Re: Vague Goals
AAArgghhh just looked at the detail of just of these ...
10.1 Explain how text, audio, image and video data are stored in binary with compression
• explaining exclusive or (XOR) to develop simple cryptographic ciphers and hashes to ‘secure’ communications
• explaining the use of the Unicode charts to look up characters from Asian languages
• explaining simple compression schemes, for example run length encoding
• explaining the difference between lossy and lossless compression
Dot point 2 - coincidentally I am trying to explain the different encoding techniques and why we have them & my class don't give a rats .... , I had mild interest with ASCII especially when I showed some ASCII art, and total disinterest with unicode - the most common almost printable response was "why can't the ****s just use english characters ?".
From a 30 second glance at just the year 9-10 stuff - it is going to be difficult to develop a coherent program that doesn't do theory for the sake of theory eg we cover some of this stuff already in IST - - dot point is covered in a unit on the internet & protocols, dot point 2 sort of covered in a Software Dev unit, dot points 3&4 covered in a digital media/multimedia unit - where the stuff actually makes sense to teach it.
What hurts most is that Digital technology has become All about software development , and it says multimedia will be taught across subject areas (yeah right - today I had to teach my year 9 class about using styles in a document !) as well as an instance of Design & Tech .
Honestly from a very quick read I think the year 9/10 stuff would make the basis of a great year 11/12 Software Dev course. What I have read assumes greater maturity on the part of year 9/10 than is the case - certainly in my low SES group (ie over 30% of the school is in the lowest income quartile measured on Myschool.com) . The buggers advising ACARA are from selective schools or schools where most students are in the highest income quartile).
Needs a closer read drowning in the motherhood stuff at the start.
