Hi Terry,
You raise a very good point about student motivation. The majority of my students are full time workers and I have them in class from 4 until 10 pm. This presents a real motivation challenge.
For some of my classes I have the students bring examples from their community lives of how the content can be applied. I also assign them some assignments where they apply content either in their homes or community so they can see the value of what they are learning and this really helps with motivation as well. So they get to see application and relevancy in both their professional and private lives.
