What can learners explore?
Eight concepts provide an entry into Joseon history: Sejong, Hunminjeongeum, Confucianism, science and technology, astronomy, agricultural knowledge, medical knowledge and record culture. Selecting a star exposes related concepts; the lesson below follows the chosen concept, perspective and reading depth. Rotation and zoom help inspect relationships. They do not generate historical facts.
Starting with Hunminjeongeum, for example, learners can move from the shape of a writing system to questions of learning, communication, knowledge circulation and government. Moving to record culture opens further questions about who produced records, how they survived and what present-day readers can infer from them.
From word matching to relationships for understanding
The design grows out of history-content analysis work by Jeonghun Lee and Yuju Kang. Its intended unit of analysis is a concept’s meaning, the amount of explanatory content and its relationships to other ideas needed for understanding. An edge should therefore have an interpretable reason, with source evidence distinguished from an editor’s proposed connection.
The public prototype brings together manuscript-analysis summaries, newly authored teaching explanations and links to external resources. These are different evidence types. Demonstration coordinates are not measurements of a learner’s mental model or a biological neural network.
Reading across school levels without restricting learners
Learners can select one or several ranges: elementary, middle school, high school, university exploration and further inquiry. A younger learner may read an advanced explanation; an older learner may revisit a simpler account. These controls describe material, not an ability test or an age-based access gate.
University and further-inquiry sections are editorial learning extensions. They are not claimed to be validated developmental stages extracted from a complete university textbook corpus. A larger visible constellation or more text represents the material being explored, not a measured gain in achievement.
How the lesson changes with a choice
Life, society, science and records offer different entry points to the same subject. Prepared content blocks supply shared background and connect the chosen explanations into a reading sequence. The current public service does not ask a generative AI model to write a fresh textbook in real time.
Mrs. Jarvis is a learning-guide character. Yoyo highlights an “aha” connection. A teacher might ask students to read one account, choose another perspective, then explain what stayed the same and what changed. The educational question concerns this interpretation, beyond the visual novelty of a 3D scene.
Research questions and present status
This is a design and development research prototype. Future study can investigate how learners interpret relationships, revise explanations after comparing material and experience the interface’s enjoyable or difficult features. Satisfaction ratings or click counts alone would not demonstrate improved conceptual understanding.
This page reports no completed learning-effect estimate, verified student quotation or published evaluation. Classroom-device, school-network and class-size testing remain distinct tasks. This overview is not a published journal article or a registered study report.
A classroom sequence to try
Choose one concept and write a brief initial explanation. Compare two perspectives or two reading depths. Follow a relevant resource and look for evidence that supports, qualifies or challenges the explanation. Then describe how the initial account would be kept or revised.
Museum, archive and reference links support source inspection. A link does not imply a partnership or institutional endorsement. Availability of an exhibition or service should be checked with the institution itself.
For researchers and educational technology teams
The project invites discussion of concept maps, semantic relationships, learning progressions across school levels, flexible textbooks, browser-based 3D learning and multilingual EdTech. Evidence traceability, accessibility, translation quality and changes in learners’ explanations are useful topics for collaboration.
Researchers, educators and product teams can explore the demo and authored lesson library before contacting the planner. The project does not claim sponsorship, certification, adoption or affiliation with a technology company.
