1. Board 316: Innovation Self-Efficacy: Empowering Environmental Engineering Students to Innovate

   Bolhari, Azadeh; Bielefeldt, Angela (June 2024, ASEE PEER)

   This project evaluates if and how an intervention to design a K-12 STEM activity related to water chemistry impacts the innovation self-efficacy (ISE) of junior students enrolled in a required environmental engineering course. ISE is defined as having five behavioral components: questioning, observing, experimenting, idea networking, and associational thinking. In this course, the K-12 STEM activity is designed with a team of 3 to 5 students. The activity requires that the students develop an innovative activity that demonstrates environmental engineering concepts such as acid mine drainage, ocean acidification, and contaminant removal. The student projects are scaffolded throughout the 10 weeks via intermediate submissions and meetings with a K-12 STEM teacher and design mentors. In fall 2022 a pilot of the study was conducted and relied on a quantitative survey instrument that measured ISE, innovation interest (INT), and future innovative work interest (IW). Based on the preliminary findings of factor structure, item reliability, and face validity evaluated by two faculty and two undergraduate students, small changes were made to the quantitative assessment instrument. The revised survey was deployed in the fall of 2023 in a required junior-level test course and a senior-level control course. The senior-level control course consisted of students who took the junior-level course with the K-12 STEM activity in the previous year. In 2023 the K-12 STEM activity intervention also included additional scaffolding through the addition of 3 team-based and 2 individual reflections to understand the process of ISE formation. Pre-post comparisons of the quantitative survey items will be conducted for individual students in the test and control courses. Team and individual reflections from the test course will be analyzed after the course. Potential demographic differences in ISE will be explored. Potential team-level influences will also be evaluated to understand the impact of a team’s ISE score on enhancing an individual team member’s ISE gain. Focus groups and individual interviews with students who participated in the test course will take place in spring 2024. The ISE, INT, and IW of environmental engineering students will be further assessed in spring 2024 through the ISE survey in the environmental engineering capstone design course and a junior-level creativity and entrepreneurship design course. This assessment will compare two different learning experiences on ISE, INT, and IW, the K-12 STEM education activity design with a semester-long, group-based technical design experience. Preliminary results will be presented in the NSF Grantees Poster Session.

2. Work in Progress: Formation of an engineering identity in first-year students through an intervention centered on senior design projects

   Richards, Abigail M; Anderson, Ryan; Myers, Carrie B (July 2020, ASEE annual conference exposition)

   Abstract This “work in progress” paper describes a multiyear project to study the development of engineering identity in a chemical and biological engineering program at Montana State University. The project focuses on how engineering identity may be impacted by a series of interventions utilizing subject material in a senior-level capstone design course and has the senior capstone design students serve as peer-mentors to first- and second-year students. A more rapid development of an engineering identity by first- and second-year students is suspected to increase retention and persistence in this engineering program. Through a series of timed interventions scheduled to take place in the first and second year, which includes cohorts that will serve as negative controls (no intervention), we hope to ascertain the following: (1) the extent to which, relative to a control group, exposure to a peer mentor increases a students’ engineering identity development over time compared to those who do not receive peer mentoring and (2) if the quantity and/or timing of the peer interactions impact engineering identity development. While the project includes interventions for both first- and second-year students, this work in progress paper focuses on the experiences of first year freshman as a result of the interventions and their development of an engineering identity over the course of the semester. Early in the fall semester, freshman chemical engineering students enrolled in an introductory chemical engineering course and senior students in a capstone design course were administered a survey which contained a validated instrument to assess engineering identity. The first-year course has 107 students and the senior-level course has 92 students and approximately 50% of the students in both cohorts completed the survey. Mid-semester, after the first-year students were introduced to the concepts of process flow diagrams and material balances in their course, senior design student teams gave presentations about their capstone design projects in the introductory course. The presentations focused on the project goals, design process and highlighted the process flow diagrams. After the presentations, freshman and senior students attended small group dinners as part of a homework assignment wherein the senior students were directed to communicate information about their design projects as well as share their experiences in the chemical engineering program. Dinners occurred overall several days, with up to ten freshman and five seniors attending each event. Freshman students were encouraged to use this time to discover more about the major, inquire about future course work, and learn about ways to enrich their educational experience through extracurricular and co-curricular activities. Several weeks after the dinner experience, senior students returned to give additional presentations to the freshman students to focus on the environmental and societal impacts of their design projects. We report baseline engineering identity in this paper.

3. Programming and Control of Physical Autonomous Robots via ROS 2

   Ma, Lili; Rosa, Christian; Li, Xiaohai; Wang, Yu; Mendoza, Benito; Zhang, Andy S (October 2024, Journal of computing sciences in colleges)

   This paper describes two exemplary projects on physical ROS-compatible robots (i.e., Turtlebot3 Burger and Waffle PI) for an undergraduate robotics course, aiming to foster students’ problem-solving skills through project-based learning. The context of the study is a senior-level technical elective course in the Department of Computer Engineering Technology at a primarily undergraduate teaching institution. Earlier courses in the CET curriculum have prepared students with programming skills in several commonly used languages, including Python, C/C++, Java, and MATLAB. Students’ proficiency in programming and hands-on skills makes it possible to implement advanced robotic control algorithms in this robotics course, which has a 3-hour companion lab session each week. The Robot Operating System (ROS) is an open-source framework that helps developers build and reuse code between robotic applications. Though mainly used as a research platform, instructors in higher education take action in bringing ROS and its recent release of ROS 2 into their classrooms. Our earlier work controlled a simulated robot via ROS in a virtual environment on the MATLAB-ROS-Gazebo platform. This paper describes its counterparts by utilizing physical ROS-compatible autonomous ground robots on the MATLAB-ROS2-Turtlebot3 platform. The two exemplary projects presented in this paper cover sensing, perception, and control which are essential to any robotic application. Sensing is via the robot’s onboard 2D laser sensor. Perception involves pattern classification and recognition. Control is shown via path planning. We believe the physical MATLAB-ROS2-Turtlebot3 platform will help to enhance robotics education by exposing students to realistic situations. It will also provide opportunities for educators and students to explore AI-facilitated solutions when tackling everyday problems.

4. Long-term impact of a semester-long multidisciplinary service-learning assignment in a fluid mechanics course.

   Ayala, O; Gutierrez, K; Kaipa, K; Ringleb, S; Cima, F; Kumi, I; Rhemer, D; Pazos, P; Kidd, J (June 2024, ASEE Annual Conference & Exposition)

   Seventy-three students who enrolled in a senior-year level fluid mechanics course during spring semesters from 2019-2022 were asked about their perceptions on the impact in their professional preparation of a semester-long multidisciplinary service-learning assignment. This paper evaluates their current perceived impact of the assignment (long-term impact) and whether it might have changed from when they took the course (short-term impact). A survey was sent to all former students who went through the course and participated in the assignment, with a 61.64% return rate. The survey included questions about how well they remembered the assignment (some of the students were involved in it 4 years prior to completing this survey), the relevance of the project in terms of their professional preparation, how it impacted their collaboration skills, and whether their involvement affected their interest in participating in engineering outreach activities. To determine how their perceived impact of the project on their professional preparation has changed from when they took the class to now when they are working professionals, we compare their recent responses to the responses in reflections they completed while taking the course. The information gathered in the survey also provides a means to evaluate the effectiveness of the project and identify areas for improvement, which has implications for how similar projects might be designed and enacted in the future.

5. Engaging Civil Engineering Students by Exposing them to a “Capstone-like” Experience in their Sophomore Year: A Case Study

   Sarasua, Wayne; Kaye, Nigel B.; Ogle, Jennifer H.; Benaissa, Mehdi N.; Benson, Lisa; Putman, Bradley J.; and Pfirman, Aubrie L. (June 2020, 2020 ASEE Annual Conference & Exposition)

   As part of a National Science Foundation-funded initiative to completely transform the civil engineering undergraduate program at Clemson University, a capstone-like course sequence is being incorporated into the curriculum during the sophomore year. Clemson’s NSF Revolutionizing Engineering Departments (RED) program is called the Arch Initiative. Just as springers serve as the foundation stones of an arch, the new courses are called “Springers” because they serve as the foundations of the transformed curriculum. Through a project-based learning approach, Springer courses mimic the senior capstone experience by immersing students in a semester-long practical application of civil engineering, exposing them to concepts and tools in a way that challenges students to develop new knowledge that they will build on and use during their junior and senior years. In the 2019 spring semester, a pilot of the first Springer course introduced students to three civil engineering sub-disciplines: construction management, water resources, and transportation. The remaining sub-disciplines are covered in a follow-on Springer 2 pilot. The purpose of this paper is to describe all aspects of the Springer 1 course, including course content, teaching methods, faculty resources, and the design and results of a Student Assessment of Learning Gains (SALG) survey to assess students’ learning outcomes. The feedback from the SALG indicated positive attitudes towards course activities and content. Challenges for full-scale implementation of the Springer course sequence as a requirement in the transformed curriculum are also discussed.
