Concept maps

Drawing concept maps at the beginning, the middle and the end of the course.

Using concept maps in teaching is something that I first tried last year in both the GEOF130 and CMM31 courses. The idea is that coming in, students typically don’t have a very good overview over the topics and concepts that are going to be covered in an introductory oceanography class, but that that will hopefully change over the course of the course.

The reason for trying to use concept maps in teaching was twofold.

Firstly, I wanted students to see how they gradually learned more and more about oceanography, and how they started to see connections between concepts that initially did not seem related.

Secondly, I am a big concept- or mind-map drawer whenever I need to study complex topics. For every big examination at university, be it in physics or ship-building or oceanography, I have drawn concept maps (even though at the time I didn’t know they were called that, and I was using them intuitively to organize my thoughts, rather than purposefully using them as a method). So why not try if it helps students study, too?

So how did it work in practice? Students were asked to draw concept maps during the first lecture, during a lecture some time half-way through the course, and at the end of the course. I collected and scanned the concept maps (out of my own curiosity) but students always had access to them and were encouraged to work on them any time they wanted to. Concept maps got impressively complex fairly quickly, and students reported that the maps helped them both to see their progress and to organize their thoughts.

For one of the courses, I used the concept maps as basis for the oral examination in the end (which was a lot more time-intensive to prepare on my part than I had imagined, and I wouldn’t do that again) and for part of the grade. For that, I had written down a list of concepts that I thought they should definitely have learned in my course, and a list of connection between concepts that I thought were crucial, and I just counted them and ticked them off on a list. Again, this was a lot of work and I am not sure if I would do it again. Not because it was so much work, but because I am not sure if by grading basically whether students went through the table of contents of the textbook and made sure all the headings were included in the map, I am encouraging just that and nothing more (although I actually don’t think this is what happened in either of the courses, but still, thinking of constructive alignment, basically naming concepts is not a learning outcome I want from my class).

So in conclusion, I would definitely use concept maps in teaching again (Isn’t it impressive to see the maps develop?), but not as a tool for evaluation.

P.S.: A big THANK YOU! to the student whose concept maps I am showing here (and who wishes to remain anonymous, but kindly agreed to let me use them as an example).
