The term &#39;Representations&#39; refers to sketches, diagrams, pictures, graphs, tables, and mathematical equations are representations we commonly use in undergraduate physics courses and STEM more broadly. Even though expert instructors are familiar with these representations, the studies show that novice students are often struggling to understand and use these representations. Studies on the use of social semiotics in physics classrooms suggest that the instructors explain representations at a basic level and then, more in-depth, all physics representations. We collect student-generated problem-solving videos (Pencasts) from calculus- based physics courses at UGA. In this study, we analyze we look for patterns of students internalizing and combining representations to solve physics problems. In this poster, we present our initial findings. We find that students commonly use tables and visual representations with individualization to maximize learned skills and incorporate their understanding in the class. We expect to extend our work to other STEM branches.

The Tennessee Technological University - STEM Majors for Rural Teaching (TTU - SMaRT) Noyce program has partnered closely with TTU's Millard Oakley STEM Center. IN this poster we describe how this mututally beneficial partnership has provided a low-stakes environment in which Noyce students gain authentic instrucitonal experiences, exposure to pedagogical innovations, menaingful interaction with practicing teachers, and early integrations with the local STEM teaching community. This partnership has also enabled the STEM Center to offer more outreach opportunities than it otherwise could. Lessons developed by scholars have contributed to a 'library' of standards-based activities that have also broadened the scope of what can be offered.

This poster will address development and initial implementation of a NSF grant funded biomedically relevant active-learning curriculum in my second semester Physics for the Life Sciences course. This NSF grant funded curriculum provides students with a biomedically relevant curriculum that stresses the importance of physics as a basic science relevant to their future medical/healthcare careers. I will provide insight as to how I contributed in the development process and adapted curricular materials of Rotational Kinematics and Torque in a flipped classroom setting and how this benefited me in my pedagogical growth in teaching physics. Further, pre-post analysis of attitude survey results will be addressed to show the effectiveness of the curriculum. This work is supported by the grants DUE- 1934038 and DUE- 1933984 from the National Science Foundation.

Our open-source textbook, Exploring Physical Phenomena: What Happens When Light from the Sun Shines on the Earth? is now available at https://open.oregonstate.education/physicsforteachers. Each unit begins by identifying student resources for learning, developing central ideas based on evidence from exploring phenomena with everyday equipment and materials, using central ideas to explain intriguing phenomena, developing mathematical representations of the phenomena, using those representations to predict or estimate a quantity of interest, and making connections to educational policies such as the Next Generation Science Standards. All units include examples of student work by prospective elementary and middle school teachers while exploring light and thermal phenomena, considering the influence of light and thermal phenomena on local weather and global climate change, and exploring astronomical phenomena in the context of the Sun/Earth/Moon system. Supplemental materials include instructor guide for each unit, equipment lists for both on-campus and remote instruction, student handouts, and example homework assignments.

We report the design and development process undertaken by the authors in putting together historical vignettes that could be used as supplementary materials in teaching Physical Science in Senior High School. The use of historical physics vignettes humanizes science to the students and allows them to develop an understanding of the nature of science. In this paper, we present three examples of the historical vignettes that had been developed: (1) an interactive historical vignette about Galileo and his ast ronomical discoveries; (2) a vignette presented in role-play format that highlights the cont ributions of Oersted, Ampere, Faraday, and Maxwell; and (3) a comics-format vignette contextualized in the Philippines setting, featuring the story of the first female National Scientist of the Philippines. The vignettes featured guide questions that encourage the students to think about their views about the nature of science.

This AGEP Alliance model provides faculty professional development and career preparation to minority STEM doctoral candidates. To increase the numbers of historically underrepresented faculty in STEM, the target audience is instructors at Historically Black Colleges and Universities (HBCUs) that are in the dissertation stage of their PhD degree.  The Alliance’s HBCU Instructors Bridge to Academia Program (HI Bridge) consists of research seminars, research advising, faculty mentoring, research presentations, peer collaboration, networking, and alumni follow-up meetings.  These activities are designed to support the candidates in completing their PhDs and prepare them for success in their faculty careers. Our work is also designed to identify factors that influence attrition rates of the target audience. We will be presenting the organizational structure of the Alliance team and the progress that has been made with the first cohort of participants.

We implemented a fully online full year introductory physics sequence for life science and pre-health students at Portland State University during the 2020- 2021 school year. Curricular materials such as videos by experts in the medical field, content, activities, simulations, and assessments around medical examples and applications were developed. These were delivered through an adaptive, personalized, and interactive online platform Cogbooks. We plan to offer this course in-class in the upcoming school year and further study student learning and the impact of the curriculum on student attitudes.

This work is part of a multi-institution collaboration developing a fair, valid, and reliable research-based conceptual fluids assessment, the Fluids Conceptual Evaluation (FCE). The FCE will utilize two-tier multiple-choice items covering both fluids statics and fluids dynamics. Rasch analysis will be used to create different equivalent versions of the FCE, allowing instructors to give just the statics questions, just the dynamics questions, or a combination of both. In this poster we will describe the process of how we selected the fluid dynamics constructs and the process of writing and refining the dynamics-related questions. Instructors interested in serving as a field test site should contact Project Lead Dawn Meredith.

How does one run a virtual physics camp for middle school girls during the COVID pandemic ? I will present my experience in organizing and executing the Virtual Physics Wonder Girls Summer Camp in 2021. The theme of this year's free, week-long physics camp revolves around renewable energies and quantum physics. On its ninth year, the camp provides immersion experiences to cohorts of middle school girls selected from a pool of high-performing students in the Philadelphia-New Jersey area. Campers come from diverse communities and are introduced to renewable energy and the basics of solar cells, and experience project-building by building and testing solar cars, and solar boats, and do hands-on optics experiments. Campers received a free kit of materials for projects and experiments. Campers interact with physics majors who serve as crew, women physicists and engineers, experience virtual tours of plants and manufacturing facilities, and give capstone presentations.

Anxiety is the top mental health concern among undergraduates and thought to be particularly high among science students. However, there is little known about how online science courses affect anxiety. In this study, we surveyed over 2100 undergraduates about their anxiety in large-enrollment online science courses. We used open-coding and logistic regression to analyze the data. Students reported that technology issues (69.8%), proctored exams (68.0%), and difficulty getting to know peers (67.2%) increased their anxiety online. Accessing content at a later time (79.0%), attending class from where students want (74.4%), and not having to be on camera (73.5%) decreased their anxiety. Students suggested that instructors could decrease anxiety in online courses by increasing test-taking flexibility (25.0%) and having an organized course (14.7%). This study provides insight into how instructors can create more inclusive online learning environments for students with anxiety.

The parallel plate capacitors are used in many applications. The calculation of voltage of the two triboelectric plates is very important to calculate the maximum potential difference that can be obtained in triboelectric nano generators. Due to fringing of electric field lines the potential difference between the two plates varies in a nonlinear manner with separation distance and plate size. The nature of the field variation and hence the average potential difference as a function of plate size is simulated and the separation for maximum potential difference is calculated. To have a better insight, the energy calculation is also performed. This enables us to calculate the voltage generated by nano generators and hence the maximum obtainable power.
