Summary

The unit is subdivided into seven learning hours plus an end-of-unit assessment spread across seven lessons. It is a theoretical unit covering Topic 2 of the 2020 Edexcel Computer Science specification 1CP2. The conversion of integers from denary to binary (including sign and magnitude and two’s complement) is covered in the first lesson. In subsequent lessons, the use of hexadecimal numbers and character encoding is described with practical programming exercises to reinforce understanding. Binary addition including logical and arithmetic binary shifts are also covered. Representation of images and sound are covered in two separate lessons with two final lessons covering lossy and lossless compression techniques and encryption. In the final lesson students sit an assessment test comprising questions similar to those found on the GCSE exam paper.

What people say...

“
”

I am really pleased with the resources for the Unit 8 'Crude Oil and Fuels' so far. As I am non-specialist teaching the new specification of AQA GCSE Chemistry for the first time this year, these resources have been invaluable to me. The presentations are thorough and well illustrated. The teacher guide and power point presentation leads you through the topics logically. This has been particularly useful as I have been tasked with picking up this course with students that are already midway through their GCSE and the commentary has provided me with useful guidance of what students should have covered in earlier modules and there are also activities that recap earlier learning. The fact that the resources are so thorough and there is a WS and HWK for every lesson, has saved me a huge amount of planning time as there is already plenty for students to do. All I have had to do is add a little further differentiated practice as and when my students needed it. I will definitely be looking at buying other modules too.
