Taking the plunge with a new book format and a new homework system for Physics 132

This semester, I have decided to finally take the plunge for migrating the Physics 132 textbook from the pdf generated by the OpenStax CNX platform to a much-easier-to-edit format of Pressbooks and simultaneously moving the online preparatory homework from Pearson’s MasteringPhysics (to which I will not link, search for it if you are interested) to Edfinity. This is quite a journey and a lot of work, but I think it will pay off.

The new book can be seen at http://openbooks.library.umass.edu/toggerson-132/. It is being built as we go for the current semester, but have a look!

A new direction for the Physics 132 labs

During the Spring 2019 semester, in addition to several changes in the lecture portion of the course, Paul Bourgeois, David Nguyen, and I continued to make changes to the laboratory portion of Physics 132. Motivated by this article from Physics Today, we decided to make our labs much more focused on teaching fundamental data analysis skills as opposed to physics concepts. We also added structural changes to the lab portion to promote in the students a sense of importance and ownership of what we were trying to teach. In general, I think that these changes were, by the end of the semester, positively received and provide a strong way forward for future lab developments in Physics 131 and other courses within our department.

Reflections on P132 Spring 2019

The semester is (well) over, the grades are in, and the course evaluations have been returned. Based upon this feedback, I must say that I think the strategy used this past semester to apply the TBL strategy in the large lecture hall of Physics 132 was fairly effective. Our changes to the laboratory curriculum (developed in conjunction with Paul Bourgeois and David Nguyen) also seemed to be positive. This post will focus on the team-based learning aspect of the course in the lecture hall. I will reflect on what I did differently and how it compares to both the previous two semesters’ iterations of the course. I will also consider my other prior experience teaching in large lecture halls. The lab will be dealt with in a later post.

Note: this material has now been replicated on the page describing P132

How to go about directing future improvements to courses?

I am at an interesting point for the first time. I have been teaching the 131 and 132 courses here at UMass for several years and thinking about how to seek continued improvement in an effective way. I know of some faculty who continually do overhauls to keep things interesting and fresh for themselves and for their students. This technique has merits as an interested teacher has intrinsic benefits.

I want, however, to continue to improve my courses in a way that builds upon the successes.

Reflecting on previous iterations, most have been centered on a key pedagogical principle: active learning, team based learning, backward design, flipped, etc. I think this path still has room.

I am thinking about those things that students mention as being particularly engaging: the myosin fibers in the energy unit, the spontaneous structure formation in the entropy unit, the circuit-based study of the neuron in 132. All of these have what is called by Redish et al as “biologically authentic examples.” I would like to both continue to find more, and find ways to integrate them more deeply into the curriculum. Perhaps a case-study type format?

Website update on educational resources

There has been a significant website update on our educational resources. All the stuff formerly under “Other Projects” has been split into Free and Open Educational Resources and Self-Efficacy and Attitudes Study.

Under Free and Open Educational Resources, you can find out about our work developing free-to-students textbooks for Physics 131 and 132. There is also a library of the 3-D models that are being used in Physics 132 to increase accessibility and provide multiple means of representation.

Have a look! Maybe these can be useful for your own courses!
