今日剛考完的數學科,連數學老師都說難,看來真的不妙。
讀文科的學生說,卷一乙部只夠時間答一題半,栗當然不會責怪。話說若干年前,栗某個學生在乙部半題不答,最後竟拿了個D,可想而知,甲部的問題才是成敗的關鍵。
說回卷一乙部,今年除了三角形立體圖和概率+統計這兩條熱門題,還翻炒了圖形序列題,這分明是偏離了生活應用題這大趨勢,被將了一軍……
而最最意想不到的是,有一題竟然是關於圖像移位!不用看題目,都猜到沒多少人會選答──這個課題,誰會放在心上?
今屆會考真的有必要出得那麼難嗎?若有大批學生不及格升不了級,新學制那邊可沒有老師有時間支援耶……
與其說今屆是末代會考,倒不如說是末日會考,可能來得更為貼切。
I got the one on statistics but couldn't even understand the other three questions...

[版主回覆04/27/2010 19:46:00]Teacher: A fellow blogger also hinted that Section B was quite difficult for him. I'll definitely have a good look at the test paper tomorrow.
圖像移位 = transformation??
回覆刪除[版主回覆04/27/2010 19:47:00]Probably, Raymond. I'm not sure what the question is about though. Waiting for tomorrow ...
甚麼是 "圖形序列" ?? 可否舉例說明呢??
回覆刪除[版主回覆04/28/2010 07:22:00]對不起我譯得不,這是指Geometric sequence的圖形題,2000年至2003年的會考數學卷,每年都有一題。
哦!! 即係 Geometric Progression (G.P. )
回覆刪除The sequence a , a r , , . . . is called a geometric progression.
' a' is the first term and ' r ' is the common ratio of the geometric progression.
咁我明白啦 ....
[版主回覆04/28/2010 17:35:00]講開 GP,唔知點解宜家教科書全部用 GS 代替......
