Purdue Epics And Habitat For Humanity Partnership - Service-Learning For Over 20 Years, Trevor A. Drouillard, Sue Hunter Dec 2018

Purdue Epics And Habitat For Humanity Partnership - Service-Learning For Over 20 Years, Trevor A. Drouillard, Sue Hunter

Engagement & Service-Learning Summit: Connecting Through Listening & Scholarship

For over twenty years, the Lafayette affiliate of Habitat for Humanity has partnered with the Purdue University EPICS program to connect students to real-world problems where they can learn engineering through experience. Past projects have focused on improving material storage methods, enhancing volunteer safety, developing energy-efficient building designs, and optimizing operational efficiency at Habitat for Humanity locations. The partnership is mutually beneficial for Habitat for Humanity – which benefits from the products students deliver – and for students – who learn how to apply engineering to real-world design. This poster represents a summary of what the EPICS – Habitat for Humanity partnership has produced ...

Collaborative Product–Service Approach To Aviation Maintenance, Repair, And Overhaul. Part I: Quantitative Model, Cassio Dias Goncalves, Michael Kokkolaras Nov 2018

Collaborative Product–Service Approach To Aviation Maintenance, Repair, And Overhaul. Part I: Quantitative Model, Cassio Dias Goncalves, Michael Kokkolaras

Journal of Aviation Technology and Engineering

This two-part paper proposes a new collaborative approach to airframe maintenance, repair, and overhaul (MRO). A quantitative model is introduced in Part I to represent the business relationships between original equipment manufacturers (OEMs) and MRO enterprises. In Part II, the presented model is used to assess potential financial benefits obtained by each of these stakeholders as a result of the collaboration.

The quantitative model is built to capture the main dependencies between an independent MRO enterprise operating in South America and its interactions with three major airframe OEMs. Interviews were conducted with MRO and OEM professionals to identify the most ...


Implementing Ngss Engineering Disciplinary Core Ideas In Middle School Science Classrooms: Results From The Field, Jessica Gale, Jayma Koval, Mike Ryan, Marion Usselman, Stefanie Wind Nov 2018

Implementing Ngss Engineering Disciplinary Core Ideas In Middle School Science Classrooms: Results From The Field, Jessica Gale, Jayma Koval, Mike Ryan, Marion Usselman, Stefanie Wind

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

With the inclusion of engineering disciplinary core ideas (DCIs), the Next Generation Science Standards (NGSS) position engineering as a new priority in K–12 science classrooms. This paper reports findings from the implementation of SLIDER, a problem-based learning 8th grade physical science curriculum that integrates engineering and physical science core ideas. As a culminating engineering design challenge, the SLIDER curriculum asks students to apply their understanding of energy, motion, and forces to design an automatic braking system for a robotic truck. The paper describes the curriculum and synthesizes findings from an array of data sources including student design interviews, written ...

Habitat For Humanity: A Student-Led Service Trip To Thailand, Amber Reiff

Purdue Journal of Service-Learning and International Engagement

Amber Reiff started volunteering with Habitat for Humanity in high school and joined the Purdue Student Chapter as a freshman in 2014. During her sophomore year, she became more involved and held the position of Vice President of Development. While serving in this role, she planned on-campus advocacy events and recruited volunteers for Saturday site builds. In 2017, she traveled to Lampang, Thailand, over spring break with a group of like-minded students striving to make a difference. In this article, she shares her experiences on this trip and explores the impact of her participation. Beyond this trip, she has continued ...

They partnered with the Indiana School for the Blind and Visually Impaired (ISBVI) to develop a braille transcription device and web application that converts braille to print in real time.


Search And Review Of The Literature On Engineering Design Challenges In Secondary School Settings, Matthew Lammi, Cameron Denson, Paul Asunda Nov 2018

Search And Review Of The Literature On Engineering Design Challenges In Secondary School Settings, Matthew Lammi, Cameron Denson, Paul Asunda

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

Engineering design activities offer the promise of enhanced learning and teaching in pre-college science, technology, engineering, and mathematics (STEM) settings. The wide variation and lack of coherence in research and practice concerning pre-college engineering design challenges necessitates an investigation of the literature. The overarching research question guiding this search and review of literature was, ‘‘How are engineering design challenges conceptualized in pre-college environments?’’ A search and review coupled with iterative thematic analysis was employed to understand and conceptualize the current body of literature on pre-college engineering design challenges. It is anticipated that this review will provide a general picture of ...


Stem Roles: How Students’ Ontological Perspectives Facilitate Stem Identities, Dina Verdín, Allison Godwin, Monique Ross Nov 2018

Stem Roles: How Students’ Ontological Perspectives Facilitate Stem Identities, Dina Verdín, Allison Godwin, Monique Ross

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

Educational researchers have explored the importance of performance, recognition, and interest in establishing and maintaining a STEM identity. Research has also demonstrated that the ways students describe themselves and how they participate in STEM communities can provide insight into their role identity salience; however, there has been little work to explore the ontological beliefs of students about STEM people and how this influences their ability to see themselves as possessing a STEM identity. This research explores the ontological beliefs of high school students, with specific attention to the ways in which they describe what constitutes a math person, science person ...

Hypothesis Paper: Mechanism For Primary Blast Induced Traumatic Brain Injury With Minimal Head Motion, Charles F. Babbs Oct 2018

Hypothesis Paper: Mechanism For Primary Blast Induced Traumatic Brain Injury With Minimal Head Motion, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

Transit of the human skull by blast waves produces diffuse brain injury. The exact mechanisms are unknown. This paper describes plausible mechanisms in which steep intracranial pressure gradients, demonstrated in prior computational models of blast-skull interaction, produce subsequent deformation and motion of the whole brain within the skull, without obvious movement of the head. Equations of motion are derived to describe the acceleration, velocity, and relative position of both the skull and the brain in response to known extracranial and intracranial pressures both during and several hundred milliseconds after blast wave passage. A finite element model is solved to visualize ...


One Root, Many Trees: Reviving Collections Practices, Kevin Farley, Emily Davis Winthrop, Ibironke Lawal, Patricia Sobczak Sep 2018

One Root, Many Trees: Reviving Collections Practices, Kevin Farley, Emily Davis Winthrop, Ibironke Lawal, Patricia Sobczak

Charleston Library Conference

Collections are undergoing intense change and pressure from technology, budgetary uncertainties, and emerging perspectives on future approaches. Our case study—drawn from our experiences as collections librarians—examines these complex issues facing academic collections, large or small, across the profession. Through the development of “collections of distinction” within the local collection, collaborations and scholarly partnerships with colleagues and faculty, and advocacy for the importance of dedicated oversight to ensure that collections investments fulfill the academic mission, we explore possible solutions to the complicated issues defining contemporary collections practices.
