面入手。整理課題研究的過(guò)程性材料,進(jìn)行分析、歸納、提煉、總結(jié),撰寫(xiě)研究報(bào)告,實(shí)驗(yàn)教師撰寫(xiě)研究論文,全面展示研究成果,準(zhǔn)備驗(yàn)收。實(shí)施階段:(2014年5月——2015年6月)實(shí)施研究方案。通過(guò)平時(shí)觀察和問(wèn)卷調(diào)查相結(jié)合的方式,了解學(xué)生在計(jì)算課堂中態(tài)度與思維方面的實(shí)際情況,了解學(xué)生計(jì)算正確率的狀況,分析原因,研究策略。五、研究的內(nèi)容和目的研究的內(nèi)容:分析造成學(xué)生數(shù)學(xué)計(jì)算的速度慢和計(jì)算正確率低的原因。系統(tǒng)觀察小學(xué)數(shù)學(xué)教學(xué),計(jì)算教學(xué)占有非常大的比重,單看每?jī)?cè)的教材目錄就能發(fā)現(xiàn);并且在學(xué)生練習(xí)冊(cè)中,計(jì)算的比重也是顯而易見(jiàn)的,單是一張數(shù)學(xué)試卷,從簡(jiǎn)單的分值來(lái)看,100分的試卷中計(jì)算就占了40分,還不包括填空、判斷、選擇、解決問(wèn)題、綜合運(yùn)用中的計(jì)算。經(jīng)領(lǐng)導(dǎo)批準(zhǔn),今天開(kāi)題,我代表課題組,將本課題的有關(guān)情況向各位領(lǐng)導(dǎo)、專家和老師們匯報(bào)如下:一、本課題選題依據(jù)理論依據(jù):《數(shù)學(xué)課標(biāo)》中規(guī)定:“要使學(xué)生具有進(jìn)行整數(shù)、小數(shù)、分?jǐn)?shù)的四則運(yùn)算的能力。教師必須以身作則,作學(xué)生的表率。(六)培養(yǎng)學(xué)生良好的計(jì)算習(xí)慣良好的計(jì)算習(xí)慣,直接影響學(xué)生計(jì)算能力的形成和提高。(四)循序漸進(jìn)的進(jìn)行加強(qiáng)訓(xùn)練。(二)要重視學(xué)生的初次感知。短時(shí)記憶一般是保存信息的時(shí)間在1分鐘左右,這1分鐘的保存時(shí)間雖然很短,但是在計(jì)算的過(guò)程中還是十分重要的?!贝蠖鄶?shù)學(xué)生對(duì)計(jì)算題都十分輕視,在他們看來(lái),計(jì)算只不過(guò)是算數(shù),是最不用動(dòng)腦筋的數(shù)學(xué)題。所以培養(yǎng)小學(xué)生的計(jì)算能力,就尤為重要。t give students changed to topic calculation work by 、勤于驗(yàn)算。教師要嚴(yán)格要求學(xué)生的書(shū)寫(xiě)格式,并以身作則,當(dāng)好榜樣。在隨家長(zhǎng)買(mǎi)菜時(shí),要特別留心售貨員是如何快速算出結(jié)果的。2, contact the actual as puting, rent a car number, floor number to buy brick, etc., must be an integer, and must adopt “into a”。 ability of intuition thinking has a lot of the same time, strengthen the estimation, can deepen students understanding of digital, promote the cultivation of number sense, enhance the consciousness of applied mathematics, improve the ability of solving practical the teaching, I regularly throughout some estimation techniques and methods:近似估算法。 logical thinking and the role of oral expression 、重視估算,教給方法Third, the value estimate, teach method在日常生活和生產(chǎn)實(shí)際中,某些計(jì)算和測(cè)量的結(jié)果無(wú)法得到或沒(méi)有必要得到精確計(jì)算結(jié)果或判斷時(shí),就要用到估算的方法。To make the student union, must make it clear to calculate, this requires teachers to the algorithm and the principle of teaching must be correct, because the first impression is very important, for the first time speak wrong, it is hard to remove it a psychologist said: first perception of new knowledge, proactive inhibition of information into the brain can be affected by the interference, can leave deep impression in students39。With a number is multiplied by 5, 25, 125, can use opportunely calculate method:245=24247。我的具體做法是:Oral is the basis of manual putation and estimation, Jane is, in any integer, decimal1addition and subtraction, or, method, and the four mixed operation, cannot leave the as: 360 present 18 = 360 present nine members present 2 = 40 members present 2 = 20, in the process of the abridged, using three oral such as calculation of 5764 + 3821, and, need four addition oral, any a link error, can lead to , to improve the elementary

課題研究的步驟:申報(bào)階段(2015年3月)根據(jù)本校教育教學(xué)情況選題,申報(bào)課題。收集材料,掌握理論,研究現(xiàn)象。第一篇:如何提高小學(xué)生數(shù)學(xué)計(jì)算能力》開(kāi)題報(bào)告如何提高小學(xué)生數(shù)學(xué)計(jì)算能力專題研究開(kāi)題報(bào)告(2014—2015學(xué)年度 第二學(xué)期)中衛(wèi)九小 三、四年級(jí)數(shù)學(xué)組課題名稱:如何提高小學(xué)生數(shù)學(xué)計(jì)算能力 課題組成員 負(fù)責(zé)人:官小華組 員:馬霞 李秀紅 白慧云所在單位:中衛(wèi)市第九小學(xué)(三、四年級(jí)數(shù)學(xué)組)一、課題研究的背景和意義根據(jù)平時(shí)作業(yè)以及單元測(cè)試和期末測(cè)試的質(zhì)量分析情況看,發(fā)現(xiàn)我校學(xué)生在計(jì)算方面普遍存在速度慢、方法不靈活等因素,從而造成學(xué)習(xí)質(zhì)量有較大的差距。四、課題研究方法:文獻(xiàn)研究法。實(shí)驗(yàn)教師圍繞研究課題,結(jié)合研究實(shí)踐,積極進(jìn)行經(jīng)驗(yàn)總結(jié),及時(shí)將教學(xué)實(shí)踐上升為經(jīng)驗(yàn)理論,并初步形成具有一定實(shí)用價(jià)值的經(jīng)驗(yàn)體系。既要關(guān)注能力相對(duì)好的學(xué)生更要關(guān)心能力相對(duì)低的學(xué)生,讓他們體驗(yàn)到成功的喜悅,從而對(duì)自己充滿信心?!度绾翁岣咝W(xué)生數(shù)學(xué)計(jì)算能力專題研究》結(jié)題報(bào)告。我覺(jué)得計(jì)算能力是每個(gè)人必備的一項(xiàng)基本功,培養(yǎng)學(xué)生的計(jì)算能力也是小學(xué)生數(shù)學(xué)教學(xué)中的一項(xiàng)重要任務(wù),是學(xué)生學(xué)好數(shù)學(xué)的重要基礎(chǔ)。Number sense, it with the music of the “music” and “beauty” of art, maths has “number sense”.In the teaching, lets the student to observe, from the view of mathematics understanding things around, using mathematical concepts and language to reflect and describe the problem of social production and life, bined with the concrete facts of life to teaching mathematics knowledge, let students experience mathematics on the side, everywhere in the life mathematics, with positive attitude in learning, experience the “number sense”.強(qiáng)化口算。因此,要提高小學(xué)生的計(jì)算能力,就必須從強(qiáng)化口算能力抓起,把口算訓(xùn)練當(dāng)作一項(xiàng)常規(guī)工作來(lái)抓。如:一個(gè)數(shù)與“11”相乘,“兩邊一拉,中間一加,滿十向前一位進(jìn)一”;一個(gè)數(shù)與2125相乘,都可以運(yùn)用巧算方法:(2)memory and some monly used data coincidence counting addition and subtraction, multiplication table within 20, 120 square number, etc., require students to memorize and to the point of blurt the same time, often teach students some clever calculate way, also can make its calculation speed is greatly as: is multiplied by a number from “11”, “on both sides of a pull, a middle, ten a into a” forward。因此,教師必須充分備課,選擇最優(yōu)方案,以期達(dá)到良好的教學(xué)效果。t know why”, at the sam
