解能力较强。而且开始对文字感性趣。因此,请幼儿边翻阅图书边听老师讲故事,不但帮助幼儿养成良好的阅读方法和习惯,并从阅读的故事中寻找,验证自己的答案。这也是养成良好学习方法的一个方面。

  • 幼儿园中班教案说课稿 搬新家

    在“我爱我家”主题开展过程中,我们为幼儿创设了一种家的氛围,让幼儿产生爱的体验。我想,音乐活动也可以配合这一主题,丰富幼儿的情感。因此,我就想以大头儿子和小头爸爸这两个幼儿耳熟能详的动画人物为主人公,创设一个活动情景作为本次活动的载体。一方面,活动中的律动动作大部分是双人动作,如亲一亲、抱一抱、压跷跷板等,既能在日常生活中幼儿与父母身上找到痕迹,又能体现亲子感情,所以用大头儿子和小头爸爸贯穿整个活动,可以自然地激发幼儿对家人、对亲情的认知和体验。
