## Prior learning/place of lesson in scheme of work
|
|||
|
|
|
|||
|
|
Learn how to get the **acceleration**, `input->acceleration` in one of three specified dimensions. We will be learning how to get the acceleration using a forever loop, local variables, input on button pressed, as well as simple commands, such as show number and pause.

## Progression Pathways / Computational Thinking Framework
|
|||
|
|
|
|||
|
|
#### Algorithms
|
|||
|
|
|
|||
|
|
* Designs solutions (algorithms) that use repetition and two-way selection, ie if, then and else.(AL)
|
|||
|
|
* Uses logical reasoning to predict outputs, showing an awareness of inputs (AL)
|
|||
|
|
* Shows an awareness of tasks best completed by humans or computers (EV)
|
|||
|
|
* Designs solutions by decomposing a problem and creates a sub-solution for each of these parts. (DE) (AL) (AB)
|
|||
|
|
* Recognises that different algorithms exist for the same problem (AL) (GE)
|
|||
|
|
* Represents solutions using a structured notation (AL) (AB)
|
|||
|
|
* Can identify similarities and differences in situations and can use these to solve problems (pattern recognition)(GE)
|
|||
|
|
|
|||
|
|
#### Programming & Development
|
|||
|
|
|
|||
|
|
* Creates programs that implement algorithms to achieve given goals (AL)
|
|||
|
|
* Declares and assigns variables(AB)
|
|||
|
|
* Uses post-tested loop e.g.‘until’,and a sequence of selection statements in programs,including an if,then and else statement(AL)
|
|||
|
|
* Understands the difference between, and appropriately uses if and if, then and else statements(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)
|
|||
|
|
* Selects the appropriate data types(AL) (AB
|
|||
|
|
|
|||
|
|
#### Communication Networks
|
|||
|
|
|
|||
|
|
* Demonstrates responsible use of technologies and online services, and knows a range of ways to report concerns Understands how search engines rank search results (AL)
|
|||
|
|
|
|||
|
|
#### Information Technology
|
|||
|
|
|
|||
|
|
* Collects, organizes, 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)
|
|||
|
|
* Recognises ethical issues surrounding the application of information technology beyond school.
|
|||
|
|
|
|||

Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
