Computer Science

a way of expressing an algorithm that is independent of a specific programming language

to convert something from one form to another, making it understandable or usable in a different context

Representing algorithms using pseudocode

Computational thinking

Comparing algorithms to computer programs

Representing algorithms using flowcharts

Tracing algorithms

Data structures

Algorithmic bias

Tackling a project using computational thinking

In this unit pupils will discover the computational thinking techniques; decomposition, abstraction and algorithmic thinking. They will reflect on differences between algorithms and computer programs and explore how algorithms can be represented. Pupils will explore the impact of algorithmic bias.

Algorithms

a way of expressing an algorithm in plain language

Why can't pseudocode be directly executed by a computer?

a human-readable way to outline an algorithm

Which of these best describes pseudocode?

What does it mean to translate pseudocode?

Why is pseudocode useful in problem solving?

to represent algorithms visually using symbols

Which of these symbols is used to represent a decision in a flowchart?

Why is it important to standardise flowchart symbols?

What does a rectangle symbol in a flowchart represent?

Which of these is **not** a benefit of using flowcharts?
