## Progression Pathways / Computational Thinking Framework
|
||
|
|
|
||
|
|
#### Algorithms
|
||
|
|
|
||
|
|
* Uses logical reasoning to predict outputs, showing an awareness of inputs. (AL)
|
||
|
|
* Understands that iteration is the repetition of a process such as a loop. (AL)
|
||
|
|
* Represents solutions using a structured notation. (AL) (AB)
|
||
|
|
|
||
|
|
#### Programming & Development
|
||
|
|
|
||
|
|
* Creates programs that implement algorithms to achieve given goals. (AL)
|
||
|
|
* Uses a variable and relational operators within a loop to govern termination. (AL) (GE)
|
||
|
|
* Uses a range of operators and expressions e.g. Boolean, and applies them in the context of program control. (AL)
|
||
|
|
|
||
|
|
#### Data & Data Representation
|
||
|
|
|
||
|
|
* Understands the difference between data and information. (AB)
|
||
|
|
* Defines data types: real numbers and Boolean. (AB)
|
||
|
|
|
||
|
|
#### Information Technology
|
||
|
|
|
||
|
|
* Collects, organises and presents data and information in digital content. (AB)
|
||
|
|
* Makes appropriate improvements to solutions based on feedback received, and can comment on the success of the solution. (EV)
|
||
|
|
|
||
|
|
Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
