During the anthropogenic disaster of the coronavirus pandemic (COVID19), all courses at universities across the country switched to online modalities mid-semester. At the University of Nebraska Omaha, we have used the Communities of Inquiry (COI) framework as the basis for recreating the interplay between instructor, content, and student presence present in the reformed versions of our face-to-face introductory physics courses. In this presentation, we discuss the COI, the various types of important interactions necessary for high-impact instruction, and specifics on recreating these interactions online for a physics course including a laboratory component. We also present preliminary results showing no significant decrease in student learning resulting from the mid-semester change of format.

The 2020 AAPT Virtual Summer Meeting brought together physics educators from around the globe to learn about the latest in physics theory, research methodology and education from leaders in their field. 

Interpreting and understanding the way students use and understand the mathematics used in physics is a central theme in Physics Education Research. Physical phenomena described by partial differential equations (PDEs) provide a promising context to study how students combine physics and mathematics. An example is the description of heat flow and temperature distribution in a one-dimensional rod, which can be described by the (1D) heat equation, together with an initial condition (IC), and boundary conditions (BCs). In this contribution, we present data from an interview study where we gave students the mathematical description of a system (PDE, IC and BCs) together with the analytical solution. We asked to describe the time evolution of the system, both in mathematical and physical terms. Our analysis shows that students’ reasoning is mainly mathematical with little reference to the underlying physics and that most students do not connect their mathematical statements to physical processes.

Technical-Vocational Education (TVE) Students’ Mental Models about Electric Circuits

Undergraduate physics students are often required to take a course in computational methods. I will describe an approach to presenting this course in a flipped format. The background lecture for each topic are moved outside of the classroom, in the form of YouTube videos embedded in interactive Jupyter notebooks. A Jupyter notebook is an open-source web application that combines formatted text, executable code, images, videos, and interactive widgets. A plugin for the notebook, called nbgrader, provides for automated grading of coded assignments. In class, students work in small groups to complete programming challenges, applying the techniques described in the videos. The first two assignments each week included built in automated tests, while the more challenging third assignment does not. This approach provides students with immediate feedback as they develop their coding skills, while also encouraging them to think of ways to debug their own code. Students also complete two larger group projects in place of a midterm and final exam. Surveys of student attitudes showed a preference for the flipped presentation when compared to a traditional section of the course, while learning outcomes were equivalent.

Teaching Computational Methods in a Flipped Format

The essence of laboratory experiences is the gathering of data, analyzing data, forming hypotheses, comparing with models and theories, discussion sources of and estimating statistical and systematic uncertainties, and drawing conclusions, usually in the form of a lab report. All of these components have been replicated in a complete set of first- and second-semester laboratory online experiments at Michigan State University, which can be used to enable undergraduate students to obtain authentic laboratory experiences while staying off campus. The availability of these online labs is crucial, even in universities planning to resume on-campus teaching in the fall, because groups of students in high risk groups need accommodations to remain sheltered during the pandemic. All of these experiments do not need special software, can be run on a web-browser on any computer, tablet device, or even smartphone, and in this way do not contribute to widening the digital divide.

Hands-on Lab Experiences With Social Distancing

Numerical modeling is used extensively in astrophysics and -- when used in a classroom -- allows students to explore how models are built in physics in general and how model building is facilitated by computational methods in particular. It also exposes them to ubiquitous tools such as Python and Runge-Kutta. Using a relatively simple N-body simulation students are able to go beyond the usual Kepler's Third law introductory descriptions of orbital dynamics and examine 3-body and chaos effects. I will show some cases where students encounter questions which are central to the current state-of-the-art in planetary dynamics research.

We have implemented a framework for personalized remote learning in an introductory algebra-based physics course at the University of Alabama at Birmingham. This framework, developed to address issues related to equity and inclusion, is based on a combination of strategies from physics education research and best practices in online learning. Our approach centers around the Gameful Learning pedagogy. Within this framework, we have incorporated several interventions including (1) the adaptive learning platform ALEKS for mathematical remediation (2) activities in metacognition and (3) a physics teaching-assistant managed “virtual help desk”. The implementation of this framework, materials developed, and experiences delivering the curriculum to a diverse student population during COVID-19 will be discussed.

Applying “Gameful Learning” in a Remote Introductory Physics Course

The Newton´s laboratory is an app created under Unity development platform (C and C ++ language) implemented to COLAF (Colombian Air Force) Cadets, whom allow them to go further in the researching field, improve their skills on the basic fundamentals of physics (Newton´s Laws) for applications in aerospace projects. Military personnel are undergraduate students who are subjected to a rhythm of life of constant physical demand, discipline, stress and mental development that are simultaneously complemented by academic training. The impact of the interaction of the cadets with this implemented tool, the contribution to their professional development and the future influence on the use of new technological applications in the training of the Colombian aerospace leaders are evaluated and the results are presented. This app was implemented as a way of supporting the education system due to the ongoin global pandemic.

We present our pedagogical experiences and practitioner recommendations for introductory physics undergraduate laboratories using the Scale-Up methodology, in the context of the sudden adaptation to the online teaching environment due to the COVID-19 pandemic. Specifically, we focus on the challenges of implementing focused critical-thinking labs with a diverse student population and graduate teaching staff ill-prepared for such a quick and forced transition. Given the task of achieving pre-COVID-19 learning objectives without providing physical access to laboratory materials, we examine the demonstrated benefits and disadvantages of several tools, such as technology, university resources, communication methods, and leadership skills.

Remote Delivery of Introductory Physics Labs During the COVID-19 Transition Period

Canadian Universities suspended regular in-person classes around mid-March due to the growing concerns about the pandemics. At my Department, the switch to the emergency remote teaching proceeded relatively smoothly, with remote classes up and running within one week. The synchronous lectures and office hours were conducted via zoom. It helped that the asynchronous online homework already existed as a part of a regular course. Not surprisingly, the real challenge turned out to be a remote testing part. The talk will discuss the challenges of running a traditional exam remotely, and the pressing need for the meaningful alternative ways of evaluating the students while teaching remotely.

Lessons From Remote Testing

The physics education and computer science researchers at Ithaca College collaborated to develop a mobile application to provide students with a dynamic experience studying electric fields, a notoriously difficult topic. This study is the first in a longitudinal study comparing the impacts of the mobile application and paired worksheet activity to other learning tools including a laptop simulation and a worksheet-only activity. Participants include health science majors enrolled in an algebra-based physics class. The normalized gain in performance on a diagnostic administered prior to and after interacting with one of the three activities was used to measure the impact of each activity on student understanding. Student attitude was measured using a questionnaire in the post-activity diagnostic. The results show students prefer laptop activities as physics learning aids and students in the two sections, mobile application and laptop simulation, produced higher average gains in learning than those in the worksheet-only section.

Developing and Testing a New Educational App about Electric Fields

We present our experience of conducting first semester calculus-based introductory physics laboratories remotely in the Spring 2020 semester. Six laboratories were redesigned to give students maximally hands-on experience under the restrains of coronavirus stay-at-home conditions. The video analysis by using Tracker software was used to collect and process the experimental data for most of these labs. The lessons learned allowed us to confidently teach the full semester of the labs remotely the following Summer 2020 semester.
