A Veritasium Video on the Learning Styles Myth

This video, from one of my favorite educational YouTube channels, takes on the learning styles myth. I have found this myth to be very harmful in my own classes: students end up having a fixed mindset about their ability to learn physics for which they use the learning styles myth as a support/excuse. I really wish that we could do away with this myth and present all information in all the modalities that support that type of information to help all learners do their best.

My Quantum Life – A Review

The seeker after the truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them, but rather the one who suspends his faith in them and questions what he gathers from them, the one who submits to argument and demonstration, and not to the sayings of a human being whose nature is fraught with all kinds of imperfection and deficiency. Thus, if learning the truth is the scientist’s goal, then he must make himself an enemy of all that he reads, and, applying his mind to the core and margins of its content, attack it from every side. He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency.

Quoted in My Quantum Life: My Unlikely Journey from the Street to the Stars by Hakeem Oluseyi

I just finished listening to the audio-book of My Quantum Life: My Unlikely Journey from the Street to the Stars by Hakeem Oluseyi. This book was just fantastic. While, Prof. Oluseyi is clearly writing for a general audience, he does not shy away from the physics details. Having a physics (and academic) background, I suspect, makes the book more enjoyable.

Brokk Toggerson contributes to ACUE Inclusive Teaching for Equitable Learning Micro-credential

Brokk Toggerson was recommended by the UMass Amherst Center for Teaching and Learning to contribute to a micro-credential on Inclusive Teaching for Equitable Learning developed by the Association of College and University Educators (ACUE). Brokk participated in an in-depth interview on a variety of questions. Ultimately, ACUE selected a section on developing effective teams for incorporation into their lesson.

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:

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.
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.

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.
