Computer Science

a visual representation of an algorithm or program

a sign, shape or object that is used to represent something else

to make one thing the same as others of that type

Representing algorithms using flowcharts

Computational thinking

Comparing algorithms to computer programs

Representing algorithms using pseudocode

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 diagram that uses symbols to document the logic of an algorithm

to visually represent the logic of a process

Yes, flowcharts must always be created before writing any program.

Yes, flowcharts replace the need for writing code.

No, flowcharts are only used for simple programs.

No, simple programs may not require a flowchart.

Is it always necessary to create a flowchart before writing a computer program?

they allow for visual representation of logic and data

they are written in programming languages

What is the main advantage of using flowcharts?

It makes flowcharts easier to read and understand.

It limits creativity in designing flowcharts.

It ensures flowcharts are written in code.

What does standardising flowchart symbols achieve?

What is used in flowcharts to connect symbols and show the flow of the process?

a structured approach to solving problems

to focus on the important details of a problem

What is the purpose of abstraction in computational thinking?

they are written in a programming language

they can be implemented in different computer programs

Which of these is **not** true about algorithms?

What is the system of rules that determines the flow of instructions in a process called?
