no problem 毫無(wú)問(wèn)題; 考試家族; 沒(méi)問(wèn)題; 無(wú)問(wèn)題
problem n. 1.問(wèn)題,課題;疑難問(wèn)題;令人困惑的情況。 2.【數(shù)、物】習(xí)題;作圖題。 3.(象棋的)布局問(wèn)題。 the problem of unemployment 失業(yè)問(wèn)題。 His whole conduct is a problem to me. 他的一切行為我都不理解。 adj. 1.成問(wèn)題的;難處理的。 2.關(guān)于社會(huì)問(wèn)題的。 a problem child 【心理學(xué)】問(wèn)題兒童;難管教的孩子。 a problem novel [play] (反映社會(huì)問(wèn)題等的)問(wèn)題小說(shuō)[戲劇]。 sleep on [upon, over] a problem 把問(wèn)題留到第二天解決。
The result of problem - posing showed the students had higher performance on one - step than multi - step word problems . 3 后設(shè)認(rèn)知能力愈高的學(xué)生,其在擬題表現(xiàn)上也愈好。
The students who got higher score in meta - cognition ability had higher performance in problem - posing . 4 以整體試題而言,依次為量數(shù)同構(gòu)型、多重比例型、比較型、叉積型。
As we knew , problem was the motive force of invention . and problem - posing was the generative aspect of mathematical thinking 創(chuàng)造始于問(wèn)題,提出問(wèn)題反映了學(xué)生數(shù)學(xué)認(rèn)知的產(chǎn)生式方面的特征( cai , 1998 ) 。
This dissertation consists of the following five sections : the first section is the forward , which includes problem - posing , the main thoughts and research methods 本文包括以下五部分:第一部分:引言,包括問(wèn)題的提出和論文的主體與研究方法兩部分。
A number of researchers had conducted investigations to compare the performance of students " problem - posing and problem - solving . the findings of theses studies ( e . g 有研究顯示( cai , 1998 ;聶必凱,汪秉彝, 2000 ) ,我們的學(xué)生在提出問(wèn)題方面的能力也比較薄弱。
Cai , 1998 ; bikai nie , & bingying wang , 2000 ) provided evidence that , while our students outperformed on problem - solving tasks , the result was not the same on problem - posing tasks . because most students learned mathematics and developed increased mathematical capacities only when they participate in instruction focused on rich and worthwhile mathematical activity . however , in the circles of mathematics education , there was a universal sense , that is : our mathematical education loses contact with reality ; students solve problems not related to real life ; the mathematical activity students conducted mostly focused on memorization and mechanical use of procedures rather than the use of mathematical knowledge and tools to explore patterns , frame and solve problem , etc . 課堂是學(xué)生學(xué)習(xí)數(shù)學(xué)、發(fā)展數(shù)學(xué)認(rèn)知的主陣地,我國(guó)學(xué)生的數(shù)學(xué)認(rèn)知在上述方面表現(xiàn)出來(lái)的差異可以從數(shù)學(xué)課程與教學(xué)中尋找原因: “中國(guó)數(shù)學(xué)教育脫離實(shí)際” (張奠宙, 1994 ) ; “在強(qiáng)調(diào)素質(zhì)教育的今天,絕大多數(shù)課堂教學(xué)仍然是傳授知識(shí)加技能訓(xùn)練的傳統(tǒng)教學(xué)模式” , “學(xué)生的數(shù)學(xué)學(xué)習(xí)仍然是一種‘復(fù)制型’的‘消極’學(xué)習(xí)” , “學(xué)生幾乎沒(méi)有獨(dú)立思考、探索發(fā)現(xiàn)的機(jī)會(huì)” (季素月, 1996 ) ;我國(guó)數(shù)學(xué)課程在“探究”和“背景”上“較薄弱” ,在“運(yùn)算”和“推理”等方面“要求過(guò)高” (鮑建生,博士學(xué)位論文, 2002 ) 。
In order to probe the effects of spbi on students " mathematical cognition , this study focused on two instruction experiment ( part iii ) , one was . called unit - theme - situation experiment which created problem situation according to a unit theme ; the other one was called mini - situation experiment which created problem situation according to individual class . the following hypotheses were examined : 1 . students receiving spbi will perform significantly better than students receiving instruction traditionally on tasks assessing problem - posing 為了驗(yàn)證上述假設(shè),檢驗(yàn)spbi實(shí)驗(yàn)的效果,我們開(kāi)發(fā)了一種評(píng)估工具,稱為認(rèn)知評(píng)估工具( cai ) ,并針對(duì)不同的實(shí)驗(yàn)內(nèi)容分別設(shè)計(jì)了兩個(gè)作業(yè): “作業(yè)一( task ) ”用于檢查“單元情境問(wèn)題教學(xué)”的效果, “作業(yè)二( task ) ”用于檢查“微情境問(wèn)題教學(xué)”的效果。
