Brief, seven to ten minute, e-learning training units will provide apprentices with basic knowledge of the concepts outlined in Table 2. These units will include text, brief video clips, and interactive on-screen slides that guide apprentices through content with brief quizzes that assure understanding [31, 34, 35]. Units are being developed with Captivate (Adobe Systems Incorporated, San Jose, CA) software [13]. Members of the research team have developed similar ergonomics training programs and taught ergonomics with e-learning [36, 37]. Apprentices will be reminded to complete home units by a text message or email in the week prior to onsite training.
