Immersive learning has currently been incorporated into cell biology learning settings. It is preferable to provide a realistic experience for efficacious learning. This work-in-progress study aims to build the learning materials to envision the subcellular world of cells through raw electron microscopic data of plant cells. Transmission electron microscopic observation and three-dimensional reconstruction were performed after material preparation. The author hopes that learning materials in this work-in-progress study will provide learners with immersive experiences by allowing them to explore organelles within cells by seeing and touching.
