人教版高中地理選修3第五章第一節(jié)設(shè)計(jì)旅游活動(dòng)教案
點(diǎn)撥：旅游地旅游資源的特色不同，可以安排的旅游活動(dòng)是不一樣的，直接影響對(duì)旅游者的吸引力。因此，出游前首先就需要收集旅游地旅游資源的類(lèi)型、主要游覽景區(qū)、景點(diǎn)的特色等情況。旅游地的時(shí)空可達(dá)性直接關(guān)系到旅游者從出發(fā)地到旅游地，然后再返回出發(fā)地的費(fèi)用和時(shí)間。一般來(lái)說(shuō)，居住地與旅游地之間的空間距離過(guò)大，會(huì)使旅行的時(shí)間過(guò)長(zhǎng)、旅行費(fèi)用過(guò)高，經(jīng)濟(jì)距離增加，相應(yīng)地降低了旅游者的出游能力。而居住地與旅游地相距遙遠(yuǎn)，也意味著兩地之間巨大的環(huán)境差異，這會(huì)增加對(duì)游客的吸引力。旅游服務(wù)設(shè)施和條件，如旅游交通方式及工具、旅游住宿條件、旅游餐飲的種類(lèi)和標(biāo)準(zhǔn)、導(dǎo)游服務(wù)、旅行費(fèi)用等信息也都在一定程度上影響著游客的選擇。圖5．3西藏布達(dá)拉宮和圖5．4云南香格里拉兩幅圖片顯示了西藏布達(dá)拉宮、云南香格里拉與眾不同的優(yōu)美景觀，吸引了眾多的游客前來(lái)觀光旅游，成為近年來(lái)國(guó)內(nèi)旅游的熱點(diǎn)。
北師大初中數(shù)學(xué)九年級(jí)上冊(cè)比例的性質(zhì)1教案
若a，b，c都是不等于零的數(shù)，且a＋bc＝b＋ca＝c＋ab＝k，求k的值.解：當(dāng)a＋b＋c≠0時(shí)，由a＋bc＝b＋ca＝c＋ab＝k，得a＋b＋b＋c＋c＋aa＋b＋c＝k，則k＝2（a＋b＋c）a＋b＋c＝2；當(dāng)a＋b＋c＝0時(shí)，則有a＋b＝－c.此時(shí)k＝a＋bc＝－cc＝－1.綜上所述，k的值是2或－1.易錯(cuò)提醒：運(yùn)用等比性質(zhì)的條件是分母之和不等于0，往往忽視這一隱含條件而出錯(cuò).本題題目中并沒(méi)有交代a＋b＋c≠0，所以應(yīng)分兩種情況討論，容易出現(xiàn)的錯(cuò)誤是忽略討論a＋b＋c＝0這種情況.三、板書(shū)設(shè)計(jì)比例的性質(zhì)基本性質(zhì)：如果ab＝cd，那么ad＝bc如果ad＝bc（a，b，c，d都不等于0），那么ab＝cd等比性質(zhì)：如果ab＝cd＝…＝mn（b＋d＋…＋n≠0）， 那么a＋c＋…＋mb＋d＋…＋n＝ab經(jīng)歷比例的性質(zhì)的探索過(guò)程，體會(huì)類(lèi)比的思想，提高學(xué)生探究、歸納的能力.通過(guò)問(wèn)題情境的創(chuàng)設(shè)和解決過(guò)程進(jìn)一步體會(huì)數(shù)學(xué)與生活的緊密聯(lián)系，體會(huì)數(shù)學(xué)的思維方式，增強(qiáng)學(xué)習(xí)數(shù)學(xué)的興趣.
北師大初中數(shù)學(xué)九年級(jí)上冊(cè)矩形的判定1教案
在△AEF和△DEC中，∠AFE＝∠DCE，∠AEF＝∠DEC，AE＝DE，∴△AEF≌△DEC(AAS)，∴AF＝DC.∵AF＝BD，∴BD＝DC；(2)當(dāng)△ABC滿足AB＝AC時(shí)，四邊形AFBD是矩形．理由如下：∵AF∥BD，AF＝BD，∴四邊形AFBD是平行四邊形．∴AB＝AC，BD＝DC，∴∠ADB＝90°.∴四邊形AFBD是矩形．方法總結(jié)：本題綜合考查了矩形和全等三角形的判定方法，明確有一個(gè)角是直角的平行四邊形是矩形是解本題的關(guān)鍵．三、板書(shū)設(shè)計(jì)矩形的判定對(duì)角線相等的平行四邊形是矩形三個(gè)角是直角的四邊形是矩形有一個(gè)角是直角的平行四邊形是矩形（定義）通過(guò)探索與交流，得出矩形的判定定理，使學(xué)生親身經(jīng)歷知識(shí)的發(fā)生過(guò)程，并會(huì)運(yùn)用定理解決相關(guān)問(wèn)題．通過(guò)開(kāi)放式命題，嘗試從不同角度尋求解決問(wèn)題的方法．通過(guò)動(dòng)手實(shí)踐、合作探索、小組交流，培養(yǎng)學(xué)生的邏輯推理能力.
