Description
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.

Description
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.

Description
The purpose of this mixed methods action research project was to address the problem of practice of incorporating foundational grammar, spelling, and punctuation (GSP) instruction into community college journalism classes through the intervention of online interactive modules called The Story Mechanics Project (SMP). The modules were developed and piloted during the first two cycles of action research. Following feedback and changes in local context influencing the intervention’s need and purpose, the modules were modified and simplified for the current research cycle. The main areas of focus were the efficacy of intervention, student perceptions of self-efficacy, and insights from designing and facilitating the intervention through a lens of critical digital pedagogy. The intervention was carried out in an online, asynchronous introductory journalism class in the Spring 2022 semester. Quantitative and qualitative data were collected from a pretest/post-test skills assessment, a post-intervention survey with a retrospective component, final course writing assignment submissions, and the researcher blog. Results showed the intervention had a positive but insignificant impact on students’ GSP skills application and that it did not significantly affect student perceptions of self-efficacy in the GSP domains; there was no significant relationship between students’ perception of self-efficacy and their application of GSP skills in their writing submissions. Pedagogical insights regarding humanizing learning, balancing tensions, and releasing control emerged from qualitative analysis. Study limitations included a small sample size and a focus on GSP errors instead of correct usage. This study collaborated the need for a more effective way to teach story mechanics.

Description
Active-duty service members pursuing college degrees face many obstacles due to their military service, such as frequent relocation, long work hours, extended field time, and deployments. While online learning makes higher education more accessible to service members, asynchronous courses can leave active-duty students feeling that online education is lacking in social or peer connection. The purpose of this action research study was to use the Community of Inquiry Framework, as well as Self-Determination Theory, to investigate the results of an intervention, called the R&R Journal, on the social presence, cognitive presence, attitude, and overall academic outcome of active-duty service members enrolled in online, asynchronous HIST 1301 at Central Texas College. This study uses a quasi-experimental concurrent mixed methods design with both treatment and comparison course groups. Results indicate that active-duty students who participated in the intervention increased in social presence, cognitive presence, and overall academic outcome over the course of HIST 1301. Implications for practice include (a) increasing social presence by encouraging peer to peer connection in an asynchronous course through deeper analysis of discussion boards, (b) increasing cognitive presence by challenging students to make personal connections to course material, and (c) increasing cognitive presence by encouraging relevant, modern-day connections to course material.
