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.

There are a bulk load of computer science resources here including the following topics: * Testing * Operating Systems * Lossy Vs Lossless * Logic Gates / Boolean / Karnaugh Maps * Exam questions and answers * Exam questions and answers V2 * Data structures - Tuples / Lists etc.. * Branching and Selection * Computer Science - Methodologies Some of these presentations link to my YouTube channel where I have included videos to help you deliver the content.

This lesson works on the assumption that students have already been introduced to the Arithmetic Logic unit and section (a) of the 1.1.1 spec. This lesson covers: - (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. It includes some starter exam questions around the registers and answers are included in the presentation. Students will be expected to answer these questions. There is a research based task at the end which gets them to research other factors which have an impact on the CPU performance.

Topologies Presentation includes notes to train teachers who are very new to teaching computing. Week 3 - What is topology? Objective: - •Understand the difference between LANs and WANs •Be able to give examples of each network •Identify three different network topologies. ​ Task 1 : - Make notes about the difference between a WAN and a LAN network as your teacher explains things to you. This video will also be shown: - https://vimeo.com/145979347 Task 2: - Your teacher will now get you to act out 3 different networks by getting you up out of your seats. They will follow this by watching this video: https://vimeo.com/145982596 Task 3: - As a class you will come up with success criteria and produce a poster which meets the criteria. You should comment on the following:•​LAN VS WAN •STAR / RING / BUS ​ Useful links: •https://vimeo.com/145979347 - WAN / LAN video •https://vimeo.com/145982596 - Topology video

This is the end of unit assessment for key stage 3 computing unit on networks. Students are tested on the following: - Connectivity Encryption Hardware Topologies IP Addresses Data Packets World wide web vs Internet Protocols Diagrams

Week 4 - Hardware Objective: - •Know the hardware required for developing your own network •Develop your own network using a number of different devices.​ ​Task 1 : - Discuss the different hardware which could be used on a network. Think about the devices which you would have in your house? Task 2 : - This worksheet should have been printed for you. You're required to make notes as your teacher talks about the difference in each device. Click here to download the worksheet Task 3: - Plan out your network diagram on paper and then visit www.draw.io and start producing a network diagram.

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 is a differentiated assessment which includes old national curriculum levels. You can map these to your new school levels or progress measure quite easily. I've split it into three tasks which are all slightly different. You may use these in any way you like. The idea is that they create a quiz. Some students who are on the red task will need to make sure that they go and try some research in order to understand how a binary search would work in Python. This is why it's a higher level. Students will need to be independent on some of these tasks. I found this useful for my own teaching and it meant that the students who were lower at coding could try the lower task. In terms of challenging students, if I knew that students of higher ability would try and pick the lower tasks, I would allocate them myself. Green (easy) Amber/Orange (medium) Red (hardest) Feel free to modify.

These Python videos will introduce you to the basics of Python 3.3 and will get you started by building lists, reading text, writing text, using strings, using floats, using integers and it will show you how to do conditions using IF. The videos will get you started and can be used by your students to introduce new features. All videos are encoded using MP4 / MPEG 4 List of videos: - *Writing Text *Reading Text *Multiple Lists / Arrays *Single Lists *Conditional / IF Statements *Introductory video *Int / Float / String

A nice little resource made to start people on coding. It introduces common mistakes with coding and also gives them 6 activities to attempt. They have been written based on difficulty for example, it goes from green to red. Activities on this are basic string manipulation but it will be a good first lesson for students to get a taste of Python. Includes inputs, outputs and string manipulation.

This lesson requires prior knowledge of Kodu and gets you thinking about paths. It introduces the path feature to them and you give your students 'tinker' time so that they can explore the tools more. Get the students to think about how they move characters in the game. Introduce automatic movement and show them how to follow other objects. Students complete the worksheet.

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 lesson will show students how they can use the following techniques with pseudo code. Arrays Concatenation Substring Variables Upper Lower Multidimensional Array There is a worksheet attached with answers and it should give them two lessons to try different code. I hope that this is useful for computer science students

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.

This is a powerpoint which you can get part of a pack. It teaches you how to do a multidimensional array and shows examples of how they can be used to work out the range. Hope that it is useful to some other teachers.

A year 11 Pseudo Code cheat sheet that shows the candidate how to write a program that uses concatination and it also shows the client how they can do file handling, file writing and how they can append files. It might be a useful print out for candidates to have when learning to write code.

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 is a tool for management or staff to use in the school for recording e-safety incidents. Many schools use CPOMS or other behaviour management tools. Unfortunately some schools do not have the money to buy more and more software to store their e-safety incidents. This is a macro based excel tool which allows schools to record any incidents. It is simple to use and you can use filters on the second page to look at the date it was recorded or updated.

Objective: - We’re learning to identify different network infrastructures and the encryption involved. During this lesson there are some videos to break up the lesson and teaching notes for you to have a look at. On top of this there are some activities for them to try such as creating their own encryption key. This usually makes the lesson more engaging for the students. Content covered in this lesson: - Topologies Ring Star Bus Mesh Students to draw the network topologies and explain the advantages and disadvantages. Wifi and wifi channels Encryption using the Caesar shift and also comments on brute force. Public and private keys used in encryption.

I have given this task out to some of my sixth form students in the past. It gives them 10 days of challenges. I usually give it out on the 15th and get them to explore their OOP programming using these challenges. This includes an answer sheet.
