This lesson is close to the end of the unit of work on data presentation but can be run as a standalone lesson. In this lesson students are introduced to different types of compression and investigate the reasons why files need to be compressed for efficient computer use. 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 a stand alone lesson that introduces students to the concept of hexadecimal and asks them to develop skills in converting between binary and denary and hexadecimal. Students will require knowledge of and skills with converting between binary and denary. It also starts to introduce the idea of colour and images being represented by computer code. It touches on high and low level programming languages. 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 forms part of a unit of work that enables students to understand how text, images and sound are stored and edited on a computer. This lesson focuses on sound recordings and asks students to understand how a digital sound recording can never be as high quality as original sound, and tests them on how the sound recording can be improved in quality. 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 4th in a series of lessons designed to improve students’ understanding of how networks are organised. In this lesson students develop their understanding of key vocabulary such as IP addresses and the role of the router in transferring data between computers. It involves recall of key information from lesson 2 in the unit. Students are asked to describe the handshake process, discuss the format of data packets, and consider possible errors in transmission of data. 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. A homework task is also included in this lesson.

This lesson is the 5th in a series of lessons designed to improve students’ understanding of how networks are organised. In this lesson students consider a range of different features of wired and wireless networks and how they impact on the performance of the network. Students should be taught to be critical about real life situations and apply their learning in this lesson to explain which type of network is best for which type of situation. 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 is the second in a sequence of lessons that introduce students to the principles of network organisation and the reasons why networks are used. This lesson looks at the differences between LAN and WAN, introduces the idea of a PAN, and also considers the role of the router in creating a LAN. The lesson plan is provided in PPTX, PPTS and PPT format, although some image and animation settings lose functionality in the older version of PowerPoint. The learning mat (worksheet) is also available as a PDF version. This will print on A3 paper.

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.

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 is a busy lesson and is fourth in a sequence of lessons that consider how computer systems integrate hardware and software. In this lesson, students consider what happens in the CPU during the fetch-decode-execute process. This lesson may need to be differentiated for some classes. There is an opportunity to consider how the registers work using the little man computer model using an online model. The lesson plan is provided in PPTX, PPTS and PPT format although some functionality (such as the video screen grab) is lost in PPT format so the screen grab is also provided separately. The worksheet (learning mat) is provided in PPTX, PPT and PDF formats.

This lesson is the 11th in a sequence of lessons that looks at how hardware and software are integrated on a computer system. This lesson looks at the differences between high and low level programming languages that can be used to create software. The lesson plan is provided in PPTX, PPTS and PPT formats, while the learning mat is available as PDF, PPTX and PPT files. Learning objective: Understand the characteristics and purposes of high and low level programming languages.
