Computer Science


Head of Department : Jonathan Raisin

Staff Contact Details : Natasha Manekshaw

The department is staffed by a fully qualified Computer Science teacher, Mr J Raisin and by Ms N Manekshaw.

The department has three fully networked rooms and further access to a suite of networked computers in the school's library.


The Computer Science curriculum is designed to meet the UK National Curriculum aims. The aim of the curriculum is to develop confident digital citizens who are ready to meet the challenges of the digital world.

Students should feel safe when using technology and the web by learning what their rights and responsibilities are, as well as how legislation can protect them while online but also respecting others whilst in the online realm.

Our students need to understand how to utilise the power of the cloud and cloud based services which can be a powerful collaborative tool - for this we use Google Classrooms.

To find more detailed information regarding the scheme of work for Computer Science, please visit the department Google site.

Key Stage 4


The OCR GCSE (9-1) Computer Science (J277) specification is split into three components:

Computer Systems:

  • Introduces students to the central processing unit (CPU), computer memory and storage, data representation, wired and wireless networks, network topologies, system security and system software. It also looks at ethical, legal, cultural and environmental concerns associated with computer science.

Computational Thinking, Algorithms and Programming:

  • Students apply knowledge and understanding gained in component 01. They develop skills and understanding in computational thinking: algorithms, programming techniques, producing robust programs, computational logic and translators.

Practical Programming:

  • Students are to be given the opportunity to undertake a programming task(s) during their course of study which allows them to develop their skills to design, write, test and refine programs using a high-level programming language. Students will be assessed on these skills during the written examinations, in particular component 02 (section B).

See this link for the official specification

Key Stage 5

OCR GCE A Level Computer Science (H446)

This course has been updated to reflect new and emerging technologies. This course is for students who wish to go on to higher education courses or employment where a deeper knowledge and understanding of computing would be beneficial.

The focus has shifted towards computational thinking within the field of Computer Science, with its emphasis on abstract thinking and algorithmic problem-solving, it is a good foundation for understanding the technological challenges currently facing the industry.

Computer Science is also a practical subject where students can apply the computational thinking principles learned in the classroom to real-world systems.


Year 12

1.1 The characteristics of contemporary processors, input, output and storage devices:
The internal components of a computer and their uses

1.2 Software and software development:
Types of software and the different methodologies used to develop software

1.3 Exchanging data:
How data is exchanged between different computer systems

1.4 Data types, data structures and algorithms:
How data is represented and stored within different structures. Different algorithms that can be applied to these structures

1.5 Legal, moral, ethical and cultural issues:
The individual moral, social, ethical and cultural opportunities and risks of digital technology.  Legislation surrounding the use of computers and ethical issues that can or may in the future arise from the use of computers

2.1 Elements of computational thinking:
Understanding what is meant by computational thinking

2.2 Problem solving and programming:
How computers can be used to solve problems and programs can be written to solve them

2.3 Algorithms: The use of algorithms to describe problems and standard algorithms

Year 13
Extension of the topics studied in Year 12, with the addition of the following topics related to the final year project

3.1 Analysis of the problem

3.2 Design of the solution

3.3 Developing the solution

3.4 Evaluation


Homework is now set through Google Classrooms. To find out more about homework requirements, please visit the Homework section of this website.

E-records of student progress are updated regularly, using Google Classroom and Google Apps for Education.


KS3: Project based assessment using assessment rubrics or multiple choice quiz.

KS4: End of topic written assessment or multiple choice quiz.
