Tutoring With Adhd In The Writing Center, Ghada Seifeddine Jan 2022

Tutoring With Adhd In The Writing Center, Ghada Seifeddine

Purdue Writing Lab/Purdue OWL Graduate Student Presentations

The presentation aims to unwrap the stories of writing center tutors with Attention Deficit Hyperactivity Disorder (ADHD), to better understand what happens in their sessions, and to explore how they conduct tutoring with different clients. This talk presents data from a pilot survey of existing tutors and clients, in conjunction with case study interviews with a current peer tutor and client, both with ADHD. Findings focus on ways to empower tutors and writers with ADHD, further advocate for writer and tutor accessibility, and help administrators and practitioners advance tutor education around disability literacy in writing centers.

Cultivating Cultural Capitals In Introductory Algebra-Based Physics Through Reflective Journaling, Khanh Q. Tran, Ana Maria Barrera, Kim Coble, Mireya Arreguin, Marissa Harris, Alex Macha-Lopez, Michaela Perez, Alegra Eroy-Reveles

Purdue University Libraries Open Access Publishing Fund

At a large, diverse, hispanic-serving, master’s-granting university, the Alma Project was created to support the rich connections of life experiences of science, technology, engineering, and mathematics (STEM) students that come from racially diverse backgrounds through reflective journaling. Utilizing frameworks in ethnic studies and social psychology, the Alma Project aims to make learning STEM inclusive by affirming the intersectional identities and cultural wealth that students bring into STEM classrooms. Approximately once per month students who participate in the Alma Project spend 5–10 min at the beginning of class responding to questions designed to affirm their values and purpose for studying STEM …

Indiana STEM Education Conference

Research shows that Black and Hispanic workers continue to be under-represented in the STEM (science, technology, engineering and mathematics) workforce. Purdue Polytechnic High School (PPHS) was established to achieve broader academic and workforce goals. PPHS fosters a sense of community for students by fostering diversity in teachers, focusing on project-based learning, and providing students with a constructive and collaborative space to explore their passions. To support career readiness, the school personalizes student learning and focuses on enhancing student problem-solving skills through a structured group engagement program called "passion projects". The school meets the academic requirements of the state while providing …


Reflecting On Recurring Failures In Iot Development, Dharun Anandayuvaraj, James C. Davis Jan 2022

Reflecting On Recurring Failures In Iot Development, Dharun Anandayuvaraj, James C. Davis

Department of Electrical and Computer Engineering Faculty Publications

As IoT systems are given more responsibility and autonomy, they offer greater benefits, but also carry greater risks. We believe this trend invigorates an old challenge of software engineering: how to develop high-risk software-intensive systems safely and securely under market pressures? As a first step, we conducted a systematic analysis of recent IoT failures to identify engineering challenges. We collected and analyzed 22 news reports and studied the sources, impacts, and repair strategies of failures in IoT systems. We observed failure trends both within and across application domains. We also observed that failure themes have persisted over time. To alleviate …

The Bilingual Code-Switching Profile (Bcsp): Assessing The Reliability And Validity Of The Bcsp Questionnaire, Daniel J. Olson Jan 2022

The Bilingual Code-Switching Profile (Bcsp): Assessing The Reliability And Validity Of The Bcsp Questionnaire, Daniel J. Olson

School of Languages and Cultures Faculty Publications

Significant variation exists in bilinguals’ experiences with code-switching, from dense code-switching in multiple interactional contexts to minimal switching. Although recent research has demonstrated that a bilingual’s experience with code-switching is a crucial factor for determining both linguistic and cognitive behaviors, there currently is no commonly accepted method of measuring of a bilingual’s code-switching practices. Responding to this need, this paper presents a new tool to assess a bilingual’s experience and engagement with code-switching — the Bilingual Code-Switching Profile (BCSP) — and assesses its validity and reliability. The BCSP incorporates a multifaceted conceptualization of code-switching experience, drawing on previous research in …
