NAZARENE HIGH SCHOOL
SCOPE and SEQUENCE
Basic Electrical Training
Done By: Mr. Lopez
2022-2023
Introduction:
As the demand for labor-saving devices in domestic, office and commercial premises, together with automation in industrial
processes increases, the knowledge required by Electricians is becoming more involved. The Basic Electrical Technology class and
the understanding of electrical theory are aimed to provide insight and understanding of many of the technical theory concepts and
terms that every electrical person must know and understand. In addition to theoretical knowledge, the practical aspect of the work
demands that the electrician should be prepared to work in outdoor conditions and at heights and in awkward and confined spaces.
AIMS of the Syllabus
The syllabus aims to:
1. 1. Demonstrate good safety, health and environmental practices in the application of electrical theories ;
2. Apply knowledge of the units and theories associated with Electrical principles and measurements
3. Apply the theories and concepts of related calculations and experimentations in the electrical field;
4. Apply Knowledge of motors, generators and transformers and their use in power generation and distribution systems;
5. Understand the electrical codes and regulations governing electrical wiring principles
6. Demonstrate skills in the installation of wiring systems for domestic and industry purposes.
7. Display proficiency in the reading of and interpreting of electronic and electrical drawings
8. Investing the basic operating principle of electronic components in basic electronic circuits and be able to represent on
drawings
9. Produce electrical and electronic drawings to engineering standards using the principle of computer-aided design and manual
methods
10. Understand the fundamentals of the computer and its application as it relates to the Industrial Technology programme;
11. Become aware of career opportunities that exist in the field of Electrical Engineering and other related fields.
FACTORS AFFECTING SCOPE AND SEQUENCE
In developing the scope and sequence several factors were considered namely:
1. Previous Knowledge information, topics build on each other, sequence was developed after connections among electrical
concepts are established.
2. SBA Activities that need to be completed on particular topics. There are specific topics that SBA Activities must be conducted
on; this makes some topics more important than others, because these activities must be completed by a specific deadline,
some topics that would generally flow in sequence are moved to a later date because they would not affect the normal flow
of things.
3. Number of holidays during specific times of the year, and teaching time lost due to extracurricular activities, this affects how
long a particular unit will take to be completed.
