Adult basic and literacy education (ABLE) is a complex undertaking that serves diverse learners with a variety of needs. Although no definitive list of adult education principles exists in the literature, the following principles have been identified in multiple sources devoted to principles of effective adult education: involve learners in planning and implementing learning activities; draw upon learners' experience as a resource; cultivate self-direction in learners; create a climate that encourages and supports learning; foster a spirit of collaboration in the learning setting; and use small groups. The following are ways adult educators can improve their ABLE programs by making them more student centered and participatory in nature: involve adults in program planning and implementation by asking them to assist with orientation for new learners, appointing adults to serve on advisory boards, and/or soliciting their suggestions for learning activities; develop and/or use instructional materials that are based on students' lives; develop an understanding of learners' experiences and communities; and incorporate small groups into learning activities. ABLE programs that incorporate these recommendations will foster increasing self-directedness and critical reflection in learners, which will in turn increase adult educators' success in attracting and retaining more adults in ABLE programs.
