Certainly my request, as with all training videos, it that the very first module is a thorough review and explanation of the user interface. In the military they call this stage 'naming the parts'. It is a necessary preamble to all subsequent explanation and means that you can repeatedly and easily refer back to a single point of reference whenever something is mentioned, the name or use of which has escaped your memory. I know it is difficult but when the module designer is as familiar with his subject as he must be to do the training, it is incredibly difficult not to make unconscious assumptions about the trainee viewers state of knowledge. With an initial'naming the parts' module it is possible to employ a newbie to review the content just to discover what questions they need to ask to gain a thorough understanding of the interface.
