technical paper

As part of our effort to develop a concept inventory for statistical mechanics, we have interviewed a number of students who have taken a thermal physics course, at both the undergraduate and graduate level, about their understanding of the statistical mechanics topics taught in the thermal physics curriculum. The questions asked during the interviews were formulated with input from experts in the field, and will later be fleshed out into multiple-choice questions. Here, we report some of our intermediate findings about the students understanding of some of the topics.

Insights into student understanding of statistical mechanics

The global pandemic caused by COVID-19 has provoked an abrupt disruption of postsecondary education on an unprecedented scale. The present study reviews the nature of laboratory work and demonstrates how remote labs provide a viable alternative to in-person learning. Nearly every college in the U.S. has transitioned to remote learning in a short time frame. Regardless of when students return to higher education institutions, this disruption will influence the way laboratory-based coursework is conceptualized. With over half a million undergraduate physics students, the advantages of remote learning may expand STEM access to students who may have been traditionally underrepresented. Physics faculty have been generally hesitant to implement online labs for various reasons such as time, inexperience, and questionable rigor. This paper reviews the historical progression of laboratory work in the U.S., with a critique of the evolving nature of its purpose and relationship to students’ performance in physics.

Rethinking the value of remote undergraduate physics laboratory work

In response to the COVID-19 epidemic, Seattle University moved all courses to remote instruction for spring quarter 2020. The Modern Physics Laboratory course PHYS 2060 was adapted by organizing it around the building, programming, and implementation of a home-built Geiger-Müller counter. Students had no prior LabVIEW experience and most had no electronics experience. They were provided with a National Instruments myDAQ board, an electronics breadboard, electronics components, and a schematic diagram [1] and given synchronous instruction via Zoom. They wrote LabVIEW VI's for lab bench tools and automated data acquisition. They designed and executed three nuclear physics experiments using their own software and hardware. Relative to the in-person format of the course, students executed a narrower range of experiments and did not study historic experimental literature, but gained data acquisition and electronics skills, experience in building and troubleshooting apparatus, and the satisfaction and self-confidence of making their projects from scratch.

With funding from NSF’s DRK-12 program, the Center for Astrophysics | Harvard & Smithsonian is researching and developing a next generation browser-based spectra visualization and analysis tool, The Spectrum Laboratory: Investigating the World of Color. Accompanying curriculum investigations enable students to use spectra from publicly available research databases -from atoms and molecules, to plants and pigments, to stars, galaxies and exoplanets - to support a wide range of authentic inquiry projects in the classroom. Spectroscopy is the universal analytical tool of science, yet it is typically touched on only briefly if at all in most people’s pre-college experience. Through this project we are testing the hypothesis that repeated opportunities to generate and analyze graphical spectrum plots and data, in association with real-world data and inquiry-based tasks, can help learners productively reorganize and prioritize existing ideas about light and color phenomena, and support them in productive participation in scientific practices.

The Spectrum Laboratory: an online learning environment for authentic inquiry

My students are used to learning physics through laboratory experiments, demonstrations, and projects. To simulate similar hands-on learning experience in a virtual classroom and make the subject more relevant, the students completed “Physics At Home Project”. They performed two physics experiments or demonstrations at home, took pictures of five things related to physics, explained how the pictures depicted physics concepts and principles, created video and QR code of their work, and presented the project via Teams, an online platform. The outcome were varieties of physics topics including, forces, Newton’s laws, heat transfer, specific heat, energy conservation, impulse-momentum theorem, and collision. During the presentation, the students were able to use physics vocabulary terms to discuss their project. They discovered relevance in some materials learned in physics by observing that everyday things in their environment are related to physics. Also, they learned how to present work in an online platform, and make YouTube video and QR code.

Sharing Physics Through Sound: Undergraduate Outreach

This summer, Wake Forest University's introductory calculus-based physics courses were delivered fully remotely for the first time. The laboratory portion of the course was primarily conducted using the iOLab Wireless Lab System. We moved to the system on relatively short notice. We conducted lab meetings through synchronous sessions on Zoom to introduce each lab. Following the sessions, students worked on the experiments independently or occasionally in pairs. I will report some of the successes and challenges we experienced.

Conducting a Summer Introductory Laboratory on Short Notice Using iOLab

The rapid shift to online instruction presented daunting problems, but also an interesting question: What do we REALLY want students to learn from an introductory physics lab? At Cuyamaca College, we decided that we cared that students (1) connected abstract course material to something concrete, (2) understood how to collect, analyze, and present data to test a scientific idea, and (3) could communicate their own scientific understanding. To do this we designed two simulation based labs and a project. The lab project, a multi-part assignment spread over the remainder of the semester, asked students to propose, design, run, and present a lab themselves using tools they had at home or could get safely and cheaply. By providing a few examples and a lot of support, we received some truly remarkable projects ranging from DC motors and electromagnets to pendulums and egg drops. Student feedback was overwhelmingly positive.
