An Ontology Based Modeling Framework for Design of Educational Technologies
This work addresses the problem of flexible instructional design customization for educational technologies, particularly in large-scale applications like adult literacy, though it appears incremental as it builds on existing ontology approaches.
The paper tackles the lack of strong instructional design knowledge in educational technologies and the challenge of customization by proposing an ontology-based framework for modeling instructional design aspects using domain patterns, demonstrated through a large-scale case study in adult literacy in India involving 287 million learners across 22 languages and requiring 1000 varied eLearning systems.
Despite rapid progress, most of the educational technologies today lack a strong instructional design knowledge basis leading to questionable quality of instruction. In addition, a major challenge is to customize these educational technologies for a wide range of instructional designs. Ontologies are one of the pertinent mechanisms to represent instructional design in the literature. However, existing approaches do not support modeling of flexible instructional designs. To address this problem, in this paper, we propose an ontology based framework for systematic modeling of different aspects of instructional design knowledge based on domain patterns. As part of the framework, we present ontologies for modeling goals, instructional processes and instructional materials. We demonstrate the ontology framework by presenting instances of the ontology for the large scale case study of adult literacy in India (287 million learners spread across 22 Indian Languages), which requires creation of 1000 similar but varied eLearning Systems based on flexible instructional designs. The implemented framework is available at http://rice.iiit.ac.in and is transferred to National Literacy Mission of Government of India. This framework could be used for modeling instructional design knowledge of systems for skills, school education and beyond.
