人教版高中生物必修1降低化學反應活化能的酶說課稿
實驗是學習生物的手段和基礎，是培養(yǎng)學生分析問題、解決問題的能力及創(chuàng)造能力的載體。新課程倡導：強調過程，強調學生探索新知識的經歷和獲得新知的體驗，不能在讓教學脫離學生的內心感受，必須讓學生追求過程的體驗。并且每年高考都有對生物學實驗的考查，而且比例越來越重，而學生的失分比例大，主要在于他們沒有完整的生物實驗設計模式，考慮問題欠缺，本節(jié)安排在第二課時完整講述高中生物學實驗設計，是以學生在第一課時和前面探究實驗接觸的前提下，完整體驗生物實驗設計模式，為后面學習探究實驗打下基礎，也為培養(yǎng)學生分析問題、解決問題從一開始就打好基礎。五、說教學過程：第一課時聯(lián)系生活，導入新課，激發(fā)學生學習興趣→細胞代謝→問題探究，酶在代謝中的作用，掌握科學實驗方法→酶的本質，運用方法，自主歸納獲取新知→小結練習，突出重點易化難點
人教版高中政治必修4關于世界觀的學說說課稿（二）
一、教材分析1、本框題在教材中的地位。本框題教材所處的地位及聯(lián)系：《關于世界觀的學說》是人教版2004年12月第一版教材高二政治必修4第一單元第二框題，在這之前學生已經學習了生活處處有哲學的內容，了解了哲學與我們的生活息息相關，這為過度到本框題的學習起到了鋪墊的作用。本框題又是學生進入哲學的入門，因而它在生活與哲學中具有不容忽視的重要地位。學好本框題，為學生從總體上對哲學的理解，為以后學好哲學做了良好的鋪墊作用。本框題是進入哲學與生活不可缺少的部分，也學生的學習生活常常遇到的問題。2、教學目標：1. 知識目標：（1）哲學的含義；（2）哲學與世界觀的關系；（3）哲學與具體科學知識的關系。2. 能力目標：（1）通過對哲學與世界觀、方法論、具體知識三對關系的分析，培養(yǎng)辯證思維的能；（2）通過對身邊生活事例、哲理故事、哲學家觀點的體悟，培養(yǎng)分析問題的能力；
人教版高中政治必修4哲學的基本問題說課稿（二）
②關于哲學的第二個問題是——思維和存在有沒有同一性解釋同一性——就是說意識（思維）能否正確認識物質（存在）的問題。（讓學生表達他們自己的意見）總結得出三種看法——認為意識（思維）可以正確認識物質（存在）的，屬于可知論者；凡是認為意識（思維）不能正確認識物質（存在），屬于不可知論者。當然也有些同學是兩者觀點都有，這種同學我們把他稱為不徹底的不可知論者。2、為什么思維和存在的關系問題是哲學的基本問題（1）它是人們在生活和實踐活動中首先遇到和無法回避的基本問題（舉例說明問題，吃飯的時候吃什么菜，學習計劃與學習的實際等等）結合教材P10探究進行講解舉例：11月31日請全班同學吃雪糕，吃完后再去肯德基大吃一頓，之后再到卡拉OK唱通宵——不切實際，因為11月并沒有31日。（2）它是一切哲學都不能回避、必須回答的問題（不同的回答，直接決定著哲學的不同發(fā)展方向。）
