19、式，實(shí)現(xiàn)任務(wù)的目標(biāo)，感受成功：在學(xué)習(xí)過程中進(jìn)行情感和策略調(diào)整，以形成積極的學(xué)習(xí)態(tài)度，促進(jìn)語言實(shí)際運(yùn)用能力的提高。采用師生交流方式導(dǎo)入自然親切，拉近了師生之間的情感距離，營造出寬松的學(xué)習(xí)氣氛，同時讓學(xué)生了解身勢語的有關(guān)內(nèi)容。根據(jù)教師提出的一系列問題，學(xué)生自主搜索與身勢語相關(guān)的信息資料，然后以個人探究和合作學(xué)習(xí)相結(jié)合，并以各種的形式展示交流成果。本人這節(jié)課安排探究和討論過程中的觀點(diǎn)匯總等形式鼓勵學(xué)生借助小組活動的形式來合作，表達(dá)，思考，能使學(xué)生在活動中互相學(xué)習(xí)、互相幫助，互相鼓勵，體驗(yàn)集體榮譽(yù)感和成就感，發(fā)展合作精神。通過師生交流與總結(jié)這一形式引發(fā)學(xué)生對身勢語的深入思考，進(jìn)一步深化主題。 八、教學(xué)

20、反思 1.在通過教師設(shè)問，學(xué)生思考回答從而完成學(xué)生知識點(diǎn)的自我積累時，我感到設(shè)問的問題較少，而在確定的幾個主要問題上，學(xué)生回答較為準(zhǔn)確，從而缺少了學(xué)生深入的思考與學(xué)習(xí)方法的體驗(yàn)。在對文章大意歸納時，給學(xué)生時間不足，從而缺少學(xué)生根據(jù)文章信息得出大意事的充分思考。在訓(xùn)練學(xué)生對信息加工與處理能力時，活動設(shè)計目的明確，但量不足，所獲得的體驗(yàn)未能的到再體驗(yàn)與提高。2.用自己的話去完成對課文的復(fù)述這個練習(xí)教學(xué)中發(fā)現(xiàn)并不是學(xué)生的難點(diǎn)，這是因?yàn)榭赵O(shè)計的太簡單。而對學(xué)生自我能力的培養(yǎng)上，本節(jié)課起到了方法的指導(dǎo)作用。3.教學(xué)方法設(shè)計合理，運(yùn)用恰當(dāng)。但感到方法上缺少新意。在本堂課的教學(xué)理念上做到了面向全體學(xué)生，評價做到了注重發(fā)展性評價。但在教學(xué)設(shè)計中未能體現(xiàn)出來。九、板書設(shè)計Module4
