Funds Of Knowledge As Pre-College Experiences That Promote Minoritized Students’ Interest, Self-Efficacy Beliefs, And Choice Of Majoring In Engineering, Dina Verdín, Jessica M. Smith, Juan Lucena

Journal of Pre-College Engineering Education Research (J-PEER)

Pre-college experiences both inside and outside of the classroom inform students’ interest in science, technology, engineering, and mathematics (STEM)-related activities, help them evaluate their knowledge and skills in various tasks, and shape their perceptions of themselves as individuals who can participate in STEM. Yet little empirical research examines the valuable pre-college knowledge, practices, and skills that minoritized students acquire through their home experiences and how they can support students’ transition into an engineering pathway. This study addresses this gap by investigating how students’ funds of knowledge support their interest in engineering, self-efficacy beliefs, and certainty of pursuing an engineering major. …

Providing An Elementary School Environment That Encourages Girls To See Their Place In The Stem Fields, Hannah Borchardt

Innovations and Critical Issues in Teaching and Learning

For many years, women have been underrepresented in the Science, Technology, Engineering, and Mathematics (STEM) fields at the collegiate and professional levels. The two primary reasons for this underrepresentation are the influence of gender stereotypes and biases surrounding STEM and the lack of female role models in the STEM field. Elementary educators must do what they can to address these issues in an effort to allow girls to see their place in STEM. To help counter the influence of gender stereotypes and biases in STEM, elementary educators should integrate STEM into the classroom for all students to participate and have …

Pandemic Pivot: Designing A Participatory Simulation To Support Social Distancing And Remote Learning, K. K. Lamberty, Paul Friederichsen, Audrey Le Meur, Joseph Moonan Walbran

Computer Science Publications

Participatory simulations usually aim to bring simulations off screen into a shared physical space with people acting as agents in the simulation. In this paper, we describe considerations and design decisions related to creating a participatory simulation for use in learning settings with restrictions imposed due to the COVID-19 pandemic where typical classroom interactions were no longer allowed. We describe how our design decisions might help children both “dive in” and “step out” to understand more about pollinators and the prairie in spite of various restrictions on how exactly they can interact with each other. Our simulation, Buzz About, uses …

Teacher Led Tier Two Intervention To Increase Student Academic Achievement, Cynthia Shepherd

The Social Support Networks Of Students Who Identify As Black And Latino/A/X In Stem And Sbe Graduate Programs At Predominantly White Institutions, Kristi A. Tullis

Dissertations

Graduate students from historically underrepresented minority (URM) groups (those who identify as Black/African-American, Hispanic/Latino/a/x, Native American, Native Hawaiians/Pacific Islanders and/or Alaska Natives) encounter systemic and institutional hindrances to degree completion when enrolled in STEM doctoral programs at predominantly white institutions (Guiffrida & Douthit, 2010). Support networks have been identified as an important component for retention and success for graduate students from URM groups (Carlone & Johnson, 2007; Clewell, 1987; Johnson-Bailey, Valentine, Cervero, & Bowles, 2008; Joseph, 2012; Sweitzer, 2009). This study investigates the composition and structure of URM graduate students’ support networks, where their support comes from, in what capacity, …

Theoretical Study Of Mach Number And Compressibility Effect On The Slender Airfoils, Abrar Hoque, Masudar Rahman, Ashabul Hoque

Applications and Applied Mathematics: An International Journal (AAM)

Theoretical development of the velocity potential equation for compressible flow and its various consequences has been presented. The geometrical interpretation of potential equation and conformal mapping technique are discussed where the mappings link the flow around a circular cylinder of a slender airfoil. The lift and drag coefficients are determined for the slender airfoils based on the Mach number and compressibility effects. The calculated lift coefficients show that with the increasing of attack angle it increases linearly and a higher lift coefficient is found for a smaller Mach number for any certain attack angle. Similarly, the drag profiles are determined …

Real-Life Conundrums In The Struggle For Institutional Transformation, Julia Mcquillan, Nestor Hernandez

Department of Sociology: Faculty Publications

Intersecting systems of inequality (i.e., gender and race/ethnicity) are remarkably resistant to change. Many universities, however, seek National Science Foundation Institutional Transformation awards to change processes, procedures, and cultures to make science, technology, engineering, and mathematics (STEM) departments more inclusive. In this article we describe a case study with observations for eight years of before (2000–2007), five during (2008–2013), and seven after (2014–2020) intensive efforts to increase women through reducing barriers and increasing access to women. Finally, we reflect on flawed assumptions built into the proposal, the slow and uneven change in the proportion of women over time, the strengths …

Journal of Global Education and Research

Valuing constitutes an important aspect of mathematics pedagogy and hence student learning outcomes. This study surveyed 416 students from Cape Coast, Ghana to explore what senior high school students in this country in West Africa valued in their study of mathematics. The data collected were analyzed using principal component analysis. The results suggest that Ghanaian senior high school students found connections, understanding, fluency, learning technologies, feedback, instructional materials, open-endedness and problem-solving important in their mathematics learning. Implications of the findings for curriculum delivery in mathematics and future research opportunities are also discussed.

Biodiversity Monitoring And Volunteer Motivations: A Case Study On The Imagined Communities Of Citizen Scientists In Meinung, Taiwan, Serena May Calcagno

Master's Projects and Capstones

The Asia Pacific’s biodiversity is under threat. One significant step that can improve conservation is gathering data on what species exist in different areas over time, which can provide insight into ecosystem health. This is especially important in biodiversity hotspots, where high levels of endemism and anthropogenic risk overlap. Though it is one of the few places in the Pacific not classified as a biodiversity hotspot, Taiwan has an unusually high saturation in terms of biodiversity data points. Investigating the motives of biodiversity monitoring volunteerism is already a topic of growing scholarly interest, but relatively few studies have focused on …

Setting Empirically Informed Policy Benchmarks For Physical Science Teaching, Elizabeth B. Lewis, Ana Rivero, Lyrica L. Lucas, Aaron Musson, Brandon Helding

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge (SMK) and resulting misconceptions of chemistry and physics concepts. Findings were compared with state-level science teacher certification policies. Participants had either: (a) completed a master's level teacher preparation program with an undergraduate degree in science, (b) completed an undergraduate teacher preparation program with a minor degree or more in science, or (c) were undergraduate students enrolled …

Temperature-Sensitive Holograms With Switchable Memory, Muhammad Irfan Dr, Suzanne Martin Dr, Izabela Naydenova Prof

Articles

Abstract

Herein, the dynamics and reversibility of temperature-induced changes in volume phase holographic gratings (VPHGs) recorded in the low-toxicity self-processing photopolymer poly(N-isopropyl acrylamide) (poly-NIPA) are reported on. Transmission and reflection gratings are exposed to temperatures ranging 8–60 °C to study the effect of temperature on their properties. First, the role of the photopolymer chemical composition is investigated by comparing layers containing NIPA with those containing acrylamide (AA) and measuring the normalized diffraction efficiency (DE) at 60 °C; higher thermal sensitivity is observed for poly-NIPA gratings (24% drop) versus low sensitivity for AA gratings (2% increase). The impact of …

Journal of Pre-College Engineering Education Research (J-PEER)

Inequities in opportunities to learn and become in engineering, especially for minoritized youth, are enduring and systemic. How students experience engineering education, through curriculum, pedagogy, and teacher/student interactions, all shape opportunities for identity development. In this paper we draw upon cultural studies and critical ethnography to explore how and why students engage in engineering for sustainable communities and its relationship to their identity work. We ground our work in a justice-centered asset-based stance that centers how people’s lived lives and community wisdom yield powerful forms of cultural knowledge/practice relevant to learning and engaging in science, technology, engineering, and mathematics. We …

Exploring The Nature Of The Co-Emergence Of Students' Representational Fluency And Functional Thinking, Nigar Altindis

Dissertations - ALL

Abstract In this dissertation, I explore ways to support secondary school students' meaningful understanding of quadratic functions. Specifically, I investigate how students co-developed representational fluency (RF) and functional thinking (FT), when they gained meaningful understanding of quadratic functions. I also characterize students' co-emergence of RF and FT on each representation (e.g., a graph, a symbolic equation, and a table) and across multiple representations. To accomplish these goals, I employed a design research methodology: a teaching experiment with eight Turkish-American secondary school students in an after-school context at a Turkish Community Center. I constructed the design principles and design elements for …

Modeling Functions: Modified Falling Ladder Task, Nakia Salam

Symposium of Student Scholars

Modeling Functions: Modified Falling Ladder Task

By the time students graduate from high school, the knowledge of functions has shifted from a conceptual understanding to a procedural approach, where the understanding of functions is based upon memorized computational steps that can’t be modeled. A focus on the computational aspect of functions can have a long-term effect on students’ ability to understand the meaning of functional relationships, negatively affecting their overall ability to reason mathematically. Without educators making a conscious decision to recognize the value of modeling and force its’ inclusion, there are few opportunities to experience the application of functional …

A Study Examining The Safety And Efficacy Of Ferric Carboxymaltose In A Large Pediatric Cohort, Chandni Dargan Md, David Simon Do

Research Days

Background: Iron deficiency anemia (IDA) is common in the pediatric population with varying high-risk factors. Intravenous (IV) iron supplementation has become more desirable in patients with moderate to severe anemia and in patients who are either unresponsive to or have adverse side-effects secondary to oral iron. Iron sucrose and Iron dextran have been traditionally used in pediatrics while ferric carboxymaltose (FCM) has only been FDA approved in adults. One of the major advantages of FCM is the ease of dosing and efficacy. Though FCM was approved for adults in 2013 and there have been no safety concerns, it is not …

Portable Low Field Strength Mri: Preliminary Experience In Neonates And Children, Johnston Fite

Research Days

Variability In Blood Gas Levels During Non-Invasive Ventilatory Support Following Planned Extubation And Association To 36-Week Bronchopulmonary Dysplasia In Preterm Neonates, Michelle Klueppelberg

Research Days

Background: Despite shifts to non-invasive support, as of 2012, 87% of preterm infants admitted to the neonatal intensive care unit (NICU) continued to receive some form of invasive mechanical ventilation1 . As a result, research around how prolonged respiratory support may impact the development of chronic lung disease, specifically bronchopulmonary dysplasia (BPD) has flourished. To date, literature has established associations between the time on invasive mechanical ventilation and incidence BPD2,3. Resulting in the development of standardized extubation strategies and bringing with them objective measures of extubation readiness4,5. Yet, due to their volatile conditions, some neonates will inevitably need to be …

Antibiotic Durations For Skin And Soft Tissue Infections In Pediatric Urgent Care Clinics, Megan Hamner

Background: Skin and soft tissue infections (SSTIs) are the second most common diagnosis leading to pediatric antibiotic prescriptions in the outpatient setting after respiratory diagnoses. However, most antibiotic stewardship programs have mainly focused on the latter. Children seen in the ambulatory setting for SSTIs often receive >7 days of antibiotics, although current society guidelines recommend 5-7 days for most diagnoses.

Objectives/Goal: To determine the baseline percentage of patients receiving antibiotic prescriptions for >7 days for SSTIs in Children’s Mercy urgent care clinics (UCC)s and to evaluate factors that influence providers towards longer durations.

Methods/Design: We built a report that extracted …

Developing An Inquiry-Based Laboratory Project For Chem 142l Course At Bsu, Manuel Pina

Honors Program Theses and Projects

In addition to content knowledge, critical and independent thinking, scientific reasoning, and problem-solving skills are essential in preparing next generation of successful workforce. Since one of the biggest advantages of STEM disciplines is a “must-have” hands-on laboratory experience, it is intuitive to exploit this learning space to reinforce afore-mentioned skills. In this context, project-based (PBL) or inquiry-based (IBL) laboratory experiences are rapidly becoming mainstream pedagogical choice for many STEM instructors across United States.^[1-4] PBL, and IBL are learning experiences that offer students an opportunity to experience realistic scientific process of discovery through carefully designed inquiry-driven and/or open-ended investigative laboratory …
