Summary - 2019 Edition
The unit is subdivided into six learning hours plus an end-of-unit assessment spread across seven lessons in order to fit with most school timetables. It is a theoretical unit covering the latest Cambridge IGCSE® 0478 / 0984 and O Level 2210 Computer Science specification. The conversion of integers from denary to binary is covered in the first lesson, together with the use of binary in computer registers. In the second and third lessons, the use of hexadecimal numbers and the binary representation of characters is described with practical programming exercises to reinforce understanding. Representation of images and sound are covered in two separate lessons with a final lesson covering lossy and lossless compression techniques used for images, sound, video and text. In the final lesson students sit an assessment test comprising questions similar to those found on the IGCSE exam paper.

What people say...
The key strengths of the materials are in their simplicity - you have the content pupils need to know, simply, attractively presented and then a well designed worksheet to test it. The worksheets look excellent and very effective as a tool to cement the learning.
