Confused at a higher level

The view from a liberal arts college physics department (and deanery)

What I wouldn’t have learned if all my physics classes were from MITx

Posted by Melissa on February 26, 2012

This past week there was a bit of a brouhaha at my alma mater, Smith College. Carol Christ announced that she would be stepping down as president. When asked about her greatest accomplishment, Christ said, “Smith has become much more diverse. 13% of the class of 2015 are international students and a third are U.S. women of color. A decade ago 8% of our students were international, and 21% were U.S. women of color.” I’m excited to see Smith taking steps to diversify the student body. Not all alums share my opinion, however, and one, Anne Spurzem ’84, wrote a letter to the editor of the Sophian (the college newspaper) to share her thoughts. You can read the letter yourself — there are no words to describe the piece of work that it is.   What has buoyed me about this letter is how strong and unified the response of the community (both current students and alums) has been, and how unapologetically the community has affirmed the value it places on diversity, as well as providing a chance for Smithies to reflect on how Smith has shaped them. (Christ herself responded to the letter, and there have been many on-line responses, one of my favorite being this tumblr site.)

On a personal level, I owe much to the Smith College community, and I owe Smith for much more than the knowledge I acquired in my classes. I could have gained that education at many different colleges. Rather, what I gained as a result of my time at Smith was an open-mindedness, a confidence (combined with a relentless call to do things that push the limits of that confidence), and a sense of responsibility to past and future generations of women and a sense of possibility for the present generation. Smith provided me a time and a place to discover who my best self could be, within a community that was simultaneously supportive and challenging. I learned from difficult discussions with classmates and faculty and from casual conversation at Friday afternoon tea, from informal interactions with professors who taught me what expectations and responsibilities come with being part of an academic or scientific community, and from listening to and talking with alums at Rally Day and Ivy Day.

In higher education today, with the introduction of courses like those offered by MITx and the move towards badges to certify skills and knowledge, there is a push to allow people to selectively consume the educational content they want, to pick and choose skills and knowledge that they think will prepare them for careers. What I fear is lost in this focused consumption of educational experiences is the individual growth and metamorphosis that results from being part of a community that challenges your beliefs, that pushes you to rethink what you know and how you occupy the larger world, that encourages you to engage respectfully with difference, and that holds you accountable for the responsibilities that come with being a liberally educated citizen. Those things can’t be taught in badge-worthy snippets, and yet they are the portions of my education that I value most. That’s not to say that the knowledge and skills I learned in math methods or quantum mechanics aren’t important, but the sum of that knowledge doesn’t add up to the whole of my education. While I see a place and possibilities for some of the new focused approaches in higher ed, I would miss the more abstract lessons that I learned in my four years immersed in the Smith community. Of course, as Ms Spurzem’s letter clearly illustrates, just belonging to the community does not guarantee educational outcomes of, for example, open-mindedness, but that doesn’t mean there aren’t benefits to a residential educational community.

Something new: Lab-based performance assessments

Posted by Melissa on February 10, 2012

For all kinds of reasons, this has been one of my most brutal terms at Carleton. On the teaching front, I have a new prep, electronics. I loved electronics as a student, and I’m thoroughly enjoying the opportunity to delve into the material again. I also decided that I wanted to try out a couple of new (to me) pedagogical strategies in this course, which means that I stacked the extra work of exploring new teaching techniques on top of the extra work of a new prep. One of the things I’ve done in this course is to jettison traditional quizzes for lab-based performance assessments. The idea is that electronics is most useful if you both understand the theory and can apply that theory to build interesting/useful circuits. Traditional quizzes assess theoretical understanding, but do little to assess how well a student grasps the hands-on aspects of things, including troubleshooting.

As a student, my electronics course included a couple of lab quizzes. As a teacher, I’d never tried giving lab quizzes before this term, and I wasn’t sure how to approach these. However, with a bit of a push from former colleague Kris Wedding-Crowell, who had tried lab quizzes in the contemporary experimental physics course, and from Scott Seagroves, the lab instructor at the College of St Scholastica, I decided to take the plunge and try lab-based performance assessments. Now in the midst of administering my second one this term, I’m glad I took the risk.

How does a typical performance assesment work? I give the students the schematics for a circuit, and ask them to make predictions about several aspects of its behavior, or what might happen if a component fails open or shorted. Once the student has done the theoretical work and come up with predicted values, I ask the student to go to lab, build the circuit on the breadboard, and test their predictions. If there are discrepancies, the student can either try reworking the theoretical prediction or reconfiguring the experimental set-up. The benefit of this approach is that I get a good sense of what students understood and where they have trouble. It feels like a much more authentic assessment of what we do in the class, equally weighting theoretical understanding with practical know-how. The downside? Scheduling all 15 students to take the assessments requires a lot of time because I have to be present in the lab to watch as they build and test their circuits.  Since time is a particularly scarce commodity this term, this is a significant drawback. Nevertheless, I have once again been reminded that jumping out of my teaching comfort zone, while scary and demanding, can be rewarding, and it keeps me growing and learning as a teacher.
