國旗下的講話：做一個(gè)有道德的人
國旗下的講話：做一個(gè)有道德的人老師們、同學(xué)們：大家上午好！今天我講的題目是《做一個(gè)有道德的人》。意大利詩人但丁曾說過：“一個(gè)知識(shí)不健全的人，可以用道德來彌補(bǔ)，而一個(gè)道德不健全的人，卻難以用知識(shí)來彌補(bǔ)。”上下五千年以來，道德一直是我們?nèi)A夏兒女的寶藏。道德，是一種美德，是一種財(cái)富，更是一種智慧。道德源自于我們的內(nèi)心，有了道德感，自己做出的事情自然就不會(huì)錯(cuò)。做好事，不是為了得到誰的表揚(yáng)，得到怎樣的榮譽(yù)。真正的道德，發(fā)自內(nèi)心，你對(duì)社會(huì)，對(duì)每個(gè)人的愛，就是一份珍貴的道德。文明很小很小，但是只要每一個(gè)人都做文明的好事，就能使社會(huì)文明邁出一大步。一件小事很小很小，但是用處卻很大很大。每一份文明就是一份力量，無數(shù)文明在一起就會(huì)產(chǎn)生一種無與倫比的力量，這種力量如破土的小苗，在每一個(gè)人的心里萌發(fā)。
關(guān)于做有道德的人的國旗下的講話
我們要做有道德的人“道德”一詞由來已久，早在兩千多年以前，我國古代的著作中就出現(xiàn)了“道德”這個(gè)詞語，“德”指內(nèi)心的情感或者信念，用于人倫；“道”則指人的本性，品德，儒家認(rèn)為，“德”包括忠、孝、仁、義、溫良、恭敬、謙讓等，道家則以為所謂天地萬物這自然為“道”，而各種事物所得之自然為“德”，對(duì)人而言，便是品德，從中國儒家的創(chuàng)始人，偉大的思想家，教育家孔子開始，千百年來人們就一直重視道德問題。在現(xiàn)實(shí)生活中，經(jīng)常有類似損人不利己的事情發(fā)生，比如上車，購物不排隊(duì)，大家擠得難受；比如地鐵列車和電梯開時(shí)堵在門兩邊，擠得里面的人出不來；又比如不守交通規(guī)則，造成交通堵塞或車禍，損人利己這方面例子太多了，大到盜竊、詐騙、謀財(cái)害命，小到逃票、偷撕別人郵票，在借的書上（特別是公共圖書館里借的書）亂畫，偷撕公共圖書雜志，在圖書管聊天，在公共場合抽煙等。

1，猜一猜 師：這里有一個(gè)盒子，盒子里有一朵花，誰能猜出這朵花是什么顏色的？盒子里的花兒的顏色是確定的，為什么你們會(huì)有那么多不同的答案？ ……師：好，老師給一個(gè)提示：紅色和黃色。會(huì)是什么顏色呢？師：要想準(zhǔn)確猜出球的顏色，有一個(gè)統(tǒng)一的答案，怎么辦？ 師：滿足你的愿望，第二個(gè)提示：不是紅色的。2、猜球游戲： 小朋友看，老師這里有一個(gè)白色和一個(gè)黃色的乒乓球，現(xiàn)在把它們放到盒子里，我們一起來玩一個(gè)猜一猜的游戲，好嗎？ 師：我摸出其中一個(gè)，你猜猜是什么顏色的球呢？師：猜得準(zhǔn)嗎？老師給你們一些提示吧：我摸出的不是黃球，那我摸出的是什么顏色的球？你是怎么猜的？師：那盒子里面的是什么顏色的球呢？你是怎么猜的？小朋友們很聰明，根據(jù)老師的提示能準(zhǔn)確地判斷出球的顏色，這種方法就是我們今天要學(xué)習(xí)的簡單的推理。

問題情景，導(dǎo)入新課１、多媒體課件出示例１主題圖，問：圖上的小朋友在干什么？你們測量過體重嗎？測量了幾次？讀一年級(jí)剛?cè)雽W(xué)時(shí)，你測量的體重是多少？（學(xué)生自由匯報(bào)各自的體重情況）怎樣才能讓大家一看就明白我們班所有人的體重情況呢？二、活動(dòng)體驗(yàn)，探究新知１、電腦出示統(tǒng)計(jì)表（１）： 體重（千克）１５以下１６～２０ ２１～２５ ２６～３０ ３１以上人數(shù) 師：現(xiàn)在我們就用“正”字記錄法來統(tǒng)計(jì)一下剛?cè)雽W(xué)時(shí)的體重（集體活動(dòng)）２、活動(dòng)結(jié)束后，師生共同將收集的數(shù)據(jù)整理后填入表格中。３、二年級(jí)時(shí)，我們的體重有什么變化呢？ 電腦出示統(tǒng)計(jì)表（２） 體重（千克）１５以下１６～２０ ２１～２５ ２６～３０ ３１以上人數(shù) 集體進(jìn)行統(tǒng)計(jì)活動(dòng)，并將結(jié)果填入表中。４、討論：如果想把兩年的體重?cái)?shù)據(jù)填入一個(gè)統(tǒng)計(jì)表中，該如何表示呢？ 學(xué)生討論后，在黑板上出示表格（３）：（單位：千克）
