Blended learning with flipped classrooms – where online pre-class instruction precedes highly interactive classes - outperforms traditional pedagogy. It also challenges the organizational and cognitive load capabilities of instructors. Placing the required resources: videos, interleaved questions, in-class activities (short instructor presentations, group problems, and other activities), homework, and quizzes in a single online platform allows creating and organizing assignments to fit various weekly class schedules. I will describe an Introductory calculus-based Mechanics course using the Modeling Approach to Problem Solving pedagogy (1&amp;2), emphasizing the online in-class activities. We use the edX platform to handle and deploy the resources, supplemented by an organizational software package that displays sufficient metadata to create and assess a balanced learning experience, and to improve outcomes year to year based on the collected metadata. We are grateful to MIT for help generating resources and making the organizational software package. Please consider adapting this course for your students.

technical paper

We take a social network analysis approach to investigate how members of an online teacher community interact with each other through a nine-week classical mechanics summer course. The class, associated with the Master program in physics with teaching emphasis at Texas A&M University-Commerce, requires students to participate in weekly problem solving and biweekly reading reflection discussion boards. We measured the weekly activity level for the community and number of interactions between students, and compared these to the average values determined for the entire semester. We found that the participation of students in problem solving discussions fluctuates from week to week; revealing the activity of the community of practice, influence of student backgrounds, and possible structural features of the course. Comparatively, the reading reflection participation did not show a noticeable variation. In order to gain more insight into our findings we characterized the types of interactions by categorizing student communication.

Applying Social Network Analysis to an Online Community of Practice for Teachers

We investigated how participation in a semester-long after-school teaching experience attracts undergraduate STEM majors to consider a career in teaching. The students were asked several questions about their attitudes towards teaching in high-need districts before and after the experience through surveys and interviews. Preliminary analysis suggests that experience with teaching in this program does lead STEM majors to consider teaching as a career. However, our sample was not ideal, since students typically need to declare their second major in secondary education in their sophomore year in order to fit all of the course requirements in four years. The strong interest in teaching as a career among graduating seniors was striking and leads us to conclude that earlier intervention with a teaching experience could spark interest in teaching in time to add the secondary education major, thus ensuring that the students are well prepared upon entering the classroom.

Attracting STEM-Talented Undergraduates to Secondary Education with Early Teaching Experiences

The slowly charging capacitor is the standard example used to illustrate that the displacement current is needed in Ampere’s Law if we want to correctly determine the magnetic field between the capacitor plates. However, it is not widely recognized that in any quasi-static situation the magnetic field can also be determined using the Biot-Savart Law with just real currents. In this presentation, we will see how including the effects of the surface currents on the plates helps explain the resulting magnetic field both between the plates and outside the plates. It is very likely that the results will surprise most viewers. Discussing these issues in an upper division physics course would provide students with additional physical insight into this interesting system.

Untold secrets of the slowly charging capacitor

Using matched PhysPort data, we assess the utility of plotting gains as a function of pre-test scores on the Force Concept Inventory (FCI). Doing so has the advantage of providing nuance regarding differences in populations, whether it be to shed light on the efficacy of instructional methods or equity among different student populations. We empirically compare raw and normalized gains and find for a population of 9,354 students that neither the raw nor the normalized gain is uniform for students of all pre-FCI scores. We suggest alternative methods for quantifying gain, the relative gain, and the relative raw gain, on standardized assessments that overcome this diculty. We compare the relative gain measures to effect size and nd that each contributes to our understanding of gains. The relative gain measures are straightforward to interpret and visualize. We suggest effect size and other gain measures, particularly the relative gain measures, be used in a complementary way to better assess the differences between populations.

Gains as a function of pre-test scores

Physics students enter into a broad range of careers. It can be challenging to know not just what kinds of positions physics majors can apply for but how physics students can find jobs that they are well suited for. This lighthearted talk will briefly provide data round undergraduate student employment but focus on how students can find and how advisers can help undergraduates apply for positions.

Careers for Undergraduate Physics Majors

Following the example in "Developing scientific decision making by structuring and supporting student agency" by N.G. Holmes, et al, students designed the research question in a three-week sequence and a written lab report was replaced with an online synchronous oral lab report, followed by time for questions from student colleagues. I will report on enhanced student engagement in class and in office hours and will share anecdotal comments. Students participated in a "belonging intervention". I will share practical lessons learned.

Giving students agency increased engagement at just the right time

Next Generation Physical Science and Everyday Thinking (Next Gen PET) – a research-based, guided-inquiry, physical science curriculum has been implemented at the University of Northern Iowa (UNI) in a required science course for elementary education majors since Fall 2016. We teach the studio version of Next Gen PET in 4 sections of the course each Fall and Spring Semester. Since Summer 2016, we have offered an on-line version of the course for 6 weeks to help meet demand for the course. In Spring 2020, the course transitioned from on-campus, in-person instruction to on-line instruction in March due to the outbreak of COVID-19. This presentation will share how we have transitioned to on-line instruction with Next Gen PET and include insights we have gained with comparisons made of going on-line by choice versus being forced due to COVID-19.

Hands-on Minds-on Engagement through Remote Learning

Active learning has been shown to be more effective than passive lecture methods, but more work must be done to understand what mechanisms lead to effective active learning environments. The first step in understanding the mechanisms of active learning pedagogies is to establish a vocabulary with which to characterize them. One such method we have used is the Classroom Observation Protocol for Undergraduate STEM (COPUS), which codes student and instructor activities in two minute intervals. These profiles give us a picture of what kinds of activities are occurring in the classroom with the implementation of a given pedagogy. We have gathered COPUS profiles for six active learning pedagogies in physics. We discuss the individual characteristics for each pedagogy and present results from latent profile analyses.

Characterizing Active Learning Environments in Physics using COPUS

One argument for keeping the physics GRE is that it can help applicants who might otherwise be missed in the admissions process stand out. In this work, we evaluate whether this claim is supported by physics graduate school admissions decisions. We used admissions data from five PhD-granting physics departments over a 2-year period to see how the fraction of applicants admitted varied based on their physics GRE scores. We compared applicants with low GPAs to applicants with higher GPAs and applicants from large undergraduate universities to applicants from smaller undergraduate universities. We find that for applicants who might otherwise have been missed (e.g. have a low GPA or attended a small school) having a high physics GRE score did not seem to increase the applicant’s chances of being admitted to the schools. However, having a low physics GRE score seemed to penalize otherwise competitive applicants.
