1. A sense of belonging: The role of higher education in retaining quality STEM teachers

   There is an alarming shortage of qualified STEM teachers in American PK-12 schools. The COVID-19 pandemic may exacerbate this crisis and consequently affect who participates in future STEM innovation. At three points during the pandemic, we surveyed early career teachers who were supported by the National Science Foundation as they began teaching in high-needs school districts. Teachers who felt connected to their professional and academic communities reported intentions to remain in the profession, while those who felt isolated reported intentions of leaving. It is critical for STEM academics to maintain professional relationships with graduates who pursue STEM teaching professions after graduation.

2. Peer-led team learning for introductory biology: relationships between peer-leader relatability, perceived role model status, and the potential influences of these variables on student learning gains

   https://doi.org/10.1186/s43031-020-00020-9  

   Winterton, Christina I.; Dunk, Ryan D.; Wiles, J. R. (February 2020, Disciplinary and Interdisciplinary Science Education Research)

   Student-instructor interactions have an influence on student achievement and perceptions of learning. In college and university settings, large introductory STEM courses are increasingly including Peer-Led Team Learning (PLTL), an evidence-based technique associated with improved student achievement, recruitment, and retention in STEM fields, especially for underserved populations. Within this technique, peer leaders hold a unique position in a student’s education. Peer leaders have relevant experience in that they have had recent success in the courses in which they facilitate student learning, yet, compared to student-faculty or student-teaching assistant relationships, there is minimal imbalance of authority or power. Students might find their peer leaders to be more relatable than faculty or graduate teaching assistants, and may even consider them to be role models. We explored students’ perceptions of peer leader relatability and role model status in relation to students’ achievement and their perceived learning gains in the context of an introductory biology course with an associated PLTL program. The final course grades and self-assessed learning gains of PLTL students who felt they related to their peer leader were compared to those who did not. We also compared final course grades and self-assessed learning gains between PLTL students who viewed their peer leader as a role model versus those who did not. Self-reported learning gains were significantly higher for students who relate to their peer leader, as well as for students who viewed their peer leaders as a role model. There is some support that this trend is stronger for STEM majors versus those who are not enrolled in a STEM program, though the interaction is not significant. Significant differences in overall course grade were only observed between students who reported that they related to their peer leader versus those who did not relate to their peer leader.

3. Recognition of Tactile Facial Action Units by Individuals Who Are Blind and Sighted: A Comparative Study

   https://doi.org/10.3390/mti3020032  

   McDaniel, Troy; Tran, Diep; Chowdhury, Abhik; Fakhri, Bijan; Panchanathan, Sethuraman (June 2019, Multimodal Technologies and Interaction)

   Given that most cues exchanged during a social interaction are nonverbal (e.g., facial expressions, hand gestures, body language), individuals who are blind are at a social disadvantage compared to their sighted peers. Very little work has explored sensory augmentation in the context of social assistive aids for individuals who are blind. The purpose of this study is to explore the following questions related to visual-to-vibrotactile mapping of facial action units (the building blocks of facial expressions): (1) How well can individuals who are blind recognize tactile facial action units compared to those who are sighted? (2) How well can individuals who are blind recognize emotions from tactile facial action units compared to those who are sighted? These questions are explored in a preliminary pilot test using absolute identification tasks in which participants learn and recognize vibrotactile stimulations presented through the Haptic Chair, a custom vibrotactile display embedded on the back of a chair. Study results show that individuals who are blind are able to recognize tactile facial action units as well as those who are sighted. These results hint at the potential for tactile facial action units to augment and expand access to social interactions for individuals who are blind.

4. User-centered personas for PhysPort

   https://doi.org/10.1119/perc.2019.pr.Madsen

   PhysPort is a professional development website for physics faculty to develop their teaching through research-based resources. As part of PhysPort's ongoing research efforts, we conducted interviews with 23 physics faculty from diverse instructional and institutional contexts in the US. From our interviews, we sought common experiences, motivations, and pain points to develop personas--person-like constructs--of physics faculty in the US. Our research focuses on the perspectives of the key users of our site, and thus we take a user-centered perspective rather than a researcher-centered perspective. We developed personas, which are person-like constructs that are developed based on salient characteristics of actual users, that enable designers to create resources to meet actual user needs without designing for the idiosyncrasies of specific users. We present our set of six personas of physics faculty members: a faculty member who is new to improving his teaching; one who takes up his department's practices; one who wants her teaching to feel good; one who is comfortable in her teaching; one who is continuously improving; and one who solves big problems in her department. These personas of physics faculty making changes to their teaching can be used more broadly to improve the design and development of professional development resources and activities for physics faculty.

5. Opposing dimensions in mathematicians' counter narratives written for undergraduate students

   Melhuish, Kate; Guajardo, Lino; Contreras, Norman; Dawkins, Paul C; Diaz-Lopez, Alexander; Garcia, Rebecca; Lew, Kristen; Harris, Pamela; Roh, Kyeong_Hah; Walker, Shanise; et al (November 2024, Special Interest Group of the Mathematics Association of America on Research in Undergraduate Mathematics Education)

   In mathematics, counter narratives can be used to fight the dominant narrative of who is good at mathematics and who can succeed in mathematics. Eight mathematicians were recruited to co-author a larger NSF project (RAMP). In part, they were asked to create author stories for an undergraduate audience. In this article, we use narrative analysis to present five polarities identified in the author stories. We present various quotations from the mathematicians’ author stories to highlight their experiences with home and school life, view of what mathematics is, experiences in growth in mathematics, with collaboration, and their feelings of community in mathematics. The telling of these experiences contributes towards rehumanizing mathematics and rewriting the narrative of who is good at and who can succeed in mathematics.
