Computing

Aims:

·         Gives learners a real, in-depth understanding of how computer technology works

·         Provides excellent preparation for higher study and employment in Computer Science

·         Develop critical thinking, analysis and problem-solving skills.

·         Learners will apply the academic principles learned in the classroom to real-world systems.

Staffing

·         Mr Creed – Teacher of KS4 Computing

·         Mrs Watts- Teacher of KS4 & KS5 Computing

·         Mr Pillay – Lead teacher of Computing

A453: Programming Project

Students will need to:

• Understand standard programming techniques

• Be able to design a coded solution to a problem including the ability to:

                - Develop suitable algorithms

- Design suitable input and output formats

- Identify suitable variables and structures

- Identify test procedures.

• Create a coded solution fully annotating the developed code to explain its function

• Test their solution:

- To show functionality

- To show how it matches the design criteria

- Identifying successes and any limitations.

 

Controlled assessment

Programming task. Design, develop and test a solution to a problem within the OCR-set scenario.

KS5 overview

The Computer Science course at KS5 consists of three components.

01 COMPUTER SYSTEMS

This component will be a traditionally marked and structured question paper with a mix of question types: short-answer, longer-answer, and levels of response mark scheme-type questions. It will cover the characteristics of contemporary systems architecture and other areas including the following:

• The characteristics of contemporary processors, input, output and storage devices

• Software and software development

• Exchanging data

• Data types, data structures and algorithms

• Legal, moral, cultural and ethical issues.

02 ALGORITHMS AND PROGRAMMING

This component will be a traditionally marked and structured question paper with two sections, both of which will include a mix of question types: short-answer, longer-answer, and levels of response mark-scheme-type questions.

SECTION A

Traditional questions concerning computational thinking:

• Elements of computational thinking

• Programming and problem solving

• Pattern recognition, abstraction and decomposition

• Algorithm design and efficiency

• Standard algorithms.

 

SECTION B

There’ll be a scenario/task contained in the paper, which could be an algorithm or a text page-based task, which will involve problem solving.

03 PROGRAMMING PROJECT

Students select their own user-driven problem of an appropriate size and complexity to solve. This will enable them to demonstrate the skills and knowledge necessary to meet the Assessment Objectives. Students will need to analyse the problem, design a solution, implement the solution and give a thorough evaluation.

Assessment
