These efforts led to creation of short instructional videos that students can watch before undertaking their …

"But I'M Not An Engineer"...Collaboration Between A Librarian And An Upper Division Project-Based Engineering Program, Heidi J. Southworth, Rebecca Bates, Robert Sleezer

Library Services Publications

Since 2013, a librarian at Minnesota State University, Mankato has collaborated with faculty and students in an upper division project-based engineering program. While having several years of experience in university libraries plus advanced degrees in history, the librarian had a limited background in science, engineering, and technology, and lacked a formal engineering degree. At first glance, this match may appear to be a recipe for failure. Indeed, in those first few years, the librarian’s angst about the missing engineering degree caused many sleepless nights of worry and concern. However, there came a time when the words “but I am not …

The subject areas of science, engineering, and technology are fields in which many of the collaborations occur, and many of the partnerships are often initiated and led by a faculty and a member of industry. Yet, it remains unclear how academia and industry achieve successful partnerships when the goals, language, culture, and organizational structures significantly differ from one organization to another. This study examined whether partnerships among engineering faculty …

Student Responses To Active Learning Strategies: A Comparison Between Project-Based And Traditional Engineering Programs, Elizabeth Pluskwik, Yuezhou Wang

Integrated Engineering Department Publications

Prior research has shown that active learning strategies in engineering education improve student learning, motivation, and retention in STEM disciplines. Yet, instructors are often hesitant to use active learning and other non-lecture strategies due to challenges from students who are resistant to engaging in these methods. Prior research has suggested strategies that can be used to mitigate student resistance to active learning, yet many faculty members have not yet implemented active learning into their engineering education courses. The global demand for entrepreneurially-minded engineers and the rapid growth of engineering programs embracing this mindset increases the need for actionable resources and …

Engineering Students’ Perceptions Of Belongingness In Civil Engineering, Lisa Benson, Candice Bolding, Jennifer Harper Ogle, Catherine Mcgough Spence, Joseph Murphy, Rachel Lanning

Integrated Engineering Department Publications

Prior research shows that engineering students with low feelings of belongingness tend to switch to non-technical majors. With the understanding that aspects of student motivation, identity, and personality, as well as their academic performance, affect their sense of community in engineering, this study seeks to assess these student attributes over time. The context for this study is a single civil engineering program that is undergoing both curricular and cultural changes as part of an NSF-funded project. The data and findings presented here are part of a larger study of how student attitudes and beliefs change during their experiences in a …

Work In Progress - Peer Directed Learning In A Project Based Model, Andrew Mcnally

Journal of Undergraduate Research at Minnesota State University, Mankato

Iron Range Engineering is a new, unique, undergraduate program using problem-based learning. One guiding principle is student responsibility for learning. In order to facilitate learning, faculty and students alike have come up with several learning methods. Learning modes may include self-directed learning, peer-directed learning, one-on-one faculty directed learning, or industry mentored learning. Peer directed learning often manifests in the form of learning groups (a group of students learning similar competencies), led by either a faculty member or a student who has previously excelled in that competency and has taken an interest in pursuing advanced credit. Recently, Iron Range Engineering has …
