Are grad classes a waste of time? February 5, 2012

I have seen both Gears and Massimo post comments about how grad classes are a waste of time.  Last week, Gears said this in his EngineerBlogs post (which I’d like to address several points, but this will have to suffice for tonight) and Massimo has suggested ‘workshop’ classes. I have to say that I disagree with both of them, but I think it’s because of my weird background.

For review, I did an undergrad in physics with a math minor, my masters in electrical engineering, and my PhD will officially be in geophysics (as was all my coursework) though my project is actually on solar physics.

Honestly, I’m not sure I could have done that without the coursework.  On the other hand, I think my attitude would be different if I’d stayed in one field. In my work in electrical engineering, I use almost every class I took, especially the grad courses.  I use antennas and microwave engineering a lot…so much so, that my circuits classes are probably the most rusty.  (I know, that’s completely backwards for an EE, but that’s how it goes sometimes.)  I find myself often wishing I’d had the opportunity to take some advanced signal processing, as well.  And one of the most useful courses was numerical techniques in electromagnetics.  Not only does it help me with the work I’m doing in EE, it’s also helping with many of the things I’ve run into looking at geo- and solar physics research.

The flip side to this is that if I’d continued on to get a PhD in EE, any further coursework would not have been terribly relevant.  I think there’s an optimum point, and that may have come earlier if my undergrad was in EE.

My classes in geophysics were not as useful, and I think there were probably 2.5 classes that had anything at all to do with my research and what I’m doing now.  Realistically, for the stuff I was interested in, I probably should have looked at a PhD in physics or astrophysics…but that may not have been much better if I was taking a bunch of classes on stuff that had no bearing on my research, either (which is likely).  However, the 2.5 classes that were useful have been REALLY useful.

I’ve got a breadth in classes that most students never get.  This is one thing that I think is a bit of a sticking point for some students.  Most places have a ‘breadth requirement’ – i.e. so many classes outside of their department.  I think this is a good thing as it helps people to see what other types of things could be relevant to their research.  I really think this is something that should be required because of all the ideas that come from seeing how different disciplines approach their fundamental problems, and even having some exposure to what those problems are is a benefit to students.

The real problem, in my opinion, is that so many places require a LOT of credits.  It’s fairly common in most good EE programs to require somewhere between 50 and 60 credits of JUST coursework.  I don’t like the idea of no classes, but I really think you could trim them back and just make students take classes that are relevant to their research as well as a couple classes for breadth.  I was very disappointed with my PhD program because once you hit advanced candidacy status, you’re not allowed to take any more classes unless your advisor is willing to foot the bill.  Not likely because most advisors want their students working on their research and getting done (not that I blame them).  The down side is that there are a couple classes that I could have really used but was unable to take because they didn’t fulfill the requirements for my degree.  Most of my classes had to be in the department as I’d already fulfilled my breath requirement, so taking a class here or there outside the department was viewed as a waste of time because they didn’t allow me to tick off some of those boxes in the red tape.  And of course, it becomes obvious that you would really benefit from a course once you’ve hit advanced status and can’t take any more.

It would be nice if there was a system where your advisor could sit down with you and figure out where you’re interested in going research-wise and plot a course through the classwork that makes sense and is flexible.  Wouldn’t it be nice if you discovered you need to learn about a particular topic and could then go take the course on it? It makes more sense to me than filling in boxes to get to a certain number of credits or hedging bets that something will be useful later on.

Let’s face it: research degrees are already very specialized and take a long time, so it would make more sense to cut the classes down to those that are relevant.  This would ideally save time without sacrificing the background required for a research project. Finally, a really good option, which more universities ought to allow, is independent study classes.  During my MS, I took one class as an independent study working on emag stuff.  It was awesome as I got the material I really needed in a more structured way and was able to do a project which (I’m still hoping) would be a foundation for some decent research down the line.  Therefore, I don’t feel grad classes are a waste of time, as long as they make sense, and I wish universities would be more flexible in some of their requirements.

GEARS has an interesting post discussing his experience with both American and European styles of postgraduate education. At the end, he asks:

What do you think? Would you rather have defined your own series of independent studies than taken classes? How many classes during your graduate work have been useful for you and your research?

During my graduate career, I’ve taken classes in electrical engineering, math, geology/geophysics, and even a class on teaching.

I guess having this broad background gives me a different perspective. I understand what he means on being distracted by pretty, shiny things in new classes. However, if I felt interested in the topic matter and class, I never felt like learning about those things was a waste of time. I view it as needing some breadth in my field.

I also have the experience of bouncing around on a LOT of different projects, so it’s amazing the stuff I’ve realized I should have had but did not, as well as the things that I thought I’d never need but have.

Those pretty shiny things usually end up as some sort of idea for a research project later on. This is also the same reason it’s good to know scientists from a lot of different fields: the ideas and input they can provide are very exciting.

In my personal view, the real distinction between a class that useless or not are the ones where I felt like I got a lot out of it. By the time I was done taking classes, I realized that a good half of the classes I’d taken were a waste of time simply because of poor instruction. I would have been better off studying things on my own, perhaps with some guidance, than sitting in a classroom with a professor who views teaching as a distraction from his or her real purpose.

Teachers who are excited about their topic as well as effective communicators make a class worthwhile, even if you never directly utilize the subject they present. Sometimes you can find connections and analogies that help inform the work you’re doing. Or maybe you see something in one field that no one in the other knows about. (I’ve got about 3 or 4 of those I wish I had time to work on.) And then there’s simply the fact that you’re increasing your breadth of knowledge of your own field.

As far as topics directly pertaining to my research, I’d probably say about half of my classes were relevant (keeping in mind that I’m doing things in two subfields of engineering and another area for my dissertation). But those half were very much because the professor made the material accessible and relevant, helping me to realize I could use the information in my research. I know some information is inherently useful, but if the professor doesn’t teach it that way, you’ll never realize it.

I have more thoughts on the topic which are more relevant to homeschooling…so I’ll save those for another post.
