摘要
    數(shù)學(xué)開(kāi)放題是20世紀(jì)70年代出現(xiàn)的一種新題型，目前不僅已成為數(shù)學(xué)教育領(lǐng)域聚焦的熱點(diǎn)，而且也已成為數(shù)學(xué)教育領(lǐng)域研究的亮點(diǎn)，被認(rèn)為是當(dāng)今最富有價(jià)值的題型之一。數(shù)學(xué)開(kāi)放題是指那些答案不唯一，可以從多方面、多角度、多層次進(jìn)行探索，給解題者在主觀上留有較大自由度和思維空間的數(shù)學(xué)問(wèn)題。數(shù)學(xué)教育的根本目的是培養(yǎng)學(xué)生的各種數(shù)學(xué)能力。在數(shù)學(xué)教育中,開(kāi)放型題具有重要的數(shù)學(xué)教育價(jià)值，對(duì)于激發(fā)學(xué)生學(xué)習(xí)的興趣, 訓(xùn)練學(xué)生數(shù)學(xué)建模的方法, 培養(yǎng)學(xué)生的發(fā)散思維能力等都具有重要的意義和作用。

Abstract
Mathematics opening topic is one kind of new topic which the 1970s appeared, not only at present has become mathematics educational fields focusing the hot spot, and has also become mathematics educational fields research the luminescent spot, was considered that is now one of richest value topics. Mathematics opening topic is refers to these answers not to be only, may from various, the multiple perspectives, multi-level carry on the exploration, subjectively leaves leeway the great degree-of-freedom and the thought space mathematics question for the problem solving. The mathematics education's primary purpose raises student's each mathematical skill. In mathematics education, the open-type topic has the important mathematics educational value, regarding stimulates the interest which the student studies, trains the student mathematics modelling the method, raises student's radiation power of thought and so on has the vital significance and the function.
Key  words: Mathematics open topic, explore, mathematical abilities, mathematics education value.
