As I wrote in my last post, I do research. But doing research is not easy if you aren't allowed to apply for major research grants. Sometimes, though, you get lucky.
I've got a good relationship with Nelson Education--the Canadian imprint for Cengage Learning, publisher of a number of textbooks I use in my courses, and also my employer (I do consulting for them on their Canadian psychology websites). So late last year, the local rep asked if I'd be interested in helping them evaluate the CengageNOW platform (which includes online etextbooks and interactive study guides). Oh, and they'd provide free access codes for students in my Perception class--but unfortunately, only for about half the class.
OK, I've just been designing this kind of experiment for a couple of years: Does using an etextbook cause students to do better, worse, or exactly the same in a course? I jumped at the chance. Half the class would get a free access code to the etextbook, the other half would use a regular printed textbook. At the end of the course, I could compare the two groups in terms of the dependent variable of final grade. Perfect! But who would get the free etextbook and who would have to pay for a textbook? How would that be decided? And is it fair that some students get something for free, and others don't?
These are important questions to consider. Obviously, the fair thing to do (and also the most obvious, from a statistical point of view) would be to randomly assign students to the etextbook and printed textbook groups. However, some students may not want to use an etextbook--even if it's free. In that case, I would have to exclude them from the study data, but then I could use their access code to give to students who registered late. The issue of free, though, I couldn't overcome. Nelson was not willing to pay for free printed textbooks for the other half of the class (about 107 students). Rats! This means I've got a confound that I couldn't overcome: students who got the etextbook would also be getting it for free, whereas students who bought and used the printed textbook would be paying for it.
If there are any difference in grades between these two groups, it could be because of the resource used (maybe reading an etextbook is more fatiguing so students spend less time reading, compared to a printed textbook--or maybe it's easier to read). Or it could be because of the "free" aspect (students feel less "invested" in the free etextbook, so don't read it as much as they would a printed textbook that they had to pay money for). Argh! Not so perfect. But it was the best I could do under the circumstances; I'd need almost $20,000 to buy textbooks for half the class!
There still were many more hurdles to overcome. Next: research ethics and the maze that is HERO.

The Research: The Opportunity
The Research: Primary vs. Secondary
As a scientist, I do research. The first thing the word “research” brings to mind is probably experimental research. But this is only one method under the broader umbrella term of empirical research, which can include other methods like surveys, for example.
Another way of dividing up research into different kinds is into primary and secondary. In primary research, you collect original data; you’re discovering something no one else has ever known (you hope!). In secondary research, you are going through data that has already been collected. Maybe you are looking for something specific, or maybe you want to do a (formal, statistical) meta-analysis. (This doesn’t mean that every time you do a Google search, you’re doing secondary research--but secondary research might employ an Internet search now and then. More likely, I’ll use PsycINFO or MEDLINE.)
I do a lot of secondary research in prepping my courses. For example, when I created my lecture on synesthesia, I did a lot of secondary research--searching for studies, reading and analyzing them, and synthesizing the information in a systematic, coherent way. (At least, I hope it’s coherent! ;-)
I also do some primary research. It’s not something that I’m required to do in my role as Faculty Lecturer (but it can be a lot of fun to do). In fact, the University makes it hard for contract academic staff to do primary research: we are not allowed to apply for research grants. As you can imagine, having no money makes it kinda hard to do research. Unless: a) you’re rich, b) you have a sugar daddy, or c) a publishing company comes to you with a bunch of free stuff and asks if you’re interested in using it to do a study.
Late last year, I had the opportunity for option c). In the next few posts, I’ll describe the steps in the research process, ending up with a summary of my results.

The Value of Your Degree
I’ve posted about The Best Job in the World, according to a number of metrics. Now, a new study has been released, looking at the earnings of people who hold a bachelor’s degree.
Researchers at Georgetown University Center on Education and the Workforce analyzed US Census Bureau data on over 3 million bachelor’s degree-holders who graduated over the last 40 years. Specifically, they recorded the median salaries they earned in 2009; this means that they took a cross-section of people currently in the workforce (it didn’t just look at people who graduated in 2009).
I’m sad to report that the field with the lowest median salary is Psychology and Social Work (P&SW) at $42K (range: $29K to $53K). Sob. Below is the breakdown within P&SW (from The Chronicle of Higher Education):
The lowest is counseling psychology, ringing in at a paltry $29,000 per year. At the top of P&SW is I/O psychology (those who work in large companies, measuring and improving performance and/or wellness). I guess those companies pay pretty well; the pay is almost double that of the poor counseling psychology graduates.
But wait--what are those lowly counseling psychology-degree-holders actually doing? They’re not working as counseling psychologists. Why not? Generally, you can’t, not with just a Bachelor’s degree. Maybe they just got their BA and are now working in retail. On the other hand, you can work in I/O psychology with “just” a bachelor’s degree.
Also, the US economy isn’t in great shape. The data came from 2009, when the job situation was pretty grim--not that it’s great today. It’s possible that some people had their salary cut, or at least not increased recently. Still, the numbers above are based on full-time, full-year workers with a Bachelor’s, not part-time workers.
Finally, those who hold higher-level degrees like a Master’s or Ph.D. earn more. According to the report, median earnings of those with a graduate degree in P&SW was $60K, moving P&SW up to the third-lowest field.
So, did you make a bad choice of major? Should you have taken engineering (overall median: $75,000)? Or computing science (overall median: $71,000). Maybe we’re just all in this for the love of it.

The Random Facts 2
No, still no Twitter account. Why? I can't come up with a good name. Is “Sh*t my prof says” taken? So, more random facts (and some questions).
- First, the Taco del Mar by my house closed, then the Taco Bell closed. What have I done to offend the taco gods? I am currently leaving offerings of money at the nearby Mucho Burrito...
- never get three dental fillings a couple of hours before teaching a class
- Me: “What are you watching?”
My wife: “Um, Keeping up with the Cardassians.”
I wonder to myself, hmm...Elim Garak, or Gul Dukat?
- Is a public toilet seat still warm from the previous occupant gross, or kinda nice?
- Oh, and don’t hold anything over a toilet that you want to keep.
- Have Cadbury Crème Eggs gotten a lot sweeter since I was a kid, or have I just gotten more sensitive? That’s what I thought.

The Spring Term, 2011
I've written about Spring Term before, describing my misconceptions about the kind of students who take courses in Intersession (Spring and Summer Terms), and about their reasons for taking them. This time, a little bit about one of the greatest challenges in taking an Intersession course: time.
Courses in Spring (and Summer) Term last for 6 weeks. Unless you've signed up for a 3-week Spring or Summer Term course. That's right: first day of class to final exam in 3 weeks. I've taught 3 weeks courses before, at another institution. It's 3 hours of lecture every day, Monday to Thursday. Then on Friday there's a midterm and another lecture to round out the 3 hours. It's brutal. Don't even think about taking two of these monsters at the same time. Your social life will go out the window and you'll have to catch up on your favourite TV shows later. It's just go to class, read the textbook, go to class, read the textbook. So, in contrast, a 6-week course doesn't sound too bad.
In 6-week courses, there's "only" 70 minutes of class every day, and an exam "only" about every 2 weeks. Let's compare (labs aside, assuming a full course load):
- "regular" Fall/Winter Term: 770 minutes (about 12.8 hours) per week in class (five courses)
- Spring/Summer Term: 700 minutes (about 11.7 hours) a week (two courses)
- Fall/Winter: 7.8 hours/week
- Spring/Summer: 11.7 hours/week
The point of all this silly number crunching? Don't take Intersession courses lightly. Be prepared to devote your time appropriately--these courses still count toward your GPA. It's tough to concentrate on the yada-yada of your instructor when the sun is shining and the birds are chirping. *sigh*
If you've taken Intersession courses before, what are your tips for making it through?

The Earth Day
Happy Earth Day, Earth! And to everyone on it! (Sorry, astronauts on the ISS, you don’t count. But hey, you’ve got an awesome view out the window. Of the Earth.) It's good to have a reminder about the value of the Earth, our environment, and ways to protect it.
At work, I strive to be environmentally friendly:
- No recyclable paper gets thrown in the garbage. Any paper that goes into the recycling almost always has both sides used. I admit that I do use a lot of paper--exams, mostly. You wanna help me recycle exams? Heh, nice try. They all go to be shredded and then recycled.
- Dead batteries from the wireless mics I use get dropped off in an ECOS
- I turn off the lights in my office when I go to class; I also turn off the lights in the bathrooms in Bio Sci when I leave. (Sorry about leaving you in the dark that one time, guy in the stall. Oops!)
Speaking of family, here are some things we do:
- We don’t buy bottled water; every family member has their own reusable aluminum bottle (so no fighting over the one with zoo animals on it!).
- In my house, I’m famous for eating food that’s past its expiry date. Long past. Hey, I hate to waste food. What's a little borborygmi?
- Every garbage day, I put out more blue bags than garbage bags--in fact, no one else on my block puts out as many blue bags as I do. It takes me over an hour a week to clean, rinse, sort, and otherwise prep all of my family’s recyclables.
Could I do better? Absolutely. I could bring my own rechargeable batteries to use in the wireless mics. I could try to always remember to shut off the computer and turn off the lights in my classrooms, if it’s the last class of the day. I could buy products with less packaging to reduce my recyclables.
