人教版新课标小学数学五年级下册因数与倍数教案
因此，本套教材中删去了“整除”的数学化定义，而是借助整除的模式na＝b直接引出因数和倍数的概念。在本册教材中，由于允许学生采用多样的方法求最大公因数和最小公倍数，分解质因数也失去了其不可或缺的作用，同时，也是为了减少这一单元的理论概念，教材不再把它作为正式教学内容，而是作为一个补充知识，安排在“你知道吗？”中进行介绍。由于这部分内容较为抽象，很难结合生活实例或具体情境来进行教学，学生理解起来有一定的难度。在过去的教学中，一些教师往往忽视概念的本质，而是让学生死记硬背相关概念或结论，学生无法理清各概念间的前后承接关系，达不到融会贯通的程度。再加上有些教师在考核时使用一些偏题、难题，导致学生在学习这部分知识时觉得枯燥乏味，体会不到初等数论的抽象性、严密性和逻辑性，感受不到数学的魅力。所以在教学中应注意以下两点: （1）加强对概念间相互关系的梳理，引导学生从本质上理解概念，避免死记硬背。（2）由于本单元知识特有的抽象性，教学时要注意培养学生的抽象思维能力。

精编个人工匠精神学习心得体会与感受优选八篇
“创意无限，匠心支撑”。当下，创新创业大潮涌动，“互联网+”颇受青睐，大批创客投身其中。这里头有脚踏实地的深耕者，但也有不少一天到晚想着如何造噱头、拉投资，幻想借互联网的东风，“抄一把就走”之人。与此相应，很多产品往往火了一把便再无踪迹。如此“创”法，除了搅出些过时即破的泡沫，难言价值。创新创业不应成为浮躁的代名词，那些真正成功的互联网神话缔造者，远非鼓吹概念、贩卖情怀这么简单。很多大佬正是以其对细节近乎严苛的追求向大家证明，只有“互联网+工匠精神”，才能出优质产品。
精编个人学习红军长征精神心得体会与感受八篇
二万五千里长征，一次改变中国人命运的征程已在人们的评说中去过了大半个世纪。照现代社会这种急速更新换代的观念，早已是好几个时代过去了。按我们熟悉的某种号召“过去的就让它过去吧”。再说下去，就成了枭鸣似的烦扰，不免令人生厌。然而长征却不同。人们总在不断的言说、探究、拷问。我想或许是由于长征所代表的一种精神吧――一种全人类永恒追求的精神――坚持到底。 “红军不怕远征难”的精神！正因为这心中永存的信念，红军才有了“万水千山只等闲，五岭逶迤腾细浪，乌蒙磅礴走泥丸”的英雄气概！正因为这心中永存的信念，才有了“亲人送水来解渴，军民鱼水一家人”的温情！
