  • 人教部编版道德与法制一年级下册我不拖拉说课稿

    人教部编版道德与法制一年级下册我不拖拉说课稿

    为让学生深刻认识到做事拖拉的后果严重,在本活动环节中,我借用了小学语文课本中的《一分钟》故事,同时让孩子们对故事中主人公“元元”的未来生活进行设想。孩子们在故事倾听和畅想中,深深感受到做事拖拉,后果严重。同时,两个“一分钟游戏”让孩子们体会到时间宝贵,不能随便浪费,从而树立做事不拖拉的意识。活动四:续故事,告别“拖拉”此活动是对“第一板块的活动”的呼应,再次呈现“拖拉鸟”,请学生说说现在有什么话想对它说。接着,是“拖拉鸟”的自我反省:“小朋友们,听了大家的话,我觉得拖拖拉拉真是个不好的习惯,我要马上改掉这个坏习惯。再见啦!趁着天气好,我要赶紧搭窝去!再见!”最后,让学生展开想象,给改掉坏习惯后的“拖拉鸟”,重新取个名字。该环节的设计非常富有童趣。孩子都向往美好的事物,所以本环节的续编故事用意就在于让孩子懂得知错就改,为时不晚。引导他们愿意努力改掉之前的拖拉习惯,树立做事不拖拉的意识。这也是为第二课时的学习做了铺垫。

    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.
