Curation has evolved into a multifaceted artistic practice that extends beyond the mere display of artworks to encompass thematic development, dissemination of knowledge, and participation of the audience. Although traditionally seen as a specialist field, children’s innate curiosity and storytelling abilities suggest their potential as active participants in the curatorial process. To address the challenge of adapting complex curatorial concepts for young learners, this study introduces “Little Curator”, a generative mixed reality (MR) tool specifically designed to simplify and enrich the children’s curation experience. By integrating creative workflows with interactive virtual environments, “Little curator” empowers children to conceptualize themes, organize content, and present immersive visual narratives. Through this exploration, children not only acquire more art knowledge but also develop a heightened sense of self-efficacy in the complex exhibition planning. Furthermore, these “creative performances” serve as a source of inspiration for professional curators, bridging the gap between emerging and established practices in the art world.
