Masters Project - User preference testing

At a GLISI teacher conference held last fall, I was able to grab 12-14 people to review the competing designs. I did my best to counterbalance the presentation of the interfaces to avoid introducing bias into the results. I set up my laptop in the lobby and asked passing teachers, principals, and school board members to take a few minutes to evaluate these interfaces.

None of these users knew anything about the coaching program, so I tried to assess the ability of the interfaces to provide an overall context, to set up goals, to lead toward next steps, and to provide easy access to help. I let the users freely comment for several minutes, then I began to probe with

If you were looking for help on this page, where would you go?
Which design gives you a stronger impression of an overall structure?

These are the prototypes I showed them. The last one was the clear favorite.
