This project examines the contributions of environmental effects and role models to the overall sense of belonging and interest in science, technology, engineering, and mathematics (STEM) fields among women. Eleven female engineers, ranging from college freshmen, seniors, and industry members, were interviewed for their perspectives on how their childhoods, female engineers in media, and STEM outreach affiliations affected their career decisions to pursue engineering. Additionally, a student survey was sent to the general Arizona State University population to gauge interest in different engineering challenges. Major, gender, and first-generation status emerged as affecting factors for high interest in certain engineering challenges. As denoted by the survey, male students showed more interest in "Joy of Living" related challenges, while females were more interested in "Health" and "Sustainability" related challenges. First-generation students showed more neutral attitudes than continuing-generation towards most of the engineering challenges. Interview vignettes and survey results were analyzed to identify implications for K-12 outreach and education efforts.

The purpose of this study was to utilize quantitative results gained through surveys to determine the effect of hands-on engineering activities and a poster study on improving understanding and awareness of engineering disciplines in high school students. There was a focus on increasing participation of women and minorities in engineering to improve diversity, and this study utilized biomedical engineering as a means of achieving these goals. The analysis of this thesis focused on the results of the pre-assessment and post-assessment taken by a group of high school students before and after a program using presentations in combination with engineering activities tackling real-world problems. These assessments objectively ranked both the awareness and interest level in various engineering activities across a number of disciplines. The results were analyzed using percentages of the engineering statements that the students recognized as engineering and were interested in, as well as using t-tests. Statistical significance was found for the percentage of statements that the students expressed the highest interest level in between the initial and final survey. The other factors analyzed did not produce statistical significance, but the increase in interest level does meet one of the primary goals of the project. Since the percentages of all the positive factors did increase between the pre- and post- assessment, the study can be considered a success overall; more data is simply needed to indicate significance in these other factors. Future studies will focus on implementing this program as an after-school activity that can be led by members of the engineering community at ASU.

Engineers have a strong influence on everyday lives, ranging from electronics and trains to chemicals and organs [1]. However, in the United States, there is a large knowledge gap in the roles of engineers, especially in K-12 students [2] [3]. The National Academy of Engineering (NAE) recognizes the current problems in engineering, such as the dominance of white males in the field and the amount of education needed to become a successful engineer [4]. Therefore, the NAE encourages that the current engineering community begin to expose the younger generations to the real foundation of engineering: problem-solving [4]. The objective of this thesis is to minimize the knowledge gap by assessing the current perception of engineering amongst middle school and high school students and improving it through engaging and interactive presentations and activities that build upon the students’ problem-solving abilities.

The project was aimed towards middle school and high school students, as this is the estimated level where they learn biology and chemistry—key subject material in biomedical engineering. The high school students were given presentations and activities related to biomedical engineering. Additionally, within classrooms, posters were presented to middle school students. The content of the posters were students of the biomedical engineering program at ASU, coming from different ethnic backgrounds to try and evoke within the middle school students a sense of their own identity as a biomedical engineer. To evaluate the impact these materials had on the students, a survey was distributed before the students’ exposure to the materials and after that assesses the students’ understanding of engineering at two different time points. A statistical analysis was conducted with Microsoft Excel to assess the influence of the activity and/or presentation on the students’ understanding of engineering.

Description
In the United States, there is a national agenda to increase the number of qualified science, technology, engineering, and maths (STEM) professionals and a movement to promote science literacy among the general public.

In the United States, there is a national agenda to increase the number of qualified science, technology, engineering, and maths (STEM) professionals and a movement to promote science literacy among the general public. This project explores the association between formal human evolutionary biology education (HEB) and high school science class enrollment, academic achievement, interest in a STEM degree program, motivation to pursue a STEM career, and socioscientific decision–making for a sample of students enrolled full–time at Arizona State University. Given a lack of a priori knowledge of these relationships, the Grounded Theory Method was used and was the foundation for a mixed–methods analysis involving qualitative and quantitative data from one–on–one interviews, focus groups, questionnaires, and an online survey. Theory development and hypothesis generation were based on data from 44 students. The survey instrument, developed to test the hypotheses, was completed by 486 undergraduates, age 18–22, who graduated from U.S. public high schools. The results showed that higher exposure to HEB was correlated with greater high school science class enrollment, particularly for advanced biological science classes, and that, for some students, HEB exposure may have influenced their enrollment, because the students found the content interesting and relevant. The results also suggested that students with higher K–12 HEB exposure felt more prepared for undergraduate science coursework. There was a positive correlation between HEB exposure and interest in a STEM degree and an indirect relationship between higher HEB exposure and motivation to pursue a STEM career. Regarding a number of socioscientific issues, including but not limited to climate change, homosexuality, and stem cell research, students' behaviors and decision–making more closely reflected a scientific viewpoint—or less–closely aligned to a religion–based perspective—when students had greater HEB exposure, but this was sometimes contingent on students' lifetime exposure to religious doctrine and acceptance of general evolution or human evolution. This study has implications for K–12 and higher education and justifies a paradigm shift in evolution education research, such that more emphasis is placed on students' interests, perceived preparation for continued learning, professional goals and potential contributions to society rather than just their knowledge and acceptance.
