This paper aims to explain the design for immersive learning resources that include 3D holographic learning content intended to complement basic textbooks. Also, it shows a development process for a portable learning kit that is accessible and universally available for collaborative learning to increase the interest and understanding of elementary school students. When it comes to designing 3D hologram learning content, we have worked with scientific content based on the national curriculum for fifth and sixth grade levels in elementary school. We used an IAP process (A Design Process based on Iterative Agile Prototyping) for developing a tangible learning kit, which consists of a reflective mirror, a tablet holder, and a height adjustment stand, providing 3D holographic images via a tablet and an app controller. We have assessed the learning kit in order to define problems and improvements for future development. As a primary test, the 3D learning content was evaluated with student users from the perspectives of immersion, and social interaction. For the secondary test, we conducted a usability analysis from teacher’s observation and interviews focusing on tangible interaction, and convenience. As a third test, the kit was evaluated by experts in field of EdTech (Education and Technology) to reveal its weaknesses and strengths in aspects of marketability with feedback and possible improvements. Through this exploratory study, we have identified the strengths and weaknesses of this 3D hologram learning kit and defined further improvements as a universal teaching resource in the future classroom.
