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. …

Equitable Pre-College Engineering Education: Teaching With Racism In Mind, James Holly Jr

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

Engineering educators must consider how the cultural backgrounds of students coincide (or diverge) with the epistemological and ontological formation of an engineer. Hence, this work is presented as an exhortation to engineering educators, particularly in a pre-college context, to critically evaluate how race-conscious pedagogies can be exerted in this field. In this autoethnographic study, I convey my attempt to teach engineering with explicit consideration of the sociopolitical context of the Black male youth I taught. As a Black male, I have an insider perspective into the realities that must be navigated to succeed in a racialized society, where Black males …

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 …

The Car (Confront, Address, Replace) Strategy: An Antiracist Engineering Pedagogy, Amman Fasil Asfaw

Master's Theses

The CAR (confront, address, replace) Strategy is an antiracist pedagogy aiming to drive out exclusionary terminology in engineering education.

“Master-slave” terminology is still commonplace in engineering education and industry. However, questions have been raised about the negative impacts of such language. Usage of exclusionary terminology such as “master-slave” in academia can make students—especially those who identify as women and/or Black/African-American—feel uncomfortable, potentially evoking Stereotype Threat (Danowitz, 2020) and/or Curriculum Trauma (Buul, 2020). Indeed, prior research shows that students from a number of backgrounds find non-inclusive terminologies such as “master-slave” to be a major problem (Danowitz, 2020). Currently, women-identifying and gender …

The Ingenuity Of Everyday Practice: A Framework For Justice-Centered Identity Work In Engineering In The Middle Grades, Angela M. Calabrese Barton, Kathleen Schenkel, Edna Tan

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.

Equitizing Engineering Education By Valuing Children’S Assets: Including Empathy And An Ethic Of Care When Considering Trade-Offs After Design Failures, Pamela S. Lottero-Perdue, John Settlage

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

The broad case being made in this paper is that recognizing student assets—rather than focusing on deficits—is essential for making engineering education more equitable. The paper begins with our exploration of an epistemic practice of engineering, ‘‘making trade-offs,’’ as enacted by kindergartners after experiencing design failure and during redesign. We then acknowledge through a reexamination of data that our understanding of children’s grappling about a trade-off was incomplete without considering another asset that children brought to the design experience: ‘‘enacting empathy and an ethic of care.’’ We argue for the inclusion of this asset as an epistemic practice of engineering. …

Reflections On Asset-Based Pre-College Engineering Education To Promote Equity: An Introduction To The Special Issue, Lee Martin, Kristen B. Wendell

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

In our call for proposals, we argued that engineering education is in need of a paradigm shift that takes students’ assets as epistemologically primary to our conception of what engineering, and engineering education, can and should be. The 12 papers collected in this special issue show how a focus on youth assets can realign engineering education to be more humane, more inclusive, and just as meaningful as that of a traditional model. The papers offer both theoretical argumentation and empirical evidence to support their answers to the question of how asset-based approaches can improve engineering education. An emergent theme in …

Machine Learning Meets Internet Of Things: From Theory To Practice, Bharath Sudharsan, Pankesh Patel

Publications

Standalone execution of problem-solving Artificial Intelligence (AI) on IoT devices produces a higher level of autonomy and privacy. This is because the sensitive user data collected by the devices need not be transmitted to the cloud for inference. The chipsets used to design IoT devices are resource-constrained due to their limited memory footprint, fewer computation cores, and low clock speeds. These limitations constrain one from deploying and executing complex problem-solving AI (usually an ML model) on IoT devices. Since there is a high potential for building intelligent IoT devices, in this tutorial, we teach researchers and developers; (i) How to …
