Description
Based on James Marcia's theory, identity development in youth is the degree to which one has explored and committed to a vocation [1], [2]. During the path to an engineering identity, students will experience a crisis, when one's values and choices are examined and reevaluated, and a commitment, when the outcome of the crisis leads the student to commit to becoming an engineer. During the crisis phase, students are offered a multitude of experiences to shape their values and choices to influence commitment to becoming an engineering student. Student's identities in engineering are fostered through mentoring from industry, alumni, and peer coaching [3], [4]; experiences that emphasize awareness of the importance of professional interactions [5]; and experiences that show creativity, collaboration, and communication as crucial components to engineering. Further strategies to increase students' persistence include support in their transition to becoming an engineering student, education about professional engineers and the workplace [6], and engagement in engineering activities beyond the classroom. Though these strategies are applied to all students, there are challenges students face in confronting their current identity and beliefs before they can understand their value to society and achieve personal satisfaction. To understand student's progression in developing their engineering identity, first year engineering students were surveyed at the beginning and end of their first semester. Students were asked to rate their level of agreement with 22 statements about their engineering experience. Data included 840 cases. Items with factor loading less than 0.6 suggesting no sufficient explanation were removed in successive factor analysis to identify the four factors. Factor analysis indicated that 60.69% of the total variance was explained by the successive factors. Survey questions were categorized into three factors: engineering identity as defined by sense of belonging and self-efficacy, doubts about becoming an engineer, and exploring engineering. Statements in exploring engineering indicated student awareness, interest and enjoyment within engineering. Students were asked to think about whether they spent time learning what engineers do and participating in engineering activities. Statements about doubts about engineering to engineering indicated whether students had formed opinions about their engineering experience and had understanding about their environment. Engineering identity required thought in belonging and self-efficacy. Belonging statements called for thought about one's opinion in the importance of being an engineer, the meaning of engineering, an attachment to engineering, and self-identification as an engineer. Statements about self-efficacy required students to contemplate their personal judgement of whether they would be able to succeed and their ability to become an engineer. Effort in engineering indicated student willingness to invest time and effort and their choices and effort in their engineering discipline.

Description
To supplement lectures, various resources are available to students; however, little research has been done to look systematically at which resources studies find most useful and the frequency at which they are used. We have conducted a preliminary study looking at various resources available in an introductory material science course over four semesters using a custom survey called the Student Resource Value Survey (SRVS). More specifically, the SRVS was administered before each test to determine which resources students use to do well on exams. Additionally, over the course of the semester, which resources students used changed. For instance, study resources for exams including the use of homework problems decreased from 81% to 50%, the utilization of teaching assistant for exam studying increased from 25% to 80%, the use of in class Muddiest Points for exam study increased form 28% to 70%, old exams and quizzes only slightly increased for exam study ranging from 78% to 87%, and the use of drop-in tutoring services provided to students at no charge decreased from 25% to 17%. The data suggest that students thought highly of peer interactions by using those resources more than tutoring centers. To date, no research has been completed looking at courses at the department level or a different discipline. To this end, we adapted the SRVS administered in material science to investigate resource use in thirteen biomedical engineering (BME) courses. Here, we assess the following research question: "From a variety of resources, which do biomedical engineering students feel addresses difficult concept areas, prepares them for examinations, and helps in computer-aided design (CAD) and programming the most and with what frequency?" The resources considered include teaching assistants, classroom notes, prior exams, homework problems, Muddiest Points, office hours, tutoring centers, group study, and the course textbook. Results varied across the four topical areas: exam study, difficult concept areas, CAD software, and math-based programming. When preparing for exams and struggling with a learning concept, the most used and useful resources were: 1) homework problems, 2) class notes and 3) group studying. When working on math-based programming (Matlab and Mathcad) as well as computer-aided design, the most used and useful resources were: 1) group studying, 2) engineering tutoring center, and 3) undergraduate teaching assistants. Concerning learning concepts and exams in the BME department, homework problems and class notes were considered some of the highest-ranking resources for both frequency and usefulness. When comparing to the pilot study in MSE, both BME and MSE students tend to highly favor peer mentors and old exams as a means of studying for exams at the end of the semester1. Because the MSE course only considered exams, we cannot make any comparisons to BME data concerning programming and CAD. This analysis has highlighted potential resources that are universally beneficial, such as the use of peer work, i.e. group studying, engineering tutoring center, and teaching assistants; however, we see differences by both discipline and topical area thereby highlighting the need to determine important resources on a class-by-class basis as well.

Description
A concept found that students struggle with in statics and dynamics is free body diagrams. To capture the difficulties students have with this concept, faculty interviews were conducted to determine common errors seen in a classroom setting. The feedback was used to pull questions from a statics concept inventory focused on free body diagrams. Students who have passed statics and dynamics courses in their engineering degree were asked to participate in talk alouds to confirm the faculty input. The talk alouds provided first hand observations of the student thought process when they perform common errors in creating free body diagrams. The results highlighted that students commonly add forces that are not there or fail to only depict the external forces acting on the system in question. A professor describes the occurrence when students insist on adding forces that are not there as phantom forces. To remedy the idea of phantom forces, an intervention was proposed to be implemented into the classroom.

Description
Makers are those who enjoy creating things and learning new skills, as well as interacting within a connected community (Doughtery, 2012). Through the analysis of Makers as part of a larger study (Jordan & Lande, 2013) a researcher had noticed the emergence of leadership traits within the Maker community (Oplinger, Jordan, and Lande, 2015). The National Academy of Engineering has determined that leadership is a key quality for the engineer of the future (Clough, 2004). The Engineering Accreditation Commission has determined several necessary outcomes for engineering students that coincide with leadership roles (Engineering Accreditation Commission, 2012). Proactiveness, confidence, motivation, communication, coaching will be important skills for engineers so that they can effectively lead teams, adjust to change, and synthesize (Ahn, Cox, London, Cekic, and Zhu, 2014). In National Academy of Engineering's The Engineer of 2020 (Clough, 2004) future engineers are expected to be in position to influence "in the making of public policy and in the administration of government and industry." The Maker community offers a broad spectrum of individuals engaged in informal engineering and tinkering activities across multiple pathways (Foster, Wigner, Lande, and Jordan, 2015). This study explores leadership using a theoretical framework of competing values (Quinn, 1988) (Zafft, Adams, and Matkin, 2009) including relating to people, managing processes, leading change, and producing results. The study relies upon artifact elicitation (based on photo elicitation (Harper, 2002)) with 40 of these Makers at four Maker Faires in the United States. The artifact elicitation interviews were conducted at the Maker Faires in front of participants' inventions, where the Makers were asked to describe the invention and the process behind it. Using a theoretical framework of competing values (Quinn, 1988) (Quinn, Faerman, Thompson, and McGrath, 1990) and through parallel inductive-deductive analysis, the emergent themes among our sample of Makers include that they express leadership qualities of (1) innovators \u2014 they utilize different skillsets to develop unique products and solutions; (2) monitors \u2014 they evaluate projects and respond to results; (3) directors \u2014 they set goals and expectations of their projects and processes; and (4) producers \u2014 they are determined and possess a personal drive. From the findings a call to action is made on implementing leadership lessons in the engineering classroom.

Description
Adaptive expertise is a model of learning that posits two dimensions of development: efficiency and innovation. The mindset of an adaptive expert will serve any engineer by drawing upon diverse experiences to develop novel solutions to problems. Their mindset is based in lifelong learning, characterized by applying past experience to current design challenges. Solution design requires a process, and a breadth of experience is among the adaptive expert's greatest tools in identifying the approach to take in an unfamiliar situation. The fluidity and agility of their mind allows them to work effectively throughout their career in technical design, as the situation of an engineer's design work can vary drastically over the course of time. This paper describes a study on an innovative junior-level electrical and robotic systems project course taught at a large southwestern university that encourages students to develop adaptive expertise in the context of real-world design projects. By fabricating prototypes, students learn strategies for troubleshooting and technical design, and iterations of the part demand reflection on previous design thinking. This study seeks to answer the following research questions: (1) How does user-centered design stimulate abstractive design thinking? (2) How does fabrication of prototypes stimulate active design thinking? And (3) How is the classroom culture enabling engineering design in the optimal adaptability corridor? Critical incident interviews were conducted with stakeholders in the course, and a thematic analysis of the transcripts conducted. Results show that this project-based curriculum fosters adaptive expertise by stimulating both abstractive and active design thinking. This provides a framework for practicing adaptive design thinking in classrooms. Disseminating these findings to curriculum designers will encourage more engaging, effective classes that graduate adaptive experts.

Description
The goal of this research study was to empirically study the effects of a project based learning activity. The effectiveness of this study was benchmarked according to two results: the effectiveness in communicating the scope and impact of engineering, and the effectiveness in increasing interest in computer systems engineering (CSE). This research report presents an analysis of the effects of making engineering education socially relevant, interesting and accessible. High school students participated in a learning experience in which they designed flood evacuation systems that could warn a city of incoming floods. Both pre-assessments and post-assessments were implemented to capture students' awareness of engineering tasks and their interest levels in engineering tasks. Data on students' perceptions of specific engineering tasks were analyzed quantitatively through Wilcoxon signed-rank testing and determined that the program had significant positive effects on developing more accurate conceptions of engineering tasks. The results relating to student interest in CSE indicated that there was an increased level of interest in CSE engineering tasks after the program. There was a 14% increase in number of students who found engineering tasks interesting from 64% to 78%. However, as participants self-selected to participate in this learning experience, many students had positive perceptions of engineering tasks prior to engaging in the learning experience. This study was successful and met both of its primary goals of enhancing awareness and interest in engineering in this particular group of high school students.

Description
Flipped classrooms invert the traditional teaching methods and deliver the lecture online outside of the classroom. An increase in technology accessibility is increasing the prevalence of this teaching technique in universities. In this study, we aim to address some of the uncertainties of a flipped classroom by implementing a new lecture format in Transport Phenomena. Transport Phenomena is a junior level biomedical engineering course originally flipped in Spring 2013. Since transitioning to a flipped classroom, students have been required to watch 75-minute lectures outside of class where the instructor covered key concepts and examples using paper and marker on a document camera. In class, students then worked in groups to solve problems with instructor and teaching assistant feedback. Students also completed self-graded homework with the opportunity to earn lost points back by discussing fundamental misconceptions. We are introducing re-formatted mini lectures that contain the same content broken down as well as example problems worked out in a tutorial technique instead of traditional solving method. The purpose of this study is to determine the effectiveness of newly created mini lectures with integrated questions and links in terms of student achievement and attitude [interest, utility, and "cost" (time, effort, and emotion)].

Description
This study sought the lived and told stories of Native American women working in engineering and technology so that their voices may be heard in engineering education scholarship and challenge assumptions surrounding universal understandings of what it means to be a minority woman in science, technology, engineering, and mathematics (STEM). The study was directed by two research questions: (1) What are the lived and told stories of Native women in engineering and technology who are leading initiatives to improve their Native communities and (2) How do Native women’s understandings of their identities influence their work and acts of leadership? The study employed narrative inquiry as the methodological framework and was guided by theoretical frameworks of identities as constructed, multiple, and intersectional (Crenshaw, 1989; Tajfel & Turner, 1979), hybridity, and “third spaces” (Bhabha, 2012). The inquiry was also informed by feminist theories of Native scholars (Green, 1983; Kidwell, 1978) and engineering education (Beddoes & Borrego, 2011; Riley, Pawley, Tucker, & Catalano, 2009). The narrative analysis presented three narratives, based upon interviews, field notes, observations, and documents: (1) the story of a Navajo woman working within a large technical corporation (Jaemie); (2) the story of an Akimel O’odham-Mexican woman working within a tribally-owned technical business (Mia); and (3) the story of a Navajo woman growing her own technical business (Catherine). The narratives revealed a series of impactful transitions that enabled Jaemie, Mia, and Catherine to work and lead in engineering and technology. The transitions revolved around themes of becoming professionals, encountering and overcoming hardship, seeking to connect and contribute to Natives through work, leading change for their Native communities, and advancing their professional selves and their Native communities. Across the transitions, a transformation emerged from cultural navigation to leadership for the creation of new hybrid spaces that represented innovative sites of opportunity for Native communities. The strength of the Native spaces enabled Jaemie, Mia, and Catherine to leverage their identities as Native women within the global context of engineering and technology. The narratives denote the power of story by contributing the depth and richness of lived realities in engineering and technology.

Description
The 21st century will be the site of numerous changes in education systems in response to a rapidly evolving technological environment where existing skill sets and career structures may cease to exist or, at the very least, change dramatically. Likewise, the nature of work will also change to become more automated and more technologically intensive across all sectors, from food service to scientific research. Simply having technical expertise or the ability to process and retain facts will in no way guarantee success in higher education or a satisfying career. Instead, the future will value those educated in a way that encourages collaboration with technology, critical thinking, creativity, clear communication skills, and strong lifelong learning strategies. These changes pose a challenge for higher education’s promise of employability and success post-graduation. Addressing how to prepare students for a technologically uncertain future is challenging. One possible model for education to prepare students for the future of work can be found within the Maker Movement. However, it is not fully understood what parts of this movement are most meaningful to implement in education more broadly, and higher education in particular. Through the qualitative analysis of nearly 160 interviews of adult makers, young makers and young makers’ parents, this dissertation unpacks how makers are learning, what they are learning, and how these qualities are applicable to education goals and the future of work in the 21st century. This research demonstrates that makers are learning valuable skills to prepare them for the future of work in the 21st century. Makers are learning communication skills, technical skills in fabrication and design, and developing lifelong learning strategies that will help prepare them for life in an increasingly technologically integrated future. This work discusses what aspects of the Maker Movement are most important for integration into higher education.

Description
The goal of this research study was to empirically study a poster-based messaging campaign in comparison to that of a project-based learning approach in assessing the effectiveness of these methods in conveying the scope of biomedical engineering to upper elementary school students. For the purpose of this honors thesis, this research paper specifically reflects and analyzes the first stage of this study, the poster-based messaging campaign. 6th grade students received socially relevant messaging of juniors and seniors at ASU achieving their biomedical aspirations, and received information regarding four crucial themes of biomedical engineering via daily presentations and a website. Their learning was tracked over the course of the weeklong immersion program through a pre/post assessment. This data was then analyzed through the Wilcoxon matched pairs test to determine whether the change in biomedical engineering awareness was statistically significant. It was determined that a poster-based messaging campaign indeed increased awareness of socially relevant themes within biomedical engineering, and provided researchers with tangible ways to revise the study before a second round of implementation. The next stage of the study aims to explain biomedical engineering through engaging activities that stimulate making while emphasizing design-aesthetic appeal and engineering habits of mind such as creativity, teamwork, and communication.
