人教A版高中數(shù)學必修二直線與平面垂直教學設計

  • 北師大初中九年級數(shù)學下冊直線和圓的位置關系及切線的性質教案

    北師大初中九年級數(shù)學下冊直線和圓的位置關系及切線的性質教案

    解析:(1)由切線的性質得AB⊥BF,因為CD⊥AB,所以CD∥BF,由平行線的性質得∠ADC=∠F,由圓周角定理的推論得∠ABC=∠ADC,于是證得∠ABC=∠F;(2)連接BD.由直徑所對的圓周角是直角得∠ADB=90°,因為∠ABF=90°,然后運用解直角三角形解答.(1)證明:∵BF為⊙O的切線,∴AB⊥BF.∵CD⊥AB,∴∠ABF=∠AHD=90°,∴CD∥BF.∴∠ADC=∠F.又∵∠ABC=∠ADC,∴∠ABC=∠F;(2)解:連接BD,∵AB為⊙O的直徑,∴∠ADB=90°,∴∠A+∠ABD=90°.由(1)可知∠ABF=90°,∴∠ABD+∠DBF=90°,∴∠A=∠DBF.又∵∠A=∠C,∴∠C=∠DBF.在Rt△DBF中,sin∠DBF=sinC=35,DF=6,∴BF=10,∴BD=8.在Rt△ABD中,sinA=sinC=35,BD=8,∴AB=403.∴⊙O的半徑為203.方法總結:運用切線的性質來進行計算或論證,常通過作輔助線連接圓心和切點,利用垂直構造直角三角形解決有關問題.

    (二)、操作--“空間與圖形”學習的基本途徑 皮亞杰曾說:“數(shù)學的抽象仍是屬于操作性質的,它的發(fā)生發(fā)展要經過連續(xù)不斷的階段。而其最初的來源又是十分具體的行動?!币蛐W生的年齡特點和認知規(guī)律(動作感知--建立表象--形成概念),決定小學生的數(shù)學學習離不開操作感知這一基本途徑。 本案例中,通過讓學生折一折體會長方形、正方形邊的特征;讓學生用幾個相同的長方形、三角形拼一拼,感受圖形從簡單到復雜的變化規(guī)律;最后一題讓學生自己畫一畫,看看需要幾個長方形等。教師積極創(chuàng)造條件,組織學生動手操作,以此來參與知識的形成過程,使他們在親身體驗和探索中認識和感悟圖形的特征,理解和掌握圖形拼組的規(guī)律所在,并發(fā)展學生的思維,提高實踐能力。如果只視學生為接受知識的容器,向學生灌輸知識,這節(jié)課幾分鐘就可以搞定,但是學生對長方形對邊相等、正方形四條邊相等,圖形拼組中的很多細節(jié)都會是干巴巴的,所學的知識必然是有“形”無“神”的死知識。

    The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical. It is worth noting that the two authors do not express their views on studying abroad from an individual point of view, but from a national or even global point of view. These two articles have the characteristics of both letters and argumentative essays1.Guide the students to read these two articles, and understand the author's point of view and argument ideas2.Help the students to summarize the structure and writing methods of argumentative writing, and guides students to correctly understand the advantages and disadvantages of studying abroad3.Cultivate students' ability to analyze problems objectively, comprehensively and deeply

    This section guides students to pay attention to the typical context of vocabulary use, helps students accumulate vocabulary around the key vocabulary of this unit, and uses the learned words and word chunks in different contexts to deeply understand their meaning and usage, so as to achieve the purpose of review and consolidation.The teaching design activities aim to guide students to pay attention to the typical context in which the target vocabulary is used, as well as the common vocabulary used in collocation, so that students can complete the sentence with correct words. In terms of vocabulary learning strategies, this unit focuses on cultivating students' ability to pay attention to collocation of words and to use word blocks to express meaning.For vocabulary learning, it is not enough just to know the meaning of a single word, but the most important thing is to master the common collocations of words, namely word blocks.Teachers should timely guide students to summarize common vocabulary collocation, such as verb and noun collocation, verb and preposition collocation, preposition and noun collocation, and so on.1. Guide students to understand and consolidate the meaning and usage of the vocabulary in the context, 2. Guide the students to use the unit topic vocabulary in a richer context3. Let the students sort out and accumulate the accumulated vocabulary, establishes the semantic connection between the vocabulary,4.
