除教材中的口算題目外,教師應(yīng)該再精心編制一定數(shù)量的涉及多種口算方法的練習題,在自習課上讓學生反復(fù)練習,我們要把口算訓練穿插于整個數(shù)學教學的全過程之中,使口算訓練經(jīng)?;㈤L期化,逐步提高學生數(shù)學計算的快捷性。二、注意培養(yǎng)學生估算能力 新課程把培養(yǎng)學生的估算能力列入其中,充分反映出估算在數(shù)學計算和實際生活中的重要性,估算能力也是一個人計算能力中相當重要的一個方面,具備良好的估算能力,實踐證明有四個好處:幫助我們預(yù)知計算結(jié)果;可以提高數(shù)學分析能力;可以解決實際生活問題;檢查結(jié)果是否基本正確。第五篇:提高小學生的數(shù)學計算能力提高小學生的數(shù)學計算能力一個人的數(shù)學計算能力主要包含三個方面:即計算結(jié)果的準確性,計算方法的技巧性和計算速度的快捷性,要想提高小學生數(shù)學計算能力,我認為要從下面四個方面下功夫:一、讓學生熟練掌握運算法規(guī):在小學階段,學生要學到三類數(shù)——整數(shù)(自然數(shù))、小數(shù)和分數(shù),這三類數(shù)都要進行四則運算——加、減、乘、除,每一類數(shù)的每一種運算都有自己特定的運算法則,熟練掌握各類運算法則是全面提高小學生數(shù)學計算能力的立足點和出發(fā)點。課堂采取小醫(yī)生找病因比賽的形式,讓學生在比賽中獲取知識。教師要因人、因題地重點分析錯題原因,大部分學生都做錯了的題,教師就要集中進行了講解,分析錯誤的原因;對基礎(chǔ)較差、常做錯題的學生,教師要多花時間在課后進行輔導。學生的學習是一個反復(fù)認識和實踐的過程,出錯總是難免的。仔細驗算。還要審運算順序,明確先算什么,后算什么,能簡便就簡便,做題前要做到心中有數(shù)。要求學生認真按格式書寫阿拉伯數(shù)字和運算符號,字跡要端正,這樣能有效地避免“看錯”毛病的發(fā)生。三、克服粗心,培養(yǎng)良好的計算習慣。每天利用5分鐘加強學生的口算訓練,單項的計算要根據(jù)學生掌握的情況重點練,對于學生難掌握之點易錯之處要突出練。(1)讓學生充分地“說”,把操作和語言結(jié)合起來。(3)家、校結(jié)合的教育才真正是走向了成功教育。(1)課堂上注重口算訓練。怎樣提高學生的計算能力呢?我認為應(yīng)主要從下面幾個方面入手。計算教學中,可以根據(jù)每天的教學內(nèi)容適時適量地進行一些口算訓練和筆算訓練。在計算教學中,要讓學生認識到計算能力的重要性,熟練掌握基礎(chǔ)知識,理清算法,加強訓練,培養(yǎng)學生的思維,養(yǎng)成良好的計算習慣,持之以恒,才能有效地提高小學生的計算能力。驗算不僅能保證計算正確無誤,而且還能培養(yǎng)學生對學習一絲不茍的態(tài)度。數(shù)字間的間隔要適宜,草稿上排豎式也要條理清楚,數(shù)位對齊。養(yǎng)成認真審題的習慣在教學中,應(yīng)培養(yǎng)學生認真審題,看清題目中的每一個數(shù)據(jù)和運算符號。時間一長,學生難免會出現(xiàn)厭煩、輕視的現(xiàn)象。教師應(yīng)該每天出4-6道計算題讓學生練習。有的可能是算數(shù)上的失誤,但是大多時候還是由于算理不清楚造成的。重要的地方用紅筆標示一下。從這個意義上說,加強計算教學,有效地提高計算的正確率是小學數(shù)學教學的一個非常重要方面。例如,學生在計算1258時,就很容易忘記每一位滿幾該向前一位進幾,從而導致算錯了數(shù)。然后是學生的短時記憶比較弱。定勢是一定心理活動所形成的準備狀態(tài),這種準備狀態(tài)可以決定同類后繼活動的某種趨勢。以本人經(jīng)驗,對小學生計算容易出錯的原因分析如下:首先是學生心理方面的原因。小學數(shù)學教學大綱指出:“小學數(shù)學教學的一項重要任務(wù)是培養(yǎng)計算能力,應(yīng)該要求學生算得正確、迅速,同時還應(yīng)注意計算方法的合理性和靈活性。4, there is a fault that is every time I send the homework, students are required to immediately turn to put the wrong topic review time, and see what went wrong, and timely correction, so that further deepening the students understanding of calculate theory, algorithm, achieve the goal of improve the puting capability.第三篇:淺談如何提高小學生數(shù)學計算能力淺談如何提高小學生數(shù)學計算能力梁志勇[摘要] 計算是小學數(shù)學中一項重要的基礎(chǔ)知識,貫穿于小學數(shù)學教學的全過程。不論題目是否要求驗算,都要求學生必須做到,逐漸養(yǎng)成學生良好的驗算習慣。t rush to laid hands on him, first have to look carefully, clear which step should be calculated, which is calculated after step, where to find a find method can be applied to calculation of, do know, and then carefully calculated, it is called “knife don39。Write a “7” scrawled “1”, and cause calculation is strict with students writing format, and lead by example, being a good role 、認真審題。 math error reasons not to do, but not by heart, so I think to make students form good habits as 、規(guī)范書寫。2, daily life in the life mathematics, such as street to buy clothes, about how much money need to take, need to estimate。1, the present way of life.“New standard” pointed out: through to real life situations, make students experience, feel and understand the meaning of number and operations, to be presented to students a lot of realistic background, closely related to mathematics and the in teaching 36 x 4, I import in the following way: a top 36 yuan, how much do you need to buy 4 such blouse? This way of life for the calculation type questions, students are willing to 、日常生活數(shù)學化。In addition to classroom teaching methods, the most effective way is to let students exercise in real life, in dealing with specific 、增強學生的實踐能力數(shù)學來源于生活,又服務(wù)于生活,而計算則是解決實際生活問題的重要手段。40=10003927 present 35 material present 40 4000 = 1000聯(lián)系實際估算法。估算過程中,由于學生的生活背景、思維方式的不同,估算結(jié)果也不一定一樣,因此,允許估算結(jié)果與準確值之間有一定范圍的誤差,正負誤差均可。 ability to estimate, therefore, not only can make students39。因此,重視學生估算能力的培養(yǎng),不僅可以使學生的思維更加靈活,而且對學生的直覺思維能力的培養(yǎng)有很大的幫助。t required that every student(should)use a variety of methods to solve the same problem, but rather to encourage students to think independently and solve with suitable methods, ability can use a variety of methods, without the need of students in a algorithm diversity, also want to pay attention to the optimization method, for students to e up with every kind of right way to give affirmation, persuade students give up their backward trival, to follow the outstanding, simple method, so as to make their thinking ability constantly for middle and senior each kind of algorithm, can calculate, make its own instructions in order to prevent the “l(fā)earning, do
