輾轉拿到了今屆會考數學和附加數學科的試題，看完後得感想如下：
數學科卷一
- 圓形的長題目，近年成了乙部的大熱；誰知這條「必考」題今年竟不翼而飛！相信教不少人跌破眼鏡 (包括栗子妹在內)。
- 不知是否知道考生怕做證明的題目，竟然在甲部(2) 出了一題，我看來年應該會照辦煮碗。
- 甲部(1) 竟然有一題考捨入？！不是賣大包賣得那麼離譜吧？
數學科卷二
- 嘿，都說「形心」(centroid)、「外心」(circumcentre)、「內心」(incentre)和「垂心」(orthocentre)是必考的定義，果然今年又出了兩題。
- 圖像 (graph) 在乙部出了三題，比我想像中的多，要提阿仔阿女溫習。
- 第28題我好像在中一的補充練習中見過？！
- 題目不算深，不過如果定義/概念不清晰，便會失很多分。
附加數學
- 竟然不考general solution！阿仔知道後不知多失望，還問我之前苦讀為何~~~
- 二項式 (binomial theorem) 的一題有意思，不過要如何表達展開式中沒有常數項，對我來說有點難度。
- 點解我最後一題第二部分計到 AB = (1/2)h 呢？有誰可以教教我？
總的來說，今年的試題頗容易，要拿優看來不易。

今天最後一科，謝天謝地，學子們考完了

回覆刪除What is 圓形的長題目 ?
I don't recognize any of those definitions in 數學科卷二
What's "general solution"?
I remember the binomial distribution from U, but have forgotten the "theorem".
And, how did you get your hands on the paper so soon. They don't publish past papers until a year or so after the fact, no?
[版主回覆05/13/2009 08:10:00]It's alright, Teacher. You don't teach Maths, do you?
There's a topic about circles in G Maths. It talks about the properties of circles like angles in the same segment, tangents, etc.
Those four defintions are newly added. I think 出卷員 are obsessed with them because they appear so frequent!
For general solution, I mean those for sine, cosine and tangent, such as 180n + a.
As for binomial theorem, we teach students the concept of factorial and binomial expansion in A Maths.
Regarding the paper, can't you guess?
I guess I'd better not teach math. I did when I was working as an assistant at an ESF school, but I didn't see anything like what you descrtibed. I haven't done it in several years.

No, I have no clues on how you got your hands on the paper so soon, unless you were an invigilator (what a word!) which receives a courtesy copy of the exam paper you invigilated. However, I'll venture a guess in private.
