SUGGESTED TEACHING 30 GLH TOPIC CONSTRUCT ELECTRONIC AND ELECTRICAL SYSTEMS TIME SUGGESTED TEACHING AND TOPIC OUTLINE SUGGESTED RESOURCES POINTS TO NOTE HOMEWORK ACTIVITIES Unit Overview: This unit is internally sat and externally assessed in a unique form of “technology challenge” activity the context for the assessment of this unit is a six-hour (three two-hour sessions) ‘technology challenge’ this form of assessment has been adopted as it assesses a Learner’s ability to apply knowledge, make on the spot decisions and test the outcome against a challenging brief the timed and scripted activity is designed to take place within a workshop.

The unit provides learners with the opportunity to learn about the basic principles and techniques used in the construction of electronic and electrical systems this is a practical-based unit which complements the unit on engineering design (Unit F549 Level 2) and allows learners to develop further understanding of the importance of applied mathematical skills in engineering.

Learners will use their knowledge of electrical/electronic components to develop a prototype system in order to solve the selected design problem learners will present the evidence within a ‘workbook’, using a range of techniques including text, digital photography, screen dumps, freehand sketches and cad drawing.

There are many opportunities for learners to demonstrate and develop their PLT’s capabilities.

8 of 10 Engineering Diploma Sample Diploma Lesson Plan OCR Level 2 Principal Learning in Engineering H810 Unit F552: Construct electronic and electrical systems

Introduction to Reed and Tilt Switches and their use in simple circuits 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 one hour.

Learning Objectives for the Lesson

Objective 1 Learners are to become familiar with the various types of reed and tilt switches available. Objective 2 Learners are able to model a simple circuit that will detect when a window is opened. Objective 3 Learners are able to suggest a range of applications for these types of switches and suggest their possible use in other systems.

Recap of Previous Experience and Prior Knowledge

 Brief reminder of chosen circuit design software and how it functions. Refer back to work undertaken in Unit 3 F550.

Content

Time Content 2 minutes Put the class into mixed ability/gender pairs and allocate to a pre-prepared work station: NB This could be an individual Learner activity. 3 minutes Introduce the Learners to the reed and tilt switch explaining their function and operating principles – demonstrate them in action. 15 minutes Group/Individual Activity: using suitable circuit design software design a simple circuit that will detect and alert a parent when a child’s window and/or bedroom door has been opened. 15 minutes Group/Individual Activity: using prototype boards and components provided Learners are to model the circuit they have designed. 15 minutes Class Activity: each group/Learner is to explain and demonstrate their circuit to the class – class to suggest possible improvements to the circuit.
