Faculty and graduate students develop as education researchers through different avenues. One possible path is through their participation in the Professional development for Emerging Education Researchers (PEER) program, which is designed to develop participants&#39; discipline-based education research through hands-on activities during a series of workshops. We collected data before and during participation in one of the editions of this program conducted entirely online with primarily physics and math faculty. This data allows us to examine in what ways engagement in the workshops affects participants&#39; research ideas and their self-efficacy. In particular, we explore the ways in which participants&#39; perception of their growth in the field evolves as they engage in this professional development program. This work will enable us to analyze the impact of this virtual professional development experience as well as gain a deeper understanding of different facets of emerging education researchers’ professional development.

**Making Physics More Inclusive and Eliminating Exclusionary Practices in Physics**

As a gateway discipline to STEM majors and careers, physics plays a central role in deciding who does, and who doesn't, get to discover and pursue scientific careers. Technical and scientific professionals are rewarded with economic privilege and status which affords them both social and cultural power. Therefore, social justice will be realized only when the opportunity, and the choice, to excel in physics is open to all students. The culture and practices of the physics classroom reflect the culture of physics at large, which raises the question of how our professional physics communities can embrace, rather than inadvertently repel, a diverse group of academics that can help improve physics culture.  To this end, the 2021 Physics Education Research Conference will focus on defining inclusive spaces and practices. Additionally, we will explore strategies for eliminating exclusionary practices in our classrooms, research spaces, and professional organizations. We call on the community to propose sessions that will drive conversations related to these initiatives throughout PERC 2021.

We report on the development of a written assessment designed to analyze pedagogical content knowledge in the context of questioning (PCK-Q). We discuss the process of analyzing and coding classroom videos and writing and testing a written assessment. The classroom observations have first been coded using a coding scheme that analyzes levels of questioning in an inquiry-based classroom. A written instrument was then developed based on the classroom videos, administered to student teaching assistants (TAs and LAs) and compared with the video results to validate the written instrument. We report on the coding scheme and the validation of results as part of this ongoing project.

This study advances the work of previous studies that have applied machine learning algorithms to identify students who are at risk of failure in introductory calculus-based physics. Those prior studies found it very difficult to predict the outcome of students who received a D, and F, or W (withdrawal from the course). This study applies ensemble machine learning—using two or more machine learning algorithms in tandem—to identify students at-risk of failing introductory calculus-based physics. These algorithms are applied using institutional variables such as college GPA and in-class variables such as homework grades. Non-cognitive variables gathered through in-class surveys, such as self-efficacy, are also used to improve identification accuracy.

Using Ensemble Machine Learning to Identify At-Risk Physics Students

MILES (Mentoring Innovative Learning Experiences for Students) at Santa Rosa Junior College (SRJC) is a National Science Foundation (NSF) S-STEM funded program designed to improve the academic outcomes of high-achieving, low-income STEM students. The program provides students not only with financial aid, but also a cohort experience with like-minded peers, an SRJC faculty mentor, and workshops and a one-unit class to build career skills. As originally conceived, students would enroll in cohorts of 20 for up to three years before transferring to a four-year degree granting institution. Now in the third year of the five-year grant, we will discuss the outcomes and challenges of this program so far. This work was supported by NSF DUE-1742635 and by Santa Rosa Junior College.

STEM MILES: Mentoring Innovative Learning Experiences for Students

This poster analyzes two examples of whiteboard meetings from a college calculus-based introductory physics course taught using University Modeling Instruction. In this pedagogy, students work in small groups to create a solution to the same problem on 2′ × 3′ whiteboards. They then sit in a large circle with their whiteboards held facing in and conduct a student-led whole-class discussion (“board” meeting) to reach a consensus. One example is given of a conversation where students overcame sharp disagreements to eventually reach whole-class consensus and another example is given where they did not. We examine how social positioning contributed to students either successfully examining and resolving different ideas or failing to do so. Our analysis suggests that the way students position themselves in discussions may open or close the collaborative space to productive sense-making.

Social-positioning correlates with consensus building in two contentious large-group meetings

In his well-known paper Hake states that “a consistent analysis over diverse student populations with widely varying initial knowledge states […] can be obtained by taking the normalized average gain <g> as a rough measure of the effectiveness of the course in promoting conceptual understanding.” The practice of measuring course learning gains is common, despite the fact that variation in <g> on the FCI has also been tied to population effects, such as SAT scores, along which diverse populations are spread [Coletta, 2007]. In our data set of thousands of introductory mechanics students over more than a decade, we see a strong correlation between FMCE gain and math preparation level. We present the lessons we have learned about using normalized gain to study physics instruction, and we suggest how PER researchers might move beyond it to better compare learning in courses that reflect the diversity of the student population.

Looking Beyond the Normalized Gain

Computer simulations have been used to support student learning in physics, not only to boost conceptual understanding but to make labs more widely accessible to different populations. However, their impact on student learning has shown mixed results. To better understand this impact, HTML5-based computer simulations for topics in mechanics were investigated in a large, algebra-based, studio physics course for life science students at a private, research-intensive institution. Over a period of three years, we compared learning outcomes of students using traditional hands-on equipment only, a simulation only, or a hybrid combination of both for activities on energy, momentum, simple harmonic motion, and rotational dynamics. We will present our findings of this study through an equity lens, both from the experience of online learning due to the global pandemic and from consideration of the limited access to lab equipment for many students.

Use of physics simulations in supporting equity and student learning

Calls to reform to science teaching have elicited numerous responses over the past decade. One avenue of reform, 3 Dimensional Learning (3DL), focuses on what students learn, instead of how students learn. 3DL achieves this by organizing science learning around the same 3 dimensions that experts organize their knowledge: Scientific Practices, Disciplinary Core Ideas, and Crosscutting Concepts. To aid transformations toward 3DL, the 3DL4US group has created protocols to help characterize when 3DL may occur on assessments and in instruction. In this talk, we present initial results that extend this effort to student engagement with the Scientific Practice of Developing and Using Models. We will look at results from student problem solving interviews to see how the practice manifested in their work. These results will help inform us about the effectiveness of instructional efforts to engage students with the Practice of Using Models as we attempt to create 3DL environments.

Student Engagement in the Practice of Developing and Using Models

Many students who enter college wanting to major in STEM, particularly females and members from underrepresented groups, end up switching to non-STEM majors. At the U.S. Air Force Academy, specifically, previous studies have uncovered that, despite a strong academic preparation, of the cadets who reported their intention to complete a STEM degree as incoming freshmen, 36.4% graduated in a non-STEM discipline, with quantitative classes (Calculus-based Physics, Calculus I, Chemistry I) pinpointed by the data analysis as gateways. In this follow-up study (Year 3), data from the Registrar’s Office and a cadet survey were analyzed to identify factors associated with STEM attrition, a starting point for the conceptualization of strategies to address it at the U.S. Air Force Academy and in Puerto Rican universities.

Advisors and graduate students are sometimes stuck and not moving their research forward. We use Deliberate Innovation(DI) techniques to understand the specific situations centered around research that graduate students and their advisors find themselves in that may be problematic. A critical element of this is determining whether advisors and advisees show indifference in particular situations. We understand indifference by noticing what people are and are not drawn to in the research setting, and will be focusing on ways in which we have seen it show up. Finding this indifference allows us to know where to focus our attention, with the ultimate goal of finding situations in which we can help graduate students and advisors get unstuck and move their research forward.

Using Deliberate Innovation to Understand Indifference in Graduate Advisor/Advisee Relationships

Motion is used in a variety of ways in introductory mechanics contexts. Given the foundational importance of related ideas such as force and acceleration, it might behoove instructors to understand how their students are interpreting this all-encompassing word. In this study, we explored how beliefs and conceptions about motion are refined or used by undergraduate, upper-division physics students in a series of think-aloud interviews with coupled-multiple response (CMR) items developed from free-response data and with two adapted example questions from the Force and Motion Conceptual Evaluation (FMCE).
