The Computing Progression Pathways suggests that at the white level, on the theme of Data & Data Representation, a student should demonstrate that he/she:
- Performs operations using bit patterns e.g. conversion between binary and hexadecimal, binary subtraction etc. (Abstraction) (Algorithmic Thinking) (Generalisation)
- Understands and can explain the need for data compression, and performs simple compression methods. (Algorithmic Thinking) (Abstraction)
- Knows what a relational database is, and understands the benefits of storing data in multiple tables. (Abstraction) (Generalisation) (Decomposition)
The following link to cs4fn articles that illustrate Data & Data Representation – White Level
- Data compression helps get information small enough to be transmitted quickly, so we can download texts movies and music.
More of our resources, including linked computing ‘story’ booklets can be found in our resources section. You may also want to look at cs4fn’s teacher resources or browse the latest cs4fn magazine.
