I am developing an online course dealing with general topics and am looking to garner as much feedback as possible. We have traditionally done courses dealing with shop fundamentals, machining, etc., and are just recently getting into electrical systems. Our main audience is shop floor workers. We already have live courses in basic units, safety, and various circuits and calculations. I work with an EE who also heads a department at a local CC. He is adamant that we include a class on the NEC. I guess my question becomes, what are the most useful types of material that I can provide for this type of audience? These are short classes of about 15-20 lessons, so I can in no way, nor do I feel it appropriate, to discuss any real specific content in the Code. I do however plan to touch on how to read the book, how it is organized, why it is important and things like that. I have read your instructional forum and found many useful pieces of advice, but I was hoping that could be collected into something more specific. I know many of you teach Code classes to various levels of students, or at any rate are better versed as to what would be the bare essentials, so any feedback is greatly appreciated. Thanks.
