46、考。教育見習(xí)實(shí)踐過程：聽課。教育見習(xí)的主要目的是讓學(xué)生在指導(dǎo)教師的引導(dǎo)下，觀摩教師上課方法、技巧等。聽課是教育見習(xí)的主要內(nèi)容。我院規(guī)定在一周的見習(xí)中需完成至少6課的見習(xí)任務(wù)。我在教師的安排指導(dǎo)下，分別對(duì)高一、高二物理專業(yè)課型為主，其他課型齊頭的方式，積極主動(dòng)的完成了聽課任務(wù)，收到良好的效果。我聽的第一節(jié)課是高二（8）班，這是一個(gè)平衡班，水平不如實(shí)驗(yàn)班高。在上課前?？迫卫蠋熞呀?jīng)跟我說了這個(gè)班的紀(jì)律是比較差的，而且成績(jī)也不是很好。在我聽課期間，確實(shí)有幾個(gè)學(xué)生在課堂上說話，但是我發(fā)現(xiàn)了一個(gè)有趣的現(xiàn)象，這個(gè)現(xiàn)象我在往后的幾個(gè)班都發(fā)現(xiàn)了，就是絕大部分的學(xué)生的學(xué)習(xí)熱情都好高漲，積極舉手發(fā)言，積極參與課堂活動(dòng)。我跟老師們提起這個(gè)現(xiàn)象的時(shí)候，科任老師就跟我說，一個(gè)班里不可能所有的學(xué)生都能全神貫注地聽完一節(jié)課，所以作為一名教師，應(yīng)該想辦法吸引學(xué)生的注意力，調(diào)動(dòng)的積極性，比如可以以小組為單位，以搶答計(jì)分的形式調(diào)動(dòng)學(xué)生的積極性，這樣課堂氣氛就會(huì)活躍起來了。在為期兩周的見習(xí)工作中，我真的有很大的感觸，我第一次感受到自己已經(jīng)從一名學(xué)生向一名教師靠近，走在校園里，每當(dāng)有學(xué)生叫我一聲老師，我在感到無比自豪的同時(shí)，還感受到了自己的責(zé)任。見習(xí)工作結(jié)束了，我要回到學(xué)校繼續(xù)我的學(xué)習(xí)了，但是我會(huì)好好記住我從*中學(xué)學(xué)到
