第三階段：分班交流論證，歸納整理成文在學(xué)生分組搜集整理資料的基礎(chǔ)之上，我們又以班級為單位由核心組成員組織資料交流并展開討論，共同歸納整理，集體完成《常熟建設(shè)現(xiàn)代農(nóng)業(yè)科技園區(qū)可行性分析調(diào)查表》中的相關(guān)內(nèi)容，交給各自的指導(dǎo)老師修改。第四階段：分片走進園區(qū)，體驗總結(jié)反思我們本著“熟悉家鄉(xiāng)、就近考察”的原則把全年級的學(xué)生分成八組，分別到八個園區(qū)開展實地調(diào)查。組織他們聽園區(qū)領(lǐng)導(dǎo)或?qū)I(yè)人員介紹園區(qū)的建設(shè)情況和遠景規(guī)劃，深入田間地頭和溫室大棚參觀園區(qū)生產(chǎn)裝備和農(nóng)民勞動場景，開展園區(qū)勞動體驗，與園區(qū)農(nóng)民交談等系列活動。要求大家在體驗勞動、收獲快樂的同時，對照《常熟現(xiàn)代化農(nóng)業(yè)園區(qū)建設(shè)和發(fā)展情況調(diào)查表》的內(nèi)容逐一展開討論并認真填寫。在此基礎(chǔ)上，我們又要求各片的同學(xué)認真反思每個園區(qū)在發(fā)展過程中還有哪些不夠完美的地方和需要改進的建議。
人教版高中地理必修2南京的自行車是多了還是少了說課稿
在學(xué)生回答的基礎(chǔ)上進行歸納小結(jié)：發(fā)展城市公共交通? 明確道路分工? 合理規(guī)劃停車場? 減少出行距離? 錯開出行高峰? 加大城市道路建設(shè)? 進行科學(xué)合理的交通管理，重視智能交通系統(tǒng)的建設(shè)提問：這組同學(xué)在幻燈片中提到城市環(huán)境污染源主要有哪些？城市交通環(huán)境問題除了交通工具的尾氣排放帶來大氣污染外，還會給城市環(huán)境帶來什么問題？這組同學(xué)基本同意自行車多是加劇南京空氣污染的間接原因，你同意他們的觀點嗎？在學(xué)生回答的基礎(chǔ)上，教師進行歸納小結(jié)：自行車是一種綠色交通工具，既環(huán)保又經(jīng)濟。只有當(dāng)它在某些機動車和非機動車不分的地段，影響車輛行駛速度的時候，它才可能成為加劇空氣污染的間接原因。那么我們針對交通工具對環(huán)境造成的影響，除了這組同學(xué)提到的三點解決措施以外，我們還有什么要補充的解決方法嗎？

人教版新課標高中物理必修1彈性形變和彈力說課稿
在同一個直角坐標，做出兩個不同彈簧的F—X圖象，然后進行比較。圖象法處理數(shù)據(jù)更為直觀，更容易得出物理變化規(guī)律，且該種方法處理數(shù)據(jù)能更好地減小實驗的偶然誤差。最后老師歸納總結(jié)：得出胡克定律：F=KX(K為彈簧的頸度系數(shù))[設(shè)計意圖：在探究彈力的大小與形變的定量關(guān)系時，由學(xué)生進行猜想、實驗和得出規(guī)律，并利用信息技術(shù)計算機繪制F—X圖象，充分利用信息技術(shù)資源和物理學(xué)科的整合。能較好地體現(xiàn)以學(xué)生為主的新的教學(xué)理念。對探究實驗過程教師加以指導(dǎo)，使學(xué)生學(xué)會團結(jié)合作、學(xué)會探究物理規(guī)律；再加上熟練信息技術(shù)，更有效地提高學(xué)習(xí)效率。]（五）彈力的應(yīng)用（圖片，視頻播放：射箭）[設(shè)計意圖：讓學(xué)生知道產(chǎn)品設(shè)計離不開物理理論，做到從實踐到理論，再從理論到實踐的學(xué)習(xí)過程。]（六）開放式問題（視頻播放：撐桿跳高、跳水）；提出問題：通過本節(jié)內(nèi)容的學(xué)習(xí)，請同學(xué)們開放式地討論①從形變與彈力知識去思考，撐桿跳高運動員跳得這么高的主要原因是什么？②跳水運動員在空中滯空時間主要由哪方面決定？
