Assessing Industry-Critical Skill Development In Engineering Technology Capstone Courses, Rustin Webster, Matthew Turner Jan 2024

Assessing Industry-Critical Skill Development In Engineering Technology Capstone Courses, Rustin Webster, Matthew Turner

School of Engineering Technology Faculty Publications

To meet industrial expectations, engineering and engineering technology (ET) graduates are expected to possess the critical competencies of design, problem-solving, communication, and teamwork. However, industry stakeholders and academic studies routinely identify these as skills gaps: areas graduates need to develop to a higher standard or are currently lacking when entering the work force. To address this issue, many undergraduate programs in the United States have implemented a comprehensive and integrative experience at the end of an academic program, often called a capstone course(s). The rate of adoption has grown such that approximately three-quarters of all undergraduate and graduate institutions include …


Maintenance Decision Criteria In Facility Management, Deniz Besiktepe, Mehmet E. Ozbek, Rebecca Atadero Jan 2024

Maintenance Decision Criteria In Facility Management, Deniz Besiktepe, Mehmet E. Ozbek, Rebecca Atadero

Bowen School of Construction Faculty Publications

This research report investigates how facilities management (FM) professionals make decisions about building maintenance, a central responsibility in FM that accounts for a majority of operational effort and costs. Given the complexity of maintenance activities and the many conflicting factors involved (like cost, safety, condition, schedules, and compliance), the study aims to identify and rank key criteria that influence maintenance decision-making. To do this, the authors conducted a comprehensive literature review and a nationwide survey of facilities management professionals from IFMA and APPA. The result is a set of fundamental decision criteria (e.g., health and safety, code compliance, condition, cost, …


Needs Assessment – National Repository For Nsf Agep Deliverables, Christie Sahley, Megan Sapp-Nelson, Donna Ferullo, Linda Mason, Hanzi Xie Jan 2024

Needs Assessment – National Repository For Nsf Agep Deliverables, Christie Sahley, Megan Sapp-Nelson, Donna Ferullo, Linda Mason, Hanzi Xie

Libraries Faculty and Staff Scholarship and Research

This white paper proposes the establishment of a National Repository for NSF Alliance for Graduate Education and the Professoriate (AGEP) Deliverables to address the critical need for preserving and sharing a wide array of materials generated from the AGEP program. Recognizing the challenges of ephemeral storage solutions and the absence of a unified collection mechanism, the paper underscores the repository's role in promoting justice, equity, diversity, and inclusion (JEDI) research. It emphasizes the importance of accommodating diverse data types, enhancing discoverability, and ensuring long-term access to educational materials, policy documents, and research outcomes. Through a comprehensive approach, the proposed repository …


Critical Race Digital Literacy Rubric For Assessing Mis/Disinformation Literacy Instruction Lesson Plans, Melissa Chomintra Jan 2024

Critical Race Digital Literacy Rubric For Assessing Mis/Disinformation Literacy Instruction Lesson Plans, Melissa Chomintra

Libraries Faculty and Staff Scholarship and Research

While librarians have been at the forefront of the fight against fake news, misinformation, and disinformation, offering invaluable guidance and tools through information literacy instruction, there is a noteworthy gap in the adoption of pedagogical approaches rooted in critical theory within mis/disinformation literacy lesson plans. This suggests there may not be well-defined or standardized frameworks for incorporating these theories into library instruction. The enclosed article explores Critical Race Digital Literacy (CRDL) as a pedagogical approach to mis/disinformation literacy education by proposing a rubric for assessing mis/disinformation lesson plans. The rubric is grounded in the principles of critical race theory, emphasizing …


Business Archives As A Tool For Academic Business Researchers, Annette Bochenek, Ilana Stonebraker Jan 2024

Business Archives As A Tool For Academic Business Researchers, Annette Bochenek, Ilana Stonebraker

Libraries Faculty and Staff Scholarship and Research

This paper examines the structure and collections in business archives in order to create a list of suggestions to better prepare researchers seeking historical business data prior to 1970. Four business archivists were chosen for interviews from a variety of industries. The article shares seven tips gained from the interviews, including getting to know what is housed or not housed in the business archive, looking for archives with museum arms, and considering the importance of legal permission as part of the process for utilizing business archives. The authors also explore how business librarians can better support the work of business …


Tracking Information In The Field: An Assessment Of The Information Needs And Services Of A Field Station Library, Thom Gerrish, Scott Martin Jan 2024

Tracking Information In The Field: An Assessment Of The Information Needs And Services Of A Field Station Library, Thom Gerrish, Scott Martin

Libraries Faculty and Staff Scholarship and Research

This project examines field station libraries, an undescribed type of library associated with terrestrial and marine field stations. Field stations typically support ecology, geology, and related disciplines with housing, laboratories, and research facilities, which may include various levels of library support. In summer 2022, researchers, instructors, and staff at the University of Michigan Biological Station were interviewed about the library resources and services they use while working and teaching at the field station. Library resources were used throughout teaching and research activities, with one-shot instruction and in-person reference support as the primary contact points between the library and the field …

Implementing Integrated Stem Forensic And Soil Sciences Lab Activities To Promote Interest In Stem Careers, Mariah K. Stollar Awan, Caroline J. Rakowski Jan 2024

Implementing Integrated Stem Forensic And Soil Sciences Lab Activities To Promote Interest In Stem Careers, Mariah K. Stollar Awan, Caroline J. Rakowski

Indiana STEM Education Conference

We implemented forensic and soil science integrated STEM lab activities with 11 middle school youth at a 4-H day camp at Purdue University. STEM perceived knowledge increased overall for participants. However, the pre- and post-assessments did not show a statistically significant difference. More students also indicated STEM career interest after participating. Because this study was exploratory and had a small sample size, more research on these integrated STEM lab activities should be conducted with larger samples.


Course-Based Undergraduate Research Experiences (Cure) In Engineering Technology, Bill Hutzel, Craig Zywicki, Stephanie M. Gardner Jan 2024

Course-Based Undergraduate Research Experiences (Cure) In Engineering Technology, Bill Hutzel, Craig Zywicki, Stephanie M. Gardner

School of Mechanical Engineering Faculty Publications

Although most universities provide excellent research experiences for outstanding undergraduate students, the number of interested students typically outstrips the supply of faculty and graduate student mentors. Addressing this shortfall is the reason Course-based Undergraduate Research Experiences (CUREs) were created. CUREs face obvious challenges because they operate at a larger scale than the traditional apprentice-based model for undergraduate research, creating resource issues for experimental research that requires equipment, laboratory space, and staff oversight. To help address these hurdles, one university has created a professional development program that provides training, collegial mentoring, and financial support to interested faculty. This paper provides an …
