[Design and Technology] destech Digest, Vol 174, Issue 11

Hi all

I agree with Brendan. Also, I have always been concerned by the fact that the key knowledge for unit 3 outcome 1 is intended by VCAA to be learned by the student in the process of designing and commencing production of a mechatronic system with control. The reality is that this key knowledge also needs to be taught as theory.
The study design lists more than 58 different components, concepts and principles as key knowledge in unit 3 outcome 1. There is no indication as to what level of understanding the student is expected to come to during the course yet it is this very list of concepts and principles that the exam is almost entirely based on. I find this level of ambiguity even more alarming than degree of difficulty pointed out by Brendan.
The student then faces the daunting prospect of sitting the paper not really knowing if they are fully prepared. Russian roulette.
I think it’s a great study. But there needs to be more clarity regarding the depth that the student is expected to have in the concepts listed.

Thanks for starting the discussion Brendan,

I agree with you that there are some questions that are quite difficult. But I recognise there needs to be difficult questions as a discriminator at the high end of achievement.

A couple that I'm interested in:
I'd be interested in seeing how Q3 was interpreted by students. Depending on how it's marked, there may be a bunch of 2/3 marks for that one. I'm not certain how the writers intended the initial connections to be done. The rest should be straight-forward for a high-achieving student.

Q4 could be interpreted in a bunch of different ways; particularly the mistake questions. I’d be interested in your interpretation of this question.

Whilst there is always going to be disagreement of what is "too hard for school students", the biggest misstep (in my opinion) is the over-emphasis on purely calculation-type questions at the expense of questions where students have to design a system to solve a problem/meet a set of performance specifications. I don't know if this was a panel-level decision or a VCAA-level decision, but that type of problem solving is core to what engineering is. From the study design: "identify and represent mechanical and electrotechnological systems in diagrammatic and symbolic forms", and "select appropriate mechanical and electrotechnological subsystems, materials and components, and produce operational systems and subsystems".

Interested in getting others' thoughts.

Cheers

Good afternoon,

I have just been reading through and working out some of the answers for todays unit 3/4 Systems engineering exam.

Has anyone else been through it?

It seems to be extremely difficult and at times way above the level of knowledge required for secondary students.
I am an electronics engineer (now systems teacher) and I really think the level of skill required was excessive for this exam.

Written by someone from a university?

What do other Systems teachers think about the exam content, wording and examples?
