   This full research-track paper demonstrates growth in computational thinking in a cohort of engineering students completing their first course in engineering at a large Southwestern university in the United States. Computational thinking has been acknowledged as a key aspect of engineering education and an intrinsic part of multiple ABET outcomes. However, computing is an area where some students have more privileges (e.g. access and exposure to meaningful use of computers) than others. Integrating computing into engineering, especially early in the curriculum, may exacerbate existing experiential disadvantages students from excluded social identities experience. Most introductory engineering programs have a component of programming and/or computational thinking. A comprehensive literature review showed that no existing computational thinking framework fully met the needs of students and professors in engineering and computer science. As a result, this team created the Engineering Computational Thinking Diagnostic (ECTD). This diagnostic was assessed and improved during the 2019-2020 academic year. Data was collected from a cohort in a first-year engineering course that included topics in mathematics, engineering problem solving, and computation. Pre- and post-test data analysis with 62 participants documents statistically significant student growth in computational thinking in this course. Significant differences were not found by gender or a limited racially-based analysis. This diagnostic is of interest and relevance to all institutions providing engineering and computing programs. The short-term impact of this research includes an innovative approach to gauge student abilities in computational thinking early in a course in order to add appropriate intervention activities into lesson plans. The long-term impact is the creation of a measurement of student learning of computational thinking in engineering for courses and programs that wish to develop this important skill in their students.

2. Evaluating the Impact of Enrichment and Professional Development Activities on REU Students

   1. Nepal, B. (July 2022, 2022 ASEE Annual Conference & Exposition)

   Research Experience for Undergraduates (REU) programs have been credited for attracting and retaining students in science and engineering who otherwise may not have considered disciplines in science and engineering as their career choices. In addition to core research activities, REU programs generally provide multiple enrichment and professional development activities for participants. While the nature and the number of professional development activities vary from one REU program to another, the most common activities include ethics and safety training, research and industry seminars, GRE workshops, writing workshops, graduate school application preparation, and industry visits. Furthermore, some of these professional development activities are also conducted in large group settings with students from other research programs beyond the REU cohort. The rationale behind combining REU students with other researchers is to create a community of learners and provide them with an opportunity to build/extend their professional network. Although professional development activities are an integral part of the REU sites, there is often very limited coverage of such activities in the existing literature on REU projects. This paper presents the impact of professional development activities on the experience of REU participants in a manufacturing REU site at a major research university in the southwestern United States. For this study, data was collected from participants by an external evaluator by using both qualitative and quantitative methods. This paper presents and describes the cumulative data from three REU cohorts. The analysis and results of the data are disaggregated by the student academic level (sophomore, junior, senior), gender, ethnicity, the type of their home institutions (research or teaching institution), and desired career paths in the future (graduate school or industry). The paper also provides a detailed discussion and implications of these findings.

3. Development and Assessment of a Combined REU/RET Program in Materials Science

   Salzman, N.; Ubic, R. (April 2017, ASEE Annual Conference proceedings)

   In this paper we present an evaluation and lessons learned from a joint Research Experience for Undergraduates (REU) and Research Experience for Teachers (RET) program focused on energy and sustainability topics within a Materials Science and Engineering program at a public university. This program brought eleven undergraduate science and engineering students with diverse educational and institutional backgrounds and four local middle and high school teachers on campus for an 8-week research experience working in established lab groups at the university. Using the Qualtrics online survey software, we conducted pre-experience and post-experience surveys of the participants to assess the effects of participating in this summer research program. At the beginning of the summer, all participants provided their definition of technical research and described what they hoped to get out of their research experience, and the undergraduate students described their future career and educational plans. At the conclusion of the summer, a post-experience survey presented participants’ with their answers from the beginning of the summer and asked them to reflect on how their understanding of research and future plans involving research changed over the course of the summer experience. Many participants evolved a new understanding of research as a result of participating in the summer experience. In particular, they better recognized the collaborative nature of research and the challenges that can arise as part of the process of doing research. Participants acquired both technical and professional skills that they found useful, such as learning new programming languages, becoming proficient at using new pieces of equipment, reviewing technical literature, and improving presentation and communication skills. Undergraduates benefited from developing new relationships with their peers, while the teacher participants benefited from developing relationships with faculty and staff at the university. While most of the participants felt that they were better prepared for future studies or employment, they did not feel like the summer research experience had a significant impact on their future career or degree plans. Finally, while almost all of the participants described their summer research experience as positive, areas for improvement included better planning and access to mentors, as well as more structured activities for the teachers to adapt their research activities for the classroom.

4. HydroLearn: Improving Students’ Conceptual Understanding and Technical Skills in a Civil Engineering Senior Design Course

   Gallagher, Melissa Ann; Byrd, Jenny; Habib, Emad; Tarboton, David G; Willson, Clinton S (July 2021, 2021 ASEE Annual Conference)

   Engineering graduates need a deep understanding of key concepts in addition to technical skills to be successful in the workforce. However, traditional methods of instruction (e.g., lecture) do not foster deep conceptual understanding and make it challenging for students to learn the technical skills, (e.g., professional modeling software), that they need to know. This study builds on prior work to assess engineering students’ conceptual and procedural knowledge. The results provide an insight into how the use of authentic online learning modules influence engineering students’ conceptual knowledge and procedural skills. We designed online active learning modules to support and deepen undergraduate students’ understanding of key concepts in hydrology and water resources engineering (e.g., watershed delineation, rainfall-runoff processes, design storms), as well as their technical skills (e.g., obtaining and interpreting relevant information for a watershed, proficiency using HEC-HMS and HEC-RAS modeling tools). These modules integrated instructional content, real data, and modeling resources to support students’ solving of complex, authentic problems. The purpose of our study was to examine changes in students’ self-reported understanding of concepts and skills after completing these modules. The participants in this study were 32 undergraduate students at a southern U.S. university in a civil engineering senior design course who were assigned four of these active learning modules over the course of one semester to be completed outside of class time. Participants completed the Student Assessment of Learning Gains (SALG) survey immediately before starting the first module (time 1) and after completing the last module (time 2). The SALG is a modifiable survey meant to be specific to the learning tasks that are the focus of instruction. We created versions of the SALG for each module, which asked students to self-report their understanding of concepts and ability to implement skills that are the focus of each module. We calculated learning gains by examining differences in students’ self-reported understanding of concepts and skills from time 1 to time 2. Responses were analyzed using eight paired samples t-tests (two for each module used, concepts and skills). The analyses suggested that students reported gains in both conceptual knowledge and procedural skills. The data also indicated that the students’ self-reported gain in skills was greater than their gain in concepts. This study provides support for enhancing student learning in undergraduate hydrology and water resources engineering courses by connecting conceptual knowledge and procedural skills to complex, real-world problems.
