Smart article on Salon about the apparent strategy adopted by the big MOOC providers, which echoes that of the voucher/charter school proponents of the last two decades:
The plan is simple. First, declare a crisis in education that doesn’t actually exist. Second, declare that a for-profit model can fix the crisis. (This is easy when you get to invent the particular calamity.) Third, rather than starting small and building empirical support from experts in the field, seek sweeping legislative changes that lock your position into the system.
This isn’t, however, a head-in-the-sand piece about how everything is fine in higher ed. They point out that the MOOC providers have fabricated a story about how the problem is about access to college due to costs, when the real problem is about retention and degree completion.
The University of Kentucky is making a major investment in data analytics to try to improve student retention. The approach is described in an article at Inside Higher Ed:
Every time students open the app to check their course schedule or the date for the next Wildcats game, they may be faced with a quick question: Have you bought all your textbooks already? Do you own a tablet? On a scale from one to five, how stressed are you?
The university collects a student’s responses to these kinds of questions on a per-student basis. To that record, they also add a student’s interactions with the campus LMS and participation in campus events, which are tracked through a card swipe-based attendance and incentive system.
All of these systems alone represent a big investment in tracking, but analytics is about doing something with all that data. UK has made a major push to make meaning from the data by hiring a team of 15 data analysts to develop and refine a predictive model of student engagement. The end goal is to increase retention rates which, assuming they’re even marginally successful, will more than pay for the investment in all the staff and databases.
- The cost of attendance in-state is about $20,000, and $30,000 for out-of-state (source)
- The average financial aid award is about $10,000
- So net revenue per student is about $10,000-$20,000 (assuming in-state students); let’s call it $15,000 for simplicity’s sake.
- The freshman enrollment was about 4300 students
- A 1% increase in retention is 43 students
- 43 × $15,000 = $645,000 additional revenue
- $645,000 × 4 yrs = $2,580,000
- $2,580,000 ÷ 15 staff = $172,000 per additional staff line
And that’s making very conservative estimates throughout. That’s also not including the cost savings on the enrollment side of not needing to recruit as large a class.
We’re working our way through the major kinds of macromolecules in my Intro Cell Biology class — Carbohydrates, Lipids, Proteins, Nucleic Acids. Today I taught on the composition and structure of proteins. I really like the topic because it’s a chance to bring in so many of the concepts we’ve already discussed, like hydrogen bonding, polar vs. non-polar molecules, etc.
It’s also a topic that has been taught thousands of times before. A quick search on YouTube reveals hundreds of short videos, some of which are quite good, covering the same material. Yet there we were, talking about the same things: amino acids and peptide bonds, tertiary structure and protein folding. Why?
As best as I can tell, it’s because there we were, all together, all thinking about the same thing at the same time in the same place. Some of us understand more about it than others. Some have questions about it. But we all had made a commitment to be there with each other with the shared purpose of learning about proteins today. And I think it worked.
I’m starting to at least think about getting back into the flow after a few weeks away from the usual schedule. At the end of July I spent about a week at the annual meeting of the American Society of Plant Biologists, which was a great meeting for me this year. I heard lots of great science and got some excellent input and feedback from people I respect and admire. I also met a few new people and have some possible collaborations simmering now.
Since returning from the meeting, I’ve been mostly relaxing and taking some time away from the office. I’m getting some projects done around the house and spending time with the kiddos as much as I can before they start back to school next week.
While I’ve been away, it looks like Fargo has been doing everything but sitting still. I used it heavily to take notes on lectures and conversations while I was at the conference, so I’ve dabbled with some of the scripts in my menubar. I’m looking forward to thinking more about how to incorporate it into my class this fall.
Most of the day I worked on our poster, taking the opportunity to do lots of statistical tests to prepare for writing the manuscript, which comes next.
One of the comparisons I want to make is within a given treatment, across different time points. I’ve come up with a heat map presentation that I think I’m happy with, but I’m not totally sure yet.
In this graphic, green indicates a significant increase, while pink represents a significant decrease. I think this highlights the key points I’m trying to make, but I’m going to sleep on it.
Tomorrow I’ll try to write the rest of the explanatory text so I have a few days to let it mellow before sending it off to the printer.

We’re just back from a quick road trip, a micro-vacation to explore nearby Cleveland. We visited the Rock & Roll Hall of Fame and Museum and the Great Lakes Science Center. I’ll write a little more about those later, but I wanted to capture my initial impressions of my first connected road trip, by which I mean one with an iPhone and a data plan.
In a word, it was liberating. Not having to nail down all of our plans in advance, we could be more flexible and adapt to the energy level of the kids. This is another way of saying we could be ourselves and pretty much make things up as we went along.
Having turn-by-turn navigation was huge, and Google Maps was outstanding. I used Apple’s Maps to start, but after giving Google Maps a try, I stayed with it. My stress level was noticeably lower knowing I didn’t have to figure out where to turn to get back to the highway from the museums. There were a few little, tricky turns that I never would’ve found without the help.
I quickly found a great little pocket of restaurants to choose from near the hotel, including a Thai place and a Lebanese cafe, where we ended up eating.
Of course, none of this is impossible without a connected phone. I know I’m late to this party, too, having settled for iPods and iPads until I could get an iPhone on my terms, not those of a carrier. Knowing we would be traveling this month, I paid for a month of data, and will likely return to a minimal plan next month.
Interesting to note that, even when using it as the impulse struck, I only consumed about 18 MB for the whole trip. I could probably get by on the 500 MB data plan and still get a lot of value when we travel.
Yesterday I wrote briefly about getting to work on a poster to present at a conference in a few weeks. After working on it for a bit, I’ve decided to switch to Pages from OmniGraffle.
While OmniGraffle is certainly more than capable for the task, I’m finding it almost too flexible. In the same way that I’m drawn to outliners for writing, I’m drawn to Pages for a little more structure in the layout process. I could probably figure out how to make OmniGraffle give me that structure, it’s already done for me in Pages.
I created a new document in Word Processing layout, which may not seem intuitive for layout work, but it keeps me from having to fiddle with making all the text boxes individually. After creating a new file, I changed the page size to my poster dimensions â€“ 30 inches wide and 40 inches tall in this case. Then I put in the title and author details and inserted a layout break. After the break, I set the layout to 3 columns and let the app automatically size them.
I’m not a big drinker, but somedays just seem to call for a little something more than water or iced tea. Even though I’ve been a home brewer for many years, lately I’ve found that beer makes me sluggish and sleepy more than anything, so I’ve been sampling as many ciders as I can find this summer.Arsenal 2017 movie
Tonight I picked up a few singles at one of our great local craft beer shops, and one of them was Harpoon Craft Cider. It’s amazing the difference in complexity between this and, say, the Michelob hard cider I bought before it. It’s like the difference between eating an apple and an apple-flavored Jolly Rancher! It’s a very well-balanced, light, crisp drink with a complex collection of flavors. The 4.8% alcohol is low enough that I can do other things while drinking it (like write this), yet still feel a little more relaxed.
The only slight downside is that I’m getting a little hint of a cedar or wood note. It’s not enough to make me not want to drink it, but it’s there nonetheless. I’ll buy it again!
I started working on our poster for ASPB 2013 today, revising my student’s previous version to add new data and generally smooth out the rough patches. I’m using OmniGraffle to do the layout, since I don’t have to share it with anybody else during the editing. It’s a bit of a luxury not to have to use PowerPoint for the layout, which is the least common denominator that I’m usually stuck with for this job.
Rather than simply transfer our figures on the old version into the new one, I’m going to take this opportunity to make publication-quality figures with my tool of choice, DataGraph. This is also a great chance to think about the data we have and what we still need in order to finish this project.
I’m trying to use a grid-based layout for the poster to impose some structure behind the scenes. The poster’s 40 in wide, and I’m working on 4 Ã— 9.5 in columns at the moment. Not sure I’ll stay with this, but it’s a start. I’ll have to see how well the various graphs fit this grid before I commit to it, and I’m still working on those.

It looks like the next version of OS X will improve on AirPlay, turning an AppleTV display into a full-on display for the Mac and overcoming some of the severe limitations I’ve experienced and written about previously.
Here’s what Apple says about the new feature, called AirPlay Display:
With AirPlay and Apple TV, your HDTV works as a fully functional display. So while you’re using your TV to present a slideshow or stream a video lecture, you can take notes on your Mac or chat using Messages.
I’ll revisit this issue when the next version of the OS ships, later this fall.
I’m also reasonably excited about iBooks for Mac, as this will bring the iBooks store into closer feature parity with the Kindle store. As it stands, I can read my Kindle books anywhere, but my iBooks are restricted to the iPad and iPhone/iPod touch. The demo looked good, and the big advantage of interactive, high-quality artwork and feature-rich note-taking could potentially tip the balance in favor of iBooks for me.
