The Computing Progression Pathways suggests that at the purple level, on the theme of programming & development, a student should demonstrate that he/she:

• Understands that programming bridges the gap between algorithmic solutions and computers.(Abstraction)
• Has practical experience of a high-level textual language, including using standard libraries when programming. (Abstraction) (Algorithmic Thinking)
• Uses a range of operators and expressions e.g. Boolean, and applies them in the context of program control. (Algorithmic Thinking)
• Selects the appropriate data types. (Abstraction)(Algorithmic Thinking)

• To be a good computer scientist you have to enjoy problem solving. That is what it’s all about: working out the best way to do things.
