英國教育部上周宣布,根據(jù)改革計劃,將在全英8000所小學推廣采用中國傳統(tǒng)數(shù)學教學方法。這一數(shù)字占到英國小學總數(shù)的一半。
我們來看看英國媒體的報道:
Half of primary schools will adopt the traditional Chinese method of maths teaching in a Government drive to stop British youngsters falling behind their Asian counterparts.
在政府推動下,全英將有一半的小學采用中國傳統(tǒng)數(shù)學教學方法,以防止英國小學生(的數(shù)學成績)落后于亞洲的小學生。
They will ditch ‘child-centred’ styles and instead return to repetition, drills and ‘chalk and talk’ whole-class learning.
這些小學將摒棄“因材施教”的教學方式,轉而采用重復、訓練以及“粉筆加口授”式的整班教學方式。
Teachers will be offered training, textbooks and advice on how to adopt the ‘Shanghai maths’ method.
英國小學教師將就如何實行“上海數(shù)學”教學法得到相關教材,接受培訓和意見指導。
英國小學生在數(shù)字計算能力國際排名(international league tables of numeracy)中被中國、新加坡和日本的孩子們遠遠甩在后面。批評人士認為,這都要歸罪于英國學校目前實行的以學生為中心的教學方式。
那么我們就來看看中式數(shù)學教育和英式數(shù)學教育的特點。
中式數(shù)學教育(Chinese method of maths teaching)
以課本為基礎的教學方式(teaching method backed up by textbooks),所有的學生通過不斷的運算和練習掌握基本的運算規(guī)則后才開始學習下一階段的內容。特點:重復性(repetition)、多次訓練(drills)、粉筆加口授(chalk and talk)、整班教學(whole-class learning)。
英式數(shù)學教育(British method of maths teaching)
以個體為基礎的教學方式(individual-based teaching),班里的學生根據(jù)不同水平分組,各組按照各自的水平學習不同難度的材料(classes are often divided into groups based on ability, with each group given work of varying difficulty)。特點:學生為中心(child-centered)、專注于把數(shù)學應用于真實場景(focusing on applying maths to real-life scenarios)、分組教學(group learning)。
近兩年引爆互聯(lián)網的奇葩數(shù)學題:
Hannah's sweets
There are n sweets in a bag.
6 of the sweets are orange.
The rest of the sweets are yellow.
Hannah takes at random a sweet from the bag.
She eats the sweet.
Hannah then takes at random a sweet from the bag.
She eats the sweet.
The probability that Hannah eats two orange sweets is 1/3
(a) Show that n^2 - n - 90 = 0
漢娜的糖
包里有n個糖。
其中有6個是橙色的。
其余的是黃色的。
漢娜隨機從包里拿了一個糖。
吃了。
漢娜又隨機從包里拿了一個糖。
吃了。
漢娜吃到兩個橙色糖的可能性為三分之一
求證:n^2 - n - 90 = 0
Solution:
Take the words from the question, and write it down as an equation - 6/n x 5/(n-1) = 1/3
Multiply the 6 by the 5 and the n by the n-1. That gives you: 30/(n^2 - n) = 1/3
Multiply the top-left by bottom-right and top-right by bottom-left
Subtract 90 from both sides, leading to your answer n^2 - n - 90 = 0
解:
將題目中的表述列成等式:6/n x 5/(n-1) = 1/3
左邊兩項相乘的結果為:30/(n^2 - n) = 1/3
等式兩邊的分子與分母分別相乘得出:n^2 - n =90
兩邊各減去90得出:n^2 - n - 90 = 0
Use the repeated addition strategy to solve 5X3
5X3=?
用重復加法來計算5X3
錯誤答案:5+5+5
正確答案:3+3+3+3+3
