The purpose of the qualitative study was to discover instructional practices used by developmental math instructors that facilitate learning and academic success of students in developmental math courses at select community colleges in Alabama in order to generate improved instructional practices in the developmental education field. Emergent data from this study could contribute to increasing student academic success in developmental math courses and subsequent college courses. The researcher explored the specific instructional practices used by developmental math instructors to facilitate learning and academic success of students in developmental math courses, the obstacles they encountered and how they overcame the obstacles, administrative support they received, and best practices regarding facilitating learning and academic success of students in developmental math courses---all of which were identified by developmental math instructors for both novice and experienced developmental math instructors. A basic qualitative design that incorporated the use of semistructured interviews, classroom observations, and document collection was utilized. Institutions holding membership to the Alabama Association for Developmental Education and institutions offering specialized services to developmental education students were chosen for referral of potential participants. A total of 28 candidates were referred, and 12 effective developmental math instructors participated. Six themes were identified: instructional practices, learned experiences, administrative support, professionally credentialed and pedagogical knowledge, diversity through varied teaching methods, and classroom assessment techniques. The findings yielded examples of how the application of constructivist theory and the concept of contextualization are progressive approaches to instructing developmental education students.
