Map elementary learning paths by prerequisite knowledge and age
You can see at a glance what knowledge must be acquired before learning a specific concept and at what age that concept is typically addressed. This resource breaks down the elementary curriculum into 1,862 detailed learning units and connects their dependencies in a graph. It serves as a foundational resource for educational content developers or learning platform planners who need to understand and utilize complex curricula structurally.
Structure of the connected learning map
This dataset decomposes the elementary curriculum into 1,862 'micro-topics'. Each topic is classified as one of five types: concept, procedure, expression, language, or metacognition, and includes a specific description, achievement criteria, and recommended age range. These topics are connected by 3,915 prerequisites, forming a graph with no directional cycles. For example, it explicitly states that understanding 'sound vibration' is required to find 'volume patterns', allowing you to trace learning paths backward or predict the next step.
Alignment with curriculum standards
Each learning unit is mapped to various national educational standards, including the US Common Core, the UK National Curriculum, and the Australian Curriculum v9. In particular, for the Australian Curriculum, hundreds of standard items in the Mathematics, English, Science, and HASS (Humanities and Social Sciences) domains are precisely linked to topics, and a coverage report allows you to verify which parts correspond completely. This provides useful evidence when creating content tailored to a specific country's educational standards or analyzing differences against international benchmarks.
Scope and limitations of classroom research data
Research data including teaching methods, learning activities, feedback strategies, and assessment guidelines are attached to 1,049 topics in the Science and Mathematics domains. This data was written by an agent and then fact-checked, but not all activities have been empirically verified. Some activities lack cited sources or may be reuses of existing research, so caution is required before application. The remaining 813 topics do not include research data in this release, which does not mean those topics cannot be taught.
License structure and commercial use
The database structure and relationships are distributed under the ODbL 1.0 license, while text content is under the CC BY-SA 4.0 license. This means that while derived databases must be made public, products or apps utilizing this data can remain private. It can be used for commercial product development, but contributions or improvements to the original dataset must be made public, and attribution is mandatory when used. Educational standard data follows their respective original licenses, so you must check the PROVENANCE.md file.
Pre-use verification items
This data is provided as pure JSON files with no runtime or external dependencies, making it easy to load. However, because the copyright and license conditions of educational standards are complex, you must review the original license when using standards from a specific country. Additionally, the classroom research data consists only of proposed activities, and their effectiveness in actual educational settings has not been verified, so it is appropriate to use them only as reference material. To verify data integrity, it is recommended to run the provided validation script to check checksums and structure.
