   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. Work in Progress: Development of UAS Module in Laboratory Class for a Senior Engineering Core Course.

   Ahad, M. T. ; Siddique, Z. ; Sun, W. ; Gao, J. ( June 2022 , 2022 ASEE Annual Conference & Exposition)

   Designing a senior-level course that involves problem-based learning, including project completion task, is laborious and challenging. A well-designed project motivates the students to be self-learners and prepares them for future industrial or academic endeavors. The COVID-19 pandemic brought many challenges when instructions were forced to move either online or to a remote teaching/learning environment. Due to this rapid transition, delivery modes in teaching and learning modalities faced disruption making course design more difficult. The senior level Flight Controls course AME - 4513 is designed with Unmanned Aerial Systems (UAS) related projects for the students to have a better understanding of UAS usage on various applications in support of Advanced Technological Education (ATE) program. The purpose of this paper is to present the UAS lab modules in a junior level robotics lab, AME - 4802, which preceded the Flight Controls course in the school of Aerospace and Mechanical Engineering at the University of Oklahoma. Successfully completing the course project requires independent research and involves numerical simulations of UAS. The Robotics Lab course focuses on hands-on projects of robotic systems with an emphasis on semi-autonomous mobile robots, including an UAS introduction module. - The UAS module in the Robotics Lab class is introduced in Spring 2020. Therefore, most of the students enrolled in the Spring 2020 Robotics Lab course have introductory knowledge about the UAS system when taking the Fall 2020 Flight Control course. In addition, Spring 2020 Robotics Lab was affected due to COVID-19. - The UAS module was not introduced in 2019 Spring Robotics lab. Thus, the students enrolled in Fall 2019 Flight Controls course did not have prior knowledge on the UAS system. - We thus present the implementation of UAS module in a junior level robotics lab which preceded the senior level Flight Controls course in following Fall semester, when the same instructor taught the course.

4. Experiences during the implementation of two different project-based learning assignments in a fluid mechanics course.

   Ayala, O. ( August 2022 , Zone 1 Conference of the American Society for Engineering Education)

   There is growing evidence of the effectiveness of project-based learning (PBL) in preparing students to solve complex problems. In PBL implementations in engineering, students are treated as professional engineers facing projects centered around real-world problems, including the complexity and uncertainty that influence such problems. Not only does this help students to analyze and solve an authentic real-world task, promoting critical thinking, but also students learn from each other, learning valuable communication and teamwork skills. Faculty play an important part by assuming non-conventional roles (e.g., client, senior professional engineer, consultant) to help students throughout this instructional and learning approach. Typically in PBLs, students work on projects over extended periods of time that culminate in realistic products or presentations. In order to be successful, students need to learn how to frame a problem, identify stakeholders and their requirements, design and select concepts, test them, and so on. Two different implementations of PBL projects in a fluid mechanics course are presented in this paper. This required, junior-level course has been taught since 2014 by the same instructor. The first PBL project presented is a complete design of pumped pipeline systems for a hypothetical plant. In the second project, engineering students partnered with pre-service teachers to design and teach an elementary school lesson on fluid mechanics concepts. With the PBL implementations, it is expected that students: 1) engage in a deeper learning process where concepts can be reemphasized, and students can realize applicability; 2) develop and practice teamwork skills; 3) learn and practice how to communicate effectively to peers and to those from other fields; and 4) increase their confidence working on open-ended situations and problems. The goal of this paper is to present the experiences of the authors with both PBL implementations. It explains how the projects were scaffolded through the entire semester, including how the sequence of course content was modified, how team dynamics were monitored, the faculty roles, and the end products and presentations. Students' experiences are also presented. To evaluate and compare students’ learning and satisfaction with the team experience between the two PBL implementations, a shortened version of the NCEES FE exam and the Comprehensive Assessment of Team Member Effectiveness (CATME) survey were utilized. Students completed the FE exam during the first week and then again during the last week of the semester in order to assess students’ growth in fluid mechanics knowledge. The CATME survey was completed mid-semester to help faculty identify and address problems within team dynamics, and at the end of the semester to evaluate individual students’ teamwork performance. The results showed that no major differences were observed in terms of the learned fluid mechanics content, however, the data showed interesting preliminary observations regarding teamwork satisfaction. Through reflective assignments (e.g., short answer reflections, focus groups), student perceptions of the PBL implementations are discussed in the paper. Finally, some of the challenges and lessons learned from implementing both projects multiple times, as well as access to some of the PBL course materials and assignments will be provided.

5. Introducing Innovation to First-Year STEM Students through an Intercession Course

   https://doi.org/10.18260/1-2-1153-38332  

   Schubert, Karl D. ; Massey, Leslie B. ; Gattis, Carol S. ( November 2021 , 2021 ASEE Midwest Section Conference Proceedings)

   Innovation training is considered critical for the future of our country, yet despite the important role, opportunities for students to develop innovation skills are limited. For STEM students, training in innovation principles and processes are frequently extra curricular pursuits, such as unpaid internships with start up organizations, shadowing innovation professionals, or obtaining an additional business degree or minor covering innovation principles. The National Science Foundation has funded the authors with a Science, Technology, Engineering and Mathematics (S STEM) grant to provide scholarships combined with research on best practices for recruitment, retention, and development of innovation skills for a diverse group of low income undergraduate students. Students in the program come from STEM disciplines in engineering and the physical sciences however, business students are also integrated into innovation courses although they are not funded by the S STEM grant Design, development, and implementation of the grant funded program’s first innovation related course, a 2 week fall intercession course will be presented Th is first year course is designed to provide the students with an introduction to innovation, develop and nurture the students’ innovation mindset and skills, and also help the students’ successful transition to college. The first-year two-week intercession course was designed and developed with two credit hours focusing on content related to innovation and one credit hour focusing on student success topics. The significant academic course components included: 1) interactive active-learning modules related to innovation processes, identifying where good ideas come from, working in teams, leadership, project management, and communication and presentation skills; 2) team innovation projects, one topic-assigned, applying skills learned in the content modules to develop innovation and team collaboration skills; and 3) integration of business students with STEM students which together gives viewpoints and experiences on product and customer needs. It is important to our nation’s health and safety to instill innovation in our students. In addition, today’s students are interested in innovation and in learning how to apply innovation techniques in their professional and personal lives. The course was designed for teams of four STEM students to one business student which provides a balanced input needed for this type of project taking into account the skillset of the technically oriented STEM students and the marketing-oriented business students, as well as personality types. This ensures that all voices are heard, and topical areas are addressed. There was no problem in getting faculty interest in developing the course, and the collaboration between retention professionals and faculty went well. After the course, an iterative improvement retrospective will be performed on the program as implemented to this point to inform improvements for next year’s cohort. This material is based upon work supported by the National Science Foundation under Grant No. 2030297. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.
