We propose a novel way for enriching curriculum and building collaboration diversity by leveraging augmented reality (AR) technologies to transport learning beyond the traditional barriers of university classroom walls and screens. We developed an interactive assignment that challenges students to define the key terms in a course by coding authentic and meaningful AR experiences. Each code extends and enhances learning with a series of well-designed scenes that integrate digital information with the real-world environment in real time, including creative text, definitions, infographics, games, music, narratives, photo galleries, videos, websites, and more. To invite people to interaction with the codes, we used sustainable materials to build an oversized AR Abacus. The students’ designs were reassembled to make vibrant prisms that slide across and around the abacus rods, thereby creating a playful augmented space for exploring and envisioning. Not only is the AR Abacus an innovative teaching tool that promotes active learning about educational media, but it also builds community by bringing people, art, story, knowledge, and technology together.
