62、遇到很多棘手的問(wèn)題:特別是在一所農(nóng)村小學(xué),因少數(shù)學(xué)生學(xué)習(xí)有困難,使得班級(jí)的整體教學(xué)工作不能順利進(jìn)行。著名教育家韓鳳珍說(shuō)過(guò):“難教育的孩子,都是具有強(qiáng)烈自尊心的孩子。教育者就是要千方百計(jì)的保護(hù)孩子最寶貴的東西——自尊心。”在孩子的成長(zhǎng)過(guò)程中,再?zèng)]有比自尊心更重要的了。而要保護(hù)學(xué)生的自尊心,就要教師善于通過(guò)激勵(lì)來(lái)幫助學(xué)生建立積極的心態(tài),建立對(duì)自己潛能開發(fā)的自信心,這樣外力就會(huì)變?yōu)閮?nèi)力,學(xué)生就能永遠(yuǎn)前進(jìn),取得意想不到的可喜成績(jī)。我所經(jīng)歷的一件往事便證實(shí)了這一點(diǎn)。 今年我接了4,5,6年級(jí)三個(gè)班,兩個(gè)學(xué)校的英語(yǔ)課教學(xué)工作。由于老師經(jīng)常換,造成學(xué)生英語(yǔ)成績(jī)就一直不好。造成“差生”成績(jī)特差,即使把他
63、們放到5年級(jí)學(xué)生中,成績(jī)也會(huì)排在后面。他們中有些是由外地中途轉(zhuǎn)來(lái)的,從沒(méi)學(xué)過(guò)英語(yǔ),一直跟不上來(lái),便越落越遠(yuǎn);有些則是在英語(yǔ)學(xué)習(xí)方面一直有很大困難,又懶于學(xué)習(xí),不能及時(shí)完成作業(yè)。對(duì)于他們,我除了采取一些適合他們特點(diǎn)的教學(xué)方法外,還從“心上”著手,對(duì)他們經(jīng)常鼓勵(lì),表?yè)P(yáng),給以自信,使他們的學(xué)習(xí)成績(jī)逐漸有所提高。轉(zhuǎn)眼之間,已進(jìn)入期末復(fù)習(xí)階段。一天下課時(shí),我邊收拾東西邊笑著問(wèn)一個(gè)學(xué)生:期中考試你打算考多少分呀?她很自信地回答到:“我想考70分以上!”因?yàn)樗A(chǔ)太差,又經(jīng)常不完成作業(yè),以前也從未考過(guò)及格成績(jī)。而且語(yǔ)文、數(shù)學(xué)成績(jī)也不看好。所以看見她有這種想法.便很高興地點(diǎn)了點(diǎn)頭。剛要說(shuō)話,只聽語(yǔ)文老師笑著插
64、嘴到:你聽她的,他還能考上70多分?能及格就不錯(cuò)了!數(shù)學(xué)老師此時(shí)剛好也走進(jìn)教室。聽了這話,便不假思索的搶白道:“真是的、數(shù)學(xué)都不及格,英語(yǔ)還能及格?”話音沒(méi)落,就見這個(gè)學(xué)生的臉唰的紅到了脖子,羞愧的深深地埋下了頭……一剎那,我的心靈受到了強(qiáng)烈的震撼,學(xué)生那交織著自卑與痛楚的窘迫樣兒,至今還一直在我眼前浮現(xiàn)。我趕緊微笑著走到他身邊,伸出手跟他做出拉勾狀,說(shuō)到:“XX,語(yǔ)文、數(shù)學(xué)老師都不相信你能考上70多分,但我相信你能!爭(zhēng)口氣,要點(diǎn)兒強(qiáng),使使勁兒,期中考個(gè)好成績(jī)來(lái)證明給大家看,好嗎?”她他迅速伸出手,邊跟我拉勾,邊狠狠地點(diǎn)著頭:“好!我一定能考及格!” 晚上,我回到家,翻開書,陶行知老先生
65、的一首詩(shī)映入我的眼簾:“你這糊涂先生!你的教鞭下有瓦特,你的冷眼里有牛頓,你的譏笑中有愛(ài)迪生。你別急忙把他們趕跑。你可要等到坐火輪,點(diǎn)電燈,學(xué)微積分,才認(rèn)他們是你當(dāng)年的小學(xué)生?”我工工整整地把它抄在日記本上。我將時(shí)時(shí)刻刻把它銘記在心中-----為了我那些可愛(ài)的學(xué)生們…… 點(diǎn)評(píng): 現(xiàn)代教育是以學(xué)生為主體教育,而主體教育則是以人為本的教育,是要在人的內(nèi)心和行為兩方面同時(shí)造就一個(gè)獨(dú)立自主、有熱情、有個(gè)性、有尊嚴(yán),有責(zé)任心的人。經(jīng)過(guò)觀察與分析,我逐漸找出了學(xué)困生學(xué)習(xí)困難的緣由。雖然他們大部分都很聰明,但他們的學(xué)習(xí)成績(jī)與他們的智力水平反差很大,這說(shuō)明他們?cè)趯W(xué)習(xí)方面的確存在障礙,而造成這種障礙
66、的主要原因有以下兩個(gè)方面: 1.家庭教育存在問(wèn)題 這些學(xué)困生都是家中的獨(dú)生子,因從小受父母溺愛(ài),養(yǎng)成了心血來(lái)潮時(shí)就學(xué)習(xí)的、心情不好時(shí)就不學(xué)的毛?。欢麄兊募议L(zhǎng)沒(méi)有意識(shí)到及時(shí)矯正這種習(xí)慣的必要性?,F(xiàn)在他們長(zhǎng)大了,其父母?jìng)儾虐雅囵B(yǎng)他們認(rèn)真學(xué)習(xí)的習(xí)慣提到日程;但改變一個(gè)人的習(xí)慣絕非易事,他們既嫌麻煩,又沒(méi)有恒心,于是把轉(zhuǎn)變他們孩子的希望都寄托于學(xué)校和教師。 2.過(guò)分緊張,學(xué)習(xí)效果不佳 這些學(xué)困生成績(jī)不如其他同學(xué),在同學(xué)面前總有一種自愧不如的感覺(jué);但他們也想學(xué)習(xí)上與同學(xué)一起進(jìn)步,這種矛盾心理使他們產(chǎn)生了自卑感。同時(shí)他們還擔(dān)心自己學(xué)習(xí)不好會(huì)受到老師的批評(píng)和父母的責(zé)罵,過(guò)度的焦慮又使他們學(xué)習(xí)時(shí)注意力不集中,學(xué)習(xí)效果不佳。 另外六年級(jí)學(xué)生,學(xué)習(xí)英語(yǔ)已經(jīng)有三年了。面對(duì)每次考試的失敗,許多差生已經(jīng)對(duì)英語(yǔ)失去了信心,產(chǎn)生了“破罐子破摔”的想法。我便主動(dòng)接近他們,用積極的態(tài)度、真誠(chéng)
