    三、科學育人抓質(zhì)量不是只抓課本知識,而是要從抓習慣、抓細節(jié)、抓學困生、抓讀書等方面入手。抓質(zhì)量要從培養(yǎng)學生良好的學習習慣入手,良好習慣的培養(yǎng),只靠班主任一人是心有余而力不足的,需要每一位教師齊心協(xié)力,齊抓共管。抓質(zhì)量要注重細節(jié),如語文要從生字、背誦開始夯實基礎,數(shù)學要從基本計算、每一個小知識點、讀題審題點滴落實。抓好每個細節(jié),進而形成習慣,學生的成績自然就會提高。抓質(zhì)量要把目光投向?qū)W困生,如課堂上設計一些學困生能夠回答上來的問題并及時表揚他們,不斷增強自信,課后適當開“小灶”,加強指導,還要跟蹤輔導,持續(xù)關注,增強他們的學習主動性和積極性,成績也會有提高。抓質(zhì)量還要抓讀書,要培養(yǎng)學生的讀書興趣,讓讀書成為學生的生活方式,不僅課上讀,還要在課外讀,不僅讓學生讀,教師自己更要讀。

    (三)鞏固內(nèi)化俗話說的好:“熟能生巧”。數(shù)學離不開練習,要掌握知識,形成技能技巧,一定要通過練習。養(yǎng)成良好的思維品質(zhì)也要通過一定的思考練習,課程標準提倡練習的有效性。對此,我非常注意將數(shù)學的思考融入不同層次的練習之中,很好的發(fā)揮練習作用。提高了教學的有效性。所以在學習完新知后我設計了兩組游泳與跑步的場景,意在讓學生知道這兩組成績排名與上面不一樣,是秒數(shù)越少成績越高.(從小到大排列)使學生明確要根據(jù)生活實際靈活的解決問題。游泳結(jié)果是9.88<10.3<11.2跑步結(jié)果是12<13.16<17.5<18.2(四)拓展練習用0、2、4、6四個數(shù)字和小數(shù)點寫出下面小數(shù),看誰寫得多。大于2的三位小數(shù)。小于6的三位小數(shù)。通過這組的練習,使學生不但鞏固了知識,更重要的是數(shù)學思維得到不斷的拓展。(五)總結(jié)歸納說一說小數(shù)比較大小的方法。并強調(diào)小數(shù)的數(shù)位多不一定大。
