A presentation to talk students through how to answer questions in GCSE Computer Science to get the best marks. The presentation talks through exam command words and how to interpret how much should be written based on the number of marks available and shows some exemplar answers.
A bundle of 7 knowledge organisers for GCSE Computer Science including:
Computing Hardware
Data representation
Databases
Networks
Programming
Software
The Internet and WWW
In the run up to completing the Programming Project (NEA) for OCR GCSE Computer Science, it is sometimes difficult to track and monitor progress. Students often don’t take suitable notes or keep detailed comments on their previous code to serve as an aide memoire in future programming. This learning diary facilitates student reflection and evaluation of their learning within a lesson and allows progress to be tracked across a series of lessons. It could also be used to support tracking the progress of students within NEA lessons, perhaps as part of a homework.
By the time most students are in Year 7 they are extremely familiar with using computers for entertainment, research and school work. However, very few will have given the computer itself much thought. It is unlikely that they will know the origins of the first electronic computer or how computers have developed over the decades. Although they might have heard of the term, ‘transistor’, very few will know their role or how their development has been predicted by Moores’ Law. Even less will know about how computers process data and switch between tasks whilst working. And whilst they are familiar with the term, ‘software’, do they really know what it means?
This scheme of work aims to provide a gentle introduction for students to the world of computers and computing
