Physics in the 21st century will be marked by these 5 characteristics. -Active Engagement -Embedded Science Practices -Continuous, Personalized Feedback -Unrestricted Exploration of Phenomena -Multi-modal (Face-to-face an non-face-to-face) What are the barriers that prevent so many of us physics teachers from achieving these ideals? How can we overcome those barriers?

technical paper

When our university imposed strict social distancing restraints in response to the pandemic, I developed a technique to offer introductory physics labs at our two-year access campus, whereby exactly one student per lab team actually came to the lab room and operated the equipment, and the remaining team members joined remotely. All team members worked together in real time using a shared Google Sheet, while simultaneously viewing the apparatus and communicating with one another through Zoom. I assigned POGIL-style roles to foster authentic collaboration and work balance within each team (and checked the Sheet's edit history afterward to be sure). In this talk, I describe the implementation details and technological challenges of this technique; outline its post-pandemic continuation as a student accommodation mechanism; and explore its potential as an alternative to "bootcamp" labs for "mostly-online" lab course delivery.

Blended Lab Teams: From Pandemic "hack" to Online Innovation

We have developed a new learning format to reach students around the world during the pandemic: virtual and interactive learning units. They consist of a unique combination of pre-recorded explanatory videos, interactive elements such as quizzes, screen experiments, and expert interviews. We consider interactive learning units to be very promising for incorporation into remote, blended, and face-to-face teaching and learning of physics. In this contribution, we present an interactive learning unit about Positron-Emission-Tomography created with H5P (cern.ch/petworkshop). PET is one application of particle physics in medical diagnostics, whereby particle detectors are used, for example, to locate a tumor. Empirical studies have shown that medical applications of physics are particularly interesting for students. We highlight the main components of the interactive learning unit about PET and provide ideas how to use the material in your physics lessons.

When the pandemic forced most of us online, many teachers made use of their college’s Learning Management System. However, I have always found such systems to be slow and laggy, requiring way too many steps to update, and thus almost unusable to my ADHD brain. It was even more challenging during my wandering adjunct days when I might be teaching at multiple schools with their own systems and setups. Fortunately, I have dabbled in web development and was able to come up with an alternative. In this presentation I will describe some of the tools and practices I have created to replace the LMS with something more efficient for myself and my students alike.

Replacing the LMS as an ADHD Professor and Web Developer

I was fortunate to meet Curt Hieggelke almost 30 years ago when I was a research physicist looking to get hired as an adjunct. I eventually became Curt's full-time colleague at Joliet Junior College. In addition to his well-known national work that others will focus on, Curt cared deeply about Joliet Junior College and the local AAPT Sections (Illinois Section, Chicago Section). Curt made a huge difference at the college where among other things he served at various times as a department chair, president of the faculty union, and an influential voice on any committee that involved technology at the college. Curt also was very involved in the Illinois Section where he served as an officer, meeting host, and seemingly permanent member of the executive council. My talk will focus on Curt's local accomplishments.

Imagine your students working together on an activity that engages them with authentic data, is aligned with topics you already teach, and builds their confidence in doing science, while becoming more data fluent. Rubin Observatory has developed free, online investigations that use intuitive data visualizations and interactive analysis tools. Investigations are designed to take into account classroom time and technology constraints, and address the reasoning levels and common learning challenges of students. While they can be used asynchronously, a face to face setting is optimal for active-learning and discussion. These investigations are appropriate for students in advanced middle school through “Astro 101” college courses. They are accessible to students of all backgrounds and abilities. All investigations incorporate the three-dimensional learning design of the NGSS and come with extensive teacher support materials, including formative and summative assessments.

In this talk, I will present a methodical (step by step) spatial curriculum focused on teaching students about the complex astronomy concept of seasons. The curriculum teaches students about seasons using spatial activities to improve their spatial thinking, reasoning, and conceptual understanding of the topic. This spatial curriculum requires minimum material and is easy to implement for middle or high school students. The curriculum was implemented in 6th grade at a STEM school. The 7-lesson plan curriculum includes spatial components like 2D and 3D drawings, videos, and simulations combined with group discussions. Students use digital diaries (Google Slides) as means for journaling and learning about various concepts related to the seasons. The implementation showed that spatial activity improved students’ spatial thinking and reasoning. Students also demonstrated an overall increase in conceptual understandings about seasons and showed more interest in learning new astronomy topics using a similar spatial curriculum.

ACORN Physics (“Attending to Conceptual Resources in Physics”) Tutorials are a part of a broader effort to understand and cultivate the wonderful ideas that students use as they learn physics. These tutorials are designed to help instructors pay attention to and build from students’ common, fruitful ideas (“ conceptual resources”) that represent seeds of science. We have done research to identify conceptual resources that students use as they learn about kinematics, linear momentum, forces, circuits, mechanical waves, and heat and temperature -- so that we can bring you tutorials that elicit and build from student resources and provide you with pragmatic support to implement these tutorials. You can access all of our materials, including the tutorials, videos of students using them, questions to help you prepare to use them, conceptual questions that you can build in to your curriculum, and overviews of our research, free from our website at https://www.physport.org/curricula/ACORN

Communicating physics is an essential learning outcome for undergraduate physics courses because it facilitates the synthesis of students’ ideas, is a useful professional skill, and is the basis of sharing knowledge with a broader community. Physics lab courses are an ideal setting to learn these communication skills. Writing is an important subset of communicating physics, which has been explored in the “Framework of Goals for Writing in Physics Lab Classes” from Hoehn and Lewandowski. The overall goal of this project is to use this framework to understand how students acquire writing skills in physics, to structure labs to support learning those skills, and to measure the effectiveness of scaffolding writing skills into the lab sequence. At our institution, we are restructuring the lab sequence to scaffold writing skills. We collected and analyzed student writing samples and open response feedback surveys and will present preliminary results.

Scaffolding Writing in Physics Labs

Instructional explanations (hereafter explanations) are ubiquitous in all classroom formats in introductory physics. While there is a large body of work exploring the range of strategies that are employed in explanations and their effect on learning, not much is known about the relationship between student preferences for certain explanation strategies and the strategies that are known to be effective. We claim this is important to understand, as student preferences will influence perceptions of instructor efficacy and learning regardless of student learning outcomes. To explore this relationship, we asked first-year engineering students in a large enrollment introductory physics course to compare pairs of explanations generated by highly regarded instructors (including undergraduate learning assistants, graduate teaching assistants, and faculty) and describe the criteria they used to determine which explanation was better. We conclude with commentary about the need to balance student preference with explanation qualities known to positively impact student learning outcomes.

Covariational reasoning--considering how changes in one quantity affect another, related quantity--is a foundation of quantitative modeling in physics, and a learning objective of introductory physics instruction at the college level. Our prior work suggests that covariational reasoning in physics contexts differs from that in purely mathematical contexts, and is effortful even for well-prepared students. We also find that students' covariational reasoning does not improve substantially as a result of introductory physics instruction. To address these issues, we have begun work to identify subskills that underlie productive covariational reasoning in physics contexts. We present our preliminary work on the identification of "essential skills" related to covariational reasoning, and the development of a set of targeted online tasks to improve those skills.
