No, giving enhancement subjects full study scores is not a solution. This is primarily because they do not involve a full subjects workload. about 3 hours of study including lessons per week can get you a high distinction/first class honours.
Excessively high scaling is also not a good way to entice people to do maths and physics. Take the example of languages, which I believe get scaled up five more than they should as a government plan to bolster language studies. Whilst this a benefit to apt students, students who really struggle take the subject for the scaling and then get below 25. They would, (and the VCAA VCE brochure agrees) be better off doing a subject they enjoy. If UMEP were a normal subject, with a full workload, it would be scaled by at least 15. Such a number would attract many Specialist students who couldn't cope with the maths understanding along with digesting Specialist.
and these people would soon realise this.
what should not be ignored is that teachers arent automatic robots, and you dont just pick your subjects, there is such thing called "career conselling", which involves teachers who know your abilities talking to you about what subjects you can and should do.
a student picking this subject beyond their level do so at their own peril, its not like they have no information about it at all.
Furthermore, this would discourage people from spreading their subjects across various fields. It would mean that someone could have 3 maths subjects that scale up in their top 4. The IB, one possible example for modern education standards requires a diverse course selection. Adding another high end mainstream math detracts from the diversity you can find in a VCE course.
such a system is already in place: only three mathematic subjects count towards the ENTER. there is nothing wrong with having three subjects scale up in the top 4, it just means this person is a capable student who is well suited for some awesome degree.
also keep in mind that prerequisites towards particular courses should not be ignored. say for medicine, whilst a person may buff up with three maths, chemistry and english are still prereqs, its not as if there is no compulsory diversification.
another key point should be noted is that not many people will have the enthusiasm to pursue three concurrent math enrolments. true that some people will exploit the advantages, but few will have the mentality to keep this up. simply put, people arent all crazy and fatalistic [sorry
] like some of us, and this option allows those who enjoys math to develop their potential and their achievements valued.
So, this is why having enhancement subjects scale is a bad idea. They are an enhancement to the VCE, not the VCE itself and should be regarded as such. Given the structure of scaling, were they to be taught, the VCE system would have to be overhauled.
BTW, I eagerly await a response, devil's advocate is my favourite game
VCE should be overhauled, I have no wish to be compared to an Arts student [for example], ENTER is not the best system
and LOL, devil's advocate is always fun
