Well…unless you have been on a very long space voyage and been out of communication with Earth, or else if you have been living deep underground in a cave with no internet access, most of you reading this update will be aware that we have been in the midst of a major upheaval of our normal behavior patterns since mid-March of this year. The COVID-19 pandemic has affected all of our personal lives, and it extends profoundly into our professional activities as well. Of course, the Forum on Education (FEd) has also felt the repercussions of the recent health crisis.
For me, the first realization that something was amiss occurred while I was in Denver awaiting the start of the March APS meeting, at which FEd was sponsoring or co-sponsoring five invited sessions, including the prize session for the Reichert Award for Excellence in Advanced Laboratory Instruction. The award winner this year was Enrique Galvez, from Colgate University. The sudden announcement on Saturday February 29 that the March meeting was being cancelled came as a shock to many people, and it was a very bold move by APS – but in retrospect and in light of what has happened since then, it was very clearly the right move to make. Many meeting attendees (including myself) had to scramble to make new plans and figure out exit strategies, but everyone eventually got home, and for the most part, we have all been remaining at home ever since.
Following the cancellation of the March meeting, APS worked furiously on organizing a virtual platform for the April APS meeting, and the good news is that this meeting did take place as planned towards the end of April. At this meeting, FEd sponsored or co-sponsored seven invited sessions, and happily we were able to celebrate (albeit virtually) the winner of the Excellence in Physics Education Award, which was the Open Source Physics team. All of our scheduled invited sessions went off without a hitch, and the online attendance at these sessions was truly impressive. In the end, of course, we must gratefully acknowledge the heroic efforts of the APS staff for pulling the virtual April meeting together. Having served on the Program Committee for the March and April meetings this past year, I can say from direct experience that the tireless work of the APS staff made all the difference.
Other sessions planned by FEd have also been impacted, but have carried on (or will carry on) virtually. It has been our tradition to organize a special Physics Education session at the annual DAMOP meeting in June. In fact, this meeting did take place as an online event in early June, with a session entitled Quantum Quandries: How Can We Teach Quantum Mechanics Better, featuring invited speakers Carl Wieman, Chandralekha Singh, Enrique Galvez and Murray Holland. And finally, at the upcoming virtual AAPT Summer Meeting in July, we are sponsoring a special plenary session with Wolfgang Bauer speaking about green energy and Artemis Spyrou talking about nuclear physics and outreach at the Facility for Rare Isotope Beams (FRIB) located at Michigan State University.
During the APS April meeting, the FEd Executive Committee got together (online) for its annual business meeting and discussed various budgetary issues, in light of the fact that the bulk of our travel budget would remain unused this year due to major restrictions. We discussed several ways of putting our funds to good use during this particularly difficult period, and we came up with the idea of FEd Minigrants, which would be limited fund allocations to individuals or small groups who wanted to pursue a short-term project. The details of this solicitation were sent out to the entire FEd membership on June 9, so please check your e-mail inbox to find the details contained therein. If you have any questions, the person to contact is Laura Rios (firstname.lastname@example.org), who is our FEd Secretary/Treasurer. We have set three interim deadlines (June 22, July 20 and August 24), and so even if the first one has passed by the time you read this Newsletter, the other deadlines will still be open.
As always, we want to remind all of you that the Forum on Education sponsors two major APS awards, and we encourage members to consider nominating your worthy colleagues for such honors in the coming year. The two FEd awards have already been mentioned above, but just to list them explicitly, here they are:
In addition, FEd works closely with the APS Committee on Education (COE), and there are two other related awards/prizes that are under the purview of COE:
In addition, we hope that all of you will recognize and honor our most accomplished FEd members by nominating our worthy colleagues for APS Fellowship. We have a long line of distinguished FEd APS Fellows spanning the history of the Forum on Education, dating back to 1993. Please consider the efforts of your colleagues and the people that they have worked with to see if you know someone who is deserving of this recognition – and if so, please take a few minutes to begin the nomination process. You can find more information at the following website:
In the ongoing work of the FEd Executive Committee, I would like to mention that Catherine Crouch is leading the Program Committee for the March 2021 and April 2021 APS meetings, so if any of you have ideas or suggestions for education-related sessions at those meetings, please be sure to get in touch with Catherine. Also, Eric Brewe is heading the Nominations Committee this year, and he welcomes your recommendations for potential candidates for the leaders of the Forum on Education. This includes a new incoming Vice Chair, new Executive Committee members, and (for this coming year) a new Graduate Student representative. So please keep Eric in mind if you have any promising candidates to suggest to him.
Members of the FEd Executive Committee recently participated in a “brainstorming” session with the APS Committee on Education (COE) to explore issues pertaining to the recent push for online classes due to the global health situation and the possible inequities that can arise due to the pandemic. The discussion focused on how students have been impacted and the corresponding ramifications for student learning due to various demographic factors. This is an ongoing concern among educators across the country, and this is only the start of a much longer investigation. We welcome your input on this important subject, and on any other issues that are relevant to the imposed modifications in our educational pursuits.
In the ongoing cooperation between FEd and COE, one of the recent topics for discussion was put forward by Amy Flatten (APS Director of International Affairs). In November 2018, APS published a report from the Task Force on Expanding International Engagement (see link below).
Through this study, APS is hoping to find ways to enhance its international profile and strengthen international partnerships. Through the COE, we focused our conversation on how to increase educational connections extending outside the domestic domain. This could pertain to attracting new international members to APS, or solidifying pedagogical collaborations through Physics Education Research, or increasing educational connections around the world through attendance at education-related conferences or teacher exchanges in the U.S. or abroad. If any of you have had enlightening or transformative educational experiences with international institutions or collaborators, either here in the U.S. or abroad, please let us know!
Finally, on a lighter note, for those of you who read the monthly APS News thoroughly, the Forum on Education has been featured in the recent June issue. Each month, an APS unit is highlighted, and this month it was our turn to be in the spotlight. So check out the article in the June 2020 issue of APS News that just recently appeared. In case you have not been checking your office mailbox very often these days, here is a link to the article:
In the end, while we still endure the trials of this very unusual period and we learn to adapt our daily lives to what has been termed the “new normal,” we hope that you are all able to carry on and continue your professional activities related to research and teaching. As always, we welcome your input and your ideas to help further the mission of the Forum on Education. Here’s hoping that we will be able to meet again in person very soon and get back to business.Top
Catherine H. Crouch, FEd Chair-Elect and Program Committee Chair
We are eager to hear your ideas for Forum on Education-sponsored invited sessions at the American Physical Society’s March and April meetings! We are seeking ideas for sessions (and potential invited speakers) that would be interesting and beneficial to the members of the American Physical Society, particularly undergraduate and graduate students and early-career members, whether or not they are members of FEd. We encourage ideas for sessions that might be co-organized by another APS unit (https://www.aps.org/membership/units/) or the APS Committee on Minorities or Committee on the Status of Women in Physics, which also have the ability to organize sessions.
In addition, we are eager for your feedback on the ideas generated so far by the Program Committee, including ideas for speakers on these topics. Our current ideas include:
Either meeting (or possibly both):
Two of the sessions at the April meeting are co-organized with AAPT and the tentative plan is to offer one of those sessions on remote learning and one on some aspect of diversity, equity, and inclusion in physics education.
Please submit your ideas for sessions, as well as any input on the committee's ideas, to Catherine Crouch, APS FEd Chair-Elect and Program Chair for 2021, by email to email@example.com. Any ideas submitted will be considered by the Program Committee. The FEd is allocated a limited number of invited sessions at each meeting, based on FEd membership attendance at the previous year’s meeting, so we may have to postpone good ideas to a later year.
The deadline for session ideas and feedback is July 24.
FEd also sponsors contributed sessions at both these meetings, and APS members are permitted to contribute a talk or poster to the education sessions (using the physics education sorting categories) in addition to one on a technical physics topic. We invite you to consider contributing to one of these two meetings.Top

Many things have changed since our spring newsletter! The COVID-19 pandemic has significantly changed the way we live and work. During March many of us found ourselves thrust into “emergency remote teaching” with little or no training. The closure of schools and daycares have required parents (myself included) to juggle childcare responsibilities along with work. Conferences have been cancelled or converted to virtual meetings. More recently, events in the U.S. have brought issues of race and social justice to the forefront of our minds.
As we prepare for the uncertainty of the fall term, many instructors are wondering how to provide an inclusive, high-quality education experience for their students. In light of current events the focus of this newsletter is twofold: to highlight resources for teaching physics online and discuss important issues of diversity and systemic racism. The latter is addressed in the teacher preparation section edited by Alma Robinson.
I hope this newsletter inspires you to learn and grow as a physicist and physics educator. If you have ideas for future newsletter themes or an article you would like to contribute, please e-mail me at firstname.lastname@example.org. The deadline for the fall newsletter is October 1.Top

Many physics educators have had to make dramatic changes to their courses in March to convert them from face-to-face delivery to remote learning. For many faculty, this has been challenging since they only teach face-to-face with students and have no experience teaching remotely. Furthermore, many of our institutions have built success on close student-faculty interactions. This has left many faculty scrambling to provide a satisfactory learning experience for their students. The American Association of Physics Teachers (AAPT) and other physics and astronomy professional societies have shared resources to help physics educators during this challenging time. Below is a list of some of the most used resources.
PhysPort is a great source for ideas and resources that align with research-based pedagogical principles and research-validated resources for teaching online. It also has great ideas that can be use to make the online teaching process easier.
The Physics Teacher (TPT) and the American Journal of Physics (AJP) have compiled a collection of specialized articles that focus on remote learning. These articles highlight the use of smart phones for lab experiments as well as other activities that can be adapted for use by students at home. The articles have been made free to read, download and share for a limited time. https://publishing.aip.org/publications/journals/covid-19/aapt/
ComPADRE (the Physics Digital Library) has many different resources such as Open Source Physics, Interactive Video Vignettes, and computational materials for physics classes that can be used to teach courses remotely.
AAPT also has many discussion groups of active members and friends that allow the sharing of ideas, plans, activities, labs, lesson, etc. To join a discussion list use this link https://www.aapt.org/Resources/lists.cfm?_zs=1tmEW&_zl=AtR22
AAPT’s Committee on Physics in Two-Year Colleges has created a website that has many resources including grading papers online, taking good notes, remote clickers, recording classes or lectures using screen-capturing software, inserting quiz questions in the middle of presentations, and many more.
AAPT’s Digi Kits are vetted collections that include a hands-on, inquiry-driven activity inspired by articles from The Physics Teacher journal, digital resources that support student and teacher learning, and are aligned closely to the Framework for K-12 Science Education and NGSS performance expectations. Although these have been designed for K-12 physics educators, many can be used in higher education.
Physlets are over 800 ready-to-run interactive exercises for the teaching of the introductory physics sequence (kinematics through optics). This material uses a standard easy-to-understand interface designed with a sound use of pedagogy in mind.
PhET Interactive Simulations provides a collection of over 150 simulations, as well as sim-based lessons, labs and teacher resources. All are licensed as open (free) education resources. Tips for remote learning: See article in this newsletter
Interactive Lecture Demonstrations (ILDs) are a great active learning tool that students can use at home. ILDs are designed to enhance conceptual learning of physics lectures through active engagement of students in the learning process. ILDs consist of pictures, videos, displays and real physics simulations that are available to substitute for hands-on experiments. https://pages.uoregon.edu/sokoloff/HomeAdaptedILDs.html
PERbites is a resource available to the physics education community. The purpose of PERbites is to connect physics research in all areas and make the results of physics education research meaningful and accessible to all.
Diagnoser Tools is a coordinated and coherent suite of free online tools that teachers use with their students to scaffold and monitor the development of deep understanding in science. http://www.diagnoser.com
APS April Back Page is “Moving Physics Courses Online on Short Notice” by Chandralekha Singh. This article includes links to a number of different resources.
An article about physics smart phone apps
AAS has a website that lists a number of resources including AAS curated online teaching resources, community submitted online teaching resources, and Youtube videos on tools and tips of teaching astronomy online. https://aas.org/education/aas-responds-increased-online-instructional-needs
The American Sociological Association has a webinar on “Transitioning to Online Teaching in the Face of COVID-19” https://zoom.us/webinar/register/WN_Un66VwL8TjC2YTgWJ1JarQ

Due to the COVID-19 pandemic, many of us teaching physics as well as those teaching other subjects in face-to-face brick-and-mortar classrooms have suddenly found themselves in an unprecedented situation: the rest of the term should immediately transition to a completely online format! Here I outline some strategies and resources that can help you and your colleagues in such a situation who have not had extensive time to think or plan for online instruction. It is important to recognize that everyone, including you and your students, is anxious and stressed by the circumstances, so being compassionate to yourself and your students is of paramount importance. I cannot emphasize enough that providing maximum flexibility to students is critical, particularly because they did not sign up for an online course and many of them may not have necessary resources, e.g., access to a computer with reliable internet connection or a quiet room at home or required time due to being sick or caring for a sick family member in order to complete all of the requirements of your online course. Everyone is trying to do their very best to salvage the situation, so whatever you and your students can accomplish is good. Communicating frequently and clearly with students is key.
There are many online resources, for example, Linda Strubbe and Sam McKagan’s excellent crowd-sourced resources on PhysPort , that can be invaluable so you should definitely go over it in its entirety. Below, I summarize seven things to keep in mind while preparing for and executing your online physics courses, including labs:

Over many years, our physics education community has been creating, studying, and adopting new pedagogies to improve our students’ experience and learning of physics. From Peer Instruction to Interactive Lecture Demos to Tutorials in Physics, we’ve increasingly used active-learning techniques, promoted making sense of concepts, and engaged students in science practices and ways of thinking. This spring, as schools transitioned to remote learning, we have all faced the challenge of how to continue to actively engage students and address this broad set of learning goals. This fall, we will again be facing a good dose of remote learning.
From lecture to lab, interactive simulations are highly flexible tools that can support your transition to remote teaching and keep learning active. Since 2002, our PhET Interactive Simulations project at the University of Colorado Boulder has created 106 interactive simulations for teaching and learning physics, all open (free) educational resources which cover introductory physics, quantum, and some upper-division topics. Each PhET simulation creates an intuitive, game-like environment where students can learn through exploration, where dynamic visual representations build understanding, and where science and math concepts are connected to the real world. Many include measurement tools for data collection. With this open design approach, interactive simulations can be used in just about any part of a course, by the teacher or the students, synchronously or asynchronously, including pre-lab and lab activities, clicker questions, interactive lecture demonstrations, homework assignments, tutorials, pre-class just-in-time-teaching activity, etc.
This spring, as learning moved online, our team worked to support educators’ needs with new resources and capabilities. Visit the PhET website now and find:
For remote live lecture or lecture capture, many simulations can serve the role of your traditional lecture demonstration equipment (waves, springs, projectiles, pendulums, circuits, etc.), and go well beyond, with options to show the invisible, layer on multiple representations, and modify hard-to-change parameters (like altitude). To infuse active learning, you can use simulation-based clicker questions or interactive lecture demonstrations, or engage students in more open whole-class inquiry. And with every student necessarily on a device, you can chat a link to a simulation and invite students to experiment with the simulation in class, and then share their screen and use the simulation to provide evidence in support of their reasoning. For larger classes, you can add short 5- to 10-minute experimentation sessions using breakout rooms where groups of 3-4 students collaborate on exploring a simulation. These student groups can complete a sim-based challenge question and record their observations, evidence, reasoning, and sim screenshots in a shared Google doc.
For physics labs and activities, simulations offer an opportunity to engage students in science practices – designing experiments, collecting, analyzing, and interpreting data, building mathematical models, justifying claims with evidence, and so on. Students can complete sim-based labs on their own from home, or better yet, work collaboratively with lab partners sharing screens online, e.g. in a Zoom breakout room. While many on the PhET team are experimentalists and value students working with real equipment, gaining experience with experimental and measurement uncertainty, and debugging and problem solving in experimental systems, simulations offer significant learning opportunities for the lab. Simulations create inviting, open, and exploratory environments; environments that enable student agency and rapid trials, visualize the conceptual models experts use to help their understanding (e.g. current, vectors, charges, particles, fields, etc.), and support qualitative and quantitative data collection. An early research study found that students who first learn using our Circuit Construction Kit simulation perform better at building and explaining a circuit using real equipment, compared to students who learned using the real equipment . In working with the simulation, students benefit from the immediate cause-and-effect feedback to their interaction, the visualization of electron flow or current, and the ability to support multiple, rapid trials – all supporting the development of their conceptual model that they can then apply to building with real equipment.
Many of our newer HTML5 simulations have new screens and additional measurement opportunities. The Projectile Motion sim has a new data probe for capturing height, range, and time data. The Gas Properties sim has a new tool to measure wall collisions and a new screen for Ideal Gas Law measurements. The new Diffusion sim can be used to measure diffusion times vs a wide variety of properties. The Energy Skate Park prototype sim offers new Measure and Graph screens. The Wave Interference sim can be used to conduct the double-slit experiment. The list is long. If real experimental equipment or videos of real equipment are available, combining simulations and real equipment can also make for a great learning environment.
In crafting student labs and activities for remote learning, we offer a few recommendations to help scaffold your lesson and maintain student inquiry. First, begin with a short (5-10 minutes) of open play and exploration and have students record a few of their discoveries and observations. This approach promotes student agency, allowing them to become familiar with the simulation and mimics the broad exploration scientists will do as they explore the parameter space of a system. When designing the lab, maintain student inquiry by using challenge questions – as opposed to detailed directions – to create a structure that requires experimentation, data collection and analysis, but in ways that leverage the existing scaffolding in the simulation and continue to provide agency to students. Within the activity, open table structures and screenshots are good ways to provide some scaffolding for students working alone. And, if you are using an HTML5 sim, consider using the “?screens=” parameter on the end of your URL to start a PhET sim constrained to run just the screen(s) you want.
As you plan your simulation use, you need to be aware of the device compatibility of the simulation. Any of our HTML5 simulations will run on any device from full computers to Chromebooks to tablets and smartphones, supporting teacher use as well as student assignments. HTML5 simulations are also easily embeddable in any webpage and many homework systems. While we continue working to bring all PhET simulations to HTML5, over 60 legacy physics simulations still only exist in Java or Flash. If you are using simulations for teacher-led demos or discussions, we recommend using the Java and Flash versions on a full computer for best performance. The “Java via CheerpJ” sims can be assigned to students. Flash runs for now but Adobe is sunsetting the technology at the end of 2020. We are working to convert our simulations to HTML5, which is a resource and funding intensive activity.
As we face the teaching challenges of these times, we encourage you to join the PhET community and stay connected. If you are new to PhET, we invite you to visit the PhET website and explore the physics simulations. If you are already using PhET, we invite you to register for a free account and share your lessons and labs with other educators. If you are working on creating PhET labs this summer, we invite you to express your interest here; we will be connecting educators with shared needs and goals to each other for summer work.
Finally, we love to hear from our user community. We invite you to join the conversation on Twitter (@PhETsims). And if you want to report a bug, share an idea for a new simulation or an improvement, or just seek technical support, you can contact us at email@example.com.

As classes quickly moved online during Spring 2020, students, staff, and faculty in all types of institutions, at all levels, found themselves adapting to novel online learning spaces. Those who incorporate active learning in their classes, encourage group work, and promote conceptual sense making to engage communities of learners needed to be reflective, thoughtful, and creative in constructing these new spaces. The Learning Assistant Alliance (LAA) recognized that undergraduate Learning Assistants (LAs) were immediately providing crucial support for faculty and students in these new spaces, and leveraged its Alliance member expertise to develop a set of resources to assist in LA supported classes (https://sites.google.com/view/laa-elearning/).
LAs support student learning and persistence by engaging students and facilitating active learning and group work in many learning contexts. LAs, as key players of an instructional team, can play collaborative roles in identifying how we teach our courses, bringing in unique perspectives on what works and what does not work for their near peers. When LAs take on these leadership roles, they develop identity as science people, and the classes we offer improve along multiple dimensions - they become more supportive and interactive and better leverage student strengths and address student needs.
During the Spring 2020 term, LAs took on new collaborative roles and additional responsibilities as a result of moving online. To support the education community in using their LAs effectively in these new spaces, the University of Colorado Boulder and the LAA organized a series of Virtual LA Panels where the community could hear from experts: the LAs doing this work around the country. The LA panels were moderated by LAs and featured LAs from the humanities, social sciences, and science and math from Chicago State University, the University of Colorado Boulder, the University of Colorado Denver, Colorado State University, the Community College of Denver, Florida Atlantic University, Front Range Community College, Metropolitan State University of Denver, Montgomery College, and San José State University. This broad representation of colleges and disciplines provided a unique perspective on how LAs around the country were supporting their peers (https://sites.google.com/view/laa-elearning/virtual-la-panels).
The national LAA LA Panel, held on April 16th, had about 70 participants from institutions around the world, in addition to our panelists. Three additional panels were held in April at institutions across Colorado, with an additional 55 participants. The community of panelists and participants provided both overarching ideas and specific techniques to effectively support students remotely.
Additionally, to learn more about the perspective of faculty working with LAs during the transition to remote learning, faculty at the University of Colorado (CU) Boulder were surveyed at the end of Spring 2020 and provided useful insight on the impact of LAs.
Keeping the community of learners engaged
While navigating this new space was challenging, there were elements that kept the LAs engaged in their work of supporting students. LA Diane Hogan cited the importance of ongoing interactions where students reached out to her with questions: “It lets me know that they are still willing to learn, and it makes me feel - being in this situation, it shows me that no one has given up.” LA Linnea Wolniewicz mentioned that “something that has really helped me feel like I'm still part of the online classroom community is when I attend classes and everybody has their video on. It's like you're still attending the same lecture with the same people that you were before, and you might not be sitting next to them, but they're still there on the screen.”
LAs cited the importance of checking in with students to see how they were doing. LA Siya Bedi mentioned “... one thing I've been trying … is … starting off by asking the students as an LA, something unrelated to the problem. So something like, ‘how are you doing?’ or how their day's going, so they feel more connected, and it's an easier transition to start a discussion.”
LAs are a key source of student support, both academically as well as socially, during challenging times. One faculty member expressed in the Spring 2020 faculty survey, “The most valuable thing this semester is having the LAs continue their work during remote learning … They are really leading by example and giving students the message, ‘hang in there, you can do it!’” Similarly, another faculty member shared, “As always, [LAs] are an approachable peer for students in the class, especially under stressful conditions.”
Providing support and facilitating active engagement
LAs took on many roles during remote classes, including facilitating recitation sessions, holding office hours, facilitating discussions during synchronous lecture time with the faculty (in features such as chat and breakout rooms), as well as in promoting engagement in asynchronous discussions.
Three of the LAs, Linnea, Benjamin Tressler, and Nicholas Pizzo mentioned that more students were taking advantage of office hours and were being more “communicative.” Benjamin stated that “one positive thing of the transition to online learning is just being more available, in the sense that people can just join office hours or whatever they need in the comfort of their homes.” Online office hours via video conferencing at times that accommodate the complex schedules of our students can encourage more participation in these spaces. For some LAs, using video conferencing is new and provided some benefits that they did not have before through email communication. LA An Dang mentioned “I think [Zoom is a] super helpful tool, and it should be used as much as possible ... it's helpful to see and show the students how to do problems ... even when I'm at home ... it's very interactive - it's not like just through emails or through text messages.”
LAs described the challenges of active engagement and group work in these settings but offered suggestions. Many LAs engaged with groups in Zoom breakout rooms. During group work, having a dedicated group member as the “screensharer,” a new role in this setting, proved to be important to keep groups focused on a task. Group roles seem to take on additional importance in these settings. Nicholas mentioned how LAs used the WebEx whiteboard and chat features. “For our live lectures - at the second half of the lecture when the LAs are interacting with students while one of us is physically working on the whiteboard answering questions about problems and using their mic, the other two LAs in the class are answering questions in the chat.” Chat features in video conferencing provide a unique space for LAs to support students as an instructor is discussing a particular topic. Responses by LAs in real time can help students not get lost during a lecture and keep them engaged. This is especially important in an online space where it can be more challenging to read the room.
When faculty at CU Boulder were asked how they thought the transition to online learning would have differed if they did not have LAs, faculty said that “Our students would have been less supported … and likely would have learned less” and “class would be less personal.” An instructor of a large introductory course shared, “The LAs are absolutely critical … Without the LAs, I think we would have seen more student frustration about continuing to do active learning work during lecture.” Several faculty also expressed that without LAs, smaller group discussions would have been challenging, because, as one faculty member stated, they “would have not been able to do class breakout sessions.” Faculty valued LA input and feedback on how to promote student learning in a remote setting, such as improving student interaction in Zoom and providing “suggestions for making discussions in breakout rooms more engaging.”
Facilitating technology adoption
In many classes, LAs supported the new technology needs of the course by helping faculty and students navigate new communication infrastructure. An mentioned, “Since it's not like a face-to-face class anymore, it might take more time for professors to respond to us through emails. And we overcome that by using GroupMe, which is like a chat service.” Diane, a computer science major, used her computer skills and discussed how she was able to help students set up their online classes: “I help them go through the platform that they need to use to get to classes - so it's very positive for me because I am helping them with something that I already know.”
Providing perspectives as students in remote learning settings
During the panels, LAs were able to provide both a learner perspective as well as an LA perspective. They understood the challenges of studying at home and staying focused and motivated and could often better relate to the experiences of their peers and convey this to instructors over the semester. Faculty valued the LA’s unique student perspective and “appreciated [LA] feedback about how students are experiencing the transition.”
Many students rely on college and university learning spaces to do their work. LA Bailey Holifield said, “One challenge is finding somewhere quiet to do my work. I have to sit down and be motivated, and it's hard for me to do that by myself sometimes.” Diane mentioned that “most students that I have agree with me -- it's the distractions at home … you have TV to watch, we got the kids, we got the dog, family members … it's a challenge mentally to not be in a learning environment.” LAs are often in better positions to empathize with the students in these classes and what they might be struggling with in these new spaces.
Although LAs cited the importance of synchronous interactions in providing community and some sense of normalcy in these spaces, they also provided a student perspective on issues of access, citing the importance of also providing asynchronous materials. Asynchronous materials provide students the opportunity to review materials and also mitigate certain circumstances that students faced during the semester. For example, Benjamin said, “I have a 10-hour time difference. I traveled back home … So there's some lectures that I have that end at 4am, and well, that's not that's not nice when you live with your family. And so there are classes where …[I] wake up in the morning and watch the recorded lecture of what happened at 4am … and that's why making it an asynchronous activity gives the opportunity for students who couldn't appear in person or online to do it in their own time.” LA Kyle Tayman also commented on the value of recorded lectures:“say you know you missed something that the professor said, instead of just being lost for the rest of the lecture, you can just rewind it”
Many institutions are now developing plans for remote learning or hybrid spaces for the Fall 2020 semester. While the situation with COVID-19 remains challenging for students, LAs, staff, and faculty, there are lessons learned from our LAs that we can take into Fall 2020 and beyond. Aidan Barker, the LA Panel Moderator and LA at CU Boulder, challenged the LAs to describe what they have learned from this experience - items that they see as useful in remote learning and in in-person settings.
LAs found that the virtual videoconferencing format, at flexible times, allowed for interactive opportunities with students that may not have occurred in a face-to-face setting. As we transition back to in-person coursework, classes might also provide virtual spaces for discussion, such as sessions that can be implemented via Zoom breakout rooms. These can happen at times convenient for students, such as the evenings, with LAs moderating the sessions.
Creating personal connections with students was also highlighted as an important feature that should continue regardless of the instructional setting. Benjamin mentioned that “a good thing would be for professors to maintain a kind of personal relationship with students … try and get to know them a bit, maybe kind of personally invest in students a bit more, as you are in online classes … I'm sure students would appreciate to see that more once we get back to classes.” He went on to say “I'm sure we'd all like to see a bit of personal connection between a mentor, a professor, and the student.”
LAs also felt that the sense of flexibility and accommodation should also move forward as we transition back to more traditional learning spaces. Linnea commented that “I think it's wonderful that faculty are being more understanding of the extenuating circumstances, and things like that, and like deadlines, and it would be wonderful if we could carry that sense of connectedness and, like, caring for each other beyond the classroom.” An mentioned that she was proud of her institution for its diverse support of students, stating that her institution “has been helping us with, like, emergency aids, and renting out laptops without fees, so that's one very big support from our college, and I am very ...proud..” LAs on the panels cite the importance and attention to empathy and compassion continuing beyond COVID-19. These statements echo what Valerie Otero describes on how LAs are “leading the charge of creating meaningful, compassionate online experiences for students during the COVID-19 crisis.”
As we move forward, LA Gabrielle Jones Hall reminded the participants attending the virtual LA Panel to “take this abrupt transition as a wake-up call - really pay attention to STEM education research … learn about pedagogy, take Learning Assistants serious, because we're here to help.”

Physics, as a discipline, continues to suffer from an underrepresentation of traditionally marginalized groups. This issue of the Teacher Preparation Section discusses ways that we, as educators of future physicists and physics teachers, can help to address this lack of diversity. Although the following articles had already been planned to be published in the Summer 2020 newsletter, the recent murders of George Floyd, Breonna Taylor, Ahmaud Arbery, Dominique “Rem’mie” Fells, Riah Milton, among others, alongside the ensuing public outrage have made the neccesity for all of us to combat systemic racism even more urgent.
Danny Doucette and Johan Tabora describe the Underrepresentation Curriculum, a collection of lessons, with accompanying teacher guides, that has students engage in conversations about inclusion and equity in physics. The lessons are organized in a modular fashion, giving instructors (ranging from middle school to college) the ability to adopt a lesson, a unit, or multiple units to fit their particular needs.
Eleanor Close and Xandria Quichocho illustrate how the Physics Learning Assistant (LA) Program at Texas State University has been successful in fostering positive physics identities among the LAs. By normalizing mistakes and having the LAs help each other during the LA Prep meetings, the LAs develop a deeper understanding of physics and an increased confidence in their physics ability.Top
Danny Doucette and Johan Tabora
When we were asked last month to write about the Underrepresentation Curriculum for the FEd newsletter, we were honored and excited to share our approach to teaching about systemic racism in physics classes. Since then, the murders of George Floyd, Breonna Taylor, Ahmaud Arbery and others have provoked such a strong and urgent national response that talking about racial justice in physics class has become both inevitable and necessary. Black lives matter. As educators, we strongly decry the endemic systemic racism and white supremacy that have continually oppressed Black lives and commit to uprooting these discriminatory structures through our teaching.
For teachers who need resources to have conversations about systemic racism and other systemic social injustices in the classroom tomorrow, we have some recommendations. On the other hand, if you are looking to incorporate anti-racist pedagogy into your science curriculum, we offer to you the Underrepresentation Curriculum.
In “A Framework for K-12 Science Education”, the National Research Council calls for concerns about equity to be placed at the forefront of our efforts to develop and deliver science instruction in the 21st century. In past newsletters, articles in the FEd Teacher Preparation Section have addressed how instructors can adopt inclusive teaching practices that address curricular topics, like multiple representations and sense-making, as well as socio-cultural aspects of education like identity, belonging, and affect. This article introduces a complementary approach that seeks to help students understand the nature of essential social issues as they pertain to science by examining the underrepresentation of racial, ethnic, gender, and other social groups in physics. Underrepresentation acts as the starting point for the curriculum, which uses discussions, reflections, and other activities to help students learn about the importance and complicated reality of equity and inclusion in both physics and the modern world, while also helping students better understand themselves and their own various identities.
The Underrepresentation Curriculum builds on more than a decade of development by physics teacher Moses Rifkin and others. A team of volunteer high school and college educators develops and refines curriculum modules, runs workshops, cultivates resources and community, and conducts research on the curriculum. Over time, the curriculum has been adopted and used by middle school, high school, and college teachers around the world.
The curriculum starts by asking students to do a bit of research about the life of a physicist from a traditionally marginalized group. This leads to the question that will guide our discussions, supported by historical data from APS and AIP: “Why are there so few Black (or women, or Latinx, or LGBT, or disabled) physicists?” Students tackle this question using scientific tools and modes of thought: proposing hypotheses and seeking falsifying evidence, obtaining and plotting data, developing explanatory models, and negotiating understandings collaboratively with their peers. Along the way, we ask students to attend to an assumption that lies at the heart of scientific practice: is science objective, subjective, or somewhere in between? They also seek to answer the question posed by Chief Justice Roberts, “What unique perspective does a minority student bring to a physics class?” By studying topics that involve the intersection of social issues and science, students not only realize the utility of the relevant scientific skills they have already developed, but also come to appreciate the interwoven nature of society and science.
After this introduction to key topics, teachers who use the Underrepresentation Curriculum choose from a variety of specific topics to explore next, including stereotype threat, meritocracy, systemic racism/sexism, racial privilege, implicit bias, intersectionality, and the concept of a model minority. For each, the curriculum provides a flexible set of activities and prompts for guided reflection. The curriculum wraps up by calling on students to take action based on what they’ve learned. In the past, students have embraced this opportunity by creating posters, podcasts, videos, reflective texts, poetry, songs, or other forms of expression, and also by going out into their schools and communities to learn more.
The first question we always hear when we explain the curriculum is, “when do you have time for all that?” It’s a fair question. As educators, the editors of the Underrepresentation Curriculum are intimately familiar with the time pressure associated with teaching in a high school or college. We wrote the curriculum to be flexible: a brief implementation can be done in as little as 90 minutes, or a full course of study can productively fill two weeks of classes. Some instructors implement the Underrepresentation Curriculum during the last class before winter break, following AP exams, during the class after a difficult assessment, or dispersed throughout the year. The curriculum is most effective after teachers have had an opportunity to establish norms and develop a community of respect in their classrooms. Being able to have respectful, productive discussions is an essential prerequisite to teaching the Underrepresentation Curriculum since much of the curriculum is built on small and large group discussions around sensitive topics.
Talking with students about race, gender, disability, or other social issues can be intimidating. For that reason, the Underrepresentation Curriculum is flexible enough to be adapted to a variety of different settings and implementations. There is scope for instructors to discuss their own experiences, welcome the voices of outside experts (or experts within the classroom), or simply rely on well-articulated perspectives from readings. In general, teachers who use the Underrepresentation Curriculum tend to acknowledge their own identity and potential biases and then focus on promoting productive and respectful discussions amongst students, acting as a guide rather than an authority. The goal is to help students learn how to frame and talk about these issues in an engaged and productive way, not to advocate for any particular political opinion. Rather than adopt a “both sides” approach, we encourage students to consider as broad a range of perspectives as possible, including those that may be unfamiliar to them.
The response from students has been powerful. They quickly see that “there’s really no class that would be better to talk about [equity],” and that “our race affects almost every aspect of our lives.” Following the curriculum, students are less likely to view science as a strictly objective enterprise, more likely to describe their race as important to their lives, and more likely to believe that equity is important in science.
If you work with future physics teachers, or if you are a physics instructor yourself, and would like to take a look at the Underrepresentation Curriculum, visit our website at underrep.com. We are currently asking that new users fill out a short survey before accessing the curriculum materials so we can understand who is using the curriculum, provide support and community, and track our impact. For some background on the curriculum, and discussion of its positive impact on students, papers by Moses Rifkin and Abigail Daane and collaborators explain how the curriculum has been implemented at the high school and college levels. Abigail Daane has also published research on the impact of the curriculum on college learners. We welcome correspondence at firstname.lastname@example.org, and look forward to hearing from you!

Eleanor Close and Xandria Quichocho, Texas State University
Physics lags almost all other STEM disciplines in our lack of diversity. Gendered and racialized stereotypes of physicists as brilliant geniuses permeate American culture and create barriers for many students before their first physics course. To counter these enculturated biases, we are working to create a department culture that supports collaborative student community, recognizes many different strengths as valuable, and acknowledges and addresses bias. In the physics department at Texas State University, we have created a Learning Assistant (LA) Program with structures specifically designed to promote inclusive community among students. In this article we will describe some specific elements of our LA Program and share some of our research on how participation in the program impacts our LAs.
In the LA Model, undergraduate LAs meet weekly with faculty to prepare for instruction. In our implementation, all LAs and LA-supported faculty meet together each week, creating opportunities for students to get to know each other and to meet faculty in an informal setting. One of the community norms we promote is that LAs will continue to learn physics as they prepare for and assist in the introductory courses. This also means we expect LAs to make mistakes while working through material in weekly LA Prep meetings, and we work to normalize this. During LA Prep, we discuss ways of supporting student learning as well as identify the content we hope they will learn, and we encourage LAs to share their own struggles with the material as guidance for what to expect in the classroom.
As part of an ongoing study of physics identity development, we collect video data during LA Prep. These videos can give us insight into the kinds of discourse LAs engage in with each other, and the community norms they express and enact. In our analysis of these episodes, we find that discussions about teaching often merge seamlessly into new content learning for LAs. For example, in a preparation session early in the semester, Dustin (pseudonym), a new LA in introductory mechanics, asks the experienced LAs at his table how to explain a concept to students:
So how would you explain, though, ... “how is the direction of the change of velocity vector related to the direction.” Like, I know they’re the same, I’m just trying to figure out how I would explain that to them. Other than just be, like, “it just is.”
Ava, a physics major in her third semester of LAing, walks through an explanation using the equation for average acceleration. At the end of her explanation, Dustin responds: “That makes sense. … I’m probably going to get more out of that than any student would ...I’ve already learned a lot more than I thought I would.” Beau, a second-semester LA, replies “Oh, you learn SO much more doing this.” No one in the group seems either surprised or disconcerted that Dustin is learning more physics as they are preparing for the next week’s class; in fact, Beau affirms that this is a valued part of the experience.
The experienced LAs preparing with Dustin are not only able to help him better understand the physics concept at hand; they’re also reinforcing the idea that the practice of learning physics is more than immediately finding the right answer. Using a theoretical framework drawn from Communities of Practice and Physics Identity, we understand these interactions as both providing recognition to the experienced LAs and creating a body of shared experience that can support a sense of community membership. The community practice of valuing and affirming ongoing physics learning also reinforces the idea that it is “okay to be wrong”, which challenges the idea of physicists being natural geniuses and creates a more accessible and accepting environment.
This environment has helped students from multiple minoritized groups gain confidence in their physics knowledge and reconcile their multiple identities. In another research project, we use intersectionality1, , , body performance, and the Critical Physics Identity framework as lenses to understand the personal narratives of women of color and LGBTQ+ women who study physics. Many of the women interviewed had participated in the LA program, and describe it as an important factor contributing to their success during their studies.
For example, one interviewee—Nadya, who identifies herself as a Guatemalan, White, and straight woman—told us how being an LA helped her build her confidence. In response to the question “Do you see yourself as a physics person or a physicist?” Nadya first described how her answer to that question had changed over her time as a student, then reflected on what helped her develop her identity as a physicist:
...even doing Pedagogy- like that helped to- becoming in L.A., oh my God, that helped me so much with gaining my confidence—because I really lacked confidence in my skills, because I just didn't- I didn't do well in intro levels, because I was just so, like, not focused [on] school and I was going through a hard time. But, um, it- being an L.A. made me more confident in myself, and ... it helped me define how I see myself as a physicist—and how I can be able to say like, "I'm a physicist."
Nadya’s response shows that the community practices and norms of the LA Program not only support collaboration and continued learning, but also, through these, opportunities to gain competence in physics content and strengthen physics identity.
Nadya and other interviewees often talk about the LA Pedagogy course (required of all first-time LAs) and its impact on their physics experience. At Texas State this course is an upper-division physics elective, described by another interviewee, Autumn, as a “crash course on...how you learn.” Autumn identifies herself as a White and bisexual woman. This piece of Autumn’s narrative was part of her response to the interviewer’s question “How did you get into physics?” which generated the follow-up question “Can you talk about that, the psychological educational aspect of the department?” Autumn replied:
I feel really strongly that I wouldn't have done as well, or as been as successful ...at a different university that doesn't do the LAs or- doesn't have the kind of supportive, um - like, all the professors are on your side... I just feel like the kind of person that I am is that I am really shy and timid and have a lot of fear of failure. So being in an environment where it was kinda- maybe more cut-throat—I feel like that might affect me more than somewhere like here. And the fact that they pretty much give you a crash course of what, how you learn, and the psychology behind that. And I think that really opens your mind up to- to kind of believing in yourself.
In a program with a more competitive environment, Autumn’s “fear of failure” might have been a stumbling block towards development of positive physics identity. However, in her physics community with practices that normalize making mistakes and prioritize collaboration and continued learning, Autumn was supported and encouraged to embrace the “wrong” ideas as a tool for learning and to work with her peers to develop a deeper understanding of the material.
Our LA program creates an inclusive environment in ways both planned and emergent. We hope this description of the structures that have proven successful for supporting our students will help other departments discover new ways to foster inclusion.

On page 113 of the same issue, Georgios Horsch compares theory and experiment for the flow of water out of a hole in the side of a vessel including corrections for the size and shape of the orifice, and on page 119 Marc Frodyma compares motion due to a constant force in Newtonian and relativistic mechanics. In the March issue, I took note of a thermodynamic study of air in a vacuum food cylinder on page 186, and a short look at why a nearly empty shampoo bottle is so much easier to knock over than a full one on page 220. Vincent Coletta on page 244 of the April issue shows that students choose to sleep longer before final exams when shown data that doing so improves scores. Finally, a comprehensive experimental study of how a handblender immersed in a glass of water can be used to lift it is reported on page 308 of the May issue and corrects my previous hypothesis about the effect. Much of the May issue is devoted to articles dealing with gender issues in physics education.

The October–December 2019 issue of Physics Education (India) at http://www.physedu.in/ has an article discussing the possibilities for interstellar travel. After reviewing the history of space exploration, relativistic acceleration, and the rocket equation, various concepts are proposed such as chemical, nuclear, anti-matter, hydrogen scoop, solar sail, particle beam, and bomb propulsion mechanisms.
The wanderings of earth’s magnetic poles are discussed on page 363 of the March 2020 issue of Resonance. Using the angle of minimum deviation to measure refractive index is reviewed on page 579 of the April issue. These articles can be freely accessed at http://www.ias.ac.in/listing/issues/reso.

Article 013101 at https://journals.aps.org/prper/pdf/10.1103/PhysRevPhysEducRes.16.013101 suggests that students may learn more from online than live lecture demonstrations, in part because contrasting cases can be quickly shown back-to-back, slow motion is more easily displayed, and whiteboarding explanations can be presented and animated.
