ADL DAU Sandbox

Abstract

The purpose of this project was to recreate key components of the Reference Implementation with commercially-available, open source, and customized solutions to demonstrate the value of organizations choosing to adopt the architecture to improve their ability to track competency-based learning. The DAU Sandbox contained multiple hardware and software components, including: Learning Records Stores (LRSs): collect, store, and route data about learners and their activities, activity providers: provide data to LRSs, learner records: learning and demographic data about learners, competency management system: stores competencies that are mapped to learning events, dashboards: provide users with varying access permissions to view data specific to their needs. the ultimate goal of the architecture is to be able to connect with activity providers and learner record data across multiple enclaves. For this connectivity to occur, it was vital to build the system using recognized standards, such as the IEEE 1484.12.1 Learner Object Metadata 2.0 draft standard. These standards or subsets of them were used to provide a future capability to connect to additional data providers. The DAU Sandbox served as an abbreviated version of the envisioned end architecture and was credibly able to create the competency-based learning environment as designed. During testing, data was able to be exchanged and passed through the pipes as desired. Course completions for users were successfully tied to competencies and the users who achieved them. Relevant sections of the standards were successfully applied. Opportunities to enhance system performance moving forward were identified, particularly in the areas of component maturation, security, and the Competency and Skills System (CaSS) that was used. Other successes included identifying opportunities to collect data at a more granular level, and additional business rules that could be established for score competency and experience.
