This topic introduces data structures such as: - *Arrays *Stacks and Queues *Records *Lists *Tuples There are over 22 slides with some code for algorithms to support how stacks and queues work and how they check whether the queue is full. It should help your students understand the different data structures used in computer programming.

This is a pack of resources which are available to purchase individually. In this pack are some worksheets which break down data types in the OCR A-Level computer science. This is for section 1.4.1 of the Data types, data structures and algorithms. Included in this pack is: * Binary addition * Binary subtraction * Fixed point binary * Floating point binary * Normalisation of floating point binary * Bitwise operators All sheets come with answers for your own ease of use

This set of slides is over 45 slides long. It introduces the basic logic gates and basic boolean algebra. It shows how to simplify boolean. There are over 45 slides showing K-Maps / Karnaugh Maps and they show how you can spot the patterns and show what the answers should be. At the end of the slide there are two links to YouTube videos I have made of these slides showing it being taught. It should have a break down of some computing problems which should help you.

This tutorial introduces SQLite3 and databases to A-level students. It helps them do computer programming and helps them to create a database. it shows you step by step how to do queries and how to get the information to show up on the screen after a search. It is 6 pages long with print screened examples on how to complete the activity. It does not include buttons to navigate but it is a good starter project for helping your A-level students.

This is a series of 3 activities which introduce the user interface library tkinter to students. It helps them build a simple user interface that looks at a text file. The first worksheet introduces them to text boxes and buttons. This is fairly straight forward. The second activity starts building a simple database using a text file that will read and write information. The third activity builds on task two and shows how to navigate back through the records and it allows the student to delete a record from the text file. It allows people to add more records to the file but it also allows people to read information from a file. This the basis for building on and using an actual database later on. There are some final solutions attached through the zip files which will help you on your computer.

These questions will help your students with answer exam style questions on legislation. 8 Pages including an activity sheet and some exam questions I would include on an enable table in the corner of the room. Usually these questions are broken down into essay style questions. There is advice on how to answer these as well as past exam questions. There are some simplified questions for students who will be working towards a 5-7 but then I've included some top end work. Acts covered include: - * Computer Misuse Act * Freedom of information Act * Communications Act * Data Protection Act * Creative Commons * Copyright Designs and Patents Act

Slide 2 - Introduces the learning objectives. Slide 3 - Explains the difference between client and server-side processing. Slide 4 - Talks about decision making briefly talking about the difference between performance and security. Slide 5 - Advantages of client-side processing. Slide 6 - Advantages of server-side processing. Slide 7 - Link to a video from craig and dave - computer science teachers. I do not own this content and you're not paying for it. It is an external link to a great video resource. Slide 8 - An exam style question. It has no answer sheet to this question. It's more about getting your students to apply knowledge, application and evaluation. Slide 9 - Example exam questions to support the topic. These are attached in the PDF. Made using an exam builder.

This is an assessment with answers including the structure and function of the processor. It includes: - (a) – The Arithmetic and Logic Unit; ALU, Control Unit and Registers (Program Counter; PC, Accumulator; ACC, Memory Address Register; MAR, Memory Data Register; MDR, Current Instruction Register; CIR). Buses: data, address and control: How this relates to assembly language programs. (b) – The fetch-decode-execute cycle, including its effect on registers. (c) – The factors affecting the performance of the CPU, clock speed, number of cores, cache. (d) – Von Neumann, Harvard and contemporary processor architecture.

These video tutorials will help you deliver the MicroBit lessons and will also leave some of the tasks open ended. I have uploaded one of the videos for free so that you can see what they're like. The videos in this bank include: - * Spirit Level * Simple Maze Game * Simple LED Lights * Calculator - Add two numbers together using variables * Random number generator * Controlling how an LED moves around the screen * A + B buttons (selection) * How to make crossy roads on the screen * Iteration and moving lights All include some explanation of what has been taught and the key terms needed for programming. This has been done using the blockly editor.

Objective: - We’re learning how to use data to represent characters and images. Students will be given a worksheet to start this lesson which gets them to solve what the binary says. The answer is 'computing'. Once students have solved the question using a grid, it leads you into a conversation about how computers use binary to translate messages. There is a lot of theory in this but there is a worksheet to complete at the end of the lesson and there are two worksheets to complete throughout. Where possible there have been some hints and tips written in the notes. Covered in these slides: - Character sets Exam questions worksheets Binary to ASCII conversion Explanation of ASCII and why 16 bit was need Break down of why character sets are needed Image conversion Images and pixels - how many bits Colour depth and formulas to work out file size Bits per pixel Meta data of images This resource was written by award winning teacher, Ray Chambers: National Teaching Award winner 2015 - Innovative use of technology.

This resources breaks down to students how to think abstractly. It includes answers to the questions discussed on the PowerPoint slides. It also includes a step by step guide to breaking down problems. The students will have a number of activities which require them to solve problems. There are attached videos which have been taken from YouTube resources which should help students understand how to think abstractly in more depth. I have attached a link to the OCR PDF specimen paper and I have pointed to questions relevant to this discussion. The lesson plan helps break the task up and includes answers to the PowerPoint.

This package includes 3 powerpoints that introduce object orientation to students. On top of the object orientation powerpoints, there are worksheets that help students build on the skills that they have learnt. The first activity sheet shows how to set up a class in python and how to call on it. The second shows how to pass parameters into your class using constructors. There is theory supported in the powerpoint. The third lesson shows how to design a class and is a good introduction to class diagrams.

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.

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 lesson introduces constructors to students and talks about the need for setting up the class. There is an example program to work through with a worksheet attached. it shows students how to initialise variables in their program and how to pass items in. This should help students become more confident and builds on nicely from the previous task. If students have been absent they can pick it up quite easily.

This lesson introduces students to using operators such as Add, Subtract, Multiply, Divide and Exponentiation. They're also introduced to Mod (working out the remainder) and Quotient (working out the whole number). They're given a number of activities which allow them to apply some of this and will attempt working out the median and mean. After this they're given an activity which gets them to work with the OCR structure. They're required to decompose a problem, list success criteria and build a sleep calculator. They will need to list their variables and on top of this will also need to show the development of their code. The worksheet can be typed in. All operations are explained: - num1+num2 num1-num2 num1*num2 num1/num2 num1**num2 for exponent % used to explain remainder // used to explain whole number part of division Students given extension task / independent research task for finding out the mode.

This is a 50 mark assessment to check students understanding of input, output and storage devices. As the new spec for OCR is quite new. I went through all of the computing spec to find old questions which will map into the new specification. This gives you a good idea of how your students are performing. Students will answer the questions and their is an answer sheet for you to use so that you can mark your students. I currently use the OCR A-Level grade boundaries for a rough idea.

When planning a curriculum you might want to use this sheet to help you when planning a curriculum for your school this is an example that I used for my department to help think about the curriculum.

Objective: - We’re learning to explain the benefits of using networks and to identify the different transmission media available. This scheme of work includes notes to help teachers understand the content and includes diagrams. Key things learnt throughout this lesson include: - What is the internet What is the world wide web What is a network with youtube clips to explain Different network types with videos Difference between a wan and a lan Other forms including PAN / MAN / SAN and VPN Transmission media such as UTP, FIbre optic, wireless Two worksheets with answers

This lesson does require some prior knowledge of Kodu but it gives you structure to start delivering the curriculum and it will allow you to break down each lesson and to start teaching the students different items step by step. There are opportunities for students to think about what is needed for a game. There is a worksheet to help them to start thinking about what they're going to need to include in their own game. Once you've introduced this, teach the students how to create characters, worlds, objects and how to write a simple piece of code. Students are required to use the worksheet as they work through this PowerPoint with the teacher. This is a sample lesson to get you started and can be used for KS2 or KS3.
