Design of Learning Ontology and Service Model Through Achievement Standards Profile Modeling

In Korea, national education curriculum has prepared achievement standards of all subjects for K-12 schools since 2009. Achievement standards provide practical guidelines about what has to be taught and assessed by teachers and what has to be studied and achieved by students. The educational jurisdictions, however, provide achievement standards as unstructured and textual documents, which are inappropriate and inefficient for selective searching, sharing, and usage of achievement statements for education. In this paper, we design an ontological semantic model of curriculum, achievement standards, and syllabus. Also, we define mapping rules to formalize the semantic model to RDF/OWL specification, which is based of linked open data. Our proposed semantic model supports the statements searching and browsing, sharing, modification history tracing, learning resource linking, and mapping and integration of heterogeneous standards.
