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.

This presentation is a follow on after students have already learnt about how the Fetch Execute Decode Cycle. The idea of the presentation is that they can flow on from what they've already learnt. This will focus on the AS Level - Von Neumann / Harvard systems and it explains the difference. Following on from this the students are taught the difference between CISC and RISC. The idea of this will be that they understand how instructions are split. There is a task at the end with requirements for students to build a revision poster at the end.

(0)
This lesson starts off with some previous exam questions about LAN and WAN. It includes answers and shows students where they can gather their marks. It then explains to students how a protocol works. It gives them an example and gets them to think about their communication. Following on from this there is a video explaining the TCP/IP stack with the 4 layers that they're likely to need to know. Each layer is broken down into key points. There is a single exam style question. Students are then expected to look up the remaining protocols which are used regularly in networks. This task can be through poster, video or other medium.

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.

Break down of floating point binary (How to do it) - A-Level Computer Science / Computing

(1)
Many of my students struggled with the concept of converting from denary into floating point binary. This presentation shows a variety of question and breaks down how to tackle the questions. There are 5 sample questions at the end of the presentation for students to attempt and the technique is broken down into simple steps to help both the teacher and the students understand it. It breaks down how to do some simple questions such as number 7 but also shows you how to work out negative numbers such as -0.375 and shows the technique for multiplying the decimal by 2. I hope that this will help struggling teachers.

Sound Representation & Data Representation

(0)
This worksheet introduces sound to the students. They’re expected to answer a series of questions which talk about analogue sound, bit rate and bit depth. There are questions included which build on knowledge that they may have previously covered. For example, ASCII and Unicode. There are also questions about lossless and lossy compression included which support the need for compression on files.

This lesson will introduce to students how they're able to sequence and talks about how they're able to make code more efficient. There are teacher notes and there is information about advanced selection. This lesson will introduce Tinker time and will get the students to use pages within Kodu. Students will continue to work with Kodu after this to complete their game.

This scheme of work is purely a way of structuring some of the content for primary of secondary. There is examples of selection, moving and how to clone objects within the game. The first 3 lessons come with evidence worksheets and it's broken down in such a way to help you support your students. Students are encouraged through this scheme of work to develop a game but also to take regular print screens of testing their game. I have included all worksheets and powerpoints and there are lesson plans. The lesson plans are basic but show how to split the lesson into tasks. There is a free lesson to give you an idea of what to expect.
