 I think we're in the process of moving from an educational model that's designed for a much smaller number of students to a much broader population of those attending university and when you add on to that the enormous changes that technology has brought to education, to the way we communicate, to the way we access information, I think that's very much a transition phase that we're still moving through. So I think universities will still award credentials like degrees but what I do think we'll see is a much broader range of ways that students can demonstrate competency in a subject to actually earn those credits. I'm going to go for when we can routinely incorporate adaptive learning practices into course designs so the ability to really adapt and personalize the educational experience for students. I think if we realize that over the next 30 years or so that really will influence how teaching moves forward. I think some of the major issues that will face education in 2050 are actually quite similar to issues that we face right now so the equity of access to educational opportunities is currently an issue. Online learning is expanding possibilities for many people but I think this will still be an issue in 2050.
