This task is a worksheet which explains the rules for bitwise operators and it explains some situations of where you might use it. On top of this it gives you a number of questions with an answer sheet which will help support your lesson. It explains the rules of AND, OR and XOR which are on the OCR A-Level Computer Science Syllabus.

This slide deck includes software development. It looks at the following content through these slides;- *Feasibility *Requirements *Waterfall life cycle *RAD *Spiral *Agile There are some questions are the end and a link to a YouTube video showing me teaching it. It should help you with your delivery.

As part of the OCR GCSE Computing syllabus, students are expected to learn about bitmaps and they're expected to learn all about how images are represented. This worksheet helps students answer a series of questions on image representation. Sample questions include: - How does the resolution of an image effect the size of the file? What metadata is stored with an image file? There are more but you can get an idea of what this worksheet covers.

This is a personal learning checklist for algorithms and programming in computer science A-Level OCR. It will help candidates evaluate how strong they are at specific areas of the subject. This can be used to monitor progress.

This is an end of topic test on specific areas of the CPU for students to use. Questions are taken from previous years with the mark scheme attached. There are 4 pages to the test. It includes questions on the following areas of the CPU: - MAR (Memory Address Register) PC (Program Counter) Buses used ALU (Arithmetic Logic Unit) Fetch - Decode - Execute Cycle Registers Accumulator Memory Data Register

This Powerpoint covers 1.4.1 (g) - Representation and normalisation of floating point numbers in binary and 1.4.1 (h) - Floating point arithmetic, positive and negative numbers, addition and subtraction. This presentation shows you step by step how to convert two numbers into floating point binary and it shows you the steps to do it. There are 5 questions at the end which will test your understanding and will give you the answers. There is an example exam question for adding floating point binary numbers and it's broken down to show how to get the marks and how to get there. The PowerPoint is plain white and isn't exactly appealing to the eyes but it shows you clearly what happens during each point.

These 7 slides introduce artificial intelligence to students. It includes two basic worksheets with answers and helps the students to get a little deeper in their thought behind how artificial intelligence learns.

Week 5 - Encryption Objective: - •To identify some of the data which should be kept secure from others. •To learn some of the ways in which data is kept secure. •To learn how unauthorised people can break ciphers and read encrypted data. •To learn about classical encryption techniques. ​Task 1 : - Come up with a list of data which would need to be kept secure. Task 2 : - Your teacher will print out this worksheet for you. They can click here to download it. You should use this file to help solve the message. Click here Task 3: - You are now going to learn a little bit about brute force and the Caesar shift. •https://vimeo.com/145990347 - Watch this video and find out more about the Caesar Shift. ​ Complete the worksheet using the PowerPoint's: - Click here

This presentation gives example code and show class diagrams. It teachers students about: Procedural Object-Oriented Declarative Students are also explained to and taught about: - Inheritance Polymorphism Constructors Inheritance Advantages

This Micro:bit lesson introduces to students how they can build a magic 8 ball using the microbit. Before they start building a magic 8 ball, students are introduced to how to use the A + B buttons and they're introduced to how to build a flow chart. They complete a simple cup of tea. Once they've complete a flow chart they will attempt to create one for a simple A + B program. After this they will work on a magic 8 ball. There is a video included which shows you how to do the random number generator for the magic 8 ball. This should give students the basic skills that they need for planning and it includes videos which will help them understand it.

Objective: - We’re learning how to add binary and develop an understanding of hexadecimal. Students will be given a break down of how to add resources together. Where topics may have been a little tricky, I have included notes in the Powerpoint slides to help new teachers. I've tried to include hand drawn sketches in the presentation. This resource includes worksheets and answer sheets. There are two activities to complete and this lesson could take you across two lessons with the answer sheets and discussion. Covered in the slides: - Rules for adding using binary Showing how to add binary numbers Diagrams to help students Overflow information Explanation of what overflow is Worksheets How hexadecimal works Break down of how to convert into hexadecimal Content written by National Teaching Award winner: - Ray Chambers 2015 - Innovative use of technology.

This is a project sheet which will help students plan and make a project. It is a tick sheet that will help you deliver a project over a number of days. Students can come up with their own project and the requirements are mapped against the OCR requirements. This means that they will have a run through of what is expected before completing a task.

This is a simple task which will allow students to create a simple user interface in Python. It uses the Tkinter library which is built into most schools. They're able to create some simple procedures which quit and display error messages. It shows candidates how to add in buttons and gets them creating a simple interface in Python which they can use for programming. The idea of this is to get A-Level students started so that they can start thinking about using Python for their main project. It is suitable for GCSE and Lower Level students.

4 questions with mark scheme attached showing students what they're expected. Questions are on the clock speed, cache memory, multiple cores and how the cache works. This is a simple starter activity that will test knowledge from a previous lesson.

These posters have been made to help students program using Python. The idea of these posters is that you can laminate them and put them on a desk so that students can help themselves. I use these in my lessons as a way of encouraging students to try new things when programming. I wanted them to understand the code better and they were able to try out the code on each of the boards as extensions and I was able to put these on display. Some of the poster included in this bundle are: - *float *if statements *joining strings *strings to integers *using variables *loops *numbers

This activity sheet breaks down how you can subtract binary numbers. It comes with the entire answer sheet and also shows candidates how to subtract in a step by step walk through. It talks about how you flip the bits and work out your answer. The answer sheet is clear and coloured so that you can spot the answers.

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.

Objective: - We’re learning to explain how compression methods are used in computer systems. Outcomes: - Lossy vs Lossless compression – Understanding it’s uses. Run length encoding and dictionary coding for lossless compression Symmetric and asymmetric encryption Different uses of hashing This covers the introduction to Lossy vs Lossless and talks about run length encoding and encryption. Includes a link to a khan academy video on encryption from YouTube * Referenced *

This work sheet is a number of questions including extension activities that will get students to program pseudocode on paper. The first part of the work sheet includes some basic questions as well as some answers on an answer sheet. It should be some good practice for the basics of pseudo code. The extension questinos are more complicated and should be done on a separate sheet or work book as practice for the students.

Slide 1 - Title Slide 2 - Objectives explaining that students will learn about clones and creatables. They will know the difference between the two. Slide 3 - What is cloning slide with a built in text box so that the teacher doesn't have to come out of the slide. You can make notes finding the difference by discussion with the students. Slide 4 - Think about how computer games might use cloning and discuss. Slide 5 - Shows how to clone. Slide 6 -How to load up the creatable. Slide 7 - Shows how to make a rock a creatable. Slide 8-10 'Tinker' time and some ideas to get the students started.
