   This NSF IUSE project is on the Exploration and Design Tier and the Engaged Student Learning Track. It is aimed at better preparing the country’s professional workforce in the renaissance of U.S. skilled manufacturing by creating new personnel proficient in additive manufacturing (AM). AM is mainstream; it has the potential to bring jobs back to the U.S. and add to the nation’s global competitiveness. AM is the process of joining materials to make objects from 3D data in a layer upon layer fashion. The objectives are to develop, assess, revise, and disseminate an upper division course and laboratory, “Additive Manufacturing,” and to advance undergraduate and K-12 student research and creative inquiry activities as well as faculty expertise at three diverse participating universities: Texas Tech, California State-Northridge, and Kansas State. This research/pedagogical team contains a mechanical engineering professor at each university to develop and teach the course, as well as a sociologist trained in K-12 outreach, course assessment, and human subjects research to accurately determine the effects on K-12 and undergraduate students. The proposed course will cover extrusion-based, liquid-based, and powder-based AM processes. For each technology, fundamentals, applications, and advances will be discussed. Students will learn solutions to AM of polymers, metals, and ceramics. Two lab projects will be built to provide hands-on experiences on a variety of state-of-the-art 3D printers. To stimulate innovation, students will design, fabricate, and measure test parts, and will perform experiments to explore process limits and tackle real world problems. They will also engage K-12 students through video demonstrations and mentorship, thus developing presentation skills. Through the project, different pedagogical techniques and assessment tools will be utilized to assess and improve engineering education at both the undergraduate and K-12 levels through varied techniques: i) undergraduate module lesson plans that are scalable to K-12 levels, ii) short informational video lessons created by undergraduates for K-12 students with accompanying in-person mentorship activities at local high schools and MakerSpaces, iii) pre- and post-test assessments of undergraduates’ and K-12 participating students’ AM knowledge, skills, and perceptions of self-efficacy, and iv) focus groups to learn about student concerns/learning challenges. We will also track students institutionally and into their early careers to learn about their use of AM technology professionally.

3. Creating and Assessing an Upper Division Additive Manufacturing Course and Laboratory to Enhance Undergraduate Research and Innovation

   Maloney, P ; Cong, W ; Zhang, M ; Li, B. ( June 2019 , Proceedings of the American Society of Engineering Education)

   Additive manufacturing (AM) is prevalent in academic, industrial, and layperson use for the design and creation of objects via joining materials together in a layer upon layer fashion. However, few universities have an undergraduate course dedicated to it. Thus, using NSF IUSE support [grant number redacted for review] from the Exploration and Design Tier of the Engaged Student Learning Track, this project has created and implemented such a course at three large universities: Texas Tech (a Carnegie high research productivity and Hispanic Serving Institution), Kansas State (a Carnegie high research productivity and land grant university) and California State, Northridge (the largest of all the California State campuses and highly ranked in serving underprivileged students). Our research team includes engineering professors and a sociologist trained in assessment and K-12 outreach to determine the effects of the course on the undergraduate and high school students. We are currently in year two of the three years of NSF support.

4. The Cumulative Effects of an NSF-Funded Additive Manufacturing Course at Three Large State Universities and Their Surrounding Communities

   Maloney, Patricia. ; Cong, Weilong. ; Zhang, Meng. ; Li, Bingbing. ( August 2022 , Proceedings ASEE annual conference)

   This paper is the culmination of four years of an NSF-funded project implementing and assessing an undergraduate additive manufacturing course at three large state universities: Texas Tech University, Kansas State University, and California State University – Northridge. The research questions addressed are: (1) What are the changes in skill and knowledge concerning additive manufacturing experienced by undergraduate students? (2) What is the effect of this course on attitudes towards engineering and self-efficacy in engineering for enrolled undergraduate students? The sample consists of four years of data from the undergraduate students enrolled in the course at all three universities (combined N = 196). Our method for data collection was matched-pair surveys that contained both (i) an assessment for content knowledge and (ii) an attitudinal assessment previously validated in published research for data collection about attitudes towards engineering. Matched-pair surveys means that we collected data from Student X at Time 1 (before being taught) and then again from at Time 2 (after being taught) and are able to directly compare any change in content knowledge or attitude within the same person. We also collected demographic information to be able to see whether changes in, for example, women differed from those in men. All undergraduates experienced statistically significant increases in content knowledge and additive manufacturing skills. In an intriguing finding, female students outperformed male students, which fits with the research that indicates that engineering courses which emphasize pragmatic and real-world applications, as well as those that use group work, will disproportionately help underserved engineering populations like women and people of color succeed. Fitting with the above finding, undergraduates noted that they perceived that they had increased in teamwork, communication, and computer programming skills. These gains were particularly high in female students and students of color.

5. Assessing Awareness and Competency of Engineering Freshmen on Ethical and Responsible Research and Practices

   Johnson, M.D. ( January 2023 , American Society of Engineering Education Annual Conference)

   This paper presents the progress made in the first year of a five-year NSF ER2 (Ethical and Responsible Research)-funded project on ethical and responsible research and practices in science and engineering undertaken at a large public university in the southwestern United States. The objective of this research is to improve instructor training, interventions, and student outcomes in high schools and universities to improve awareness and commitment to ethical practices in STEM coursework. The paper will describe the progress made in several components of the grant: i) Preliminary analysis of measures of ethical knowledge, reasoning skills, attitudes, and practices of several hundred undergraduate freshmen and seniors, correlated with demographic data, based on data captured in the first year of the grant; ii) Progress made in the development of the concept of “ethical self-efficacy” and an instrument to measure it for freshmen and senior engineering students, and in assessing how it relates to ethical competency and student background; iii) Implications of these analyses in the construction of a three-week professional development program that guides high school STEM teachers through the development of learning modules on ethical issues related to their courses; iv) The assessment of the undergraduate engineering curriculum in two majors to determine appropriate courses for ethics interventions to help students understand how technical activities fit within broader social, economic, and environmental contexts; the construction of these interventions; and the development of measures to track their success; and, v) Initial steps toward measuring impact of other experiences (e.g., undergraduate research, internships, service learning) and courses (e.g., humanities, social science, and business courses) on development of ethical practices, on assessments taken in senior engineering capstone courses.
