Learning Objectives

Indicator: 3.5.1.LI.11 - Describe the process of servicing electrical wiring circuits

By the end of the lesson, learners can:

Identify and name the common types of electrical wiring circuits found in homes and workplaces, such as lamp circuits, socket outlet circuits, and fan circuits.
Describe the common types of faults that occur in electrical wiring circuits, including open circuits, short circuits, and earth faults.
Outline the step-by-step procedure for testing an electrical circuit to locate a fault, using the correct testing instruments.
Explain how to solve identified circuit faults by applying appropriate corrective measures.
Work collaboratively in mixed-ability groups to diagnose a given circuit fault and present their findings orally and in writing.

content standard text - p.185: the front page prints "Strand 4." for Electrical and Electronic Technology inside the YEAR THREE section, where Year 3's strand 4 is Wood Technology (printed pp.164 and 170); the Contents page (printed p.6) prints "STRAND 5. ELECTRICAL AND ELECTRONIC TECHNOLOGY" for Year 3 and Year 2 numbers the same strand 5, so the row is filed under strand 5

Exemplars (from the NaCCA curriculum)

Focal Area: Processes involved in an electrical circuit.
1. Identification of types of Circuit eg lamp, socket outlet,or fan circuit
2. Identify nature of fault
3. Outline steps in testing the circuit
Pedagogy:
Research and Collaboration: Organise the learners into mixed ability and gender inclusive groups and task them to undertake the following practical activities:
1. Identify the type of /circuit to be diagnosed a
2. Identify nature of fault.
3. Outline steps in testing for the fault
4. Explain how to solve the problem. NB: Ensure all learners participate in all varieties of practical activities and project work given when practical wiring is being carried out, girls and the physically challenged should not be left out. If possible, some of them should be made group leaders learners who may be physically challenged should be given enough time to complete their project work.

Assessment (3.5.1.AS.11). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall; Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning; Level 4 Extended critical thinking and reasoning.
