The purpose of this study was to investigate kindergarten teachers' perceptions and demands on YouTube videos for early childhood teachers. 257 kindergarten teachers who had experience of watching YouTube videos for early childhood teachers completed a survey. The results of this study were as follows. First, compared to online teacher education programs, a key advantage of YouTube videos in terms of platform characteristics was its accessibility, while a key disadvantage was the difficulty of asking questions to the creator; a key advantage of YouTube videos in terms of content characteristics was that it could be applied directly to the practice, while a key disadvantage was that the quality of the content might not be guaranteed. Compared to off-line teacher education programs, a key advantage of YouTube videos was that the time and place could be determined freely, while a key disadvantage was the difficulty of asking questions to the creator. Second, as the demands of kindergarten teachers on YouTube videos for early childhood teachers, they preferred ‘understanding and practicing the curriculum’ as topic, kindergarten teachers as creator, and between 5 and 20 minutes as length per video. As for the support necessary for efficient watching, providing keywords to figure out the contents of the video was the most preferred. The teachers were mostly in favor of regarding YouTube videos for early childhood teachers as teacher education programs and preferred partial reflection of those. These results reveal that YouTube videos for early childhood teachers are in its early stages of sharing practical knowledge of teachers on a new platform, and suggest that active self-regulation and feedback should be preceded to improve the quality of content, prior to regarding those as part of teacher education programs.
