1. Theory to Practice: Professional Development for Culturally Responsive Technician Education

   Pickering, C. ( July 2022 , ASEE Annual Conference proceedings)

   The HSI (Hispanic Serving Institution) ATE (Advanced Technological Education) Hub 2 is a three-year collaborative research project funded by the National Science Foundation (NSF) that continues the partnership between two successful programs and involves a third partner in piloting professional development that draws upon findings from the initial program. The goal of HSI ATE Hub 2 is to improve outcomes for Latinx students in technician education programs through design, development, pilot delivery, and dissemination of a 3-tier professional development (PD) model for culturally responsive technician education at 2-year Hispanic Serving Institutions (HSIs). The project seeks to do this by developing the awareness and ability of faculty to appreciate, engage, and affirm the unique cultural identities of the students in their classes and use this connection to deepen students’ belonging and emerging identities as STEM learners and future STEM technicians. This paper shares the research foundations shaping this approach and the methods by which faculty professional development is being provided to develop this important and sensitive instructional capability in participating faculty. The tiered PD model features a scaffolded series of reflective and activity-oriented modules to incrementally enrich the instructional practices and mindset of HSI STEM educators and strengthen their repertoire of strategies for engaging culturally diverse students. Scaffolding that translates culturally responsive theory to practice spans each of the four distinct topic modules in each tier. Each topic module in a tier then scaffolds to a more advanced topic module in the next tier. Tier 1, Bienvenidos, welcomes HSI STEM educators who recognize the need to better serve their Latinx students, and want guidance for small practical activities to try with their students. Tier 2, Transformation through Action, immerses HSI STEM educators in additional activities that bring culturally responsive practices into their technician training while building capacity to collect evidence about impacts and outcomes for students. Tier 3, Engaging Community, strengthens leadership as HSI STEM educators disseminate results from activities completed in Tiers 1 and 2 at conferences that attract technician educators. Sharing the evidence-based practices and their outcomes contributes to achieving broader impacts in the Advanced Technological Education or ATE Community of NSF grantees. Westchester Community College (WCC), the first 2-year HSI in the State University of New York (SUNY) 64 campus system, is piloting the 3-tier PD model using virtual learning methods mastered through previous NSF ATE work and the COVID-19 context. During the pilot, over 20 WCC technician educators in three cohorts will develop leadership skills and practice culturally responsive methods. The pilot will build capacity within WCC STEM technician programs to better support the diversity of students, industry demand for a diverse workforce, and WCC’s capacity for future development of technician education programs. This first paper in a three part series describes the program goals and objectives, the 3-Tier PD model, and reports initial results for Cohort A’s engagement in the first three modules of Tier 1.

3. Work in Progress: Interactive Introductory Online Modules on Wireless Communications and Radio-frequency Spectrum Sharing

   Dietrich, C. B. ; Polys, N. F. ; Reid, K. ; García Sheridan, J. A. ; Emenonye, D. ; Gomez, X. ; Tolley, J. ; Makin, C. ; Gaeddert, J. ( July 2021 , ASEE Annual Conference proceedings)

   1. Description of the objectives and motivation for the contribution to ECE education The demand for wireless data transmission capacity is increasing rapidly and this growth is expected to continue due to ongoing prevalence of cellular phones and new and emerging bandwidth-intensive applications that encompass high-definition video, unmanned aerial systems (UAS), intelligent transportation systems (ITS) including autonomous vehicles, and others. Meanwhile, vital military and public safety applications also depend on access to the radio frequency spectrum. To meet these demands, the US federal government is beginning to move from the proven but inefficient model of exclusive frequency assignments to a more-efficient, shared-spectrum approach in some bands of the radio frequency spectrum. A STEM workforce that understands the radio frequency spectrum and applications that use the spectrum is needed to further increase spectrum efficiency and cost-effectiveness of wireless systems over the next several decades to meet anticipated and unanticipated increases in wireless data capacity. 2. Relevant background including literature search examples if appropriate CISCO Systems’ annual survey indicates continued strong growth in demand for wireless data capacity. Meanwhile, undergraduate electrical and computer engineering courses in communication systems, electromagnetics, and networks tend to emphasize mathematical and theoretical fundamentals and higher-layer protocols, with less focus on fundamental concepts that are more specific to radio frequency wireless systems, including the physical and media access control layers of wireless communication systems and networks. An efficient way is needed to introduce basic RF system and spectrum concepts to undergraduate engineering students in courses such as those mentioned above who are unable to, or had not planned to take a full course in radio frequency / microwave engineering or wireless systems and networks. We have developed a series of interactive online modules that introduce concepts fundamental to wireless communications, the radio frequency spectrum, and spectrum sharing, and seek to present these concepts in context. The modules include interactive, JavaScript-based simulation exercises intended to reinforce the concepts that are presented in the modules through narrated slide presentations, text, and external links. Additional modules in development will introduce advanced undergraduate and graduate students and STEM professionals to configuration and programming of adaptive frequency-agile radios and spectrum management systems that can operate efficiently in congested radio frequency environments. Simulation exercises developed for the advanced modules allow both manual and automatic control of simulated radio links in timed, game-like simulations, and some exercises will enable students to select from among multiple pre-coded controller strategies and optionally edit the code before running the timed simulation. Additionally, we have developed infrastructure for running remote laboratory experiments that can also be embedded within the online modules, including a web-based user interface, an experiment management framework, and software defined radio (SDR) application software that runs in a wireless testbed initially developed for research. Although these experiments rely on limited hardware resources and introduce additional logistical considerations, they provide additional realism that may further challenge and motivate students. 3. Description of any assessment methods used to evaluate the effectiveness of the contribution, Each set of modules is preceded and followed by a survey. Each individual module is preceded by a quiz and followed by another quiz, with pre- and post-quiz questions drawn from the same pool. The pre-surveys allow students to opt in or out of having their survey and quiz results used anonymously in research. 4. Statement of results. The initial modules have been and are being used by three groups of students: (1) students in an undergraduate Introduction to Communication Systems course; (2) an interdisciplinary group of engineering students, including computer science students, who are participating in related undergraduate research project; and (3) students in a graduate-level communications course that includes both electrical and computer engineers. Analysis of results from the first group of students showed statistically significant increases from pre-quiz to post-quiz for each of four modules on fundamental wireless communication concepts. Results for the other students have not yet been analyzed, but also appear to show substantial pre-quiz to post-quiz increases in mean scores.

4. Engaging Female High School Students in the Frontiers of Computing

   Stein, G. ; Gransbury, I. ; Jean, D. ; Alvarez ; L. ; Hill, M. ; Catete, V. ; Grover, S. ; Barnes, T. ; Broll, B. ; et al ( January 2022 , 2022 ASEE Annual Conference & Exposition)

   Creating pathways that stimulate high school learners’ interest in advanced topics with the goal of building a diverse, gender-balanced, future-ready workforce is crucial. To this end, we present the curriculum of a new, high school computer science course under development called Computer Science Frontiers (CSF). Building on the foundations set by the AP Computer Science Principles course, we seek to dramatically expand access, especially for high school girls, to the most exciting and emerging frontiers of computing, such as distributed computation, the internet of things (IoT), cybersecurity, and machine learning. The modular, open-access, hands-on curriculum provides an engaging introduction to these advanced topics in high school because currently they are accessible only to CS majors in college. It also focuses on other 21st century skills required to productively leverage computational methods and tools in virtually every profession. To address the dire gender disparity in computing, the curriculum was designed to engage female students by focusing on real world application domains, such as climate change and health, by including social applications and by emphasizing collaboration and teamwork. Our paper describes the design of curricular modules on Distributed Computing, IoT/Cybersecurity, and AI/Machine Learning. All project-based activities are designed to be collaborative, situated in contexts that are engaging to high school students, and often involve real-world world data. We piloted these modules in teacher PD workshops with 8 teachers from North Carolina, Tennessee, Massachusetts, Pennsylvania, and New York who then facilitated virtual summer camps with high school students in 2020 and 2021. Findings from teacher PD workshops as well as student camps indicate high levels of engagement in and enthusiasm for the curricular activities and topics. Post-intervention surveys suggest that these experiences generate student interest exploring these ideas further and connections to areas of interest to students.

5. Virtual Reality Education Modules for Digital Manufacturing Instruction

   Chandramouli, M. ; Jin, G. ; Heffron, J. ; Cossette, M. ; Fidan, I. ; Merrell, W. ; Welsch, C. ( July 2018 , ASEE Annual Conference proceedings)

   There is an imminent need to remedy the ‘skills gaps’ in the digital manufacturing (DM) sector as evident from the Bureau of Labor Statistics projections pointing to a decline in traditional manufacturing jobs accompanied by marked growth in digital- and computer-driven manufacturing jobs. With proven advantages such as cost benefits, material conservation, minimized labor, and enhanced precision, manufacturing industries worldwide are adapting to digital manufacturing standards on a large scale. In an effort to remedy the lack of well-defined DM career pathways and instructional framework, our NSF ATE (Advanced Technological Education) project MANEUVER (Manufacturing Education Using Virtual Environment Resources) is developing an innovative pedagogical approach using virtual reality (VR). This multimodal VR framework DM instruction targeted at 2-year and 4-year manufacturing programs, facilitates the development of VR modules for multiple modes such as desktop VR, Augmented VR, and Immersive VR. The advantages of the virtual reality framework for digital manufacturing education include: significant cost reduction, reduction in equipment and maintenance costs, ability to pre-visualize the product before manufacturing. This paper introduces the design and development process of VR education tool to simulate three different additive manufacturing machines, e.g., LutzBot™, FormLabs™, and UPrint™ and different 3D printing technologies e.g., fused deposition modeling, and selective laser sintering to allow the students experience the materials and equipment needed to create the same part using different types of equipment and different types of technology.
