   There is a critical need for more students with engineering and computer science majors to enter into, persist in, and graduate from four-year postsecondary institutions. Increasing the diversity of the workforce by inclusive practices in engineering and science is also a profound identified need. According to national statistics, the largest groups of underrepresented minority students in engineering and science attend U.S. public higher education institutions. Most often, a large proportion of these students come to colleges and universities with unique challenges and needs, and are more likely to be first in their family to attend college. In response to these needs, engineering education researchers and practitioners have developed, implemented and assessed interventions to provide support and help students succeed in college, particularly in their first year. These interventions typically target relatively small cohorts of students and can be managed by a small number of faculty and staff. In this paper, we report on “work in progress” research in a large-scale, first-year engineering and computer science intervention program at a public, comprehensive university using multivariate comparative statistical approaches. Large-scale intervention programs are especially relevant to minority serving institutions that prepare growing numbers of students who are first in their family to attend college and who are also under-resourced, financially. These students most often encounter academic difficulties and come to higher education with challenging experiences and backgrounds. Our studied first-year intervention program, first piloted in 2015, is now in its 5th year of implementation. Its intervention components include: (a) first-year block schedules, (b) project-based introductory engineering and computer science courses, (c) an introduction to mechanics course, which provides students with the foundation needed to succeed in a traditional physics sequence, and (d) peer-led supplemental instruction workshops for calculus, physics and chemistry courses. This intervention study responds to three research questions: (1) What role does the first-year intervention’s components play in students’ persistence in engineering and computer science majors across undergraduate program years? (2) What role do particular pedagogical and cocurricular support structures play in students’ successes? And (3) What role do various student socio-demographic and experiential factors play in the effectiveness of first-year interventions? To address these research questions and therefore determine the formative impact of the firstyear engineering and computer science program on which we are conducting research, we have collected diverse student data including grade point averages, concept inventory scores, and data from a multi-dimensional questionnaire that measures students’ use of support practices across their four to five years in their degree program, and diverse background information necessary to determine the impact of such factors on students’ persistence to degree. Background data includes students’ experiences prior to enrolling in college, their socio-demographic characteristics, and their college social capital throughout their higher education experience. For this research, we compared students who were enrolled in the first-year intervention program to those who were not enrolled in the first-year intervention. We have engaged in cross-sectional 2 data collection from students’ freshman through senior years and employed multivariate statistical analytical techniques on the collected student data. Results of these analyses were interesting and diverse. Generally, in terms of backgrounds, our research indicates that students’ parental education is positively related to their success in engineering and computer science across program years. Likewise, longitudinally (across program years), students’ college social capital predicted their academic success and persistence to degree. With regard to the study’s comparative research of the first-year intervention, our results indicate that students who were enrolled in the first-year intervention program as freshmen continued to use more support practices to assist them in academic success across their degree matriculation compared to students who were not in the first-year program. This suggests that the students continued to recognize the value of such supports as a consequence of having supports required as first-year students. In terms of students’ understanding of scientific or engineering-focused concepts, we found significant impact resulting from student support practices that were academically focused. We also found that enrolling in the first-year intervention was a significant predictor of the time that students spent preparing for classes and ultimately their grade point average, especially in STEM subjects across students’ years in college. In summary, we found that the studied first-year intervention program has longitudinal, positive impacts on students’ success as they navigate through their undergraduate experiences toward engineering and computer science degrees.

2. Web-based authentic inquiry experiences in large introductory classes consistently associated with significant learning gains for all students

   Continuous calls for reform in science education emphasize the need to provide science experiences in lower-division courses to improve the retention of STEM majors and to develop science literacy and STEM skills for all students. Open or authentic inquiry and undergraduate research are effective science experiences leading to multiple gains in student learning and development. Most inquiry-based learning activities, however, are implemented in laboratory classes and the majority of them are guided inquiries. Although course-based undergraduate research experiences have significantly expanded the reach of the traditional apprentice approach, it is still challenging to provide research experiences to nonmajors and in large introductory courses. We examined student learning through a web-based authentic inquiry project implemented in a high-enrollment introductory ecology course for over a decade.

   Results from 10 years of student self-assessment of learning showed that the authentic inquiry experiences were consistently associated with significant gains in self-perception of interest and understanding and skills of the scientific process for all students—both majors and nonmajors, both lower- and upper-division students, both women and men, and both URM and non-URM students. Student performance in evaluating the quality of an inquiry report, before and after the inquiry project, also showed significant learning gains for all students. The authentic inquiry experiences proved highly effective for lower-division students, nonmajors, and women and URM students, whose learning gains were similar to or greater than those of their counterparts. The authentic inquiry experiences were particularly helpful to students who were less prepared with regard to the ability to evaluate a scientific report and narrowed the performance gap.

   These findings suggest that authentic inquiry experiences can serve as an effective approach for engaging students in high-enrollment, introductory science courses. They can facilitate development of science literacy and STEM skills of all students, skills that are critical to students’ personal and professional success and to informed engagement in civic life.

3. Quantitative and Qualitative Assessment of Large-Scale Interventions in a First-Year Experience Program

   Menezes, Gustavo B. ; Allen, Emily L. ; Ragusa, Giselle ; Schiorring, Eva ; Nerenberg, Paul ( June 2019 , ASEE Annual Conference proceedings)

   In this Work-in-Progress paper, we report on the challenges and successes of a large-scale First- Year Engineering and Computer Science Program at an urban comprehensive university, using quantitative and qualitative assessment results. Large-scale intervention programs are especially relevant to comprehensive minority serving institutions (MSIs) that serve a high percentage of first-generation college students who often face academic and socioeconomic barriers. Our program was piloted in 2015 with 30 engineering students, currently enrolls 60 engineering and computer science students, and is expected to grow to over 200 students by Fall 2020. The firstyear program interventions include: (i) block schedules for each cohort in the first year; (ii) redesigned project-based introduction to engineering and introduction to computer science courses; (iii) an introduction to mechanics course, which provides students with the foundation needed to succeed in the traditional physics sequence; and (iv) peer-led supplemental instruction (SI) workshops for Calculus, Physics and Chemistry. A faculty mentorship program was implemented to provide additional support to students, but was phased out after the first year. Challenges encountered in the process of expanding the program include administrative, such as scheduling and training faculty and SI leaders; barriers to improvement of math and science instruction; and more holistic concerns such as creating a sense of community and identity for the program. Quantitative data on academic performance includes metrics such as STEM GPA and persistence, along with the Force Concept Inventory (FCI) for physics. Qualitative assessments of the program have used student and instructor surveys, focus groups, and individual interviews to measure relationships among factors associated with college student support and to extract student perspectives on what works best for them. Four years of data tell a mixed story, in which the qualitative effect of the interventions on student confidence and identity is strong, while academic performance is not yet significantly different than that of comparison groups. One of the most significant results of the program is the development of a FYrE Professional Learning Community which includes faculty (both tenure-track and adjunct), department chairs, staff, and administrators from across the campus.

4. How do departments support their underrepresented minority doctoral students? Are they doing enough?

   A major barrier to increasing the percentage of underrepresented minority (URM) faculty in STEM fields is the small number of URM applicants for academic positions. One factor contributing to this situation is that the two-year attrition rate of URM doctoral students is nearly 50%, substantially greater than the rate for non-URM students at most institutions. Many efforts have been made to decrease the attrition, most involving direct work with doctoral students and others concentrating on institutional changes such naming a high-level administrator to coordinate recruitment and retention efforts. Often lacking in these efforts are attempts to change faculty attitudes and practices that negatively affect student retention. Three public universities including one HBCU are currently carrying out a five-year project to develop and pilot-test a department-level process to fill this gap. Why the focus on the department level? Since URM students spend most of their time in their departments as they take classes, attend seminars, conduct research, and interact informally with department faculty, staff, and other graduate students, the climate they experience and the support they receive can have a major impact on their success. In addition, changes in a department can last well beyond the end of a grant. When interventions address students directly, once they graduate there may be no lasting change in the department. When faculty attitudes and mentoring practices change, on the other hand, the changes may last and continue to help students succeed long after the grant expires. The project seeks to help department faculty increase their understanding of the issues facing underrepresented minorities in doctoral programs, identify and remedy the departmental practices that may be hindering URM student success, and examine and improve their own mentoring practices. In the project, six cohorts of faculty members and both URM and non-URM doctoral students—two cohorts at each participating university—will be assembled and surveyed. The faculty members will be asked how their departments address recruitment and retention of URM students, how they personally support and mentor their URM students, and how welcoming and supportive of URM students they perceive their department to be. The students will be asked to express their level of satisfaction with their coursework and their relationships with faculty and other graduate students, describe the learning opportunities and mentoring they have received, and discuss how welcoming and supportive of URM students their departments have been. To initiate the gathering of baseline information, the first cohort—79 faculty members, 16 URM students, and 94 non-URM students from six STEM departments at one of the universities—was surveyed. This presentation will report and discuss the results.
