Dear Sue Sugizaki,
Ive been following this thread quite a time now.
When you quoted an instance that they have no idea what an word icon in the editor means, In my opinion there's a considerable learning curve involved for your colleagues not only with respect to moodle, but with the General computing lingo itself.
Phase 1: This is an excellent opportunity to bring in a Blended learning approach starting from Basics (what would be classified as basics will depend on the current state of your colleagues when it comes to using a computer).
Phase 2: Once they get to know some basics i would suggest mapping your business logic with automation using computing principles ie., theory/ongoing practice to system mapping to bring in a system orientation.
(Say for example you have something like discussion board in your office where all employees can write their own views, questions if any after attending each of their training sessions, And any other employee who has a clear view about the subject can write a response in the board [if you are wondering why would a company have such a thing called discussion board, its an excellent strategy to bring in a collective learning and grow as a team]
you can first convey to them that this practice when taken online has its own advantages [because they might not be ready to learn a new conventions and practice it if theres not something new and advanced which can make their life easier than using the old/existing practices]
like people can have
1. Flexible timings to post a question or respond to it in that way they can still finish their deliverables and update themselves by asking or replying/helping others to understand
2. Can become a data bank in which the same question asked by a person last year may not reoccur or wait for an answer the next year from a different person, he can perform a search through the databank to get to know more better
3. Peoples contribution and knowledge may stay even after they left the organization helping others to understand and grow. ....etc etc etc )
Phase 3: After highlighting all your business practices with system orientation you have set the perfect platform for people to accept a change, and now go ahead with moodle.
Start with how one single platform - moodle can collaboratively perform all intended functionalities, and then how does it maintains privacy of your data(by using authentication and authorization mechanisms) and go into specifics which might be suitable for your type of business.
Phase 4: Now that you have explained everything and provided a understanding that why they should go ahead with moodle, let them explore things for themselves and get exited.
So providing a track learning(by designing a course/curriculum) in a manner they explore and find out things to learn more and more, the more they explore the more they learn kind of, and finally getting to see their progress.
Voila you have educated your colleagues on moodle, actually more than that
Let me know if this helped, and also if something pops up in between.
