digital technologies
Stage 3
|
A student:
Stage 3 of the Digital Technologies strand focuses on understanding the role individual components of digital systems play in processing and representing data. Students design, modify and follow algorithms involving branching and iteration. Stage 3 of this strand further develops students’ knowledge and understanding of project management, abstraction and the relationship between models and the real-world systems they represent.
