New Course Notification - Suspended Scaffolding Safety

Overview
With more than 10,000 scaffold-related injuries reported each year, OSHA mandates worker training. This program helps the learner understand the dangers of working with scaffolds, and how these risks can be minimized by knowing the correct ways to erect, maintain and use scaffolding equipment. 57 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.
