Diversity In Engineering Technology Students, Eliabeth Dell, Anne M. Lucietto, Elaine Cooney, Lisa Russell, Emily Schott

School of Engineering Education Faculty Publications

In the US, there are two academic pathways to a career in engineering: Engineering and Engineering Technology (ET). Engineering Technology attracts more African American and Latin American students than traditional engineering programs. Nationally, African American students are more than twice as likely to enroll in an ET program versus Engineering. We suspect it may be due to traditional Engineering programs’ requirement of higher levels of math and science classes, often lacking in under-privileged or underserved urban or rural high schools. Recently published research by the New York Equity Coalition supports this supposition. Understanding the reasons for the higher representation of …

General Aviation Hypoxia And Reporting Statistics, Timothy Holt, Jacqueline Luedtke, Jennah Perry, Michelle Hight, Claire Schindler, Pamela Ward

Journal of Aviation Technology and Engineering

Hypoxia is defined as a lack of oxygen throughout the body, which can be caused by several factors at any altitude. General aviation (GA) pilots may argue that most GA aircraft cannot attain the required altitudes where one might be more affected by hypoxia, but it is exactly that attitude that may makes pilots more susceptible to hypoxia. The impact of this hazardous attitude is even more apparent if one considers that out of the 590,038 certificated pilots in the USA, a little over 30% of them are GA pilots (FAA, 2015). The problem is that unlike airline pilots or …

Refining An Instrument And Studying Elementary Teachers’ Understanding Of The Scope Of Engineering, Jacob Pleasants, Joanne K. Olson

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

To effectively incorporate engineering into their instruction, K–12 teachers need sufficient knowledge of the engineering discipline. An important component of teachers’ engineering knowledge is their understanding of the nature of engineering: what engineers do, the epistemological underpinnings of engineering, and the relationships between engineering and other fields of study. In this study, we present a quantitative tool that was developed to assess teachers’ knowledge of a particular nature of engineering dimension: the scope of engineering, which describes the demarcation between engineering and non-engineering. This tool was used to assess the knowledge of teachers and engineering graduate students, before and after …

Incidence Of An Astronaut Not Sealing The Pressure Garment Visor On Reentry, Cameron M. Smith, Trent Tresch

Journal of Human Performance in Extreme Environments

Audiovisual records of a Project Mercury pilot’s activities during an orbital flight indicate that his visor was left open during reentry and descent to the sea surface, phases of flight during which cabin pressure loss was to be mitigated by suit pressurization; however, the suit could not have been pressurized with the visor open. Thus, for a presently unknown reason, a critical safety step—sealing the visor and making a pressure suit integrity test before reentry—was overlooked in this flight. Later, Space Shuttle flights were carried out with visors unsealed for much of the launch and landing phases, with the false …
