Recent advancements in Additive Manufacturing (AM)/3D Printing have influenced a change in object design and production. This has attracted many production industries to adopt the AM technique, resulting in a proportionate need for a workforce skilled in AM. In tandem, AM education has been introduced in schools to develop the AM-skilled…

This three-manuscript dissertation in practice used improvement science as the methodological approach of disciplined inquiry into a problem of practice--the discrepancy of male and female participation in engineering design-based (EDB) courses and clubs in Starr School District. Manuscript 1 centered around diagnosing the problem and delved into…

The purpose of this study was to explore the impact of design thinking instruction on the creativity of preservice teachers. Preservice teachers took part in a two-week unit on 3D printing as a part of their regular instruction in an educational technology course. The experimental group was introduced to design thinking instruction as a framework…

This dissertation measured the impact of the integration of STEM (Science, Technology, Engineering, and Math) and historical inquiry on 10 and 11 year old 5th grade charter school students. By using Q methodology, a mixed methodology research tool, this study examined three hypotheses. These include the outcomes of holistic learning, the effect of…

In response to the maker movement, administrators are adding 3D printers, laser cutters, vinyl cutters, and other computer-controlled machinery into school-based makerspaces at a rapid rate. These digital fabrication tools can potentially engage students in hands-on learning across all subject areas. However, adding these extra tools into schools…

Although extensive research has focused on young children's writing and identified the importance of early writing experiences, there is a limited amount of writing occurring in some early childhood classrooms. Furthermore, existing research on teacher supports for emergent writing in preschool classrooms is limited. This study examined how one…

This study focuses on the use of American Invention Kits from the Smithsonian Institute in conjunction with a 3D printer. In conjunction with a large dataset from a study funded by the National Science Foundation (NSF), this innovative research focuses on the effect the digital fabrication curriculum unit has on gifted and talented students'…

Advances in mechanical and electrical engineering and an evolving workforce have prompted education systems in the United States to incorporate technology as both a subject of learning and a pedagogical tool. The rising workforce must be literate in the use, maintenance, and creation of technologies as more labor and service jobs become automated.…

In this dissertation, I explored the lives of 10 children who were diagnosed with a language disorder. The children were enrolled in a therapeutic half-day speech-language preschool classroom for 3- and 4-year-old children within a public-school system in the rural Southeast. The research included a 15-week mini-ethnographic case study utilizing…

While the changing nature of design activity is a topic supported by a range of popular and academic publications, the role that design tools have taken in that change is less well studied. The tools used in the trade, both by industrial designers and mechanical engineers, have undergone a rapid transformation in the last fifty years. The research…

The purpose of this qualitative study was to explore the use of 3-D printed models as an instructional tool in a middle school science classroom for students with visual impairments and compare their use to traditional tactile graphics for aiding conceptual understanding of geoscience concepts. Specifically, this study examined if the students'…

Multibeam interference lithography is investigated as a manufacturing technique for three-dimensional photonic crystal templates. In this research, optimization of the optical setup and the photoresist initiation system leads to a significant improvement of the optical quality of the crystal, as characterized by normal incidence optical…

Electronics that can cover large areas, often referred to as macroelectronics, has received increasing attention over the past decade mainly due to it use in display systems, but increasingly due to certain forms of macroelectronics that can be integrated with thin plastic sheets or elastomeric substrates to yield mechanically flexible and…
