【摘要】：數(shù)學(xué)是具有較強(qiáng)邏輯性的基礎(chǔ)學(xué)科,知識(shí)抽象,學(xué)生需要較高的學(xué)習(xí)能力;教師需要有扎實(shí)的專業(yè)知識(shí)背景、較強(qiáng)的邏輯思維和合理的推導(dǎo)能力;學(xué)校需要必要的輔助教學(xué)設(shè)備和輔助教學(xué)工具。在新課程改革背景下,產(chǎn)生了許多輔助數(shù)學(xué)教學(xué)軟件,幾何畫板就是其中一種,它簡(jiǎn)單易學(xué),功能強(qiáng)大,在國(guó)內(nèi)中學(xué)數(shù)學(xué)教學(xué)中被廣泛普及。二次函數(shù)是歷年中考的重點(diǎn)和難點(diǎn),它具有抽象性、變化性和綜合性,需要學(xué)生具有一定的抽象思維能力和分析能力。而對(duì)于教師教育理念相對(duì)落后、教學(xué)條件差、硬件設(shè)施起步晚而且設(shè)備落后、班級(jí)學(xué)生基數(shù)大、學(xué)生學(xué)習(xí)能力普遍偏低的農(nóng)村初中而言,學(xué)生要學(xué)會(huì)用二次函數(shù)相關(guān)知識(shí)解決實(shí)際問題,難度頗大。由于幾何畫板簡(jiǎn)單易學(xué),對(duì)數(shù)學(xué)教師的技能要求不高,不需要過硬的硬件設(shè)施,符合農(nóng)村教學(xué)條件。本文對(duì)幾何畫板輔助農(nóng)村初中二次函數(shù)教學(xué)進(jìn)行實(shí)驗(yàn),對(duì)實(shí)驗(yàn)效果和問卷調(diào)查進(jìn)行統(tǒng)計(jì)分析、對(duì)教學(xué)效果進(jìn)行總結(jié),得到結(jié)論:使用幾何畫版能夠普遍提高學(xué)生的學(xué)習(xí)興趣、能夠提高學(xué)生學(xué)習(xí)二次函數(shù)的效果,尤其對(duì)中等成績(jī)和低分段成績(jī)的學(xué)生的輔助效果尤為明顯,而農(nóng)村初中學(xué)生的數(shù)學(xué)學(xué)習(xí)水平在中等成績(jī)和低分段成績(jī)的居多,所以幾何畫板在農(nóng)村初中數(shù)學(xué)教學(xué)中的應(yīng)用對(duì)提高農(nóng)村初中學(xué)生的學(xué)習(xí)興趣和總體數(shù)學(xué)成績(jī)能夠起到較為關(guān)鍵的作用。
[Abstract]:Mathematics is a basic subject with strong logic, knowledge is abstract, students need higher learning ability, teachers need solid professional knowledge background, strong logical thinking and reasonable deduction ability. The school needs the necessary auxiliary teaching equipment and the auxiliary teaching tool. Under the background of the new curriculum reform, there are many auxiliary mathematics teaching software, one of which is geometric Sketchpad, which is simple and easy to learn and has powerful function, which has been widely used in mathematics teaching in middle schools in China. Quadric function is the key and difficult point of the middle school examination over the years. It is abstract, changeable and comprehensive, which requires students to have a certain ability of abstract thinking and analysis. But for the rural junior middle school, the teacher education concept is relatively backward, the teaching condition is poor, the hardware facilities start late and the equipment is backward, the class student base is large, the student learning ability is generally low, It is very difficult for students to learn to solve practical problems with knowledge of quadratic function. Because the geometry drawing board is simple and easy to learn, the skill requirement of mathematics teachers is not high, and the excellent hardware facilities are not needed, which accords with the condition of rural teaching. This article carries on the experiment to the geometry drawing board to assist the rural junior middle school quadratic function teaching, carries on the statistical analysis to the experiment effect and the questionnaire survey, carries on the summary to the teaching effect, obtains the conclusion: the use of the geometry drawing version can generally enhance the student's study interest, It can improve the effect of learning quadratic function, especially for the students with middle grade and low segmentation, but the rural junior middle school students' mathematics learning level is mostly in the middle grade and low segmentation. So the application of geometric drawing board in mathematics teaching in rural junior high school can play a more important role in improving the students' interest in learning and overall mathematics achievement.
