The purpose of this study is to determine the impact of student success in developmental mathematics classes because of their instructional delivery mode at a North Texas suburban community college. The developmental mathematics courses for this study will include Beginning Algebra, Pre-Algebra and Intermediate Algebra. Classes will be offered with face-to-face instructional mode for 15 weeks, online with no face-to-face interaction for 15 weeks, and a 8-week express online class with no face-to-face interaction. The sample of this study will be students enrolled in the three developmental mathematics classes during the fall 2011 and spring 2012 semesters. To determine whether any differences exist among students' grades in the three classes, an ex post facto design will be used, and a One-Way ANOVA test will be performed to analyze the data.
