The purpose of the study was to develop an action learning-based media education program for early childhood teachers in order to increase their perspectives on the importance of media education and promote their teaching competence in media education. After extensive literature review on media education, early childhood media education, and action learning, pilot studies were implemented to draw up a draft of the program; the draft was modified on the basis of the results of expert review to improve its content validity and feasibility. Next, it was tried out and evaluated in a small learning team, which consisted of six kindergarten teachers and a learning coach (one of the researchers). The materials used in each session were gathered, and the collected data were analyzed to examine the problems in the content or management of the program draft; the results of a summative evaluation were also reflected to finalize the program. The finalized program consists of seven sessions; the frequency of offline gathering declined while activities in online community increased. To be specific, the first to third sessions are mainly composed of lectures and discussions in order for early childhood teachers to understand basic subject knowledge on early childhood media education; in the forth to seventh sessions, learning takes place while the learning team(s) selects a real task of early childhood media education in practice and resolves it according to the seven stages of action learning.
