Learners may complete a number of individual assignments, which together cover the assessment criteria, or one larger integrated assignment that addresses all assessment criteria. This unit introduces learners to some of the skills and related theory required to design, construct, install, repair, service and generally maintain a wide variety of electronic circuit and control systems. It provides learners with the opportunity to investigate components, simple electronic circuits and devices in order to construct and test simple circuits. With appropriate planning it is possible to utilise a circuit board manufactured in unit f543 to complete fully working circuits in A practical unit with many opportunities for learners to develop and demonstrate a number of PLT’s. = Innovative teaching idea Engineering Diploma = ICT opportunity 3 of 11 Sample Diploma Scheme of Work OCR Level 1 Principal Learning in Engineering H809 Unit F546

OCR recognises that the teaching of this qualification above will vary greatly from school to school and from teacher to teacher. With that in mind this lesson plan is offered, as a possible approach but will be subject to modifications by the individual teacher. Lesson length is assumed to be two hours. Learning Objectives for the Lesson Objective 1 Learners are to become familiar with the various types of visual and audio feedback devices Objective 2 Learners are able to model a simple circuit that will detect when a fish is caught Objective 3 Learners are able to suggest a range of applications for these types of feedback devices and suggest their possible use in other systems Recap – brief reminder of chosen circuit design software and how it functions. Refer back to work done in unit F550. 10 of 11 Engineering Diploma Sample Diploma Lesson Plan Content Time Content 2 minutes Put the class into pairs (mixed ability/gender) and allocate to a pre-prepared work station: N.B. This could also be an individual student activity. 3 minutes Introduce the Learners to the various feedback devices available explaining their function and operating principles. 15 minutes Group Activity - using crocodile clips (or other suitable CAD circuit design software) Learners are to design a simple circuit that will detect when a fish has taken the bait and alert the fisherman to the fact – Learners than print off a copy of their circuit design. 15 minutes Group Activity – using the prototype boards and components provided Learners are to model the circuit they have designed. 15 minutes Class Activity: each group is asked to explain and demonstrate their circuit – where there are problems the class suggest improvements/solutions. 5 minutes Group Activity – using advice given Learners are to modify their CAD circuit design and prototype circuit Consolidation Time Content 5 minutes Group Activity – Learners are to photograph their circuit and glue this into their workbook along with their circuit design. Homework Make notes on their photographed circuit Produce a PCB of circuit for next lesson. Next lesson. Construct the circuit. Engineering Diploma 11 of 11
