Dissertations and Theses
Currently, STEM (science, technology, engineering, and mathematics) is a popular buzz word in P -12 education as it represents a means to advance American competitiveness in the global economy. Proponents of the engineering component of STEM advocate additional benefits in teaching engineering, such as its capacity to engage students in collaboration, and to apply critical thinking, systems thinking, negotiation, and communication skills to solve real-life contextual problems. Establishing a strong foundation of engineering knowledge at a young age will provide students with internal motivation as it taps into their curiosity toward how things work, and it also prepares them for …
Project Nano: Will Allowing High School Students To Use Research Grade Scanning Electron Microscopes Increase Their Interest In Science?, Leslie Teneyck Smith
Project Nano: Will Allowing High School Students To Use Research Grade Scanning Electron Microscopes Increase Their Interest In Science?, Leslie Teneyck Smith
Dissertations and Theses
In this study, one AP Biology curriculum unit and one general Biology curriculum unit that included tabletop Scanning Electron Microscope (SEM) technology provided by Project NANO, a grant-funded, collaborative initiative designed to integrate cutting-edge nanotechnology into high school classrooms were implemented at a public high school in rural Oregon. Nine students participated in the AP unit and 52 students participated in the general Biology unit. Each student completed an opinion-based pre and post survey to determine if using the SEM as a part of the curriculum unit had an impact on his or her interest in science or in nanoscience. …

A Numerical Solution For The Ultimate Strength Of Tubular Beam-Columns, Arnold L. Wagner
Dissertations and Theses
To provide a basis for the development of interaction curves for tubular beam-columns of annular cross section, a general purpose beam-column computer program is developed, and used to determine ultimate load capacities. The paper presents the analytical model and the computer method. The analytical results are compared with published test data as well as experimental data obtained as part of this project.
