A SOFTWARE ENGINEERING APPROACH FOR DESIGN OF EDUCATIONAL TECHNOLOGIESAuthor: Srikanth Kolachalama Date: 2017-02-03 Report no: IIIT/TH/2017/13 Advisor:KESAV V NORI AbstractThis thesis is driven by the idea of advancing computing to address critical challenges in the domain of education. In particular, focuses on facilitating the design of educational technologies for scale and variety, where scale is the number of systems to be developed and variety stems from a diversified range of instructional designs [consisting of varied goals, processes, content, teacher styles, learner styles and so on]. More specifically, we address this challenge in the context of adult literacy in India [287 million learners spread across 22 Indian languages and instructional designs developed by 32 state resource centers spread across India]. How to address these challenges and design educational technologies that adhere to instructional design principles, provide flexibility and are less effort intensive? This thesis presents an approach for design of educational technologies for scale and variety in education. The crux of this approach is the application of software engineering ideas like patterns, ontologies and software product lines without losing focus on instructional design. This approach consists of (i) modeling different aspects of instructional design like goals, process and content using patterns and mapping them to commonly accepted approaches like Bloom’s taxonomy and Merrill’s first principles of instruction (ii) representing these patterns using an ontology based framework that systematically captures different aspects of instructional design (iii) based on the modeling of domain through patterns and ontologies, this thesis presents a pattern oriented software product lines approach for modeling a family of instructional designs and for further semi-automatically generating eLearning Systems based on these instructional designs. The core concern of quality of instruction is mitigated by deriving patterns and ontologies from well-established and field tested methodologies and instructional material under the aegis of National Literacy Mission Authority of Government of India. Finally, we demonstrate how software tools built on top of our approach [http://rice.iiit.ac.in] can be used to semi-automatically generate eLearning Systems for flexible instructional designs and multiple Indian languages. We see that the proposed approach for scale and variety based on patterns, ontologies and software product lines could be applicable beyond adult literacy to the broad spectrum of education, and in particular to skill and school education.
