Many methodological approaches have been utilized to predict student retention and persistence over the years, yet few have utilized a Bayesian framework. It is believed this is due in part to the absence of an established process for guiding educational researchers reared in a frequentist perspective into the realms of Bayesian analysis and educational data mining. The current study aimed to address this by providing a model-building process for developing a Bayesian network (BN) that leveraged educational data mining, Bayesian analysis, and traditional iterative model-building techniques in order to predict whether community college students will stop out at the completion of each of their first six terms. The study utilized exploratory and confirmatory techniques to reduce an initial pool of more than 50 potential predictor variables to a parsimonious final BN with only four predictor variables. The average in-sample classification accuracy rate for the model was 80% (Cohen's κ = 53%). The model was shown to be generalizable across samples with an average out-of-sample classification accuracy rate of 78% (Cohen's κ = 49%). The classification rates for the BN were also found to be superior to the classification rates produced by an analog frequentist discrete-time survival analysis model.

Although U.S. rates of college enrollment among 18-24 year olds have reached historic highs, rates of degree completion have not kept pace. This is especially evident at community colleges, where a disproportionate number of students from groups who, historically, have had low college-completion rates enroll. One way community colleges are attempting to address low completion rates is by implementing institutional interventions intended to increase opportunities for student engagement at their colleges. Utilizing logistic and linear regression analyses, this study focused on community college students, examining the association between participation in institutional support activities and student outcomes, while controlling for specific student characteristics known to impact student success in college. The sample included 746 first-time, full-time, degree-seeking students at a single community college located in the U.S. Southwest. Additional analyses were conducted for the 440 first-time, full-time, degree-seeking students in this sample who placed into at least one developmental education course. Findings indicate that significant associations exist between different types of participation in institutional interventions and various student outcomes: Academic advising was found to be related to increased rates of Fall to Spring and Fall to Fall persistence and, for developmental education students, participation in a student success course was found to be related to an increase in the proportion of course credit hours earned. The results of this study provide evidence that student participation in institutional-level support may relate to increased rates of college persistence and credit hour completion; however, additional inquiry is warranted to inform specific policy and program decision-making at the college and to determine if these findings are generalizable to populations outside of this college setting.

More than half of the students who start this year at a community college will not return to the same institution the following year. This persistent problem negatively impacts students, institutions, and society at-large. However, institutions that experience greater success in retaining students place academic advising initiatives at the core of their retention efforts. The Appreciative Advising Model (AAM) may be uniquely suited to promoting student persistence because the AAM engages a student in long-term planning, showing how their current and future academic efforts can be aligned to achieve their goals. Employing the AAM, advisors use open-ended questions to uncover a students’ dreams, and then co-construct, with the student, a set of systematic goals uniquely tailored to help the student reach their dreams. As part of this study, the AAM was implemented as an innovation at a community college advising center. Guided by a framework that includes theories of social constructivism, positive psychology, and appreciative inquiry, this qualitative action research study employed semi-structured interviews and focus groups with students and advisors to explore their perceptions and experiences related to the AAM as a potential tool to enhance community college retention. The goal of this study was to chronicle the implementation of a new advising model for a community college—the AAM—study the perceptions and experiences related to the new model, and to assess the model’s influence on a student’s likelihood of persisting at their community college. This work increases the understanding of the AAM in a community college setting and results may have implications for community colleges, advising centers, and retention efforts.
