Learning Objectives

Indicator: 3.5.1.LI.10 - Demonstrate Knowledge and understanding of Appliance Servicing. Describe the process of servicing electrical appliances.

By the end of the lesson, learners can:

Identify common household electrical appliances and describe the function and operation of each, including irons, kettles, and blenders.
Distinguish between a faulty and a functioning electrical appliance by observing key signs and symptoms.
Outline the step-by-step process for testing an electrical appliance to diagnose a fault.
Explain the appropriate remedy for each diagnosed fault and describe how to carry out the repair safely.
Work collaboratively in mixed-ability, gender-inclusive groups to diagnose and report on a faulty appliance, demonstrating honesty and sincerity in their findings.

content standard text - p.184: 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 appliance maintenance.
1. Types of Gadget/Circuit to be Diagnosed
2. Differences between faulty and functioning electrical Appliances
3. Outline steps in testing appliance for fault
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 gadget/circuit to be diagnosed and describe its operation and function e.g., Iron, kettle and blender.
2. Distinguish between a faulty appliance/circuit and a functioning one teaching learners to be honest and sincere in their diagnosis.
3. Describe how to test each appliance/circuit to diagnose 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.10). 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.
