Computer Science and IT
Why study Computer Science?
Computing and computer technology are part of just about everything that touches our lives from the cars we drive and the movies we watch, to the ways businesses and governments deal with us. Understanding different dimensions of computing is part of the necessary skill set for an educated person in the 21st century.
How will I study Computer Science?
Pupils study Computer Science through substantive and procedural knowledge. The curriculum teaches pupils to use computational thinking and creativity to solve problems. Pupils will learn the principles of information and computation, how digital systems work and how to create programs and systems of their own using high-level programming languages. As a result, our pupils will become responsible, competent, confident, and creative users of information and communication technology, with the skills to solve problems, design systems and understand human and machine intelligence. They will learn how to apply the academic principles they learn in the classroom to real-world systems in an exciting and engaging way.
What will I study at Key Stage 3?
Students in KS3 will explore computer systems and digital devices, including both physical and digital components. They will master problem solving through using computational thinking and create algorithms to solve problems. The curriculum introduces students to text-based programming with Python. The lessons form a journey that starts with simple programs involving input and output, and gradually moves on through arithmetic operations, selection, iteration and string manipulation. Students develop essential knowledge on binary representations and how computers translate human interaction. Students are introduced to binary digits and how they can be used to represent text and numbers.
Students go on to develop their understanding of information and digital literacy skills. Students will develop software formatting skills and master spreadsheet skills including the use of formulas and functions. Students look at social engineering techniques used by cybercriminals and how to prevent these threats. This is followed by students exploring the technologies that make up the internet and the World Wide Web.
What will I study at Key Stage 4?
At Key Stage Three pupils study either Computer Science of Digital Information Technology.
OCR GCSE Computer Science
During the GCSE Computer Science course, students will develop an understanding of Computer Science methods in the real world, providing you with a real study of computation and reflection on today’s global world.
Students will study principles of computer science and application of computational thinking. Following on from more visual programming environments, programming skills will be developed further using high-level textual programming languages.
BTEC Digital Information Technologies
The BTEC in Digital Information Technologies develops pupils’ understanding of IT skills through the development of creative products to solve real world data problems. Taking this qualification will prepare pupils for a career in a data driven future. Learners will understand and develop tools, techniques, methods and processes for technological solutions; knowledge and use of hardware and software applications; Data Manipulation tools and techniques; and project life cycles – phases, interaction, inputs and outputs; and risks, legal moral, ethical and security issues.
Assessment at Key Stage 4
GCSE OCR Computer Science J277
J277/01: Computer systems
| Overview | Focus |
|---|---|
| Written paper: 1 hour and 30 minutes 50% of total GCSE 80 marks |
Systems architecture, memory and storage, computer networks, connections and protocols, network security, systems software and ethical, legal, cultural and environmental impacts of digital technology The question paper will consist of short and medium answer questions. There will also be one 8-mark extended response question |
J277/02: Computational thinking, algorithms and programming
| Overview | Focus |
|---|---|
| Written paper: 1 hour and 30 minutes 50% of total GCSE 80 marks | Section A is worth 50 marks, and assesses students’ knowledge and understanding of the concepts of Computer Science. Students then apply these to problems in computational terms, where they may use an algorithmic approach. Section B is worth 30 marks, and assesses students’ Practical Programming skills and their ability to design, write, test and refine programs. |
BTEC Digital Information Technology Edexcel
| Overview | Focus |
|---|---|
| Component 1 – Exploring user interface | Design principles and project planning techniques using web authoring, app development or database software. |
| Overview | Focus |
|---|---|
| Component 2 – Collecting, presenting, and interpreting data | Raw data is provided, learn how data becomes information and how data is collected using primary/secondary sources. Data is prepared and presented using spreadsheet or database software, show how the data then can be presented using pivot charts and formatting techniques. |
| Overview | Focus |
|---|---|
| Component 3 – Effective Digital Working Practices | Exam unit which is 1 hour and 30 mins. This external component builds on the knowledge, understanding and skills acquired and developed across the qualification. It requires learners to select and integrate knowledge and understanding synoptically from all components. |
Enrichment
The department offers subject-specific enrichment clubs and pupils are able to use the school’s state-of-the-art IT facilities. Pupils are able to take part in representing the school in local and national competitions designed to increase their engagement and enhance their subject knowledge, such as the CyberFirst Girls’ Competition.
Careers
IT skills and knowledge are useful in whichever direction you choose to embark upon.
Possible career choices are: Network Manager, Web Development, Software Engineering and Architect, Data Analyst, Data Science, Cyber Security, Project management, accountancy and Teaching.
