In a world that has become digital transformation, Virtual Learning Communities (VLC) can improve 21st century teaching and learning by incorporating principles of globalization and localization. This research aimed to develop a model for knowledge management of local wisdom via the VLC for instructional management. The research procedure comprised three phases: In Phase 1, the sample consisted of 376 primary education teachers obtained by quota sampling. In Phase 2, the population comprised 12 experts. In Phase 3, the sample comprised 1) 100 primary education teachers; and 2) 200 Grade 5 students, obtained by multi-stage sampling. Research data were analyzed using the mean, standard deviation, and content analysis. Research results were as follows: 1) The overall state of using local wisdom was rated at the highest level, and the problem and need for using local wisdom at the high level 2) Regarding results of the model included three main elements: 1) the components of the model, which included names, community members, community activities, knowledge on local wisdom, supporting technology, factors of knowledge construction, and measurement and evaluation; and 2) the steps of the model, which included six steps, namely, preparation for creating of the VLC, creation of the community, knowledge creation and storage, creation of a prototype and certifying of local wisdom knowledge, implementing the prototype in school, and conclusion and evaluation of knowledge management results, 3) The topmost 21st century skills of the teacher are local connections skills, the students are collaboration skills, and the students had learning achievement significantly at the 0.05 level.
