I have seen these theories of adult development before. I do enjoy the perspectives, but also I see a great need for them to be updated due to different societal expectations. Marriage and family are not alway a priority, and there are other definitions of family to be explored. I think that the most important thing to do with your students is ask questions to find out what their current motivation is based on thier personal life experiences. The age ranges are completely different for many students when you consider that some may serve in the military, moving the retirement of the student up considerably, but delaying family and marriage (if they desire).
