人教A版高中数学必修一奇偶性教学设计(2)

  • 小学数学万能说课稿

    小学数学万能说课稿

    一、 设计理念新课程标准强调的数学学习的基本理念之一人人都能获得良好的数学教育,不同的人在数学上得到不同的发展。基于以上理念,我们必须改革课堂教学中教师始终“讲”、学生被动“听”的局面,将传统意义上的“学生除了做题还是做题”的“纸笔方式”创造性地设计成学生动手操作方式。充分相信学生,把学习的主动权交给学生,充分调动学生的学习积极性。为此,我在教学设计的时候要力求做到“生活问题数学化”。始终将数学的教与学置于各种奇妙的富于思考的问题情境之中,让学生用脑想数学,用脑积极地思考数学或与之有关的问题。这种设计就是很好地贯穿了问题化设计理念。在教学中采用了“引导探索学习,促进主动发展”的教学方法,让学生真正成为学习的主人,学会学习,培养学生学数学,用数学的情感。

    2月小学国旗下讲话

    尊敬的老师、亲爱的同学们:早上好!法国学者培根说过,“习惯是人生的主宰,人们应该努力追求好习惯。”是的,行为习惯就像我们身上的指南针,指引着我们的行动。爱因斯坦有句名言,“一个人取得的成绩往往取决于性格上的伟大。”而构成性格的,正是日常生活中的一个个好习惯。好习惯养成得越多,个人的能力就越强。养成好的习惯,就如同为梦想插上了翅膀,它将为人生的成功打下坚定的基石。小时候的鲁迅先生,就养成了不迟到的习惯,他要求自己抓紧时间,时刻叮嘱自己凡事都要早做。这位以“小跑走完一生”的作家,在中国文学史上留下了辉煌的业绩。可见,行为习惯对一个人各方面的素质起了决定性的作用。在中国南方发生过这样一个故事:一家著名的企业公开招聘管理人才,在应聘者当中,有高学历的人,也有口才非常出众的公关人员,更有曾经从事过管理工作的人。但是,到了最后,负责招聘的企业老总却选中了一位在走廊上随手捡起一张废纸的应聘者。有人问企业老总:“为什么你要选那位不占任何优势的应聘的人呢?”企业老总回答说,“一个有好习惯的员工,就是一座金矿;有这种人格魅力的人,一定可以为公司创造更多的财富。”是的,当一个人养成了良好的习惯,他的人格魅力便会自然得到提升。

    大班数学《数的守恒》说课稿

    守恒包括数的守恒、长度守恒、液量守恒、物质的量(固体量)守恒、面积守恒、质量守恒、容积守恒等。大班幼儿认知活动的具体形象性和行为的有意性明显发展,能依靠表象进行思维,认知活动的概括性使幼儿对事物的理解增强,但仍显表面化、肤浅化。因此本次活动选择的内容是网络图数守恒中的一个内容6以内数的守恒,旨在让幼儿在游戏中愉快地学习数的守恒,通过自身的操作,初步感知物体位置发生变化,总数不变的数现象。让幼儿在看一看、说一说、玩一玩、摆一摆中理解数的守恒,使幼儿对数的守恒有初步的概念。数的守恒是指物体数目不因物体外部特征和排列形式等的改变而改变,物体的数目与物体的大小、颜色、形状及排列疏密没有关系(评价标准:知道比较两组物体的多少,要以物体的数目来判断)。
