An Investigation Of The Impact Gender-Specific Course Grouping Has On Female Middle-School Students' Concept Of And Interests Toward Technology And Engineering, Thomas Broderick Walsh

Theses and Dissertations

Attempts to improve retention, interest, and enrollment of females in Technology & Engineering Education courses have included a variety of approaches including female-only classes. However, the implications of such courses have not been thoroughly investigated. Therefore, an investigation of female-only classes was undertaken; the findings revealed that the overall enrollment of females went up in the course and in subsequent classes, these students maintained their interests and attitudes towards Technology and Engineering, their perceptions of an engineer's gender changed from that of mostly male to mostly female, and their concepts of what an engineer does changed from mostly building or …

Influencing Perceptions Of Stem Through The Best Stem Books List, Scott Bartholomew, Alexia Seymour

Faculty Publications

One day, while discussing engineering and science as potential career options with a female student, we opened a search engine and typed in “engineer” and “scientist.” However, on the first pages of image results, only one female appeared for engineering and only a few females appeared for “scientist” (see Figure 1). This disparity was disturbing—if this student never saw another person like her filling careers in STEM fields, would she ever “picture herself” in those fields?

Measuring Up: Engineering Stronger And Faster Cardiomyocytes, Kaitlyn Mcentire, Dr. Alonzo Cook

Journal of Undergraduate Research

If a heartbeat connotes life, then cardiomyocytes are the life givers. When heart disease results in cardiomyocyte death, however, these life-giving, beating cells are unable to reproduce, and portions of the heart irreversibly die. Despite modern technology and developments in heart disease treatment and prevention, heart disease remains the number one cause of death in America. With an inability to meet an ever-increasing demand for heart transplants, any potential alternative must be pursued.

Engaging Children In Engineering Design Through The World Of Quadcopters, Greg J. Strimel, Scott R. Bartholomew, Eunhye Kim

Faculty Publications

The interest in engineering education for K-12 students has been rising (Carr, Bennett IV, & Strobel, 2012; Strimel, Grubbs, & Wells, 2016), and the importance of engineering education is discussed as early as the elementary school level (Hegedus, 2014). Petroski (2003) claims that children are ready to learn engineering because their play activities are similar to engineering and design activities, such as making, moving, and rearranging things. Studies have examined how elementary school students perceive engineering or engineers (Cunningham, Lachapelle, & Lindgren-Streicher 2005) and found that elementary-aged students associated engineering with repairing, installing, driving, constructing, and improving machines and devices. …

An Investigation Of The Impact A Rov Competition Curriculum Has On Student Interest In Stem, Specifically Technology And Engineering, Daniel Gordon Bates

Student Works

This research investigates the impact a Remotely Operated Vehicle (ROV) program has on student interest in, and perception of, technology and engineering (sTEm). ROV programs embed areas of science, technology, engineering and math (STEM) into their curriculum; however, emphasis for this study is placed on interest and perception of the "T" and "E" of STEM. Although there are many articles detailing the benefits of ROV programs, there is little empirical data documenting the impact on student interest and perception of sTEm.
