Do you think it's time for standardization? Or perhaps VCAA should introduce questions that will require you to write/read snippets of code in the exam?
It seems they are beginning to move towards having to write code with the pretty simple questions they had on the 2012 SD Exam. They've had those snippets of pseudocode to read and pick out errors in for years too. The more important question is when will they make those questions more challenging?
I'm not sure about standardisation, especially given how each person has an argument for which language they think would be appropriate for teaching, teachers may feel stronger in a particular language and probably also vary depending on the strength of the students (e.g. you wouldn't want to throw Java or C++ at students who haven't had any programming experience at all). Cutting down the number of programming languages into VB.NET, Python and Java or C++ would probably cover the major 'flavours' of programming languages that on the list of languages to choose from.
If we were to settle on one language to teach, I'd probably go with Python since that's pretty good for teaching beginners but still has enough substance/used enough elsewhere for more experienced students to play with.
Standardisation would mean that they could throw actual programming code on the exam, rather than whatever system for pseudocode they're using and seemingly making up as they go along. I'm not really a fan of that either, if you're going to write pseudocode like VCAA writes you may as well be writing the code from scratch
