Reflections on Back to In-Person Instruction and the Importance of Breaking Expectations

Last week, on September 1st, UMass Amherst resumed in-person instruction for the Fall 2021 semester. While I, of course, had some trepidation about having 300 people in a large lecture hall with the Delta-variant of the SARS-CoV-2 virus circulating widely, I cannot describe how happy I am to return to the classroom. In addition, the restoration of in-person instruction after such a long hiatus offers new opportunities for what I consider to be one of the most important goals of the first few meetings of any course: breaking expectations.

Lab groups and peer evaluations

This past year, I have been working to develop a series of labs that focus on scientific skills, as opposed to teaching physics content. These changes are motivated in part by the pandemic: I want to have authentic laboratory experiences that students can complete at home with limited resources. However, these reforms are also motivated by the literature which suggests that lab is better suited to the teaching of such skills as opposed to content:

  • Holmes, Natasha G., and Carl E. Wieman. “Introductory Physics Labs: We Can Do Better.” Physics Today 71, no. 1 (January 1, 2018): 38–45. https://doi.org/10.1063/PT.3.3816.
  • MacIsaac, Dan. “Report: AAPT Recommendations for the Undergraduate Physics Laboratory Curriculum.” The Physics Teacher 53, no. 4 (April 1, 2015): 253–253. https://doi.org/10.1119/1.4914580.

Lab groups are one of the necessities of such a large class. In order to respect the TA’s time and keep the grading load manageable, students must turn in reports as groups. Fortunately, I also think that learning to work in a scientific team is also an important goal of the lab experience.

This past semester, I have been trying to use Moodle to manage the lab groups and CATME to do peer evaluations. However, this has yielded two problems:

  1. The TAs must keep the lists in Moodle up to date and there is an unclear chain of command with regards to group management. Also, this requires a rather sophisticated understanding of Moodle and makes changing/managing groups difficult.
  2. The CATME protocol, while fantastic, is, I think, insufficiently transparent. Moreover, I must manage it. This is, frankly, too much load for me. I need a system that the TAs can successfully manage on their own.

I really like the multiplicative nature of the CATME results. A plan with which I am currently toying involves:

  • Have a number of points equal to the number of members in the team.
  • Each team member would distribute these points to their team members. Perhaps this would be done for a few different categories.
  • There would also be one optional point that could be given to someone who really deserves an extra boost. This would be a bonus: if everyone in the team neglects to do it, they will still all get ones (i.e. their score would be equal to their actual grade).
  • The result would be scaled in such a way that the final multipliers are between 0.7 or so and 1.05.

Obviously, this needs to be flushed out, but there are some key points for improvement here.

Brokk Toggerson’s end-of-semester activities for Physics 132 were profiled in the Center for Teaching and Learning Faculty Successes page. What are some ways to conclude your semester and leave students with a lasting and positive impression? As the end of the semester is approaching, plan some meaningful activities to use during your last class session(s) to wrap up the semester strong. Often students struggle to remember even the most important course content that they learned throughout the semester.

The machinery of very large courses

Well, a new semester has begun. Once again, my Physics 132 course is remote. Due to the unique challenges of this pandemic and remote learning, I am also completely in charge of the lab portion of the course for the first time this semester. This added responsibility, 14 lab sections and 11 TAs, plus my efforts to make the course as flexible as possible in response to the pandemic really has me reflecting on the machinery of very large courses.

This first week-and-a-half has been all about getting things moving. There really are so many pieces: the zoom schedule, the forum, the recordings, the lab manual, the homework, the TA schedule, the TA help sessions, getting all the TAs knowing what they need to do, then helping the 600 students understand it all! It really is like running a small company.

Personnel management should be a required thing for all graduate students.
