Through reflective journaling, the Alma project at San Francisco State University (an HSI) seeks to affirm STEM students’ identities, support connections with their life experiences, and recognize their cultural wealth. Our department offers a number of introductory physics and astronomy lecture and lab sequences including: a three-semester calculus-based physics sequence targeted toward engineering, computer science and physical science majors; a two-semester algebra-based physics sequence targeted toward students in the biosciences; a one-semester conceptual physics course; and one-semester conceptual astronomy course. In response to the prompt “why am I here,” designed to draw out their values and purpose, students journaled for 5 - 10 minutes and then spent time in class sharing their responses. Using an iterative thematic coding approach, we analyzed more than 400 essays and identified 11 cultural capitals expressed by students. Here we compare and contrast the frequencies of cultural capitals exhibited by respondents in different course types.

Individual instructors’ perspectives of disability impact the experiences of disabled students. For example, if a person considers disability as mainly an individual deficit (i.e., aligned with individual or medical models), they will likely place the onus on the disabled student to fit into the existing education system. On the other hand, if a person considers disability as arising from the interaction of socially constructed spaces and practices (i.e., aligned with a social model), they may more likely consider systemic reform. As part of developing an observation protocol for inclusive teaching practices in postsecondary STEM, we interviewed experts from several relevant disciplines, including postsecondary physics and chemistry instructors, STEM discipline-based education researchers, and researchers in exceptional/special education. We will present convergences and divergences in the trends of how these experts discussed disability and inclusive teaching in postsecondary STEM and consider the implications of these perspectives for disabled students.


Experts’ Perspectives on Disability in Postsecondary STEM Across Disciplines

Over the last 4 years, our team has been designing and running online faculty learning communities (FOLCs) to support faculty in adopting the Next Generation Physical Sciences and Everyday Thinking (NGPET) curriculum to their contexts. Due to the highly interactive nature of the NGPET curriculum, faculty often discuss issues with student collaboration and pacing. In these conversations, faculty, at times, bring disenfranchising narratives about students to the table when making sense of these problems of practice. We investigate when disenfranchising narratives are disrupted in these conversations in an effort to understand how this disruption occurs. Additionally, we will investigate when these discursive challenges succeed in converging on more liberatory narratives about students. In this talk, we will showcase examples of disenfranchising narratives about students, how these narratives are disrupted discursively, and how the conversations converged. 


Modeling Disrupting Disenfranchising Narratives about Students in Faculty Conversations

In 2019 we conducted a nationwide survey (n=3,769) of teaching practices in introductory undergraduate math, physics, and chemistry courses. Survey results identified departments in the top quarter of their discipline in terms of class time spent on non-lecture activities in their introductory courses. We interviewed 29 instructors from 18 of these departments (including 11 physics instructors representing 6 departments), sampling from a range of institution types, in order to identify factors contributing to their success. We found that departments with high use of active learning in intro courses have local champions of teaching reform who are very knowledgeable about pedagogy and are supported concretely by institution and departmental resources and culture. In this talk, we focus on the variety of institution and department level characteristics that were present in departments with high use of active learning in their intro courses and how they differentially supported teaching reform.

Department and institution factors supporting active learning in intro courses

Research has shown that elementary school teachers report an intention to integrate engineering education into their classrooms (Uğraş & Genç, 2018; Kang, Donovan & McCarthy, 2018); however, they also report low confidence in their ability to teach engineering (Trygstad, 2013). In response, we developed curricular modules that include both physics and engineering instruction through a Research Practice Partnership with a local interactive science center. Each module includes four activities that include an investigation about a physics phenomenon and introduces the engineering design process across the classroom and museum learning spaces. In this paper, we analyze post-module interviews with K-6 grade teachers to understand their view of engineering activities. Using the Didactic Triangle to guide our work, we present a snapshot of teacher perceptions and suggestions for supporting teachers when engaging students in physics-based engineering design activities. These findings are also useful for other physics outreach programs that work with elementary teachers. 


Teacher views of physics-based engineering activities

Change efforts in higher education are increasingly focused at the department-level, allowing for the benefits of a grassroots approach while also incorporating top-down implementation. Two models for departmentally-based change are the Departmental Action Team (DAT) Project and Teaching Quality Framework (TQF) Initiative. In both models, externally-facilitated working groups meet regularly to work on projects relevant to their departments, though the focus and scope of teams’ work differs. To better understand how these models of institutional change operate and their implications for change work in higher education, we interviewed individuals from both efforts, including facilitators and grant PIs. Our results indicate that differences between the models have connections to the theories underlying each, and they have implications for participants’ experiences and working groups’ outcomes. We present these differences in the working group process in the two change models, the potential impact of these differences, and implications for others doing change work.

Fostering departmental change through collaboration: an analysis of two approaches

Facilitating discussions on pedagogy and content among high school teachers with different backgrounds can be a challenging undertaking. By becoming attuned to the mechanisms by which discourse moves in expert-novice teacher pairs successfully elevate conversations about content and pedagogy, facilitators of physics teacher professional development (PD) can better design activities and support teacher groups in advancing toward a conversational mode in which all parties feel comfortable contributing. Last summer, the Illinois Physics and Secondary Schools (IPaSS) partnership offered intensive PD workshops for high school teachers. This talk presents a case-study of an expert-novice pair solving problems from a Content Knowledge for Teaching Energy (CKT-E) assessment. Via video analysis, we examine the question: What conversational moves facilitate conversations about physics content and pedagogy between teachers with different backgrounds? In the case study, moves by both teachers minimize apparent disparities in power, creating conversational space and setting the stage for content-specific discussion.

Enabling content-specific discussions among expert-novice teacher pairs: A case study

I have been serving as an AAAS-Science and Technology Policy Fellow at the National Science Foundation in the Division of Undergraduate Education for the last two years. I will share lessons learned from this experience about communicating with government officials. Specifically, I will focus on reframing STEM education and education research as multifaceted tools for science advocacy. I will also discuss program and project evaluation as underutilized tools for the promotion of STEM. Improving the way educators and educational researchers collect and share project and program results can facilitate communication among researchers, educators, nonprofits, and government and assist these entities in promoting STEM and STEM education.

STEM Education and Education Research as Tools for Science Advocacy/Communication

The National Academies of Sciences, Engineering, and Medicine (NASEM) provide independent, science-based, non-partisan policy advice to federal agencies and Congress. The Committee on Planetary Protection (CoPP), a discipline committee of the Space Studies Board, provides advice to NASA on the critical issue of planetary protection. Planetary protection includes measures devised for robotic spacecraft and human exploration missions to protect the biological and environmental integrity of extraterrestrial bodies for future scientific studies as well as life on Earth against potential “backward” contamination. Through discussions with scientists across the world, the CoPP endeavors to ensure that space missions can answer fundamental questions about life and the history of our Solar System without jeopardizing future science through harmful contamination of pristine extraterrestrial sites. I will discuss how CoPP and similar committees demonstrate science advocacy and communication with government officials, and how CoPP uses science to promote and protect future studies and exploration.

NASEM's Committee on Planetary Protection: Advocating With and For Science

As with any form of communication, advocacy for science and science policy requires identifying key audiences and opportunities. In this presentation, some of the main opportunities for advocacy with the Executive and Legislative Branches are identified and illustrated. As a preface and because of the tight coupling with advocacy opportunities, the Federal budgetary cycle is briefly reviewed. The speaker participated in science advocacy and policy development from multiple perspective as a member of the Office of Science and Technology Policy and with responsibility for university federal relations at Northern Illinois University.
