This lesson is the 8th in a sequence of lessons that cover topic 3: computing of the Pearson Edexcel GCSE Computer Science course. In this lesson, students investigate the role of the operating system software in a computer system. By the end of the lesson they should be able to list examples of operating systems, state or describe the functions of an operating system and explain how the operating system manages the CPU in scheduling actions. There is a significant amount of key vocabulary important for this lesson. The lesson plan is provided in PPTX, PPTS and PPT formats, while the learning mat is available as PDF, PPTX and PPT files. Note that some animation features are lost in the PPT formatted files. The lesson includes a ‘bingo’ bell work starter activity. The learning mat is designed to be printed in A3.

This lesson is an introduction to a third unit of work that challenges students to consider the hardware and software on a computer system and how they interact. The unit will follow the GCSE specification for Pearson Edexcel Computer Science, but each lesson can stand independently. In this lesson, students must identify and describe a range of peripherals, and explain the difference between hardware and software. This lesson is suitable for key stage 3 and key stage 4. The teacher’s notes would enable a non-specialist to lead the lesson. It is suitable as a cover lesson to preempt delivery of the more detailed lessons in future. The lesson plan is provided in PPTX, PPT and PPS format. The accompanying learning mat is provided in PPT, PPX and PDF formats.

This is the first lesson in a sequence of lessons considering the basics of data representation and binary mathematics. This lesson introduces students to the reasons why computer scientists need to understand and use binary mathematics and introduces the terms kibibyte, mebibyte and so on. There is a fully detailed lesson plan with reading, writing, communication and maths links and careers guidance links are also highlighted. There is an accompanying learning mat or worksheet for students to complete. Learning Mat (LM) Worksheet is supplied as PPT, PPTX and PDF formats.

This lesson is the 3rd in a series of lessons designed to improve students’ understanding of how networks are organised. This is a ‘back to basics’ lesson that challenges students to use technical language about the internet and world wide web accurately. It also covers basic understanding of the role of the router, what a browser is, distinguishing it from a search engine. Additionally this lesson covers information about connection cables needed for the BTEC Digital Information Technology course. This lesson is provided in PPTX, PPTS, PPT formats. The learning mat is provided in PPTX, PPT and PDF formats. Some animation and image features may be lost in PPT formats.

This lesson is the 10th in a sequence of lessons that looks at how hardware and software are integrated on a computer system. This lesson looks at the reasons why computer programmers must make sure that their programs can cope with errors and the ways that they do this. There is a significant amount of new key vocabulary in this lesson, and it would be a good idea to set a homework that asks students to reinforce the terms introduced in this lesson. The lesson plan is provided in PPTX, PPTS and PPT formats, while the learning mat is available as PDF, PPTX and PPT files.

This is the sixth lesson in a sequence of lessons that cover Topic 3: Computers on the Pearson Edexcel GCSE Computer Science course. In this lesson students are reminded about the core model for a computer system, and discuss the need for secondary storage. They are introduced to the history of the development of secondary storage and are asked to compare the functionality, use and benefits and drawbacks of optical, magnetic and solid state storage. Lesson plans are saved in PPTX, PPTS and PPT format. The learning mat (worksheet) and starter activity are saved in PPTX, PPTS and PDF format. Note that PPT files have lost some of the functionality of the animation settings and images.

This lesson builds on learning from previous lessons related to binary numbers and binary arithmetic. In this lesson, students will consider how a computer can manipulate binary numbers and multiply or divide by powers of 2. This is a skill required for the Edexcel GCSE Computer Science course but the lesson can be adapted for other groups or courses. Learning Mat (LM) Worksheet is supplied as PPT, PPTX and PDF formats. Lesson Plan (LP) is supplied as PPT, PPTX and PPT Slideshow. Note that PPT files may lose some functionality.

This lesson is the fourth in a sequence of lessons on the topic of data representation. In this lesson students are introduced to the rules surrounding binary addition. There is a learning mat with questions of increasing difficulty. At the end of the lesson, the students are introduced to the idea of an overflow error. Learning Mat (LM) Worksheet is supplied as PPT, PPTX and PDF formats. Lesson Plan (LP) is supplied as PPT, PPTX and PPT Slideshow. Note that PPT files may lose some functionality.

This lesson is the sixth in a series of lessons on data representation and builds on lesson 5 to look at how computers process negative numbers. There are significant links with maths in this lesson and students need to be clear that adding a negative number is the same as subtracting the positive number. The teacher notes demonstrate two different ways to find the two’s complement of a binary number. The worksheet (learning mat) includes exercises to test students understanding of both processes. Learning Mat (LM) Worksheet is supplied as PPT, PPTX and PDF formats. Lesson Plan (LP) is supplied as PPT, PPTX and PPT Slideshow. Note that PPT files may lose some functionality.

This lesson builds on the first lesson about Morse Code, and challenges students to think about the reason why encryption is needed and then asks them to use a Caesar Cipher to code and decode secret messages.

This is the fourth lesson in a sequence of lessons about encryption and cipher techniques. The pig pen cipher is a technique mainly developed by freemasons to code messages to each other. Students will investigate how the technique works and reflect on its effectiveness.

This lesson is the penultimate lesson of a unit about data representation, file sizes and compression. In this lesson, students are introduced to ways of measuring file sizes and asked to familiarise themselves with the terms of measurement as well as convert between them. Ultimately, they should be able to write an expression to show the calculation needed to work out the size of a sound or image file. Learning Objective: To understand that data storage is measured in binary multiples. And to be able to construct expressions that calculate file sizes and data capacity requirements. Learning Mat (LM) Worksheet is supplied as PPT, PPTX and PDF formats. Lesson Plan (LP) is supplied as PPT, PPTX and PPT Slideshow. Note that PPT files may lose some functionality.

This lesson is the first of a sequence of lessons that challenge students to consider how plain English can be coded or ciphered. It builds on understanding of what Morse Code is used for and students have to cipher and decipher messages themselves. it is an introduction to a unit of work on ciphers and encryption.

This lesson draws the whole unit of work on Data Representation to a close. Start with providing students the opportunity to complete the assessment task under test conditions then when work is marked, use the lesson plan (LP) is an opportunity for Dedicated Improvement and Reflection Time (DIRT). Students will understand the correct answers to the questions on the assessment, and then complete 3 targets set by the teacher in their feedback. There is a marksheet (XLSX) to record student scores and to analyse class performance. Learning Mat (LM) Worksheet is supplied as PPT, PPTX and PDF formats. Lesson Plan (LP) is supplied as PPT, PPTX and PPT Slideshow. Note that PPT files may lose some functionality.

This lesson is the fifth in a sequence of lessons and looks at processor performance when related to clock speed, number of cores and bus speed. There are a variety of activities, but the main demonstrate phase considers the language of exams and helps students to understand how much to write in exam style questions. The learning mat (worksheet) is provided in PPTX, PPT and PDF formats. The lesson plan is provided in PPTX, PPTS, PPT formats, though the user should note that some animation and image features lose some functionality in PPT format.
