The MATLAB class at midterm: Comfort level


To end the first half of the semester in the MATLAB course, I gave students a lengthier-than-usual survey about the course — a sort of mid-semester course evaluation. I have a load of interesting data to sift through and analyze, relating to various aspects of the course and tagged with metadata about gender, GPA, major, whether they live on or off campus, and so on. I hope to finish analyzing the data before the semester is over. (Ba-dum-ching.)

One of the questions I asked was a mirror of a question I asked in the beginning: On a scale of 0 (lowest) to 10 (highest), rate your personal comfort level with using computers to do the kinds of things we do in this class. I’m thinking that there are affective issues about working with computers, and especially MATLAB, that are never discussed but which play a huge factor in student learning. (We seem to just tell engineers to suck it up and get to work, and assume that all MATLAB learners are engineers.) Here are the data, such as they are, for this question during the first week and at mid-term:

For some reason there were three students who didn’t respond to the midterm survey at all (it was worth 5 out of 15 points on week 7’s homework). I don’t know if the “4” and the two “8”‘s from week 1 that are missing from week 7 are the ones who didn’t respond to the survey; or if the “4” is now a “6” and one of the previous “6” people didn’t respond; or what.

Of course the striking thing here is that nothing has changed. I consider this a win on two levels.

  1. The course has, at the very least, not made students generally less comfortable with using computers, which I think is pretty positive considering the subject matter and audience here.
  2. The kinds of things we are doing with MATLAB have gotten progressively more complicated through the semester, so holding steady on comfort level while progressing in complexity is pretty much the same as progressing in comfort level. If you report the same comfort level after learning how to drive on the interstate as you did when first learning how to drive, period, it means that you’re more comfortable with driving in general than you used to be.
