Self-Directed Learning (SDL) is a process in which adult learners initiate their inner motivation to learn by themselves to increase their knowledge, skills and experiences from resources and evaluating learning outcomes. Knowledge Management (KM) is the process of creating, sharing, using and managing the knowledge and resources of an organization. Learners use KM to gain their knowledge. To access to these resources, the learners must know Digital Literacy Abilities (DLA). We developed a model for SDL with KM to enhance DLA: The model was synthesized from related works and verified by five experts in various fields. Data instrument was derived from focus group discussion including a five-level Likert scale of the appropriateness of the model, and experts' opinions and recommendations. Then, collected data were analyzed with content analysis; mean ([x-bar]), standard deviation (S.D.). After discussion, the model was adjusted according to the experts' recommendations. It contained three circles from inner to outer: SDL, KM, and DLA, respectively. SDL had four steps: readiness triggers, setting goal and planning, learning activities, and learning's evaluation. KM contained five steps: knowledge discovery, knowledge capture and storage, knowledge application and distribution, knowledge evaluation, and knowledge creation. DLA had four aspects: operation literacy, analysis and evaluation literacy, value and creation literacy, and social-culture-organization cooperation literacy. Overall, the results of analyzed data from the experts towards on appropriateness of the model were at high level ([x-bar] = 4.4, S.D. = 0.6). This model will be continued to implement for adult learners' activities.
