Computer Science

In this unit pupils will discover computers process instructions. They will recognise the function and tools IDEs provide for developing code and start to develop Python programa which follow a sequence. Pupils will create programs which deal with input and output and make variables to store values.

Programming: sequence

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

In this unit pupils will explore the benefits of good programing practices and why subroutines are used in programs. They will create conditions in programs which use arithmetic, relational and logical expressions. They will develop their understanding of selection and explore nested selection.

Programming: selection

In this unit pupils will discover the difference between general purpose and embedded systems. They will examine computer architecture and the components that make up a processor. Pupils will recognise the need for storage and be able to select a suitable storage device for a given purpose.

Computer Systems

In this unit pupils discover how iteration is used to replicate parts of a program. They will analyse the difference between count and condition controlled iteration and how trace tables can be used to trace through loops. They will explore data validation techniques and robust program design.

Programming: iteration

In this unit pupils will discover that Boolean logic is a way of describing circuits inside a computer. They will recognise logic gates as the building blocks of processors. They will be able to construct logic diagrams, truth tables and simplify Boolean expressions.

Boolean logic

In this unit pupils will be reminded of how the base-10 number system works before being introduced to the base-2 number system. They will perform conversions between binary and decimal and recognise the rules of binary addition and subtraction. They will be introduced to hexadecimal and its uses.

Representation of numbers

In this unit, pupils will discover how letters, images and sounds are represented with binary digits. They will also explore the factors that impact the quality of those representations and investigate the effects these quality choices have on file size.

Representation of text, images and sound

In this unit pupils will have opportunities to analyse, interpret, modify, and implement a range of searching and sorting algorithms. They will have the opportunity to compare the features and efficiency of these algorithms and make suggestions about the most suitable algorithm for a given task.

Searching and sorting algorithms

In this unit pupils will be introduced to the concept of data compression and why it is needed. The will compare lossy and lossless compression methods and their typical uses. They will have the opportunity to compression methods such as run length encoding (RLE) and Huffman coding.
