[Informatics] ERD Notation

Sat Oct 30 06:20:03 UTC 2021

My students were all quite pleased with the 2021 Data Visualisation Exam. Feedback has been generally positive. I prepared an Exam Prep video orientation that was loosely based on some of the learning shared by the DLTV VCE Team, resource kit and upon earlier work by Gary Bass.

One noted the same, that there was a surge of dynamic data visualisations but after some reflection, un-muddled it from interactive data visualisations and plain old infographics. I’ll have to make this clearer in future.

I am not able to peek at a copy of the 2021 exam myself so I’ll have to wait for our VCE coordinator to mail over a spare or the VCAA to publish it online next year.

Regards Roland
