Integrating Educational Vocabulary: Enhancing Learning Object Metadata Schemas

This paper explores the incorporation of educational vocabulary in learning object metadata schemas, emphasizing the importance, defining characteristics, and practical use of such vocabularies in educational settings. It delves into the need for ontology-based educational terminology, examines different metadata schemas, and highlights the impact of educational vocabulary on content structuring and retrieval. The study also provides insights into creating educational vocabulary as an ontology and offers a sample vocabulary for illustration.

  1. Incorporating Educational Vocabulary in Learning Object Metadata Schemas Jian Qin School of Information Studies Syracuse University USA jqin@syr.edu Jean Godby OCLC Online Computer Library Center Dublin, Ohio USA godby@oclc.org Educational Vocabulary -- ECDL2003

  2. Content • Defining an educational vocabulary • Use of educational vocabulary in metadata schemas • Need for educational vocabulary • Creating educational vocabulary as an ontology • Further study Educational Vocabulary -- ECDL2003

  3. Defining an educational vocabulary • A collection of terms that represent educational characteristics in learning objects and may be used as: • element or attribute tags • predefined lists of values for metadata elements Educational Vocabulary -- ECDL2003

  4. Use of educational vocabulary in metadata schemas (1) • Studied four educational metadata schemas: • Educational Markup Language (EML) • Gateway to Educational Materials (GEM) • IEEE Learning Object Metadata / IMS (LOM/IMS) • Training Exchange Definition (TED) Educational Vocabulary -- ECDL2003

  5. Use of educational vocabulary in metadata schemas (2) Frequency distribution of schema components by vocabulary type Educational Vocabulary -- ECDL2003

  6. Use of educational vocabulary in metadata schemas (3) • Findings: • Elements and other metadata components in educational category counted for 29% of all • There was a lack of terms for identifying learning objectives, models, or contexts Educational Vocabulary -- ECDL2003

  7. Use of educational vocabulary in metadata schemas (4) Educational Vocabulary -- ECDL2003

  8. Need for educational vocabulary • Learning object creators: • Need a taxonomy with a high degree of specificity for content structure markup • Collection providers: • Need learning-related terms to create finer-grained metadata • Educators and learners: • Need to retrieve and select learning objects more effectively based on their instructional and learning purpose and context Educational Vocabulary -- ECDL2003

  9. Sample educational vocabulary (1) Educational vocabulary is created as an ontology Possible use in metadata <Description> <LeaningModels>Collaborative learning—Teaming </LearningModels> </Description> Educational Vocabulary -- ECDL2003

  10. Sample educational vocabulary (2) <Description> <Objective>Action—Articulate</Objective> <Objective>Competency— Comprehension</Objective> <Objective>Context—Education for creativity</Objective> </Description> Possible use in metadata Educational Vocabulary -- ECDL2003

  11. Creating educational vocabulary as an ontology • Sources of terms: • Literature in learning theory and learning objects • Terms used in learning objects • Dewey Decimal Classification, ERIC Thesaurus • Classes: the knowledge structure • Slots: facets and connectors of classes • Instances: patterns for acquiring new vocabulary Educational Vocabulary -- ECDL2003

  12. Related research • “Adaptivity” metadata elements (Conlan et al, 2001) • DC-Edu • Learning technologies vocabulary registry (CEN/ISSS) Educational Vocabulary -- ECDL2003

  13. Summary • An educational vocabulary is necessary for: • Metadata—automatic generation and indexing • learning object authoring tools • The vocabulary should be specific enough to be used as: • Element and attribute tags • Predefined values for these elements and attributes • The vocabulary needs to be tested with learning object designers, educators, and learners Educational Vocabulary -- ECDL2003
