The Computing Progression Pathways suggests that at the yellow level, on the theme of Data & Data Representation, a student should demonstrate that he/she:
- Recognises different types of data: text, number. (Abstraction) (Generalisation)
- Appreciates that programs can work with different types of data. (Generalisation)
- Recognises that data can be structured in tables to make it useful. (Abstraction) (Decomposition)
