Hi Ann,
Good way to make your course content "real". As for the guest speakers, this is what I call the "parent syndrome". Parents are suppose to tell us certain things and we kids dismiss it somewhat because it is their job to tell us these things. This is the same for instructors. I have taken my students on field trips and had guest speakers come in. After the speakers leave the students talk about how the speakers made everything so real. Then they say, "why don't you ever tell us those things?". I just covered that very same topic… >>>
