2、講授新課：在講授新課的過程中，我突出教材的重點，明了地分析教材的難點。還根據(jù)教材的特點，學生的實際、教師的特長，以及教學設備的情況，我選擇了多媒體的教學手段。這些教學手段的運用可以使抽象的知識具體化，枯燥的知識生動化，乏味的知識興趣化。還重視教材中的疑問，適當對題目進行引申,使它的作用更加突出，有利于學生對知識的串聯(lián)、積累、加工，從而達到舉一反三的效果。3、課堂小結，強化認識：課堂小結，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學生的素質(zhì)；簡單扼要的課堂小結，可使學生更深刻地理解政治理論在實際生活中的應用，并且逐漸地培養(yǎng)學生具有良好的個性。4、板書設計我比較注重直觀、系統(tǒng)的板書設計，還及時地體現(xiàn)教材中的知識點，以便于學生能夠理解掌握。
人教版高中地理必修1第二章第四節(jié)全球氣候變化教案
氣候變化對健康的影響 氣候變化對人體健康的不良影響是不難發(fā)現(xiàn)的：熱浪沖擊頻繁加重可致死亡率及某些疾病、特別是心臟呼吸系統(tǒng)疾病發(fā)病率增加；對氣候變化敏感的傳染性疾病如瘧疾和登革熱的傳播范圍可能增加。極端氣候事件, 如干旱、水災、暴風雨等, 使死亡率、傷殘率及傳染病疾病率上升, 并增加社會心理壓力。某些媒介疾病的加重也可能與氣候變化有間接的關系, 如瘧疾是通過蚊子傳播的疾病,氣候變化可能使某些變暖地區(qū)的蚊子數(shù)目增加, 從而加重了瘧疾的發(fā)生。我國1994年瘧疾的發(fā)病率為5.3408/10萬, 居全國法定傳染病的第六位。血吸蟲病的發(fā)展與高溫及灌溉系統(tǒng)的擴增有關。我國1994年南方12省市血吸蟲病患者的檢出率高達3.67%，不能忽視氣候變化對此的可能影響。還有一些疾病，如睡眠病、登革熱、黑熱病等也有與氣候關系的報道。另外, CO2、一些空氣污染物如氮氧化物、臭氧等可增加過敏疾患及心臟呼吸系統(tǒng)疾病和死亡。
人教版新課標高中物理必修1牛頓第二定律教案2篇
1．這節(jié)課以實驗為依據(jù)，采用控制變量的方法進行研究。這一方法今后在電學、熱學的研究中還要用到。我們根據(jù)已掌握的知識設計實驗、探索規(guī)律是物體研究的重要方法。2．定義力的單位“牛頓”使得k=1，得到牛頓第二定律的簡單形式F=ma。使用簡捷的數(shù)學語言表達物理規(guī)律是物理學的特征之一，但應知道它所對應的文字內(nèi)容和意義。3．牛頓第二定律概括了運動和力的關系。物體所受合外力恒定，其加速度恒定；合外力為零，加速度為零。即合外力決定了加速度，而加速度影響著物體的運動情況。因此，牛頓第二定律是把前兩章力和物體的運動構成一個整體，其中的紐帶就是加速度。四、評價方案及說明1、對科學知識與技能的評價要注重科學內(nèi)容的理解與應用，而不是單純記憶。技能的評價目標包括觀察技能、實驗技能等方面。對科學的技能的評價要盡量融合在科學探究過程的情景中。對科學知識的評價主要從兩方面，一是根據(jù)學生診斷性練習；二是通過學生作業(yè)反映學生掌握情況。

人教版高中地理必修1第二章第四節(jié)全球氣候變化說課稿
（一）教材的地位與作用本節(jié)教材包括三方面的內(nèi)容，（1）全球氣候在不斷變化之中。（2）全球氣候變化的可能影響。（3）氣候變化的適應對策三方面說明氣候變化及其對人類活動的影響。從標準的要求看，學習的重點不在全球氣候變化本身，而是把全球氣候變化看作是客觀存在的事實，從而探討全球氣候變化對地理環(huán)境及人類活動的影響。從資料中可以看出本節(jié)教學內(nèi)容涵蓋的時空跨度非常大，思維的鏈索很長很廣，許多問題涉及到學科的前沿及人類所關注的熱點，因此，本節(jié)課對學生而言既有趣味性，又有挑戰(zhàn)性。 （二）教學目標(1)知識與技能目標：1.通過全球氣候的長期演變圖，學生了解全球氣候處在波動變化之中。2.通過資料認識全球氣候一直處于變化之中并呈現(xiàn)一定變化周期，了解全球氣候變化對地理環(huán)境及人類活動的影響，能夠提出一些氣候變化的適應對策。
