  • 小学数学人教版六年级上册《圆的认识》说课稿

    二、说教法学法:学生的学习过程是一个主动建构的过程,教师要激活学生的先前经验,激发 学习热情,让学生在经历、体验和运用中真正感悟知识。在动手中引导学生认识圆,理解圆的特征,有目的、有意识地安排了让学生折一折、画一画、量一量、比一比等动手实践活动,启发学生用眼观察,动脑思考,动口参加讨论,用心去辨析同学们的答案。教学中理应发挥学生的主体作用,淡化教师的主观影响,让学生自己在实践中产生问题意识,自己探究、尝试,修正错误,总结规律,从而主动获取知识。本节课我采用了多媒体教学手段,主要运用操作、探究、讨论、发现等教学方法。学生的学法与教法相对应,让学生主动探索、主动交流、主动提问。通过多媒体的直观演示将演示、观察、操作、思维与语言表达结合在一起,使学生对圆有一个形象的感知。同时作用于学生的感官,调动学生的学习积极性,给学生充分的时间和机会让他们主动参与获取知识的过程,培养学生自主学习的意识与创新意识。

  • 人教版新目标初中英语八年级上册How do you make a banana milk shake教案2篇

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。
