Writing and testing algorithms

Computing

In this unit pupils will use physical computing to explore the concept of selection. Pupils will use conditions to control the flow of a program. They will make use of their knowledge of repetition when introduced to the concept of selection and write programs that utilise this concept.

Exploring selection in physical computing

a loop that repeats commands indefinitely

a precise sequence of steps to complete a task

Why is it important to test small parts of code frequently?

it helps plan the steps needed to complete a task

Why is an algorithm important in programming?

find the part of the code causing the error

test the program to ensure the error is fixed

Arrange the steps for debugging a program:

a program where one or more commands are run multiple times in a loop

a part of a program where if a condition is met, a set of commands is run

a condition that always evaluates to True

running commands multiple times in a loop

stopping the program when a condition is met

What does repetition mean in programming?

Is a Sparkle an input device, an output device or neither?

What is the process of finding and fixing errors in a program called?

Arrange the steps for creating a coding project:
