Students will understand the correct answers to the questions on the assessment, and then complete 3 targets set by the teacher in their feedback. The lesson plan is provided in .PPT, .PPTS and .PPTX format, while the learning mat or assessment sheet is provided as PPTX, PPS and PDF.

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.

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 introduces students to different devices that are computer controlled, and defines the term ‘embedded processor’. There are a range of activities that allow students to compare embedded and general purpose computer systems, and investigate the hardware used. This lesson includes a ‘matching pairs’ card game for the bell work activity. Learning mat and starter activity are provided as PDF, PPTX and PPT format. The lesson plan is saved as PPTX, PPT and PPTS formats. Note that some features are lost in PPT formats.

This lesson builds on lesson 6 in this unit, and describes the difference between symmetric and asymmetric encryption. The lesson includes the full cycle of activities and includes recall activities such as brain dump, and assessment for learning strategies such as a hinge question.

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.

This is the third lesson in a series of lessons about ciphers and encryption. In this lesson, students consider why a simple cipher such as the Caesar cipher is inappropriate for internet encryption and look at a more complex cipher method. They are also introduced to the world of code breakers during World War II and the work of Alan Turing.

This lesson is the third in a sequence of lessons that introduces students to look at how data is stored and manipulated on a computer system.
