阿富汗本科生對(duì)基礎(chǔ)群論概念的理解研究

發(fā)布時(shí)間:2021-07-10 21:51
  高中代數(shù)大多是基于代數(shù)運(yùn)算和方程求解。而大學(xué)代數(shù)則是基于集合論定義和形式證明。由于群論概念在本科代數(shù)中的抽象性和表征形式,這種向形式化數(shù)學(xué)的過(guò)渡是不容易的。群論概念的抽象表征對(duì)學(xué)生的理解力來(lái)說(shuō)是不小的挑戰(zhàn),而且影響他們是否能學(xué)好這門(mén)課程。本研究探討了阿富汗本科生對(duì)重要群論概念的理解、在學(xué)習(xí)群論基本概念時(shí)產(chǎn)生的錯(cuò)誤觀念和遇到的困難、以及產(chǎn)生這些錯(cuò)誤觀念和困難可能的來(lái)源或原因,相關(guān)的一些以前的概念,以及學(xué)生對(duì)于這些形式化構(gòu)建的概念的定義在觀念上存在的有力和不利的方面。本研究利用大衛(wèi)·塔勒(David Tall)的“數(shù)學(xué)的三個(gè)世界”理論和學(xué)生的問(wèn)題解決能力,作為測(cè)評(píng)學(xué)習(xí)者在解決基礎(chǔ)群論概念相關(guān)問(wèn)題的理解水平的一種方法。對(duì)112名學(xué)生以書(shū)面問(wèn)卷的形式收集的有關(guān)基礎(chǔ)群論概念相關(guān)問(wèn)題的數(shù)據(jù)分析表明學(xué)生對(duì)基礎(chǔ)群論概念的理解存在幾個(gè)突出問(wèn)題。本研究表明總體上隨著群論概念變得越復(fù)雜,阿富汗本科生對(duì)這些概念的理解變得越困難。本研究還表明阿富汗本科生在理解群論概念方面存在新的錯(cuò)誤觀念和許多困難。尤其是,本研究發(fā)現(xiàn)首要困難與群論中概念定義的符號(hào)表征有關(guān)。與具體形式化數(shù)學(xué)世界中概念的文字定義相比,學(xué)生更難理解數(shù)...
