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.

Objective: - We’re learning to identify the hardware and classification linked with networks. This lesson includes notes in the teacher slides to help teachers understand the content they're delivering with links to videos and also embedded videos. During this lesson students will learn about: Client server models Client-Server Servers available Peer to peer networks Advantages and disadvantages Network hardware NIC Wireless access points Routers Switches Draw your own network diagram

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.

Introduction to Python - Assessment This task will assess students on the basics of Python. At this point the students will have only been introduced to how to use Python, comments, input, output, operators and variables. The assessment has been modified to use the OCR criteria but it should only fit into an hour. It will not require a test plan but must show evidence of testing. They're not required to show a flow chart at this point. This is a limited assessment to make sure that they can use Python. There will be further assessments which build on this in the resource bank. Use of programming techniques: • Comments • Input • Output • Operators / Arithmetic • Variables

A series of 12 slides going over questions from the A-Level computer science spec with marks that you would give students. The idea of this is that you can have a lesson where you break down the terms that the exam board would be looking for. They include the marks and show students the type of thing that would be required for an answer. This resource helped my year 12 students which is why I'm sharing it here.

This is a combination of two tasks. It helps students create a user interface. Once they have produced the user interface it allows them to get text from text boxes and write them to a text file. It has a number of procedures inside it. One produce to clear the text boxes. One procedure to save the information. Another procedure is used for going to the next record in the file. The next task in this series will allow students to move backwards and it will also allow students to delete records from the list. Comes with a complete Python file so that you can see how it works.

Lesson explaining how Data representation works. There is a PowerPoint which walks through two methods of conversion but it also specifies how to use binary. It explains to students place value and compares denary to binary. Lesson 1 in a series of 4 lessons. Students will also learn about: - Switches Binary Exam questions Binary conversion using switches Binary conversion using division Binary grid method Least / Most significant bit] Worksheet provided Content written by Ray Chambers - National Teaching Award Winner - 2015 - Innovative use of technology

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 object orientation to students and the need for classes. There is a worksheet for the students to work through and it shows them step by step how they can complete the activity. There is an example print screen in the slide show and it breaks down the need for classes in a database.

9 Slides looking at testing in computer science. Covers - Alpha Testing, Blackbox testing, Whitebox testing, Destructive testing, Acceptance testing and other test strategies. No worksheets attached.

There are 13 slides here discussing privacy concerns with the internet. The slides get students to have deeper thinking when discussing. It explains arguments for and against censorship and it gets them to also understand how the internet has made it less likely for us to hide personal information. There is some think time and discussion time build into these slides.

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.

This shows students how to design a class with a class diagram. It walks through the need to design classes and there is a worksheet attached that gets the students do design the class and build the program. They can use a number of different programming opportunities with this and it will help them for their A-level project.

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 lesson starts getting students to think about the way the world looks. Their main objectives are to learn how to create a basic landscape and to experience the techniques available. They will look at existing games and talk about what makes them more interesting. I've included some screen shots of existing games to guide the teacher. It starts getting the students to come up with a concept for their own game and they have a few ideas. Teacher requires prior knowledge of how to use the landscape tools or can use YouTube videos to support. Students to complete the worksheet to show that they're able to use the tools available and that they can come up with their idea. Homework included.

This is the final in a series of lessons which help year 11/12 use an interface for Python. It shows the final functions that delete records from a text file. It also shows them how to move to the previous record. The functions are written and the finish program is shown here with the text file needed to run it.

This is a simple worksheet that shows students how they can use object orientation with Tkinter. The idea of this program is that they can build on the knowledge in the 3 previous lessons. Example code with extension activities included.

A brief PowerPoint showing open and closed source software. There are 7 slides. They give examples of the software and contrast the two explaining the difference between proprietary software and open source software.

These 8 slides argue for and against automated decision making. The slides also comment on privacy through monitoring. We discuss items such as CCTV and also go into detail about how personal information is now being analysed.
