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 lesson builds on learning from the introductory lesson for this unit. In the previous lesson, students were asked to complete a homework research activity, so if you have not run this lesson you will need to delete or change this activity. The content of this lesson is a core part of the learning for the GCSE computer science course and asks students to understand that while the computer is running a program, the data and instructions need to be stored / held. You can extend students to understand that this disappears when the program stops or the computer is switched off. This lesson has been created with the Pearson Edexcel specification in mind, but is appropriate for other exam boards. Lesson plans are provided in PPTX, PPT and PPS format, while learning mats are provided in PPTX, PPT and PDF formats.

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 the second lesson in a sequence of lessons about modern use of technology. Students will be given the opportunity to build on learning from lesson 1 and to consider in greater detail the issues surrounding the use of open networks and mobile internet access. In this lesson, students will develop understanding of reasons why some networks are more secure than others, and be able to describe the impact on performance of ad hoc networks of distance, amount of data traffic and type of device. The lesson plan (LP) and learning mat (LM) are provided as PPTX, PPT and PDF formats, although animation and other features are limited in PPT and PDF formats.

The third lesson in a sequence of lessons that consider use of modern technology by businesses and individuals. This lesson builds on learning about ad hoc networks and focuses on mobile network coverage and the reasons why people do not or cannot access the internet. The lesson leads a discussion about network availability (rural versus city locations, developed versus developing countries, available infrastructure, mobile network coverage as well as issues surrounding the digital divide. The main task is to write a newspaper article about these issues and factors.

This is the fifth lesson in a sequence of lessons that consider how business organisations use modern technology to improve their working practice. In this lesson students clarify the difference between cloud storage and cloud computing, learn about the different tools and features in cloud computing applications and discuss the benefits of collaborative working using cloud computing tools. The practical activity that is planned for in this lesson asks students to create a tutorial / user manual for a student entering their school on how to use any VLE or cloud computing softtware that you use in school. The lesson plan and learning mat are provided in PPTX, PPT and PDF formats although animation settings are altered in older PPT software.

This is the 7th lesson in a sequence of lessons covering Topic 3: computers of the Pearson Edexcel GCSE Computer Science (2020) course.

The lesson plan is saved as PPTX, PPT and PPTS formats. Note that some features are lost in PPT formats.

This is the assessment related to the unit of work on encryption. There is an associated DIRT lesson that follows the assessment and a tracker to check class achievement. Grades are related to approximate achievement expected by a year 7 group and should be amended or differentiated for other year groups. The assessment includes practical decryption activities, multiple choice questions and explain/describe questions as well as state / identify questions.

The fifth lesson in a sequence of lessons that challenge students to think about different ways that plain text can be converted, encrypted or coded into cipher text. This lesson introduces the Playfair cipher. This is a more challenging lesson to think about than the previous lessons and may need to be significantly differentiated for younger or students with additional educational needs.

This lesson draws together the learning from the previous 5 lessons and looks at encryption in practice and for data that is transmitted via the internet. It includes an opportunity to clarify the difference between the internet and the www. It looks at the purpose of encryption and focusses on key terminology related to this aspect of algorithm and computational thinking.

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.
