北師大版初中數(shù)學(xué)八年級下冊多邊形的內(nèi)角和與外角和說課稿2篇
a.第127頁隨堂練習(xí)1第（1）題。b.一個多邊形的邊都相等，這是一個正多邊形嗎?c.一個多邊形的內(nèi)角都相等，這是一個正多邊形嗎？d.所以，一個相等，也都相等的多邊形才是。（此檢測主要是讓學(xué)說出多邊形和正多邊形的定義，因為是在三角形、四邊形的基礎(chǔ)上，定義是一致的，所以不深究。在教材的處理上，把正多邊形放在了前面，兩個較為簡單的概念放在一起，便于學(xué)生理解和掌握。）2.各組展示四邊形的內(nèi)角和的計算方法。3.各組展示五邊形的內(nèi)角和的計算方法。（由各組派代表上臺板演，其它組補充，真正讓學(xué)生動起來）4.各組選擇前面最優(yōu)的方法，口述六邊形、七邊形的內(nèi)角和的算法。（以此上，學(xué)生可以利用對比的方法，選擇作出過三角形的一個頂點的對角線的方法，讓學(xué)生探索發(fā)現(xiàn)規(guī)律。）5.據(jù)此，你們認(rèn)為n邊形的內(nèi)角和應(yīng)該怎樣計算。（注意n的條件）五、當(dāng)堂訓(xùn)練。

北師大版初中數(shù)學(xué)八年級下冊平行四邊形的性質(zhì)說課稿2篇
注意：平行四邊形中對邊是指無公共點的邊，對角是指不相鄰的角，鄰邊是指有公共端點的邊，鄰角是指有一條公共邊的兩個角．而三角形對邊是指一個角的對邊，對角是指一條邊的對角．（教學(xué)時要結(jié)合圖形，讓學(xué)生認(rèn)識清楚）設(shè)計意圖：通過觀察圖片和回顧以前的知識，使學(xué)生由感性認(rèn)識上升到理性認(rèn)識。通過描述平行四邊形的特點和定義，也培養(yǎng)了學(xué)生的語言表達(dá)能力。同時也滲透了一些由實際問題轉(zhuǎn)化為數(shù)學(xué)問題的“轉(zhuǎn)化”的數(shù)學(xué)思想。（三）、引導(dǎo)實驗探索新知【探究】平行四邊形是一種特殊的四邊形，它除具有四邊形的性質(zhì)和兩組對邊分別平行外，還有什么特殊的性質(zhì)呢？我們一起來探究一下．動手操作并思考：讓學(xué)生根據(jù)平行四邊形的定義畫一個一個平行四邊形，觀察這個四邊形，它除具有四邊形的性質(zhì)和兩組對邊分別平行外以，它的邊和角之間有什么關(guān)系？度量一下，是不是和你猜想的一致？

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

一、說教材 《一只窩囊的大老虎》是統(tǒng)編教材小學(xué)語文四年級上冊第六單元的第19課，這是一篇精讀課文。作者葉至善回憶他童年時候，在一次班級演出時上臺扮演老虎的故事。課文內(nèi)容淺顯，但耐人尋味。按照課文的寫作順序，可以歸納為四部分：期盼參加演出，排練扮演老虎，飾老虎沒成功，尋找失敗根源。在講述怎樣演老虎時，故事中演“哥哥”的小朋友一直認(rèn)為扮老虎要有“豁虎跳”，而老師為鼓勵“我”認(rèn)為不一定要“豁虎跳”，二者的矛盾貫穿始終。最終“我”在正式演出時演砸，于是“我”尋求原因。有意思的是作者沒有直接道出原因，而是以“我至今還不明白”結(jié)尾，給學(xué)生留下思考的空間。二、說教學(xué)目標(biāo)： 1.學(xué)習(xí)生字新詞。2.默讀課文，在不理解的地方作批注，和同學(xué)交流。

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑體部分在句中作表語。2. 句1、2、3中的that在從句中不作成分，只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

對初中英語教師說課技能的思考與建議
一、認(rèn)識說課的實質(zhì)說課是指教師以現(xiàn)代教育理念為指導(dǎo)，在精心備課的基礎(chǔ)上，面對同行或教學(xué)研究人員，采用口頭語言或相關(guān)輔助手段，闡述某學(xué)科課程或某具體課程的教學(xué)設(shè)計及其依據(jù)的教學(xué)研究過程（李崇愛,孟應(yīng)周,2011）。簡單而言，說課就是教師對“教什么”、“怎么教”、“為什么這么教”等問題進(jìn)行闡述。這樣做的目的，一方面可以展現(xiàn)一個教師的教育理論修養(yǎng)、教學(xué)組織能力和口頭表達(dá)能力，另一方面可以幫助教師優(yōu)化教學(xué)設(shè)計，反思教學(xué)行為，分享教學(xué)經(jīng)驗。
