Overview
This course brings must-know electrical concepts and HVAC service procedures to life! An excellent way to introduce essential electrical topics, from basic concepts of electricity through motors and controls, part two of a three part series takes a look at fundamental principles of alternating current and power distribution in action, familiarizes viewers with five types of motors, and explains the use of relays in HVAC systems. 54 interactions actively involve the learner in the training. Lesson interactions provide the learner opportunities to apply what he or she has learned. The computer assesses the learner's level of understanding of all learning objectives. When the learner answers a question incorrectly the computer provides remedial instruction and reviews the material until the learner can answer correctly. All questions in this course are fully narrated. Narrations enhance comprehension and are welcome support for learners with reading skill deficits and when English is the learner's second language.
Mastery's exclusive Follow-up Review, standard in all Mastery Advantage courses, provides time-delayed reinforcement and review of the learner's newly acquired knowledge. The Follow-up Review enhances the transfer of newly acquired knowledge to the learner's long-term memory.
The Learner navigates through the course and its resources using the standard Mastery Control Bar. Course resources include a fully narrated glossary of terms. Each term is pronounced and its definition read aloud to the learner. A topical index provides a complete map to the instructional material. The learner can ask for all course information on any topic at any time during the lesson presentations.
