Engaging Mathematicians One Step At A Time: Math Trails, Mary L. Dalton, Jennifer Yantz
Journal of Humanistic Mathematics
Mathematics is present in everything we see and do. Sometimes we look past it, looking for some mathematical mystery when the beauty of mathematics is evident in the most obvious ways. One way to engage students to notice connections to mathematics in these everyday objects and events is to direct them in a guided math trail. A math trail is an activity where participants follow a map or guide to various locations while they are encouraged to take notice of connections to mathematical patterns and concepts in the objects around them. An important benefit is that going on a math …
An Unlikely Duo: Injecting Art Projects In The Lower-Division Mathematics Classroom, Douglas T. Pfeffer, Christina Durón
An Unlikely Duo: Injecting Art Projects In The Lower-Division Mathematics Classroom, Douglas T. Pfeffer, Christina Durón
Journal of Humanistic Mathematics
Too often society has sterilized mathematics to the point that many view it as drab and deplete of aesthetic intrigue---in higher education, this is particularly true of students in the lower-division classroom. In this paper, we propose the use of art projects as a novel way to alter this perspective. Art projects function as a hands-on, active way to invite students to both identify connections between math and various non-mathematical disciplines as well as view math as overall more intriguing, inviting, and interesting. This paper details our implementation and discusses anonymously solicited survey data that highlights our successes.

Implementation And Assessment Of A Course-Based Undergraduate Research Experience (Cure) In General Microbiology, Sheritta Fagbodun
Critical Proceedings of the STEM ED Conference (2024)
The STEM workforce is large and fast-growing. However, underrepresented minorities- URMs (African Americans, Hispanics, and Native Americans) remain poorly represented within the STEM workforce. This is partly due to the lack of retention of URMs in STEM majors. It has been shown by various studies that immersion in undergraduate research enhances the educational experience of science undergraduates and attracts and retains talented students to careers in science. However, access to undergraduate research experiences is few and often limited to high performing students. Course-based undergraduate research experiences (CUREs) engage more students in research-based learning. In this study a network-based CURE was …

Making Science-Inquiry Learning Accessible For Students With Complex Support Needs, Sarah Koebley, Shawnee Wakeman, Lindsay Ruhter, David Pugalee, Meagan Karvonen
Journal of Science Education for Students with Disabilities
Inquiry learning through engagement with scientific practices has proven to be an effective instructional practice for general education students. Although students with complex support needs (CSN) are required to have access to the same grade-appropriate academic content in science as their peers without CSN, it remains a challenge for special education teachers to design instruction around student inquiry and science conceptual understanding. The 5E Science Education for Special Educators (5E-SESE) Model combines three well-established conceptual constructs (three-dimensional science standards, Universal Design for Learning [UDL], and the 5E Model) to support special educators in delivering quality science instruction. With the 5E …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Quantitative reasoning (QR) is a key skill for undergraduate biology education. Despite this, many students struggle with QR. Here, we use the theoretical framework of student noticing to investigate why some students struggle with QR in introductory biology labs. Under this framework, what students notice when given new information and data influences how they process this information and connect it with other events to form new conceptions. Students must mentally isolate given features, create mental records of those features, and identify features or objects that they connect to existing knowledge. Identifying these features or objects is thus critical since they …

Pharmacy Faculty Articles and Research
The peer-reviewed literature on the adjustment or curving of assessments in health profession programs is almost non-existent. This communication aims to present potential methods of grade adjustment for individual questions or entire assessments. Simulated data for a 25-item assessment were used as an example to analyze the effects of different methods of grade adjustment on students’ scores. Grade adjustments were made by adjusting the points for individual questions or the scores for the entire assessment. Adjustment for the individual questions was carried out by dropping the question, adding points to those who missed the question, or adding a bonus point …

Curated undergraduate research experiences have been widely used at colleges and universities for decades to build student interest, technical preparation, and confidence in the pursuit of scientific careers. Educators often employ standardized survey instruments to evaluate learning outcomes for research experiences, but many of these assessments consider only technical skill development and career interests and are not rooted in discrete pedagogical theories. As higher education aims to create inclusive and equitable learning experiences for students, we argue that pedagogical assessment tools for undergraduate research experiences need to expand to consider outcomes such as increased science literacy, confidence in relational “soft” …

Science Identity Development Among Minoritized Students In Professional Stem Student Organizations: A Basic Qualitative Study, Michaela Friedrichova Holtz
Dissertations of Practice
Despite national efforts to broaden participation in STEM, underrepresented minoritized (URM) students continue to face systemic barriers to persistence and degree completion. While many intervention programs focus on academic preparedness, less is known about the role of co-curricular experiences—specifically professional STEM student organizations—in shaping science identity, a key predictor of persistence and success. This qualitative study explored how involvement in race- and gender-based STEM student organizations at a public research university in the Midwest influenced URM students’ science identity development, persistence in STEM majors, and career aspirations. Using the science identity framework developed in 2007 by Carlone and Johnson, semi-structured …

Examining Student Understanding Of Series Convergence Using Script Writing, Eduardo Torres Manzanarez
Mathematics Dissertations - Archive
This exploratory study investigates second-semester calculus students’ understanding of series convergence using both nonscripting and scripting-based tasks. Researchers recognize that students encounter difficulties with learning series, including series convergence, and that there is a need for more meaningful tasks that aid students’ learning of series. Script writing, used mainly with prospective mathematics teachers, can be used to explore mathematical understandings. Thus, this study examines how script writing, in the form of a scripting task, elicits students’ understanding of series convergence in contrast to nonscripting-based tasks to determine the potential of script writing in assessing this student understanding. We examine students’ …
