Mathematics is a particular stumbling block for community college students in developmental course work. The present study empirically investigated student-level and teacher-level factors that influence the success of community college students enrolled in developmental mathematics courses. Specifically, numerous variables in one statistical model were examined, which included student self-efficacy (SE) beliefs in various aspects of academic engagement, previous course difficulties, full-time teaching status, and class attendance policies. Multiple regression results show that attendance was the largest predictor for higher course grades, followed by repeating a mathematics course and students’ sense of SE. In the hierarchical line modeling (HLM) model, teachers’ full-time status was a significant predictor in the model, but when teaching status was controlled for, the remaining student belief variables in the model were not statistically significant except SE in Cognitive Strategies, Self-Regulated Learn...
