8、設(shè)隊(duì)伍貢獻(xiàn)新的血輪。5、 為彌補(bǔ)本院學(xué)生在校接受高等教育期間，各年級(jí)所有的專業(yè)課程均未采用原文（英文）教科書（text books）的不足與缺憾，也希望借助此項(xiàng)雙語課程的開設(shè)，能夠啟發(fā)學(xué)生們對(duì)于機(jī)械設(shè)計(jì)/理論力學(xué)/材料科學(xué)，以及機(jī)械工程與機(jī)械相關(guān)現(xiàn)代設(shè)計(jì)/制造技術(shù)相關(guān)專業(yè)英語的濃厚學(xué)習(xí)興趣，并能逐步引導(dǎo)學(xué)生自發(fā)性的走進(jìn)圖書館，去查詢各學(xué)科專業(yè)技術(shù)英文期刊、參考資料及原文科技雜志，為日后邁入考研及出國留學(xué)之路打下厚實(shí)的基礎(chǔ)。6、講授理論力學(xué)-靜力學(xué)篇（雙語教學(xué)課程），首先應(yīng)予重視下列幾點(diǎn)：1）學(xué)習(xí)理論力學(xué)-靜力學(xué)篇雙語教學(xué)課程，首重科技英語的熟練，除學(xué)習(xí)理論力學(xué)-靜力學(xué)篇相關(guān)的科技英語專業(yè)詞匯外

9、，也必須學(xué)習(xí)日常生活應(yīng)用相關(guān)的普通詞匯，而全部“美式英語”慣用語法的知識(shí)與技巧，在授課過程中亦當(dāng)然應(yīng)該有所側(cè)重； 2）在上述理論的基礎(chǔ)上，還必須學(xué)習(xí)一些有關(guān)理論力學(xué)同類學(xué)科的科技專業(yè)英語，以及翻譯為中文語句方面的基本理念和直譯技巧； 3）應(yīng)該要求學(xué)生更加關(guān)注本課程，除課堂內(nèi)力求理解教材之內(nèi)容外，平時(shí)應(yīng)該練習(xí)主動(dòng)的去廣泛的接觸與理論力學(xué)-靜力學(xué)篇課程相關(guān)的各種英文版科技期刊與參考文獻(xiàn)。 4）課后精選各章節(jié)段落附含的綜合應(yīng)用例題與習(xí)題，布置學(xué)生用心練習(xí)，并且記錄在作業(yè)簿上，作為日后期末考前復(fù)習(xí)資料的一部分，同時(shí)要求學(xué)生在做題目時(shí)務(wù)必嚴(yán)格作圖，尤其是“分離體的受力圖”，更借此培養(yǎng)學(xué)生的機(jī)械制圖能力。

10、教學(xué)重點(diǎn)難點(diǎn)教學(xué)重點(diǎn)：1、鑒于理論力學(xué)-靜力學(xué)篇雙語教學(xué)課程，所使用的專業(yè)英語詞匯與日常生活會(huì)話詞匯的迥異性，故針對(duì)機(jī)械/材料工程與現(xiàn)代機(jī)械設(shè)計(jì)/制造技術(shù)相關(guān)專業(yè)英語的每個(gè)教學(xué)單元課程，除了闡明物理與數(shù)學(xué)的概念及表示方式外，均先提示學(xué)生一般在中學(xué)時(shí)期已學(xué)習(xí)過詞匯的特殊用法，令學(xué)生在明瞭理論力學(xué)的同時(shí)對(duì)英語產(chǎn)生濃厚的學(xué)習(xí)興趣。 2、針對(duì)原文教材各單元的專業(yè)技術(shù)之物理及數(shù)學(xué)表示方式、專用語法和翻譯注釋，在開始授課前即進(jìn)行講解&導(dǎo)讀，并對(duì)現(xiàn)行有關(guān)理論力學(xué)-靜力學(xué)篇與機(jī)械/材料工程與現(xiàn)代機(jī)械設(shè)計(jì)/制造技術(shù)專業(yè)課程，滯后于當(dāng)今歐、美先進(jìn)的同類科技展的不足現(xiàn)象進(jìn)行彌補(bǔ)。 3、依照教材課文內(nèi)容進(jìn)行段

11、落重點(diǎn)式的講解，并提示學(xué)生關(guān)于理論力學(xué)-靜力學(xué)篇的科技性論文&報(bào)告的繕寫概要模式，同時(shí)布置課內(nèi)重點(diǎn)作業(yè)、登記累算個(gè)別學(xué)生的平時(shí)成績，繼而要求學(xué)生上課期間抄寫隨堂筆記，當(dāng)作課后實(shí)際作業(yè)以便日后計(jì)算平時(shí)成績。 4、學(xué)期課后考察方式則選采全球先進(jìn)的英語gre物理、數(shù)學(xué)測(cè)驗(yàn)?zāi)Ｊ竭M(jìn)行，令學(xué)生深感猶如參加cet四-六級(jí)考試模擬測(cè)試般，進(jìn)而括大面積、增廣范圍的吸收機(jī)械/材料工程與現(xiàn)代機(jī)械設(shè)計(jì)/制造技術(shù)相關(guān)專業(yè)英語知識(shí)，且使自身的英語水平必然相對(duì)提升。 5、針對(duì)機(jī)械/材料工程與現(xiàn)代機(jī)械設(shè)計(jì)/制造技術(shù)領(lǐng)域相關(guān)專業(yè)英語中的詞首字母縮略組合詞（acronyms）& 縮寫詞（abbreviation）

12、，均給予重點(diǎn)提示和強(qiáng)化記憶疏導(dǎo)，并時(shí)常做針對(duì)性的講解，且舉例說明詞首字母縮略組合詞(acronyms)，在專業(yè)英語范疇內(nèi)的實(shí)用性及前衛(wèi)性&特殊性及重要性；讓學(xué)生在學(xué)習(xí)過后立即可以運(yùn)用在“畢業(yè)設(shè)計(jì)”論文中，如此學(xué)生的主動(dòng)學(xué)習(xí)興趣自然高漲，積極性也將不斷提高。教學(xué)難點(diǎn)：1、由于理論力學(xué)-靜力學(xué)篇課程與現(xiàn)代機(jī)械設(shè)計(jì)/制造技術(shù)相關(guān)的專業(yè)英語，所涉及的領(lǐng)域過于廣泛，故經(jīng)常發(fā)生因課程內(nèi)容精辟必須耗時(shí)講解，而致授課時(shí)間難以掌控的情形或若對(duì)學(xué)生疑難多加解釋則必延誤課程進(jìn)度的情況時(shí)有發(fā)生，謹(jǐn)此建議：增加本課程的課時(shí)，并將之列為大二年級(jí)的必修課程，以便學(xué)生能夠充分、完整的學(xué)習(xí)本項(xiàng)專業(yè)英語課程。 2、授課時(shí)

13、將學(xué)生一般在初、高中時(shí)期已學(xué)習(xí)過的很多常態(tài)英語詞匯，技巧性的將其轉(zhuǎn)換為在機(jī)械/材料工程與現(xiàn)代機(jī)械設(shè)計(jì)/制造技術(shù)領(lǐng)域?qū)I(yè)英語中的特殊用法，而于解釋過程中，學(xué)生往往無法立即明瞭和接受，唯經(jīng)反復(fù)闡述、提示，方能獲得初步成效。3、對(duì)學(xué)生而言，由于其同時(shí)學(xué)習(xí)機(jī)械/材料工程與現(xiàn)代機(jī)械設(shè)計(jì)/制造技術(shù)的其他相關(guān)課程，均采用國內(nèi)自編中文教材因?yàn)椴糠志幷卟磺笊踅獾钠H觀念與過時(shí)理念，往往對(duì)學(xué)生造成想當(dāng)之困擾，使其對(duì)例常教學(xué)內(nèi)容與本項(xiàng)課程內(nèi)容的對(duì)應(yīng)性及配合性極難掌握，造成部分學(xué)生在學(xué)習(xí)專業(yè)英語的過程中，仍存有學(xué)習(xí)不適應(yīng)與理解沖突等缺憾現(xiàn)象。 4、為培養(yǎng)本科學(xué)生對(duì)本項(xiàng)理論力學(xué)-靜力學(xué)篇“雙語教學(xué)”課程的學(xué)習(xí)興趣，擬建

14、議：針對(duì)本院各專業(yè)科系的重點(diǎn)課程，均配比增開、實(shí)施各科專業(yè)的雙語教學(xué)課程，使學(xué)生能逐步自行參照中、英文教材對(duì)比研析，如此才能更有效的學(xué)習(xí)較先進(jìn)的科技知識(shí)及英語語法概念。 5、由于當(dāng)今全球已開發(fā)國家均盛行、通用“美式英語”，故欲與國際先進(jìn)科技接軌，就必須規(guī)劃全國的莘莘學(xué)子，全面展開學(xué)習(xí)先進(jìn)的“美式英語”；而目前國內(nèi)的“大學(xué)英語”教學(xué)則常年采用“英式英語”作為英文學(xué)習(xí)教材，以致當(dāng)學(xué)生面對(duì)本雙語課程的原文教材內(nèi)容時(shí)容易產(chǎn)生困惑，加以國內(nèi)許多資深的教學(xué)“專家”早已自行規(guī)整創(chuàng)建了一套“chinglish”，并且長年累積、持續(xù)的灌輸學(xué)生以錯(cuò)誤的英語學(xué)習(xí)觀念&語法意識(shí)及詞匯用法，也因此造成了本“雙語

15、課程”在授課過程中明顯出現(xiàn)“雙軌脫序”現(xiàn)象，所以務(wù)必要求學(xué)生全力配合授課老師對(duì)本雙語教學(xué)課程的相關(guān)要求，同時(shí)付出更多的努力與勤奮，如此學(xué)生的學(xué)習(xí)成效才能逐漸有所斬獲。 理論力學(xué)-靜力學(xué)篇（雙語教學(xué)課程） 課程教案授課時(shí)間第 一 周：周一、二 第 3、4 節(jié)；周三 第 5、6 節(jié)（單周課程）課次1 1授課方式（請(qǐng)打）理論課() 討論課() 實(shí)驗(yàn)課() 習(xí)題課() 其他()課時(shí)安排2hr/次 授課題目（教學(xué)章、節(jié)或主題）：第一單元：理論力學(xué)-靜力學(xué)篇 總綱概述unit 1：general principles主要教學(xué)方法與手段授課模式：理論力學(xué)-靜力學(xué)篇的原理&物理、數(shù)學(xué)表示法，及課堂面授

35、相關(guān)雙語教學(xué)，同時(shí)，可針對(duì)各科系專業(yè)的實(shí)際需求，自大學(xué)一、二年級(jí)起，即擇優(yōu)片面開設(shè)：微積分、工程數(shù)學(xué)、普通物理、普通化學(xué)、工程力學(xué)、線性代數(shù)、計(jì)算機(jī)基本原理等基礎(chǔ)學(xué)科與科系的專業(yè)學(xué)科之“專業(yè)英語”課程，俟全院兩屆本科學(xué)生整體學(xué)習(xí)后，再針對(duì)學(xué)生的受教程度及英語水平進(jìn)行全面評(píng)估，如此進(jìn)行深度化教學(xué)整改后，相信本院系全體老師的其他相關(guān)專業(yè)學(xué)科的普遍教學(xué)品質(zhì)與學(xué)生自身的整體素質(zhì)亦將獲得同步提升。2）學(xué)生整體到課比率&上課學(xué)習(xí)情緒現(xiàn)階段皆屬積極，且針對(duì)先進(jìn)“美式英語”教學(xué)的課程內(nèi)容充滿了求知的興趣，相信凡是愿意主動(dòng)投入心力學(xué)習(xí)的學(xué)生，相信無論是在個(gè)人英語程度、造詣方面和在理論力學(xué)及工程力學(xué)與材料

36、力學(xué)和現(xiàn)代機(jī)械設(shè)計(jì)、模具制造技術(shù)等領(lǐng)域之雙語教學(xué)課程專業(yè)知識(shí)的學(xué)習(xí)成效方面，必然將會(huì)逐步明顯提升并間接獲得顯著的學(xué)習(xí)成果。 3) 由于當(dāng)今全球已開發(fā)國家均盛行、通用“美式英語”，故欲與國際先進(jìn)科技接軌，就必須規(guī)劃全國的莘莘學(xué)子，全面展開學(xué)習(xí)先進(jìn)的“美式英語”；而目前國內(nèi)的“大學(xué)英語”教學(xué)則常年采用“英式英語”作為英文學(xué)習(xí)教材，以致當(dāng)學(xué)生面對(duì)本雙語課程的原文教材內(nèi)容時(shí)容易產(chǎn)生困惑，加以國內(nèi)許多資深的教學(xué)“專家”早已自行規(guī)整創(chuàng)建了一套中式的英式英語“chinglish”，并且長年累積、持續(xù)的灌輸學(xué)生以錯(cuò)誤的英語學(xué)習(xí)觀念&語法意識(shí)及詞匯用法，也因此造成了本“雙語課程”在授課過程中明顯出現(xiàn)“雙

37、軌脫序”現(xiàn)象，所以務(wù)必要求學(xué)生全力配合授課老師對(duì)本理論力學(xué)-靜力學(xué)篇雙語教學(xué)課程的相關(guān)要求，同時(shí)付出更多的努力與勤奮，如此學(xué)生的學(xué)習(xí)成效才能逐漸有所斬獲。 理論力學(xué)-靜力學(xué)篇（雙語教學(xué)課程） 課程教案授課時(shí)間第 二 周：周一、二 第 3、4 節(jié)；周三 第 5、6 節(jié)（雙周課程）課次2 2授課方式（請(qǐng)打）理論課() 討論課() 實(shí)驗(yàn)課（） 習(xí)題課() 其他（）課時(shí)安排2hr/次 授課題目（教學(xué)章、節(jié)或主題）：第二單元：金屬工程材料的熱處理unit 2：heat treatment of metals主要教學(xué)方法與手段授課模式：課堂面授（verbal instruction） 、詞匯疑惑澄清、專有
