Summary

The unit is subdivided into six topics, expected to be taught across roughly six weeks of lessons, plus a test, in order to fit with most school timetables. It is a theoretical unit covering the relevant sections of the AQA AS Level Computer Science specification. The unit is designed to allow AS students to be taught at the same time as students taking the full A Level.

Six topics in this unit cover data representation of numbers, text, images and sound, with the final topic explaining and giving examples of the uses of data compression and encryption. The beautifully illustrated PowerPoint slides, interactive style of the lesson plans, challenging and imaginative worksheets and graded examples in the homework will all help to ensure the class is fully engaged.

PG Online have identified an incredible opportunity for efficiency savings in the school system. The use of existing technologies, which teachers are likely to be familiar with, greatly reduces any potential for a digital gap to evolve.
