The Future of Higher Ed

I think I'm going to start a new series of blog posts relating to a subject that's important to me - the future of higher education. We spend a lot of time at work talking about the state of higher education and how it is changing as we enter the 21st century. There are tons of people online giving their two cents - I figure I'll start keeping track of people whose opinions I like or don't like.

Its worth noting that a number of people are worried that higher education is at risk of becoming a bursting bubble, like real estate or internet stocks. The rationale is that students are vastly overpaying for degrees that don't guarantee them middle class wages, and that sooner or later these people are going to start defaulting on their loans or stop coming to college or start looking for alternatives to college education. The other fear is that universities are the next newspaper industry in that they are not adapting fast enough to the changing realities of the world. Sooner or later some disrupting technology will revolutionize how students become educated and many traditional universities will become obsolete basically overnight.

My personal opinion fluctuates, often depending on what kind of a day I have at work. Universities are full of bright engaged faculty who have students best wishes in mind and who work hard to provide a quality education. On the flip side, universities are also giant bureaucracies which often react slowly or poorly to change. Tenured faculty often act in their self interest to protect the status quo, and there is very little means to realistically incentivize bad or ineffective tenured instructors to adapt. Then there's the problem of leadership... its hard to get effective leaders, particularly at mid-level universities where administrators often come to burnish their credentials in the hopes of landing a bigger job in a few years.

Well, there are a host of other issues - I guess I can talk about them in due course.

Here is a brief list of some links I've been enjoying recently on this topic.

  • David Brooks at the NYTimes (paywalled content) thinks that universities should let MOOCs and other internet-based sources provide technical content, while the university itself should focus on practical content. Practical content is things like solving problems, critiquing designs, discussing ideas, etc. I think he's right on the money.
  • Minerva University is a new for-profit university being started by Snapfish founder Ben Nelson. Instead of trying to get existing universities to adapt, Minerva is building the university of the future from the ground up. I like a lot of what I see on the website, including a focus on using the internet to deliver lectures, followed by practical hands-on training in class. Instead of tenure they are offering renewable three year contracts. This is almost certainly going to be the wave of the future in many universities, whether faculty like it or not. One important point: Minerva is trying to be as good as an Ivy League school. To some extent, you can expect an enterprise like this to succeed because to a large extent its easy to teach excellent students. I think a much more relevant and challenging problem is how the university of the future will educate the mid-tier students.
  • Mark Cuban advises students to pick a university based on whether it'll still be in business before you graduate. It's a bit hyperbolic but his point is well taken. He relates universities to the newspaper industry and wonders what the business model will be like in a few years time.
What would the ideal university of the future look like? How much would it cost? Who would teach? Who would attend? What would be the role of research? of faculty scholarship? of tenure? The only thing I'm sure about is that whatever it is, it won't resemble much of what you see today in higher ed.

Bionic Eyes

Looks like I might have to be eating my words on bionic vision. I've been pretty skeptical on the clinical promise of prosthetic vision systems owing to my time spent in that field during my time as a postdoc. I've always thought the concept was really cool but the technical limitations just too insurmountable to provide meaningful visual sensations. My feeling was that there will be a biological (stem cell-based) solution for blindness that will render the electrical stimulus-based methods obsolete.

That may well still happen but today I'm reading that Second Sight's bionic eye "Argus-II" has been FDA approved, which is amazing. And the patients seem to like it and value whatever level of prosthetic vision it provides, even if its minimal. Good for them! I hope this makes a big splash and a lot of money.

The really interesting question is how willing people will be to undergo the surgery in exchange for a fairly primitive visual system. My experience with blind patients during my postdoc is that they live very full complete lives and, while I'm sure they'd love to have their sense of vision back, they didn't think of themselves as missing out on part of life. Its a big grey area, but one that I'm looking forwards to seeing explored.

Brain Game Technologies

Two interesting things I saw today regarding neural interfaces and computer games. First, an article from IEEE Spectrum about using neural and muscle recordings to predict how much people are enjoying playing a video game. If possible, it might help developers determine how well their multimillion dollar game development projects will pay off.

The second link is even more intriguing: the NIH is now advertising an request for SBIR proposals surrounding the combination of neural modulation and video games. Scientists have long known that neural modulation (learning to operantly condition various brain activity) can be a way of dealing with various conditions such as ADHD, but there has been relatively weak development in terms of computer games and graphics that would make such an interaction robust and enjoyable for the user. Now NIH appears ready to put some money into this venture. I'll be interested to see what gets funded.

Double Arm Transplant - The Ultimate Prosthesis

Army Sgt. Brendan Marrocco has become only the seventh person in the world to receive a double arm transplant after losing all four of his limbs in combat. This is amazing and it really makes me appreciate that no matter how fancy the best electronics and robotics become, they are no substitute for Mother Nature. I'll be interested to see how his arm control progresses. Time to add @BMarr86 to my Twitter feed! Check out those scars! The full story is here.

NFL's $100M Study

The NFL is looking to give Harvard University a ten year $100M award to study and treat  injury in professional athletes. The award is to support study of all manner of injuries, not just the brain. It sounds as if the NFL has finally become scared out of its wits at the prospect of its liability to injured athletes. I mean ... $100M is a big big award. Big changes are in store, it seems.

Scott Mackler - BCI Pioneer

I've often felt that there should be more written about the patients who need and want brain interface technology. A few years ago I stumbled across this incredible story. There is a professor at the University of Pennsylvania who suffers from Lou Gehrig's disease and he runs his lab using a brain machine interface. It is an amazing story. An article about him from the Daily Pennsylvanian is here. His story was also told on 60 Minutes:


Stand-Up Wheelchair

I've been meaning to post this for a while - its a great promo video showing what a stand-up wheelchair can do and what kind of quality of life it can provide. While we're busy working on ways of interfacing to nerves and animating prostheses, its nice to remember that alternate technologies can often mean a lot more in the short term to patients.
