| 1 | Identify examples of abstraction. | Selecting the pieces of information that are relevant to solving the problem. LINK Thinking ahead. | |
| 2 | Explain why abstraction is required in the derivation of computational solutions for a specified situation. | Students should be aware of the concept of objects, for example, the use of collections as objects in the design of algorithms. LINK • Databases: tables, queries • Modelling and simulation: an abstraction of reality • OOP: classes, sub-classes • Web science: distributed applications | |
| 3 | Construct an abstraction from a specified situation. | There is no need to use code. Levels of abstraction through successive decomposition. A school can be decomposed into faculties. A faculty can be decomposed into departments. LINK Thinking ahead, thinking procedurally. Connecting computational thinking and program design, introduction to programming. | |
| 4 | Distinguish between a real-world entity and its abstraction. | TOK The map as an abstraction of the territory. |
