Sir John Leman High School & Sixth Form

Computer Science will enable students to:

• Acquire and apply knowledge, some technical skills and an understanding of the use of algorithms in computer programs to solve problems using programming in a range of contexts. Mathematical ability and understanding is important to enable success in this course. For this reason we require the students to be in sets 1-3 in Mathematics.
• Use their knowledge and understanding of computer technology to become independent and discerning users of IT, able to make informed decisions about the use and awareness of the implications of different technologies.
• Develop computer programs to solve problems. It is very important that students are resilient and persevere in problem solving. They will develop the skills to work collaboratively.
• Evaluate the effectiveness of computer programs/solutions and the impact of, and issues related to, the use of computer technology in society.

This course is suited to students who want to go more into the side of IT.

Unit 01 – Computer Systems

The first component is an exam focused on computer systems covering the physical elements of computer science and the associated theory. This unit will cover: Systems architecture, memory, storage, wired and wireless networks, network topologies, protocols and layers, network security, system software and moral, social, legal, cultural and environmental concerns.

Unit 02 – Computational Thinking, Algorithms and Programming

This component is focused on the core theory of computer science and the application of computer science principles. This unit will cover: Translators and facilities of languages, algorithms, high- and low-level programming, computational logic and data representation, programming techniques, design, development, effectiveness and efficiency, technical understanding, testing, evaluation and conclusions and a programming challenges and a programming project.

By examination. Units 01 and 02; Computer systems and computational thinking, algorithms and programming units are assessed by examination and worth 50% for each of the two exams.
