【摘要】：我的這篇論文主要致力于研究幾何畫板這一繪圖工具如何來促進(jìn)初中數(shù)學(xué)中的平面幾何部分知識的教學(xué),在研究過程中,我主要是通過自己的實際教學(xué)過程中對幾何畫板的使用來研究說明。在本文中我以人民教育出版社出版的數(shù)學(xué)教材為依托,從學(xué)生剛開始學(xué)習(xí)平面幾何部分知識開始,就利用幾何畫板這一繪圖工具來輔助平面幾何知識的教學(xué)。在本文中我主要說明了自己在平時的教學(xué)過程中是如何利用幾何畫板來輔助我的教學(xué),主要包括了幾何圖形,直線、射線與線段,角的比較與運算,余角和補角,相交線和平行線,對頂角同位角、內(nèi)錯角、同旁內(nèi)角,平行線,平移,三角形,軸對稱,平行四邊形以及圓。在講解以上這些平面幾何的知識時,我基本上都是用幾何畫板這一繪圖軟件在課堂中給學(xué)生演示或者讓學(xué)自己用多媒體教學(xué)設(shè)備進(jìn)行操作來學(xué)習(xí)這些內(nèi)容。通過幾年的不斷努力,我自己的教學(xué)水平有了質(zhì)的飛躍,在教學(xué)的過程中不斷使自己的課堂變得更加的有趣了,而且學(xué)生在我的課堂中也收貨的成功與喜悅。學(xué)生在我課堂中的收貨是以前的傳統(tǒng)教學(xué)方式無能如何也做不到的,傳統(tǒng)的教學(xué)方式重點在于老師上課的講授,把所有的知識強硬的塞給學(xué)生,學(xué)生在課堂 .中收貨不了快樂。同時傳統(tǒng)教學(xué)方式也對學(xué)生的思維發(fā)展有一定的局限性。因此用幾何畫板來輔助初中平面幾何知識的教學(xué)已經(jīng)是大勢所趨,是21世紀(jì)課改背景之下一個所有老師都必須走的教學(xué)之路。因此本文的研究顯得尤為重要,它不斷為我以后的教學(xué)研究指明了方向,同時也可以為其他一線的老師的教學(xué)作為參考,使他們在利用幾何畫板來進(jìn)行教學(xué)時,可以少走一些彎路。幾何畫板進(jìn)入課堂來輔助老師對平面幾何部分知識的教學(xué),對老師的要求變得更高,老師不斷要具備一定的知識能力,還需要老師具備一定的計算機使用能力。因此,本文把所有需要用幾何畫板來輔助教學(xué)的平面幾何知識用最簡單的語言來產(chǎn)生,其他老師可以借鑒來輔助自己的教學(xué)。
[Abstract]:My thesis is devoted to studying how the drawing tool of geometric Sketchpad can promote the teaching of plane geometry in junior high school mathematics.I mainly through their actual teaching process of the use of geometric Sketchpad to study the explanation.In this paper, based on the mathematics textbook published by the people's Education Publishing House, I use the drawing tool of geometric Sketchpad to assist in the teaching of plane Geometry from the beginning of the students' learning some knowledge of plane geometry.In this paper, I mainly explain how I use geometric drawing board to assist my teaching in the normal teaching process, mainly including geometric figure, straight line, ray and line segment, angle comparison and operation, residual angle and complement angle.Intersecting lines and parallel lines, equal vertex angles, internal staggered angles, inner angles of the same side, parallel lines, translation, triangles, axisymmetric, parallelograms, and circles.In explaining the above plane geometry, I basically use the drawing software geometric Sketchpad to show the students in class or to learn how to use multimedia teaching equipment to learn these things.Through several years of continuous efforts, my own teaching level has made a qualitative leap, in the process of teaching to make their classroom more interesting, and the students in my class also received the success and joy.The students receive goods in my class is the previous traditional teaching method how incompetent can not do, the traditional teaching method is focused on the teacher teaching, all the knowledge hard to students, students in the classroom.I can't be happy to receive the goods in the middle.At the same time, the traditional teaching method also has certain limitation to the student's thought development.Therefore, it is the trend of the times to use geometric drawing board to assist the teaching of plane geometry knowledge in junior high school. It is a teaching way that all teachers must take under the background of curriculum reform in the 21st century.Therefore, the research in this paper is especially important, it has pointed out the direction for my later teaching research, and it can also be used as a reference for the teaching of other front-line teachers, so that they can make use of the geometry drawing board to carry on the teaching.You can take less detours.Geometry drawing board comes into the classroom to assist the teacher to teach the part of plane geometry knowledge, the teacher's request becomes higher, the teacher must constantly have certain knowledge ability, also needs the teacher to have the certain computer use ability.Therefore, all the knowledge of plane geometry which needs to be assisted by geometric drawing board is produced in the simplest language, and other teachers can learn from it to assist their own teaching.
