三角形內(nèi)角和定理教案教學設計
活動內(nèi)容：① 已知，如圖，在三角形ABC中，AD平分外角∠EAC，∠B=∠C．求證：AD∥BC分析：要證明AD∥BC,只需證明“同位角相等”,即需證明∠DAE=∠B.證明：∵∠EAC=∠B+∠C（三角形的一個外角等于和它不相鄰的兩個內(nèi)角的和）∠B=∠C（已知）∴∠B=∠EAC（等式的性質(zhì)）∵AD平分∠EAC（已知）∴∠DAE=∠EAC（角平分線的定義）∴∠DAE=∠B（等量代換）∴AD∥BC（同位角相等，兩直線平行）想一想，還有沒有其他的證明方法呢？這個題還可以用“內(nèi)錯角相等，兩直線平行”來證.

Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

從課程內(nèi)容來看，本節(jié)課屬于“圖形與幾何”中“圖形的性質(zhì)”部分。依據(jù)課標的要求，我從以下四個方面設定了課程目標，分別是：1。知識技能：（1）掌握判定直角三角形全等的“斜邊、直角邊”定理。（2）已知一直角邊和斜邊，能用尺規(guī)作出直角三角形。2。數(shù)學思考：（1）經(jīng)歷探索、猜想、證明的過程，進一步體會證明的必要性，發(fā)展推理能力和有條理的表達能力。（2）在探究過程中，滲透由特殊到一般的數(shù)學思想方法。3。問題解決：能利用直角三角形的全等解決有關問題。4。情感態(tài)度：通過學習，讓學生感受數(shù)學證明的嚴謹性，發(fā)展勇于質(zhì)疑、嚴謹求實的科學態(tài)度。
人教版高中地理選修3第五章第一節(jié)設計旅游活動教案
點撥：旅游地旅游資源的特色不同，可以安排的旅游活動是不一樣的，直接影響對旅游者的吸引力。因此，出游前首先就需要收集旅游地旅游資源的類型、主要游覽景區(qū)、景點的特色等情況。旅游地的時空可達性直接關系到旅游者從出發(fā)地到旅游地，然后再返回出發(fā)地的費用和時間。一般來說，居住地與旅游地之間的空間距離過大，會使旅行的時間過長、旅行費用過高，經(jīng)濟距離增加，相應地降低了旅游者的出游能力。而居住地與旅游地相距遙遠，也意味著兩地之間巨大的環(huán)境差異，這會增加對游客的吸引力。旅游服務設施和條件，如旅游交通方式及工具、旅游住宿條件、旅游餐飲的種類和標準、導游服務、旅行費用等信息也都在一定程度上影響著游客的選擇。圖5．3西藏布達拉宮和圖5．4云南香格里拉兩幅圖片顯示了西藏布達拉宮、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觀光旅游，成為近年來國內(nèi)旅游的熱點。
