Designed to provide direct support for the revised GCSE Key Stage 4 Technology syllabuses, this series has been prepared by a team of NEAB examiners. Each book contains a mixture of extended projects, tasks and activities, together with written-paper key points and sample questions. Coverage of appropriate knowledge and understanding is integrated into a project structure, so that pupils prepare themselves for the written paper as they tackle the coursework. Alternatively, sections of the books can be used as a general resource to support any project. The linked television series emphasises industrial design and manufacturing practices, the application of systems and control, and the use of IT. Each programme is intended as a general introduction to these aspects of the National Curriculum within the context of the examination syllabus. After an introductory project guide, providing prompts and checklists to ensure coverage of the investigation, development, testing, evaluation and presentation of design proposals, this book offers four projects for electronic products. The first involves designing and making a digital lock, the second an electronic timing device for use in a dentist's surgery, the third an alarm for a production company, and the fourth an electronic toy or game for a young child.
