Overview
This first course, part one of a two part series, uses attention-grabbing video to provide helpful insights into automotive sources of electricity, the behavior of series, parallel and series-parallel circuits, and general electrical system diagnosis. Content is equipped with the knowledge technicians need to identify common electrical symbols in service manual schematics and use wiring diagrams during diagnosis of electrical circuit problems. 53 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 glossary of terms. 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.
