幾深幾淺都好，最緊要能將所學的化成常識，且從中體會其思考方法。以我為例，中學所學的，都已忘記得一幹二凈，但小朋友如有疑難，我看一看書，總能給他滿意之解釋。小朋友常讚我講得比他老師好。這點我同意，母語教学嘛！

hi,

若然無記錯以前中学時期先学嘅修辭手法(明喻、暗喻、排比...)已在小三下学期的課程出現,而小五上学期已要用暗喻作句子,真係佢識我我唔識佢,宜家嘅小学課程的已而確好深,小ｄ努力都好難追上!

其實學既學生
同唔學既學生比
係咪叻左？

1.
曾聽一位名校中學老師說, 會考攞6A以上的理科尖子大都是以前玩奧數的.
2.
但我想這也不能證明有因果關係, 因為肯在奧數下苦功的, 相信本身已是數學尖子.所以你的推想難以去證實.
3. 但無疑奧數很多內容都是中學數理科時會遇到的刁鑽難題, 在中學便易取好成績; 我猜想在奧數經常攞獎的那批學生, 由於學懂的範疇很廣很深, 其數學根基可能不下於沈詩鈞.

我見過丘成桐批評奧數，所以都擔心是否適合送小朋友去
不過佢都有話有其好處

“奧數即使得金獎，也只能證明考試的能力，不代表就有研究能力。數學是做研究，研究的根本是找問題。奧數只訓練別人的題 ...

丘教授所說的有點曲高和寡, 個人不太認同:
1. 所有做研究的都要學找問題, 不單是數學。
2. 要做好數學研究,懂設問題找答案, 也需要有優秀的數學理論根底和運算能力, 而奧數正好提供這些基本訓練(自學也可以)。
3. 不一定做數學研究的才是數學家。在應用數學領域裏,例如精算,財算,結構工程,電子工程, 天文,物理等等,[解決問題]也相當重要和常見, 也需要良好的數學解難和運算能力。

Dear Judy

I just came across your post by accident and let me offer some help.

雞兔合共有12頭，脚合共32隻。問雞、兔各有多少頭？

First we "cut" two feet from each rabbit. With 12 animals, we would then have 24 feet, i.e. 8 feet less than the original 32. These must have come from the rabbits. They should have come from 4 rabbits. If we have 4 rabbits, originally we have 16 rabbit feet. In other words, (32-16=) 16 feet came from chickens, i.e. 8 chickens.

The maths problem is actually quite simple without resorting to simultaneous equations. But once you have learned algebra, few people are willing to go back to basic arithmetics.

Dear Edward,

老朋友又再見面，真開心！

最早見此雞兔問題，是我侄兒小五時問的(他今年已中六)，其時全家都唔識，要我老爸出手。兩年後，我第二個侄兒又考奧數，我們又忘記了其計法，又要老爸出手。到阿大考奧數，我己將他過俾我老爸教。

中國人很聰明，但用錯咗，所以發明不了代數。我同意丘成桐之看法。

Wumun話佢個女小三已教此問題，看來奥數只會越來越深。我想一般小三學生根本無法計此數，只有將方法背下，對孩子之發展，真係唔知好定唔好？

作者: lwl2007 時間: 07-11-26 11:17 標題: Our Secondary School Syllabus is really easier as compare before

If you look at the HKCEE and HKALE examination 10 year ago, 1987 HKALE, the syllabus include complex number, integration definite and indefinite, partial fraction, trigonometric analysis, limit and continuity and sequences. However, nowaday, secondary school students need not to study complex no., when they promote to year 1 of BEng in Electrical and Electronic Engg., some of them get into trouble as they don't know much about complex phasor and finally they are quite weak in circuit analysis and electrical machines. For higher level Digital Signal Processing involving S-domain and Z-domain transformation, some of them cannot handle it. Therefore nowadays the Engineering Math. and Course Syllabus have been re-adjusted in order to suit our University student. What I am saying is truth as you can compare the Syllabus of Engineering Math. in most of the local University with that of several years before. The insufficent training in Secondary education in Hong Kong causes some problem to tertary education.

The primary school tends to be too difficult as it may be quite easy to teach so call difficult topics to kids in advance but these topics are relative easy to adult and therefore most of the primary school teacher can handle it. However, look at out secondary school education, the Government just know cutting down some difficult syllabus topics. Have you heard about secondary school teacher try to teach sec 2 math, in sec. 1 and University Year 1 topics in form 7. No ! I doubt how many school can handle these approach, is there any secondary school can use the same approach as St. Franics Primary that teach every topics in advance and therefore pushing their students perform better ! The materials in secondary is become difficult as most of the parent may not understand whether it is too much and appropriate to our child. Most of the parent cannot supervise closely on what our child have learnt in secondary school as these materials are quite difficult and professional. So we rely on school and tutor. Primary school just emphasize the so call gift education and teach everythings in advance but do you think that the educator can using the same approach in secondary school education !

Mathematics is a very serious subject which include Hypothesis, Theorem and derivation if you actually look at it in more detail but if we just want to train our kids to think and solve problem from different point of view, it is no harm to study Olympas Math. In fact, from my point of view, it extract some foundation materials from advance subject such as Discrete Mathematics, Probability Combination and Permutation, Linear Systems and Sequence and Math. Induction from higher level study. It may be helpful to let our kids to be expose to these topics in just foundation level before they are promote to secondary school.

What prof. Yau said is true only for those PhD students who want to be a researcher in University. For kids we just want to train them to think and solve problem from different point of view. Who know whether they will become Mathematician or Professor getting Nobel Prize (like Professor Yau) in the future ! We just want our kids to re-inforce their math. training and calculation !

Dear parent,

Education reform actually intend to cut the depth of each subject and boarden the width of learning. But the outcome is most parent due to whatever reason (middle class all concentrated in stock, property investment, lower class struggle for live) and wholly rely on the school to teach their kids. For Pri. school, you can still pushing them as such. For Sec. school, all are independent and either the kids ignore your advise or just concentrated on those exam related areas, thus upsetting the whole intention and producing those high mark low Q's. If you had chance to meet those sec. and tri. graduate, you should prepare a sink to hold your blood.

Sometimes I find it difficult to give guidance to my son for his learning. Firstly, I have not kept updating my science knowledge for over ten years. When my son ask me some questions about Integrated Science, I forget everything and I cannot answer his questions ! Even for the Math. course, I have not studied Math. for many years, sometimes, I cannot solve his problem and give him the correct answer ! For form 1 to form 3, I can handle some of the subjects, but when he promote to Form 5, I think that he must relay on himself or I try to find a tutor for him !

我認為就算唔識，都可以教到小朋友。有沒有試過小朋友問問題，你只是依依哦哦地應着，過一會，他會說多謝你，但你根本未回答過問題。

有一次小朋友考樂理，問我何謂大三元音和小三元音。我係音樂盲，根本無從回答。我於是向他健議，不如打開鋼琴彈一下。我剛說完，小朋友已明白過來，仲猛咁讚我醒。

我反對補習，補習剝奪了孩子思考之機會，除非教師不教。侄兒去年考中五，他說很討厭生物課，因教師連讀課本也讀得有氣無力亂七八糟。家人於是健議他去補習，市場經濟加上母語教育，侄兒話個教師每堂都象做talk show，進步神速，會考A埋。

Dear lwl2007,

May be I can share experience on teaching my kid. At one time I was asked by my son on PTH and I know nothing on this lang., I can just refer him to the relevant source and let him find the answer by himself. Another time is he ask me about the Math., I know how to approach it but I keep on asking him to find what their textbook's approach. What I am saying is you should let them solve their problem rather than giving the answer directly.

For the tutor part, if your kid already used to solve the problem by themself, there is no need for it. Tutoring class will give you the best and efficient answer but never telll you why should it be like that. Of course you can 'memorize' it and score very high marks (don't forget the exam. auth. now are thinking of what the student 'probably' know and set the questions toward it), should this treat as coorperation between the tutor class and the exam. auth.? If you ask me did I hire private tutor before, the answer is yes. The purpose of it is not teaching my kids to score high mark nor to teach them the homework, only one reason is to let them strengthen some very specific area such as english, PTH oral presentation, panio etc.

It's very hard for parent to ignore the exam. marks (local one) under the current education system but think about if he kids are just concentrating on the exam. related area(s), will they still has the interest/time for exploring what should they know for future survival. One very silly example is I remember the interview case on the past F.7 top graduate that most of them will select HKUST coperate finance because of high salary upon graduation. Should you feel comfortable on their act? If their answer is they got interest on the areas may be a bit better (I strongly against kids/teenager to touch on investment), the perfect one may be they want to study the behaviour of economic system in the current macro environment. What I am saying is HK student are so short sighted and just want immediate return, may be it is their parent's intention.

Sorry for so long speech!

I am not challenging their IQ but their attitude, when they find some difficulties, some of them just waiting for someone to help them ! Some of them are irresponsible, just leaving the problem to other and ressign within a short-time !

Dear uncleedward,

Apparently, your method seems easy. But, it is actually lack of giving a proper mathematical treatment or insight into mathematical problems. In other words, dealing with the problems of chickens and rabbits is okay. If students are asked to solve problems with tricycles, bicycles or lorries, big trucks, your "chickens and rabbits" method can't help. Conversely, students can get learn anything from the problem. I just want to say "Learning mathematics is not simply to calculate the correct answer in short time, but to learn, understand and appreciate the process of getting the answers."

Dear uncleedward,
It is not so much about equations, but the way of solving problems. You used a particular case trying to ignore the importance of equations. Of course, you can solve the problem and get the answer, but it doesn't imply students can tackle similar problems in the situation with complicated combinations.

In short, your suggested method can be considered to be clever, but not wise.

Dear uncleedward,

You are exactly correct. The method you suggested is only suitable for P5 and P6. Unfortunaetly, students have to learn another way in S1 and up. Thus, you want your kids to prepare for P5 and P6 only, or a general approach for the future. Your focus is still limited to Primary study.

Hi, uncleedward,

Your solution of 雞兔問題 is quite interesting. Can you provide the method of other question.
i.e. 雞兔同籠、工程問題、水管問題、流程問題、父子年歲問題、兩數和差問題 ...

In fact, my solution is pretty standard. It was only that I used "cutting off the rabbits' feet" to make it easier for kids to remember.

For 兩數和差，we have the following formula from most text books:

(兩數和 + 兩數差) / 2 = 大數
(兩數和 - 兩數差) / 2 = 小數

If you're interested in non-algebraic solutions to other problems, I suggest you go to the library to pick up a book (for example one of those from 九章出版社) to look it up.

Non-algebraic methods tend to more tedious than using equations but they tend to be more interesting as well.

It is always nice for a kid to master more advanced mathematical tools than those currently taught at school, but in no way this should be the requirement for all the students.

For example, in Mathematics at HKCE level, we are not supposed to use differentiation to find the minimum or maximum value of a quadratic function. The more tedious "completing the square" method is expected. Even in Additional Mathematics, to find the area of a triangle in coordinate geometry, one is not expected to use the more general, and much simpler "determinant" method learned in more advanced maths.
