The Role Of Perceived Academic And Peer Support In Mitigating Imposter Syndrome Among Adhd Students, Eden Morley Dr

Journal of Science Education for Students with Disabilities

Background: Attention-Deficit/Hyperactivity Disorder (ADHD) in higher education is associated with significant executive functioning deficits and performance inconsistencies. These challenges, alongside heightened rejection sensitivity, may predispose students to the Imposter Phenomenon (IP)—the persistent belief that one’s success is undeserved. While social and academic supports are known to buffer psychological distress, their specific role in mitigating IP within the ADHD student population remains under-researched.

Objectives: This study investigated the severity of IP among undergraduate students with ADHD and examined the protective roles of Perceived Social Support (PSS) and Perceived Academic Support (PAS), while exploring gender as a potential moderator.

Methodology: A cross-sectional …

Sitting Together: How Proximity Impacts The Classroom Success Of Undergraduate Women In Engineering, Cassandra M. Savukinas, Kayla D. Taylor, Ashley Lear

Feminist Pedagogy

Despite increased efforts, the engineering field remains predominantly male, particularly within higher education environments. Seating arrangements in the classroom for female undergraduate engineering students can greatly impact their comfort, participation, and academic performance in the classroom. In a 2025 study, it was found that male and female students have differing experiences related to comfort, participation, and academic performance when seated near other students of the same gender (Savukinas et al., 2025). Faculty can help students succeed by understanding how seating dynamics impact students’ experiences in the classroom. By allowing students to choose their own seating arrangements and creating interactions in …

Comparable Outcomes, Divergent Learning Pathways: Comparing Metacognitive Reflection And Practice Problems In Organic Chemistry, Jitendra D. Belani

College of Life Sciences Faculty Papers

Organic Chemistry I presents significant challenges for students, requiring both conceptual understanding and effective study strategies. Two commonly used approaches to support learning are structured practice problems and metacognitive reflection activities; however, these strategies are rarely compared directly within the same course context. In this study, students enrolled in a postbaccalaureate Organic Chemistry I course (n = 31) were randomly assigned to one of two low-stakes interventions: weekly practice problem sets or structured reflection surveys focused on study strategies. Student performance was evaluated using three midterm examinations, a cumulative final exam, and overall course grades, along with measures of participation. …

Using “You” As A Subject In Biology Assessment Questions: Examining Student Preferences For Second-Person Framing, Noelle Clark, Kate Hill, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

In college biology courses, exams and quizzes are often used to assess students’ knowledge and performance. Since assessments are a crucial part of biology classes, there has been a wide range of work examining how assessment questions are written, revealing that small changes in how such questions are worded may have large impacts on students’ reading comprehension and performance. One aspect that instructors consider when writing a question is subject framing, i.e., which individual, if any, is being placed as the focal point of the question. In this study, we focus on the following subject framings, an authentic scientist, a …

Coupled-Pendulum Modeling In An Ode Class: An Assignment On Fourier-Initialized Gradient Descent In Machine Learning, Huy Truong, Andrew Bennett

CODEE Journal

As data-driven methods are increasingly used in science and engineering, students benefit from learning to integrate machine learning techniques with traditional mathematical modeling. We present a hands-on extra-credit assignment for an undergraduate ordinary differential equations (ODE) course that enables students to compare classical analytical methods with data-driven approaches on the same physical system. Using a coupled-pendulum system---two pendulums connected by a spring---with real experimental data acquired via video tracking of a real physical setup, students work through three models in a guided Jupyter notebook with all code provided. First, they fit a neural network with Fourier features as a purely …

How Leadership Can Support Inquiry-Based Learning In Myp Mathematics, Paul A. Thompson

Graduate Teacher Education

This literature review examined the research question: “How can instructional leadership prepare IB MYP Mathematics teachers to implement inquiry-based learning (IBL) effectively?” The review defined IBL within the International Baccalaureate Middle Years Program (IB MYP), then explored how inquiry in the MYP was designed to promote better student outcomes in conceptual understandings, interdisciplinary learning, and real-life connections. The role of the MYP Coordinator (MYP), the pedagogical leader of this program, is central to answering the questions that focus on leadership. The literature also examined the benefits and barriers of implementing inquiry-based mathematics instruction. The findings suggested that effective IBL improves …

A Differential Equation–Based Epidemiological Model Of Post-Operative Chronic Pain In Scoliosis Patients With Data-Driven Analysis, Paige Zhu, Padmanabhan Seshaiyer

CODEE Journal

Chronic post-surgical pain (CPSP) is a common and often overlooked complication following surgical correction of idiopathic scoliosis, impacting long-term patient wellbeing despite improvements in surgical outcomes. This project introduces a novel epidemiological framework to model the progression of CPSP using a compartmental structure. By applying a coupled system of nonlinear differential equations, we simulate pain trajectories over time and assess the effectiveness of surgical interventions. The model is implemented for a single-cohort population and extended to a two-cohort design to compare outcomes between Posterior Spinal Fusion (PSIF) and Vertebral Body Tethering (VBT) procedures. Further stratification by patient age enables us …

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, Teaching - Volume 4, Stephen Demeo

Publications and Research

In Volume 4, the last book of the series, I continue the argument for greater parity between conceptual knowledge—the "what" of science—and methodological knowledge—the "how" of science—but in the context of teacher instruction. To this end, two literature reviews are presented: One on how students build confidence, specifically regarding the reliability or consistency of measurement or results, and the other on scientific uncertainty. Research studies focusing on student misconceptions are summarized and organized from the elementary to the college level. These literature reviews describe invaluable ways for teachers to improve their instruction, while providing examples of experiments that can be …

Trattato Dell’Alcibra Amuchabile (Anonimo): A Guided Translation, Gary Towsley, Olympia Nicodemi

Geneseo Authors

The Trattato dell’Alcibra Amuchabile is a pre-modern algebra text from c. 1365. It is written in a Tuscan dialect of Italian and is situated in the abbacus school tradition, schools that taught the mathematics needed for a mercantile society. Like all the algebra written in Italy at the time, it was inherited from al-Khwarizmi and, like his, written with no symbols—no x’s, y’s, plus signs, etc. It was what is sometimes called “rhetorical algebra.”  There is very little source  material available in English from this important era in the history of algebra. This book helps fill that gap. …

The goal of the project is to develop a theoretically grounded and empirically supported instructional approach that builds on students’ experiences in the calculus sequence to engage them in the reinvention of the rigorous foundations of the calculus. An essential aspect of this foundation is the completeness of the real numbers. Drawing on the didactical phenomenology heuristic from the theory of Realistic Mathematics Education (RME), we conducted an iterative instructional design study focused on the completeness axiom. The work proceeded in two phases. First, we conducted …

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, Uncertainty And Error - Volume 3, Stephen Demeo

Publications and Research

Volume 3 explores the essential roles of uncertainty and error in scientific experimentation. It distinguishes between scientific error and scientific uncertainty: Scientific error refers to the difference between an experimental value and an accepted literature value, as well as the difference between data points in an x-y scatter plot and a predicted trendline. Scientific uncertainty, on the other hand, is associated with doubt arising from instrument limitations, variability within a data set, and psychological factors. Human error is set apart as mistakes or blunders, not to be conflated with scientific error.

Of utmost importance to the scientific investigator is the …

Highly Confident But Slightly Uncertain: A Long Overdue Reinvention Of The School Scientific Method, The X - Volume 1, Stephen Demeo

Publications and Research

In Volume 1, I critique the traditional School Scientific Method—an oversimplified, underdeveloped, and short, stepwise process—and argue for a more authentic, detailed, and rigorous approach to experiment-based scientific inquiry in education. I briefly explain the historical roots of the School Scientific Method, its benefits in increasing the exposure of experimental science to the masses, and its limitations in fostering more authentic scientific thinking and experimental practice.

In place of this traditional and problematic method, I introduce a graphic organizer called sciXpsy to foster both big-picture and detailed scientific thinking. The heuristic combines scientific concepts and methodology with the psychology of …
