    三、說教學(xué)重點、難點重點是小數(shù)乘法的豎式計算方法和積與乘數(shù)的大小關(guān)系。難點是小數(shù)乘法中乘數(shù)末位有0的計算。四、說學(xué)情在進(jìn)行本節(jié)內(nèi)容學(xué)習(xí)之前,學(xué)生已經(jīng)學(xué)習(xí)了整數(shù)乘法的運算規(guī)律,小數(shù)的意義及其加減法,還有小數(shù)乘法的計算規(guī)律。本節(jié)內(nèi)容重點是學(xué)會把小數(shù)乘法的運算方法應(yīng)用到解決實際問題中去。根據(jù)四年級學(xué)生的認(rèn)知特點和課堂注意力時間有限的特點,在教學(xué)中一定要提高課堂效率五、說教法、學(xué)法在本課教學(xué)中,我采取的教學(xué)方法是:1.通過復(fù)習(xí),回顧計算規(guī)律,并把它應(yīng)用到豎式中去。2.情境展示,把數(shù)學(xué)問題直接放在實際問題中來學(xué)習(xí)并解決。3.解決問題時采用自主探索、獨立思考和小組合作交流的學(xué)習(xí)方式。通過這些教學(xué)法激發(fā)學(xué)生學(xué)習(xí)的積極性和主動性,引導(dǎo)學(xué)生把學(xué)到的規(guī)律應(yīng)用到現(xiàn)實生活中來解決實際問題。六、說教學(xué)過程(一)舉例說明積的小數(shù)位數(shù)與乘數(shù)小數(shù)位數(shù)的關(guān)系。通過比眼力,做一做,復(fù)習(xí)前一節(jié)課所學(xué)內(nèi)容,為本節(jié)課打下基礎(chǔ)。

    Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.

    《一次函數(shù)與二元一次方程組》說課稿

    一、 說教材、目標(biāo)這部分內(nèi)容建立在學(xué)生對一元一次方程、二元一次方程組和一元一次不等式等以一次(線性)運算為基礎(chǔ)的數(shù)學(xué)模型的已有認(rèn)識上,從變化和對應(yīng)的角度對一次運算進(jìn)行更深入的討論。從函數(shù)的角度對一次方程(組)、不等式重新進(jìn)行了分析,這種再認(rèn)識不是對原有知識的簡單回顧復(fù)習(xí),而是站在更高起點上的動態(tài)分析,是用一次函數(shù)將上述三個不同的數(shù)學(xué)對象起來認(rèn)識,發(fā)揮函數(shù)對相關(guān)內(nèi)容的統(tǒng)領(lǐng)作用。通過這部分內(nèi)容的學(xué)習(xí),不僅可以加深學(xué)生對方程(組)、不等式等數(shù)學(xué)對象的理解,而且可以增強對相關(guān)知識的內(nèi)在聯(lián)系的認(rèn)識,加強知識間橫向與縱向的融會貫通,提高靈活分析和解決問題的能力。本節(jié)課是在前兩節(jié)課已經(jīng)學(xué)完了一次函數(shù)與一元一次方程、一元一次不等式的聯(lián)系之后,對一次函數(shù)與二元一次方程(組)關(guān)系的探索,是對一次函數(shù)及其相關(guān)內(nèi)容更深入、更全面的學(xué)習(xí),也是對這部分內(nèi)容的一個提升和總結(jié)。

    教材分析:本課選用兒童熟悉喜好的瓜果為內(nèi)容題材,并視之為繪畫學(xué)習(xí)的切入點。通過觀察辨識了解瓜果的形狀和特點,品嘗其色香滋味,使學(xué)生從感官的滿足引發(fā)表現(xiàn)的欲望,促進(jìn)主動地投入學(xué)習(xí)。本課教學(xué)內(nèi)容偏重于對各種瓜果的形狀和色彩運用的認(rèn)識和表現(xiàn),通過對瓜果的觀察了解,畫學(xué)生喜愛的水果,幫助他們建立親近生活的熱烈情感。所以我把認(rèn)識瓜果的基本形狀和了解熟悉色彩運用的基本知識與方法定為教學(xué)重點。由于學(xué)習(xí)內(nèi)容接近學(xué)生生活,在直接體驗的基礎(chǔ)上,學(xué)生一般能夠掌握瓜果造型的特點,并饒有興趣地投入到學(xué)習(xí)活動中去。為了更好的拓展學(xué)生的想象空間,所以,在教學(xué)中我把豐富的創(chuàng)造想象定為教學(xué)難點.

    一.關(guān)于教學(xué)內(nèi)容和教學(xué)要求的認(rèn)識 本節(jié)課是一節(jié)探究性活動課,教學(xué)大綱上對數(shù)學(xué)活動課作了這樣的解釋:“數(shù)學(xué)活動課指在教師的指導(dǎo)下,通過學(xué)生自主活動,以獲得直接經(jīng)驗和培養(yǎng)實踐能力為主的課程。教育的目的在于彌補數(shù)學(xué)學(xué)科課程的不足,加強實踐環(huán)節(jié),重視數(shù)學(xué)思維的訓(xùn)練,培養(yǎng)學(xué)生的學(xué)習(xí)興趣,促進(jìn)學(xué)生志趣、個性、特長等自主和諧發(fā)展, 從而全面提高學(xué)生的數(shù)學(xué)素質(zhì)”。可見教學(xué)大綱把實習(xí)和開展探究性教學(xué)放在了重要的地位。

    二、說教法學(xué)法教法:本課教學(xué)內(nèi)容偏重于對各種水果的形狀和色彩運用的認(rèn)識和表現(xiàn)。由于學(xué)習(xí)內(nèi)容接近學(xué)生生活,因此,在教學(xué)中我采用直接體驗、引導(dǎo)發(fā)現(xiàn)法,作品欣賞的教學(xué)法進(jìn)行教學(xué),以便學(xué)生在生動活潑的情境中,感受美的過程,去發(fā)現(xiàn)美,創(chuàng)造美。
