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.

The Internet of Things (IoT) is term used to refer to the billions of Internet connected, embedded devices that communicate with one another with the purpose of sharing data or performing actions. One of the core usages of the proverbial network is the ability for its devices and services to interact with one another to automate daily tasks and routines. For example, IoT devices are often used to automate tasks within the household, such as turning the lights on/off or starting the coffee pot. However, designing a modular system to create and schedule these routines is a difficult task.

Current IoT integration utilities attempt to help simplify this task, but most fail to satisfy one of the requirements many users want in such a system ‒ simplified integration with third party devices. This project seeks to solve this issue through the creation of an easily extendable, modular integrating utility. It is open-source and does not require the use of a cloud-based server, with users hosting the server themselves. With a server and data controller implemented in pure Python and a library for embedded ESP8266 microcontroller-powered devices, the solution seeks to satisfy both casual users as well as those interested in developing their own integrations.

Engineering is a heavily male-dominated field and females are significantly less likely to choose an engineering-related major or career path. At the age of six years old, females start believing that their male peers are smarter than them, leading them to pursue less ambitious careers. The children's book Lyla B. An Engineering Legacy was created to encourage more young girls to discover their own potential and pursue engineering as a career. To explore the efficacy of the book on its target consumers, a pilot study was performed with first and second grade children. The participants' engineering knowledge; fixed and failure mindset beliefs; STEM (Science, Technology, Engineering, and Math) interest, competency, and career aspirations; and stereotype beliefs were evaluated before and after being read the book to determine if the story has a positive impact on children. Additionally, the satisfaction of the participants towards both the book and main character were analyzed quantitatively and qualitatively. Overall, the results of the study suggest that the book has a positive impact on the interest and competency of STEM fields and the stereotype beliefs that the children had towards engineers. The study also suggests that the book decreases fixed and failure mindsets and that the participants were satisfied with the overall concept of the book and main character, Lyla.

Parents in STEM careers are more apt to guide their kids towards STEM careers (Sherburne-Michigan, 2017). There are STEM programs and classes for students who are interested in related fields, but the conundrum is that students need to be interested in order to choose to participate. The goal of this creative project was to introduce engineering concepts in a high school class to reveal and investigate the ways in which engineering concepts can be successfully introduced to a larger student populace to increase interest in engineering programs, courses, and degrees. A lesson plan and corresponding materials - including circuit kits and a simulated ball launching station with graphical display - were made to accomplish this goal. Throughout the lesson students were asked to (1) use given materials to accomplish a goal, (2) predict outcomes based on conceptual understanding and mathematical calculations, (3) test predictions, (4) record data, and (5) analyze data to generate results. The students first created a simple circuit to understand the circuit components and learn general electrical engineering concepts. A simple light dimmer circuit let students demonstrate understanding of electrical concepts (e.g., voltage, current resistance) before using the circuit to a simulated motor in order to launch a ball. The students were then asked to predict the time and height of a ball launched with various settings of their control circuit. The students were able to test their theories with the simulated launcher test set up shown in Figure 25 and collect data to create a parabolic height versus time graph. Based on the measured graph, the students were able to record their results and compare calculated values to real-world measured values. The results of the study suggest ways to introduce students to engineering while developing hands-on concept modeling of projectile motion and circuit design in math classrooms. Additionally, this lesson identifies a rich topic for teachers and STEM education researchers to explore lesson plans with interdisciplinary connections to engineering. This report will include the inspiration for the product, related work, iterative design process, and the final design. This information will be followed by user feedback, a project reflection, and lessons learned. The report will conclude with a summary and a discussion of future work.

Cooperative education has a long-standing tradition within engineering education. As part of the experiential education field, it carries many success stories. Several universities offer a robust cooperative education track. In recent years, Arizona State University has made the decision to formalize a cooperative education program. Arizona State University, like many other institutions, has long since provided career support and promoted internships as an excellent work experience option before graduation. The decision to formalize a cooperative education program speaks to a need for a more rigorous path to work experience for engineering students. This paper is an investigation into the barriers and enablers behind a young cooperative education program. These results indicate that while students do benefit from the program, growth of the program may be tied to creating a meaningful distinction between cooperative education and other learning opportunities.

There is an interest in citizen scientist networks such as CoCoRaHS to develop an air temperature sensor with a solar shield that is both extremely low cost and user friendly for use in widespread data collection in order to analyze urban microclimates. This paper outlines work done to develop a low cost micrometeorology instrument to fulfill the design requirements set by CoCoRaHS. While the first two revisions of this technology had significant changes in development, a third revision was created as a proof of concept that low cost temperature sensors could be used in an array to accurately measure air temperature without solar radiation interference. Another technology, described as revision four, called the iButton was also evaluated and displayed promising ability to log temperatures, but costs too much for the ultra-low cost design goal. Additionally, work was done to design a radiation shield that will be prototyped and tested alongside commercial radiation shields. This controlled experiment will also include further evaluation of the iButton and the next revision of a custom microclimate temperature sensing unit to determine the best option for widespread field testing.

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.

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.

The National Research Council developed and published the Framework for K-12 Science Education, a new set of concepts that many states were planning on adopting. Part of this new endeavor included a set of science and engineering crosscutting concepts to be incorporated into science materials and activities, a first in science standards history. With the recent development of the Framework came the arduous task of evaluating current lessons for alignment with the new crosscutting concepts. This study took on that task in a small, yet important area of available lessons on the internet. Lessons, to be used by K-12 educators and students, were produced by different organizations and research efforts. This study focused specifically on Earth science lessons as they related to earthquakes. To answer the question as to the extent current and available lessons met the new crosscutting concepts; an evaluation rubric was developed and used to examine teacher and student lessons. Lessons were evaluated on evidence of the science, engineering and application of the engineering for each of the seven crosscutting concepts in the Framework. Each lesson was also evaluated for grade level appropriateness to determine if the lesson was suitable for the intended grade level(s) designated by the lesson. The study demonstrated that the majority of lesson items contained science applications of the crosscutting concepts. However, few contained evidence of engineering applications of the crosscutting concepts. Not only was there lack of evidence for engineering examples of the crosscutting concepts, but a lack of application engineering concepts as well. To evaluate application of the engineering concepts, the activities were examined for characteristics of the engineering design process. Results indicated that student activities were limited in both the nature of the activity and the quantity of lessons that contained activities. The majority of lessons were found to be grade appropriate. This study demonstrated the need to redesign current lessons to incorporate more engineering-specific examples from the crosscutting concepts. Furthermore, it provided evidence the current model of material development was out dated and should be revised to include engineering concepts to meet the needs of the new science standards.
