42、理想的聽(tīng)課效果。聽(tīng)課最重要的是緊跟老師的思路，否則，教師講得再好，新知識(shí)也無(wú)法接受。如何跟上老師飯思路呢？以下的聽(tīng)課方法值得同學(xué)們學(xué)習(xí)：,一、“超前思考，比較聽(tīng)課”,什么叫“超前思考，比較聽(tīng)課”？簡(jiǎn)單地說(shuō)，就是同學(xué)們?cè)谏险n的時(shí)候不僅要跟著老師的思路走，還要力爭(zhēng)走在老師思路的前面，用自己的思路和老師的思路進(jìn)行對(duì)比，從而發(fā)現(xiàn)不同之處，優(yōu)化思維。,比如在講,《,林沖棒打洪教頭,》,一文，老師會(huì)提出一些問(wèn)題，如林沖當(dāng)時(shí)為什么要戴著枷鎖？林沖、洪教頭是什么關(guān)系？林沖為什么要棒打洪教頭？,??????,,老師沒(méi)提了一個(gè)問(wèn)題，同學(xué)們就應(yīng)當(dāng)立即主動(dòng)地去思考，積極地尋找答案，然后和老師的解答進(jìn)行比較。通過(guò)超前思

43、考，可以把注意力集中在對(duì)這些“難點(diǎn)”的理解上，保證“好鋼用在刀刃上”，從而避免了沒(méi)有重點(diǎn)的泛泛而聽(tīng)。通過(guò)將自己的思考跟老師的講解做比較，還可以發(fā)現(xiàn)自己對(duì)新知識(shí)理解的不妥之處，及時(shí)消除知識(shí)的“隱患”。,二、同步聽(tīng)課法,有些同學(xué)在聽(tīng)課的過(guò)程中常碰到這樣的問(wèn)題，比如老師講到一道很難的題目時(shí)，同學(xué)們聽(tīng)課的思路就“卡殼“了，無(wú)法再跟上老師的思路。這時(shí)候該怎么辦呢？,如果“卡殼”的內(nèi)容是老師講的某一句話或某一個(gè)具體問(wèn)題，同學(xué)們應(yīng)馬上舉手提問(wèn)，爭(zhēng)取讓老師解釋得在透徹些、明白些。,如果“卡殼”的內(nèi)容是公式、定理、定律，而接下去就要用它去解決問(wèn)題，這種情況下大家應(yīng)當(dāng)先承認(rèn)老師給出的結(jié)論（公式或定律）并非繼續(xù)聽(tīng)下去，先把問(wèn)題記下來(lái)，到課后再慢慢弄懂它。,尖子生好方法,:,聽(tīng)課時(shí)應(yīng)該始終跟著老師的節(jié)奏，要善于抓住老師講解中的關(guān)鍵詞，構(gòu)建自己的知識(shí)結(jié)構(gòu)。利用老師講課的間隙，猜想老師還會(huì)講什么，會(huì)怎樣講，怎樣講會(huì)更好，如果讓我來(lái)講，我會(huì)怎樣講。這種方法適合于聽(tīng)課容易分心的同學(xué)。,2024/12/12,精選最新中小學(xué)教學(xué)課件,43,編后語(yǔ)有的同學(xué)聽(tīng)課時(shí)容易走神，常常聽(tīng)著聽(tīng)著心思就不知道溜到哪,thank you!,2024/12/12,精選最新中小學(xué)教學(xué)課件,44,thank you!2023/9/25精選最新中小學(xué)教學(xué)課件,
