Changes to the curriculum for 2021:

• The curriculum has been revised and changed. • Many sec ons have been removed. • All Learning Outcomes have been renumbered and rewri en.

Modules and weigh ngs:

The new curriculum has been broken down into Modules with weigh ngs as follows:

New curriculum (2021):

Module 1 Safety precau ons 10%

Module 2 Fire and fi re fi gh ng 5%

Module 3 Hand and power tools 5%

Module 4 Direct current theory 30%

Module 5 Conductors and insula ng materials 5%

Module 6 Wiring of premises 25%

Module 7 Tes ng of a single phase installa on 5%

Module 8 Magne sm and electromagne sm 10%

Module 9 Renewable energies 5%

Overview of changes

• Old Module 1 – Safety and basic hand tools - has now been broken up into 3 modules: – M1 Safety precau ons, M2 Fire and fi refi gh ng and M3: Hand and power tools – Safety precau ons now include new Learning Outcomes on the Occupa onal Health and Safety

Act and accident and incidents and more detailed Learning Outcomes on housekeeping, safety signage and fi re. – Grinding wheels and environmental prac ce are no longer specifi cally men oned in the curriculum. – ‘Hickey’ has been added to the list of basic hand tools that students need to know how to use and care for. – Learning Outcomes have been added on the care, maintenance and safe use of power tools.

TVET FIRST

• Electrical circuits (now called DC circuit theory) now accounts for 30% of the curriculum compared to 12% previously. • Fleming’s le -hand rule is no longer covered under magne sm. • Transformers have been completely removed from the N1 curriculum. • Ba eries are now part of the direct current theory module and covered in far less detail than before (only the diff erence between primary and secondary cells is required). • Direct current sources have been removed completely (Fleming’s right-hand rule, opera on of a DC generator, other means of producing electricity). • The alterna ng current sec on has been reduced to cover only Faraday’s laws of electromagne c induc on and the genera on of a sine wave. • Measuring instruments have been removed. • Cables and wire ways have been removed. • Wiring of premises is now weighted 25%, up from 18%. • Iden fying electric components and drawing wiring diagrams for fi xed, sta onary and portable appliances has been removed. • The func on of the following protec ve devices is now required: circuit breaker, earth leakage relay, ligh ng arrestor, fuse – but students are no longer required to describe the principle of opera on of single phase circuit breakers, three-phase circuit breakers and core balance earth leakage relays.

Load distribu on and energy control units are no longer covered. • Tes ng of earth leakage relays and motors has been removed. • Electronics has been removed. • A new module on renewable energy has been added – this introduces content on renewable energy for the fi rst me in the TVET curriculum.
