In this dissertation, acceleration in developmental mathematics at Utah Valley University through compression of a 4-course sequence into a 2-course sequence was examined to determine the extent to which sequence length predicted student success outcomes, including completion of, pass/fail grades in, and re-enrollment into subsequent developmental mathematics courses for students with the lowest-level incoming placement exam scores. A two-year sample of students in the pre-reform 4-course sequence and a two-year sample of students in the post-reform 2-course sequence were analyzed using binary logistic regression, controlling for age, sex, race, and attempt number were conducted to examine completion of developmental mathematics courses and enrollment into subsequent developmental mathematics courses after passing the first course. Chi-squared tests of association were also conducted to examine the relationship between sequence length and whether the lowest-level placed students passed their first or second semester in developmental mathematics coursework. The findings of this study suggested that the post-reform 2-course sequence may have a detrimental effect on student success outcomes in developmental mathematics courses for the lowest-level placed students, however broad confidence intervals prevented firm conclusions. Goodness of fit measures showed that the models created in this study do not account for a large portion of the variance in the student success outcomes, indicating that factors other than sequence length, such as Pell grant eligibility, first generation status, and other cognitive and affective characteristics would be better predictors of success. Reduced course sequences could be an effective option as part of a holistic developmental mathematics program that meets the various needs of its students. However, as an isolated change without consideration of varied ideal learning rates, a shortened sequence does not have a meaningful impact.
