My name is Ray Chambers. I'm a specialist in computing and have a first class honours degree in computer science. I'm currently the lead teacher of computer science at Brooke Weston Academy in Corby Northamptonshire. I have been teaching for roughly 8 years and I thoroughly enjoy my job. In 2015 I was fortunate to win the Pearson National Teaching Award for innovative use of technology. I also won the BAFTA for mentoring young coders.
A Powerpoint presentation explaining Big O Notation. There are some examples of code and some graphs which help students visualise what is meant by exponential and the complexity of algorithms.
This was useful to my year 13 students and hopefully it will help yours.
