Adnormal Phenomenon between Position in Class and Position in Form

heidikl

I noticed a very adnormal phenomenon of Position in Class vs Position in Form for my son's form.  In my son's class, the #3 in class is the #3X (middle part of the 30) in the form. The #7 in class is not even in the Top50 in the form. For my son, his rank in the class is the same as last year but in form is also dropped. Then, I heard from other class, the #8 in class is #2X (very early part of the 20) in the form (for her case, her rank in class is improved by 1, the rank in form is significantly improved. But of course, it may be due to herself hardworking).

I didn't study Statistics but I was 6Sigma black belt before. If we do a hypothesis to test if the 2 classes  are the same, I think there is high confidence that the 2 classes are not the same.
So, I have a question if the students were randomly assigned in different classes. I assume it is. If so, why we come out this situation??

- If the teachers of my son's class didn't teach so well relatively so that their academic result dropped relative to other classes? (Personally I don't believe so and I don't want so.)
- If there is big variation in the marking scheme?? (seems this could be the reason)

I hope the school can study this and at least give our parents some explanation on that and if there is some area to be improved. I understand that we should not pay too much attention in the marks and the rank (my son himself doesn't care about that), but at least as a parent, I want the kid to be fairly assessed and we can better understand his progress.

I wonder if I should reflect this to the school? Any suggestion??

Hi Heidikl,

I'm not sure about the marking scheme of the lower grade, but for p5, I think they have tried to be fair in marking. For instance, according to my girl, all the Chinese composition exam papers were marked by the same teacher. Subjectivity may sometimes plays a role in some papers, such as VA and oral testing. But up to this moment, I personally think TSL teachers are quite fair.  

If you have doubt, I think you may feel free to send an email to your son's class teacher to learn more. I think the school may also find something odd about the ranking and they have re-calculated the scores. My girl's form ranking was slightly changed after adjustment.

heidikl,

As far as I know, the allocation of pupils to classes is at random.
Therefore, it could be possible that certain top pupils are allocated to class X at random so a similar position in class X might rank higher in grade than other pupils in class Y who rank at similar positions in class but not so high in grade.

同意 ahchoi 所講, 如果有疑問, 應該 send email 或約見老師求個明白.

I agree Ah choi.  My daughter also said their Chinese exam papers were marked by the same teacher.  However, I found that some class teachers inform the TOBs and Chinese dictations quite late if compare with other classes.  I think it would be more fair if the subject teachers in the same form can tell the students TOBs or dictations at the same day.  我估tobs/ dictations成績都有些少影響名次. 早通知的班可能多時間準備成績好d, 得果兩三日時間準備的班, 如果果幾日多野做, 又會平均來說做得冇咁好.  我睇法不一定正確, 不認同的希望唔好介意!

呀女佢嗰班嘅TOBS同中文默書通常都會有星期六同星期日嘅時間比佢地溫書, 好似呢兩日嘅TOBS同中默都係上個禮拜中就已經知道, 我都覺得OK嘅~ 不過係呀女懶唔溫, 唔到時候都唔攞本書出嚟, 真激死.:-x

以前呀媽用衣架當騰條, 打到發發聲架.

我曾經太過激氣, 忍唔著眼淚都出埋嚟, 點知呀女一見到我咁嘅樣, 就當堂乜脾氣都收哂, 仲安慰番轉頭同講哂對唔著.  但係我又唔想用呢啲方法lor~  我覺得而家教細路真係一門好高深嘅學問.  (不過可能其他家長啲小朋友乖啲, 冇我個咁激氣)

你地做呀媽激心嗰時都可以喊下, 我地做老豆就真係谷到爆渠, 鬧佢果時佢就入房, 吹佢唔脹! 打佢又驚佢大義滅親..........不過有時過咗一陣都會出o黎 say sorry, 個心當堂軟哂, 死未
