万里一线牵 说课稿
尊敬的各位评委、各位老师，大家好，今天我说课的内容是《万里一线牵》。下面我将从“说教材”、“说学情”、“说教法”、“说程序”、“说板书”五个方面对本课进行具体研说,恳请大家批评指正。一、依标扣本，说教材《万里一线牵》是部编版《道德与法治》三年级下册第四单元《多样的交通和通信》的第三个主题中的内容。这个主题主要是了解多样便捷的现代通信方式；通过古今通信方式的对比，感受通信发展给人们带来的便利。本课教学通过帮助学生运用已有的生活经验和调查资料相对比，通过对知识的探究发现问题，从而使学生对现代通信方式的发展有初步了解，知道多种多样的现代通信方式，以及通信方式的发展给人们生活带来的便利。 二、以人为本，说学情对于现代通信方式,小学生使用的已经很广泛了,但是小学生真正运用现代通信方式解决生活问题的经验不足、缺乏体验,对本知识点的了解很少。因此,依据学生的生活实际和本课的教学目标,我以学生的生活实际为起点,利用课程资源,使教学与学生生活贴得更近,让学生更好的感受现代通信的迅猛发展,以及给生活带来的无限便捷,体验通信愉悦,并在以后的生活中学会合理运用通信方式解决实际问题,更好地服务于当下和未来的生活。

新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

思考：洗衣机脱水时转速高时容易甩干衣物，还是转速低时容易甩干衣物？(2) 制作棉花糖的原理内筒与洗衣机的脱水筒相似，里面加入白砂糖，加热使糖熔化成糖汁。内筒高速旋转，黏稠的糖汁就做离心运动，从内筒壁的小孔飞散出去，成为丝状到达温度较低的外筒，并迅速冷却凝固，变得纤细雪白，像一团团棉花。5.离心现象的防止在水平公路上行驶的汽车，转弯时所需的向心力是由车轮与路面的静摩擦力提供的。如果转弯时速度过大，所需向心力F大于最大静摩擦力Fmax，汽车将做离心运动而造成交通事故。因此，在公路弯道处，车辆行驶不允许超过规定的速度。当高速转动的砂轮或者飞轮内部分子间相互作用力不足以提供所需向心力时，离心运动就会使他们破裂，甚至酿成事故。

精编开展家庭教育学习心得感悟参考范文
现在，他们就语文、数学和英语三门主课，不能因为孩子爱学语文就放松数学和英语，或是爱好数学、英语而放松语文。作为家长，我们也是从学生时代走过来的，如果从小对学科有了好恶，那往后的学习就会出现偏差，单科成绩不好不说，更重要的是会影响孩子的健康成长。像赵艺樯，刚开始对学习英语很没兴趣，还说中国人为什么要学外国话。针对她的这种情况，我从她想当科学家引导她：我们国家现在的科学家，你看有谁不懂外语呢?你现在不学好英语，以后怎么看外国的科研资料，怎么或者和国外的科学家交流?英语可是当今世界好多国家通用的语言。通过这样的对话，使她懂得了学习英语的重要性，慢慢地她对英语也不再排斥，成绩也有所提高。
