2012 PSLE Discussions and Strategy

mn:

Sometimes the school homework is easy. If it's easy and does not take much time, I will pump in some other work to practice.

Every morn, I plan the work to be done for the day..sometimes when he comes back with hw which can be done in 15 min, I will get him to do some vocab or synthesis since he has time. If there are days he comes back with lots of comprehension or other English stuff, i steer clear.
At this level, the timetable cannot be enforced too strictly...just good to have a schedule.
With 6 months more to go, I do feel a sense of stress acting up already.

Hi Everyone!


I see everyone is all geared for the new term. Just came back on Tuesday after a 10-day vacation. Life for the kids should be more like that than school, school, school all the time!

Been putting pieces of my "PSLE" life back together again. Yes, we missed school for 2 days. No one said anything. Didn’t see that much homework yet. So still trying to ease ourselves in.

Actually, I’m still mentally not back yet…

Can anyone explain how does SD affect one’s T score? Does higher SD contributes to a higher T score?

Still a bit disorientated. What is SD?

Standard Deviation, which is the spread of marks around the average mark. It can be found on the formula of T score calculation.

Hi mummy so kiasu,

The formula for T Score is 50 + 10*(X-Y)/Z where
X = Child's Marks
Y = Average
Z = Std Deviation

So for e.g., given two subjects with the same average marks and if you child score the same marks for both subjects, then child will get a higher T score for the subject with smaller SD. (Roughly like that ... , correct me if I get it wrong ..)

Regards.

Hi elkniwt, thanks for your reply. Base on what I have just found out, a low SD indicates that the data points are very close to the mean (average), this usually the case for language papers. Whereas, a high SD indicates that the data points are spread out over a large range of values, this is usually the case for Maths paper. If I am not wrong, if the child gets the same mark for 2 different subjects, the T score for the one with higher SD will be higher. Need someone who knows better to explain & confirm.

Hi mummy so kiasu,


If we put in some numbers, it will be easier to see.

Using the formula given T Score = 50 + 10*(X-Y)/Z

Say for example,
Average for both English and Maths = 70
Marks obtained by child for English and Maths = 80
SD for English = 8 and SD for Maths = 16

T Score for English = 50 + 10*(80-70)/8 = 62.5
T Score for Maths = 50 + 10*(80-70)/16 = 56.25

So the subject with a lower SD will have a higher T Score. This is what I think, do correct me if I am wrong.

Regards.

Hi elkniwt,


Thanks for your explaination. I think you are right. Any idea how do they determine the SD?

Take a look at this two links - some information on how to get the SD :
