Specialist Math scaling

[Natters]

My spesh teacher found me today to tell me she'd heard that it will be getting marked up "elevenish" instead of the expected 8, she said it was reliable and seemed sure of it but im very skeptic, anyone else heard something about this?

edit:
just adding this for people who view the thread for shits and giggles
a few people have said it's likely to go up due to the specialist students not being compared to the year 11 methods students (who are generally higher achievers) in the past, which is beginning this year, or smth like that;

heres this guy explaining it better than i could

sros-

Take this as a grain of salt, as it is derived from reading and hearsay...

From what I can gather; scaling works on a principle of comparing the relative raw scores of all of the subjects every student within a subjects cohort (eg: spesh) undertakes, thus allowing them to come to a conclusion as to the difficulty of the subject (spesh).

For example, within Spesh they notice that the cohort of spesh is considered 'smart' as much of the students who get a 30+ raw in spesh get low-mid 40's in their other subjects. Hence it can be gathered that spesh must be 'difficult' and using modelling they can accurately determine this 'difficulty' from using each individual students data and hence scale the subject according.
(This is also as to the reason why scaling differs slightly each year, as the cohort is as a mean slightly differing in 'intelligence' each year)

For the 3 maths though, they never include the subjects the student undertook in year 11 (most often methods) to assist in this calculation of 'difficulty'; this is crucial as most specialist students go quite well in methods in year 11, and by not including this high score they are in a way decreasing the 'mean' intelligence of the spesh cohort.

Hence, since this 'mean intelligence' was slightly lower since not including methods, the scaling for spesh was scaling slightly lower than if they had included this methods score.
Thus now that they are including methods, it is predicted (using their modelling) that the 'mean intelligence' of the cohort will rise, hence leading to the subject appearing more difficult (the intelligence of the cohort suddenly rises but the average scores will be the same this year from the last) meaning that theoretically (and based from their modelling) the mean will now rise from 38 scaled, to 41 scaled.

This is true. My class was informed by our spesh teacher today. A 30 will be scaled to around 41 since apparently they haven't been considering Year 11 MM 3/4 study scores when scaling.

So great news for us.

You realise that you cant predetermine how much a subject will scale by?
It depends on all the stats etc as it is compared to other subjects and what not.

But yeh lets hope it goes up 12? XD

[Natters]

oooh thats a confirmation
this pleases me =)

and there can still be estimates afaik
score!

LOL,

this is completely false.

I also had some information from our teacher today about the proposed change, it is quite brief, but here is the information:
http://www.vtac.edu.au/pdf/publications/bulletins/bulletin4-11.pdf

Edit, for those to lazy to read!:

"Modelling indicates the changes are likely to increase the scaled mean of Specialist Mathematics by
approximately three, with no observable effect on other subjects."

"VTAC will implement these changes in December 2011 for the
scaling of VCE studies for the calculation of the 2011 ATAR."

Of course it's not definite, but predictions are made by an official source:

"Modelling indicates the changes are likely to increase the scaled mean of Specialist Mathematics by
approximately three, with no observable effect on other subjects."

*shrugs* I'm happy with that...

HOLY FUCKING SHIT/

<3 DIS SHIIET.

[Greatness]

Oh wow... it might just scale by 11 this year...

If this doesnt affect the scaling of other subject study scores, does that mean specialist students will have an advantage over non-specialist students - as in they will have an edge aggregate wise?

[onur369]

Why specialist ? Many say spesh is getting easier and methods is getting harder ? Mind you I didnt bother reading the article.

[Greatness]

because there is some correlation between more students doing all three maths now, so that they can scale them against each other or something like that - im not too sure either.
