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

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 lesson introduces Python to the students. Throughout the lesson students will be expected to learn about: - *Sequencing *Programming *Saving *Commenting *Syntax errors This lesson is about getting them to write their first program and it is also about introducing them to the shell, printing and understanding how to use Python. They're taught how to compile, debug and the importance of coding. There are instructions for the teachers so that if they've never used Python before, they have some guidance in the PowerPoint notes. Students are required to write a story and are taught basic techniques with the print. This could provide good cross-curricular links to an English lesson. They will work through their work with the guidance of a worksheet which asks them questions about whether they have understood the key points or not.

This lesson is all about introducing data types and it teaches students about how to assign variables to sentences. They're taught to repeat these back with a work sheet which gets them to demonstrate their understanding. They're given a task where they're expected to write a story but they will need to include variables in their story. The idea of this is so that they can see how the variable appears on the screen. Part of the way through this lesson, students are invited to try out each other's stories and they should be typing in the input before the sentence appears. After this, they're introduced to different data types and they're taught about casting. This is another thing that is in the OCR spec and it's good to break each piece of the spec down piece by piece so that they can build on it.

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 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.

This lesson is about introducing the programming technique 'variables' to the students. They will also learn about assignments, and outputs on the screen which is a build on what they learnt in their previous lesson. They are taught about how to understand variables using scenarios such as buckets. There are teacher notes which will be useful for showing you how you can gather un-plugged resources. Attached with the work is a worksheet so that the students can understand how to start naming variables. They is also some questioning put into the slides which will keep the students on their toes. They are taught how to use variables, concatenation and their are plenaries that will help them to debug code with problems. This is a good way to help them spot errors in the code.

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 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.

This resource breaks down step by step, how to do fixed point binary and why it is needed. It discusses it's need for precision. It discusses the need for floating point binary and then shows examples of completing questions. Moving on from this, candidates are also taught about normalisation. Candidates are then expected to answer 6 questions in each section with an answer sheet attached at the pack. I found that there weren't many OCR resources that show how to do normalisation which is why I put this together for myself. I hope that it may be useful to others.

1.3.2 - Characteristics of networks and the importance of protocols and standards. This lesson is the first part to two lessons on section 1.3.2 of the OCR syllabus. The lesson starts off with some questioning on the CPU which was the topic I covered with students in their recent lesson. Check the PowerPoint notes. Slide break down: - Slide 1 - 4 - We’re learning to explain the characteristics of Networks and the importance of protocols and standards - Learning objective and questions. Asks students what a network is. Slide 5 - A video explaining why we need networks. Slide 6-8 - Explains what is meant by a network. Explains what a LAN and WAN is and uses key points from past computing exam papers to give students what the mark scheme would look for. Slide 9-13 - Looks at different transmission media. Gets students to understand copper and fibre optic. Slide 14 Students share what they did for homework. Slide 15 - 25 Explains topologies and includes a video. Their are unplugged activities which get the students to become the network. Final Activity included

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

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.

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

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.

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.

This bundle includes lessons on the following areas of the 9-1 computer science curriculum *Legal Issues *Computer Misuse Act *Freedom of Information Act *Communications Act *Data Protection Act *Copyright Designs and Patents Act *Creative commons *Open source / Proprietary Software *Ethical and cultural issues *Censorship and the internet *Computers in the workforce *Automated decision making *Privacy Issues *Computer technology used to analyse personal information *Artificial Intelligence

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
