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.

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 activity will teach you how to develop a simple table using Python and Tkinter. It walks you through step by step, how to add records to a database. It shows you how to create the table and how you can insert information into the table. It shows you how to make a navigate button that moves forward through the records in the database. This guide is 7 pages long and includes the full code for the activity with explanations. Useful to anyone doing classes for the first time with databases and Tkinter. It shows you how to make the user interface.

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.

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 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.

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.

These are 4 programming challenges which include the following programming techniques. You can get the students to work through these tasks and evidence the work. I get my students to show print screens and testing for each of these tasks and then they can use the tasks combined to make their own program. *While Loops *Variables *Input *Output *Lists *For Loops *String Manipulation

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.

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 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.

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 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 is a short presentation which explains to pupils how to compare lossy with lossless. There are some examples. There are 9 slides and there are some examples of how lossy vs lossless is used with a dictionary to compress text.

This presentation introduces operating systems to AS Level Computer Science. Also includes a YouTube link to a video of the teacher presenting this lesson online. Students can have access to this video to re-cap on the lesson afterwards. It covers the following areas *What is an operating system *Functions of an operating system *File management *Device management *Memory management *Process management *Network management *User management *User interface Types of operating system *Distributed *Embedded *Multi-Tasking *Multi-User *Real-Time *Exam Tip

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.

Over 30 exam questions with PowerPoint slides and answers for the teacher to work through for the Computer Systems part of the OCR AS Level Computer Science exam. These are past questions and the answers have been broken down into smaller parts to help students answer it. You can email these to your students alternatively you can go through the answers with your pupils. There are questions on the following topics within these slides: - Database Ethics Data transmission Handshake DBMS RISC/CISC Client Server Model HTML CSS SQL Binary / Unsigned Binary RAM/ROM Network Models Real-time

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.
