Chairperson, Graduate Committee: Arthur W. BangertLindsey, Heidi L.2017-10-102017-10-102017https://scholarworks.montana.edu/handle/1/12794Close to half of undergraduate students in the United States are served by community colleges. Minority, low income, and first-generation postsecondary education students utilize community colleges as a gateway to postsecondary education. Additionally, these institutions provide access to higher education for many nontraditional students, such as adults who work full time while enrolled. This study used partial least squares structural equation modeling (PLS SEM) to investigate and explore the relationship between community college student self-efficacy, engagement, and statistics conceptual understanding in the non-mathematical introductory statistics course and is based on Linninbrink & Pintrich's (2003) model for conceptual understanding. There is much research regarding statistics anxiety, statistics attitude, learning behavior, and statistics achievement where students at four year institutions or graduate students were studied, but few if any studies exist that investigate these same factors with community college students. Data for this study was collected from n=161 student volunteers at three different time points during the semester using all or a subset of the following instruments: Current Statistics Self Efficacy (CSSE) (Finney & Schraw, 2003), Survey of Attitudes Toward Statistics (SATS) (Schau, Steven, Sauphinee, & Del Vecchio, 2995), Motivated Strategies for Learning Questionnaire (MSLQ) (Pintrich, Smith, Garcia, & McKeachie, 1993), and Comprehensive Assessment of Outcomes in Statistics (CAOS) (delMas, Garfield, Ooms, & Chance, 2007). Problems with missing data were resolved with multiple imputation methods to preserve power and sample size and prevent introducing bias into the analysis. Overall, the relationships of self-efficacy and engagement explained R2=7.6% of the variance in conceptual understanding of statistics. This study found positive relationships between student conceptual understanding of statistics, selfefficacy to learn statistics and student engagement. Behavioral and cognitive engagement did not appear to mediate the influence of self-efficacy but motivational engagement was found to mediate this effect. Additionally, it was found that self-efficacy to learn statistics had a medium effect on statistical understanding at course end. Suggestions for future research are given.enCommunity collegesCollege studentsStatisticsSelf-efficacyStudents--AttitudesAcademic achievementDissertationCopyright 2017 by Heidi L. Lindsey
