If you are teaching software, use a simulation program to SHOW and DEMO how to use the program. The instructional design philosophy I adhere to is to explain WHY folks need to know it and how it will make their work easier. Then SHOW them and how to do it and then have THEM actually do the steps to learn the program. Use a program such as Macromedia's captivate or or Camtasia Studio and you will be good to go. The nice thing is now you can create flash enabled SCORM Compliant modules for Moodle. Looks more professional and certainly will be a helluva lot more interesting than "reading" and online manual to learn the software...DEMONSTRATE IT and sell the idea of why to learn it to get buyin. Otherwise you will still have such difficulties...
