KS3 Computing

Germ of this book This book started with a Hack the curriculum event on Saturday 18th April 2015, where volunteers met to start creating this book. It will need lots more help and work before it's ready for general use. Please see the Editing Guide to help and to contribute.

Life changing The Royal Society identified three distinct strands that make up Computing, each of which is complementary to the others: computer science (CS), information technology (IT) and digital literacy (DL). Each component is essential in preparing pupils to thrive in an increasingly digital world. [Diagram here of what computing is] Information technology (IT) is concerned with how computers and telecommunications equipment work, and how they may be applied to the storage, retrieval, transmission and manipulation of data. Digital literacy is the ability to effectively, responsibly, safely and critically navigate, evaluate and create digital artefacts using a range of digital technologies. Computer science is the scientific and practical study of computation: it is the study of what can be computed, what computers are and how they work, and how to develop applications to solve problems. Computer science is different from ICT which is about how to use digital tools and sources of data to process and communicate information. This book is aimed at students in Key Stage 3 but might also be useful to students of other ages. Key Stage 3 is normally students between the ages of 11 and 14 in British schools.
