英國小學將推廣“中式教育”?
英國教育部上周宣布，根據改革計劃，將在全英8000所小學推廣采用中國傳統數學教學方法。這一數字占到英國小學總數的一半。
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數學教學方法，以防止英國小學生(的數學成績)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學教育和英式數學教育的特點。
中式數學教育(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)。
近兩年引爆互聯網的奇葩數學題：
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
