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.

Systemic advantage has a meaningful relationship with grade outcomes in students’ early STEM courses at six research universities
Large introductory lecture courses are frequently post-secondary students’ first formal interaction with science, technology, engineering, and mathematics (STEM) disciplines. Grade outcomes in these courses are often disparate across student populations, which, in turn, has implications for student retention. This study positions such disparities as a manifestation of systemic inequities along the dimensions of sex, race/ethnicity, income, and first-generation status and investigates the extent to which they are similar across peer institutions.
We examined grade outcomes in a selected set of early STEM courses across six large, public, research-intensive universities in the United States over ten years. In this sample of more than 200,000 STEM course enrollments, we find that course grade benefits increase significantly with the number of systemic advantages students possess at all six institutions. The observed trends in academic outcomes versus advantage are strikingly similar across universities despite the fact that we did not control for differences in grading practices, contexts, and instructor and student populations. The findings are concerning given that these courses are often students’ first post-secondary STEM experiences.
STEM course grades are typically lower than those in other disciplines; students taking them often pay grade penalties. The systemic advantages some student groups experience are correlated with significant reductions in these grade penalties at all six institutions. The consistency of these findings across institutions and courses supports the claim that inequities in STEM education are a systemic problem, driven by factors that go beyond specific courses or individual institutions. Our work provides a basis for the exploration of contexts where inequities are exacerbated or reduced and can be used to advocate for structural change within STEM education. To cultivate more equitable learning environments, we must reckon with how pervasive structural barriers in STEM courses negatively shape the experiences of marginalized students.

Abstract Background The first day of class helps students learn about what to expect from their instructors and courses. Messaging used by instructors, which varies in content and approach on the first day, shapes classroom social dynamics and can affect subsequent learning in a course. Prior work established the non-content Instructor Talk Framework to describe the language that instructors use to create learning environments, but little is known about the extent to which students detect those messages. In this study, we paired first day classroom observation data with results from student surveys to measure how readily students in introductory STEM courses detect non-content Instructor Talk.
Results To learn more about the instructor and student first day experiences, we studied 11 introductory STEM courses at two different institutions. The classroom observation data were used to characterize course structure and use of non-content Instructor Talk. The data revealed that all instructors spent time discussing their instructional practices, building instructor/student relationships, and sharing strategies for success with their students. After class, we surveyed students about the messages their instructors shared during the first day of class and determined that the majority of students from within each course detected messaging that occurred at a higher frequency. For lower frequency messaging, we identified nuances in what students detected that may help instructors as they plan their first day of class.
Conclusions For instructors who dedicate the first day of class to establishing positive learning environments, these findings provide support that students are detecting the messages. Additionally, this study highlights the importance of instructors prioritizing the messages they deem most important and giving them adequate attention to more effectively reach students. Setting a positive classroom environment on the first day may lead to long-term impacts on student motivation and course retention. These outcomes are relevant for all students, but in particular for students in introductory STEM courses which are often critical prerequisites for being in a major.

The STEM Excellence through Engagement in Collaboration, Research, and Scholarship (SEECRS) project at Whatcom Community College is a five-year program aiming to support academically talented students with demonstrated financial need in biology, chemistry, geology, computer science, engineering, and physics. This project is funded by an NSF S-STEM (Scholarships in Science, Technology, Engineering, and Mathematics) grant awarded in January 2017. Through an inclusive and long-range effort, the college identified a strong need for financial and comprehensive supports for STEM students. This project will offer financial, academic, and professional support to three two-year cohorts of students. The SEECRS project aims to utilize a STEM-specific guided pathways approach to strengthen recruitment, retention, and matriculation of STEM students at the community college level. Scholarship recipients will be supported through participation in the SEECRS Scholars Academy, a multi-pronged approach to student support combining elements of community building, faculty mentorship, targeted advising activities, authentic science practice, and social activities. Students are introduced to disciplines of interest through opportunities to engage in course-based undergraduate research experiences (CUREs) in Biology, Chemistry and Engineering courses, funded summer research opportunities, and seminars presented by STEM professionals. Communities of practice will be nurtured through the introduction of cohort building and faculty mentorship. Cohort development starts with a required two-credit course for all scholars that emphasizes STEM identity development, specifically focusing on identifying and coping with the ways non-dominant individuals (racial/ethnic minorities, non-male gender, lower socioeconomic status, first-generation, 2-year community college vs. 4-year institutions) are made to feel as outsiders in STEM. Each SEECRS scholar is paired with a faculty mentor who engages in ongoing mentor training. The project evaluation will determine the efficacy of the project activities in achieving their intended outcomes. Specifically, we will collect data to answer the research question: To what extent can a guided pathways approach provide a coordinated and supported STEM experience at Whatcom Community College that: (1) increases student success, and (2) positively shifts students’ STEM self-identity? The evaluation will employ a quasi-experimental research design, specifically a pretest-posttest design with a matched comparison group. Our first cohort of 14 students was selected over two application rounds (winter and summer 2017). We awarded ten full scholarships and four half-scholarships based on financial need data. Cohort demographics of note compared to institutional percentages are: females (64% vs. 57%), Hispanic (14% vs. 17%), African American (7% vs. 2%), white (79% vs. 66%), first generation college bound (43% vs. 37%). The cohort is comprised of six students interested in engineering, six in biology, and one each in geology and environmental sciences. With increased communication between the project team, our Financial Aid office, Entry and Advising, high school outreach, and the Title III grant-funded Achieve, Inspire, Motivate (AIM) Program, as well as a longer advertising time, we anticipate significantly enhancing our applicant pool for the next cohort. The results and lessons learned from our first year of implementation will be presented.more » « less

Prunuske, Amy (Ed.)Online education has grown rapidly in recent years with many universities now offering fully online degree programs even in STEM disciplines. These programs have the potential to broaden access to STEM degrees for people with social identities currently underrepresented in STEM. Here, we ask to what extent is that potential realized in terms of student enrollment and grades for a fully online degree program. Our analysis of data from more than 10,000 course-enrollments compares student demographics and course grades in a fully online biology degree program to demographics and grades in an equivalent in-person biology degree program at the same university. We find that women, first-generation to college students and students eligible for federal Pell grants constitute a larger proportion of students in the online program compared to the in-person mode. However, the online mode of instruction is associated with lower course grades relative to the in-person mode. Moreover, African American/Black, Hispanic/Latinx, Native American, and Pacific Islander students as well as federal Pell grant eligible students earned lower grades than white students and non-Pell grant eligible students, respectively, but the grade disparities were similar among both in-person and online student groups. Finally, we find that grade disparities between men and women are larger online compared to in-person, but that for first-generation to college women, the online mode of instruction is associated with little to no grade gap compared to continuing generation women. Our findings indicate that although this online degree program broadens access for some student populations, inequities in the experience remain and need to be addressed in order for online education to achieve its inclusive mission.more » « less
