12、有目的、有方案的先安排與幼兒生活接近的，能理解的觀察內(nèi)容。隨機觀察也是不可少的，是相當有趣的，如蜻蜓、蚯蚓、毛毛蟲等，孩子一邊觀察，一邊提問，興趣很濃。我提供的觀察對象，注意形象逼真，色彩鮮明，大小適中，引導幼兒多角度多層面地進展觀察，保證每個幼兒看得到，看得清?？吹们宀拍苷f得正確。在觀察過程中指導。我注意幫助幼兒學習正確的觀察方法，即按順序觀察和抓住事物的不同特征重點觀察，觀察與說話相結(jié)合，在觀察中積累詞匯，理解詞匯，如一次我抓住時機，引導幼兒觀察雷雨，雷雨前天空急劇變化，烏云密布，我問幼兒烏云是什么樣子的，有的孩子說：烏云像大海的波浪。有的孩子說“烏云跑得飛快。我加以肯定說“這是烏云滾滾。

19、幾千個漢字,熟記幾百篇文章,寫出的詩文也是字斟句酌,瑯瑯上口,成為滿腹經(jīng)綸的文人。為什么在現(xiàn)代化教學的今天,我們念了十幾年書的高中畢業(yè)生甚至大學生,竟提起作文就頭疼,寫不出像樣的文章呢?呂叔湘先生早在1978年就鋒利地提出:“中小學語文教學效果差,中學語文畢業(yè)生語文程度低,十幾年上課總時數(shù)是9160課時,語文是2749課時,恰好是30%,十年的時間,二千七百多課時,用來學本國語文,卻是大多數(shù)不過關,豈非咄咄怪事!尋根究底,其主要原因就是腹中無物。特別是寫議論文,初中程度以上的學生都知道議論文的“三要素是論點、論據(jù)、論證,也通曉議論文的根本構(gòu)造:提出問題分析問題解決問題,但真正動起筆來就犯難了。

20、知道“是這樣,就是講不出“為什么。根本原因還是無“米下“鍋。于是便翻開作文集錦之類的書大段抄起來,抄人家的名言警句,抄人家的事例,不參考作文書就很難寫出像樣的文章。所以,詞匯貧乏、內(nèi)容空洞、千篇一律便成了中學生作文的通病。要解決這個問題,不能單在布局謀篇等寫作技方面下功夫,必須認識到“死記硬背的重要性,讓學生積累足夠的“米。- I believe not. He _ so careless.“教書先生恐怕是市井百姓最為熟悉的一種稱呼，從最初的門館、私塾到晚清的學堂，“教書先生那一行當怎么說也算是讓國人景仰甚或敬畏的一種社會職業(yè)。只是更早的“先生概念并非源于教書，最初出現(xiàn)的“先生一詞也并非有傳授

21、知識那般的含義。?孟子?中的“先生何為出此言也？；?論語?中的“有酒食，先生饌；?國策?中的“先生坐，何至于此？等等，均指“先生為父兄或有學問、有德行的長輩。其實?國策?中本身就有“先生長者，有德之稱的說法?？梢姟跋壬夥钦嬲摹袄蠋熤猓故桥c當今“先生的稱呼更接近?？磥?，“先生之根源含義在于禮貌和尊稱，并非具學問者的專稱。稱“老師為“先生的記載，首見于?禮記?曲禮?，有“從于先生，不越禮而與人言，其中之“先生意為“年長、資深之傳授知識者，與老師、老師之意根本一致。A. shouldnt have been B. wouldnt have been唐宋或更早之前，針對“經(jīng)學“律學“算學和“書學各科目，其相應傳授者稱為“博士，這與當今“博士含義已經(jīng)相去甚遠。而對那些特別講授“武事或講解“經(jīng)籍者，又稱“講師?！敖淌诤汀爸叹瓰閷W官稱謂。前者始于宋，乃“宗學“律學“醫(yī)學“武學等科目的講授者；而后者那么于西晉武帝時代即已設立了，主要協(xié)助國子、博士培養(yǎng)生徒?！爸淘诠糯粌H要作入流的學問，其教書育人的職責也十清楚晰。唐代國子學、太學等所設之“助教一席，也是當朝打眼的學官。至明清兩代，只設國子監(jiān)國子學一科的“助教，其身價不謂顯赫，也稱得上朝廷要員。至此，無論是“博士“講師，還是“教授“助教，其今日老師應具有的根本概念都具有了。C. co
