（1）交通運(yùn)輸布局的任務(wù)

（2）交通運(yùn)輸布局的目的

這兩個(gè)內(nèi)容直接可在課本中找到，可讓學(xué)生自主找到并回答，教師加以展示即可。

（3）影響交通運(yùn)輸布局的因素

包括兩大方面，社會(huì)經(jīng)濟(jì)因素和自然因素，讓學(xué)生結(jié)合課本自主先討論、總結(jié)，教師再加以解釋?zhuān)叨己苤匾壳吧鐣?huì)經(jīng)濟(jì)因素影響日趨明顯。

（4）交通運(yùn)輸布局的原則

堅(jiān)持原則，課本中有所體現(xiàn)，課件通過(guò)圖示加深印象。

結(jié)合影響交通運(yùn)輸布局的因素和原則，在宏觀決策和微觀選線(xiàn)方面進(jìn)行升華，更好地幫助學(xué)生解決選線(xiàn)要考慮的因素，提高解題準(zhǔn)確率。

（5）

交通運(yùn)輸布局的變化和影響

根據(jù)課本內(nèi)容簡(jiǎn)單再現(xiàn)即可。

[活動(dòng)探究]

西成高鐵修建考慮的最主要因素是什么？

西成高鐵克服穿越山嶺、坡道長(zhǎng)的修建困難，且實(shí)現(xiàn)了4G全覆蓋，這里充分體現(xiàn)了我國(guó)高鐵修建技術(shù)的提高，也是我國(guó)經(jīng)濟(jì)水平提高的體現(xiàn)，當(dāng)然，此線(xiàn)大大縮短了南北（成都到陜西）的距離，節(jié)省了時(shí)間，連接了沿線(xiàn)各地，也將帶來(lái)南北溝通加強(qiáng)，經(jīng)濟(jì)持續(xù)發(fā)展的好處。

2．交通運(yùn)輸需求與交通運(yùn)輸布局

（1）交通運(yùn)輸需求量與交通運(yùn)輸布局的影響

交通運(yùn)輸需求量的大小，影響了交通線(xiàn)標(biāo)準(zhǔn)的高低，場(chǎng)站規(guī)模的大小。比如，北京作為首都，其航站點(diǎn)會(huì)更大，疏導(dǎo)的交通線(xiàn)也更多。

（2）區(qū)域發(fā)展?fàn)顩r對(duì)交通運(yùn)輸布局的影響

在一條線(xiàn)路的布局中，重點(diǎn)關(guān)注的是需求量大的點(diǎn)和點(diǎn)，所以一個(gè)區(qū)域發(fā)展?fàn)顩r很大程度影響了交通運(yùn)輸線(xiàn)的布局和站點(diǎn)的設(shè)置。

[活動(dòng)探究]

廣東省省會(huì)廣州地鐵線(xiàn)的增設(shè)考慮的主要因素是什么？

所選擇的地鐵線(xiàn)是客流量大，即需求量大的線(xiàn)路和站點(diǎn)。而從修建的工期預(yù)估也可以看出經(jīng)濟(jì)發(fā)展。

（3）交通運(yùn)輸需求差異對(duì)交通布局的影響

a.

充分發(fā)揮不同交通運(yùn)輸方式的特點(diǎn)，回顧不同交通運(yùn)輸方式的優(yōu)缺點(diǎn)（點(diǎn)擊云朵鏈接下一張PPT，觀看完畢繼續(xù)往下一張PPT）

以課本4.4上海虹橋綜合交通樞紐平面示意圖，其陸空便捷的多種交通帶來(lái)便捷換乘，轉(zhuǎn)運(yùn)效率很高（點(diǎn)擊箭頭回到（3）PPT，得出“交通運(yùn)輸布局注意不同運(yùn)輸方式的銜接和轉(zhuǎn)運(yùn)效率”的結(jié)論）

b.

注意不同運(yùn)輸方式直接的銜接和轉(zhuǎn)運(yùn)效率，當(dāng)然，要考慮客或物的實(shí)際性，綜合實(shí)際考慮。

（4）區(qū)域交通運(yùn)輸需求增長(zhǎng)的特點(diǎn)，決定了區(qū)域交通運(yùn)輸布局變化的特點(diǎn)

（5）區(qū)域交通運(yùn)輸需求分布的特點(diǎn)，決定了區(qū)域交通運(yùn)輸布局的特點(diǎn)

當(dāng)一個(gè)區(qū)域的需求發(fā)生變化，那么其線(xiàn)路、站點(diǎn)的布局也會(huì)相應(yīng)變化。而一個(gè)區(qū)域需求分布也就決定了交通運(yùn)輸布局。

（點(diǎn)擊箭頭圖標(biāo)鏈接到活動(dòng)探究）

[活動(dòng)探究]

分析舟山群島新區(qū)成為我國(guó)鐵礦砂等大宗商品重要中轉(zhuǎn)基地的主要原因。

解析：舟山群島新區(qū)港口航道深、岸線(xiàn)長(zhǎng)、有利于大型船舶停泊；長(zhǎng)江中下游地區(qū)鐵礦砂等大宗商品進(jìn)口量大，多選擇水運(yùn)中轉(zhuǎn)。

3．資金與交通運(yùn)輸布局

（1）經(jīng)濟(jì)發(fā)展水平和交通運(yùn)輸布局的關(guān)系

經(jīng)濟(jì)發(fā)達(dá)與落后地區(qū)，交通線(xiàn)、站的疏密程度不同，質(zhì)量高低有差別。

（2）區(qū)域經(jīng)濟(jì)發(fā)展對(duì)交通運(yùn)輸布局的影響

一個(gè)區(qū)域經(jīng)濟(jì)水平提高了，有了足夠的資金，就可以推動(dòng)技術(shù)攻關(guān)等，受自然條件的限制也就減弱了。

結(jié)合課本84頁(yè)青藏高原的熱棒和滬昆高鐵貴州段隧道和橋梁相連，技術(shù)要求高、施工難度大，建設(shè)成本高。從高原建設(shè)成本高而過(guò)渡到平原建設(shè)成本一定低的思考。

[活動(dòng)探究]

在平原地區(qū)修建交通線(xiàn)成本一定低嗎？

辨證看此問(wèn)題，一般而言成本較低，但要考慮如果是像長(zhǎng)江中下游地區(qū)這樣河網(wǎng)密布、有大量農(nóng)田的平原，則需要建設(shè)橋梁，建設(shè)成本會(huì)增加。

三、課堂練習(xí)

1、讀某區(qū)域示意圖，回答1-2題。

（1）據(jù)圖分析，制約a地區(qū)發(fā)展交通運(yùn)輸業(yè)的主要因素是（

）

A.氣候

B.地形

C.河流

D.資源

（2）若計(jì)劃修建由a城鎮(zhèn)至c城鎮(zhèn)的公路，則四條線(xiàn)路中的最優(yōu)線(xiàn)路及理由

分別是（

）

A.

①線(xiàn)路

地勢(shì)起伏最小

B.②線(xiàn)路

路程最短

C.

③線(xiàn)路

兼顧b城鎮(zhèn)

D.

④線(xiàn)路

連接城鎮(zhèn)最多

解析:（1）B

（2）D

第（1）題，從圖中可以看出，a地區(qū)被山地包圍，修建道路的難度較大，故地形成為約該地發(fā)展交通運(yùn)輸業(yè)的主要因素。

第（2）題，從圖中可以看出，通過(guò)①線(xiàn)路連接a和c，經(jīng)過(guò)的城鎮(zhèn)少。不利于居民出行。不是最優(yōu)線(xiàn)路；

通過(guò)②線(xiàn)路連接a和c，采取直線(xiàn)直接穿過(guò)山地，工程量大，修建難度大、成本高，并且經(jīng)過(guò)的城鎮(zhèn)更少，不是最優(yōu)線(xiàn)路；

通過(guò)③線(xiàn)路連接a和c，雖然經(jīng)過(guò)了多個(gè)城鎮(zhèn)，但是直接穿過(guò)山地，工程量大，修建難度大，成本高，不是最優(yōu)線(xiàn)路。

通過(guò)④線(xiàn)連接a和c，不僅能夠盡可能多地連接城鎮(zhèn)，方便居民出行，而且盡量避開(kāi)了山地陡坡，修建難度較小，工程量較小，是最優(yōu)線(xiàn)路。

2、鄭渝(鄭州至重慶)鐵路是我國(guó)高速鐵路網(wǎng)規(guī)劃的重要線(xiàn)路，對(duì)促進(jìn)兩地及沿線(xiàn)地區(qū)社會(huì)經(jīng)濟(jì)發(fā)展方面具有重要的意義。下面為“鄭渝高速鐵路規(guī)劃圖”，初步規(guī)劃有①線(xiàn)、②線(xiàn)兩種方案。完成下列問(wèn)題。

(1)

對(duì)規(guī)劃中①、②兩條線(xiàn)路，你認(rèn)為哪一條更合理？簡(jiǎn)述其理由。

(2)

簡(jiǎn)述鄭渝高速鐵路建成后對(duì)甲城發(fā)展的積極意義。

解析：考查學(xué)生對(duì)交通線(xiàn)選擇考慮因素的掌握。

見(jiàn)PPT（其中方法闡述中箭頭鏈接到宏觀和微觀因素，在微觀選線(xiàn)PPT右下角箭頭鏈到答案）。

四、課堂總結(jié)

讓學(xué)生通過(guò)樹(shù)枝狀結(jié)構(gòu)進(jìn)行回憶，回顧本節(jié)重要知識(shí)。

五、布置作業(yè)

第8篇

關(guān)鍵詞：人體寄生蟲(chóng)學(xué)；博客；案例教學(xué)

寄生蟲(chóng)病仍是目前嚴(yán)重威脅人類(lèi)健康的疾病之一。近年全國(guó)范圍的寄生蟲(chóng)感染調(diào)查發(fā)現(xiàn)，我國(guó)人體寄生蟲(chóng)有229種，其中線(xiàn)蟲(chóng)35種，吸蟲(chóng)47種，絳蟲(chóng)16種，原蟲(chóng)41種，其它寄生動(dòng)物90種[1]。基于這種流行現(xiàn)狀，在醫(yī)學(xué)寄生蟲(chóng)學(xué)教學(xué)中引入臨床案例分析可不容緩。然而，當(dāng)前寧夏醫(yī)科大學(xué)臨床專(zhuān)業(yè)本科人體寄生蟲(chóng)課程教學(xué)時(shí)數(shù)嚴(yán)重壓縮，總學(xué)時(shí)48學(xué)時(shí)，其中理論課20 學(xué)時(shí)，實(shí)驗(yàn)課（講習(xí)課）28 學(xué)時(shí)，可見(jiàn)課程教學(xué)任務(wù)很重，在這種情況下，傳統(tǒng)的以教師為主體的滿(mǎn)堂灌已遠(yuǎn)遠(yuǎn)不能滿(mǎn)足時(shí)展之需。只有探尋得力的教學(xué)輔助工具以及有效教學(xué)方法才能解決問(wèn)題。

博客（BLOG）是一種新興的交流方式。隨著網(wǎng)絡(luò)技術(shù)的迅猛發(fā)展，博客、微博客等相繼成為重要的信息傳播工具[2]。其教育功能逐漸得到教育工作者的重視并被引入到教學(xué)中。基于以上情況，近幾年來(lái)我們教研室開(kāi)展了適合我校實(shí)情的人體寄生蟲(chóng)學(xué)教學(xué)改革，成功地將傳統(tǒng)授課方式結(jié)合博客輔助案例教學(xué)引入課堂，介紹如下。

1教學(xué)的實(shí)施過(guò)程

1.1建立病例庫(kù)及精心編寫(xiě)案例 依據(jù)教學(xué)大綱和教學(xué)內(nèi)容，認(rèn)真搜集整理寄生蟲(chóng)的典型病例，盡可能選擇能與教學(xué)內(nèi)容對(duì)應(yīng)的病例（尤其是西北地區(qū)特有的病例） 作為重點(diǎn)內(nèi)容。積極與周?chē)t(yī)院聯(lián)系，及時(shí)收集新病例，實(shí)時(shí)關(guān)注文獻(xiàn)報(bào)道的國(guó)內(nèi)及區(qū)內(nèi)新發(fā)病例，使病例庫(kù)得以更新和不斷完善。

1.2建立以學(xué)生為中心的教學(xué)博客 具體來(lái)講，人體寄生蟲(chóng)學(xué)博客至少可以包括以下內(nèi)容：

1.2.1課程信息 開(kāi)學(xué)前將本課程的教學(xué)大綱、教學(xué)計(jì)劃以及考核方式等信息上傳到博客上，便于學(xué)生從整體上把握本課程。

1.2.2課前準(zhǔn)備 每次上課前1w，上傳本次課的教學(xué)目標(biāo)、主要內(nèi)容、重點(diǎn)難點(diǎn)以及與教學(xué)內(nèi)容相對(duì)應(yīng)病例與問(wèn)題。教師根據(jù)本課程的教學(xué)大綱和培養(yǎng)目標(biāo)，選出典型的4～6 種臨床寄生蟲(chóng)病例，并對(duì)每一個(gè)病例提出3～5道綜合性問(wèn)題，對(duì)典型病例的一些問(wèn)題，利用教材、參考書(shū)、教學(xué)軟件及互聯(lián)網(wǎng)等進(jìn)行課前準(zhǔn)備。

1.3傳統(tǒng)教學(xué)結(jié)合案例分析教學(xué)的實(shí)施過(guò)程

1.3.1改進(jìn)授課方式 理論課與實(shí)驗(yàn)課不分開(kāi)，均在實(shí)驗(yàn)室開(kāi)展。每周1次課，每次5學(xué)時(shí)。每次課由一名教師主講，一名教師輔導(dǎo)。

1.3.2改良考核方式 我們以往的考核方式為期末卷面成績(jī)占70%，實(shí)驗(yàn)報(bào)告20%，平時(shí)成績(jī)10%。引入病例討論后，需改進(jìn)考核方式，以反映學(xué)生主動(dòng)學(xué)習(xí)和綜合應(yīng)用各科知識(shí)解決臨床實(shí)際問(wèn)題的能力。 因此，在理論考試卷面中增加了案例分析 診斷等密切聯(lián)系臨床的題例，平時(shí)成績(jī)主要反映學(xué)生分析病例、共同討論時(shí)的表現(xiàn)。考核方式改為期末卷面成績(jī)占60%，實(shí)驗(yàn)報(bào)告占20%，平時(shí)成績(jī)占20%。

1.3.3課堂教學(xué)過(guò)程 ①主講教師先用1學(xué)時(shí)（40min）講本次課所有寄生蟲(chóng)的形態(tài)結(jié)構(gòu)，然后學(xué)生用1學(xué)時(shí)觀察標(biāo)本并繪制圖，完成實(shí)驗(yàn)報(bào)告。主講教師再用1學(xué)時(shí)講解次課所有寄生蟲(chóng)的生活史及其致病特點(diǎn)，剩余2個(gè)學(xué)時(shí)用來(lái)討論案例及問(wèn)題。②建立教學(xué)小組和討論問(wèn)題：2012級(jí)臨床卓越醫(yī)師班共36名學(xué)生，以學(xué)生自愿結(jié)合老師協(xié)調(diào)方式分為4個(gè)教學(xué)小組，主講老師和輔導(dǎo)教師各負(fù)責(zé)兩個(gè)小組。針對(duì)教師提出的典型病例的一些問(wèn)題，同組同學(xué)進(jìn)行討論。③老師回答問(wèn)題及效果觀察：教師對(duì)學(xué)生的解答內(nèi)容進(jìn)行答疑，指出學(xué)生答題中存在的問(wèn)題，教師根據(jù)每位學(xué)生的實(shí)際表現(xiàn)，給出本次課的平時(shí)成績(jī)。

2教學(xué)效果分析評(píng)價(jià)

實(shí)驗(yàn)組與對(duì)照組在同一學(xué)期嚴(yán)格按照教學(xué)計(jì)劃進(jìn)行教學(xué)。課程結(jié)束后，理論課考試采用標(biāo)準(zhǔn)化試卷筆試，以?xún)?yōu)秀，良好，及格，不及格四個(gè)等級(jí)記錄；實(shí)驗(yàn)課成績(jī)是10次實(shí)驗(yàn)報(bào)告分?jǐn)?shù)的總和，同樣以?xún)?yōu)秀，良好，及格，不及格四個(gè)等級(jí)記錄。實(shí)驗(yàn)組除理論課成績(jī)和實(shí)驗(yàn)課成績(jī)外，還有平時(shí)成績(jī)。在教學(xué)效果比較分析時(shí)只采用前兩項(xiàng)，見(jiàn)表1。

表1的分析結(jié)果表明，實(shí)驗(yàn)組的理論與實(shí)驗(yàn)考核的優(yōu)秀率與不及格率均優(yōu)于對(duì)照組。說(shuō)明案例教學(xué)不僅能加深學(xué)生對(duì)寄生蟲(chóng)病的理解，而且能夠培養(yǎng)學(xué)生處理臨床實(shí)際問(wèn)題的能力。博客輔助案例教學(xué)可以激發(fā)學(xué)生的興趣和學(xué)習(xí)熱情，調(diào)動(dòng)學(xué)生學(xué)習(xí)的主動(dòng)性和積極性，培養(yǎng)學(xué)生自主學(xué)習(xí)的能力及發(fā)現(xiàn)問(wèn)題和解決問(wèn)題的能力。有利于培養(yǎng)學(xué)生的綜合性思維以及團(tuán)隊(duì)合作能力。

3結(jié)論

人體寄生蟲(chóng)學(xué)是一門(mén)與臨床緊密聯(lián)系的醫(yī)學(xué)基礎(chǔ)課。通過(guò)博客這種重要的交流和溝通工具，可以彌補(bǔ)課堂教學(xué)中無(wú)法大量進(jìn)行案例討論的局限，使課堂教學(xué)得以擴(kuò)展，也使學(xué)生能夠隨時(shí)表達(dá)學(xué)習(xí)心得以及與主講教師探討某些問(wèn)題，形成一個(gè)大家共享的學(xué)習(xí)平臺(tái)。

總之，借助先進(jìn)的信息傳播工具，在傳統(tǒng)的理論教學(xué)的基礎(chǔ)上結(jié)合病例討論，是適應(yīng)現(xiàn)代醫(yī)學(xué)教育模式的需要，也是提高教學(xué)質(zhì)量及醫(yī)學(xué)人才實(shí)踐能力的迫切需要。
